The present application claims priority under 35 U.S.C. §119 and 35 U.S.C. §365 to Korean Patent Application No. 10-2015-0176366 (filed on Dec. 10, 2015), which is hereby incorporated by reference in its entirety.
Field of the Invention
The present disclosure relates to a flexible display device.
Discussion of the Related Art
With the development of a display technology, researches have been conducted to develop flexible display devices that can be rolled or can be stretched in at least one direction if being used. Such display devices can be variously changed in shape, and thus may satisfy both the requirement of a large-size screen at a stage of display use and the requirement of a compact display size for display portability.
In addition, a flexible display device may be deformed into not only a predetermined shape but also various shapes depending on a user's intention or an environment in which the display device is used. Therefore, if a display area of the display device is fixed, a user may feel a sense of inconvenience.
Furthermore, if the display area of the display device is fixed, the user is required to provide an additional input for capturing a screen or push a favorites button to register or store displayed information in a favorites list. Moreover, since a list of recently used applications simply arranges the recently used applications according to time of use thereof, it may be difficult for the user to directly call an execution window of an application stored by the user.
Embodiments provide a flexible display device capable of being extended or reduced by a simple operation according to a request of a user.
Embodiments also provide a flexible display device capable of efficiently storing information displayed on a display and easily calling the information.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, the present invention provides in one aspect a flexible display device including a memory; a display including an extendable and reducible screen; a sensor configured to detect a size of the screen; and a controller configured to display information on the extended screen, and store the information in the memory in response to the size of the screen being reduced while the information is selected. The present invention also provides a corresponding method of controlling the flexible display device.

The flexible display device 200 according to an embodiment is a next-generation display device that is not only bendable but also stretchable and can be implemented in various and new environments, compared to typical display devices implemented using a rigid material such as glass, silicon, or the like.
In one embodiment, the flexible display device 200 can be a stretchable display device that is stretched if being pulled and recovers its original form if being released. If a certain period of time elapses while the flexible display device is being pulled and stretched, the flexible display device can be fixed in a stretched state. If a force is applied to the flexible display device, the flexible display device can contract to recover its original form.
In another embodiment, the flexible display device 200 can be a rollable display device that can be rolled or unrolled like paper. Referring to
In one embodiment, the sensor 210 can include at least one pressure sensor. The at least one pressure sensor can be disposed at the display 250. When the sensor 210 includes at least one pressure sensor, each pressure sensor 211 can detect a change in resistance or capacitance between both ends of an area to which a pressure (or force) is applied as illustrated in
In another embodiment, the sensor 210 can include the plurality of acceleration sensors 213-1 to 213-4 as illustrated in
The acceleration sensor serves to detect an intensity of impact or an acceleration of an object. A motion state of the display 250 can be accurately detected using the acceleration sensor. The acceleration sensor can sense the acceleration of the display 250 in three axial (x-axis, y-axis, z-axis) directions perpendicular to each other. The controller 290 can obtain a moving speed using a tri-axial acceleration measured by the acceleration sensor. The controller 290 can obtain a tri-axially extended distance of the display 250 using the obtained moving speed. The controller 290 can obtain the strength and the direction of the force applied to the display 250, using the moving speed and distance obtained using the acceleration sensor. The controller 290 can extend the display 250 according to the direction and the strength of the force.
In another embodiment, the sensor 210 can include a plurality of hall sensors. The plurality of hall sensors can be arranged inside the display 250 or on the display 250. When the sensor 210 includes the plurality of hall sensors, the controller 290 can extend or reduce the display 250 using voltage sensed by the hall sensors.
When the sensor 210 includes the hall sensors, an embodiment in which extension or reduction of the display 250 is detected using the hall sensors will be described with reference to
The display 250 can include an organic light-emitting diode (OLED). The memory 270 can store a strength of a force applied to the display 250 and an extension degree or a reduction degree of the display 250 which corresponds to the strength of the force. The extension degree of the display 250 can indicate an extended length of the display 250, and the reduction degree of the display 250 can indicate a reduced length of the display 250.
The controller 290 can detect extension or reduction of the display 250 via the sensor 210. The extension of the display 250 can indicate that a size of a screen able to be displayed by the display 250 is increased, and the reduction of the display 250 can indicate that the size of the screen able to be displayed by the display 250 is decreased. The controller 290 can change a graphic or an image displayed on the screen according to the increase or decrease in the size of the screen of the display 250. Furthermore, the controller 290 can control overall operation of the flexible display device 200. Operation of the controller 290 will be described in more detail later.
Referring to
The upper case 240 and the lower case 260 can cover the intermediate case 220 at an upper side and a lower side thereof. The upper case 240 and the lower case 260 may not expose various components arranged inside the intermediate case 220. A recess part 246 can be formed in the upper case 240, wherein the recess part 246 can be recessed towards the inside of the upper case 240 so as to have a planar shape. At least one of a camera 241 or a sound output unit 242 can be disposed in the recess part 246.
The first holder 223 (see
The display 250 can be rolled in towards the inner side of the intermediate case 220, or can be rolled out of the intermediate case 220. That is, the display 250 can be wound, rolled or coiled into the inner side of the intermediate case 220, or can be unwound, unrolled or uncoiled out of the intermediate case 220.
When the display 250 is not deformed (e.g., a state of having an infinite radius of curvature, hereinafter referred to as the first operation state), a region displayed by the display 250 can be a plane. When the display 250 is deformed by an external force in the first operation state (e.g., a state of having a finite radius of curvature, hereinafter referred to as the second operation state), a region displayed by the display 250 can be a curved surface. As illustrated in the drawings, information displayed in the second operation state can be time information output to the curved surface. Such time information can be implemented by individually controlling light emission of sub-pixels arranged in a matrix.
In the first operation state, the display 250 may not be flat but curved (e.g., vertically or horizontally curved). In this instance, if an external force is applied to the display 250, the display 250 can be deformed to be flat (or less curved) or more curved.
The display 250 can be combined with a touch sensor to implement a flexible touch screen. If the flexible touch screen is touched, a controller 290 can perform control corresponding to the touch input. The flexible touch screen can detect a touch input not only in the first operation state but also in the second operation state.
The rollable display device 200-2 according to an embodiment can be provided with a deformation detecting unit for detecting deformation of the display 250. The deformation detecting unit can be included in the sensor 210 (see
The deformation detecting unit can be provided to the display 250 or the intermediate case 220 so as to detect information on deformation of the display 250. Here, the information on deformation can include a deformation direction, a deformation degree, a deformation portion, or a deformation time of the display 250 or an acceleration of recovery of the display 250 deformed, or can additionally include various information detectable due to warpage of the display 250.
Furthermore, the controller 290 can change information displayed on the display 250 or can generate a control signal for controlling a function of the rollable display device 200-2, based on the information on deformation of the display 250 detected by the deformation detecting unit.
In an embodiment, the first operation state of the rollable display device 200-2 represents an inactive state in which a minimum display region is exposed to the outside so that basic information alone is displayed. The second operation state of the rollable display device 200-2 represents an active state in which the display 250 is extended. Extending of the display 250 can indicate that a screen displayed by the display 250 is extended.
This extending includes gradational extending. A display region of the rollable display device 200-2, which is extended or reduced by rolling the display 250, can be implemented at one time at the moment of the extending or reducing, or the display region can be gradually extended or reduced. Therefore, hereinafter all states excepting the first operation state can be regarded as the second operation state, and the second operation state can be classified into a plurality of stages according to a degree of extension.
As illustrated in
The controller 290 (see
Furthermore, if the display 250 is separated from an outer circumferential surface of an inner case 238, the controller 290 can turn on a separated part of the display 250 and can turn off a non-separated part of the display 250. The controller 290 can detect that the display 250 is separated from the outer circumferential surface of the inner case 238 using a length sensor 211 disposed in an inner circumferential surface of the inner case 238, so as to turn on the separated part of the display 250 and turn off the non-separated part of the display 250.
Referring to
The inner case 238 can be shaped like a roller, can be rollable, and can serve to wind or unwind the display 250. The inner case 238 is axially connected to the intermediate case 220 so as to be rotatable. The length sensor 211 can sense a wound length or an unwound length of the display 250. The length sensor 211 can include a magnetic member. The length sensor 211 can include at least one hall sensor. The length sensor 211 will be described later in more detail.
The rotation amount sensor 213 can sense the number of turns of the display 250 wound on the inner case 238. That is, the rotation amount sensor 213 can sense the number of turns of the display 250 wound on the inner case 238 as the display 250 is rolled. The rotation amount sensor 213 can include a magnetic member. The rotation amount sensor 213 can include at least one hall sensor. The rotation amount sensor 213 will be described later in more detail.
A plurality of electronic circuit components for operating the rollable display device 200-2 can be mounted on each circuit board 280. The flexible circuit board 283 can connect electronic circuit components mounted on the inner case 238 to the display 250. The electronic circuit component can include at least one of the sensor 210, the memory 270, or the controller 290 illustrated in
The inner case 238 can be rotated by magnetism between the length sensor 211 and rolling sensors 234 spaced apart from each other under the display 250. The rolling sensor 234 can include a magnetic member, and can include at least one hall sensor. The display 250 can be rotated together with the inner case 238 while being rolled on the inner case 238 by the magnetism. In more detail, the display 250 can be rolled by attraction between the rolling sensor 234 and the length sensor 211. For example, when the length sensor 211 includes an N-pole magnetic member and the rolling sensor 234 includes an S-pole magnetic member, they attract each other. A position of the length sensor 211 can be fixed.
The rolling sensor 234 is attracted towards the length sensor 211 while moving linearly, and the rolling sensors 234 spaced apart from each other are continually introduced into the intermediate case 220. Since the rolling sensor 234 that has been already introduced and the length sensor 211 continuously attract each other, the rolling sensor 234 newly introduced and the length sensor 211 maintain a balance in terms of attraction so that the rolling sensors 234 are rotated around the length sensors 211. By virtue of this mechanism, the display 250 is wound while being rolled.
A sheet 222 provided with the rolling sensor 234 can be disposed on a lower surface of the display 250. The sheet 222 can be included in the display 250, or can be present independently from the display 250. The sheet 222 can be flexible. For example, the sheet 222 can be silicone or Thermoplastic Poly Urethane (TPU). The sheet 222 can be bonded to the lower surface of the display 250 in the form of a sheet frame, can sequentially fix the rolling sensors 234, and can be formed through bonding, tape or insert molding.
Furthermore, the sheet 222 can be formed of a material that is flexible, has excellent elasticity and elongation, and enables maintenance of a small thickness of the sheet 222. This is intended to allow the rolling sensors 234 to have the same magnetic pole so that the display 250 is spread flat by repulsion. That is, the rolling sensors 234 having the same magnetic pole repel each other by a repulsive force so that the display 250 is spread flat.
The length sensor 211 can sense magnetism between the rolling sensor 234 and the length sensor 211 to calculate the wound length or the unwound length of the display 250. The rotation amount sensor 213 can sense the number of turns of the display 250 wound on the outer circumferential surface of the inner case 238. This will be described later in more detail with reference to
Referring to
The arrows of
As described above, the first to fourth hall sensors H1 to H4 provide information for measuring a length of the display 250 wound along the outer circumferential surface of the inner case 238. The controller 290 can detect a sensor that lastly senses the rolling sensor 234 if the display 250 is wound or unwound. Accordingly, the controller 290 can calculate the wound length or the unwound length of the display 250. This is the same for the case where the display 250 is wound on the inner case 238 by multiple turns.
When the display 250 is wound on the outer circumferential surface 238 in two or more layers, magnetism is changed in a radial direction of the inner case 238. Therefore, if a hall sensor for sensing the change is provided, the wound length of the display 250 can be measured more accurately.
For example, as illustrated in
In more detail, in the second operation state (i.e., the state illustrated in
A length of the display 250 wound thereafter can be calculated using the first to fourth hall sensors H1 to 114, and, if the display 250 is stacked in three layers in a radial direction in which the fifth to seventh hall sensors H5 to H7 are arranged, the magnetism change is sensed by the fifth to seventh hall sensors H5 to H7. As described above, the controller 290 can calculate the length of the display 250 wound on the outer circumferential surface of the inner case 238 using the first to fourth hall sensors H1 to H4, and can calculate the number of turns of the display 250 wound on the outer circumferential surface of the inner case 283 using the fifth to seventh hall sensors H5 to H7.
According to another embodiment, the rollable display device 200-2 can be additionally provided with the upper case 240, the intermediate case 220, and the lower case 260 at another end portion of the display 250. The elements described above with reference to

Hereinafter, the above-described elements are described in detail with reference to
The mobile communication module 112 can transmit and receive wireless signals to and from at least one selected from a base station, an external terminal, and a server on a mobile communication network constructed according to technical standards or communication schemes for the mobile communication (e.g., Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA 2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), and Long Term Evolution-Advanced (LTE-A) etc.).
The wireless signal can include a voice call signal, a video call signal, or various types of data according to transmission and reception of a text/multimedia message. The wireless internet module 113 refers to a module for a wireless internet connection, and can be embedded in or prepared outside the mobile terminal 100. The wireless internet module 113 is configured to transmit and receive a wireless signal over a communication network conforming with wireless internet technologies.
The wireless internet technologies include, for example, Wireless LAN (WLAN), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), and LTE-Advanced (LTE-A), and the wireless internet module 113 transmits and receives data according to at least one wireless internet technology within the range of including internet technology not described in the above.
From a viewpoint that an access to the wireless internet through WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, or LTE-A is conducted through a mobile communication network, the wireless internet module 113 conducting the access to the wireless internet through the mobile communication network can be understood as a kind of the mobile communication module 112.
The short range communication module 114 is for short range communication and can support the short range communication by using at least one selected from Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband UWB), ZigBee, Near Field Communication (NFC), Wi-Fi, Wi-Fi Direct, and Wireless Universal Serial Bus (Wireless USB) technologies. This short range communication module 114 can support, through a wireless area network, wireless communication between the mobile communication terminal 100 and a wireless communication system, between the mobile terminal 100 and another mobile terminal 100, or between the mobile terminal 100 and a network on which the other mobile terminal 100 or an external server is located. The wireless area network can be a wireless personal area network.
Here, the other mobile terminal 100 can be a wearable device (e.g., a smart watch, a smart glass, or an HMD) through which data is mutually exchangeable (or interworkable) with the mobile terminal 100 according to an embodiment. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. Furthermore, if the detected wearable device is authenticated to communicate with the mobile terminal 100, the controller 180 can transmit at least a part of data processed in the mobile terminal 100 to the wearable device through the short range communication module 114. Therefore, a user of the wearable device can use the data processed by the mobile terminal 100 through the wearable device. For example, if a call is received by the mobile terminal 100, the user can perform a phone call through the wearable device, or if a message is received by the mobile terminal 100, the user can check the received message through the wearable device.
The location information module 115 is for obtaining a location (or a current location) of the mobile terminal. As a representative example thereof, there is a global positioning system (GPS) module or a Wi-Fi module. For example, if adopting the GPS module, the mobile terminal can obtain a location of the mobile terminal by using a signal transmitted from a GPS satellite. In another example, if adopting the Wi-Fi module, the mobile terminal can obtain the location of the mobile terminal based on information on a wireless access point (AP) transmitting or receiving a wireless signal with the Wi-Fi module. If necessary, the location information module 115 can additionally or alternatively perform any one function among other modules in the wireless communication unit 110 in order to obtain data about the location of the mobile terminal. The location information module 115 is a module used for obtaining the location (or current location) of the mobile terminal, and is not limited to a module directly calculating or obtaining the location of the mobile terminal.
Next, the input unit 120 is for receiving image information (or an image signal), audio information (or an audio signal), data, or information input from the user. The mobile terminal 100 can include one or a plurality of cameras 121 for an input of image information. The camera 121 processes an image frame such as a still image or video obtained by an image sensor in a video call mode or an image capturing mode. The processed image frame can be displayed on the display 151 or stored in the memory 170. Furthermore, the plurality of cameras 121 prepared in the mobile terminal 100 can be arranged to form a matrix structure, and, through the cameras 121 forming this matrix structure, a plurality of pieces of information on images having different angles or different focuses can be input to the mobile terminal 100. In addition, the plurality of cameras 121 can be arranged in a stereo structure to obtain left and right images for realizing a stereoscopic image.
The microphone 122 can process an external sound signal as electrical voice data. The processed voice data can be variously used according to a function (or an application program) being performed in the mobile terminal 100. Furthermore, various noise removal algorithms can be implemented for removing noise generated in a process for receiving the external sound signal.
The user input unit 123 is for receiving information from the user. If information is input through the user input unit 123, the controller 180 can control an operation of the mobile terminal 100 in correspondence to the input information. This user input unit 123 can include a mechanical input unit (or mechanical key, for example, buttons positioned on the front and rear surfaces or on the side surfaces, a dome switch, a jog wheel, or a jog switch, etc.) and a touch type input unit. As an example, the touch type input unit can be configured with a virtual key displayed on a touch screen through a software processing, a soft key, or a visual key, or a touch key disposed on a portion other than the touch screen. In addition, the virtual key or the visual key is possibly displayed on the touch screen in various types and, for example, can be configured with graphics, texts, icons, videos, or a combination thereof.
Furthermore, the sensor 140 can sense at least one of environmental information surrounding the mobile terminal 100 and user information, and generate a sensing signal corresponding to the sensed information. The controller 180 can control driving or operations of the mobile terminal 100, or perform data processing, a function, or an operation related to an application program installed in the mobile terminal 100, based on the sensing signal. Hereinafter, representative sensors among various sensors that can be included in the sensor 140 are described in detail.
Firstly, the proximity sensor 141 refers to a sensor detecting presence of an object accessing or around a predetermined detecting surface by using an electromagnetic force or an infrared ray without a mechanical contact. This proximity sensor 141 can be disposed in an internal area of the mobile terminal surrounded by the above-described touch screen or around the touch screen.
As an example of the proximity sensor 141, there is a transmissive optoelectronic sensor, a diffuse optoelectronic sensor, a high frequency oscillating proximity sensor, a capacitive proximity sensor, an inductive proximity sensor, or an infrared proximity sensor. If the touch screen is capacitive type, the proximity sensor 141 can be configured to detect an access of an object having conductivity by a change of an electric field according to the access of the object. In this instance, the touch screen (or a touch sensor) itself can be classified into a proximity sensor.
Moreover, for convenience of explanation, a behavior that an object is in proximity to the touch screen without contacting the touch screen and is allowed to be recognized as if the object is on the touch screen is referred to as a “proximity touch”. A behavior that an object actually contacts the touch screen is referred to as a “contact touch”. A position at which an object is subject to a proximity touch over the touch screen means a position at which the object vertically corresponds to the touch screen if the object is subject to the proximity touch.
The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch shift state, etc.). Furthermore, the controller 180 can process data (or information) corresponding to a proximity touch action and the proximity touch pattern detected through the proximity sensor 141 and, in addition, can output visual information corresponding to the processed data on the touch screen. In addition, the controller 180 can control the mobile terminal 100 so that different operations or different data (or information) are processed according to whether a touch for an identical point on the touch screen is a proximity touch or a contact touch.
The touch sensor senses a touch (or a touch input) applied to the touch screen (or the display 151) by using at least one of various touch schemes including a resistive-film scheme, a capacitive scheme, an infrared ray scheme, an ultrasonic scheme, and a magnetic field scheme. As an example, the touch sensor can be configured to convert a change in pressure applied to a specific part or a change in capacitance generated at a specific part of the touch screen into an electrical input signal. The touch sensor can be configured to detect a position or an area thereon which is touched by a touch object touching the touch screen, or pressure or capacitance at the time of the touch. Here, the touch object can be an object applying a touch on the touch sensor, for example, a finger, a touch pen, a stylus pen, or a pointer.
In this way, if there is a touch input on the touch sensor, a signal (signals) corresponding thereto is (are) transmitted to a touch controller. The touch controller processes the signal(s) and transmits corresponding data to the controller 180. Accordingly, the controller 180 can know which area of the display 151 is touched. Here, the touch controller can be a separate element other than the controller 180, or be the controller itself.
Furthermore, the controller 180 can perform different controls or an identical control according to a kind of the touch object, which touches the touch screen (or a touch key prepared other than the touch screen). Whether to perform different controls or an identical control according to a kind of the touch object can be determined according to a current operation state of the mobile terminal 100 or an application program being executed.
The above-described touch sensor and proximity sensor can sense independently or in a combined manner various types of touches on the touch screen, wherein the touches include a short (or a tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out, a swipe touch, and a hovering touch.
The ultrasonic sensor can recognize position information on a touch object by using an ultrasonic wave. The controller 180 can calculate a position of a wave generating source through information sensed by an optical sensor and a plurality of ultrasonic sensors. The position of the wave generating source can be calculated by using a property that a light is very faster than the ultrasonic wave, in other words, a time that a light arrives at an optical sensor is very shorter than a time that an ultrasound wave arrives at an ultrasonic sensor. In more detail, the position of the wave generating source can be calculated by using a time difference from a time if an ultrasonic wave arrives with a light considered as a reference signal.
Furthermore, from a view of a configuration of the input unit 120, the camera 121 includes at least one selected from a camera sensor (e.g., a CCD, or a CMOS sensor), a photo sensor (or an image sensor), and a laser sensor. The camera 121 and the laser sensor can be combined together and sense a touch of the sensing target for a 3-dimensional stereoscopic image. The photo sensor can be stacked on a display element, and this photo sensor scans a movement of the sensing target close to the touch screen. In more detail, the photo sensor includes photo diodes and transistors in rows/columns and scans a target mounted on the photo sensor by using an electrical signal changed according to an amount of a light applied to the photo diodes. In other words, the photo sensor performs coordinate calculation on the sensing target according to a change amount of the light and, through this, position information on the sensing target can be obtained.
The display 151 displays (outputs) information processed by the mobile terminal 100. For example, the display 151 can display execution screen information on the application program driven in the mobile terminal 100 or user interface (UI) information or graphic user interface (GUI) information according to the execution screen information.
In addition, the display 151 can be configured as a stereoscopic display displaying a stereoscopic image. A 3-dimensional display scheme such as a stereoscopic scheme (glasses type), an autostereoscopic scheme (glassless type), or a projection scheme (a holographic scheme) can be applied to the stereoscopic display.
The sound output unit 152 can output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception mode, a call mode or a recording mode, a speech recognition mode, or in a broadcast reception mode. The sound output unit 152 can output a sound signal related to a function (e.g., a call signal reception sound, or a message reception sound, etc.) performed in the mobile terminal 100. This sound output unit 152 can include a receiver, a speaker, or a buzzer, etc.
The haptic module 153 can generate various tactile effects that the user can feel. A representative example of the tactile effect that is generated by the haptic module 153 can be vibration. Strength and a pattern of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 can output different vibrations sequentially or by synthesizing them.
Besides the vibration, the haptic module 153 can generate various tactile effects including an effect by a stimulus such as a pin array moving vertically to a contact skin surface, a air discharge force or air absorptive power through an outlet or an inlet, brush against a skin surface, contact to an electrode, or static electricity, and an effect by reproducing a cold and warmth sense by using a device that heat absorption or heating is enabled.
The haptic module 153 can be implemented to transfer the tactile effect through a direct contact, and can also be implemented for the user to feel the tactile effect through a muscle sense of a finger or an arm. The haptic module 153 can be prepared two or more in number according to a configuration aspect of the mobile terminal 100.
The optical output unit 154 can output a signal for notifying an event occurrence by using a light from an optical source of the mobile terminal 100. The event occurred in the mobile terminal 100 can be exemplified with message reception, call signal reception, missed calls, alarm, schedule notification, email reception, or information reception through an application.
The signal output by the optical output unit 154 is implemented according to that the mobile terminal emits a monochromatic light or a multi-chromatic light towards the front or rear surface. The signal output can be completed if the mobile terminal detects that the user checks the event.
The interface unit 160 can play a role of a passage with all external devices connected to the mobile terminal 100. The interface unit 160 can receive data from the external device, receive power and transfer the power to each element inside the mobile terminal 100, or allow internal data of the mobile terminal 100 to be transmitted to the external device. For example, the interface 160 can include a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port connecting a device that an identification module is prepared, an audio input/output (I/O) port, a video input/output (I/O) port, or an earphone port, etc.
Furthermore, the identification module is a chip storing various pieces of information for authenticating user's authority for the mobile terminal 100 and can include a user identify module (UIM), a subscriber identity module (SIM), or a universal subscriber identity module (USIM). A device including the identification module (hereinafter, an ‘identification device’) can be manufactured in a smart card type. Accordingly, the identification device can be connected to the mobile terminal 100 through the interface unit 160.
In addition, if the mobile terminal 100 is connected to an external cradle, the interface unit 160 can be a passage through which power is supplied from the cradle to the mobile terminal 100 or a passage through which various command signals input from the cradle by the user are delivered. The various command signals or the power input from the cradle can operate as signals for perceiving that the mobile terminal 100 is accurately mounted in the cradle.
The memory 170 can store a program for operations of the controller 180 and temporarily store input/output data (e.g., a phone book, messages, still images, videos, etc.). The memory 170 can store data about vibrations of various patterns and sounds at the time of a touch input on the touch screen.
The memory 170 can include at least one storage medium type among a flash memory type, a hard disk type, a Solid State Disk (SSD) type, a Silicon Disk Drive (SDD) type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk and an optical disc. The mobile terminal 100 can operate in relation to a web storage performing a storage function of the memory 170 over the internet.
Furthermore, as described above, the controller 180 normally controls overall operations and an operation related to an application program of the mobile terminal 100. For example, if a state of the mobile terminal satisfies a set condition, the controller 180 executes or releases a lock state that limits an input of a user's control command to applications.
In addition, the controller 180 can perform a control or a process related to a voice call, data communication, or a video call, etc., or can perform a pattern recognition processing for recognizing a written input and a drawing input performed on the touch screen as a character and an image, respectively. Furthermore, the control 180 can combine and control any one of or a plurality of the above-described elements in order to implement various embodiments to be described below in the mobile terminal 100.
The power supply unit 190 receives external or internal power under a control of the controller 180 and supplies power necessary for operating each element. The power supply unit 190 includes a battery. The battery can be an embedded battery that is rechargeable and can be detachably coupled for charging.
The power supply unit 190 can include a connection port, and the connection port can be configured as an example of the interface 160 to which an external charger providing power is electrically connected for charging the battery. As another example, the power supply unit 190 can be configured to charge the battery in a wireless manner without using the connection port. In this instance, the power supply unit 190 can receive, from an external wireless power transmitting device, power by using one or more of an inductive coupling manner based on a magnetic induction phenomenon and a magnetic resonance coupling manner based on an electromagnetic resonance phenomenon. Hereinafter, various embodiments can be implemented in a recording medium that is readable with a computer or a similar device by using software, hardware, or a combination thereof.
Next, description is made about a communication system realizable through the mobile terminal 100 according to an embodiment. Firstly, the communication system can use different wireless interfaces and/or a physical layer. For example, the wireless interface available by the communication system can include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications Systems (UMTS)(in particular, Long Term Evolution (LTE), or Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), or etc.
Hereinafter, for convenience of explanation, description is made limitedly to CDMA. However, it is obvious that the embodiments can be applied to all communication systems including an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system as well as a CDMA wireless communication system.
The CDMA wireless communication system can include at least one terminal 100, at least one base station (BS, also can be referred to as Node B or Evolved Node B), at least one BS controller (BSC) and a mobile switching center (MSC). The MSC can be configured to be connected to the Public Switched Telephone Network (PSTN) and BSCs. The BSCs can be connected to the BS in pair through a backhaul line. The backhaul line can be prepared according to at least one selected from E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, and xDSL. Accordingly, the plurality of BSCs can be included in a CDMA wireless communication system.
Each of a plurality of BSs can include at least one sector, and each sector can include an omni-directional antenna or an antenna indicating a specific radial direction from the BS. In addition, each sector can include two or more antennas having various types. Each BS can be configured to support a plurality of frequency allocations and each of the plurality of allocated frequencies can have specific spectrum (e.g., 1.25 MHz, or 5 MHz).
An intersection between the sector and the frequency allocation can be called as a CDMA channel. The BS can be called as a base station transceiver subsystem (BTSs). In this instance, one BSC and at least one BS are called together as a “base station”. The base station can also represent a “cell site”. In addition, each of a plurality of sectors for a specific BS can also be called as a plurality of cell sites.
A broadcasting transmitter (BT) transmits a broadcast signal to terminals 100 operated in a system. The broadcast reception module 111 illustrated in
Furthermore, in the CDMA wireless communication system, a global positioning system (GPS) can be linked for checking a location of the mobile terminal 100. A satellite is helpful for grasping the location of the mobile terminal. Useful location information can be obtained by less than two or at least two satellites. Here, the location of the mobile terminal 100 can be tracked by using all techniques, which are capable of tracking the location, as well as a GPS tracking technique. In addition, at least one of GPS satellites can be selectively or additionally responsible for transmitting satellite digital multimedia broadcasting (DMB).
The location information module 115 prepared in the mobile terminal 100 is for detecting, operating or identifying the location of the mobile terminal 100, and can representatively include a GPS module and a WiFi module. If necessary, the location information module 115 can alternatively or additionally perform any function of other modules in the wireless communication unit 110 for obtaining data for the location of the mobile terminal 100.
The GPS module 115 can precisely calculate 3D current location information according to latitude, longitude, and altitude by calculating distance information from three or more satellites and precise time information, and by applying a trigonometry to the calculated information. A method is currently widely used that calculates location and time information using three satellites, and corrects an error in the calculated location and time information using another satellite. The GPS module 115 can calculate speed information by continuously calculating a current location in real time. However, it is difficult to precisely measure the location of the mobile terminal 100 by using the GPS module in a dead zone, such as an indoor area, of the satellite signal. Accordingly, in order to compensate for location measurement in the GPS manner, a WiFi positioning system (WPS) can be used.
The WPS is a technique for tracking the location of the mobile terminal 100 using a WiFi module prepared in the mobile terminal 100 and a wireless access point (AP) transmitting or receiving a wireless signal to or from the WiFi module, and can mean a location measurement technique based on a wireless local area network (WLAN) using WiFi.
The WPS can include a WiFi positioning server, the mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database storing arbitrary wireless AP information. The mobile terminal 100 connected to the wireless AP can transmit a location information request message to the WiFi positioning server.
The WiFi positioning server extracts information on the wireless AP connected to the mobile terminal 100 based on the location information request message (or a signal) of the mobile terminal 100. The information on the wireless AP connected to the mobile terminal 100 can be transmitted to the WiFi positioning server through the mobile terminal 100 or transmitted to the WiFi positioning server from the wireless AP.
The information on the wireless AP, which is extracted based on the location information request message of the mobile terminal 100, can be at least one selected from a MAC address, a Service Set Identification (SSID), a Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), channel information, Privacy, a Network Type, Signal Strength, and Noise Strength.
As described above, the WiFi positioning server can receive information on the wireless AP connected to the mobile terminal 100, and extract wireless AP information corresponding to the wireless AP to which the mobile terminal is being connected from the pre-constructed database. In addition, information on arbitrary wireless APs, which is stored in the database, can be information on a MAC Address, an SSID, channel information, Privacy, a Network Type, latitudinal and longitudinal coordinates of a wireless AP, a building name and floor on which the wireless AP is located, indoor detailed location information (GPS coordinates available), an address of an owner of the wireless AP, a phone number, and etc. In addition, in order to remove a wireless AP provided by using a mobile AP or an illegal MAC address in the location measurement process, the WiFi positioning server can extract a predetermined number of pieces of wireless AP information in the descending order of an RSSI.
Thereafter, the WiFi positioning server can extract (or analyze) location information on the mobile terminal 100 by using at least one piece of wireless AP information extracted from the database. The location information of the mobile terminal 100 is extracted (or analyzed) by comparing the stored and the received wireless AP information.
As a method of extracting (or analyzing) location information on the mobile terminal 100, a cell-ID method, a fingerprint method, a trigonometry, and a landmark method can be used. The cell-ID method is a method of determining a location of a wireless AP having strongest strength from among surrounding wireless AP information collected by a mobile terminal. This method is advantageous in that implementation is simple, an additional cost is not necessary, and location information can be rapidly obtained. However, if installation intensity of a wireless AP is lower, positioning precision becomes lowered.
The fingerprint method is a method of selecting a reference location in a service area, collecting signal strength information, and estimating a location through signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to construct a database for propagation characteristics in advance.
The trigonometry is a method of operating a location of a mobile terminal based on a distance between coordinates of at least three wireless APs and the mobile terminal. For estimating the distances between the mobile terminal and the wireless APs, signal strength is converted into distance information, or a time of arrival (ToA) of a wireless signal, a time difference of arrival (TDoA) of a wireless signal, an angle of arrival (AoA) of a wireless signal can be used.
The landmark method is a method of measuring a location of a mobile terminal by using a landmark transmitter. Besides the above-described methods, various algorithms can be used for extracting (or analyzing) location information on a mobile terminal. The location information on the mobile terminal 100 extracted in this way can be transmitted to the mobile terminal 100 through the WiFi positioning server and the mobile terminal 100 can obtain the location information.
The mobile terminal 100 can obtain location information by being connected to at least one wireless AP. In addition, the number of wireless APs requested for obtaining the location information on the mobile terminal 100 can be variously varied according to a wireless communication environment in which the mobile terminal 100 is located.
Various embodiments of a method for operating the flexible display device 200 will be described. The embodiments can be applied to both the stretchable display device 200_1 described above with reference to
For example, if an execution window of an email application is displayed on a first region and an execution window of an Internet application is displayed on a second region, if a link included in the execution window of the Internet application is selected, the controller 290 can maintain the execution window of the email application displayed on the first region, while switching the execution window of the Internet application displayed on the second region to a website window corresponding to the selected link. The plurality of regions that form the extended screen can include different information.
In one embodiment, the information displayed on the extended screen can be any one of an execution screen of an application and multimedia content, but this is merely an example. The controller 290 determines whether the extended screen is reduced in size while the displayed information is selected (S503). In one embodiment, a request for selecting the information displayed on the extended screen can be made by a touch input, but this is merely an example. The controller 290 can detect whether the size of the screen is reduced while any one of the plurality of regions forming the extended screen is selected.

For example, the controller 290 can capture a region including the selected information by using a screen capture function to store a captured image.
The controller 290 can add stored information to a recent access list. The recent access list provides information on an application recently executed, information on a broadcast program recently viewed, and information on content recently played through the flexible display device 200. The controller 290 displays the recent access list including a plurality of items in response to a request (S507). In one embodiment, the request for displaying the recent access list can be a command of selecting a menu button 681 included in a key input region 680.
In another embodiment, the request for displaying the recent access list can be a command of selecting a function button provided to the intermediate case 220. In one embodiment, the recent access list can include at least one execution item corresponding to an application recently executed and at least one storage item corresponding to an execution window of an application recently stored. Further, the at least one storage item can correspond to an image captured and stored. In another embodiment, each of the at least one storage item can be an execution window of a stored application.

That is, the screen 600 can be in a state of being extended by as much as the first region 610, the second region 630, and the third region 650. However, an embodiment is not limited thereto, and the screen 600 can be in a state of being extended only by as much as the second region 630 and the third region 650. That is, the first region 610 included in the screen 600 can be a region representing a state prior to deformation of the screen of the display 250.
The screen 600 can include the key input region 680 in addition to the plurality of regions 610, 630, and 650. The key input region 680 can be a region for controlling the screen 600 according to a touch input. The key input region 680 can include a home button 683 for moving to a home screen, a back button 685 for returning to a previous screen, and the menu button 681 for editing information displayed on the screen.

In another embodiment, when the execution window 631 of the gallery application includes a plurality of images, only an image selected from among the plurality of images can be stored. That is, in this instance, the controller 290 can store a selected image alone without capturing the execution window 631 of the gallery application. The user can store selected information by reducing the screen while selecting information to be viewed at a later time, without providing an additional input such as a screen capture input.
The plurality of items can include the execution window 611 of the email application recently executed, and the execution window 631 of the gallery application and the execution window 651 of the Internet application stored as described above with reference to
