DISPLAY CONTROL METHOD AND ELECTRONIC DEVICE SUPPORTING SAME

BACKGROUND
1. Field

The disclosure relates to a display control method and an electronic device supporting the same.

2. Description of Related Art

A display serves as a core interface that provides explicit processes of recognition (e.g., input) and presentation (e.g., output) of information resources. A recent electronic device is equipped with a full screen display that provides an extended screen in order to promote an advanced interaction between the display and a user.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

Implementation of a full screen display may require improvement of hardware or software in an electronic device. For example, an optical sensor (e.g., an image sensor, a fingerprint sensor, or an illuminance sensor) disposed on a front surface of the electronic device or exposed through the front surface may be disposed under a display so as not to restrict the screen expansion of the display. In this case, the display area corresponding to a disposition region of the optical sensor may include a non-pixel region where some pixels are removed to support optical functions of the optical sensor.

However, the display area corresponding to the disposition region of the optical sensor may be viewed differently from other display areas because of a reduction in resolution or brightness due to the non-pixel region, which may reduce quality of the display.

The communication module 190 may be configured to support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to another embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to yet another embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

In an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. In another embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

Referring to FIGS. 1 and 2, a display device 160 may include a display 210 and a display driver integrated circuit (DDI) 230 to control the display 210. The DDI 230 may include an interface module 231, memory 233 (e.g., buffer memory), an image processing module 235, or a mapping module 237. The DDI 230 may receive image information that contains image data or an image control signal corresponding to a command to control the image data from another component of the electronic device 101 via the interface module 231. According to an embodiment, the image information may be received from the processor 120 (e.g., the main processor 121 (e.g., an application processor)) or the auxiliary processor 123 (e.g., a graphics processing unit) operated independently from the function of the main processor 121. The DDI 230 may communicate, for example, with touch circuitry 150 or the sensor module 176 via the interface module 231. The DDI 230 may also store at least part of the received image information in the memory 233, for example, on a frame by frame basis. The image processing module 235 may perform pre-processing or post-processing (e.g., adjustment of resolution, brightness, or size) with respect to at least part of the image data. In an embodiment, the pre-processing or post-processing may be performed, for example, based at least in part on one or more characteristics of the image data or one or more characteristics of the display 210. The mapping module 237 may generate a voltage value or a current value corresponding to the image data pre-processed or post-processed by the image processing module 235. In another embodiment, the generating of the voltage value or current value may be performed, for example, based at least in part on one or more attributes of the pixels (e.g., an array, such as an red, green, and blue (RGB) stripe or a pentile structure, of the pixels, or the size of each subpixel). At least some pixels of the display 210 may be driven, for example, based at least in part on the voltage value or the current value such that visual information (e.g., a text, an image, or an icon) corresponding to the image data may be displayed via the display 210.

In yet another embodiment, the display device 160 may further include the touch circuitry 250. The touch circuitry 250 may include a touch sensor 251 and a touch sensor IC 253 to control the touch sensor 251. The touch sensor IC 253 may control the touch sensor 251 to sense a touch input or a hovering input with respect to a certain position on the display 210. To achieve this, for example, the touch sensor 251 may detect (e.g., measure) a change in a signal (e.g., a voltage, a quantity of light, a resistance, or a quantity of one or more electric charges) corresponding to the certain position on the display 210. In still another embodiment, the touch circuitry 250 may provide input information (e.g., a position, an area, a pressure, or a time) indicative of the touch input or the hovering input detected via the touch sensor 251 to the processor 120. According to an embodiment, at least part (e.g., the touch sensor IC 253) of the touch circuitry 250 may be formed as part of the display 210 or the DDI 230, or as part of another component (e.g., the auxiliary processor 123) disposed outside the display device 160.

The display device 160 may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module 176 or a control circuit for the at least one sensor. In such a case, the at least one sensor or the control circuit for the at least one sensor may be embedded in one portion of a component (e.g., the display 210, the DDI 230, or the touch circuitry 150)) of the display device 160. For example, when the sensor module 176 embedded in the display device 160 includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) corresponding to a touch input received via a portion of the display 210. As another example, when the sensor module 176 embedded in the display device 160 includes a pressure sensor, the pressure sensor may obtain pressure information corresponding to a touch input received via a partial or whole area of the display 210. In an embodiment, the touch sensor 251 or the sensor module 176 may be disposed between pixels in a pixel layer of the display 210, or over or under the pixel layer.

FIG. 3 is a diagram illustrating a first region and a second region of a display device according to an embodiment of the disclosure.

Referring to FIG. 3, a display device 160 (e.g., the display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210) of an electronic device 101 according to an embodiment may include a first region 161 and at least one second region 163. In an embodiment, the at least one second region 163 may be formed in various regions of the display 210 according to implementation thereof. The at least one second region 163 may be formed in an upper right region or an upper left region adjacent to an upper edge of the display 210. As an example, the at least one second region 163 may be formed in a region that a user's body (e.g., thumb) may easily access when the user holds the electronic device 101, and for example, the at least one second region 163 may be formed in a lower central region adjacent to a lower edge of the display 210. In an embodiment, the first region 161 may be formed to occupy the remaining area of the display 210, excluding the at least one second region 163.

In another embodiment, at least one optical sensor may be disposed under the display 210 to correspond to the at least one second region 163. The at least one optical sensor may be disposed under the display 210 so as to be vertically aligned with the at least one second region 163. In yet another embodiment, the at least one optical sensor may include at least one of an image sensor supporting capturing images of a peripheral area of the electronic device 101 (e.g., the front of the electronic device 101), an illuminance sensor for detecting the state (e.g., the amount of light) around the electronic device 101, and a biometric sensor for supporting acquisition of biometric information (e.g., fingerprint information or iris information) of a user of the electronic device 101. According to various embodiments, the area or shape of the at least one second region 163 may be variously determined depending on the size, shape, or sensing coverage of the at least one optical sensor.

In still another embodiment, each of the first region 161 and at least one second region 163 may include a plurality of pixels, and each of the plurality of pixels may include a plurality of sub-pixels. For example, one pixel may include an RGB stripe structure configured as a combination of a red sub-pixel, a green sub-pixel, and a blue sub-pixel, which are arranged on the same line, or an red, green, blue and white (RGBW) stripe structure configured as a combination of a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, which are arranged on the same line. In another example, one pixel may include an RGBG diamond Pentile structure configured as a combination of a red sub-pixel having a first size, a blue sub-pixel having a second size greater than the first size, and a plurality of green sub-pixels having a third size smaller than the first size. According to various embodiments, the areas, sizes, or shapes of the plurality of sub-pixels included in each of the plurality of pixels may be the same or different from each other. In addition, the separation distances or arrangements between the plurality of sub-pixels included in each of the plurality of pixels may be the same or different from each other.

In yet another embodiment, the at least one second region 163 may include a pixel structure that is different from the first region 161 in order to support an optical function of the optical sensor disposed to correspond to the at least one second region 163, as well as to display content corresponding to image information. The first region 161 may include a plurality of first pixel regions 161a where pixels are disposed, and the at least one second region 163 may include a plurality of second pixel regions 163a where pixels are disposed and a plurality of non-pixel regions 163b where no pixels are disposed. The first region 161 and the at least one second region 163 may support display of content on the entire area of the display 210, based on the plurality of first pixel regions 161a and the plurality of second pixel regions 163a, and the at least one second region 163 may implement light transmission through the display 210 based on the plurality of non-pixel regions 163b, thereby supporting light to enter the optical sensor from the outside or light to exit from the optical sensor to the outside.

In an embodiment, a display layer structure (or stacked structure) may differ between the first region 161 and the at least one second region 163. For example, an opaque layer (e.g., 2060 in FIG. 17C to be described later) may be disposed on the rear surface of a display panel corresponding to the at least one second region 163, and the opaque layer may be excluded from the rear surface of a display panel corresponding to the first region 161. In another embodiment, the first region 161 and the at least one second region 163 may have the same display layer structure (or stacked structure). In another example, the opaque layer may be equally disposed on the rear surfaces of the display panel corresponding to the first region 161 and the at least one second region 163, respectively, or the opaque layer may be excluded therefrom.

According to various embodiments, the plurality of second pixel regions 163a and the plurality of non-pixel regions 163b included in the at least one second region 163 may be arranged in a regular or irregular sequence. According to other embodiments, electrical wires or circuits (e.g., thin film transistors (TFTs)) related to driving of pixels may be disposed in the same or different arrangements in the plurality of second pixel regions 163a. According to still other embodiments, the area of each of the plurality of second pixel regions 163a may be the same as or different from the area of each of the plurality of non-pixel regions 163b. According to yet other embodiments, the total area of the plurality of second pixel regions 163a may be the same as or different from the total area of the plurality of non-pixel regions 163b.

According to an embodiment, the pixel density may be different between the first region 161 and the at least one second region 163 due to the plurality of non-pixel regions 163b. For example, the first region 161 may include a plurality of first pixel regions 161a in which pixels are disposed based on a first pixel density, and the at least one second region 163 may include a plurality of second pixel regions 163a in which pixels are disposed based on a second pixel density less than the first pixel density. When the first region 161 has a first pixel density of 100%, the at least one second region 163 may include a non-pixel density of 25%, 50%, or 75%, thereby having a second pixel density of 75%, 50%, or 25%, which is less than the first pixel density. According to another embodiment, based on the first pixel density and the second pixel density different from each other, the number of pixels per unit area included in the at least one second region 163 may be smaller than the number of pixels per unit area included in the first region 161.

Various functional operations of the electronic device 101 described below with reference to the drawings may be performed under direct or indirect control of a processor (e.g., 120 in FIG. 1) or a display driver integrated circuit (e.g., 230 in FIG. 2) that is electrically connected to the display device 160 (or the display 210 of the display device 160) of the electronic device 101. Hereinafter, examples of functional operations of the electronic device 101 under the control of the processor 120 will be described.

FIG. 4 is a diagram illustrating a method of controlling a display device according to an embodiment of the disclosure, FIG. 5 is a diagram illustrating a brightness level relationship between a first region and a second region of a display device according to an embodiment of the disclosure, and FIG. 6 is a diagram illustrating a third region of a display device according to an embodiment of the disclosure.

Referring to FIGS. 4 and 6, in operation 401, a processor (e.g., 120 in FIG. 1) of an electronic device 101 may identify a first brightness level in the first region 161 of a display device 160 (e.g., the display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210). The processor 120 may identify a first brightness level in the first region 161 of a display device 160 while displaying an arbitrary screen (e.g., a lock screen, a home screen, or an execution screen of an application) through the display 210. The processor 120 may identify the first brightness level of the first region 161 within a specified time range from displaying the arbitrary screen.

In operation 403, the processor 120 may determine whether or not the identified first brightness level of the first region 161 exceeds a specified threshold. According to an embodiment, the processor 120 may configure a maximum brightness level capable of being covered by at least one second region 163 of the display 210 (or capable of maximally brightening the second region 163) as the specified threshold. In this regard, referring to FIGS. 5 and 6, since at least one second region 163 may have a second pixel density less than a first pixel density of the first region 161 (or may have a plurality of non-pixel regions (163b in FIG. 3) from which pixels have been removed), the at least one second region 163 may have a maximum brightness level 510 lower than the maximum brightness level of the first region 161 by a specific ratio. For example, assuming that at least one second region 163 has a second pixel density of 25% compared to a first pixel density of 100% in the first region 161, the at least one second region 163 may have a maximum brightness level 510 corresponding to a ratio of 25% to the maximum brightness level of the first region 161 on the condition that the same driving power is supplied to a plurality of first pixel regions (e.g., 161a in FIG. 3) included in the first region 161 and a plurality of second pixel regions (e.g., 163a in FIG. 3) included the at least one second region 163. In another example, in the case where at least one second region 163 has a second pixel density of 50% compared to a first pixel density of 100% in the first region 161, the at least one second region 163 may have a maximum brightness level corresponding to a ratio of 50% to the maximum brightness level of the first region 161 on the condition that the same driving power is supplied to a plurality of first pixel regions 161a included in the first region 161 and a plurality of second pixel regions 163a included the at least one second region 163.

Based on the above description, at least one second region 163 may be controlled to have a brightness level the same as or similar to a brightness level of the first region 161 when the brightness level of the first region 161 is less than or equal to the maximum brightness level of the at least one second region 163. Alternatively, if the brightness level of the first region 161 exceeds the maximum brightness level of the at least one second region 163, the at least one second region 163 may have a brightness level lower than the brightness level of the first region 161 even it is controlled to have a maximum brightness level that may be covered.

In an embodiment, if it is determined that the first brightness level of the first region 161 exceeds a specified threshold in operation 403, the processor 120 may determine a second brightness level of at least one second region 163, which is to be controlled, in operation 405. The processor 120 may determine the second brightness level of at least one second region 163, based on at least one of a first brightness level of the first region 161, a first pixel density of the first region 161, a second pixel density of at least one second region 163, and deterioration that may possibly occur in at least one second region 163. In another embodiment, if the first brightness level of the first region 161 exceeds the specified threshold by a specified level range or more, the processor 120 may determine a maximum brightness level capable of being covered by at least one second region 163 as the second brightness level such that the at least one second region 163 has a brightness level as similar as possible to the first brightness level of the first region 161. Alternatively, if the first brightness level of the first region 161 exceeds the specified threshold by less than the specified level range, the processor 120 may determine a brightness level lowered by a specified level from the maximum brightness level of at least one second region 163 as the second brightness level in order to prevent degradation (e.g., burn-in) that may occur when the at least one second region 163 consistently has the maximum brightness level. According to various embodiments, if the first brightness level of the first region 161 exceeds the specified threshold without determining the specified level range, the processor 120 may determine any one of the maximum brightness level capable of being covered by at least one second region 163 and the brightness level lowered by a specified level from the maximum brightness level as the second brightness level of the at least one second region 163.

In operation 407, the processor 120 may identify a third region 165 of the display 210. According to an embodiment, the processor 120 may determine a third region 165 defined to include a partial region of the first region 161 and at least one second region 163. For example, the processor 120 may determine an edge region of the first region 161 as the third region 165, and in this operation, a region that extends from the edge of the display 210 to have a width covering at least one second region 163, formed adjacent to the edge, may be determined as the edge region of the first region 161. The processor 120 may determine a region defined to have a width capable of including the at least one second region 163 along the edge of the first region 161, based on the edge of the display 210, as the third region 165.

According to various embodiments, the processor 120 may dynamically determine the third region 165, based on the position of at least one second region 163. For example, in the case where the at least one second region 163 is formed in an upper right region or an upper left region adjacent to the upper edge of the display 210, the processor 120 may determine an upper edge region of the first region 161 as the third region 165. In the case where the at least one second region 163 is formed in the lower central region adjacent to the lower edge of the display 210, the processor 120 may determine a lower edge region of the first region 161 as the third region 165. As another example, in the case where the at least one second region 163 is formed in a region adjacent to the upper edge or the lower edge of the display 210, the processor 120 may determine both an upper edge region and a lower edge region of the first region 161 as the third region 165. The width of the third region 165 corresponding to the upper edge region of the first region 161 and the width of the third region 165 corresponding to the lower edge region of the first region 161 may be the same or different from each other. As yet another example, in the case where the at least one second region 163 is formed in a region adjacent to at least one of the upper edge and the lower edge of the display 210, the processor 120 may determine all edge regions of the first region 161, surrounding the central region of the first region 161 (or the central region of the display 210), as the third region 165 without separately dividing the edge regions of the first region 161.

According to various embodiments, the processor 120 may dynamically determine a third region 165 of a foldable electronic device (e.g., the electronic device 1800 to be described later in FIG. 15A). Although the electronic device 1800 according to the embodiment in FIG. 15A is illustrated as including a sensor area (e.g., 1524 in FIG. 15A) that does not overlap the display (e.g., 1600 in FIG. 15A), according to various embodiments, the sensor area 1524 may be formed in the screen area of the display 1600 (or in the lower area of the display 1600 overlapping the display 1600), similarly to the at least one second region 163 described above. A first region 161 having a large area and having a symmetrical shape with respect to the folded area (e.g., the folding area 1603 in FIG. 15A) may be formed in an unfolded state of the electronic device 1800, and the processor 120 may determine at least one of the upper edge region, the left edge region, the right edge region, and the lower edge region of the first region 161 as the third region 165, based on the position of the sensor area 1524 formed adjacent to at least one of the upper edge and the lower edge of the display 1600.

In operation 409, the processor 120 may configure the second brightness level determined by performing operation 405 as the brightness level of at least one second region 163 and the third region 165. Referring to the above description in this regard, as the first brightness level of the first region 161 exceeds a specified threshold corresponding to the maximum brightness level of at least one second region 163, the at least one second region 163 may have a brightness level lower than the first brightness level of the first region 161 even if it is controlled to have the maximum brightness level (or even if the maximum driving power is supplied). The at least one second region 163 having a lower brightness level than the first region 161 may be viewed differently from the first region 161. The processor 120 may configure the at least one second region 163 and the third region 165 corresponding to the edge region of the first region 161 to have the same second brightness level, thereby improving the issue in which the at least one second region 163 is viewed as a different spot. Additionally or alternatively, the processor 120 may configure the at least one second region 163 and the third region 165 to have the same second brightness level and apply a graphic effect having relationship with the first region 161 to the third region 165 in order to further improve the visibility issue due to a difference between the second brightness level of the at least one second region 163 and the third region 165 and the first brightness level of the first region 161. The graphic effect will be described with reference to FIG. 7 later.

In an embodiment, the processor 120 may control the supply of driving power to at least one second region 163 and the third region 165, thereby configuring the at least one second region 163 and the third region 165 to have the same second brightness level. In this operation, the processor 120 may perform control such that first driving power supplied to the at least one second region 163 is different from second driving power supplied to the third region 165. For example, as the third region 165 has a first pixel density equal to that of the first region 161 and at least one second region 163 has a second pixel density less than the first pixel density, the processor 120 may control a power management module (e.g., 188 in FIG. 1) or a battery (e.g., 189 in FIG. 1) to supply the second driving power, which is less than the first driving power supplied to the at least one second region 163, to the third region 165. For example, it may be assumed that at least one second region 163 has a second pixel density of 25% compared to a first pixel density of 100% of the first region 161. In addition, as the first brightness level of the first region 161 exceeds a specified threshold, it may be assumed that the maximum brightness level capable of being covered by the at least one second region 163 is determined as the second brightness level to be controlled for the at least one second region 163. The processor 120 may perform control such that first driving power of 100% is supplied to the at least one second region 163 in order to configure the at least one second region 163 to have the second brightness level corresponding to the maximum brightness level, and perform control such that second driving power of 25% corresponding to 25% of the first driving power of 100% is supplied to the third region 165.

According to various embodiments, the processor 120 may dynamically determine the second brightness level for at least one second region 163 and the third region 165 in a foldable electronic device (e.g., the electronic device 1800 in FIG. 15A). For example, the processor 120 may obtain information about the degree of folding (e.g., a folding angle) in an unfolded state of the electronic device 1800, and if the information about the degree of folding falls within a first angle range in which at least one second region 163 is not visible to the user's eyes substantially aligned with the electronic device 1800, may not configure the second brightness level for the at least one second region 163 and the third region 165. In another example, if the information about the degree of folding falls within a second angle range, excluding the first angle range from the entire folding angle range supported by the electronic device 1800, the processor 120 may configure the brightness levels of the at least one second region 163 and the third region 165 as the second brightness level.

If it is determined in operation 403 that the first brightness level of the first region 161 does not exceed the specified threshold, the processor 120 may determine a third brightness level to be controlled for the at least one second region 163 in operation 411. In an embodiment, the processor 120 may determine the third brightness level for the at least one second region 163, based on at least one of the first brightness level of the first region 161, the first pixel density of the first region 161, and the second pixel density of the at least one second region 163. For example, as the first brightness level of the first region 161 does not exceed the maximum brightness level (e.g., a specified threshold) capable of being covered by at least one second region 163, the processor 120 may determine the third brightness level to be controlled for the at least one second region 163 to be the same brightness level as the first brightness level of the first region 161. In another example, the processor 120 may determine the third brightness level to be controlled for at least one second region 163 to be a brightness level that is substantially similar to the first brightness level of the first region 161 but lower than the first brightness level. The brightness level lower than the first brightness level may be determined as a level at which the user is unable to recognize a difference between the first brightness level and the brightness level lower than the first brightness level. Alternatively, the processor 120 may visually provide information about candidates of brightness levels lowered from the first brightness level on stages at the time at which it is determined that the first brightness level of the first region 161 does not exceed a specified threshold and determine a brightness level selected by a user input as the third brightness level to be controlled for at least one second region 163.

In operation 413, the processor 120 may configure the brightness level of the at least one second region 163 as the third brightness level determined by performing operation 411. At least one second region 163 and the first region 161 may be configured to have the same or substantially similar brightness levels, thereby improving the issue in which the at least one second region 163 having the second pixel density less than the first pixel density of the first region 161 is viewed as a different spot from the first region 161.

According to various embodiments, the above-described operations 401 to 413 may be performed under the control of a display driver integrated circuit (e.g., 230 in FIG. 2) capable of operating independently of the processor 120. For example, when the processor 120 (or the electronic device 101) is in a low power state, sleep state, or standby state, the display driver integrated circuit 230 may control the display 210 to display an always-on-display (AOD) screen (or AOD content) and, based on the first brightness level of the first region 161 identified by performing operation 401 while displaying the AOD screen, perform operations subsequent to operation 401.

FIG. 7 is a diagram illustrating a graphic effect applied to a third region of a display device according to an embodiment of the disclosure.

Referring to FIG. 7, a processor (e.g., 120 in FIG. 1) of an electronic device 101 may configure a third region 165 of a display device 160 (e.g., a display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210) to have the second brightness level (see operation 409 in FIG. 4) and then apply a specified graphic effect to the third region 165. In an embodiment, a processor 120 may apply a gradation effect to the third region 165 as at least a part of the specified graphic effect. The processor 120 may apply a gradation effect that gradually changes from a portion of the third region 165 adjacent to the edge of the display 210 to another portion of the third region 165 adjacent to the boundary 167 between the third region 165 and the first region 161. In an embodiment, the processor 120 may control an alpha value of the display 210 for the third region 165, thereby applying a gradation effect in which the transparency of the third region 165 gradually changes between a value of 0.0 and a value of 1.0. In another embodiment, the processor 120 may apply a gradation effect in which a color gradually changes to the third region 165, and in this regard, obtain color information to be reflected in the gradation effect. For example, based on the screen displayed on the display 210 (see operation 401 in FIG. 4), the processor 120 may identify first color that is dominant in a part of the third region 165 adjacent to the edge of the display 210 and a second color dominant in another part of the third region 165 adjacent to the boundary 167, and apply a gradation effect of changing from the first color to the second color to the third region 165. Alternatively, the processor 120 may identify a color-on pixel ratio (C-OPR) (e.g., an average value of grayscales for at least one pixel in an on state (or in a state in which driving power is supplied)) of the first region 161, excluding the third region 165, and apply, to the third region 165, a gradation effect of changing between a third color corresponding to the C-OPR and at least one fourth color in the same group as the third color.

FIGS. 8A and 8B are diagrams illustrating a third region based on context of a display device according to various embodiments of the disclosure.

Referring to FIGS. 8A and 8B, a processor (e.g., 120 in FIG. 1) of an electronic device 101 may determine a width of a third region 165 in an operation (see operation 407 in FIG. 4) of identifying the third region 165 of a display device 160 (e.g., a display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210). For example, if the first brightness level of the first region 161 exceeds a specified threshold (e.g., the maximum brightness level capable of being covered by least one second region 163) by less than a specified level range (context a), the processor 120 may determine a region extending from the edge of the display 210 to have a first width w1, which may cover at least one second region 163 formed adjacent to the edge, as a third region 165 corresponding to the edge region of the first region 161. In another example, if the first brightness level of the first region 161 exceeds the specified threshold by the specified level range or more (context b), the processor 120 may determine a region extending from the edge of the display 210 to have a second width w2, which is greater than the first width w1, as a third region 165 corresponding to the edge region of the first region 161. Since a wide gradation effect may be applied to the third region 165 having the second width w2, it is possible to improve the visibility issue due to a relatively big difference between the second brightness level of at least one second region 163 and the third region 165 and the first brightness level of the first region 161.

According to various embodiments, the processor 120 may determine the width of the third region 165 depending on a change in the posture of the electronic device 101. The processor 120 may determine the width of the third region 165 corresponding to the upper edge region of the first region 161 to be different from the width of the third region 165 corresponding to the lower edge region of the first region 161 in a portrait posture of the electronic device 101 and thereafter, if it is determined that the portrait posture switches to a landscape posture, determine the width of the third region 165 corresponding to the left edge region of the first region 161 in the landscape posture (e.g., the upper edge region of the first region 161 in the portrait posture) to be the same as the width of the third region 165 corresponding to the right edge region of the first region 161 (e.g., the lower edge region of the first region 161 in the portrait posture). Conversely, even when the electronic device 101 switches from the landscape posture to the portrait posture, the width of the third region 165 may be determined in the same or similar manner as the above description. The processor 120 may determine the width of the third region 165 corresponding to the left edge region of the first region 161 to be the same as the width of the third region 165 corresponding to the right edge region of the first region 161 in the landscape posture of the electronic device 101 and thereafter, if the electronic device 101 switches from landscape posture to the portrait posture, determine the width of the third region 165 corresponding to the upper edge region of the first region 161 (e.g., the left edge region of the first region 161 in the landscape posture) to be different from the width of the third region 165 corresponding to the lower edge region of the first region 161 (e.g., the right edge region of the first region 161 in the landscape posture).

FIG. 9 is a diagram illustrating a method of controlling a display device according to an embodiment of the disclosure, and FIG. 10 is a diagram illustrating a third region of a display device according to an embodiment of the disclosure.

Various operations of an electronic device described with reference to FIG. 9 or 10 may be sequentially performed subsequent to operation 401 and operation 403 described above with reference to FIG. 4. If it is determined that the first brightness level identified for the first region of a display device exceeds a specified threshold (e.g., the maximum brightness level capable of being covered by at least one second region), the electronic device may perform the following operations.

Referring to FIGS. 9 and 10, in operation 901, a processor (e.g., 120 in FIG. 1) of an electronic device 101 may identify an on-pixel ratio (OPR) of a display 210 (e.g., a ratio of at least one pixel in an on state (or in a state in which driving power is supplied) to a plurality of pixels included in the display 210) while displaying a screen 10 (see operation 401 in FIG. 4) through a display device 160 (e.g., a display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210).

In operation 903, the processor 120 may determine whether or not the identified OPR of the display 210 exceeds a specified OPR threshold. In an embodiment, if the OPR of the display 210 exceeds the OPR threshold, the processor 120 may determine that a bright screen (or bright content) is being displayed through the display 210. Alternatively, if the OPR of the display 210 does not exceed the OPR threshold, the processor 210 may determine that a dark screen (or dark content) is being displayed through the display 210.

If it is determined in operation 903 that the OPR of the display 210 exceeds the OPR threshold, the processor 120 may determine a second brightness level to be controlled for at least one second region 163 in operation 905. If it is determined that a bright screen is being displayed through the display 210, the processor 210 may determine the maximum brightness level capable of being covered by at least one second region 163 as the second brightness level. Alternatively, the processor 210 may determine, as the second brightness level, a brightness level lowered by a specified first level from the maximum brightness level capable of being covered by at least one second region 163.

If it is determined in operation 903 that the OPR of the display 210 does not exceed the OPR threshold, the processor 120 may determine a fourth brightness level to be controlled for at least one second region 163 in operation 907. If it is determined that a dark screen is being displayed through the display 210, the processor 120 may determine, as the fourth brightness level, a brightness level lowered by a second level greater than the first level from the maximum brightness level capable of being covered by at least one second region 163.

In various embodiments, the processor 120 may sequentially perform operations 401 and 403 after performing operations 901 to 907 described above. If it is determined that the first brightness level of the first region 161 exceeds a specified threshold according to operations 401 and 403 performed after performing operations 901 to 907, the processor 120 may apply or process a result of performing operations 901 to 907 (e.g., a brightness level determined for at least one second region 163).

The processor 120 may determine a third region 165a or 165b of the display 210 after determining the brightness level of the at least one second region 163. For example, the processor 120 may determine, as the third region 165a or 165b, a region extending from the edge of the display 210 to have a width that may cover at least one second region 163 formed adjacent to the edge. In this operation, in the case where the second brightness level is determined for at least one second region 163, the processor 120 may determine a third region 165b having a second width w2 and configure at least one second region 163 and the third region 165b having the second width w2 to have the second brightness level. Alternatively, if the fourth brightness level is determined for at least one second region 163, the processor 120 may determine a third region 165a having a first width w1 less than the second width w2 and configure the at least one second region 163 and the third region 165a having the first width w1 as the fourth brightness level.

FIG. 11 is a diagram illustrating a third region of a display device according to an embodiment of the disclosure, and FIG. 12 is a diagram illustrating an example of determining the intensity of a graphic effect applied to a third region of a display device according to an embodiment of the disclosure.

Various operations of an electronic device described with reference to FIG. 11 or 12 may be sequentially performed subsequent to operation 401, operation 403, and operation 405 described above with reference to FIG. 4. For example, if it is determined that the first brightness level identified for the first region of a display device exceeds a specified threshold (e.g., the maximum brightness level capable of being covered by at least one second region) and if the second brightness level for at least one second region (e.g., the maximum brightness level capable of being covered by at least one second region or a brightness level lowered by a specified level from the maximum brightness level) is determined, the electronic device may perform the following operations.

Referring to FIGS. 11 and 12, a processor (e.g., 120 in FIG. 1) of an electronic device 101 may identify an on-pixel ratio (OPR) of the display 210 while displaying a screen 10 (see operation 401 in FIG. 4) through a display device 160 (e.g., a display (210 in FIG. 2) of the display device 160, hereinafter referred to as a display 210). In an embodiment, if the identified OPR of the display 210 exceeds a specified first OPR threshold, the processor 120 may determine that a bright screen is being displayed through the display 210, and if the identified OPR of the display 210 does not exceed the specified first OPR threshold, the processor 120 may determine that a dark screen is being displayed through the display 210. In addition, the processor 120 may identify a brightness level 20 (luminance) of the display 210 configured in the electronic device 101 by a user input at the same time as, before, or after identifying the OPR of the display 210.

In an embodiment, the processor 120 may determine the strength of a graphic effect (e.g., a gradation effect) to be applied to the display 210, based on the identified OPR and brightness level 20 of the display 210. The processor 120 may determine, as the strength of graphic effect, the width of a graphic effect (e.g., the width of the third region) to be applied to the display 210.

In another embodiment, if the OPR of the display 210 does not exceed a specified first OPR threshold and if the brightness level 20 configured for the display 210 does not exceed a specified brightness level threshold (context A), the processor 120 may determine a third region 165a having a first width w1. Alternatively, if the OPR of the display 210 does not exceed the specified first OPR threshold and if the brightness level 20 of the display 210 exceeds the specified brightness level threshold (context B), the processor 120 may determine a third region 165a having the first width w1. The processor 120 may configure a second brightness level for at least one second region 163 and the third region 165a having the first width w1, and apply a gradation effect to the third region 165a having the first width w1.

For example, the processor 120 may identify a ratio of at least one pixel in the on state to the identified OPR of the display 210 in the central region of the display 210 defined to have a predetermined area. In an embodiment, if the ratio of at least one pixel in the on state to the identified OPR of the display 210 exceeds a specified ratio in the central region of the display 210, the processor 120 may determine that a bright screen is being displayed in the central region of the display 210 and that a relatively dark screen is being displayed in areas other than the central region.

Hereinafter, another example of a structure of an electronic device to which various embodiments of the disclosure may be applied will be described with reference to FIGS. 15A, 15B, and 16.

FIG. 15A is a diagram illustrating an unfolded state of an electronic device according to an embodiment of the disclosure. FIG. 15B is a diagram illustrating a folded state of an electronic device according to an embodiment of the disclosure.

Referring to FIGS. 15A and 15B, in an embodiment, an electronic device 1800 may include a foldable housing 1500, a hinge cover 1530 that covers a foldable portion of the foldable housing 1500, and a flexible or foldable display 1600 (hereinafter, abbreviated to the “display 1600”) that is disposed in a space formed by the foldable housing 1500. In an embodiment, a surface on which the display 1600 is disposed is defined as a first surface or a front surface of the electronic device 1800. A surface opposite to the front surface is defined as a second surface or a rear surface of the electronic device 1800. A surface that surrounds a space between the front surface and the rear surface is defined as a third surface or a side surface of the electronic device 1800.

In an embodiment, the foldable housing 1500 may include a first housing structure 1510, a second housing structure 1520 including a sensor area 1524, a first back cover 1580, and a second back cover 1590. The foldable housing 1500 of the electronic device 1800 is not limited to the form and the coupling illustrated in FIGS. 15A and 15B and may be implemented by a combination and/or a coupling of other shapes or parts. In another embodiment, the first housing structure 1510 and the first back cover 1580 may be integrally formed with each other, and the second housing structure 1520 and the second back cover 1590 may be integrally formed with each other.

In an embodiment, the first housing structure 1510 and the second housing structure 1520 may be disposed on opposite sides of a folding axis (an axis A) and may have substantially symmetrical shapes with respect to the folding axis A. As will be described below, the angle or distance between the first housing structure 1510 and the second housing structure 1520 may vary depending on whether the electronic device 1800 is in a flat, folded, or intermediate state. In the illustrated embodiment, unlike the first housing structure 1510, the second housing structure 1520 may additionally include the sensor area 1524 in which various sensors are arranged, but may have a symmetrical shape in the other area.

In another embodiment, as illustrated in FIG. 15A, the first housing structure 1510 and the second housing structure 1520 may form a recess together in which the display 1600 is received. In the illustrated embodiment, due to the sensor area 1524, the recess may have two or more different widths in a direction perpendicular to the folding axis A.

For example, the recess may have (1) a first width w1 between a first portion 1510a of the first housing structure 1510 that is parallel to the folding axis A and a first portion 1520a of the second housing structure 1520 that is formed on the periphery of the sensor area 1524 and (2) a second width w2 formed by a second portion 1510b of the first housing structure 1510 and a second portion 1520b of the second housing structure 1520 that does not correspond to the sensor area 1524 and that is parallel to the folding axis A. The second width w2 may be formed to be longer than the first width w1. In other words, the first portion 1510a of the first housing structure 1510 and the first portion 1520a of the second housing structure 1520 that have asymmetrical shapes may form the first width w1 of the recess, and the second portion 1510b of the first housing structure 1510 and the second portion 1520b of the second housing structure 1520 that have symmetrical shapes may form the second width w2 of the recess. In an embodiment, the first portion 1520a and the second portion 1520b of the second housing structure 1520 may have different distances from the folding axis A. The widths of the recess are not limited to the illustrated examples. In various embodiments, the recess may have a plurality of widths by the form of the sensor area 1524 or by the portions of the first housing structure 1510 and the second housing structure 1520 that have asymmetrical shapes.

In still another embodiment, at least a part of the first housing structure 1510 and the second housing structure 1520 may be formed of metal or non-metal having strength selected to support the display 1600.

The sensor area 1524 may be formed to have a predetermined area adjacent to one corner of the second housing structure 1520. However, the arrangement, shape, and size of the sensor area 1524 are not limited to the illustrated example. In another embodiment, the sensor area 1524 may be provided in another corner of the second housing structure 1520 or in any area between an upper corner and a lower corner of the second housing structure 1520. In an embodiment, parts embedded in the electronic device 1800 to perform various functions may be exposed on the front surface of the electronic device 1800 though the sensor area 1524 or through one or more openings formed in the sensor area 1524. In various embodiments, the parts may include various types of sensors. The sensors may include, for example, at least one of a front camera, a receiver, or a proximity sensor.

In an embodiment, the first back cover 1580 may be disposed on one side of the folding axis A on the rear surface of the electronic device 1800 and may have, for example, a substantially rectangular periphery that is surrounded by the first housing structure 1510. Similarly, the second back cover 1590 may be disposed on an opposite side of the folding axis A on the rear surface of the electronic device 1800 and may have a periphery surrounded by the second housing structure 1520.

In another embodiment, the first back cover 1580 and the second back cover 1590 may have substantially symmetrical shapes with respect to the folding axis (the axis A). However, the first back cover 1580 and the second back cover 1590 do not necessarily have symmetrical shapes, and in another embodiment, the electronic device 1800 may include the first back cover 1580 and the second back cover 1590 in various shapes. In yet another embodiment, the first back cover 1580 may be integrally formed with the first housing structure 1510, and the second back cover 1590 may be integrally formed with the second housing structure 1520.

In still another embodiment, the first back cover 1580, the second back cover 1590, the first housing structure 1510, and the second housing structure 1520 may form a space in which various parts (e.g., a printed circuit board or a battery) of the electronic device 1800 are disposed. In an embodiment, one or more parts may be disposed or visually exposed on the rear surface of the electronic device 1800. For example, at least part of a sub-display 1690 may be visually exposed through a first rear area 1582 of the first back cover 1580. In another embodiment, one or more parts or sensors may be visually exposed through a second rear area 1592 of the second back cover 1590. In various embodiments, the sensors may include a proximity sensor and/or a rear camera.

Referring to FIG. 15B, the hinge cover 1530 may be disposed between the first housing structure 1510 and the second housing structure 1520 to hide internal parts (e.g., hinge structures). The hinge cover 1530 may be hidden by part of the first housing structure 1510 and part of the second housing structure 1520, or may be exposed to the outside, depending on a state (e.g., a flat state or a folded state) of the electronic device 1800.

For example, when the electronic device 1800 is in a flat state as illustrated in FIG. 15A, the hinge cover 1530 may be hidden by the first housing structure 1510 and the second housing structure 1520 and thus may not be exposed. In another example, when the electronic device 1800 is in a folded state (e.g., a fully folded state) as illustrated in FIG. 15B, the hinge cover 1530 may be exposed between the first housing structure 1510 and the second housing structure 1520 to the outside. In yet another example, when the electronic device 1800 is in an intermediate state in which the first housing structure 1510 and the second housing structure 1520 are folded with a certain angle, the hinge cover 1530 may be partially exposed between the first housing structure 1510 and the second housing structure 1520 to the outside. However, in this case, the exposed area may be smaller than that when the electronic device 1800 is in a fully folded state. In an embodiment, the hinge cover 1530 may include a curved surface.

The display 1600 may be disposed in the space formed by the foldable housing 1500. The display 1600 may be mounted in the recess formed by the foldable housing 1500 and may form almost the entire front surface of the electronic device 1800.

Accordingly, the front surface of the electronic device 1800 may include the display 1600, and a partial area of the first housing structure 1510 and a partial area of the second housing structure 1520 that are adjacent to the display 1600. In an embodiment, the rear surface of the electronic device 1800 may include the first back cover 1580, a partial area of the first housing structure 1510 that is adjacent to the first back cover 1580, the second back cover 1590, and a partial area of the second housing structure 1520 that is adjacent to the second back cover 1590.

The display 1600 may refer to a display, at least a partial area of which is able to be transformed into a flat surface or a curved surface. In an embodiment, the display 1600 may include a folding area 1603, a first area 1601 disposed on one side of the folding area 1603 (on a left side of the folding area 1603 illustrated in FIG. 15A), and a second area 1602 disposed on an opposite side of the folding area 1603 (on a right side of the folding area 1603 illustrated in FIG. 15A).

The areas of the display 1600 illustrated in FIG. 15A are illustrative, and the display 1600 may be divided into a plurality of (e.g., four or more, or two) areas according to a structure or function of the display 1600. In the embodiment illustrated in FIG. 15A, the areas of the display 1600 may be divided from each other by the folding area 1603 or the folding axis (the axis A) that extends in parallel to the y-axis. However, in another embodiment, the display 1600 may be divided into areas with respect to another folding area (e.g., a folding area parallel to the x-axis) or another folding axis (e.g., a folding axis parallel to the x-axis).

In an embodiment, the first area 1601 and the second area 1602 may have substantially symmetrical shapes with respect to the folding area 1603. However, unlike the first area 1601, the second area 1602 may include a notch 1604 that is cut according to the presence of the sensor area 1524, but in the other area, the second area 1602 may be symmetric to the first area 1601. In other words, the first area 1601 and the second area 1602 may each include a portion having a symmetrical shape and a portion having an asymmetrical shape.

Hereinafter, operations of the first housing structure 1510 and the second housing structure 1520 and the areas of the display 1600 according to states (e.g., a flat state and a folded state) of the electronic device 1800 will be described.

In an embodiment, when the electronic device 1800 is in a flat state (e.g., FIG. 15A), the first housing structure 1510 and the second housing structure 1520 may be arranged to face the same direction while forming an angle of 1680 degrees. The surface of the first area 1601 of the display 1600 and the surface of the second area 1602 thereof may face the same direction (e.g., face away from the front surface of the electronic device 1800) while forming an angle of 1680 degrees. The folding area 1603 may form the same plane together with the first area 1601 and the second area 1602.

In another embodiment, when the electronic device 1800 is in a folded state (e.g., FIG. 15B), the first housing structure 1510 and the second housing structure 1520 may be arranged to face each other. The surface of the first area 1601 of the display 1600 and the surface of the second area 1602 thereof may face each other while forming a narrow angle (e.g., an angle between 0 degrees and 10 degrees). At least part of the folding area 1603 may form a curved surface having a predetermined curvature.

In still another embodiment, when the electronic device 1800 is in an intermediate state (e.g., FIG. 15B), the first housing structure 1510 and the second housing structure 1520 may be arranged to have a certain angle therebetween. The surface of the first area 1601 of the display 1600 and the surface of the second area 1602 thereof may form an angle that is greater than that in the folded state and is smaller than that in the flat state. At least part of the folding area 1603 may form a curved surface having a predetermined curvature, and the curvature may be smaller than that in the folded state.

In other embodiments, the second side wall 2223b and the third side wall 2223c may be formed perpendicular to the first side wall 2223a. In another embodiment, the second plate 2221a, the first side wall 2223a, the second side wall 2223b, and the third side wall 2223c may be formed such that one side (e.g., a front face) of the second structure 2202 is open to receive (or enclose) at least a portion of the first structure 2201. For example, the first structure 2201 may be coupled to the second structure 2202 so as to be at least partially enclosed thereby, thereby sliding in a direction parallel to the first surface F1 or the second surface F2, for example, in the direction {circle around (1)}), while being guided by the second structure 2202.

According to various embodiments, the second side wall 2223b or the third side wall 2223c may be omitted. In an embodiment, the second plate 2221a, the first side wall 2223a, the second side wall 2223b, and/or the third side wall 2223c may be formed in separate structures and then coupled or assembled with each other. In another embodiment, the rear plate 2221b may be coupled to enclose at least a portion of the second plate 2221a.

In yet another embodiment, the second plate 2221a or the rear plate 2221b may cover at least a portion of the flexible display 2203. The flexible display 2203 may be at least partially received inside the second structure 2202, and the second plate 2221a or the rear plate 2221b may cover a portion of the flexible display 2203 received inside the second structure 2202.

According to various embodiments, the first structure 2201 may move in a first direction (e.g., the direction CO parallel to the second plate 2221a and the second side wall 2223b relative to the second structure 2202 between an open state and a closed state such that the first structure 2201 is placed at a first distance from the first side wall 2223a in the closed state and such that the first structure 2201 is placed at a second distance, which is greater than the first distance, from the first side wall 2223a in the open state. In other embodiments, the first structure 2201 may be positioned to enclose a portion of the first side wall 2223a in the closed state.

As will be described later, the second region A2 may move while being substantially guided by a roller (e.g., 2251 in FIG. 18C) mounted to the second structure 2202 so as to be received inside the second structure 2202 or exposed to the outside thereof. For example, while the first structure 2201 slides, a portion of the second region A2 may be deformed into a curved shape at a position corresponding to the roller 2251.

According to other embodiments, if the first structure 2201 moves from the closed state to the open state, the second region A2 of the display 2203 may be gradually exposed to the outside of the second structure 2202 to form substantially a plane together with the first region A1 when viewed from above of the first plate 2211a. In an embodiment, the display 2203 may be connected to at least one of a touch sensing circuit, a pressure sensor capable of measuring the intensity (pressure) of a touch, and/or a digitizer detecting a magnetic-field type stylus pen or may be disposed adjacent thereto.

A microphone for obtaining an external sound may be disposed inside the microphone holes 2247a and 2247b, and a plurality of microphones may be disposed to detect the direction of sound in various embodiments. In various embodiments, the speaker holes 2245a and 2245b and the microphone holes 2247a and 2247b may be implemented as a single hole, or a speaker (e.g., a piezo speaker) may be provided without the speaker holes 2245a and 2245b. According to an embodiment, some speaker holes 2245a (e.g., a receiver hole for a voice call) may be disposed in the first structure 2201, and other speaker holes 2245b or microphone holes 2247a and 2247b may be disposed in the second structure 2202 (e.g., one of the side surfaces 2223a, 2223b, and 2223c).

In an embodiment, the camera module 2249 may be provided in the second structure 2202 and may photograph a subject in the opposite direction of the first region A1 of the display 2203. The electronic device 2200 may include a plurality of camera modules 2249. For example, the electronic device 2200 may include a wide-angle camera, a telephoto camera, or a close-up camera, and according to an embodiment, the electronic device 200 may further include at least one of an infrared projector and at least a receiver to measure the distance to the subject.

FIG. 18C is an exploded view of an electronic device according to an embodiment of the disclosure.

Referring to FIG. 18C, an electronic device 2200 may include at least one of a first structure 2201, a second structure 2202 (e.g., a housing), a display 2203 (e.g., a flexible display), and a guide member (e.g., a roller 2251), a support sheet 2253, and a multi-joint hinge structure 2213. A portion (e.g., a second region A2) of the display 2203 may be received inside the second structure 2202 while being guided by the roller 2251. According to various embodiments, the first structure 2201 may include at least one of a first plate 2211a (e.g., a slide plate), a first bracket 2211b mounted to the first plate 2211a, and a second bracket 2211c. At least one of the first plate 2211a, the first bracket 2211b, and the second bracket 2211c may be formed of a metal material or a non-metal material (e.g., polymer). The first plate 2211a may be mounted to the second structure 2202 and may reciprocate linearly in one direction (e.g., the direction {circle around (1)} in FIGS. 18A and 18B) while being guided by the second structure 2202. In an embodiment, the first bracket 2211b may be coupled to the first plate 2211a to form a first surface F1 of the first structure 2201 together with the first plate 2211a. A first region A1 of the display 2203 may be substantially mounted on the first surface F1 so as to remain flat. The second bracket 2211c may be coupled to the first plate 2211a to form a second surface F2 of the first structure 2201 together with the first plate 2211a. According to an embodiment, at least one of the first bracket 2211b and the second bracket 2211c may be integrally formed with the first plate 2211a. The first structure 2201 or the first plate 2211a may be coupled to the second structure 2202 to slide relative to the second structure 2202.

According to various embodiments, the multi-joint hinge structure 2213 may include a plurality of bars or rods and may be connected to one end of the first structure 2201. For example, as the first structure 2201 slides, the multi-joint hinge structure 2213 may move relative to the second structure 2202 to be substantially received inside the second structure 2202 in a closed state (e.g., the state of the electronic device 2200 in FIG. 18A). According to other embodiments, even if the electronic device 2200 is in the closed state, a part of the multi-joint hinge structure 2213 may not be received inside the second structure 2202. For example, even in the closed state of the electronic device 2200, a part of the multi-joint hinge structure 2213 may be positioned outside the second structure 2202 so as to correspond to the roller 2251. The plurality of rods may extend in a straight line to be disposed parallel to a rotation axis R of the roller 2251, and may be arranged along a direction perpendicular to the rotation axis R (e.g., a direction in which the first structure 2201 slides).

According to still other embodiments, the plurality of rods may rotate around other rods adjacent thereto while remaining parallel to the other adjacent rods. Based on this, as the first structure 2201 slides, the plurality of rods may be arranged to form a curved surface or may be arranged to form a flat surface. As the first structure 2201 slides, the multi-joint hinge structure 2213 may form a curved surface at a portion facing the roller 2251 and form a flat surface at a portion not facing the roller 2251. In an embodiment, the second region A2 of the display 2203 may be mounted or supported on the multi-joint hinge structure 2213 and exposed to the outside of the second structure 2202 together with the first region A1 in an open state (e.g., the state of the electronic device 2200 in FIG. 18B). In the state in which the second region A2 is exposed to the outside of the second structure 2202, the multi-joint hinge structure 2213 may form substantially a flat surface, thereby supporting or maintaining the second region A2 in a flat state.

According to other embodiments, the second structure 2202 (e.g., a housing) may include a second plate 2221a (e.g., a rear case), a printed circuit board (not shown), a rear plate 2221b, and a third plate 2221c (e.g., a front case), and a support member 2221d. In an embodiment, the second plate 2221a may be disposed in the opposite direction of the first surface F1 of the first plate 2211a and may substantially form the appearance of the second structure 2202 or the electronic device 2200. In another embodiment, the second structure 2202 may include a first side wall 2223a extending from the second plate 2221a, a second side wall 2223b extending from the second plate 2221a to be substantially perpendicular to the first side wall 2223a, and a third side wall 2223c extending from the second plate 2221a to be substantially perpendicular to the first side wall 2223a and parallel to the second side wall 2223b. In an embodiment, at least one of the second side wall 2223b and the third side wall 2223c may be manufactured as a separate component and mounted or assembled to the second plate 2221a. In another embodiment, at least one of the second side wall 2223b and the third side wall 2223c may be integrally formed with the second plate 2221a. The second structure 2202 may accommodate an antenna for proximity wireless communication, an antenna for wireless charging, or an antenna for magnetic secure transmission (MST) in a space that does not overlap the multi-joint hinge structure 2213.

According to various embodiments, the rear plate 2221b may be coupled to the outer surface of the second plate 2221a or may be formed integrally with the second plate 2221a. In an embodiment, the second plate 2221a may be formed of a metal or a polymer material, and the rear plate 2221b may be formed of a material such as metal, glass, synthetic resin, or ceramic, thereby providing a decorative effect for the exterior of the electronic device 2200. In an embodiment, at least one of the second plate 2221a and the rear plate 2221b may be formed of a material that at least partially transmits light. Based on this, in the state in which a portion (e.g., the second region A2) of the display 2203 is received inside the second structure 2202, the electronic device 2200 may output visual information using the portion (e.g., an auxiliary display area) of the received display 2203, which is received inside the second structure 2202. The portion (e.g., an auxiliary display area) of the display 2203 may output visual information and provide the same to the outside of the second structure 2202 while being received inside the second structure 2202.

According to various embodiments, the third plate 2221c may be formed of a metal or polymer material and coupled to at least one of the second plate 2221a (e.g., a rear case), the first side wall 2223a, the second side wall 2223b, and the third side wall 2223c to form an inner space of the second structure 2202. In various embodiments, the third plate 2221c may be referred to as a front case, and the first plate 2211a of the first structure 2201 may slide while substantially facing the third plate 2221c. In other embodiments, the first side wall 2223a may be configured as a combination of a first side wall portion 2223a-1 extending from the second plate 2221a and a second side wall portion 2223a-2 formed on one edge of the third plate 2221c. In another embodiment, the first side wall portion 2223a-1 may be coupled to surround one edge of the third plate 2221c, for example, the second side wall portion 2223a-2, and in this case, the first side wall portion 2223a-1 itself may form the first side wall 2223a.

According to various embodiments, the support member 2221d may be disposed in the space between the second plate 2221a and the third plate 2221c and have a planar shape formed of a metal or polymer material. The support member 2221d may provide an electromagnetic shielding structure in the inner space of the second structure 2202 or improve the mechanical rigidity of the second structure 2202. In an embodiment, the multi-joint hinge structure 2213 and a partial area (e.g., the second region A2) of the display 2203, when received inside the second structure 2202, may be positioned in the space between the second plate 2221a and the support member 2221d. According to other embodiments, the printed circuit board (not shown) may be disposed in the space between the third plate 2221c and the support member 2221d. The printed circuit board may be accommodated in a space inside the second structure 2202, which is separated by the support member 2221d from the space in which the multi-joint hinge structure 2213 and/or a partial area of the display 2203 is received. At least one of a processor, a memory, and an interface may be disposed on the printed circuit board. The interface may include, for example, at least one of a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, and an audio interface.

According to still other embodiments, the display 2203 may include a flexible display based on an organic light-emitting diode and may be at least partially deformed into a curved shape while maintaining a generally planar shape. In an embodiment, the first region A1 of the display 2203 may be mounted or attached to the first surface F1 of the first structure 2201 to have a substantially flat shape. The second region A2 of the display 2203 may extend from the first region A1 to be supported or attached to the multi-joint hinge structure 2213. For example, the second region A2 of the display 2203 may extend along the sliding movement direction of the first structure 2201 and may be received inside the second structure 2202 together with the multi-joint hinge structure 2213 so as to be at least partially deformed to a curved shape according to the deformation of the multi-joint hinge structure 2213.

According to various embodiments, as the first structure 2201 slides on the second structure 2202, the area of the display 2203 exposed to the outside may vary. The electronic device 2200 (or the processor) may change the region of the display 2203 to be activated based on the area of the display 2203 exposed to the outside. For example, in an open state or in an intermediate state between a closed state and an open state, the electronic device 2200 may activate a region of the second structure 2202 exposed to the outside among the total area of the display 2203. As another example, in the closed state, the electronic device 2200 may activate the first region A1 of the display 2203 and deactivate the second region A2. According to other embodiments, in the closed state, if there is no user input for a specified time (e.g., 30 seconds or 2 minutes), the electronic device 2200 may deactivate the entire region of the display 2203. According to still other embodiments, in the state in which the entire region of the display 2203 is inactive, the electronic device 2200 may provide visual information through a partial area (e.g., the auxiliary display area corresponding to a portion of the second plate 2221a and/or rear plate 2221b made of a material that transmits light) of the display 2203 depending on a situation (e.g., a notification according to configuration by a user, a missed call notification, or a message arrival notification).

According to various embodiments, in the open state of the electronic device 2200, substantially the entire area (e.g., the first region A1 and the second region A2) of the display 2203 may be exposed to the outside, and the region first A1 and the second region A2 may be disposed to form a plane. In an embodiment, even if the electronic device 2200 is in the open state, a portion (e.g., one end) of the second region A2 may be positioned to correspond to the roller 2251, and the portion of the second region A2 corresponding to the roller 2251 may remain in a curved shape.

According to other embodiments, the roller 2251 (e.g., a guide member) may be rotatably mounted to the second structure 2202 at a position adjacent to one edge of the second structure 2202 (e.g., the second plate 2221a). The roller 2251 may be disposed adjacent to the edge IE of the second plate 2221a parallel to the first side wall 2223a. According to various embodiments, another side wall may extend from the edge IE of the second plate 2221a adjacent to the roller 2251, and the another side wall adjacent to the roller 2251 may be substantially parallel to the side wall 2223a. In various embodiments, the side wall of the second structure 2202 adjacent to the roller 2251 may be formed of a material that transmits light, and a portion of the second region A2 may provide visual information by passing through the portion of the second structure 2202 while being received in the second structure 2202.

According to still other embodiments, one end of the roller 2251 may be rotatably coupled to the second side wall 2223b and the opposite end thereof may be rotatably coupled to the third side wall 2223c. For example, the roller 2251 may be mounted to the second structure 2202 so as to rotate about the rotation axis R perpendicular to the sliding movement direction of the first structure 2201 (e.g., the direction {circle around (1)} in FIG. 18A or 18B). For example, the rotation axis R may be formed on one edge of the second plate 2221a so as to be substantially parallel to the first side wall 2223a but spaced apart from the first side wall 2223a. In an embodiment, the gap between the outer circumferential surface of the roller 2251 and the inner surface of the edge of the second plate 2221a may form an entrance through which the multi-joint hinge structure 2213 or the display 2203 enter the second structure 2202.

According to various embodiments, when the display 2203 is deformed into a curved shape, the roller 2251 may maintain the radius of curvature of the display 2203 to a certain degree, thereby suppressing excessive deformation of the display 2203. The excessive deformation may indicate that the display 2203 is deformed to have a small radius of curvature enough to damage pixels or signal wires included in the display 2203. The display 2203 may be moved or deformed while being guided by the roller 2251 and may be protected from damage due to the excessive deformation. In various embodiments, the roller 2251 may rotate while the multi-joint hinge structure 2213 or the display 2203 is inserted into the second structure 2202 or drawn out thereof. For example, the roller 2251 may suppress friction between the multi-joint hinge structure 2213 (or the display 2203) and the second structure 2202, thereby facilitating the multi-joint hinge structure 2213 (or the display 2203) to be inserted into the second structure 2202 or drawn out thereof.

According to other embodiments, the support sheet 2253 may be formed to include a material having flexibility and a certain degree of elasticity, for example, at least one of silicone and rubber, and may be mounted or attached to the roller 2251 so as to be selectively wound around the roller 2251 according to the rotation of the roller 2251. In the illustrated embodiment, a plurality of (e.g., four) support sheets 2253 may be arranged along the direction of the rotation axis R of the roller 2251. The plurality of support sheets may be mounted to the roller 2251 at predetermined intervals between each other and may extend in a direction perpendicular to the rotation axis R of the roller 2251. In another embodiment, one support sheet may be mounted or attached to the roller 2251. For example, the one support sheet may have a size and a shape capable of covering the disposition region of the illustrated plurality of (e.g., four) support sheets and areas between the plurality of support sheets. In various embodiments, the quantity, sizes, or shapes of the support sheets 2253 may be varied as appropriate. In other embodiments, the support sheet 2253 may be rolled around the outer circumferential surface of the roller 2251 or unrolled from the roller 2251 to a flat shape between the display 2203 and the third plate 2221c according to the rotation of the roller 2251. In various embodiments, the support sheet 2253 may be referred to as a support belt, an auxiliary belt, a support film, or an auxiliary film.

According to still other embodiments, an end of the support sheet 2253 may be connected to the first structure 2201, for example, the first plate 2211a (e.g., a slide plate) of the first structure 2201, and may be wound around the roller 2251 in the closed state of the electronic device 2200 (e.g., the state of the electronic device 2200 in FIG. 18A). Based on this, as the first plate 2211a moves according to the open state of the electronic device 2200 (e.g., the state of the electronic device 2200 in FIG. 18B), the support sheet 2253 may be gradually positioned between the second structure 2202 (e.g., the third plate 2221c) and the display 2203 (e.g., the second region A2) or between the second structure 2202 (e.g., the third plate 2221c) and the multi-joint hinge structure 2213. At least a portion of the support sheet 2253 may be positioned to face the multi-joint hinge structure 2213 and selectively wound around the roller 2251 according to the sliding movement of the first plate 2211a. In various embodiments, the support sheet 2253 may be generally disposed in contact with the multi-joint hinge structure 2213, but the portion thereof wound around the roller 2251 may be substantially separated from the multi-joint hinge structure 2213.

According to various embodiments, the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may vary depending on the degree to which the support sheet 2253 is wound around the roller 2251. As the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a is reduced, foreign substances may be prevented from entering therethrough, but if the distance is too small, the display 2203 and the second plate 2221a may come into contact with or rub against each other. If the display 2203 and the second plate 2221a come into contact with or rub against each other, the surface of the display 2203 may be damaged or the sliding operation of the first structure 2201 may be hindered.

According to other embodiments, as the support sheet 2253 is wound around the roller 2251 in the closed state of the electronic device 2200 (e.g., the state of the electronic device 2200 in FIG. 18A), the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may be reduced while the surface of the display 2203 is not in contact with the second plate 2221a. For example, as the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a is reduced, foreign substances may be prevented from flowing into the second structure 2202. In an embodiment, if the electronic device 2200 switches to the open state, the support sheet 2253 may gradually move from the roller 2251 to the space between the second structure 2202 (e.g., the second plate 2221a or the third plate 2221c) and the multi-joint hinge structure 2213 according to the movement of the first structure 2201 (e.g., the first plate 2211a). For example, as the first structure 2201 moves, the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may gradually increase, thereby suppressing friction or contact between the display 2203 and other structures (e.g., the second plate 2221a) and preventing the surface of the display 2203 from being damaged according thereto. In still other embodiments, the support sheet 2253 may gradually increase in thickness thereof from one end (e.g., the portion fixed to the roller 2251) to the other end (e.g., the portion fixed to the first plate 2211a). Using the thickness profile of the support sheet 2253, the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may be adjusted in the closed state and the open state of the electronic device 2200.

According to various embodiments, the electronic device 2200 may include one or more elastic members 131 and 133 (e.g., a low-density elastic body (sponge) or brush). The electronic device 2200 may include a first elastic member 131 mounted to one end of the display 2203, and further include a second elastic member 2233 mounted to the inner surface of the edge of the second plate 2221a according to an embodiment. The first elastic member 2231 may be substantially disposed in the inner space of the second structure 2202 and positioned to correspond to the edge of the second plate 2221a in the open state of the electronic device 2200. In an embodiment, the first elastic member 2231 may move in the inner space of the second structure 2202 according to the sliding movement of the first structure 2201. In an embodiment, if the first structure 2201 moves according to switching of the electronic device 2200 from the closed state to the open state, the first elastic member 2231 may move toward the edge of the second plate 2221a. In a situation in which the electronic device 2200 switches to the open state, the first elastic member 2231 may come into contact with the inner surface of the edge of the second plate 2221a. For example, in the open state of the electronic device 2200, the first elastic member 2231 may seal the gap between the inner surface of the edge of the second plate 2221a and the surface of the display 2203. In another embodiment, if the first structure 2201 moves according to switching of the electronic device 2200 from the closed state to the open state, the first elastic member 2231 may move while being in contact with the second plate 2221a. In this case, if a foreign substance is introduced into the gap between the second region A2 and the second plate 2221a of the display 2203 in the closed state of the electronic device 2200, the first elastic member 2231 may discharge the foreign substance to the outside of the second structure 2202 when the electronic device 2200 switches to the open state.

According to other embodiments, the second elastic member 2233 may be attached to the inner surface of the edge of the second plate 2221a and disposed to substantially face the inner surface of the display 2203. In the closed state of the electronic device 2200, the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may be substantially determined by the second elastic member 2233. In an embodiment, in the closed state of the electronic device 2200, the second elastic member 2233 may come into contact with the surface of the display 2203, thereby substantially sealing the gap between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a. Since the second elastic member 2233 may be formed of a low-density elastic body (e.g., a sponge) or brush, it may not damage the surface of the display 2203 even in direct contact with the display 2203. In another embodiment, as the first structure 2201 moves when the electronic device 2200 switches to the open state, the distance between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a may be increased. For example, the second region A2 of the display 2203 may be gradually exposed to the outside of the second structure 2202 while the display 2203 does not substantially come into contact with or rub against the second elastic member 2233. In an embodiment, when the electronic device 2200 is in the open state, the first elastic member 2231 may come into contact with the second elastic member 2233. For example, the first elastic member 2231 and the second elastic member 2233 that are in contact with each other in the open state of the electronic device 2200 may seal the gap between the surface of the display 2203 and the inner surface of the edge of the second plate 2221a, thereby blocking inflow of foreign substances.

According to still other embodiments, the electronic device 2200 may further include at least one of a guide rail 2255 and an actuating member 2257. The guide rail 2255 may be mounted to the second structure 2202, for example, the third plate 2221c, to guide the sliding movement of the first structure 2201 (e.g., the first plate 2211a). The actuating member 2257 may include a spring or a spring module that provides an elastic force in a direction in which both ends of the actuating member 2257 go far away from each other. In an embodiment, one end of the actuating member 2257 may be rotatably supported by the second structure 2202, and the opposite end thereof may be rotatably supported by the first structure 2201. According to various embodiments, when the first structure 2201 slides, both ends of the actuating member 2257 may be located closest to each other (hereinafter, referred to as a closest point) at one section between the closed state and the open state of the electronic device 2200. In a section between the closest point and the closed state of the electronic device 2200, the actuating member 2257 may provide an elastic force to the first structure 2201 in a direction of moving toward the closed state, and in a section between the closest point and the open state of the electronic device 2200, the actuating member 2257 may provide an elastic force to the first structure 2201 in a direction of moving toward the open state.

Various operations of the electronic device described with reference to FIGS. 19A and 19B may be sequentially performed subsequent to operation 405 described above with reference to FIG. 4. If it is determined that a first brightness level identified for a first region of the display device exceeds a specified threshold (e.g., the maximum brightness level capable of being covered by at least one second region) and if a second brightness level to be configured for at least one second region (e.g., the maximum brightness level capable of being covered by at least one second region or a brightness level lowered by a specified level from the maximum brightness level) is determined, the electronic device may identify a third region according to the following embodiment.

Referring to FIGS. 19A and 19B, a processor (e.g., 120 in FIG. 1) of an electronic device 2200 according to various embodiments may identify a state of the electronic device 2200 in an operation of determining a third region 165a or 165b defined to include a portion of a first region 161a or 161b and at least one second region 163 of the display 2203. For example, when determining the third region of the display 2203, the processor 120 may determine whether the electronic device 2200 is operated while a first structure (e.g., 2201 in FIG. 18A) is in a closed state (a) with respect to a second structure (e.g., 2202 in FIG. 18A) or while the first structure 2201 is in an open state (b) with respect to second structure 2202.

In an embodiment, if the electronic device 2200 is determined to be in the closed state (a), the processor 120, based on the position of at least one second region 163 formed adjacent to at least one of an upper edge or a lower edge of the display 2203, may determine a third region 165a defined to have a width including the at least one second region 163 in at least one of an upper edge region, a left edge region, a right edge region, and a lower edge region of the first region 161a (e.g., the region A1 in FIG. 18B). Similarly, if the electronic device 2200 is determined to be in the open state (b), the processor 120 may determine a third region 165b having a width capable of covering at least one second region 163 in at least one of an upper edge region, a left edge region, a right edge region, and a lower edge region of the extended first region 161b (e.g., a combination of the region A1 and the region A2 in FIG. 18B). According to the various embodiments described above, the width of the third region 165a or 165b may be determined to be the same or different from each other in at least one of the upper edge region, the left edge region, the right edge region, and the lower edge region of the first region 161a or 161b, which is determined as the third region 165a or 165b.

In another embodiment, after the determination of the third region 165a or 165b or after the brightness of at least one second region 163 and the third region 165a or 165b is configure as the second brightness level according to the determination of the third region 165a or 165b, the processor 120 may monitor an event for switching the state of the electronic device 2200. The processor 120 may identify an event for switching from the closed state to the open state of the electronic device 2200 or an event for switching from the open state to the closed state thereof.

In yet another embodiment, according to the occurrence of an event for switching the state of the electronic device 2200, the processor 120 may change or adjust the third region 165a or 165b determined (or configured as the second brightness level). According to an embodiment, if the electronic device 2200 switches from the closed state (a) to the open state (b), a portion (e.g., the region A2 in FIG. 18B) of the display 2203 may be exposed to the outside of the second structure 2202 while being guided by the roller (e.g., 2251 in FIG. 18C) mounted to the second structure 2202, and accordingly, the first region 161b in the open state (b) may have an expanded area, compared to the first region 161a in the closed state (a). In response to the first region 161b extended in the open state (b), the processor 120 may change or adjust the third region 165a defined in at least one of the upper edge region, the left edge region (or the right edge region), and the lower edge region of the first region 161a in the closed state (a). The processor 120 may change or adjust the third region 165a defined in at least one of the upper edge region and the lower edge region of the first region 161a in the closed state (a) into to the third region 165b extending in the direction (e.g., the direction {circle around (1)} in FIG. 18A or 18B) in which the electronic device 2200 switches the state, and change or adjust the third region 165a defined in the left edge region (or the right edge region) of the first region 161a in the closed state (a) into to the third region 165b to be moved to the left edge region (or the right edge region) of the extended first region 161b in the open state (b).

According to yet another embodiment, if the electronic device 2200 switches from the open state (b) to the closed state (a), a portion (e.g., the region A2 in FIG. 18B) of the display 2203 may be received inside the second structure 2202 while being guided by the roller (e.g., 2251 in FIG. 18C) mounted to the second structure 2202, and accordingly, the first region 161a in the closed state (a) may have a reduced area compared to the first region 161b in open state (b). In response to the first region 161a reduced in the closed state (a), the processor 120 may change or adjust the third region 165b defined in at least one of the upper edge region, the left edge region (or the right edge region), and the lower edge region of the first region 161b in the open state (b). For example, the processor 120 may change or adjust the third region 165b defined in at least one of the upper edge region and the lower edge region of the first region 161b in the open state (b) into to the third region 165a reduced in the direction (e.g., the direction {circle around (1)} in FIG. 18A or 18B) in which the electronic device 2200 switches the state, and change or adjust the third region 165b defined in the left edge region (or the right edge region) of the first region 161b in the open state (b) into to the third region 165a to be moved to the left edge region (or the right edge region) of the reduced first region 161a in the closed state (a).
