[0091] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0095] 5 is a diagram illustrating a configuration of a functional panel that can be used in a data processing device of one embodiment of the present invention, and is a circuit diagram of a pixel circuit 530G(i,j) of the functional panel.

[0096] FIG. 6 is a diagram illustrating the operation of a functional panel that can be used in the information processing device of one embodiment of the present invention.

[0097] <Function panel configuration example 1> The functional panel described in this embodiment has a driving circuit GD, a driving circuit RD, and an area 231 (see FIG. 3A). Note that the area 231 includes an area 231(2) (see FIG. 1A).

[0098] A drive circuit GD supplies a first selection signal, a drive circuit RD supplies a second selection signal and a third selection signal, and the region 231(2) comprises a pixel 703(i,j).

[0099] <<Configuration example 1 of pixel 703(i,j)>> The pixel 703(i,j) includes a pixel circuit 530G(i,j), a light-emitting element 550G(i,j), a pixel circuit 530S(i,j) and a photoelectric conversion element PD(i,j) (see FIGS. 3B and 3C).

[0100] Configuration example 1 of pixel circuit 530G(i,j) The pixel circuit 530G(i,j) is supplied with a first selection signal, and the pixel circuit 530G(i,j) obtains an image signal based on the first selection signal. For example, the first selection signal can be supplied using the conductive film G1(i) (see FIG. 3B). Or, the image signal can be supplied using the conductive film S1g(j).

[0101] The operation of supplying the first selection signal and causing the pixel circuit 530G(i,j) to acquire the image signal can be referred to as "writing" (see FIG. 6).

[0102] Configuration example 1 of light-emitting element 550G(i,j) The light-emitting element 550G(i,j) is electrically connected to the pixel circuit 530G(i,j), and emits light based on an image signal (see FIGS. 3B and 3C).

[0103] The light emitting element 550G(i,j) includes an electrode 551G(i,j) electrically connected to the pixel circuit 530G(i,j) and an electrode 552 electrically connected to the conductive film VCOM2 (see FIGS. 5 and 10A).

[0104] Configuration Example 1 of Pixel Circuit 530S(i,j) The pixel circuit 530S(i,j) is supplied with the second selection signal and the third selection signal during a period when the first selection signal is not supplied (see FIG. 6). The pixel circuit 530S(i,j) acquires an imaging signal based on the second selection signal, and supplies an imaging signal based on the third selection signal. For example, the second selection signal can be supplied using the conductive film TX(i), and the third selection signal can be supplied using the conductive film SE(i) (see FIGS. 3B and 4A).

[0105] The operation of supplying the second selection signal and causing the pixel circuit 530S(i,j) to acquire the imaging signal can be called "imaging" (see FIG. 6). The operation of reading out the imaging signal from the pixel circuit 530S(i,j) can be called "reading out". The operation of supplying a predetermined voltage to the photoelectric conversion element PD(i,j) can be called "initialization", the operation of exposing the initialized photoelectric conversion element PD(i,j) to light for a predetermined period of time can be called "exposure", and the operation of reflecting the voltage changed by exposure to the pixel circuit 530S(i,j) can be called "transfer". In the figure, SRS corresponds to the operation of supplying a reference signal used in the correlated double sampling method, and "output" corresponds to the operation of supplying an imaging signal.

[0106] For example, one frame of image information can be written in 16.7 ms. Specifically, it can operate at a frame rate of 60 Hz. Note that an image signal can be written to the pixel circuit 530G(i,j) in 15.2 μs.

[0107] For example, one frame of image information can be held for a period corresponding to 16 frames, or one frame of imaging information can be captured and read out for a period corresponding to 16 frames.

[0108] Specifically, it can be initialized in 15 μs, exposed in the range of 1 ms to 5 ms, and transferred in 150 μs, or read out in 250 ms.

[0109] <<Configuration example 1 of photoelectric conversion element PD(i,j)>> The photoelectric conversion element PD(i,j) is electrically connected to the pixel circuit 530S(i,j), and the photoelectric conversion element PD(i,j) generates an imaging signal. For example, the photoelectric conversion element PD(2) described in the first embodiment can be used as the photoelectric conversion element PD(i,j).

[0110] This allows imaging during a period when the first selection signal is not being supplied. Or, noise during imaging can be suppressed. Or, imaging signals can be read during a period when the first selection signal is not being supplied. Or, noise during reading can be suppressed. As a result, a novel functional panel that is excellent in convenience, usefulness, and reliability can be provided.

[0111] The photoelectric conversion element PD(i,j) includes an electrode 551S(i,j) electrically connected to the pixel circuit 530S(i,j) and an electrode 552 electrically connected to the conductive film VPD (see FIGS. 4A and 9A). The electrode 552 used in the light-emitting element 550G(i,j) can be used in the photoelectric conversion element PD(i,j). This can simplify the configuration and manufacturing process of the functional panel.

[0112] Configuration example 2 of pixel 703(i,j) A plurality of pixels can be used for pixel 703(i,j). For example, a plurality of pixels that display colors with different hues can be used. Each of the plurality of pixels can be referred to as a sub-pixel. Alternatively, a set of a plurality of sub-pixels can be referred to as a pixel.

[0113] This allows the colors displayed by the multiple pixels to be mixed additively or subtractively, or allows colors of hues that cannot be displayed by individual pixels to be displayed.

[0114] Specifically, pixel 702B(i,j) displaying blue, pixel 702G(i,j) displaying green, and pixel 702R(i,j) displaying red can be used as pixel 703(i,j). Each of pixel 702B(i,j), pixel 702G(i,j), and pixel 702R(i,j) can be referred to as a sub-pixel (see FIG. 7B).

[0115] Also, for example, a pixel displaying white or the like can be used as pixel 703(i,j) in addition to the above set. Also, a pixel displaying cyan, a pixel displaying magenta, and a pixel displaying yellow can be used as pixel 703(i,j).

[0116] Also, for example, a pixel that emits infrared light can be added to the above set and used as pixel 703(g,h) (see FIG. 7C). Specifically, pixel 702N(g,h) that emits light including light having a wavelength of 650 nm or more and 1000 nm or less can be used as pixel 703(g,h).

[0117] <<Configuration Example 3 of Pixel 703(i,j)>> The pixel 703(i,j) is supplied with the second selection signal during a period in which the pixel circuit 530G(i,j) holds an image signal. For example, during a period in which the pixel circuit 530G(i,j) holds an image signal, the pixel 703(i,j) can emit light based on the image signal using the light-emitting element 550G(i,j) (see FIG. 6). Alternatively, after the pixel circuit 530G(i,j) acquires an image signal based on the first selection signal, the pixel circuit 530S(i,j) is supplied with the second selection signal during the period in which the pixel circuit 530G(i,j) is supplied with the first selection signal again.

[0118] This allows the intensity of light emitted by the light emitting element 550G(i,j) to be controlled using the image signal. Alternatively, the subject can be irradiated with light of controlled intensity. Alternatively, the subject can be imaged using the photoelectric conversion element PD(i,j). Alternatively, the subject can be imaged using the photoelectric conversion element PD(i,j) while controlling the intensity of the irradiated light. Alternatively, the effect on the imaging signal caused by the change of the signal held by the pixel circuit 530G(i,j) from one image signal to another image signal can be eliminated. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0119] Configuration example 4 of pixel 703(i,j) The pixel 703(i,j) is supplied with the third selection signal during a period in which the pixel circuit 530G(i,j) holds the one image signal. For example, the pixel circuit 530S(i,j) is supplied with the second selection signal during the period from when the pixel circuit 530G(i,j) acquires the one image signal based on the first selection signal until the pixel circuit 530G(i,j) is supplied with the first selection signal again (see FIG. 6).

[0120] This makes it possible to eliminate the influence on the imaging signal caused by the change in the signal held by the pixel circuit 530G(i,j) from one image signal to another, and as a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0121] <Function panel configuration example 2> A functional panel that can be used in an information processing device according to one embodiment of the present invention includes a conductive film TX(i), a conductive film VR, a conductive film RS(i), a conductive film VCP, a conductive film VPI, a conductive film WX(j), and a conductive film SE(i) (see FIG. 4A). A second selection signal is supplied to the conductive film TX(i), and a third selection signal is supplied to the conductive film SE(i).

[0122] Configuration Example 2 of Pixel Circuit 530S(i,j) The pixel circuit 530S(i,j) includes a switch SW31, a switch SW32, a switch SW33, a transistor M31, a capacitor C31, and a node FD.

[0123] The switch SW31 has a first terminal electrically connected to the photoelectric conversion element PD(i,j), a second terminal electrically connected to the node FD, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film TX(i).

[0124] The switch SW32 has a first terminal electrically connected to the node FD, a second terminal electrically connected to the conductive film VR, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film RS(i).

[0125] The capacitor C31 includes a conductive film electrically connected to the node FD and a conductive film electrically connected to the conductive film VCP.

[0126] The transistor M31 includes a gate electrode electrically connected to the node FD, and a first electrode electrically connected to the conductive film VPI.

[0127] The switch SW33 has a first terminal electrically connected to the second electrode of the transistor M31, a second terminal electrically connected to the conductive film WX(j), and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film SE(i).

[0128] As a result, the imaging signal generated by the photoelectric conversion element PD(i,j) can be transferred to the node FD using the switch SW31. Alternatively, the imaging signal generated by the photoelectric conversion element PD(i,j) can be stored in the node FD using the switch SW31. Alternatively, the pixel circuit 530S(i,j) and the photoelectric conversion element PD(i,j) can be brought into a non-conductive state using the switch SW31. Alternatively, a correlated double sampling method can be applied. Alternatively, noise contained in the imaging signal can be reduced. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0129] <Function panel configuration example 3> A functional panel that can be used in an information processing device of one embodiment of the present invention includes a conductive film G1(i), a conductive film G2(i), a conductive film S1g(j), a conductive film S2g(j), and a conductive film ANO (see FIG. 5). A first selection signal is supplied to the conductive film G1(i). For example, an image signal can be supplied using the conductive film S1g(j). Alternatively, a signal supplied using the conductive film S2g(j) can be added to a signal supplied using the conductive film S1g(j). Note that, for example, an image signal can be supplied in 15.2 μs using the conductive film S1g(j). Alternatively, an image signal can be supplied in 30.4 μs using the conductive film S1g(j) and the conductive film S2g(j).

[0130] Configuration example 2 of pixel circuit 530G(i,j) The pixel circuit 530G(i,j) includes a switch SW21, a switch SW22, a transistor M21, a capacitor C21, and a node N21.

[0131] The transistor M21 includes a gate electrode electrically connected to the node N21, a first electrode electrically connected to the light emitting element 550G(i,j), and a second electrode electrically connected to the conductive film ANO.

[0132] The switch SW21 has a first terminal electrically connected to the node N21, a second terminal electrically connected to the conductive film S1g(j), and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film G1(i).

[0133] The switch SW22 has a first terminal electrically connected to the conductive film S2g(j) and has a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film G2(i).

[0134] The capacitor C21 includes a conductive film electrically connected to the node N21 and a conductive film electrically connected to the second electrode of the switch SW22.

[0135] This allows an image signal to be stored in node N21. Alternatively, the potential of node N21 can be changed using switch SW22. Alternatively, the intensity of light emitted by light-emitting element 550G(i,j) can be controlled using the potential of node N21. As a result, it is possible to provide a novel functional panel that is highly convenient, useful, and reliable.

[0136] <Function panel configuration example 4> A functional panel that can be used in a data processing device according to one embodiment of the present invention includes a conductive film V0 (see FIG. 5).

[0137] Configuration Example 3 of Pixel Circuit 530G(i,j) The pixel circuit 530G(i,j) includes a switch SW23, a node N22, and a capacitor C22.

[0138] The switch SW23 has a first terminal electrically connected to the conductive film V0, a ​​second terminal electrically connected to the node N22, and a function of controlling the conductive state or non-conductive state based on the potential of the conductive film G2(i).

[0139] The capacitor C22 includes a conductive film electrically connected to the node N21 and a conductive film electrically connected to the node N22.

[0140] The first electrode of the transistor M21 is electrically connected to a node N22.

[0141] <Function panel configuration example 5> A functional panel that can be used in a data processing device of one embodiment of the present invention includes a read circuit RC(j), a conductive film VLEN, a conductive film VIV, and a conductive film CL (see FIGS. 3A, 4A, 4B, and 4C).

[0142] 《Example of the configuration of readout circuit RC(j)》 The read circuit RC(j) includes an amplifier circuit and a sampling circuit SC(j) (see FIG. 3A).

[0143] <<Example of amplifier circuit configuration>> The amplifier circuit includes transistor M32(j) (see FIG. 4B).

[0144] The transistor M32(j) includes a gate electrode electrically connected to the conductive film VLEN, a first electrode electrically connected to the conductive film WX(j), and a second electrode electrically connected to the conductive film VIV.

[0145] When the switch SW33 is in a conductive state, the conductive film WX(j) connects the transistor M31(j) and the transistor M32(j) (see FIGS. 4A and 4B). This allows the transistor M31(j) and the transistor M32(j) to form a source follower circuit. Alternatively, the potential of the conductive film WX(j) can be changed based on the potential of the node FD.

[0146] Example of the configuration of sampling circuit SC(j) The sampling circuit SC(j) has a first terminal IN(j), a second terminal, and a third terminal OUT(j) (see FIG. 4C).

[0147] The first terminal is electrically connected to the conductive film WX(j), the second terminal is electrically connected to the conductive film CL, and the third terminal OUT(j) has the function of supplying a signal that changes based on the potential of the first terminal IN(j).

[0148] This makes it possible to obtain an imaging signal from the pixel circuit 530S(i,j). Or, for example, a correlated double sampling method can be applied. Or, a sampling circuit SC(j) can be provided for each conductive film WX(j). A differential signal of the pixel circuit 530S(i,j) can be obtained for each conductive film WX(j). Or, the operating frequency of the sampling circuit SC(j) can be suppressed. Or, noise can be reduced. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0149] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0150] (Embodiment 3) In this embodiment, a structure of a functional panel that can be used in a data processing device of one embodiment of the present invention will be described with reference to FIGS.

[0154] 10A and 10B are diagrams illustrating a structure of a functional panel that can be used in a data processing device of one embodiment of the present invention, and are cross-sectional views of a pixel 702G(i,j) shown in FIG.

[0155] Fig. 11 is a diagram illustrating a configuration of a functional panel that can be used in an information processing device of one embodiment of the present invention, Fig. 11A is a cross-sectional view taken along the cutting lines X1-X2 and X3-X4 in Fig. 7A, and Fig. 11B is a diagram illustrating a part of Fig. 11A.

[0156] <Function panel configuration example 6> A functional panel that can be used in a data processing device according to one embodiment of the present invention includes a functional layer 520 (see FIG. 8).

[0157] Configuration example 1 of functional layer 520 The functional layer 520 includes a pixel circuit 530G(i,j) and a pixel circuit 530S(i,j). The functional layer 520 also includes an opening 591G and an opening 591S.

[0158] The pixel circuit 530G(i,j)G is electrically connected to the light emitting element 550G(i,j) at the opening 591G (see FIG. 8). Also, the pixel circuit 530S(i,j) is electrically connected to the photoelectric conversion element PD(i,j) at the opening 591S.

[0159] For example, the functional layer 520 includes a transistor M21 used in the pixel circuit 530G(i,j) (see FIGS. 5 and 10A) and a transistor used in the switch SW31 of the pixel circuit 530S(i,j) (see FIGS. 4A and 9A).

[0160] This makes it possible to form pixel circuits 530G(i,j) and 530S(i,j) in the functional layer 520. Alternatively, for example, a semiconductor film used in pixel circuit 530S(i,j) can be formed in the process of forming a semiconductor film used in pixel circuit 530G(i,j). Alternatively, the manufacturing process of the functional panel can be simplified. As a result, it is possible to provide a novel functional panel that is highly convenient, useful, or reliable.

[0161] The functional layer 520 also includes a driving circuit GD (see FIGS. 7A and 8). The functional layer 520 includes, for example, a transistor MD used in the driving circuit GD (see FIGS. 8, 11A, and 11B). The functional layer 520 also includes a driving circuit RD and a readout circuit RC (see FIG. 8).

[0162] This makes it possible to form semiconductor films for use in the driving circuit GD, the driving circuit RD, and the readout circuit RC in the process of forming the semiconductor film for use in the pixel circuit 530G(i,j). Alternatively, the manufacturing process of the functional panel can be simplified. As a result, it is possible to provide a novel functional panel that is highly convenient, useful, and reliable.

[0163] Configuration Example 4 of Pixel Circuit 530G(i,j) For example, a bottom-gate transistor or a top-gate transistor can be used in the pixel circuit 530G(i,j). Specifically, a transistor can be used as a switch.

[0164] Configuration Example 3 of Pixel Circuit 530S(i,j) For example, a bottom-gate transistor or a top-gate transistor can be used in the pixel circuit 530S(i,j). Specifically, a transistor can be used as a switch.

[0165] <<Example of transistor configuration>> The transistor includes a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see FIG. 10B). Alternatively, the transistor includes a conductive film 512C and a conductive film 512D (see FIG. 11B). Alternatively, the transistor includes a conductive film 512E and a conductive film 512F (see FIG. 9B).

[0166] The semiconductor film 508 includes a region 508A electrically connected to the conductive film 512A and a region 508B electrically connected to the conductive film 512B. The semiconductor film 508 includes a region 508C between the region 508A and the region 508B.

[0167] The conductive film 504 has a region overlapping with the region 508C, and has a function of a gate electrode.

[0168] The insulating film 506 has a region sandwiched between the semiconductor film 508 and the conductive film 504. The insulating film 506 functions as a gate insulating film.

[0169] The conductive film 512A has either a source electrode function or a drain electrode function, and the conductive film 512B has the other of the source electrode function or the drain electrode function.

[0170] The conductive film 524 can be used for a transistor. The conductive film 524 has a region where the semiconductor film 508 is sandwiched between the conductive film 524 and the conductive film 504. The conductive film 524 functions as a second gate electrode.

[0171] Note that a semiconductor film used for a transistor in a driver circuit can be formed in a process of forming a semiconductor film used for a transistor in a pixel circuit.

[0172] Configuration example 1 of semiconductor film 508 For example, a semiconductor containing a Group 14 element can be used for the semiconductor film 508. Specifically, a semiconductor containing silicon can be used for the semiconductor film 508.

[0173] [Hydrogenated amorphous silicon] For example, hydrogenated amorphous silicon can be used for the semiconductor film 508. Alternatively, microcrystalline silicon or the like can be used for the semiconductor film 508. This makes it possible to provide a functional panel with less display unevenness than, for example, a functional panel using polysilicon for the semiconductor film 508. Alternatively, it is easy to increase the size of the functional panel.

[0174] [Polysilicon] For example, polysilicon can be used for the semiconductor film 508. This allows the field effect mobility of the transistor to be higher than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, the driving capability can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, the aperture ratio of a pixel can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508.

[0175] Alternatively, for example, the reliability of the transistor can be improved as compared to a transistor in which hydrogenated amorphous silicon is used for the semiconductor film 508 .

[0176] Alternatively, the temperature required to manufacture the transistor can be made lower than that of a transistor using single crystal silicon, for example.

[0177] Alternatively, a semiconductor film used for a transistor in a driver circuit can be formed in the same process as a semiconductor film used for a transistor in a pixel circuit. Alternatively, the driver circuit can be formed over the same substrate as the substrate on which the pixel circuit is formed. Alternatively, the number of components included in an electronic device can be reduced.

[0178] [Single crystal silicon] For example, single crystal silicon can be used for the semiconductor film 508. This allows for higher definition than, for example, a functional panel using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, a functional panel with less display unevenness can be provided than, for example, a functional panel using polysilicon for the semiconductor film 508. Alternatively, for example, smart glasses or a head mounted display can be provided.

[0179] Configuration example 2 of semiconductor film 508 For example, metal oxide can be used for the semiconductor film 508. This allows the pixel circuit to hold an image signal for a longer period of time compared to a pixel circuit using a transistor with amorphous silicon in the semiconductor film. Specifically, the selection signal can be supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute while suppressing the occurrence of flicker. As a result, the fatigue accumulated in the user of the information processing device can be reduced. In addition, the power consumption associated with driving can be reduced. In addition, the pixel circuit can hold an image signal for a longer period of time compared to a pixel circuit using a transistor with amorphous silicon in the semiconductor film. Specifically, the second selection signal can be supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. As a result, it is possible to shoot using the global shutter method. In addition, it is possible to shoot a moving subject with reduced distortion.

[0180] For example, an oxide semiconductor can be used for the semiconductor film 508. Specifically, the semiconductor film 508 can be an oxide semiconductor containing indium or an oxide semiconductor containing indium, gallium, and zinc.

[0181] For example, a transistor having a smaller leakage current in an off state than a transistor using amorphous silicon for a semiconductor film can be used. Specifically, a transistor using an oxide semiconductor for a semiconductor film can be used as a switch or the like. This allows the potential of a floating node to be held for a longer time than a circuit using a transistor using amorphous silicon for a switch.

[0182] For example, a 25 nm thick film containing indium, gallium and zinc can be used for the semiconductor film 508 .

[0183] For example, a conductive film in which a 10-nm-thick film containing tantalum and nitrogen and a 300-nm-thick film containing copper are stacked can be used as the conductive film 504. Note that the film containing copper has a region in which the film containing tantalum and nitrogen is sandwiched between the insulating film 506 and the copper-containing film.

[0184] For example, a stacked film in which a 400-nm-thick film containing silicon and nitrogen and a 200-nm-thick film containing silicon, oxygen, and nitrogen are stacked can be used as the insulating film 506. Note that the film containing silicon and nitrogen has a region in which the film containing silicon, oxygen, and nitrogen is sandwiched between the semiconductor film 508 and the film containing silicon and nitrogen.

[0185] For example, a conductive film in which a 50-nm-thick film containing tungsten, a 400-nm-thick film containing aluminum, and a 100-nm-thick film containing titanium are stacked in this order can be used as the conductive film 512A or the conductive film 512B. Note that the film containing tungsten has a region in contact with the semiconductor film 508.

[0186] Incidentally, for example, a manufacturing line for bottom-gate transistors using amorphous silicon as a semiconductor can be easily modified to a manufacturing line for bottom-gate transistors using an oxide semiconductor as a semiconductor. Also, for example, a manufacturing line for top-gate transistors using polysilicon as a semiconductor can be easily modified to a manufacturing line for top-gate transistors using an oxide semiconductor as a semiconductor. Either modification can effectively utilize the existing manufacturing line.

[0187] This makes it possible to suppress flickering. Or, it makes it possible to reduce power consumption. Or, it makes it possible to display fast-moving videos smoothly. Or, it makes it possible to display photographs and the like with a rich range of gradations. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

This makes it possible to manufacture a large display device.

[0227] An organic material, an inorganic material, or a composite material such as an organic material and an inorganic material can be used for the substrate 510 or the substrate 770 .

[0228] For example, inorganic materials such as glass, ceramics, and metals can be used. Specifically, alkali-free glass, soda-lime glass, potash glass, crystal glass, aluminosilicate glass, tempered glass, chemically strengthened glass, quartz, sapphire, or the like can be used for the substrate 510 or substrate 770. Alternatively, aluminosilicate glass, tempered glass, chemically strengthened glass, sapphire, or the like can be suitably used for the substrate 510 or substrate 770 disposed on the side of the functional panel closer to the user. This can prevent the functional panel from being damaged or scratched during use.

[0229] Specifically, an inorganic oxide film, an inorganic nitride film, an inorganic oxynitride film, etc. can be used. For example, a silicon oxide film, a silicon nitride film, a silicon oxynitride film, an aluminum oxide film, etc. can be used. Stainless steel, aluminum, etc. can be used for the substrate 510 or the substrate 770.

[0230] For example, a single crystal semiconductor substrate made of silicon or silicon carbide, a polycrystalline semiconductor substrate, a compound semiconductor substrate such as silicon germanium, an SOI substrate, or the like can be used for the base material 510 or the base material 770. This allows a semiconductor element to be formed on the base material 510 or the base material 770.

[0231] For example, organic materials such as resin, resin film, or plastic can be used for the substrate 510 or substrate 770. Specifically, materials including polyester, polyolefin, polyamide (nylon, aramid, etc.), polyimide, polycarbonate, polyurethane, or acrylic resin, epoxy resin, or resin having a siloxane bond such as silicone can be used for the substrate 510 or substrate 770. For example, resin films, resin plates, laminated materials, etc. including these materials can be used. This can reduce the weight. Or, for example, the frequency of occurrence of breakage due to dropping can be reduced.

[0232] Specifically, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), cycloolefin polymer (COP), cycloolefin copolymer (COC), or the like can be used for the substrate 510 or substrate 770 .

[0233] For example, a composite material in which a metal plate, a thin glass plate, or a film of an inorganic material or the like is bonded to a resin film or the like can be used for the substrate 510 or the substrate 770. For example, a composite material in which fibrous or particulate metal, glass, inorganic material, or the like is dispersed in a resin can be used for the substrate 510 or the substrate 770. For example, a composite material in which fibrous or particulate resin, organic material, or the like is dispersed in an inorganic material can be used for the substrate 510 or the substrate 770.

[0234] Furthermore, a single layer material or a material having multiple layers laminated thereon can be used for the substrate 510 or substrate 770. For example, a material having an insulating film or the like laminated thereon can be used. Specifically, a material having one or more films selected from a silicon oxide layer, a silicon nitride layer, a silicon oxynitride layer, or the like laminated thereon can be used. This can prevent, for example, the diffusion of impurities contained in the substrate. Alternatively, it can prevent the diffusion of impurities contained in glass or resin. Alternatively, it can prevent the diffusion of impurities that permeate the resin.

[0235] Also, paper or wood may be used for the substrate 510 or substrate 770 .

[0236] For example, a material having a heat resistance sufficient to withstand heat treatment during the manufacturing process can be used for the base material 510 or the base material 770. Specifically, a material having a heat resistance sufficient to withstand heat applied during a manufacturing process in which a transistor, a capacitor, or the like is directly formed can be used for the base material 510 or the base material 770.

[0237] For example, a method can be used in which an insulating film, a transistor, a capacitor, or the like is formed on a process substrate that has heat resistance to heat applied during the manufacturing process, and the formed insulating film, transistor, capacitor, or the like is transferred to, for example, the base material 510 or the base material 770. In this way, for example, an insulating film, a transistor, a capacitor, or the like can be formed on a substrate that has flexibility.

[0238] "Sealing material 705" The sealing material 705 has an area sandwiched between the functional layer 520 and the base material 770, and has a function of bonding the functional layer 520 and the base material 770 together (see FIG. 10A).

[0239] The sealing material 705 can be an inorganic material, an organic material, or a composite material of an inorganic material and an organic material.

[0240] For example, the sealant 705 can be made of an organic material such as a heat-meltable resin or a curable resin.

[0241] For example, the sealant 705 may be made of an organic material such as a reaction curing adhesive, a photocuring adhesive, a heat curing adhesive, and / or an anaerobic adhesive.

[0242] Specifically, adhesives containing epoxy resin, acrylic resin, silicone resin, phenol resin, polyimide resin, imide resin, PVC (polyvinyl chloride) resin, PVB (polyvinyl butyral) resin, EVA (ethylene vinyl acetate) resin, etc. can be used for the sealing material 705.

[0244] <Functional Layer 720> The functional layer 720 includes a light-shielding film BM and an insulating film 771 .

[0245] 《Light blocking film BM》 The light-shielding film BM has an opening in an area overlapping with the pixel 702G(i,j). The light-shielding film BM also has an opening in an area overlapping with the pixel 702S(i,j). For example, a dark-colored material can be used for the light-shielding film BM. This can improve the contrast of the display.

[0246] "Insulating Film 771" The insulating film 771 has a region sandwiched between the base material 770 and the light-shielding film BM.

[0247] 《Structure KB》 The structural body KB has a region sandwiched between the functional layer 520 and the base material 770. In addition, the structural body KB has a function of providing a predetermined gap between the functional layer 520 and the base material 770.

[0249] 《Functional membrane 770P, etc.》 The functional film 770P has a region that overlaps with the light emitting element 550G(i,j).

[0250] For example, an anti-reflection film, a polarizing film, a retardation film, a light diffusing film, a light collecting film, or the like can be used for the functional film 770P.

[0251] For example, an anti-reflection film having a thickness of 1 μm or less can be used for the functional film 770P. Specifically, a laminated film having three or more dielectric layers, preferably five or more dielectric layers, more preferably fifteen or more dielectric layers can be used for the functional film 770P. This makes it possible to suppress the reflectance to 0.5% or less, preferably 0.08% or less.

[0252] For example, a circularly polarizing film can be used for the functional film 770P.

[0253] In addition, the functional film 770P can be used with antistatic films that prevent dust from sticking, water-repellent films that make it difficult for dirt to adhere, oil-repellent films that make it difficult for dirt to adhere, anti-reflection films, non-glossy films (anti-glare films), hard coat films that prevent scratches from occurring during use, and self-repairing films that repair any scratches that do occur.

[0254] <Configuration example 5 of function panel 700> In addition, functional panel 700 has insulating film 528 and insulating film 573 (see FIG. 10A).

[0255] "Insulating Film 528" The insulating film 528 has a region sandwiched between the functional layer 520 and the base material 770, and the insulating film 528 has an opening in a region overlapping with the light emitting element 550G(i,j) (see FIG. 10A).

[0256] For example, the same material as that used for the insulating film 521 can be used for the insulating film 528. Specifically, the insulating film 528 can be a silicon oxide film, a film containing an acrylic resin, a film containing polyimide, or the like.

[0257] "Insulating Film 573" The insulating film 573 has a region that sandwiches the light emitting element 550G(i,j) between itself and the functional layer 520 (see FIG. 10A).

[0258] For example, a single film or a stacked film in which multiple films are stacked can be used for the insulating film 573. Specifically, a stacked film in which an insulating film 573A that can be formed by a method that is unlikely to damage the light-emitting element 550G(i,j) and a dense insulating film 573B with few defects are stacked can be used for the insulating film 573. This can suppress diffusion of impurities into the light-emitting element 550G(i,j). Alternatively, the reliability of the light-emitting element 550G(i,j) can be improved.

[0259] Configuration example 2 of light-emitting element 550G(i,j) An organic electroluminescence element, an inorganic electroluminescence element, a light-emitting diode, a QDLED (Quantum Dot LED), or the like can be used for the light-emitting element 550G(i,j) (see FIG. 10A).

[0260] For example, the electrode 551G(i,j), the electrode 552, and the layer 553G(j) containing a light-emitting material can be used for the light-emitting element 550G(i,j). The layer 553G(j) containing a light-emitting material has a region sandwiched between the electrode 551G(i,j) and the electrode 552.

[0261] Configuration Example 1 of Layer 553G(j) Containing a Luminescent Material For example, a laminate material can be used for layer 553G(j) that includes the luminescent material.

[0262] For example, blue light emitting material, green light emitting material, red light emitting material, infrared light emitting material, or ultraviolet light emitting material can be used for layer 553G(j) containing luminescent material.

[0263] Configuration Example 2 of Layer 553G(j) Containing a Luminescent Material For example, a layer of material laminated to emit white light may be used for layer 553G(j) containing the luminescent material.

[0264] Specifically, a plurality of materials that emit light with different hues can be used for layer 553G(j) containing a light-emitting material.

[0265] For example, a laminated material in which a layer including a light-emitting material including a fluorescent material that emits blue light and a layer including a material other than the fluorescent material that emits green and red light are laminated can be used for the layer including the light-emitting material 553G(j). Alternatively, a laminated material in which a layer including a light-emitting material including a fluorescent material that emits blue light and a layer including a material other than the fluorescent material that emits yellow light are laminated can be used for the layer including the light-emitting material 553G(j).

[0266] For example, a colored film CF may be laminated on the layer 553G(j) containing a light-emitting material, which allows light of a predetermined hue to be extracted from white light.

[0267] Configuration Example 3 of Layer 553G(j) Containing a Luminescent Material For example, a laminated material that is laminated so as to emit blue light or ultraviolet light can be used for the layer 553G(j) containing a light-emitting material. Also, for example, a color conversion layer CC can be used by being laminated.

[0268] Configuration Example 4 of Layer 553G(j) Containing a Luminescent Material The layer 553G(j) containing a light-emitting material includes a light-emitting unit. The light-emitting unit includes one region where electrons injected from one side recombine with holes injected from the other side. The light-emitting unit includes a light-emitting material, and the light-emitting material emits energy generated by the recombination of electrons and holes as light. A hole transport layer and an electron transport layer can be used for the light-emitting unit. The hole transport layer is disposed closer to the positive electrode than the electron transport layer, and the hole transport layer has a higher hole mobility than the electron transport layer.

[0269] For example, a plurality of light-emitting units and an intermediate layer can be used in the layer 553G(j) containing a light-emitting material. The intermediate layer has a region sandwiched between two light-emitting units. The intermediate layer has a charge generating region, and has a function of supplying holes to the light-emitting unit arranged on the cathode side and supplying electrons to the light-emitting unit arranged on the anode side. A configuration having a plurality of light-emitting units and an intermediate layer is sometimes called a tandem-type light-emitting element.

[0270] This makes it possible to increase the current efficiency relating to light emission, or to reduce the current density flowing through the light emitting element at the same luminance, or to increase the reliability of the light emitting element.

[0271] For example, a light-emitting unit including a material that emits light of one hue can be stacked with a light-emitting unit including a material that emits light of another hue to be used in the layer 553G(j) including the light-emitting material. Alternatively, a light-emitting unit including a material that emits light of one hue can be stacked with a light-emitting unit including a material that emits light of the same hue to be used in the layer 553G(j) including the light-emitting material. Specifically, two light-emitting units including a material that emits blue light can be stacked.

[0272] Incidentally, for example, high molecular weight compounds (oligomers, dendrimers, polymers, etc.), medium molecular weight compounds (compounds in the intermediate range between low molecular weight and high molecular weight: molecular weight 400 or more and 4000 or less), etc. can be used in layer 553G(j) containing a light-emitting material.

[0273] 《Electrode 551G(i,j), Electrode 552》 For example, a material that can be used for a wiring or the like can be used for the electrode 551G(i,j) or the electrode 552. Specifically, a material that transmits visible light can be used for the electrode 551G(i,j) or the electrode 552.

[0274] For example, a conductive oxide or a conductive oxide containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide with gallium added, or the like can be used. Alternatively, a metal film that is thin enough to transmit light can be used. Alternatively, a material that transmits visible light can be used.

[0275] For example, a metal film that transmits part of light and reflects the other part of light can be used for the electrode 551G(i,j) or the electrode 552. For example, a layer 553G(j) containing a light-emitting material is used to adjust the distance between the electrode 551G(i,j) and the electrode 552.

[0276] This allows a microresonator structure to be provided in the light emitting element 550G(i,j). Alternatively, light of a specific wavelength can be extracted more efficiently than other light. Alternatively, light with a narrow half-width spectrum can be extracted. Alternatively, light of a vivid color can be extracted.

[0277] For example, a film that efficiently reflects light can be used for the electrode 551G(i,j) or the electrode 552. Specifically, a material containing silver, palladium, or the like or a material containing silver, copper, or the like can be used for the metal film.

[0278] Furthermore, the electrode 551G(i,j) is electrically connected to the pixel circuit 530G(i,j) through the opening 591G (see FIG. 9A). The electrode 551G(i,j) overlaps, for example, an opening formed in the insulating film 528, and the electrode 551G(i,j) has the insulating film 528 on its periphery.

[0279] This makes it possible to prevent a short circuit between electrode 551G(i,j) and electrode 552.

[0280] <<Configuration example 1 of photoelectric conversion element PD(i,j)>> Photoelectric conversion element PD(i,j) includes an electrode 551S(i,j), an electrode 552, and a layer 553S(j) including a photoelectric conversion material (see FIG. 9A).

[0281] For example, a heterojunction type photoelectric conversion element, a bulk heterojunction type photoelectric conversion element, or the like can be used as the photoelectric conversion element PD(i,j).

[0282] [Configuration example 1 of layer 553S(j) containing photoelectric conversion material] For example, a laminated film in which a p-type semiconductor film and an n-type semiconductor film are laminated so as to be in contact with each other can be used for the layer 553S(j) containing a photoelectric conversion material. Note that a photoelectric conversion element PD(i,j) using such a laminated film structure for the layer 553S(j) containing a photoelectric conversion material can be called a PN-type photodiode.

[0283] For example, a laminated film in which a p-type semiconductor film, an i-type semiconductor film, and an n-type semiconductor film are laminated so that an i-type semiconductor film is sandwiched between a p-type semiconductor film and an n-type semiconductor film can be used for the layer 553S(j) containing a photoelectric conversion material. Note that a photoelectric conversion element PD(i,j) using a laminated film of such a structure for the layer 553S(j) containing a photoelectric conversion material can be called a PIN-type photodiode.

[0284] For example, a laminated film in which a p+ type semiconductor film, a p- type semiconductor film, a p type semiconductor film, and an n type semiconductor film are laminated so that a p- type semiconductor film is sandwiched between a p+ type semiconductor film and an n type semiconductor film, and a p type semiconductor film is sandwiched between the p- type semiconductor film and the n type semiconductor film, can be used for the layer 553S(j) containing a photoelectric conversion material. Note that a photoelectric conversion element PD(i,j) using a laminated film of such a structure for the layer 553S(j) containing a photoelectric conversion material can be called an avalanche photodiode.

[0285] [Configuration example 2 of layer 553S(j) containing photoelectric conversion material] For example, a semiconductor containing a group 14 element can be used for the layer 553S(j) containing the photoelectric conversion material. Specifically, a semiconductor containing silicon can be used for the layer 553S(j) containing the photoelectric conversion material. For example, hydrogenated amorphous silicon, microcrystalline silicon, polysilicon, single crystal silicon, or the like can be used for the layer 553S(j) containing the photoelectric conversion material.

[0286] For example, an organic semiconductor can be used for the layer 553S(j) containing a photoelectric conversion material. Specifically, a part of a layer used for the layer 553G(j) containing a light-emitting material can be used for a part of the layer 553S(j) containing a photoelectric conversion material.

[0287] Specifically, the hole transport layer and the electron transport layer used for the layer 553G(j) containing a light-emitting material can be used for the layer 553S(j) containing a photoelectric conversion material, thereby simplifying the manufacturing process.

[0288] Also, for example, fullerenes (e.g., C 60 , C 70 An electron-accepting organic semiconductor material such as ZnO, ZnSe, etc. or a derivative thereof can be used for the n-type semiconductor film.

[0289] Furthermore, for example, an electron-donating organic semiconductor material such as copper(II) phthalocyanine (CuPc) or tetraphenyldibenzoperiflanthene (DBP) can be used for the p-type semiconductor film.

[0290] Also, for example, a film obtained by co-evaporating an electron-accepting semiconductor material and an electron-donating semiconductor material can be used as the i-type semiconductor film.

[0291] <<Configuration Example 1 of Area 231>> Region 231 comprises a group of pixels 703(i,1) through 703(i,n) and another group of pixels 703(1,j) through 703(m,j) (see FIG. 3A).

[0292] A group of pixels 703(i,1) to 703(i,n) are arranged in the row direction (the direction indicated by arrow R1 in the figure), and the group of pixels 703(i,1) to 703(i,n) includes pixel 703(i,j).

[0293] In addition, the conductive film G1(i) is electrically connected to the group of pixels 703(i,1) to 703(i,n), and the group of pixels 703(i,1) to 703(i,n) is electrically connected to the conductive film TX(i).

[0294] Another group of pixels 703(1,j) to 703(m,j) are arranged in a column direction (the direction indicated by the arrow C1 in the figure) that intersects the row direction, and the other group of pixels 703(1,j) to 703(m,j) includes pixel 703(i,j).

[0295] In addition, another group of pixels 703(1,j) to pixels 703(m,j) are electrically connected to the conductive film S1g(j), and another group of pixels 703(1,j) to pixels 703(m,j) are electrically connected to the conductive film WX(j).

[0296] This makes it possible to obtain imaging information from a plurality of pixels, or to supply image information to a plurality of pixels, thereby providing a novel functional panel that is highly convenient, useful, and reliable.

[0297] <<Configuration Example 2 of Area 231>> Region 231 comprises region 231(1), and region 231(1) comprises pixel 703(g,h) (see Figures 1A and 7A).

[0298] Pixel 703(g,h) includes light-emitting element 550(1) (see FIGS. 2C and 2D). Specifically, pixel 702B(g,h) that displays blue, pixel 702G(g,h) that displays green, pixel 702R(g,h) that displays red, and pixel 702N(g,h) that includes light-emitting element 550(1) can be used for pixel 703(g,h) (see FIGS. 2C and 7C).

[0299] <Function panel configuration example 7> A functional panel that can be used in a data processing device of one embodiment of the present invention includes a multiplexer MUX, an amplifier circuit AMP, and an analog-to-digital conversion circuit ADC (see FIG. 3A).

[0300] The multiplexer MUX has a function of selecting one of the multiple sampling circuits SC(j) to obtain an image signal and supplying it to, for example, an amplifier circuit AMP.

[0301] Specifically, it is electrically connected to the third terminal OUT(1) of the sampling circuit SC(1) through the third terminal OUT(9) of the sampling circuit SC(9), and can acquire an imaging signal from a specified sampling circuit and supply it to the amplifier circuit AMP.

[0302] This makes it possible to acquire imaging information by selecting a predetermined pixel from a plurality of pixels arranged in the row direction. Alternatively, the number of imaging signals acquired simultaneously can be suppressed to a predetermined number. Alternatively, an analog-to-digital conversion circuit ADC having a smaller number of input channels than the number of pixels arranged in the row direction can be used. As a result, a novel functional panel that is excellent in convenience, usefulness, and reliability can be provided.

[0303] The amplifier circuit AMP can amplify the image signal and supply it to the analog-to-digital conversion circuit ADC.

[0304] The functional layer 520 includes a multiplexer MUX and an amplifier circuit AMP.

[0305] This makes it possible to form a semiconductor film used in the multiplexer MUX and the amplifier circuit AMP in the process of forming a semiconductor film used in the pixel circuit 530G(i,j), for example. Alternatively, the manufacturing process of the functional panel can be simplified. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0306] The analog-to-digital conversion circuit ADC has a function of converting an analog image signal into a digital signal.

[0307] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0308] (Embodiment 4) In this embodiment, a structure of a functional panel that can be used in a data processing device of one embodiment of the present invention will be described with reference to FIGS.

[0309] 12A to 12D are diagrams illustrating a configuration of a display device according to one embodiment of the present invention, in which FIG 12A is a block diagram of a display device according to one embodiment of the present invention, and FIG 12B to FIG 12D are projection views illustrating an external appearance of the display device according to one embodiment of the present invention.

[0310] <Example of display device configuration> The display device described in this embodiment has a functional panel 700 and a control unit 238 (see FIG. 12A).

[0311] Configuration example 1 of the control unit 238 The control unit 238 is supplied with image information VI and control information CI, which may for example be a clock signal or a timing signal.

[0312] The control unit 238 generates information V11 based on the image information VI, and generates a control signal based on the control information CI, and also supplies the information V11 and the control signal.

[0313] For example, the information V11 includes a gradation of 8 bits or more, preferably 12 bits or more. Also, for example, a clock signal or a start pulse of a shift register used in a driving circuit can be used as a control signal.

[0314] <<Configuration Example 2 of the Control Unit 238>> For example, the decompression circuit 234 and the image processing circuit 235 can be used in the control unit 238 .

[0315] 《Extension circuit 234》 The decompression circuit 234 has a function of decompressing the image information VI that is supplied in a compressed state. The decompression circuit 234 has a storage unit. The storage unit has a function of storing, for example, the decompressed image information.

[0316] "Image processing circuit 235" The image processing circuit 235 includes, for example, a storage area. The storage area has a function of storing information included in the image information VI, for example.

[0317] The image processing circuit 235 has, for example, a function of correcting the image information VI based on a predetermined characteristic curve to generate information V11, and a function of supplying the information V11.

[0318] <<Function panel configuration example 1>> Information V11 and a control signal are supplied to the functional panel 700. For example, the functional panel 700 described in the second or third embodiment can be used.

[0319] Configuration Example 5 of Pixel 703(i,j) The pixel 703(i,j) emits light based on the information V11. The pixel 703(g,h) also emits light based on the information V11.

[0320] This allows image information to be displayed using the display element. Alternatively, light can be emitted from the light-emitting element 550(1) using the image information. As a result, a novel display device with excellent convenience, usefulness, or reliability can be provided. Alternatively, for example, a smart watch (see FIG. 12B), a video monitor (see FIG. 12C), or a notebook computer (see FIG. 12D) can be provided.

[0321] <<Function panel configuration example 2>> For example, the functional panel 700 includes a driving circuit and a control circuit (see FIG. 12A).

[0322] <Drive circuit> The drive circuits operate based on a control signal, and the operation of multiple drive circuits can be synchronized using the control signal.

[0323] For example, the driving circuit GD can be used in the functional panel 700. The driving circuit GD is supplied with a control signal and has a function of supplying a first selection signal.

[0324] Also, for example, the driving circuit SD can be used in the functional panel 700. The driving circuit SD is supplied with a control signal and information V11 and can supply an image signal.

[0325] Also, for example, the driving circuit RD can be used in the functional panel 700. The driving circuit RD is supplied with a control signal and can supply a second selection signal.

[0326] Also, for example, a readout circuit RC can be used in the functional panel 700. The readout circuit RC is supplied with a control signal and can read out an image signal using, for example, a correlated double sampling method.

[0327] <<Control circuit 243>> The control circuit 243 has a function of generating and supplying a control signal. For example, a clock signal or a timing signal can be used as the control signal.

[0328] Specifically, a control circuit formed on a rigid substrate can be used for the functional panel, or a control circuit formed on a rigid substrate can be electrically connected to the control unit 238 using a flexible printed circuit board.

[0329] <<Control circuit 233>> For example, a timing controller can be used in the control circuit 233 .

[0330] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0331] (Embodiment 5) In this embodiment, a structure of an input / output device of one embodiment of the present invention will be described with reference to FIG.

[0332] FIG. 13 is a block diagram illustrating a configuration of an input / output device of one embodiment of the present invention.

[0333] <Example 1 of I / O device configuration> The input / output device described in this embodiment includes an input unit 240 and a display unit 230 (see FIG. 13).

[0334] Configuration example of display unit 230 Display unit 230 includes a functional panel. For example, functional panel 700 described in embodiment 2 or 3 can be used for display unit 230. A configuration having input unit 240 and display unit 230 can be referred to as an input / output panel 700TP.

[0335] Example of configuration of input unit 240 The input unit 240 has a detection area 241. The input unit 240 has a function of detecting an object approaching the detection area 241.

[0336] Furthermore, the detection region 241 includes an area that overlaps with pixel 703(i,j).

[0337] This makes it possible to detect an object that is close to an area overlapping with the display unit while displaying image information using the display unit. Alternatively, position information can be input using a finger or the like that is brought close to the display unit as a pointer. Alternatively, position information can be associated with image information displayed on the display unit. As a result, it is possible to provide a novel input / output device that is highly convenient, useful, and reliable.

[0338] Configuration example 1 of detection area 241 The sensing area 241 may, for example, include one or more detectors.

[0339] The detection region 241 has a group of detectors 802(g,1) through 802(g,q) and another group of detectors 802(1,h) through 802(p,h), where g is an integer between 1 and p, h is an integer between 1 and q, and p and q are integers greater than or equal to 1.

[0340] A group of detectors 802(g,1) to 802(g,q) includes a detector 802(g,h) and is arranged in a row direction (the direction indicated by the arrow R2 in the figure). Note that the direction indicated by the arrow R2 may be the same as the direction indicated by the arrow R1, or may be different.

[0341] Another group of detectors 802(1,h) to 802(p,h) includes a detector 802(g,h) and is arranged in a column direction (the direction indicated by the arrow C2 in the figure) that intersects with the row direction.

[0342] Detector The detector has a function of detecting a nearby pointer. For example, a finger or a stylus pen can be used as the pointer. For example, a metal piece or a coil can be used as the stylus pen.

[0343] Specifically, a capacitance type proximity sensor, an electromagnetic induction type proximity sensor, an optical type proximity sensor, a resistive film type proximity sensor, or the like can be used as the detector.

[0344] Furthermore, detectors of multiple types can be used in combination. For example, a detector for detecting a finger and a detector for detecting a stylus pen can be used in combination.

[0345] This makes it possible to determine the type of pointer. Alternatively, different commands can be associated with the detection information based on the determined type of pointer. Specifically, if it is determined that a finger is used as the pointer, the detection information can be associated with a gesture. Alternatively, if it is determined that a stylus pen is used as the pointer, the detection information can be associated with a drawing process.

[0346] Specifically, a finger can be detected using a capacitance type, a pressure sensitive type, or an optical type proximity sensor, or a stylus pen can be detected using an electromagnetic induction type or an optical type proximity sensor.

[0347] Configuration example 2 of input unit 240 The input section 240 comprises an oscillator circuit OSC and a detection circuit DC (see FIG. 13).

[0348] The oscillator circuit OSC supplies a search signal to the detector 802(g,h). For example, a square wave, a sawtooth wave, a triangular wave, a sine wave, etc. can be used as the search signal.

[0349] The detector 802(g,h) generates and provides a detection signal that varies based on the distance to the pointer proximate to the detector 802(g,h) and the probe signal.

[0350] The detection circuit DC provides input information based on the detection signal.

[0351] This makes it possible to detect the distance from the approaching pointer to the detection area 241. Alternatively, it makes it possible to detect the position within the detection area 241 to which the pointer is closest.

[0352] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0356] Fig. 16 is a diagram illustrating a program according to one embodiment of the present invention. Fig. 16A is a flowchart illustrating interrupt processing of a program according to one embodiment of the present invention. Fig. 16B is a schematic diagram illustrating the operation of an information processing device, and Fig. 16C is a timing chart illustrating the operation of the information processing device according to one embodiment of the present invention.

[0357] <Configuration example 1 of information processing device> The information processing device described in this embodiment includes an arithmetic device 210 and an input / output device 220 (see FIG. 14A). The input / output device 220 is electrically connected to the arithmetic device 210. The information processing device 200 may include a housing (see FIGS. 14B and 14C).

[0358] Configuration Example 1 of the Calculation Device 210 The arithmetic unit 210 is supplied with input information II or sensed information DS. The arithmetic unit 210 generates control information CI and image information VI based on the input information II or sensed information DS, and supplies the control information CI and image information VI.

[0359] The arithmetic device 210 includes a calculation unit 211 and a storage unit 212. The arithmetic device 210 also includes a transmission path 214 and an input / output interface 215.

[0360] The transmission path 214 is electrically connected to the calculation unit 211 , the storage unit 212 , and the input / output interface 215 .

[0361] 《Arithmetic section 211》 The calculation unit 211 has a function of executing a program, for example.

[0362] 《Storage section 212》 The storage unit 212 has a function of storing, for example, the program executed by the calculation unit 211, initial information, setting information, images, and the like.

[0363] Specifically, a hard disk, a flash memory, a memory including a transistor including an oxide semiconductor, or the like can be used.

[0364] Input / output interface 215, transmission path 214 The input / output interface 215 includes a terminal or wiring and has a function of supplying information and receiving information. For example, the input / output interface 215 can be electrically connected to the transmission path 214. The input / output interface 215 can also be electrically connected to the input / output device 220.

[0365] The transmission path 214 includes wiring and has a function of supplying information and receiving information. For example, the transmission path 214 can be electrically connected to the input / output interface 215. The transmission path 214 can also be electrically connected to the calculation unit 211, the storage unit 212, or the input / output interface 215.

[0366] Example of the configuration of the input / output device 220 The input / output device 220 supplies input information II and sensed information DS. The input / output device 220 is supplied with control information CI and image information VI (see FIG. 14A).

[0367] For example, keyboard scan code, position information, button operation information, audio information, image information, etc. can be used as the input information II. Alternatively, for example, illuminance information, posture information, acceleration information, direction information, pressure information, temperature information, humidity information, etc. of the environment in which the information processing device 200 is used can be used as the detection information DS.

[0368] For example, a signal for controlling the luminance, saturation, or hue of the image information VI may be used as the control information CI, or a signal for changing the display of a part of the image information VI may be used as the control information CI.

[0369] The input / output device 220 includes a display unit 230, an input unit 240, and a detection unit 250. For example, the input / output device described in the fifth embodiment can be used for the input / output device 220. The input / output device 220 can also include a communication unit 290.

[0370] Configuration example of display unit 230 The display unit 230 displays the image information VI based on the control information CI.

[0371] The display unit 230 includes a control unit 238, a driving circuit GD, a driving circuit SD, and a functional panel 700 (see FIG. 12). For example, the display device described in the fourth embodiment can be used for the display unit 230.

[0372] Example of configuration of input unit 240 The input unit 240 generates input information II. For example, the input unit 240 has a function of supplying position information P1.

[0373] For example, a human interface or the like can be used for the input unit 240 (see FIG. 14A). Specifically, a keyboard, a mouse, a touch sensor, a microphone, a camera, or the like can be used for the input unit 240.

[0374] It is also possible to use a touch sensor having an area overlapping with the display unit 230. Note that an input / output device including the display unit 230 and a touch sensor having an area overlapping with the display unit 230 can be called a touch panel or a touch screen.

[0375] For example, a user can perform various gestures (such as tapping, dragging, swiping, or pinching in) using a finger that touches the touch panel as a pointer.

[0376] For example, the computing device 210 can analyze information such as the position or trajectory of a finger touching the touch panel, and when the analysis result satisfies a predetermined condition, it can determine that a predetermined gesture has been provided. This allows the user to provide a predetermined operation command that is previously associated with a predetermined gesture by using the gesture.

[0377] As one example, a user can provide a "scroll command" to change the displayed position of image information by using a gesture of moving a finger in contact with the touch panel along the touch panel.

[0378] The user can also provide a "drag command" to pull out and display the navigation panel NP at the edge of the area 231 by using a gesture of moving a finger in contact with the edge of the area 231 (see FIG. 14C). The user can also provide a "leaf-through command" to flip through the index image IND, parts of other pages, or thumbnail images TN of other pages in a predetermined order on the navigation panel NP by using a gesture of moving the position where the finger is pressed firmly, or by using the pressure of the finger. This allows the user to turn the pages of the electronic book terminal as if flipping through the pages of a paper book. Or, the user can search for a predetermined page by relying on the thumbnail image TN or the index image IND.

[0379] Example of configuration of detection unit 250 The detection unit 250 generates detection information DS. For example, the detection unit 250 has a function of detecting the illuminance of the environment in which the information processing device 200 is used, and a function of supplying the illuminance information.

[0380] The detection unit 250 has a function of detecting the surrounding state and supplying detection information, specifically, illuminance information, attitude information, acceleration information, direction information, pressure information, temperature information, humidity information, and the like.

[0381] For example, the detection unit 250 may use a photodetector, a posture detector, an acceleration sensor, a direction sensor, a GPS (Global Positioning System) signal receiving circuit, a pressure-sensitive switch, a pressure sensor, a temperature sensor, a humidity sensor, a camera, or the like.

[0382] 《Communication Section 290》 The communication unit 290 has a function of supplying information to the network and acquiring information from the network.

[0383] 《Case》 The housing has a function of housing the input / output device 220 or the arithmetic device 210. Alternatively, the housing has a function of supporting the display unit 230 or the arithmetic device 210.

[0384] This makes it possible to generate control information based on input information or detection information. Or, it is possible to display image information based on input information or detection information. Or, it is possible for the information processing device to operate by grasping the intensity of light received by the housing of the information processing device in the environment in which the information processing device is used. Or, it is possible for the user of the information processing device to select the display method. As a result, it is possible to provide a novel information processing device that is excellent in convenience, usefulness, and reliability.

[0385] In addition, these components cannot be clearly separated, and one component may serve as another component or may include a part of another component. For example, a touch panel in which a touch sensor is superimposed on a functional panel is both a display unit and an input unit.

[0386] Configuration Example 2 of the Calculation Device 210 The computing device 210 includes an artificial intelligence unit 213 (see FIG. 14A).

[0387] The artificial intelligence unit 213 is supplied with the input information II or the sensed information DS, and infers the control information CI based on the input information II or the sensed information DS. The artificial intelligence unit 213 also supplies the control information CI.

[0388] This makes it possible to generate control information CI that is displayed in a way that is perceived as suitable. Or, it is possible to display control information CI that is displayed in a way that is perceived as suitable. Or, it is possible to generate control information CI that is displayed in a way that is perceived as comfortable. Or, it is possible to display control information CI that is displayed in a way that is perceived as comfortable. As a result, it is possible to provide a novel information processing device that is excellent in convenience, usefulness, and reliability.

[0389] [Natural language processing for input information II] Specifically, the artificial intelligence unit 213 can perform natural language processing on the input information II and extract one feature from the entire input information II. For example, the artificial intelligence unit 213 can infer emotions and the like contained in the input information II and make them a feature. It can also infer a color, pattern, font, and the like that is empirically felt to be suitable for the feature. The artificial intelligence unit 213 can also generate information that specifies the color, pattern, or font of characters, and information that specifies the color or pattern of the background, and use the information in the control information CI.

[0390] Specifically, the artificial intelligence unit 213 can extract some words contained in the input information II by natural language processing of the input information II. For example, the artificial intelligence unit 213 can extract grammatical errors, factual errors, or expressions containing emotions. In addition, the artificial intelligence unit 213 can generate control information CI that displays the extracted part in a color, pattern, font, or the like different from the other parts, and use the control information CI.

[0391] [Image processing for input information II] Specifically, the artificial intelligence unit 213 can perform image processing on the input information II and extract one feature from the input information II. For example, the artificial intelligence unit 213 can infer the year in which the input information II was photographed, whether indoors or outdoors, day or night, and the like, and use these as features. In addition, the artificial intelligence unit 213 can infer a color tone that is empirically felt to be suitable for the feature, and generate control information CI for using the color tone for display. Specifically, information specifying a color (for example, full color, black and white, or brown, etc.) used to express shading can be used in the control information CI.

[0392] Specifically, the artificial intelligence unit 213 can extract a part of an image included in the input information II by performing image processing on the input information II. For example, the artificial intelligence unit 213 can generate control information CI that displays a boundary between one part of the extracted image and another part. Specifically, the artificial intelligence unit 213 can generate control information CI that displays a rectangle that surrounds a part of the extracted image.

[0393] [Inference using detection information DS] Specifically, the artificial intelligence unit 213 can generate an inference using the detection information DS, or can generate control information CI based on the inference so that the user of the information processing device 200 feels comfortable.

[0394] Specifically, the artificial intelligence unit 213 can generate control information CI for adjusting the brightness of the display so that the brightness of the display is felt to be comfortable based on the illuminance of the environment, etc. Alternatively, the artificial intelligence unit 213 can generate control information CI for adjusting the volume so that the volume is felt to be comfortable based on the noise of the environment, etc.

[0395] Note that a clock signal or a timing signal supplied to the control unit 238 included in the display unit 230 can be used as the control information CI. Alternatively, a clock signal or a timing signal supplied to the control unit 248 included in the input unit 240 can be used as the control information CI.

[0396] <Configuration example 2 of information processing device> Another configuration of the information processing device of one embodiment of the present invention will be described with reference to FIGS. 15A and 15B.

[0397] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 15A).

[0398] [First step] In the first step, the settings are initialized (see FIG. 15A (S1)).

[0399] For example, predetermined image information to be displayed at the time of startup, a predetermined mode for displaying the image information, and information for specifying a predetermined display method for displaying the image information are obtained from the storage unit 212. Specifically, one still image information or other moving image information can be used as the predetermined image information. Also, the first mode or the second mode can be used as the predetermined mode.

[0400] [Second step] In the second step, interrupt processing is permitted (see FIG. 15A (S2)). Note that the arithmetic unit for which interrupt processing is permitted can perform the interrupt processing in parallel with the main processing. The arithmetic unit that has returned from the interrupt processing to the main processing can reflect the results obtained from the interrupt processing in the main processing.

[0401] When the counter value is the initial value, the arithmetic unit may perform an interrupt process, and when returning from the interrupt process, the counter may be set to a value other than the initial value. This allows interrupt processing to be always performed after the program is started.

[0402] [Third step] In a third step, the image information is displayed using a predetermined mode or a predetermined display method selected in the first step or interrupt process (see FIG. 15A (S3)). Note that the predetermined mode specifies the mode in which the information is displayed, and the predetermined display method specifies the method in which the image information is displayed. Also, for example, it can be used for information that displays image information VI.

[0403] For example, one way of displaying the image information VI may be associated with a first mode, and another way of displaying the image information VI may be associated with a second mode, allowing the display method to be selected based on the selected mode.

[0404] First mode Specifically, a method of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, and performing display based on the selection signal can be associated with the first mode.

[0405] For example, if the selection signal is supplied at a frequency of 30 Hz or more, and preferably 60 Hz or more, the movement of the moving image can be displayed smoothly.

[0406] For example, by updating the image at a frequency of 30 Hz or more, preferably 60 Hz or more, an image that changes so as to smoothly follow the user's operation can be displayed on the information processing device 200 being operated by the user.

[0407] Second Mode Specifically, a method of supplying a selection signal to one scan line at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute, and performing display based on the selection signal can be associated with the second mode.

[0408] Supplying the selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute can provide a display with reduced flicker or blinking, and can also reduce power consumption.

[0409] For example, when the information processing device 200 is used in a clock, the display can be updated once per second or once per minute.

[0410] Incidentally, for example, when a light-emitting element is used as a display element, the light-emitting element can be made to emit light in a pulsed manner to display image information. Specifically, the organic EL element can be made to emit light in a pulsed manner, and the afterglow can be used for display. Since the organic EL element has excellent frequency characteristics, it may be possible to shorten the time for driving the light-emitting element and reduce power consumption. Or, since heat generation is suppressed, it may be possible to reduce deterioration of the light-emitting element.

[0411] [Fourth step] In the fourth step, if an end command is supplied, the process proceeds to the fifth step, and if an end command is not supplied, the process proceeds to the third step (see FIG. 15A (S4)).

[0412] For example, the end command supplied in the interrupt process may be used for the judgment.

[0413] [5th ​​step] In the fifth step, the process ends (see FIG. 15A (S5)).

[0414] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 15B).

[0415] [Sixth step] In a sixth step, for example, the detection unit 250 detects the illuminance of the environment in which the information processing device 200 is used (see FIG. 15B (S6)). Note that instead of the illuminance of the environment, the color temperature or chromaticity of the ambient light may be detected.

[0416] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (see FIG. 15B (S7)). For example, the brightness of the display is determined so as not to be too dark or too bright.

[0417] It should be noted that if the color temperature or chromaticity of the ambient light is detected in the sixth step, the color of the display may be adjusted.

[0418] [8th step] In the eighth step, the interrupt process ends (see FIG. 15B (S8)).

[0419] <Configuration example 3 of information processing device> Another configuration of the data processing device of one embodiment of the present invention will be described with reference to FIG.

[0420] Fig. 16A is a flowchart illustrating a program according to one embodiment of the present invention, which is a flowchart illustrating an interrupt process different from the interrupt process shown in Fig. 15B.

[0421] Note that the configuration example 3 of the information processing device differs from the interrupt processing described with reference to Fig. 15B in that the interrupt processing includes a step of changing the mode based on a supplied predetermined event. Here, the different parts will be described in detail, and the above description will be used for parts where a similar configuration can be used.

[0422] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 16A).

[0423] [Sixth step] In the sixth step, if a predetermined event is supplied, the process proceeds to the seventh step, and if the predetermined event is not supplied, the process proceeds to the eighth step (see FIG. 16A (U6)). For example, whether or not a predetermined event is supplied within a predetermined period of time can be used as a condition. Specifically, the predetermined period can be a period of 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less, but longer than 0 seconds.

[0424] [Seventh step] In the seventh step, the mode is changed (see FIG. 16A (U7)). Specifically, if the first mode has been selected, the second mode is selected, and if the second mode has been selected, the first mode is selected.

[0425] For example, it is possible to change the display mode for a part of the region of the display unit 230. Specifically, it is possible to change the display mode for a region to which a selection signal is supplied by one of the drive circuits of the display unit 230 including the drive circuits GDA, GDB, and GDC (see FIG. 16B).

[0426] For example, when a predetermined event is supplied to the input unit 240 in an area overlapping with an area to which the drive circuit GDB supplies a selection signal, the display mode of the area to which the drive circuit GDB supplies a selection signal can be changed (see Figs. 16B and 16C). Specifically, the frequency of the selection signal supplied by the drive circuit GDB can be changed in response to a "tap" event supplied to the touch panel using a finger or the like.

[0427] The signal GCLK is a clock signal that controls the operation of the drive circuit GDB, and the signals PWC1 and PWC2 are pulse width control signals that control the operation of the drive circuit GDB. The drive circuit GDB supplies selection signals to the conductive films G2(m+1) to G2(2m) based on the signals GCLK, PWC1, and PWC2.

[0428] This allows, for example, the driver circuit GDB to supply a selection signal without the driver circuit GDA and the driver circuit GDC supplying a selection signal. Alternatively, the display of the area to which the driver circuit GDB supplies a selection signal can be updated without changing the display of the area to which the driver circuit GDA and the driver circuit GDC supply a selection signal. Alternatively, the power consumed by the driver circuit can be reduced.

[0429] [8th step] In the eighth step, the interrupt process is ended (see FIG. 16A (U8)). Note that the interrupt process may be repeatedly executed during the execution of the main process.

[0430] 《Specified Event》 For example, events such as "click" and "drag" provided using a pointing device such as a mouse, and events such as "tap," "drag," or "swipe" provided to a touch panel using a finger or the like as a pointer can be used.

[0431] Also, for example, the position of the slide bar pointed to by the pointer, the swipe speed, the drag speed, etc. can be used to provide arguments for commands associated with a given event.

[0432] For example, the information detected by the detection unit 250 can be compared with a preset threshold value, and the comparison result can be used for the event.

[0433] Specifically, a pressure-sensitive detector that comes into contact with a button or the like that is arranged so that it can be pressed into the housing can be used for the detection unit 250 .

[0434] Commands associated with specific events For example, the termination command may be associated with a certain event.

[0435] For example, a "page turn command" for switching the display from one image information to another can be associated with a specific event. In addition, an argument for determining the page turning speed used when executing the "page turn command" can be given using the specific event.

[0436] For example, a "scroll command" that moves the display position of a part of an image information and displays another part that is adjacent to the part can be associated with a specific event. Note that an argument that determines the speed at which the display is moved when the "scroll command" is executed can be given using the specific event.

[0437] For example, a command to set a display method or a command to generate image information can be associated with a specific event. An argument that determines the brightness of an image to be generated can be associated with a specific event. The argument that determines the brightness of an image to be generated can also be determined based on the brightness of the environment detected by the detection unit 250.

[0438] For example, a command to obtain information distributed using a push-type service using the communication unit 290 can be associated with a specific event.

[0439] The presence or absence of qualification to obtain information may be determined using location information detected by the detection unit 250. Specifically, it may be determined that the user is qualified to obtain information when the user is inside or in an area of ​​a specific classroom, school, conference room, company, building, etc. As a result, for example, educational materials distributed in a classroom of a school or university, etc., can be received and the information processing device 200 can be used as a textbook, etc. (see FIG. 14C). Or, materials distributed in a conference room of a company, etc. can be received and used as conference materials.

[0440] <Configuration example 4 of information processing device> Another configuration of the data processing device of one embodiment of the present invention will be described with reference to FIG.

[0441] Fig. 17A is a flowchart for explaining a program according to one embodiment of the present invention. Fig. 17A is a flowchart for explaining an interrupt process different from the interrupt process shown in Fig. 15B. Fig. 17B is a schematic diagram for explaining the operation of the program shown in Fig. 17A, and Fig. 17C is a schematic diagram of a photographed fingerprint.

[0442] Note that the configuration example 4 of the information processing device described with reference to Fig. 17A differs from the configuration example described with reference to Fig. 15B in the interrupt processing. Specifically, the interrupt processing includes a step of identifying an area based on a given event supplied, a step of generating an image, a step of displaying the image, and a step of capturing an image. Here, the different parts are described in detail, and the above description is used for parts that can use a similar configuration.

[0443] <<Interrupt Processing>> The interrupt process comprises a sixth step to an eleventh step (see FIG. 17A).

[0444] [Sixth step] In the sixth step, if the predetermined event is supplied, the process proceeds to a seventh step, and if the predetermined event is not supplied, the process proceeds to an eleventh step (see FIG. 17A (V6)).

[0445] For example, the detection unit 250 can be used to supply a predetermined event. Specifically, a motion such as lifting the information processing device can be used as the predetermined event. For example, an angular acceleration sensor or an acceleration sensor can be used to detect the motion of the information processing device. Or, a touch sensor can be used to detect contact or proximity of a subject such as a finger.

[0446] [Seventh step] In the seventh step, the first region SH is identified (see FIG. 17A (V7)).

[0447] For example, a region in contact with or close to a subject such as a finger on the input / output device 220 of one embodiment of the present invention can be the first region SH. Alternatively, a region set in advance by a user or the like can be used as the first region SH.

[0448] Specifically, a finger THM or the like in contact with or close to a functional panel that can be used in an information processing device of one embodiment of the present invention can be photographed using pixel 703(i,j) and the image can be processed to identify the first region SH (see Figure 17B).

[0449] For example, a shadow created by the contact or proximity of a subject such as a finger THM blocking external light can be captured using pixel 703(i,j) of a functional panel that can be used in an information processing device of one embodiment of the present invention, and the image can be processed to identify the first region SH.

[0450] Alternatively, pixel 703(i,j) of a functional panel that can be used in an information processing device of one embodiment of the present invention can be used to irradiate light onto an object such as a finger THM that is in contact with or in close proximity to the object, and the light reflected by the object can be captured using pixel 703(i,j) and processed to identify the first region SH.

[0451] Alternatively, a touch sensor can be used to identify an area touched by a subject such as a finger THM as the first area SH.

[0452] [8th step] In the eighth step, an image FI including a second region and a third region is generated based on the first region SH (see FIG. 17A (V8) and FIG. 17B). For example, the shape of the first region SH is used as the shape of the second region, and the region excluding the first region SH is used as the third region.

[0453] [9th step] In a ninth step, the image FI is displayed such that the second region overlaps the first region SH (see FIG. 17A (V9) and FIG. 17B).

[0454] For example, an image signal is generated from an image FI and supplied to the region 231, causing light to be emitted from the pixel 703(i,j). Alternatively, during the period in which the first selection signal is supplied to G1(i), the generated image signal can be supplied to the conductive film S1g(j) and the image signal can be written to the pixel 703(i,j). Alternatively, the generated image signal can be supplied to the conductive film S1g(j) and the conductive film S2g(j) and an enhanced image signal can be written to the pixel 703(i,j). Alternatively, the enhanced image signal can be used to display an image with increased luminance.

[0455] This allows the image FI to be displayed superimposed on the area 231 touched by the subject such as a finger or the like or the nearby area SH. Alternatively, light can be irradiated onto the area touched by the subject such as a finger using pixel 703(i,j). Alternatively, illumination can be applied to the subject such as a finger THM that is in contact or in close proximity. Alternatively, a user or the like can be prompted to touch or close a subject such as a finger to an area that has been set in advance.

[0456] [10th step] In a tenth step, an image of a subject in contact with or close to the first area SH is captured while the image FI is being displayed (see FIG. 17A (V10) and FIG. 17B).

[0457] For example, an image of a finger THM or the like close to the area 231 is captured while irradiating the finger with light. Specifically, a fingerprint FP of the finger THM in contact with the area 231 can be captured (see FIG. 17C).

[0458] For example, the supply of the first selection signal can be stopped while an image is displayed on pixel 703(i,j). For example, an image can be captured using pixel 703(i,j) while the supply of the selection signal to pixel circuit 530G(i,j) is stopped.

[0459] This allows an image of a subject such as a finger in contact or in close proximity to be captured while being illuminated. Or, an image can be captured during a period in which the first selection signal is not supplied. Or, noise during imaging can be suppressed. Or, a clear image of a fingerprint can be acquired. Or, an image that can be used for authenticating a user can be acquired. Or, a fingerprint of a finger touching the area 231 can be captured clearly no matter where in the area 231. As a result, a novel information processing device that is excellent in convenience, usefulness, and reliability can be provided.

[0460] [11th step] In the eleventh step, the interrupt process ends (see FIG. 17A (V11)).

[0461] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

Alternatively, multiple functional panels can be arranged to be used in one display area. Alternatively, multiple functional panels can be arranged to be used in a multi-screen. This allows the device to be used, for example, in an electronic whiteboard, electronic bulletin board, electronic signboard, etc.

[0475] "Configuration example 3 of information processing device" Information can be received from another device and displayed on the display unit 5230 (see FIG. 18D). Alternatively, several options can be displayed. Alternatively, the user can select some of the options and send a reply to the sender of the information.

Specifically, an individual identification signal can be received from a ring-shaped information processing device worn. Or, the individual identification signal can be supplied to a security system.

[0486] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0487] For example, when it is explicitly stated in this specification that X and Y are connected, the case where X and Y are electrically connected, the case where X and Y are functionally connected, and the case where X and Y are directly connected are considered to be disclosed in this specification, etc. Therefore, it is not limited to a specific connection relationship, for example, a connection relationship shown in a figure or text, and a connection relationship other than that shown in a figure or text is also considered to be disclosed in the figure or text.

[0488] Here, X and Y are objects (for example, a device, an element, a circuit, a wiring, an electrode, a terminal, a conductive film, a layer, etc.).

[0489] An example of a case where X and Y are directly connected is a case where an element that enables an electrical connection between X and Y (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.) is not connected between X and Y, and a case where X and Y are connected without an element that enables an electrical connection between X and Y (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.).

[0490] As an example of a case where X and Y are electrically connected, one or more elements (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.) that enable the electrical connection between X and Y can be connected between X and Y. The switch has a function of controlling on / off. In other words, the switch has a function of being in a conductive state (on state) or a non-conductive state (off state) and controlling whether or not a current flows. Alternatively, the switch has a function of selecting and switching a path for the current to flow. The case where X and Y are electrically connected includes the case where X and Y are directly connected.

[0491] As an example of a case where X and Y are functionally connected, one or more circuits that enable the functional connection between X and Y (for example, logic circuits (inverters, NAND circuits, NOR circuits, etc.), signal conversion circuits (DA conversion circuits, AD conversion circuits, gamma correction circuits, etc.), potential level conversion circuits (power supply circuits (boosting circuits, step-down circuits, etc.), level shifter circuits that change the potential level of a signal, etc.), voltage sources, current sources, switching circuits, amplifier circuits (circuits that can increase the signal amplitude or current amount, operational amplifiers, differential amplifier circuits, source follower circuits, buffer circuits, etc.), signal generation circuits, memory circuits, control circuits, etc.) can be connected between X and Y. As an example, even if another circuit is sandwiched between X and Y, if a signal output from X is transmitted to Y, X and Y are considered to be functionally connected. Note that the case where X and Y are functionally connected includes the case where X and Y are directly connected and the case where X and Y are electrically connected.

[0492] In addition, when it is explicitly stated that X and Y are electrically connected, the following cases are considered to be disclosed in this specification etc.: when X and Y are electrically connected (i.e., when they are connected with another element or circuit between them), when X and Y are functionally connected (i.e., when they are functionally connected with another circuit between them), and when X and Y are directly connected (i.e., when they are connected without another element or circuit between them). In other words, when it is explicitly stated that they are electrically connected, the same content as when it is simply and explicitly stated that they are connected is considered to be disclosed in this specification etc.

[0493] For example, when the source (or the first terminal, etc.) of the transistor is electrically connected to X via (or without) Z1 and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via (or without) Z2, or when the source (or the first terminal, etc.) of the transistor is directly connected to a part of Z1, another part of Z1 is directly connected to X, the drain (or the second terminal, etc.) of the transistor is directly connected to a part of Z2, and another part of Z2 is directly connected to Y, it can be expressed as follows.

[0494] For example, it can be expressed as "X, Y, and the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor are electrically connected to each other, and are electrically connected in the order of X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y." Or, it can be expressed as "The source (or first terminal, etc.) of the transistor is electrically connected to X, the drain (or second terminal, etc.) of the transistor is electrically connected to Y, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are electrically connected in this order." Or, it can be expressed as "X is electrically connected to Y through the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are provided in this connection order." By using expressions similar to these examples to specify the order of connections in a circuit configuration, the source (or first terminal, etc.) and drain (or second terminal, etc.) of a transistor can be distinguished and the technical scope can be determined.

[0495] Alternatively, as another way of expressing it, for example, it can be expressed as "the source (or the first terminal, etc.) of the transistor is electrically connected to X via at least a first connection path, the first connection path does not have a second connection path, the second connection path is a path between the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor via a transistor, the first connection path is a path via Z1, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via at least a third connection path, the third connection path does not have the second connection path, and the third connection path is a path via Z2." Alternatively, it can be expressed as "the source (or the first terminal, etc.) of the transistor is electrically connected to X via Z1 by at least a first connection path, the first connection path does not have a second connection path, the second connection path has a connection path via a transistor, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third connection path, and the third connection path does not have the second connection path." Alternatively, it can be expressed as follows: "The source (or first terminal, etc.) of the transistor is electrically connected to X via Z1 by at least a first electrical path, the first electrical path does not have a second electrical path, the second electrical path is an electrical path from the source (or first terminal, etc.) of the transistor to the drain (or second terminal, etc.) of the transistor, and the drain (or second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third electrical path, the third electrical path does not have a fourth electrical path, and the fourth electrical path is an electrical path from the drain (or second terminal, etc.) of the transistor to the source (or first terminal, etc.) of the transistor." By using an expression method similar to these examples to define the connection path in the circuit configuration, the source (or first terminal, etc.) and the drain (or second terminal, etc.) of the transistor can be distinguished to determine the technical scope.

[0496] Note that these representation methods are merely examples and are not limited to these representation methods. Here, X, Y, Z1, and Z2 are objects (for example, a device, an element, a circuit, a wiring, an electrode, a terminal, a conductive film, a layer, etc.).

[0497] In addition, even when components that are independent on a circuit diagram are shown as being electrically connected to each other, one component may have the functions of multiple components. For example, when a part of a wiring also functions as an electrode, one conductive film has both the functions of a wiring and an electrode. Therefore, the term "electrical connection" in this specification also includes such a case where one conductive film has the functions of multiple components. [Explanation of symbols]
