[First Embodiment]
Hereinafter, embodiments of the present invention will be described. FIG. 1 is a diagram for explaining the electronic apparatus according to the first embodiment. FIG. 2 is a diagram for explaining an example when the flexible display is accommodated. FIG. 3 is a block diagram for explaining the electronic apparatus of the first embodiment.

The electronic device 101 is a type including a flexible display 111. The electronic device 101 is, for example, a portable communication terminal, a portable game machine, a portable information terminal, or an electronic book reader.
The electronic device 101 includes a flexible display 111, a first wire 112, a second wire 113, a heat insulation unit 114, a supply unit 115, and a control unit 116.

  Since the flexible display 111 has flexibility, it can be bent or rolled. The flexible display 111 is a liquid crystal display, an organic EL (Electroluminescence) display, or the like.

  The first wire 112 is disposed on each of one end side and the other end side along the first direction A in the flexible display 111. The first wire 112 is made of a shape memory alloy that has been memorized in a curved state. When the temperature is lower than a predetermined temperature (for example, normal temperature), the first wire 112 is deformable (elongated as an example) and is in a shape that exceeds a predetermined temperature. The memorized curved state is obtained. When the current is supplied, the first wire 112 generates heat and changes from the current shape (for example, a state of extending linearly) to a curved state in which the shape is memorized. Accordingly, the flexible display 111 is curved.

Here, the curved state in which the shape is memorized is, for example, a curved state in a scroll shape.
The first wire 112 disposed on one end side and the first wire 112 disposed on the other end side bend in the same direction (for example, the front side in FIG. 1). The first wire 112 is curved along the first direction A. As the first wire 112 is bent, the flexible display 111 is bent.

  At this time, the second wire 113 is not supplied with current and is not heated, that is, a temperature lower than a predetermined temperature at which the shape is memorized (for example, room temperature). , Easy to bend. Therefore, the second wire 113 is bent as the first wire 112 and the flexible display 111 are bent.

  Accordingly, when a current is supplied to the first wire 112 to generate heat, for example, the flexible display 111 that has been straightened is bent into a scroll shape, thereby reducing the surface area exposed to the outside by combining the flexible display 111. Can be made compact.

  At this time, in order to maintain the curved state of the first wire 112, the current may be continuously supplied to the first wire 112. In this way, the flexible display 111 is naturally curved. Thus, it is possible to reduce the natural separation of the flexible display 111 from the combined state.

  Here, for example, since the first wire 112 is fixed to the flexible display, the flexible display 111 is deformed (for example, curved) with the deformation (for example, curved) of the first wire 112.

  In the present embodiment, the first wire 112 is provided around the flexible display 111 along the first direction A, but is not limited thereto, and may be provided inside the flexible display 111. Alternatively, it may be attached to the back side of the flexible display 111. Further, the number of the first wires 112 is not limited to two, and may be one or three or more.

  The second wire 113 is arranged on each of one end side and the other end side along the first direction A in the flexible display 111. The second wire 113 is made of a shape memory alloy that has been memorized in a straightly stretched state. When the temperature is lower than a predetermined temperature (for example, normal temperature), the second wire 113 is in a deformable state (curved state as an example) and becomes a predetermined temperature or higher. , The shape memorized straight. When the electric current is supplied, the second wire 113 generates heat and changes from the current shape (for example, a curved state) to a state in which the shape is stored and straightly extended. Along with this, the flexible display 111 extends straight. The second wire 113 arranged on one end side and the second wire 113 arranged on the other end side extend straight in the same direction (for example, the first direction A). The second wire 113 is straight in the first direction A. As the second wire 113 extends, the flexible display 111 becomes planar.

  At this time, the first wire 112 is not supplied with current and is not heated, that is, at a temperature lower than a predetermined temperature at which the shape is memorized (for example, room temperature). , Easy to bend. Accordingly, the first wire 112 is bent as the second wire 113 and the flexible display 111 are bent.

  Thus, when a current is supplied to the second wire 113 to generate heat, for example, the flexible display 111 that has been compacted into a scroll shape is released from the scroll shape, and the user can watch the display.

  Further, at this time, in order to maintain the state in which the second wire 113 is straightened, current may be continuously supplied to the second wire 113, and in this way, the flexible display 111 is straightened. It is possible to reduce the situation that the state is naturally released and it becomes difficult for the user to view the flexible display 111 while viewing it.

  Note that the second wire 113 changes from a current shape to a straightly stretched shape stored in shape when the current is supplied and generates heat. However, the present invention is not limited to this. It is good also as changing to the state curved so that may be cancelled | released.

  In the present embodiment, the second wire 113 is disposed on the inner side of the first wire 112, but the present invention is not limited to this, and the second wire 113 may be disposed on the outer side of the first wire 112. Good.

  The first wire 112 and the second wire 113 may be connected to a heat sink (not shown). When the first wire 112 and the second wire 113 are connected to the heat sink, when the generation of heat in the first wire 112 or the second wire 113 is finished, the first wire 112 or the second wire 113 can be immediately cooled. it can. Therefore, as an example, even when heat is generated by the second wire 113 after generation of heat by the first wire 112 is completed, the flexible display 111 can be changed from a curved state to an extended state.

  The heat insulating part 114 is a heat insulating material that insulates the first wire 112 and the second wire 113. The heat insulating portion 114 is disposed between the first wire 112 and the second wire 113. Or the heat insulation part 114 is distribute | arranged so that each of the 1st wire 112 and the 2nd wire 113 may be covered. The heat insulating part 114 has flexibility.

  The supply unit 115 supplies current to the first wire 112 and the second wire 113. The supply unit 115 supplies current to the first wire 112 and the second wire 113 independently. The first wire 112 generates Joule heat when current is supplied from the supply unit 115, and is bent by this heat. The second wire 113 generates Joule heat when the current is supplied from the supply unit 115 and extends due to this heat.

  The controller 116 controls the supply unit 115 to supply current only to the first wire 112 when the first trigger occurs. The control unit 116 controls the supply unit 115 to supply current only to the second wire 113 when the second trigger occurs.

For example, the first trigger is when the power of the electronic device 101 is turned off (disconnected) by operating a power button (not shown) that constitutes an operation unit (not shown) of the electronic device 101. Occur. Alternatively, for example, the first trigger is operated to store the flexible display 111 by operating a storage button (not shown) that constitutes an operation unit (not shown) of the electronic device 101. Occurs when. Alternatively, for example, when the electronic device 101 is a mobile communication terminal, the first trigger is generated when the mobile communication terminal shifts to a communication standby state. When a current is supplied only to the first wire 112, the flexible display 111 is bent as shown in FIG.
In addition, the electronic device 101 may include a line-of-sight detection unit that detects a user's line of sight, and the first trigger may be that the line of sight of the flexible display 111 by the user is not detected.

For example, the second trigger is generated when an operation for extending the flexible display 111 is performed by operating an extension button (not shown) constituting an operation unit (not shown) of the electronic device 101. To do. Alternatively, it occurs when a power button (not shown) constituting an operation unit (not shown) of the electronic device 101 is operated to turn on the electronic device 101. For example, when the electronic device 101 is a mobile communication terminal, the second trigger is generated when an incoming call is received by the mobile phone. When an electric current flows only through the second wire 113, the flexible display 111 extends as shown in FIG. When the flexible display 111 is in the state shown in FIG. 1, an image can be displayed.
Further, the display of the screen may be used as the second trigger, and in this case, the flexible display 111 can be set in the expanded state in conjunction with the display of the screen.

  Such an electronic device 101 supplies a current to either the first wire 112 or the second wire 113 in response to a trigger, so that the flexible display 111 can be automatically housed or deployed as the wire is bent. it can.

[Second Embodiment]
Next, a second embodiment will be described. FIG. 4 is a diagram for explaining an electronic apparatus according to the second embodiment.
The electronic device 201 is a type including a flexible display 211. The electronic device 201 is, for example, a portable communication terminal, a portable game machine, a portable information terminal, or an electronic book reader.

The electronic apparatus 201 includes a flexible display 211, a motor (first motor 212), and a control unit 214.
The flexible display 211 is the same type as the flexible display 111 described in the first embodiment.

  The motor (first motor 212) includes a rotating shaft 213 to which one end side of the flexible display 211 is connected. When the first motor 212 rotates the rotation shaft 213 in the second direction C, the flexible display 211 is wound around the rotation shaft 213 and stored. When the first motor 212 rotates the rotating shaft 213 in the third direction D, the flexible display 211 is pulled out and can display an image. The second direction is a rotation direction opposite to the third direction.

  As the first motor 212, for example, a vibration motor can be used. When the electronic device 201 is a mobile communication terminal, the vibration motor is a motor that generates vibration in order to notify that there is an incoming call or reception, for example. For example, the first motor 212 and the rotating shaft 213 are arranged inside a housing (not shown) together with other electronic components.

  The control unit 214 controls the motor to rotate the rotation shaft 213 in the second direction C in order to accommodate the flexible display 211 when the first trigger is generated. The control unit 214 controls the motor to rotate the rotating shaft 213 in the third direction D opposite to the second direction C in order to extend the flexible display 211 when the second trigger occurs.

  The first trigger and the second trigger are, for example, the same triggers as the first trigger and the second trigger described in the first embodiment. When the first trigger is generated, the control unit 214 drives the first motor 212 to house the flexible display 211 in the above-described housing. When the second trigger occurs, the control unit 214 drives the first motor 212 to extend the flexible display 211 from the housing described above to the outside.

  Thereby, the electronic device 201 accommodates the flexible display 211 or extends the flexible display 211 in response to the trigger, so that the flexible display 211 can be accommodated automatically.

[Third Embodiment]
Next, a third embodiment will be described. FIG. 5 is a diagram for explaining an electronic apparatus according to the third embodiment.
The electronic device 301 is a type including a flexible display 311. The electronic device 301 is, for example, a portable communication terminal, a portable game machine, a portable information terminal, or an electronic book reader.

  The electronic device 301 includes a flexible display 311, an antenna 312, a drive unit 313, and a control unit 314.

  Since the flexible display 311 has flexibility, it can be bent or bent. The flexible display 311 is a liquid crystal display or an organic EL (Electroluminescence) display. The flexible display 311 is rectangular. For this reason, the flexible display 311 has two ends in each of the first direction A and the fourth direction B orthogonal to the first direction A.

  The antenna 312 can be expanded and contracted along the first direction A. The antenna 312 is a telescopic antenna. As an example, the antenna 312 is used to receive a broadcast wave. The antenna 312 engages at least at the intersection 311a between the one end along the first direction A and the one end along the fourth direction B in the flexible display 311 and the tip 312a. One end along the first direction A is the left end of the flexible display 311 in the case shown in FIG. One end portion along the fourth direction B is an end portion on the distal end side of the flexible display 311. That is, one end along the fourth direction B is the upper end of the flexible display 311 in the case shown in FIG. The intersection part 311a is the upper left corner of the flexible display 311 in the case shown in FIG. Therefore, the tip 312 a of the antenna 312 engages with the upper left corner of the flexible display 311. If the engagement position does not move, the tip 312a of the antenna 312 and the upper left corner of the flexible display 311 may be engaged by any means.

  The drive unit 313 extends and contracts the antenna 312. The drive unit 313 is, for example, a motor (second motor). For example, a gear (not shown) is disposed on the rotation shaft of the second motor. For example, the gear meshes with a rack (not shown) arranged at the base end portion 312 b of the antenna 312. The rack (antenna 312) moves based on the rotation of the gear according to the rotation of the second motor. In other words, the antenna 312 is housed (shrinked) by moving in the direction of arrow E or expanded by moving in the direction of arrow F, depending on the direction of rotation of the second motor.

  When the first trigger occurs, the control unit 314 controls the drive unit 313 so as to contract the antenna 312 in order to accommodate the flexible display 311. The control unit 314 controls the driving unit 313 to extend the antenna 312 in order to extend the flexible display 311 when the second trigger occurs.

The first trigger and the second trigger are, for example, the same triggers as the first trigger and the second trigger described in the first embodiment. Since the distal end portion 312a of the antenna 312 and the flexible display 311 are engaged, the flexible display 311 is also drawn when the antenna 312 contracts. For example, as in the second embodiment, the base end portion of the flexible display 311 may be connected to the rotation shaft of the motor (first motor 315). When the control unit 314 controls the drive unit 313 so that the antenna 312 is contracted, the control unit 314 controls the first motor 315 so that the rotation shaft rotates in the arrow C direction. Thereby, the flexible display 311 is accommodated so as to be wound around the rotating shaft. When the control unit 314 controls the drive unit 313 to extend the antenna 312, the control unit 314 controls the first motor 315 so that the rotation shaft rotates in the arrow D direction. Thereby, the flexible display 311 can be pulled out from the rotation axis and display an image.
The first trigger may be triggered by the end of reception of broadcast waves by the antenna 312 or the end of video display by the flexible display 311.
The second trigger may be triggered by the start of broadcast wave reception by the antenna 312 or the start of video display by the flexible display 311.

  As described above, since the electronic device 301 has the antenna 312 and the flexible display 311 engaged with each other, the flexible display 311 can be supported by the antenna 312 and the image can be easily viewed by the user. In addition, since the electronic device 301 interlocks the expansion and contraction of the antenna 312 and the storage or drawing of the flexible display 311, the flexible display 311 can be automatically stored.

[Fourth Embodiment]
Next, a fourth embodiment will be described. FIG. 6 is a diagram for explaining an electronic apparatus according to the fourth embodiment. FIG. 6A is a perspective view of an electronic device. FIG. 6B is a cross-sectional view of the electronic device. FIG. 7 is a block diagram for explaining an electronic apparatus according to the fourth embodiment.
The electronic device 401 is a type including a flexible display 412. The electronic device 401 is, for example, a portable communication terminal, a portable game machine, a portable information terminal, or an electronic book reader.

  The electronic device 401 includes a housing 411, a flexible display 412, a detection unit 413, and a control unit 414.

  The housing 411 can accommodate the flexible display 412 therein. For example, the housing 411 can be accommodated so as to wind up the flexible display 412. The housing 411 includes an opening 411a through which the flexible display 412 passes.

  The flexible display 412 is pulled out from the housing 411 when in use. That is, the flexible display 412 is accommodated in the housing 411 through the opening 411a. The flexible display 412 is pulled out from the housing 411 through the opening 411a.

  The detection unit 413 detects a portion of the flexible display 412 that is pulled out from the housing 411. The detection unit 413 is, for example, a piezoelectric element sheet that is disposed on the flexible display 412. The piezoelectric element sheet is disposed on substantially the entire surface of the flexible display 412. Alternatively, the piezoelectric element sheet is disposed on the edge of the flexible display 412. When the piezoelectric element sheet is disposed on the edge of the flexible display 412, the piezoelectric element sheet is preferably disposed on one or two edges along the direction in which the flexible display 412 is pulled out from the housing 411. The piezoelectric element sheet has a plurality of piezoelectric elements (not shown) arranged on the entire surface. When the piezoelectric element sheet is curved, the piezoelectric element disposed in the curved portion outputs an electrical signal to the control unit 414 based on detecting the pressure accompanying the bending.

  Based on the detection result of the detection unit 413, the control unit 414 displays an image in a portion of the flexible display 412 that is pulled out from the housing 411. The control unit 414 receives an electrical signal output from the piezoelectric element. When the control unit 414 receives the electrical signal, the control unit 414 specifies the position where the flexible display 412 is bent based on the position of the piezoelectric element that has output the electrical signal. Here, in the case illustrated in FIG. 6B, the portion where the flexible display 412 is curved is limited. The control unit 414 is pulled out from the housing 411 in the flexible display 412 based on the position (curved position) of the flexible display 412, the distance from the curved position to the opening 411 a, the length of the flexible display 412, and the like. Identify the part that is. The identified portion of the flexible display 412 is an area that can be visually recognized by the user when an image is displayed. Therefore, when the image is displayed, the control unit 414 adjusts the size of the image by various methods, and displays the adjusted image in the specified portion. In addition, the control unit 414 changes the direction in which an image is displayed according to the size of the portion pulled out from the housing 411 in the flexible display 412.

  Further, the control unit 414 may change the number of colors of the image displayed on the flexible display 412 based on the detection result of the detection unit 413. That is, the control unit 414 changes the number of colors of the image in accordance with the length of the flexible display 412 drawn from the housing 411. For example, when the length of the flexible display 412 pulled out from the housing 411 is less than the first threshold A, the control unit 414 displays an image on a specific portion of the flexible display 412 with a 24-bit color. That is, the control unit 414 transmits 24-bit color image data to the display unit. For example, when the length of the flexible display 412 pulled out from the housing 411 is greater than or equal to the first threshold A and less than the second threshold B (A <B), the control unit 414 uses the 18-bit color flexible display 412. An image is displayed on a specific part of. That is, the control unit 414 transmits 18-bit color image data to the display unit. For example, when the length of the flexible display 412 pulled out from the housing 411 is less than the second threshold value B, the control unit 414 displays an image on a specific portion of the flexible display 412 in 16-bit color. That is, the control unit 414 transmits 16-bit color image data to the display unit.

  Further, the control unit 414 may change the data transfer rate and the number of transfer data lines for the image displayed on the flexible display 412 based on the detection result of the detection unit 413. That is, the control unit 414 changes the data transfer rate and the number of transfer data lines in accordance with the length of the flexible display 412 drawn from the housing 411. For example, when the length of the flexible display 412 pulled out from the housing 411 is less than the first threshold A, the control unit 414 sets the image transfer clock to a low speed, or the clock frequency or the data transfer rate (bps). , And an image is displayed on a specific portion of the flexible display 412. For example, when the length of the flexible display 412 pulled out from the housing 411 is equal to or greater than the first threshold A and less than the second threshold B (A <B), the control unit 414 displays the image transfer clock (clock frequency). Alternatively, an image is displayed on a specific portion of the flexible display 412 with an image transfer rate (bps) as a standard. For example, when the length of the flexible display 412 pulled out from the housing 411 is equal to or longer than the second threshold B, the control unit 414 sets the image transfer clock to a high speed, or the clock frequency or the data transfer rate (bps). Is increased to display an image on a specific portion of the flexible display 412.

  Thus, by changing the image transfer clock in accordance with the length of the flexible display being pulled out, the time taken to display the image can be made substantially constant even if the length of the flexible display changes. That is, for example, when the length of the flexible display is long, the time required for displaying an image can be further shortened by increasing the image transfer clock. Further, if the image transfer clock is set to a high speed when the length of the flexible display is short, the power consumption increases. Therefore, the increase in the power consumption can be reduced by reducing the image transfer clock.

  In the case of high-speed serial transfer or the like, since the transfer rate can be increased by increasing the number of data lanes, the control unit 414 changes the number of data lanes by the same processing as described above. Thus, the transfer time can be adjusted. That is, for example, when the length of the flexible display 412 pulled out from the housing 411 is less than the first threshold A, the number of data lanes is made smaller than the number of reference data lanes, and the flexible display 412 is pulled out from the housing 411. When the length of the flexible display 412 is equal to or longer than the second threshold B, the number of data lanes is made larger than the number of reference data lanes.

  Further, the control unit 414 may change the luminance of the flexible display 412 based on the detection result of the detection unit 413. That is, the control unit 414 changes the luminance of the flexible display 412 according to the length of the flexible display 412 drawn from the housing 411. For example, when the length of the flexible display 412 pulled out from the housing 411 is less than the first threshold A, the control unit 414 sets the luminance of the flexible display 412 as the first setting X and sets the flexible display 412 to Display an image in a specific part. For example, when the length of the flexible display 412 pulled out from the housing 411 is equal to or more than the first threshold A and less than the second threshold B (A <B), the control unit 414 sets the luminance of the flexible display 412. As the second setting Y (X> Y), an image is displayed on a specific portion of the flexible display 412. For example, when the length of the flexible display 412 pulled out from the housing 411 is less than the second threshold B, the control unit 414 sets the luminance of the flexible display 412 as the third setting Z (Y> Z). Then, an image is displayed on a specific portion of the flexible display 412.

  Thereby, the electronic device 401 can perform an appropriate image display. In addition, since the electronic device 401 adjusts the number of colors, it is possible to prevent an increase in the amount of image data transmitted to the flexible display 412. Further, since the electronic device 401 adjusts the transfer rate or the number of transfer data lines, the transfer time of the image data can be adjusted. In addition, since the electronic device 401 adjusts the luminance, it is possible to prevent an image from being displayed with a high luminance in the case of a larger screen and to suppress power consumption.

  Further, the control unit 414 may change the number of data based on the detection result of the detection unit 413. That is, the control unit 414 controls the use of the data expansion function according to the length of the flexible display 412 drawn from the housing 411. As an example, the data extension function is a double-angle display function. As a specific example, when the length of the flexible display 412 is longer than the threshold, the control unit 414 expands the data for one pixel to four pixels for QHD (950 × 540) data, The flexible display 412 is caused to display full HD (1920 × 1080).

In the above-described embodiment, the example in which the detection unit is a piezoelectric element sheet has been described. However, the present invention is not limited to this embodiment.
For example, the detection unit may be configured by a capacitive touch panel arranged on the flexible display and a GND plate arranged inside the housing. In this example, based on detecting the GND plate with the capacitive touch panel, the control unit acquires the pull-out amount of the touch panel display. In addition, specifically, the GND plate may be provided in the vicinity of the drawer opening of the flexible display 412 inside the housing.
In addition, for example, the detection unit may be configured by a capacitive touch panel disposed on the flexible display and a GND pattern disposed on the flexible display. In this example, based on detecting the capacitance of the touch panel display itself with the capacitive touch panel, the control unit acquires the pull-out amount of the touch panel display.

Further, for example, the detection unit may be configured by a plurality of magnets arranged on the flexible display and a magnetic sensor arranged inside the housing. In this example, based on detecting the magnetic force of the magnet by the magnetic sensor, the control unit acquires the pull-out amount of the touch panel display.
Further, for example, the detection unit may be configured by an optical sensor disposed inside the housing and a plurality of patterns disposed on the flexible display and detectable by the optical sensor. In this example, based on detecting the light reflected by the pattern by the optical sensor, the control unit obtains the pull-out amount of the touch panel display.
