ELECTRONIC DEVICE FOR CONTROLLING DISPLAY POSITION OR AREA OF IMAGE ON BASIS OF CHANGE OF CONTENT OF IMAGE

TECHNICAL FIELD

Embodiments disclosed in the disclosure relate to technologies of adjusting an area while moving a location of content of an image associated with an application displayed on a display and preventing degradation generated by displaying the same running screen for a long time.

BACKGROUND ART

An electronic device may include a display displaying an image associated with an application. The image may include a variety of content depending on a type or an operation state of an application which is running. The content of the image may be displayed while moving and may be displayed on a certain location for a long time. When content maintains a certain location, the display may display a certain screen.

Meanwhile, when a display panel such as an organic light emitting diode (OLED) panel displays a certain screen for a long time, the display displaying the image may be degraded and an afterimage may occur. When degradation or burn-in occurs in a light emitting element making up a pixel of the display, the luminance of the pixel may be degraded to result in uniformity of image representation.

DISCLOSURE

The communication module 190 may 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.

According to an 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 an 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)).

FIG. 2 is a block diagram 200 illustrating the display device 160, controlling position or area of image based on a change of contents of image, according to various embodiments. Referring to FIG. 2, the 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. For example, 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. According to 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. According to an 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 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.

According to an 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. 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.

According to an embodiment, 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. According to 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 flowchart 300 illustrating a driving method of an electronic device 101 according to an embodiment.

In operation 310, the electronic device 101 according to an embodiment may move a display location of one or more pixel data corresponding to an image associated with an application by a specified distance by using a display driver IC 230. A display 210 may include an active area (A/A) displaying an image. An image associated with at least one application may be displayed on the active area of the display 210. The image associated with the application may display information (e.g., a running screen) associated with a running or operation state of the corresponding application. When the application operates according to an input of a user or over the flow of time, the image associated with the application may display the changed state of the application and information to be indicated by the application. When a plurality of applications are running, the image associated with the application may be a running screen of the application, which is being input by the user, or an operation screen of an activated application.

In an embodiment, the image may be displayed using one or more pixels. One or more pixels arranged on the display 210 may operate based on pixel data. The display 210 may display an image having a specified luminance or a specified color based on pixel data. For example, the display 210 may receive pixel data displaying the image associated with the application and may display the image corresponding to the received pixel data.

In an embodiment, the display driver IC 230 may change a display location of one or more pixel data based on a specified rule on the active area. For example, the display driver IC 230 may change a location of the image at a specified time interval on the active area.

In an embodiment, the location of the image may move from any point by a specified distance. The any point may be set to coordinates. The any point may be represented as a distinguishing point on the display 210. For example, the location of the image may set a top-left vertex of the running screen to a reference point to represent the top-left vertex as origin coordinates. The top-left vertex may be located at a first point before moving and may move by a specified distance to move to a second point. The specified distance may be a length required to prevent degradation generated when the image is maintained for a long time. For example, the specified length may correspond to a length where a number of pixels to the point of being invisible to a user are arranged.

In an embodiment, the display driver IC 230 may specify a length in which any area moves. The display driver IC 230 may analyze content making up an image displayed on the display 210. For example, the display driver IC 230 may analyze parameters such as a luminance or a color of the content. The display driver IC 230 may analyze a degradation degree generated as the display 210 displays the content. The display driver IC 230 may specify a distance moved according to the degradation degree generated by the content. The display driver IC 230 may specify a distance where each area moves depending on content displayed on any area of the display 210.

In operation 320, the electronic device 101 according to an embodiment may scale up a first portion of the image by a specified range based on the specified distance. A processor 120 of the electronic device 101 may scale up at least a portion of a portion where the image is displayed to fill a portion changed to an empty space because the image is not displayed on the display 210 as the display location of the one or more pixel data moves by the specified distance. For example, the processor 120 may increase an area of a portion adjacent to the portion changed to the empty space. The processor 120 may scale up the portion adjacent to the portion changed to the empty space in the image to fill the empty space.

In operation 330, the electronic device 101 according to an embodiment may scale down a second portion of the image by the specified range based on the specified distance. The processor 120 of the electronic device 101 may scale down at least a portion of the portion where the image is displayed to prevent a portion, departing from the display 210, where the image is cropped, as the display location of the one or more pixel data moves by the specified distance. For example, the processor 120 may decrease an area of a portion adjacent to the portion departing from the display 210 in the image. The processor 120 may scale down the portion adjacent to the portion departing from the display 210 in the image such that the image is disposed in the display 210 without the cropped portion.

In operation 340, the electronic device 101 according to an embodiment may display the image on the active area based on the scaled-up first portion and the scaled-down second portion. Although the image having the scaled-up first portion and the scaled-down second portion moves by the specified length, it may be output without the empty portion or the cropped portion on the display 210.

FIG. 4 is a drawing illustrating that an electronic device 101 moves an image 410 of an application according to an embodiment.

In an embodiment, a display driver IC 230 of an electronic device 101 may display an image 410 associated with an application on a display 210. The display driver IC 230 may move a display location of one or more pixel data corresponding to the image 410 to prevent degradation of the display 210. The display driver IC 230 may move the display location of the pixel data by a specified distance at a specified time interval. The display driver IC 230 may move the display location of the pixel data in a predefined direction.

In an embodiment, after moving the display location of the pixel data, the moved image 420 may be displayed on the display 210. Comparing the same content with respect to the locations displaying the same content, the moved image 420 may have a distance difference with the image 410 by the specified distance. The moved image 420 may include a first portion 421 and a second portion 422.

In an embodiment, the first portion 421 may be disposed on an edge area of the moved image 420. The first portion 421 may be disposed at an opposite side of the direction where the display location of the pixel data moves. For example, when the display location of the pixel data moves to the bottom right to display the moved image 420, the first portion 421 may be disposed on the top left of the moved image 420.

In an embodiment, the second portion 422 may be disposed on an edge area of the moved running screen 420. The second portion 422 may be disposed in the direction where the display location of the pixel data moves. For example, when the display location of the pixel data moves to the bottom right to display the moved image 420, the first portion 421 may be disposed on the bottom right of the moved image 420.

In an embodiment, the image 410 before moving may display content making up the image on the active area which is an area displayed by the solid line. The moved image 420 may display content making up the image on a content area of the image, which is an area displayed by the dotted line.

FIG. 5A is a drawing 500 illustrating that an electronic device 101 scales up an image according to an embodiment.

In an embodiment, a processor 120 of the electronic device 101 may scale up at least a portion of the image. The processor 120 may identify an empty space where the image is not displayed on an active area of a display 210. The processor 120 may scale up a first portion 510 of the image to remove the empty space of the display 210. The processor 120 may set a portion scaled up in the image to the first portion 510. For example, when an opposite side of the direction where the display location of the pixel data moves is scaled up, the processor 120 may set at least a portion of the opposite side of the direction where the display location of the pixel data moves to the first portion 510.

In an embodiment, up-scale may be performed in the first portion 510. When the up-scale is applied, an area of a portion displaying the same content may be scaled up such that distortion is not visible to a user. Pixel copy or pixel interpolation may be applied to apply the up-scale. When the pixel copy is applied, a pixel of an empty space may operate to the same as each of pixels displaying an image of an area adjacent to the empty space of the display 210. When the pixel interpolation is applied, pixels displaying the image of the area adjacent to the empty space of the display 210 may be set to a group for every a specified number of pixels. The processor 120 may set an average value of the pixels of the corresponding group to be displayed by a next pixel. In such a manner, the empty space of the display 210 may be filled while increasing the number of pixels displaying the same content on the first portion 510.

In an embodiment, the processor 120 of the electronic device 101 may scale up the first portion 510 to fill an empty portion on the active area of the display 210 as the display location of the pixel data moves. The processor 120 may scale up the first portion 510 to a border of the active area. For example, the processor 120 may be configured to scale up and display content displayed on a content area of the image displayed on the first portion 510 by the dotted line when not scaled up the border of the active area.

FIG. 5B is a drawing illustrating that an electronic device 101 scales down an image according to an embodiment.

In an embodiment, a processor 120 of the electronic device 101 may scale down at least a portion of the image. The processor 120 may identify a portion where the image departs from the active area of the display 210 to be cropped. The processor 120 may scale down a second portion 520 of the image to remove the portion where the image is cropped. The processor 120 may set a portion scaled down in the image to the second portion 520. For example, when the direction where the display location of the pixel data moves is scaled down, the processor 120 may set at least a portion of the direction where the display location of the pixel data to the second portion 520.

In an embodiment, down-scale may be performed in the second portion 520. When the down-scale is applied, an area of a portion displaying the same content may be scaled down such that distortion is not visible to a user. Pixel truncation may be applied to apply the down-scale. When the pixel truncation is applied, pixels displaying an image of an area adjacent to an empty space of the display 210 may be set to a group for every a specified number of pixels. The processor 120 may configured to delete any one of pixels of the corresponding group. In such a manner, the image departing from the display 210 may be scaled down while reducing the number of pixels displaying the same content on the second portion 520.

In an embodiment, the processor 120 of the electronic device 101 may scale down the second portion 520 to remove a portion cropped on the active area of the display 210 as the display location of the pixel data moves. The processor 120 may scale down the first portion 520 to a border of the active area. For example, the processor 120 may configured to scale down and display content displayed on a content area of the image displayed on the second portion 520 by the dotted line when not scaled down to the border of the active area.

FIG. 6 is a drawing 600 illustrating that an electronic device 101 scales up and crops content making up all of an image according to an embodiment.

In an embodiment, a display driver IC 230 may move content of the image in the direction of bottom right. The content of the image may move to the bottom right compared with an active area. An empty area where pixel data does not display content may occur on a top-left area of the active area. At least a portion of content to be displayed by pixel data may move on to outside the active area on a bottom-right area of the active area and may not be displayed on the active area to be cropped.

In an embodiment, the processor 120 may set at least a portion of an opposite side of the direction where the display location of the pixel data moves to a first portion 610 and may set at least a portion of the direction where the display location of the pixel data moves to a second portion 620. For example, the processor 120 may set a top-left area, which is an opposite side of the direction where the content of the image moves, to the first portion 610 and may set a bottom-right area, which is the direction where the content of the image moves, to the second portion 620.

In an embodiment, the processor 120 of the electronic device 101 may apply up-scale to the first portion 610 of the content of the image to scale up the first portion 610. The processor 120 may scale up an empty portion to be filled on the active area. The processor 120 may scale up the content of the image displayed on the first portion 610 to a border of the active area. For example, the processor 120 may configured to scale up and display content displayed on a content area of the image displayed on the first portion 610 by the dotted line when not scaled up to the border of the active area.

In an embodiment, the processor 120 of the electronic device 101 may be configured to maintain the second portion 620 of the content of the image without change without scaling up or down the second portion 620. The processor 120 may display the content of the image displayed on the second portion 620 in the same manner as that before moving. The processor 120 may be configured to crop a portion moving on outside of the active area in the content of the image. The processor 120 may fail to display the portion moving on outside of the active area in the content of the image. For example, when it is determined to display content where it does not matter when a partial area is cropped, for example, when the same color or the same pattern is repeated on the second portion 620, the processor 120 may maintain content, displayed on a content area of the image displayed on the second portion 620 by the dotted line when not scaled down, in a state where it is outside the active area, to fail to display the content.

FIG. 7 is a drawing 700 illustrating that an electronic device scales down content making up a portion of an image according to an embodiment.

In an embodiment, a display driver IC 230 may move content making up a portion of the image. In this case, only some content of the image may move from the active area, and the other content may maintain its fixed location on the active area. The display driver IC 230 may move only content where it is easy to generate degradation on the display 210 from the active area. For example, the display driver IC 230 may move only a location of specific content, such as a button maintaining a fixed shape and color, in a state where a location of background image content displaying a background changed in real time in the image is fixed.

In an embodiment, the display driver IC 230 may move content making up a portion of the image to outside the active area. At least a portion of content to be displayed by pixel data may move on to outside the active area on a top-left area of the active area and may not be displayed on the active area to be cropped.

In an embodiment, the processor 120 may set at least a portion of an opposite side of the direction where a display location of pixel data moves to a first portion 710 and may set at least a portion of the direction where the display location of the pixel data moves to a second portion 720. For example, the processor 120 may set a bottom-right portion of a content area of the image to the first portion 710 and may set a top-left area of the content area of the image to the second portion 720.

In an embodiment, the processor 120 of an electronic device 101 may be configured to maintain the first portion 710 of the content of the image without change without scaling up or down the first portion 710. The processor 120 may display the content of the image displayed on the first portion 710 in the same manner as that before moving.

In an embodiment, the processor 120 may apply down-scale to the second portion 720 of the content of the image to scale down the second portion 720. The processor 120 may scale down the second portion 720 such that a cropped portion does not occur in the content of the image. The processor 120 may scale down the second portion 720 to remove a portion cropped on the active area as the display location of the pixel data moves. The processor 120 may scale down the second portion 720 to a border of the active area. For example, the processor 120 may be configured to scale down and display content displayed on a content area of the image displayed on the second portion 720 by the dotted line when not scaled down to the border of the active area.

FIG. 8 is a drawing illustrating that an electronic device scales up content making up a portion of an image according to an embodiment.

In an embodiment, a display driver IC 230 may move content making up a portion of the image to inside an active area. An empty area where pixel data does not display content may occur on a top-left area of the display area.

In an embodiment, a processor 120 may set at least a portion of an opposite side of the direction where a display location of pixel data moves to a first portion 810 and may set at least a portion of the direction where the display location of the pixel data moves to a second portion 820. For example, the processor 120 may set a top-left portion of a content area of the image to the first portion 810 and may set a bottom-right area of the content area of the image to the second portion 820.

In an embodiment, the processor 120 may apply up-scale to the first portion 810 of the content of the image to scale up the first portion 810. The processor 120 may scale up the first portion 810 such that a cropped portion does not occur on the active area. The processor 120 may scale up the first portion 810 such that the empty area according to movement of the display location of the pixel data does not occur on the active area. The processor 120 may scale up the first portion 810 to a border of the active area. For example, the processor 120 may be configured to scale up and display content displayed on a content area of the image displayed on the first portion 810 by the dotted line when not scaled down to the border of the active area.

In an embodiment, the processor 120 of an electronic device 101 may be configured to maintain the second portion 820 of the content of the image without change without scaling up or down the second portion 820. The processor 120 may display the content of the image displayed on the second portion 820 in the same manner as that before moving.

FIG. 9 is a drawing 900 illustrating that an electronic device 101 scales up and down an image according to another embodiment.

In an embodiment, a processor 120 of the electronic device 101 may scale up a first portion 910 of the image to remove an empty space of an active area of a display 210. To scale up an image to an opposite side of the direction where a display location of pixel data moves, the processor 120 may set at least a portion of a central portion of the image to a first portion 910. For example, when the display location of the pixel data moves to the right, the processor 120 may apply up-scale to the first portion 910 set to the central portion to scale up the image to the left. The processor 120 may scale up the image to a border of the active area of the display 210.

In an embodiment, the processor 120 of the electronic device 101 may scale down a second portion 920 of the image to remove a cropped space of the image. To scale down the image in the direction where the display location of the pixel data moves, the processor 120 may set an edge portion disposed in the direction to the second portion 920. For example, when the display location of the pixel data moves to the right, the processor 120 may specify a right edge area to the second area 920. The processor 120 may apply down-scale to the second portion 920 to scale down the image. The processor 120 may scale down the image to a border of the active area of the display 210.

FIG. 10 is a drawing 1000 illustrating that an electronic device 101 scales up and down an image according to another embodiment.

In an embodiment, a processor 120 of the electronic device 101 may scale up a first portion 1010 of the image to remove an empty space of an active area of a display 210. To scale up the image to an opposite side of the direction where a display location of pixel data moves, the processor 120 may set an edge portion disposed at the opposite side of the direction to the first portion 1010. For example, when the display location of the pixel data moves to the bottom, the processor 120 may specify a top edge area to the first portion 1010. The processor 120 may apply up-scale to the first portion 1010 to scale up the image to the top. The processor 120 may scale up the image to a border of the active area of the display 210.

In an embodiment, the processor 120 of the electronic device 101 may scale down a second portion 1020 of the image to remove a cropped portion of the image. To scale down the image in the direction where the display location of the pixel data moves, the processor 120 may set at least a portion of a central portion to the second portion 1020. For example, when the display location of the pixel data moves to the bottom, the processor 120 may apply down-scale to the second portion 1020 to scale down the image. The processor 120 may scale down the image to a border of the active area of the display 210.

FIG. 11 is a drawing 1100 illustrating that an electronic device 101 displays an image in three dimensions according to an embodiment.

In an embodiment, a display driver IC 230 of the electronic device 101 may be configured to, when a display location of pixel data moves, represent an edge portion 1110 adjacent to a border of a display 210 in the image in three dimensions. When the display location of the pixel data moves, the display driver IC 230 may display content in three dimensions by assigning a three-dimensional effect at the same time as changing an area of the content displayed on the edge portion 1110 of the image.

In an embodiment, the display driver IC 230 may be configured to perform stereoscopic effect processing, such as a ripple effect or a three-dimensional effect, on the edge portion 1110 such that a user views a running screen like a three-dimensional screen. The display driver IC 230 may be configured to change data in software such that the edge portion 1110 of the image is visible like a three-dimensional screen, or may be configured such that the edge portion 1110 of the image is visible like the three-dimensional screen using a physical structure of the electronic device 101. For example, the display driver IC 230 may be configured to, when the edge portion 1110 of the display 210 is formed as a curved surface unlike a central portion 1120, assign a sense of flexion while changing an area of content when a display location of pixel data moves such that the user views the image like the three-dimensional screen.

FIG. 12 is a drawing 1200 illustrating that an electronic device 101 moves an image having making portions 1230 and 1240 according to an embodiment.

In an embodiment, a display driver IC 230 of the electronic device 101 may move an image. For example, the display driver IC 230 may move the image by a specified distance with respect to a predefined point 1210 which is one of vertices of the image to move the predetermined point 1210 to a moved point 1220.

In an embodiment, the display driver IC 230 may generate the masking portion 1230 hiding an image of an edge portion adjacent a border of the display 210 in the image. The masking portion 1230 may be disposed to surround an active area in a bezel disposed on a border of the display 210. The masking portion 1230 may be disposed to surround vertices and corners including the predefined point 1210. Pixels displaying the masking portion 1230 may operate with a predefined gray scale (e.g., a black gray scale) such that the image is not visible.

In an embodiment, when the location of the image moves, the masking portion 1230 may move by a specified distance in the same direction as the direction where a display location of pixel data moves. When the display location of the pixel data moves, a moved masking portion 1240 may be disposed to surround vertices and corners including the moved point 1220 with respect to the moved point 1220. For another example, when the location of the image moves, the masking portion 1230 may be scaled up by the specified distance in the same direction as the direction where the display location of the pixel data moves. In this case, the masking portion 1230 may increase in area to include all from an originally occupied area to a portion 1240 surrounding vertices and corners including the moved point 1220 with respect to the moved point 1220.

FIG. 13 is a drawing 1300 illustrating that an electronic device 101 moves a location of an image according to another embodiment.

In an embodiment, a display driver IC 230 of the electronic device 101 may change movement strength and a jumping area of content of the image depending on a driving condition of a display 210. In the disclosure, the movement strength of the content of the image may be referred to as a time interval moving a location of the image. Furthermore, in the disclosure, the jump area of the content of the image may be referred to as a specified distance moving the location of the image. The more the risk that degradation will occur increases on the display 210, the more the display driver IC 230 may increase the movement strength and the jump area of the content. The risk that the degradation will occur may be calculated based on a luminance of the image, a temperature of the electronic device 101, or color strength of the image.

In an embodiment, the display driver IC 230 of the electronic device 101 may move a location of the image at a specified time interval. The specified time interval may be set according to a luminance of the image, a temperature of the electronic device 101, or color strength of the image. For example, when the luminance of the image increases to a specified luminance or more (e.g., a standard luminance of 183 nit or more), the display driver IC 230 may reduce a period when the image moves (e.g., reduce 60 seconds to 40 seconds). As another example, when the luminance of the image decreases to another specified luminance or less (e.g., low luminance of 60 nit or less), the display driver IC 230 may increase the period when the image moves (e.g., increase 60 seconds to 90 seconds).

In an embodiment, the display driver IC 230 of the electronic device 101 may move a location of the image by a specified distance. The specified distance may be proportional to a degree of risk that degradation will occur. For example, the specified distance may be set according to a luminance of the image, a temperature of the electronic device 101, or color strength of the image.

In an embodiment, the display driver IC 230 of the electronic device 101 may move an image 1310 by a specified distance and may display moved images 1320 and 1330. For example, when the luminance of the image increases to a specified luminance or more, the display driver IC 230 may increase a distance where the image moves (e.g., increase a width of two pixels to a width of three pixels) and may display the moved image 1330. For another example, when the luminance of the image decreases to another specified luminance or less, the display driver IC 230 may decrease a distance where the image moves (e.g., decrease a width of two pixels to a width of one pixel) and may display the moved image 1320.

FIG. 14 is a drawing 1400 illustrating that an electronic device 101 moves a location of an image according to another embodiment.

In an embodiment, a display driver IC 230 of the electronic device 101 may divide an image into a plurality of areas including a first area 1410 and a second area 1420. The first area 1410 and the second area 1420 may be arranged at different locations of the image. The first area 1410 and the second area 1420 may display different content. The first area 1410 and the second area 1420 may have different areas, luminance, temperature, color strength, or the amount of change of displayed content. The first area 1410 and the second area 1420 may have different degrees to which degradation occurs.

In an embodiment, a processor 120 of the electronic device 101 may move a location of the first area 1410 by a first distance and may move a location of the second area 1420 by a second distance. After the first area 1410 moves by the first distance, content displayed on the first area 1410 may be displayed on a moved first area 1430. After the second area moves by the second distance, content displayed on the second area 1420 may be displayed on a moved second area 1440. The first distance or the second distance may be set based on conditions, such as an area of the first area 1410 or the second area 1420, an area around the first area 1410 or the second area 1420, or a risk of degradation in the first area 1410 or the second area 1420. For example, when the area of the first area 1410 is small and when displaying content of low luminance, the processor 120 may set the first distance to be shorter than the second distance.

In an embodiment, the processor 120 of the electronic device 101 may be configured to display the image on an active area based on the moved first area 1430 and the moved second area 1440. The processor 120 may move the first area 1410 or the second area 1420 to change the location to the moved first area 1430 or the moved second area 1440 and may display the image. The processor 120 may scale up or down an area except for the first area 1410 or the second area 1420 to prevent an empty space or a cropped portion capable of occurring due to the movement and may display the image on the active area.

FIG. 15 is a block diagram 1500 illustrating that an electronic device 101 corrects touch coordinates as moving coordinates of an image according to an embodiment. In FIG. 15, an AP 1510 may be substantially the same as a processor 120, and a DDI 1520 may be substantially the same as a display driver IC 230. Furthermore, in FIG. 12, a display 1530 may be the same component as a display 210, and a touch IC 1540 may be the same component as a touch sensor IC 253. Furthermore, in FIG. 15, a touch panel 1550 may be disposed on the display 1530 and may include a touch sensor 251 to detect a touch of a user.

In an embodiment, the AP 1510 may control the DDI 1520 and may deliver pixel data display location coordinates capable of displaying an image of an application to the DDI 1520.

In an embodiment, the DDI 1520 may display an image on the display 1530 using image data obtained from the AP 1510. When displaying the image, the DDI 1520 may move pixel data display location coordinates on the display 1530 to prevent degradation. For example, the DDI 1520 may move the image at a specified time interval by a specified distance. In this case, vertices of the image may move by the amount of change in the specified coordinates.

In an embodiment, the DDI 1520 may notify the AP 1510 and the touch IC 1540 that the coordinates of the image move. The DDI 1520 may deliver information associated with a time when the coordinates of the image move and the amount of change in the coordinates to the AP 1510 and the touch IC 1540.

In an embodiment, the touch IC 1540 may receive information providing the notification that pixel data display location coordinates move from the DDI 1520. When receiving the information providing the notification that the pixel data display location coordinates move, because the image moves, the touch IC 1540 may detect that touch coordinates, which are a location where a user touches content, should be corrected to correspond to the moved image. The touch IC 1540 may request the AP 1510 to correct the touch coordinates.

In an embodiment, the AP 1510 may receive the information providing the notification that the pixel data display location coordinates move from the DDI 1520 and may receive a request to correct the touch coordinates from the touch IC 1540. The AP 1510 may correct the touch coordinates based on the amount of change in the pixel data display location coordinates. For example, the AP 1510 may move touch coordinates to correspond to the amount of change in the pixel data display location coordinates and apply the same touch coordinates to the same content.

In an embodiment, the AP 1510 may correct and deliver the touch coordinates to the touch IC 1540. The AP 1510 may correspond and input the corrected touch coordinates one to one to the touch IC 1540.

In an embodiment, the touch IC 1540 may notify the touch panel 1550 that the touch coordinates move. The touch IC 1540 may be configured to detect a touch of the user in response to the touch coordinates moved by the touch sensor 251 of the touch panel 1550.
