[0046] Figure 3 is a flowchart illustrating a modified example of a program executed by an arithmetic unit of an information processor according to an embodiment of the present invention.

[0047] <Information Processor>

[0048] The information processor 100 described in this embodiment includes an arithmetic device 110. The arithmetic device 110 receives bending position data SENS and an operation instruction INPUT including a display termination instruction, and supplies image data VIDEO. The arithmetic device 110 includes an arithmetic unit 111 and a storage unit 112 that stores a program executed by the arithmetic unit 111 (see Figure 1A ).

[0049] The information processor 100 further includes an input / output device 120. The input / output device 120 receives the image data VIDEO, and supplies the bending position data SENS and the operation instruction INPUT including the display termination instruction. The input / output device 120 includes a bendable display unit 122 and a bending position sensor 123 that detects the bending position of the display unit 122 and supplies the bending position data SENS (see Figure 1B1 ).

[0050] <Program>

[0051] The program executed by the arithmetic unit 111 includes the following steps (see Figure 2A and 2B ).

[0052] In the first step, initialize a timer or the like (see (S1) in Figure 2A ). Note that this initialization step also includes an operation of reading out image data used in the subsequent interrupt processing.

[0053] In the second step, allow interrupt processing. When interrupt processing is allowed, the main processing can be stopped and the subsequent interrupt processing can be executed (see (S2) in Figure 2A ).

[0054] In the third step, display the image generated in the interrupt processing allowed in the second step (see (S3) in Figure 2A ).

[0055] In the fourth step, if the display termination instruction is not input in the interrupt processing, the operation returns to the third step, and if the display termination instruction is input in the interrupt processing, it proceeds to the fifth step (see (S4) in Figure 2A ).

[0056] In the fifth step, the program is terminated (refer to (S5) in Figure 2A ).

[0057] An explanation of the interrupt processing is given (refer to Figure 2B ). Note that when the interrupt processing is permitted, the arithmetic unit can receive an instruction and execute the interrupt processing. The arithmetic unit that receives an instruction and executes the interrupt processing stops the main processing and executes the interrupt processing. For example, the arithmetic unit that receives items related to the above instruction executes the interrupt processing and stores the execution result in the storage unit. Then, the arithmetic unit that resumes from the interrupt processing can restart the main processing based on the execution result of the interrupt processing.

[0058] In the sixth step, a display termination instruction and the bending position data SENS are received. A user of the information processor 100 can input a display termination instruction using the input unit 121, for example (refer to (T6) in Figure 2B ).

[0059] In the seventh step, if the bending position data SENS is not supplied in the sixth step, the operation proceeds to the eighth step, and if the bending position data SENS is supplied in the sixth step, the operation proceeds to the ninth step (refer to (T7) in Figure 2B ). For example, when the display unit 122 in the bent state becomes the non-bent state and the supply of the bending position data SENS stops, the operation proceeds to the eighth step. Conversely, when the display unit 122 becomes the bent state and the bending position data SENS is supplied, the operation proceeds to the ninth step.

[0060] In the eighth step, an image to be displayed on the display unit 122 is generated. Note that the image generated in this step is not divided at a position where the display unit 122 can be bent. For example, an image can be generated from the image data read in the first step (refer to (T8) in Figure 2B ).

[0061] In the ninth step, an image divided into a first region 122(a) and a second region 122(b) at the bending position is generated (refer to (T9) in Figure 1B2 and Figure 2B ). Note that the dashed line 100F indicates the bending position.

[0062] Although the case where the display unit 122 is bent once along one line is described in the present embodiment, one embodiment of the present invention is not limited thereto. For example, the display unit 122 can be bent along a plurality of lines multiple times and an image divided at a plurality of bending positions can be displayed.

[0063] In the tenth step, the operation resumes from the interrupt processing (refer to (T10) in Figure 2Bin (T10)).

[0064] In the information processor 100 according to an embodiment of the present invention described above, when the display unit 122 is bent, the display area is divided into a first area 122(a) and a second area 122(b), and image data is displayed in each area. In this way, one display area can be divided into two areas at the bending position. Therefore, for example, different images or images for different purposes can be displayed in each area.

[0065] In addition, a novel information processor that is bendable and highly portable can be provided. Furthermore, a novel information processor that can display information on a large seamless screen can be provided. Note that in this specification, "image" includes information that can be visually obtained, such as characters and symbols.

[0066] The arithmetic unit 110 described as an example in this embodiment includes an input / output interface 115 and a transmission channel 114.

[0067] The input / output interface 115 can supply data to the input / output device 120 and receive data from the input / output device 120.

[0068] The transmission channel 114 can supply data to the arithmetic unit 111, the storage unit 112, and the input / output interface 115. In addition, the arithmetic unit 111, the storage unit 112, and the input / output interface 115 can supply data to the transmission channel 114.

[0069] The input / output device 120 includes an input unit 121. The input unit 121 can supply a display termination instruction or the like.

[0070] Note that the display termination instruction is an instruction to terminate a program.

[0071] Note that these units cannot be clearly distinguished, and in some cases, one unit is also used as another unit or includes a part of another unit. For example, the touch screen is used as the display unit 122 and also as the input unit 121.

[0072] Next, each constituent element included in the information processor 100 according to an embodiment of the present invention will be described.

[0073] 《Input / Output Device》

[0074] The input / output device 120 is connected to the transmission channel 114 via the input / output interface 115. The input / output device 120 can supply data.

[0075] 《Display Unit》

[0076] The display unit 122 is flexible and thus can be bent.Figure 1B1 The display unit 122 is shown in a flat - unfolded state. Figure 1B2 The display unit 122 is shown bent to have one crease. Note that the number of creases is not limited to one, and the display unit 122 can be bent to have n creases (n is a natural number of 1 or more).

[0077] The specific structure of the bendable display unit 122 will be described in detail in Embodiment 2.

[0078] "Bending Position Sensor"

[0079] The bending position sensor 123 detects the bending position of the display unit 122 and supplies bending position data SENS. For example, when the bending position is predetermined, the sensor is arranged at that position. In the case of bending positions of multiple display units, multiple sensors are arranged in a linear or matrix form, whereby the coordinates of the bending position can be identified.

[0080] For example, the bending position sensor 123 can be arranged along the periphery of the display unit 122. In Figure 1B1 the information processor 100 shown, the bending position sensor 123 is arranged along the long - side direction of the display unit 122. Or, for example, the bending position sensor 123 can be arranged along the short - side direction.

[0081] Note that the bending position sensor 123 arranged to surround the display unit 122 can detect the bending positions in various directions (e.g., horizontal, vertical, and diagonal) across the display unit 122. Thus, the display unit 122 can be divided at various positions.

[0082] The bending position sensor 123 can be composed of, for example, a switch, a MEMS pressure sensor, or a pressure sensor, etc.

[0083] Specifically, a mechanical contact switch or a magnetic switch, etc. can be arranged on the display unit 122 to open or close the above - mentioned switch according to the unfolding or bending operation of the display unit 122.

[0084] Or, multiple pressure sensors can be arranged on the display unit 122. Specifically, a thin - film piezoelectric element can be attached to the display unit 122. By detecting the pressure increase accompanying the bending operation using the pressure sensor, the bending position can be known.

[0085] As the piezoelectric element, for example, an organic piezoelectric thin film can be used. Specifically, a piezoelectric thin film containing polyamino acid, a piezoelectric thin film containing polyvinylidene fluoride, a piezoelectric thin film containing polyester, or a piezoelectric thin film containing chiral polymer, etc. can be used.

[0086] Note that the piezoelectric element can be used as both an element for the bending position sensor 123 and an element for the pressure-sensitive touch screen.

[0087] 《Input Unit》

[0088] As the input unit 121, for example, a human-machine interface or the like can be used. Specifically, a keyboard, a mouse, or a touch screen or the like can be used.

[0089] For example, a user of the information processor 100 can input operation instructions including a display termination instruction or an instruction for selecting an image or the like by using the input unit 121. The user can also input an instruction for selecting a region or a page-turning instruction or the like.

[0090] In addition, the virtual bending position data SENS can be input by using the input unit 121. Thus, one display portion can be divided into two regions at a position corresponding to the position data input by the input unit 121. Therefore, for example, different images can be displayed in each region.

[0091] 《Other Structures》

[0092] As the input / output device 120, for example, a camera, a microphone, a read-only external storage unit, an external storage unit, a communication device, a scanner, a speaker, a printer, etc. can be used.

[0093] Specifically, examples of the camera include a digital camera and a digital video camera.

[0094] Examples of the external storage unit include a hard disk and a removable memory. Examples of the read-only external storage unit include a CD-ROM and a DVD-ROM.

[0095] Examples of the communication device include a network interconnecting device and a modem.

[0096] As an example of the use of the information processor 100, a soft keyboard can be displayed in the second region 122(b) of the display unit 122 divided into two regions.

[0097] For example, the first region 122(a) can be used for displaying an image, and the second region 122(b) can be used as the input unit 121. Specifically, by operating game software by using the soft keyboard, the information processor 100 can be used as a game machine.

[0098] When the display unit 122 includes a light-emitting element as a display element, it is preferable to display the character palette in a color brighter than the background, and the power consumption can be reduced at this time.

[0099] Since the seamlessly spliced display portion is divided into two regions, users can more easily track with their eyes an image moving from one region to another. Thus, for example, discomfort during operations between the two regions can be alleviated.

[0100] In addition, users can more easily track with their eyes an image moving from one region to another displayed by the arithmetic unit 110. Thus, users can accurately predict the position of an image traveling between the two regions.

[0101] For example, in games or the like, the movements of characters traveling between the two regions can be accurately predicted.

[0102] <Modification Example 1>

[0103] Refer to Figure 3 to describe the information processor of Modification Example 1 of the present embodiment.

[0104] Figure 3 It is a flowchart showing a modification example of a program executed by the arithmetic unit 111 of the information processor according to an embodiment of the present invention.

[0105] In the interrupt processing of the program executed by the arithmetic unit 111, the information processor described as Modification Example 1 of the present embodiment is different from that referred to in Figure 2A and 2B the information processor described. Hereinafter, the differences will be described in detail. The description of parts having the same structure is incorporated by reference above.

[0106] In Modification Example 1 of the present embodiment, the program includes the following interrupt processing instead of the above interrupt processing. In the sixth step, a display termination instruction and bending position data SENS (refer to Figure 3 (U6) in

[0107] In the seventh step, the operation proceeds to the eighth step when the bending position data SENS is not supplied in the sixth step, and proceeds to the tenth step when the bending position data SENS is supplied in the sixth step (refer to Figure 3 (U7) in

[0108] In the eighth step, one image is selected from a plurality of images. For example, in the first step, a plurality of image data are read out and displayed as tile-shaped initial images on the display unit 122. The user can select one image using the input unit 121 (refer to Figure 3 (U8) in

[0109] In the ninth step, an undivided image to be displayed on the display unit is generated from the one image selected in the eighth step (refer to Figure 3(U9) in

[0110] In the tenth step, two images are selected from the plurality of images. For example, the plurality of image data read in the first step can be displayed in a tiled manner, and the user can select two images using the input unit 121 (see Figure 3 (U10) in

[0111] In the eleventh step, an image that is divided into a first region 122(a) and a second region 122(b) at the bending position is generated from the two images selected in the tenth step (see Figure 3 (U11) in

[0112] In the twelfth step, the operation is resumed from the interruption processing (see Figure 3 (U12) in

[0113] In the information processor described as a modification example of the present embodiment, one display area can be divided into two areas at the bending position, and an image displayed on the display unit 122 can be selected.

[0114] <Modification Example 2>

[0115] See Figure 6A 、 6B1 and 6B2 to describe the information processor of Modification Example 2 of the present embodiment.

[0116] Figure 6A 、 6B1 and 6B2 are a flowchart and schematic diagrams showing modification examples of a program executed by the arithmetic unit 111 of the information processor according to an embodiment of the present invention.

[0117] In the interruption processing of the program executed by the arithmetic unit 111, the information processor described as Modification Example 2 of the present embodiment is different from the information processor described with reference to Figure 2A and 2B described below. Hereinafter, this difference will be described in detail. For parts that can use the same structure, the above description is incorporated by reference.

[0118] In Modification Example 2 of the present embodiment, the program includes the following interruption processing instead of the above interruption processing. In the sixth step, a display termination instruction and bending position data SENS are received (see Figure 6A (V6) in

[0119] In the seventh step, the operation proceeds to the eleventh step when the bending position data SENS is not supplied in the sixth step, and proceeds to the eighth step when the bending position data SENS is supplied in the sixth step (see Figure 6A (V7) in

[0120] In the eighth step, if the display unit 122 is not bent outward, the operation proceeds to the eleventh step, and if the display unit 122 is bent outward, the operation proceeds to the ninth step (refer to Figure 6A (V8) in

[0121] Note that whether the display unit 122 is bent inward or outward can be known by using, for example, an acceleration sensor or a shear force sensor.

[0122] Specifically, by using the acceleration sensors 100S provided at the four corners of the display unit 122 to detect the acceleration received at these four corners when the display unit 122 is bent, the trajectories of the four corners of the display unit can be calculated (refer to Figure 6B1 ). In this way, it can be known whether the display unit is bent inward or outward (refer to Figure 6B2 ).

[0123] In addition, a shear force sensor provided on the display unit 122 can also be used to know whether the display unit 122 is bent inward or outward.

[0124] In the ninth step, the bending position F closest to the center C of the display unit 122 is identified (refer to Figure 6A (V9) in

[0125] The bending position F can be identified based on the bending position data SENS supplied by the bending position sensor. For example, in the case of using a bending position sensor in which a plurality of pressure sensors are arranged linearly, the bending position F can be the position closest to the center C of the display unit 122 and where a pressure greater than a specified value is detected by the pressure sensor (refer to Figure 6B2 ).

[0126] In the tenth step, an image is generated in which the pixel values of the pixels between the bending position F and the end E closer to the bending position F are 0 (refer to Figure 6A (V10) in

[0127] Specifically, the area between the bending position F and the end E on the side closer to the bending position F is the second area 122(b), and the other area is the first area 122(a). In order to display an image having no shape, pattern, color, etc. in the second area, an image in which the pixel values of the pixels in the second area are, for example, 0 is generated (refer to Figure 6B2 ). Note that an image including various information can be displayed in the first area 122(a).

[0128] In the eleventh step, the operation is resumed from the interrupt process (refer to Figure 6A (V11) in

[0129] In the information processor described as a modified example of the present embodiment, the display unit can be bent outward, and display can be performed in a portion where the length from the bent position to the end portion is longer, and display in a portion where the length from the bent position to the end portion is shorter can be stopped. Thereby, power consumption consumed in an area not used by the user can be reduced. In addition, information displayed in an area not used by the user can be prevented from being seen by others.

[0130] The present embodiment can be appropriately combined with other embodiments in this specification.

[0131] Embodiment 2

[0132] In the present embodiment, an information processor according to an embodiment of the present invention will be described with reference to Figure 4A 、 4B 、4C, 4D1, and 4D2.

[0133] Figure 4A is a plan view showing the structure of an information processor 200 according to an embodiment of the present invention, Figure 4B is a side view showing the structure of the information processor 200. Note that the arrow in the drawing indicates the side on which display is performed.

[0134] Figure 4C is a side view showing Figure 4A a partial structure of the bending member 281 shown in.

[0135] Figure 4D1 and 4D2 are side views showing an example in which the display unit 222 is divided into two regions at the bending position of the input / output device 220.

[0136] <Plan view>

[0137] The information processor 200 includes an arithmetic unit 210 that receives bending position data and operation instructions and supplies image data. The information processor 200 further includes an input / output device 220 that receives image data and supplies bending position data and operation instructions (see Figure 4A ).

[0138] <Side view>

[0139] The input / output device 220 includes a bending member 281 and a display unit 222 that is supported to bend according to the bending of the bending member 281. Note that when viewed from the side, the display unit 222 is substantially located at the center of the bending member 281 (see Figure 4B ).

[0140] The bending member 281 is provided along each side of the opposite sides of the display unit 222.

[0141] The bending member 281 includes one or more hinge members 282 (refer to Figure 4C ). Thus, the bending member 281 can be bent at one or more positions. Note that the hinge member 282 may be provided with a ratchet mechanism or an anti-slip member, etc., so as to appropriately adjust the bending angle.

[0142] Figure 4D1 And 4D2 Each shows a state in which the bending member 281 is bent at the position 200F and the display unit 222 is divided into a first region 222(a) and a second region 222(b).

[0143] In Figure 4D1 , for example, the bending member 281 is bent inward so that the first region 222(a) faces the user and the second region 222(b) faces upward.

[0144] According to the program for the arithmetic unit 210, the display unit 222 is divided into a first region 222(a) and a second region 222(b) based on the bending position data supplied by the input / output unit 220.

[0145] For example, the display screen of the software capable of sending and receiving e-mails is displayed in the first region 222(a), and the soft keyboard is displayed in the second region 222(b). Thus, in the first region 222(a), the e-mail written with the soft keyboard displayed in the second region 222(b) can be displayed and confirmed.

[0146] In this way, the information processor 200 can be used as an e-mail sending / receiving device.

[0147] In Figure 4D2 , for example, the bending member 281 is bent outward so that the first region 222(a) faces the user and the second region 222(b) faces downward.

[0148] According to the program for the arithmetic unit 210, the display unit 222 is divided into a first region 222(a) and a second region 222(b) based on the bending position data supplied by the input / output unit 220.

[0149] For example, the display screen of the software capable of browsing images is displayed in the first region 222(a), and the display in the second region 222(b) is stopped. Thus, the first region 222(a) can be held at an angle at which the user can more easily browse the images displayed in the first region 222(a).

[0150] In this way, the information processor 200 can be used as a digital photo frame or an animation playback device, etc.

[0151] This embodiment can be appropriately combined with other embodiments in this specification.

[0152] Embodiment 3

[0153] In this embodiment, with reference to Figures 5A to 5C The structure of the input / output device of the information processor applicable to one embodiment of the present invention will be described.

[0154] Figure 5A It is a plan view for explaining the structure of the input / output device of the information processor applicable to one embodiment of the present invention.

[0155] Figure 5B It is Figure 5A A cross-sectional view along line A-B and line C-D in

[0156] Figure 5C It is Figure 5A A cross-sectional view along line E-F in

[0157] <Plan view>

[0158] The input / output device 300 described as an example of this embodiment includes a display unit 301 (refer to Figure 5A ).

[0159] The display unit 301 includes a plurality of pixels 302 and a plurality of imaging pixels 308. The imaging pixel 308 can detect touches such as fingers on the display unit 301. Therefore, a touch sensor can be formed by using the imaging pixel 308.

[0160] Each of the pixels 302 includes a plurality of sub-pixels (for example, sub-pixel 302R). In addition, a light-emitting element and a pixel circuit capable of supplying power for driving the light-emitting element are provided in the sub-pixel.

[0161] The pixel circuit is electrically connected to a wiring for supplying a selection signal and a wiring for supplying an image signal.

[0162] Furthermore, the input / output device 300 is provided with a scan line drive circuit 303g(1) capable of supplying a selection signal to the pixels 302 and an image signal line drive circuit 303s(1) capable of supplying an image signal to the pixels 302.

[0163] The imaging pixel 308 includes a photoelectric conversion element and an imaging pixel circuit for driving the photoelectric conversion element.

[0164] The imaging pixel circuit is electrically connected to a wiring for supplying a control signal and a wiring for supplying a power supply potential.

[0165] Examples of the control signal include a signal for selecting a imaging pixel circuit from which the recorded imaging signal is read out, a signal for initializing the imaging pixel circuit, and a signal for determining the time required for the imaging pixel circuit to detect light.

[0166] The input / output device 300 is provided with an imaging pixel driving circuit 303g(2) capable of supplying a control signal to the imaging pixel 308 and an imaging signal line driving circuit 303s(2) for reading out the imaging signal.

[0167] <Cross-sectional view>

[0168] The input / output device 300 includes a substrate 310 and a counter substrate 370 opposed to the substrate 310 (see Figure 5B ).

[0169] The substrate 310 is a laminate in which a flexible substrate 310b, a barrier film 310a for preventing unintended impurities from diffusing into the light-emitting element, and an adhesive layer 310c for bonding the barrier film 310a and the substrate 310b are laminated.

[0170] The substrate 310b includes a substrate 310b(1) on which a plurality of electrodes 310Y are arranged, a substrate 310b(2) on which a plurality of electrodes 310X are arranged, and a flexible printed circuit (FPC309(2)). The plurality of electrodes 310Y and the plurality of electrodes 310X can supply signals through the FPC309(2) (see Figure 5B and 5C ).

[0171] The electrodes 310Y and the electrodes 310X are arranged so as to cross each other, and a functional polymer 310p is provided between the electrodes 310Y and the electrodes 310X.

[0172] The electrodes 310Y, the electrodes 310X, and the functional polymer 310p provided between the electrodes 310Y and the electrodes 310X constitute a pressure sensor. Thus, the pressure sensor is configured in a matrix form to constitute a bending position sensor.

[0173] Note that a structure in which the resistance between the electrodes 310Y and the electrodes 310X is changed due to deformation caused by pressure can be adopted. For example, a piezoelectric polymer can be used as the functional polymer 310p. Specifically, the functional polymer 310p is deformed by pressure, increasing the contact area between the electrodes 310Y and the electrodes 310X, thereby reducing the resistance.

[0174] The counter substrate 370 is a laminate including a flexible substrate 370b, a barrier film 370a for preventing unintended impurities from diffusing into the light-emitting element, and an adhesive layer 370c for bonding the barrier film 370a and the substrate 370b (see Figure 5B ).

[0175] The sealant 360 adheres to the opposing substrate 370 and the substrate 310. The sealant 360, which also serves as an optical adhesive layer, has a refractive index higher than that of the atmosphere. A pixel circuit and a light-emitting element (e.g., the first light-emitting element 350R) are provided between the substrate 310 and the opposing substrate 370.

[0176] "Pixel Structure"

[0177] Each pixel 302 includes sub-pixels 302R, 302G, and 302B (see Figure 5C ). For example, pixels 302R, 302G, and 302B can emit red light, green light, and blue light, respectively. The sub-pixel 302R includes a light-emitting module 380R, the sub-pixel 302G includes a light-emitting module 380G, and the sub-pixel 302B includes a light-emitting module 380B.

[0178] For example, the sub-pixel 302R includes a first light-emitting element 350R and a pixel circuit that can supply power to the first light-emitting element 350R and includes a transistor 302t (see Figure 5B ). In addition, the light-emitting module 380R includes a first light-emitting element 350R and an optical element (e.g., a first color filter layer 367R).

[0179] The first light-emitting element 350R includes a first lower electrode 351R, an upper electrode 352, and a layer 353 containing a light-emitting organic compound between the first lower electrode 351R and the upper electrode 352.

[0180] The layer 353 containing a light-emitting organic compound includes light-emitting units 353a, 353b, and an intermediate layer 354 between the light-emitting units 353a and 353b.

[0181] The light-emitting module 380R includes a first color filter layer 367R on the opposing substrate 370. The color filter layer allows light of a specific wavelength to pass through, for example, a layer that selectively allows red light, green light, or blue light to pass through. In addition, an area through which light emitted from the light-emitting element passes can also be provided.

[0182] For example, the light-emitting module 380R includes a sealant 360 that also serves as an optical adhesive layer and is in contact with the first light-emitting element 350R and the first color filter layer 367R.

[0183] The first color filter layer 367R is located in an area overlapping the first light-emitting element 350R. Therefore, a part of the light emitted from the first light-emitting element 350R passes through the sealant 360, which also serves as an optical adhesive layer, and the first color filter layer 367R, and is emitted to the outside of the light-emitting module 380R as shown by the arrows in Figure 5B and 5C .

[0184] "Structure of Display Panel"

[0185] The input / output device 300 includes a light-shielding layer 367BM on the counter substrate 370. The light-shielding layer 367BM is provided so as to surround a colored layer (for example, the first colored layer 367R).

[0186] The input / output device 300 includes an antireflection layer 367p in a region overlapping with the display unit 301. As the antireflection layer 367p, for example, a circular polarizer can be used.

[0187] The input / output device 300 includes an insulating film 321. The insulating film 321 covers the transistor 302t. Note that the insulating film 321 can be used as a layer for flattening the unevenness caused by the pixel circuit. In addition, an insulating film laminated with a layer capable of preventing the diffusion of impurities into the transistor 302t or the like can be used as the insulating film 321.

[0188] The input / output device 300 includes a light-emitting element (for example, the first light-emitting element 350R) on the insulating film 321.

[0189] The input / output device 300 includes a partition wall 328 (refer to Figure 5C ) overlapping with an end portion of the first lower electrode 351R on the insulating film 321. In addition, a spacer 329 for controlling the distance between the control substrate 310 and the counter substrate 370 is provided on the partition wall 328.

[0190] "Structure of Image Signal Line Driving Circuit"

[0191] The image signal line driving circuit 303s(1) includes a transistor 303t and a capacitor 303c. Note that the driving circuit can be formed on the same substrate as the pixel circuit in the same process as the pixel circuit.

[0192] "Structure of Imaging Pixel"

[0193] Each imaging pixel 308 includes a photoelectric conversion element 308p and an imaging pixel circuit for detecting the light received by the photoelectric conversion element 308p. The imaging pixel circuit includes a transistor 308t.

[0194] For example, a PIN-type photodiode can be used as the photoelectric conversion element 308p.

[0195] "Other Structures"

[0196] The input / output device 300 includes a wiring 311 capable of supplying signals. The wiring 311 is provided with a terminal 319. Note that an FPC 309(1) capable of supplying signals such as an image signal or a synchronization signal is electrically connected to the terminal 319.

[0197] Note that a printed wiring board (PWB) can be mounted on the FPC309(1).

[0198] This embodiment can be appropriately combined with other embodiments in this specification.

[0199] Embodiment 4

[0200] In this embodiment, with reference to Figure 7A and 7B and Figures 8A to 8C the structure of the flexible touch screen of the information processor applicable to one embodiment of the present invention will be described.

[0201] Figure 7A and 7B are perspective views showing typical constituent elements of the touch screen of one embodiment of the present invention. Figure 7A is a perspective view of the touch screen 400, Figure 7B is a perspective view showing the constituent elements of the touch screen 400 in a separated state.

[0202] Figures 8A to 8C is a cross-sectional view of the touch screen 400 along the line X1-X2 in Figure 7A .

[0203] The touch screen 400 includes a display unit 401 and a touch sensor 495 (refer to Figure 7B ). Further, the touch screen 400 includes a substrate 410, a substrate 470, and a substrate 490. Note that the substrate 410, the substrate 470, and the substrate 490 are all flexible.

[0204] The display unit 401 includes: a substrate 410; a plurality of pixels on the substrate 410; and a plurality of wirings 411 for supplying signals to the pixels. The plurality of wirings 411 extend to the outer peripheral portion of the substrate 410, and a part of them constitutes a terminal 419. The terminal 419 is electrically connected to the FPC409(1).

[0205] <Touch Sensor>

[0206] The substrate 490 includes a touch sensor 495 and a plurality of wirings 498 electrically connected to the touch sensor 495. The plurality of wirings 498 extend to the outer peripheral portion of the substrate 490, and a part of the plurality of wirings 498 constitutes a terminal. This terminal is electrically connected to the FPC409(2). Note that in Figure 7B , for clarity, the electrodes and wirings of the touch sensor 495 provided on the back side (the side opposite to the observer side) of the substrate 490 are shown by solid lines.

[0207] As the touch sensor 495, a capacitive touch sensor can be used. Examples of capacitive touch sensors are surface capacitive touch sensors and projected capacitive touch sensors.

[0208] Examples of projected capacitive touch sensors are self-capacitive touch sensors and mutual-capacitive touch sensors, which mainly differ in the driving method. Since multiple points can be detected simultaneously, it is preferable to use a mutual-capacitive touch sensor.

[0209] Next, Figure 7B an example of using a projected capacitive touch sensor will be described.

[0210] Note that various sensors capable of detecting the approach or contact of detection objects such as fingers can be used.

[0211] The projected capacitive touch sensor 495 includes electrodes 491 and electrodes 492. The electrode 491 is electrically connected to any one of the plurality of wirings 498, and the electrode 492 is electrically connected to any other one of the plurality of wirings 498.

[0212] As Figure 7A and 7B shown, each of the electrodes 492 has a shape of a plurality of quadrilaterals arranged in a direction connecting one corner of a quadrilateral to one corner of another quadrilateral.

[0213] Each of the electrodes 491 has a rectangular shape and is arranged in a direction intersecting the extending direction of the electrode 492.

[0214] The wiring 494 electrically connects two electrodes 491 between which the electrode 492 is disposed. At this time, it is preferable to minimize the cross-sectional area of the electrode 492 and the wiring 494. By adopting such a structure, the area of the region where no electrode is provided can be reduced, and thus the non-uniformity of the transmittance can be reduced. As a result, the non-uniformity of the brightness of the light from the touch sensor 495 can be reduced.

[0215] Note that the shapes of the electrodes 491 and the electrodes 492 are not limited to the above shapes and can have various shapes. For example, a plurality of electrodes 491 can be arranged in such a way as to minimize the gap between the electrodes 491, and a plurality of electrodes 492 can be provided with an insulating layer sandwiched between the electrodes 491 and the electrodes 492 so that the plurality of electrodes 492 are spaced apart from each other to form a region that does not overlap with the electrodes 491. In this case, it is preferable to provide virtual electrodes that are electrically insulated from these electrodes between two adjacent electrodes 492, whereby the area of the region where the transmittance is different can be reduced.

[0216] Referring to Figures 8A to 8C the structure of the touch sensor 495 will be described.

[0217] The touch sensor 495 includes: a substrate 490; electrodes 491 and 492 disposed on the substrate 490 and configured in a staggered shape; an insulating layer 493 covering the electrodes 491 and 492; and wirings 494 that electrically connect adjacent electrodes 491 to each other.

[0218] The resin layer 497 bonds the substrate 490 and the substrate 470 in such a manner that the touch sensor 495 overlaps with the display unit 401.

[0219] The electrodes 491 and 492 are formed using a transparent conductive material. As the transparent conductive material, conductive oxides such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, or zinc oxide doped with gallium can be used. Note that a film containing graphene can also be used. The film containing graphene can be formed, for example, by reducing a film containing graphene oxide. As a reduction method, a heating method or the like can be employed.

[0220] The electrodes 491 and 492 can be formed by removing unnecessary portions through various patterning techniques such as photolithography after depositing the transparent conductive material on the substrate 490 by sputtering.

[0221] Examples of materials for the insulating layer 493 include resins such as acrylic resin or epoxy resin, resins having a siloxane bond, and inorganic insulating materials such as silicon oxide, silicon oxynitride, and aluminum oxide.

[0222] Furthermore, openings reaching the electrodes 491 are formed in the insulating layer 493, and the wirings 494 electrically connect adjacent electrodes 491. In addition, since the transparent conductive material can increase the aperture ratio of the touch screen, it is suitable for the wirings 494. Also, since a material having higher conductivity than that of the electrodes 491 and 492 can reduce the resistance, it is suitable for the wirings 494.

[0223] One electrode 492 extends in one direction, and a plurality of electrodes 492 are arranged in a stripe shape.

[0224] The wirings 494 cross the electrodes 492.

[0225] The adjacent electrodes 491 are arranged with one electrode 492 interposed therebetween. The wirings 494 electrically connect the adjacent electrodes 491.

[0226] Note that the plurality of electrodes 491 do not necessarily have to be arranged in a direction orthogonal to one electrode 492, and can also be arranged to cross one electrode 492 at an angle less than 90°.

[0227] A wiring 498 is electrically connected to either of the electrodes 491 and 492. A part of the wiring 498 is used as a terminal. The wiring 498 can use, for example, metal materials such as aluminum, gold, platinum, silver, nickel, titanium, tungsten, chromium, molybdenum, iron, cobalt, copper, or palladium, or alloy materials containing the above metal materials.

[0228] Note that an insulating layer covering the insulating layer 493 and the wiring 494 can be provided to protect the touch sensor 495.

[0229] Furthermore, a connection layer 499 electrically connects the wiring 498 to the FPC 409(2).

[0230] As the connection layer 499, various anisotropic conductive films (ACF: Anisotropic Conductive Film) or anisotropic conductive pastes (ACP: Anisotropic Conductive Paste) etc. can be used.

[0231] The resin layer 497 has light transmissivity. For example, a thermosetting resin or an ultraviolet curable resin can be used. Specifically, resins such as acrylic resin, polyurethane resin, epoxy resin, or resins having a siloxane bond can be used.

[0232] <Display unit>

[0233] The display unit 401 includes a plurality of pixels arranged in a matrix. Each pixel includes a display element and a pixel circuit for driving the display element.

[0234] In the present embodiment, an example in which an organic electroluminescent element that emits white light is used as the display element is described. However, the display element is not limited to such an element.

[0235] For example, organic electroluminescent elements that emit different colors of light can be used for each sub-pixel so that each sub-pixel emits different colors of light.

[0236] In addition to the organic electroluminescent element, various display elements such as display elements (electronic ink) that perform display by electrophoresis, electro-fluidic powder, or electro-wetting methods; MEMS shutter display elements; MEMS display elements of the optical interference method; and liquid crystal elements can also be used. Furthermore, the present embodiment can be used for transmissive liquid crystal displays, transflective liquid crystal displays, reflective liquid crystal displays, direct-view liquid crystal displays, etc. In the case of implementing a transflective liquid crystal display or a reflective liquid crystal display, a part or all of the pixel electrodes are used as reflective electrodes. For example, a part or all of the pixel electrodes contain aluminum, silver, etc. In this case, a storage circuit such as an SRAM can be provided under the reflective electrode, thereby reducing power consumption. In addition, a structure suitable for the display element used can be selected from various structures of the pixel circuit.

[0237] In the display section, an active matrix method in which active elements are included in pixels or a passive matrix method in which active elements are not included in pixels can be adopted.

[0238] In the active matrix method, as active elements (nonlinear elements), not only transistors but also various active elements (nonlinear elements) can be used. For example, MIM (Metal Insulator Metal), TFD (Thin Film Diode), etc. can also be used. Since the number of manufacturing processes of these elements is small, the manufacturing cost can be reduced or the yield can be increased. In addition, since the size of these elements is small, the aperture ratio can be increased, so that the power consumption can be reduced or high brightness can be achieved.

[0239] As a method other than the active matrix method, a passive matrix method that does not use active elements (nonlinear elements) can also be adopted. Since active elements (nonlinear elements) are not used, the number of manufacturing processes is small, so that the manufacturing cost can be reduced or the yield can be increased. In addition, since active elements (nonlinear elements) are not used, the aperture ratio can be increased, so that, for example, the power consumption can be reduced or high brightness can be achieved.

[0240] A flexible material can be applied to the substrate 410 and the substrate 470.

[0241] A material that suppresses the unintended transmission of impurities can be applied to the substrate 410 and the substrate 470. For example, a material with a water vapor transmission rate less than or equal to 10 -5 g / m 2 ·day, preferably less than or equal to 10 -6 g / m 2 ·day can be used.

[0242] The substrate 410 can be formed of a material whose linear expansion coefficient is substantially equal to that of the substrate 470. For example, the linear expansion coefficient of this material is preferably less than or equal to 1×10 -3 / K, more preferably less than or equal to 5×10 -5 / K, and further preferably less than or equal to 1×10 -5 / K.

[0243] The substrate 410 is a laminate in which a flexible substrate 410b, a barrier film 410a that prevents unintended impurities from diffusing into the light-emitting element, and a resin layer 410c that bonds the barrier film 410a and the substrate 410b are laminated.

[0244] For example, materials including polyester, polyolefin, polyamide (e.g., nylon, aramid), polyimide, polycarbonate, acrylic resin, polyurethane, epoxy resin, or a resin having a siloxane bond can be used for the resin layer 410c.

[0245] The substrate 470 is a laminate in which a flexible substrate 470b, a barrier film 470a that prevents unintended impurities from diffusing into the light-emitting element, and a resin layer 470c that bonds the barrier film 470a and the substrate 470b are laminated.

[0246] The sealant 460 bonds the substrate 470 and the substrate 410. The sealant 460 has a refractive index higher than that of the atmosphere. When light is extracted to the side of the sealant 460, the sealant 460 is used as an optical adhesive layer. The pixel circuit and the light-emitting element (e.g., the first light-emitting element 450R) are provided between the substrate 410 and the substrate 470.

[0247] 《Structure of Pixel》

[0248] The pixel includes a sub-pixel 402R, and the sub-pixel 402R includes a light-emitting module 480R.

[0249] The sub-pixel 402R includes a first light-emitting element 450R and a pixel circuit including a transistor 402t that can supply power to the first light-emitting element 450R. Furthermore, the light-emitting module 480R includes a first light-emitting element 450R and an optical element (e.g., a first coloring layer 467R).

[0250] The first light-emitting element 450R includes a lower electrode, an upper electrode, and a layer containing a light-emitting organic compound between the lower electrode and the upper electrode.

[0251] The light-emitting module 480R includes a first coloring layer 467R on the light-extracting side.
