Region 231 comprises region 231(1), region 231(2), region 231(3), region 231(4), and a fifth region 231(5). Region 231(2) has a function to display in one direction (for example, the direction indicated by arrow Z in the figure).

[0071] Region 231(3) is sandwiched between regions 231(1) and 231(2), and region 231(3) can be bent (see Figures 1B and 1C).

[0079] 《Example 1 of the configuration of the photoelectric conversion element PD(2)》 The photoelectric conversion element PD(2) has the function of converting light h1 into an electrical signal. Furthermore, as the surface 210(3) is bent, the photoelectric conversion element PD(2) faces the light-emitting element 550(1) (see Figures 1C, 2A, and 2B).

Light-emitting materials, a hole transport layer, and an electron transport layer can all be used in the light-emitting element 550.

[0084] 《Example 2 of the configuration of the photoelectric conversion element PD(2)》

[0085] The photoelectric conversion element PD(2) includes a photoelectric conversion material. For example, fullerene can be used in the photoelectric conversion element PD(2). Alternatively, for example, an electron-accepting material and an electron-donating material can be used as the photoelectric conversion material. Alternatively, a laminated film of an electron-accepting material and an electron-donating material can be used as the photoelectric conversion material. Alternatively, a mixed film of an electron-accepting material and an electron-donating material can be used as the photoelectric conversion material.

The photoelectric conversion layer is sandwiched between the hole transport layer and the electron transport layer, and the photoelectric conversion layer includes a photoelectric conversion material. For example, a hole transport layer that can be used in the light-emitting element 550(1) can be used in the photoelectric conversion element PD(2). Alternatively, an electron transport layer that can be used in the light-emitting element 550(1) can be used in the photoelectric conversion element PD(2). Alternatively, a hole transport layer that can be fabricated in the same process can be used in both the light-emitting element 550(1) and the photoelectric conversion element PD(2). Alternatively, an electron transport layer that can be fabricated in the same process can be used in both the light-emitting element 550(1) and the photoelectric conversion element PD(2).

[0092] (Embodiment 2) In this embodiment, the configuration of a functional panel that can be used in an information processing device according to one aspect of the present invention will be described with reference to Figures 3 to 6.

[0095] Figure 5 illustrates the configuration of a functional panel that can be used in an information processing device according to one embodiment of the present invention. Figure 5 is a circuit diagram of the pixel circuit 530G(i,j) of the functional panel.

[0096] Figure 6 illustrates the operation of a function panel that can be used in an information processing device according to one embodiment of the present invention.

[0097] <Example of function panel configuration 1> The functional panel described in this embodiment includes a drive circuit GD, a drive circuit RD, and a region 231 (see Figure 3A). Region 231 includes region 231(2) (see Figure 1A).

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

[0099] 《Example of pixel 703(i,j) configuration 1》 Pixel 703(i,j) comprises 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 Figures 3B and 3C).

[0100] 《Example Configuration 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) acquires 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 Figure 3B). Alternatively, 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 called "writing" (see Figure 6).

[0102] 《Example Configuration 1 of Light-Emitting Device 550G(i,j)》 The light-emitting element 550G(i,j) is electrically connected to the pixel circuit 530G(i,j), and the light-emitting element 550G(i,j) emits light based on the image signal (see Figures 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 Figures 5 and 10A).

[0104] 《Example Configuration 1 of Pixel Circuit 530S(i,j)》 The pixel circuit 530S(i,j) is supplied with a second and a third selection signal during periods when it is not supplied with a first selection signal (see Figure 6). Furthermore, 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 Figures 3B and 4A).

[0105] The operation of supplying a second selection signal and causing the pixel circuit 530S(i,j) to acquire the imaging signal can be called "imaging" (see Figure 6). The operation of reading the imaging signal from the pixel circuit 530S(i,j) can be called "readout". Furthermore, 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 can be called "exposure", and the operation of reflecting the voltage changed due to 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 correlated double sampling, and "output" corresponds to the operation of supplying the imaging signal.

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

[0107] For example, image information from one frame can be stored for a period equivalent to 16 frames. Alternatively, imaging information from one frame can be captured and retrieved for a period equivalent to 16 frames.

[0108] Specifically, initialization can be performed in 15 μs, exposure in 1 ms to 5 ms, and data transfer in 150 μs. Alternatively, data can be read out in 250 ms.

[0109] 《Example 1 of the configuration of the 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 the imaging signal. For example, the photoelectric conversion element PD(2) described in Embodiment 1 can be used as the photoelectric conversion element PD(i,j).

[0110] This allows imaging to be performed during periods when the first selection signal is not supplied, or to suppress noise during imaging. Alternatively, it allows reading the imaging signal during periods when the first selection signal is not supplied, or to suppress noise during reading. As a result, a novel functional panel with superior convenience, usefulness, or 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 Figures 4A and 9A). Furthermore, the electrode 552 used in the light-emitting element 550G(i,j) can be used in the photoelectric conversion element PD(i,j). This simplifies the configuration and manufacturing process of the functional panel.

[0112] 《Example of pixel 703(i,j) configuration 2》 Multiple pixels can be used for pixel 703(i,j). For example, multiple pixels displaying colors with different hues can be used. Note that each of these multiple pixels can be referred to as a subpixel. Alternatively, multiple subpixels can be grouped together and referred to as a single pixel.

[0113] This allows for additive or subtractive color mixing of the colors displayed by the multiple pixels. Alternatively, it enables the display of hues that cannot be displayed by individual pixels.

[0114] Specifically, the pixels 702B(i,j) which display blue, 702G(i,j) which display green, and 702R(i,j) which display red can be used as pixel 703(i,j). In addition, pixels 702B(i,j), 702G(i,j), and 702R(i,j) can each be referred to as subpixels (see Figure 7B).

[0115] Furthermore, for example, a pixel that displays white, etc., can be used in addition to the above set of pixels 703(i,j). Also, a pixel that displays cyan, a pixel that displays magenta, and a pixel that displays yellow can be used in pixels 703(i,j).

[0116] Furthermore, for example, a pixel emitting infrared light can be added to the above set and used as pixel 703(g,h) (see Figure 7C). Specifically, a pixel 702N(g,h) that emits light including light with wavelengths between 650nm and 1000nm can be used as pixel 703(g,h).

[0117] 《Example of pixel 703(i,j) configuration 3》 Pixel 703(i,j) is supplied with a second selection signal during the period in which it holds one image signal. For example, during the period in which pixel circuit 530G(i,j) holds one image signal, pixel 703(i,j) can emit light based on that image signal using the light-emitting element 550G(i,j) (see Figure 6). Alternatively, after pixel circuit 530G(i,j) acquires one image signal based on the first selection signal, and before it is supplied with the first selection signal again, pixel circuit 530S(i,j) is supplied with a second selection signal.

[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 illuminated 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 illuminating light. Alternatively, 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 can be eliminated. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0119] 《Example of pixel 703(i,j) configuration 4》 Pixel 703(i,j) is supplied with a third selection signal during the period in which it holds one image signal. For example, while pixel circuit 530G(i,j) acquires one image signal based on the first selection signal and is supplied with the first selection signal again, pixel circuit 530S(i,j) is supplied with a second selection signal (see Figure 6).

[0120] This eliminates the influence on the imaging signal caused by changes in the signal held by the pixel circuit 530G(i,j) from one image signal to another. As a result, it is possible to provide a novel functional panel with superior convenience, usefulness, and reliability.

[0121] <Example of function panel configuration 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 Figure 4A). Furthermore, the conductive film TX(i) is supplied with a second selection signal, and the conductive film SE(i) is supplied with a third selection signal.

[0122] 《Example Configuration of Pixel Circuit 530S(i,j) 2》 The pixel circuit 530S(i,j) includes switches SW31, SW32, SW33, transistor M31, capacitor C31, and 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 to control the conduction state or non-conduction state based on the potential of the conductive film TX(i).

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

[0125] Capacitor C31 comprises a conductive film electrically connected to node FD and a conductive film electrically connected to conductive film VCP.

[0126] Transistor M31 comprises a gate electrode electrically connected to node FD and a first electrode electrically connected to the conductive film VPI.

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

[0129] <Example of function panel configuration 3> A functional panel that can be used in an information processing device according to 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 Figure 5). The conductive film G1(i) is supplied with a first selection signal. 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 the signal supplied using the conductive film S1g(j). For example, an image signal can be supplied in 15.2 μs using the conductive film S1g(j). Alternatively, it can be supplied in 30.4 μs using both the conductive film S1g(j) and the conductive film S2g(j).

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

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

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

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

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

[0135] This allows the image signal to be stored in node N21. Alternatively, the potential of node N21 can be changed using switch SW22. Or, the intensity of the light emitted by the light-emitting element 550G(i,j) can be controlled using the potential of node N21. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0136] <Example of function panel configuration 4> A functional panel that can be used in an information processing device according to one embodiment of the present invention has a conductive film V0 (see Figure 5).

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

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

[0139] Capacitor C22 comprises a conductive film electrically connected to node N21 and a conductive film electrically connected to node N22.

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

[0141] <Example of function panel configuration 5> A functional panel that can be used in an information processing device according to one embodiment of the present invention includes a readout circuit RC(j), a conductive film VLEN, a conductive film VIV, and a conductive film CL (see Figures 3A, 4A, 4B, and 4C).

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

[0143] Example of an amplification circuit configuration The amplification circuit includes transistor M32(j) (see Figure 4B).

[0144] The transistor M32(j) comprises 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 switch SW33 is in the conductive state, the conductive film WX(j) connects transistors M31(j) and M32(j) (see Figures 4A and 4B). This allows a source follower circuit to be constructed using transistors M31(j) and M32(j). Alternatively, the potential of the conductive film WX(j) can be changed based on the potential of node FD.

[0146] 《Example configuration of sampling circuit SC(j)》 The sampling circuit SC(j) includes a first terminal IN(j), a second terminal, and a third terminal OUT(j) (see Figure 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 allows the imaging signal to be acquired from the pixel circuit 530S(i,j). Alternatively, a correlated double sampling method can be applied, for example. Alternatively, a sampling circuit SC(j) can be provided for each conductive film WX(j). The difference signal of the pixel circuit 530S(i,j) can be acquired for each conductive film WX(j). Alternatively, the operating frequency of the sampling circuit SC(j) can be suppressed. Alternatively, noise can be reduced. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0149] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0150] (Embodiment 3) In this embodiment, the configuration of a functional panel that can be used in an information processing device according to one aspect of the present invention will be described with reference to Figures 7 to 11.

[0156] <Example of function panel configuration 6> A functional panel that can be used in an information processing device according to one embodiment of the present invention has a functional layer 520 (see Figure 8).

[0157] 《Example Configuration of Functional Layer 520 1》 The functional layer 520 includes pixel circuits 530G(i,j) and 530S(i,j). The functional layer 520 also includes apertures 591G and 591S.

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

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

[0160] This allows the pixel circuits 530G(i,j) and 530S(i,j) to be formed on the functional layer 520. Alternatively, for example, the semiconductor film used for the pixel circuit 530S(i,j) can be formed in the process of forming the semiconductor film used for the pixel circuit 530G(i,j). Alternatively, the manufacturing process of the functional panel can be simplified. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

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

[0162] This allows, for example, the formation of semiconductor films used in the pixel circuit 530G(i,j) during the process of forming the semiconductor film used in the drive circuit GD, drive circuit RD, and readout circuit RC. Alternatively, the fabrication process of the functional panel can be simplified. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

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

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

[0165] Examples of transistor configurations The transistor comprises a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see Figure 10B). Alternatively, the transistor comprises a conductive film 512C and a conductive film 512D (see Figure 11B). Alternatively, the transistor comprises a conductive film 512E and a conductive film 512F (see Figure 9B).

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

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

[0168] The insulating film 506 comprises 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 the function of a source electrode or a drain electrode, and the conductive film 512B has either the function of a source electrode or a drain electrode.

[0170] Furthermore, the conductive film 524 can be used in a transistor. The conductive film 524 includes a region in which a semiconductor film 508 is sandwiched between it and the conductive film 504. The conductive film 524 functions as a second gate electrode.

[0171] Furthermore, in the process of forming the semiconductor film used for the transistors in the pixel circuit, the semiconductor film used for the transistors in the drive circuit can also be formed.

[0172] 《Example 1 of semiconductor film 508 configuration》 For example, a semiconductor containing group 14 elements 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 makes it easier to enlarge the functional panel.

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

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

[0176] Alternatively, the temperature required for transistor fabrication can be lowered compared to, for example, transistors using single-crystal silicon.

[0177] Alternatively, the semiconductor film used for the transistors in the drive circuit can be formed using the same process as the semiconductor film used for the transistors in the pixel circuit. Alternatively, the drive circuit can be formed on the same substrate as the substrate on which the pixel circuit is formed. Alternatively, the number of components constituting the 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 resolution than, for example, a functional panel using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, it is possible to provide a functional panel with less display unevenness than a functional panel using polysilicon for the semiconductor film 508. Alternatively, for example, smart glasses or a head-mounted display can be provided.

[0179] 《Example 2 of the configuration of semiconductor film 508》 For example, a metal oxide can be used for the semiconductor film 508. This allows the pixel circuit to hold the image signal for a longer time compared to a pixel circuit using a transistor with amorphous silicon as 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, fatigue accumulated by the user of the information processing device can be reduced. Power consumption associated with driving can also be reduced. Furthermore, the pixel circuit can hold the imaging signal for a longer time compared to a pixel circuit using a transistor with amorphous silicon as 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 take images using a global shutter method. Furthermore, it is possible to photograph moving subjects with reduced distortion.

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

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

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

[0183] For example, a conductive film can be used as the conductive film 504, which is a laminate of a 10 nm thick film containing tantalum and nitrogen and a 300 nm thick film containing copper. The copper-containing film includes a region where the tantalum and nitrogen-containing film is sandwiched between it and the insulating film 506.

[0184] For example, a laminated film consisting of a 400 nm thick film containing silicon and nitrogen and a 200 nm thick film containing silicon, oxygen, and nitrogen can be used as the insulating film 506. The film containing silicon and nitrogen includes a region between it and the semiconductor film 508 where the film containing silicon, oxygen, and nitrogen is sandwiched.

[0185] For example, a conductive film can be used as conductive film 512A or conductive film 512B if it is made by stacking a 50 nm thick film containing tungsten, a 400 nm thick film containing aluminum, and a 100 nm thick film containing titanium in this order. The tungsten-containing film has a region that is in contact with the semiconductor film 508.

[0186] Incidentally, for example, a manufacturing line for bottom-gate transistors using amorphous silicon as the semiconductor material can be easily converted to a manufacturing line for bottom-gate transistors using oxide semiconductors. Similarly, a manufacturing line for top-gate transistors using polysilicon as the semiconductor material can be easily converted to a manufacturing line for top-gate transistors using oxide semiconductors. In either case, existing manufacturing lines can be effectively utilized.

[0187] This can suppress flickering, reduce power consumption, display fast-moving videos smoothly, or display photos and other images with rich gradations. As a result, it is possible to provide a novel functional panel with superior convenience, usefulness, and reliability.

[0188] 《Example 3 of the configuration of semiconductor film 508》 For example, compound semiconductors can be used as semiconductors in transistors. Specifically, semiconductors containing gallium arsenide can be used.

[0189] For example, organic semiconductors can be used as semiconductors in transistors. Specifically, organic semiconductors containing polyacenes or graphene can be used as semiconductor films.

[0190] Examples of capacity configurations The capacitance comprises one conductive film, another conductive film, and an insulating film. The insulating film includes a region sandwiched between the one conductive film and the other conductive film.

[0191] For example, conductive film 504, conductive film 512A, and insulating film 506 can be used as capacitance.

[0192] 《Example Configuration of Functional Layer 520 2》 Furthermore, the functional layer 520 includes insulating film 521, insulating film 518, insulating film 516, insulating film 506, insulating film 501C, etc. (see Figure 10A).

[0193] The insulating film 521 includes a region sandwiched between the pixel circuit 530G(i,j) and the light-emitting element 550G(i,j).

[0194] The insulating film 518 includes a region sandwiched between the insulating film 521 and the insulating film 501C.

[0196] The insulating film 506 includes a region sandwiched between the insulating film 516 and the insulating film 501C.

[0197] [Insulating film 521] For example, insulating inorganic materials, insulating organic materials, or insulating composite materials containing inorganic and organic materials can be used as the insulating film 521.

[0198] Specifically, an inorganic oxide film, an inorganic nitride film, or an inorganic oxidnitride film, or a laminated material obtained by laminating a combination of these, can be used as the insulating film 521.

[0199] For example, films containing silicon oxide films, silicon nitride films, silicon oxynitride films, aluminum oxide films, or laminated materials comprising a combination of these can be used as the insulating film 521. Note that silicon nitride films are dense films and have excellent properties for suppressing the diffusion of impurities.

[0200] For example, the insulating film 521 can be made from polyester, polyolefin, polyamide, polyimide, polycarbonate, polysiloxane, or acrylic resin, or a laminated or composite material of multiple resins selected from these. It may also be formed using a photosensitive material. This allows the insulating film 521 to flatten steps caused by various structures overlapping the insulating film 521.

[0201] Furthermore, polyimide possesses superior properties compared to other organic materials in terms of thermal stability, insulation, toughness, low dielectric constant, low coefficient of thermal expansion, and chemical resistance. Therefore, polyimide can be particularly suitable for use in insulating films such as 521.

[0202] Furthermore, for example, a film formed using a photosensitive material can be used as the insulating film 521. Specifically, a film formed using a photosensitive polyimide or a photosensitive acrylic resin can be used as the insulating film 521.

[0203] [Insulation film 518] For example, a material that can be used for insulating film 521 can be used for insulating film 518.

[0204] For example, materials that have the function of suppressing the diffusion of oxygen, hydrogen, water, alkali metals, alkaline earth metals, etc., can be used for the insulating film 518. Specifically, nitride insulating films can be used for the insulating film 518. For example, silicon nitride, silicon oxide nitride, aluminum nitride, aluminum oxide nitride, etc., can be used for the insulating film 518. This makes it possible to suppress the diffusion of impurities into the semiconductor film of the transistor.

[0205] [Insulating film 516] For example, a material that can be used for insulating film 521 can be used for insulating film 516.

[0206] Specifically, a film manufactured using a different method than that used for the insulating film 518 can be used for the insulating film 516.

[0207] [Insulating film 506] For example, a material that can be used for insulating film 521 can be used for insulating film 506.

[0208] Specifically, films including silicon oxide film, silicon oxide nitride film, silicon nitride film, silicon nitride film, aluminum oxide film, hafnium oxide film, yttrium oxide film, zirconium oxide film, gallium oxide film, tantalum oxide film, magnesium oxide film, lanthanum oxide film, cerium oxide film, or neodymium oxide film can be used as the insulating film 506.

[0209] [Insulating film 501D] The insulating film 501D includes a region sandwiched between the insulating film 501C and the insulating film 516.

[0210] For example, a material that can be used for insulating film 506 can be used for insulating film 501D.

[0211] [Insulating film 501C] For example, a material that can be used for insulating film 521 can be used for insulating film 501C. Specifically, a material containing silicon and oxygen can be used for insulating film 501C. This makes it possible to suppress the diffusion of impurities into pixel circuits, light-emitting elements, or photoelectric conversion elements.

[0212] 《Example 3 of Functional Layer 520 Configuration》 The functional layer 520 comprises a conductive film, wiring, and terminals. Conductive materials can be used for the wiring, electrodes, terminals, conductive film, etc.

[0213] 《Wiring, etc.》 For example, inorganic conductive materials, organic conductive materials, metals, or conductive ceramics can be used for wiring, etc.

[0214] Specifically, metal elements selected from aluminum, gold, platinum, silver, copper, chromium, tantalum, titanium, molybdenum, tungsten, nickel, iron, cobalt, palladium, or manganese can be used for wiring, etc. Alternatively, alloys containing the above-mentioned metal elements can be used for wiring, etc. In particular, alloys of copper and manganese are suitable for microfabrication using the wet etching method.

[0215] Specifically, two-layer structures such as a titanium film laminated on an aluminum film, a titanium film laminated on a titanium nitride film, a tungsten film laminated on a titanium nitride film, a tungsten film laminated on a tantalum nitride or tungsten nitride film, and a three-layer structure consisting of a titanium film, an aluminum film laminated on the titanium film, and a titanium film formed on top of that can be used for wiring and the like.

[0216] Specifically, conductive oxides such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, and zinc oxide with added gallium can be used in wiring and other applications.

[0217] Specifically, films containing graphene or graphite can be used for wiring and the like.

[0218] For example, a graphene-containing film can be formed by creating a film containing graphene oxide and then reducing the graphene oxide-containing film. Methods of reduction include applying heat or using a reducing agent.

[0219] For example, a film containing metal nanowires can be used for wiring and the like. Specifically, nanowires containing silver can be used.

[0220] Specifically, conductive polymers can be used in wiring and other applications.

[0221] For example, terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using conductive material ACF1 (see Figure 8). Specifically, terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using conductive material CP.

[0222] <Example configuration of the 700 function panel 2> Furthermore, the functional panel 700 comprises a base material 510, a base material 770, and a sealing material 705 (see Figure 10A).

[0223] 《Base material 510, base material 770》 A translucent material can be used for the base material 510 or the base material 770.

[0224] For example, a flexible material can be used for the base material 510 or base material 770. This makes it possible to provide a functional panel with flexibility.

[0225] For example, materials with a thickness of 0.1 mm to 0.7 mm can be used. Specifically, materials polished to a thickness of approximately 0.1 mm can be used. This allows for a reduction in weight.

[0226] Incidentally, glass substrates of the 6th generation (1500mm x 1850mm), 7th generation (1870mm x 2200mm), 8th generation (2200mm x 2400mm), 9th generation (2400mm x 2800mm), and 10th generation (2950mm x 3400mm) can be used as base material 510 or base material 770. This makes it possible to manufacture large-scale display devices.

[0227] Organic materials, inorganic materials, or composite materials such as organic and inorganic materials can be used as the base material 510 or base material 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, or sapphire can be used for the base material 510 or base material 770. Alternatively, aluminosilicate glass, tempered glass, chemically strengthened glass, or sapphire can be suitably used for the base material 510 or base material 770 located on the side of the functional panel closest to the user. This prevents damage and scratches to the functional panel during use.

[0229] Specifically, inorganic oxide films, inorganic nitride films, or inorganic oxynitride films can be used. For example, silicon oxide films, silicon nitride films, silicon oxynitride films, aluminum oxide films, etc., can be used. Stainless steel or aluminum, etc., can be used as the base material 510 or base material 770.

[0230] For example, single-crystal semiconductor substrates made of silicon or silicon carbide, polycrystalline semiconductor substrates, compound semiconductor substrates such as silicon germanium, SOI substrates, etc., can be used as the base material 510 or base material 770. This allows semiconductor devices to be formed on the base material 510 or base material 770.

[0231] For example, organic materials such as resins, resin films, or plastics can be used as the base material 510 or base material 770. Specifically, materials containing polyester, polyolefin, polyamide (nylon, aramid, etc.), polyimide, polycarbonate, polyurethane, or acrylic resin, epoxy resin, or silicone resins having siloxane bonds can be used as the base material 510 or base material 770. For example, resin films, resin plates, or laminated materials containing these materials can be used. This can reduce weight. Alternatively, it can reduce the frequency of damage caused by drops, for example.

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

[0233] For example, a composite material obtained by laminating a film of a metal plate, a thin glass plate, or an inorganic material with a resin film can be used as the base material 510 or base material 770. For example, a composite material obtained by dispersing fibrous or particulate metal, glass, or inorganic material in a resin can be used as the base material 510 or base material 770. For example, a composite material obtained by dispersing fibrous or particulate resin or organic material in an inorganic material can be used as the base material 510 or base material 770.

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

[0235] Furthermore, paper or wood can be used as the base material 510 or base material 770.

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

[0237] For example, a method can be used in which an insulating film, transistor, or capacitor is formed on a process substrate that is heat-resistant to the heat applied during the manufacturing process, and the formed insulating film, transistor, or capacitor is then transferred to, for example, a base material 510 or a base material 770. This makes it possible to form an insulating film, transistor, or capacitor on, for example, a flexible substrate.

[0238] 《Sealing material 705》 The sealing material 705 has a region sandwiched between the functional layer 520 and the substrate 770, and has the function of bonding the functional layer 520 and the substrate 770 together (see Figure 10A).

[0239] Inorganic materials, organic materials, or composite materials of inorganic and organic materials can be used as the sealing material 705.

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

[0241] For example, organic materials such as reaction-curing adhesives, photocuring adhesives, thermosetting adhesives, and / or anaerobic adhesives can be used in the encapsulant 705.

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

[0243] <Example configuration of the 700 function panel 3> The functional panel 700 includes a functional layer 720 (see Figure 10A). The functional panel 700 also includes structural elements such as KB.

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

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

[0246] 《Insulating film 771》 The insulating film 771 includes a region sandwiched between the substrate 770 and the light-shielding film BM.

[0247] 《Structure KB》 Structure KB comprises a region sandwiched between the functional layer 520 and the base material 770. Furthermore, structure KB has the function of providing a predetermined gap between the functional layer 520 and the base material 770.

[0248] <Example configuration of the 700 function panel 4> The functional panel 700 includes a functional film 770P, etc. (see Figure 10A).

[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, anti-reflective films, polarizing films, phase difference films, light-diffusing films, or light-gathering films can be used as the functional film 770P.

[0251] For example, an anti-reflective film with a thickness of 1 μm or less can be used for the functional film 770P. Specifically, a laminated film in which three or more, preferably five or more, and more preferably fifteen or more, dielectric layers are stacked 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 as the functional film 770P.

[0253] Furthermore, functional films such as antistatic films to suppress dust adhesion, water-repellent films to make it difficult for dirt to adhere, oil-repellent films to make it difficult for dirt to adhere, anti-reflective films, anti-glare films, hard coat films to suppress the occurrence of scratches during use, and self-healing films that repair scratches that do occur can be used on the 770P functional film.

[0254] <Example configuration of the 700 function panel 5> Furthermore, the functional panel 700 has insulating film 528 and insulating film 573 (see Figure 10A).

[0255] 《Insulating Film 528》 The insulating film 528 includes 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, materials that can be used for the insulating film 521 can be used for the insulating film 528. Specifically, a silicon oxide film, a film containing an acrylic resin, a film containing a polyimide, or the like can be used for the insulating film 528.

[0257] 《Insulating Film 573》 The insulating film 573 includes a region sandwiching the light-emitting element 550G(i,j) between it and the functional layer 520 (see FIG. 10A).

[0258] For example, a laminated film formed by laminating a single film or a plurality of films can be used for the insulating film 573. Specifically, a laminated film formed by laminating an insulating film 573A that can be formed in a manner that is difficult to damage the light-emitting element 550G(i,j) and a dense insulating film 573B with few defects can be used for the insulating film 573. Thereby, diffusion of impurities into the light-emitting element 550G(i,j) can be suppressed. Or, the reliability of the light-emitting element 550G(i,j) can be enhanced.

[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, an electrode 551G(i,j), an electrode 552, and a layer 553G(j) containing a light-emitting material can be used for the light-emitting element 550G(i,j). Further, the layer 553G(j) containing a light-emitting material includes a region sandwiched between the electrode 551G(i,j) and the electrode 552.

[0261] 《Example 1 of the composition of layer 553G(j) containing luminescent material》 For example, the laminated material can be used in layer 553G(j) which contains a luminescent material.

[0262] For example, materials that emit blue light, green light, red light, infrared light, or ultraviolet light can be used in layer 553G(j) which contains the luminescent material.

[0263] 《Example 2 of the composition of layer 553G(j) containing luminescent material》 For example, a laminated material that is laminated to emit white light can be used in layer 553G(j) which contains a light-emitting material.

[0264] Specifically, multiple materials that emit light of different hues can be used in layer 553G(j) which contains the luminescent material.

[0265] For example, a laminated material comprising a layer containing a luminescent material including a fluorescent material that emits blue light and a layer containing materials other than fluorescent materials that emit green and red light can be used as the luminescent material-containing layer 553G(j). Alternatively, a laminated material comprising a layer containing a luminescent material including a fluorescent material that emits blue light and a layer containing materials other than fluorescent materials that emit yellow light can be used as the luminescent material-containing layer 553G(j).

[0266] Furthermore, a colored film CF can be superimposed on the luminescent material-containing layer 553G(j). This makes it possible to extract light of a predetermined hue from white light.

[0267] 《Example 3 of the composition of layer 553G(j) containing luminescent material》 For example, a laminated material that emits blue light or ultraviolet light can be used in layer 553G(j) containing a light-emitting material. Alternatively, for example, a color conversion layer CC can be used in addition.

[0268] 《Example 4 of the composition of layer 553G(j) containing luminescent material》 The layer 553G(j) containing the luminescent material comprises a light-emitting unit. The light-emitting unit has one region in which electrons injected from one side recombine with holes injected from the other side. The light-emitting unit also contains the luminescent material, which emits the energy generated by the recombination of electrons and holes as light. Note that hole transport layers and electron transport layers can be used in the light-emitting unit. The hole transport layer is located on the positive electrode side of the electron transport layer, and the hole transport layer has a higher hole mobility than the electron transport layer.

[0269] For example, multiple light-emitting units and an intermediate layer can be used in 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 generation region and has the function of supplying holes to the light-emitting unit located on the cathode side and supplying electrons to the light-emitting unit located on the anode side. A configuration having multiple light-emitting units and an intermediate layer is sometimes called a tandem type light-emitting device.

[0270] This allows for increased current efficiency in light emission, or, at the same brightness, a reduction in the current density flowing through the light-emitting element, or an improvement in the reliability of the light-emitting element.

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

[0272] Incidentally, for example, polymer compounds (oligomers, dendrimers, polymers, etc.) and medium-molecular-weight compounds (compounds in the intermediate region between low-molecular-weight and high-molecular-weight compounds: molecular weight between 400 and 4000) can be used in layer 553G(j) containing the luminescent material.

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

[0274] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide added with gallium, etc. can be used. Or, a metal film thin enough for light to pass through can be used. Or, materials having translucency for 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 electrode 551G(i,j) or electrode 552. For example, a layer 553G(j) containing a light-emitting material or the like is used to adjust the distance between electrode 551G(i,j) and electrode 552.

[0276] Thereby, a micro resonator structure can be provided in the light-emitting element 550G(i,j). Or, light of a predetermined wavelength can be extracted more efficiently than other light. Or, light having a narrow half-value width of the spectrum can be extracted. Or, light of a vivid color can be extracted.

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

[0278] Also, electrode 551G(i,j) is electrically connected to the pixel circuit 530G(i,j) at the opening 591G (see FIG. 9A). Electrode 551G(i,j) overlaps, for example, an opening formed in the insulating film 528, and electrode 551G(i,j) is provided with the insulating film 528 at the periphery.

[0279] This prevents short circuits between electrodes 551G(i,j) and 552.

[0280] 《Example 1 of the configuration of the photoelectric conversion element PD(i,j)》 The photoelectric conversion element PD(i,j) comprises an electrode 551S(i,j), an electrode 552, and a layer 553S(j) containing a photoelectric conversion material (see Figure 9A).

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

[0282] [Example 1 of the composition of layer 553S(j) containing photoelectric conversion material] For example, a multilayer film in which a p-type semiconductor film and an n-type semiconductor film are stacked in contact with each other can be used in layer 553S(j) containing the photoelectric conversion material. A photoelectric conversion element PD(i,j) that uses a multilayer film with such a structure in layer 553S(j) containing the 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 stacked, with an i-type semiconductor film sandwiched between a p-type semiconductor film and an n-type semiconductor film, can be used in layer 553S(j) containing the photoelectric conversion material. A photoelectric conversion element PD(i,j) that uses such a laminated film structure in layer 553S(j) containing the 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 stacked, with a p-type semiconductor film sandwiched between a p-type semiconductor film and an n-type semiconductor film, and a p-type semiconductor film sandwiched between the p-type semiconductor film and the n-type semiconductor film, can be used in layer 553S(j) containing the photoelectric conversion material. A photoelectric conversion element PD(i,j) that uses a laminated film with such a structure in layer 553S(j) containing the photoelectric conversion material can be called an avalanche photodiode.

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

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

[0287] Specifically, the hole transport layer and electron transport layer used in layer 553G(j) containing the luminescent material can be used in layer 553S(j) containing the photoelectric conversion material. This simplifies the manufacturing process.

[0288] Also, for example, fullerene (for example, C 60 , C 70 Electron-accepting organic semiconductor materials such as (etc.) or their derivatives can be used in n-type semiconductor films.

[0289] Furthermore, electron-donating organic semiconductor materials such as copper(II) phthalocyanine (CuPc) or tetraphenyldibenzoperiflanthene (DBP) can be used in p-type semiconductor films.

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

[0291] 《Example of configuration for area 231》 Region 231 comprises a group of pixels 703(i,1) to 703(i,n) and another group of pixels 703(1,j) to 703(m,j) (see Figure 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 a group of pixels 703(i,1) to 703(i,n) includes pixel 703(i,j).

[0293] Furthermore, 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 the column direction intersecting the row direction (indicated by arrow C1 in the figure), and each of the other group of pixels 703(1,j) to 703(m,j) includes pixel 703(i,j).

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

[0296] This allows for the acquisition of imaging information from multiple pixels, or the supply of image information to multiple pixels. As a result, it is possible to provide a novel functional panel with superior convenience, usefulness, and reliability.

[0297] 《Example of configuration for area 231 2》 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 a light-emitting element 550(1) (see Figures 2C and 2D). Specifically, a pixel 702B(g,h) that displays blue, a pixel 702G(g,h) that displays green, a pixel 702R(g,h) that displays red, and a pixel 702N(g,h) that includes a light-emitting element 550(1) can be used for pixel 703(g,h) (see Figures 2C and 7C).

[0299] <Example of function panel configuration 7> Furthermore, a functional panel that can be used in an information processing device according to one embodiment of the present invention includes a multiplexer MUX, an amplification circuit AMP, and an analog-to-digital conversion circuit ADC (see Figure 3A).

[0300] The multiplexer MUX has the function of selecting one of several sampling circuits SC(j) to acquire the imaging signal and supplying it to, for example, an amplification circuit AMP.

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

[0302] This allows for the selection of a predetermined pixel from multiple pixels arranged in a row to acquire imaging information. Alternatively, the number of imaging signals acquired simultaneously can be limited to a predetermined number. Or, an analog-to-digital converter (ADC) can be used with fewer input channels than the number of pixels arranged in a row. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0303] The amplification circuit (AMP) can amplify the imaging signal and supply it to the analog-to-digital conversion circuit (ADC).

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

[0305] This allows, for example, the formation of semiconductor films used in the pixel circuit 530G(i,j) during the semiconductor film formation process, as well as the formation of semiconductor films used in the multiplexer MUX and the amplifier circuit AMP. Alternatively, it simplifies the fabrication process of the functional panel. As a result, it is possible to provide a novel functional panel with superior convenience, usefulness, or reliability.

[0306] An analog-to-digital converter (ADC) has the function of converting analog imaging signals into digital signals.

[0307] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0308] (Embodiment 4) In this embodiment, the configuration of a functional panel that can be used in an information processing device according to one aspect of the present invention will be described with reference to Figure 12.

[0309] Figure 12 is a diagram illustrating the configuration of a display device according to one embodiment of the present invention. Figure 12A is a block diagram of the display device according to one embodiment of the present invention, and Figures 12B to 12D are projection views illustrating the 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 includes a function panel 700 and a control unit 238 (see Figure 12A).

[0311] 《Example of configuration of the control unit 238 1》 The control unit 238 is supplied with image information VI and control information CI. For example, a clock signal or timing signal can be used as the control information CI.

[0312] The control unit 238 generates information V11 based on image information VI and generates control signals based on control information CI. The control unit 238 also supplies information V11 and control signals.

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

[0314] 《Example of configuration of control unit 238 2》 For example, the stretching circuit 234 and the image processing circuit 235 can be used in the control unit 238.

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

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

[0317] The image processing circuit 235 includes, for example, a function to correct image information VI based on a predetermined characteristic curve to generate information V11, and a function to supply information V11.

[0318] 《Example of a function panel configuration 1》 The function panel 700 is supplied with information V11 and control signals. For example, the function panel 700 described in Embodiment 2 or Embodiment 3 can be used.

[0319] 《Example of pixel 703(i,j) configuration 5》 Pixel 703(i,j) emits light based on information V11. Similarly, pixel 703(g,h) also emits light based on information V11.

[0320] This allows image information to be displayed using a 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 superior convenience, usefulness, or reliability can be provided. Alternatively, for example, a smartwatch (see Figure 12B), a video monitor (see Figure 12C), or a notebook computer (see Figure 12D) can be provided.

[0321] 《Example of a function panel configuration 2》 For example, the function panel 700 includes a drive circuit and a control circuit (see Figure 12A).

[0322] 《Drive Circuit》 The drive circuit operates based on a control signal. By using a control signal, the operation of multiple drive circuits can be synchronized.

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

[0324] Furthermore, for example, the drive circuit SD can be used in the function panel 700. The drive circuit SD is supplied with control signals and information V11, and can supply image signals.

[0325] Furthermore, for example, the drive circuit RD can be used in the function panel 700. The drive circuit RD is supplied with control signals and can supply a second selection signal.

[0326] Furthermore, for example, the readout circuit RC can be used in the function panel 700. The readout circuit RC is supplied with a control signal and can read out the imaging signal using, for example, correlated double sampling.

[0327] Control circuit 243 The control circuit 243 has the function of generating and supplying control signals. 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 in the functional panel. Alternatively, 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] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0331] (Embodiment 5) In this embodiment, the configuration of an input / output device according to one aspect of the present invention will be described with reference to Figure 13.

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

[0333] <Example of Input / Output Device Configuration 1> The input / output device described in this embodiment has an input unit 240 and a display unit 230 (see Figure 13).

[0334] [Example of the configuration of the display unit 230] The display unit 230 includes a function panel. For example, the function panel 700 described in Embodiment 2 or Embodiment 3 can be used for the display unit 230. The configuration having an input unit 240 and a display unit 230 can be referred to as an input / output panel 700TP.

[0335] [Example configuration of input unit 240] The input unit 240 includes a detection area 241. The input unit 240 has a function to detect objects that are close to the detection area 241.

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

[0337] This allows for the detection of objects approaching an area overlapping with the display unit while simultaneously displaying image information using the display unit. Alternatively, position information can be input using a finger or other object placed near the display unit as a pointer. Furthermore, position information can be associated with the image information displayed on the display unit. As a result, a novel input / output device with superior convenience, usefulness, and reliability can be provided.

[0338] 《Example of configuration of detection area 241 1》 The detection area 241 includes, for example, one or more detectors.

[0339] The detection region 241 includes a group of detectors 802(g,1) to 802(g,q) and another group of detectors 802(1,h) to 802(p,h). 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 detector 802(g,h) and is arranged in the row direction (the direction indicated by arrow R2 in the figure). The direction indicated by arrow R2 may be the same as or different from the direction indicated by arrow R1.

[0341] Furthermore, another group of detectors 802(1,h) to detectors 802(p,h) include detector 802(g,h) and are arranged in the column direction intersecting the row direction (indicated by arrow C2 in the figure).

[0342] Detector The detector has the 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, capacitive proximity sensors, electromagnetic induction proximity sensors, optical proximity sensors, and resistive proximity sensors can be used as detectors.

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

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

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

[0347] 《Example of the configuration of the input unit 240 2》 The input section 240 includes an oscillator circuit OSC and a detection circuit DC (see Figure 13).

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

[0349] The detector 802(g,h) generates and supplies a detection signal that changes based on the distance to the pointer adjacent to the detector 802(g,h) and the search signal.

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

[0351] This allows for the detection of the distance from a nearby pointer to the detection area 241. Alternatively, it allows for the detection of the closest position of the pointer within the detection area 241.

[0352] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0353] (Embodiment 6) In this embodiment, the configuration of an information processing device according to one aspect of the present invention will be described with reference to Figures 14 to 16.

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

[0357] <Example of Information Processing Device Configuration 1> The information processing device described in this embodiment includes an arithmetic unit 210 and an input / output device 220 (see Figure 14A). The input / output device 220 is electrically connected to the arithmetic unit 210. The information processing device 200 may also be provided with a housing (see Figures 14B and 14C).

[0358] 《Example of Configuration of the Calculation Unit 210》 The arithmetic unit 210 is supplied with input information II or detection information DS. Based on the input information II or detection information DS, the arithmetic unit 210 generates control information CI and image information VI, and supplies the control information CI and image information VI.

[0359] The arithmetic unit 210 comprises an arithmetic unit 211 and a storage unit 212. The arithmetic unit 210 also comprises a transmission line 214 and an input / output interface 215.

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

[0361] 《Calculation section 211》 The arithmetic unit 211 includes, for example, a function for executing a program.

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

[0363] Specifically, hard disks, flash memory, or memory using transistors containing oxide semiconductors can be used.

[0364] Input / output interface 215, transmission path 214 The input / output interface 215 is equipped with terminals or wiring and has the function of supplying and receiving information. For example, it can be electrically connected to the transmission line 214. It can also be electrically connected to the input / output device 220.

[0365] The transmission line 214 is equipped with wiring and has the function of supplying and receiving information. For example, it can be electrically connected to the input / output interface 215. It can also be electrically connected to the arithmetic unit 211, the storage unit 212, or the input / output interface 215.

[0366] 《Example configuration of input / output device 220》 Input / output device 220 supplies input information II and detection information DS. Input / output device 220 is also supplied with control information CI and image information VI (see Figure 14A).

[0367] For example, keyboard scan codes, location information, button operation information, audio information, or image information can be used as input information II. Alternatively, for example, illumination information, posture information, acceleration information, orientation information, pressure information, temperature information, or humidity information of the environment in which the information processing device 200 is used can be used as detection information DS.

[0368] For example, signals that control the brightness, saturation, and hue of the image information VI can be used in the control information CI. Alternatively, signals that change the display of a part of the image information VI can be used in 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 Embodiment 5 can be used as the input / output device 220. The input / output device 220 may also include a communication unit 290.

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

[0371] The display unit 230 includes a control unit 238, a drive circuit GD, a drive circuit SD, and a function panel 700 (see Figure 12). For example, the display device described in Embodiment 4 can be used in the display unit 230.

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

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

[0374] Furthermore, a touch sensor having an area that overlaps with the display unit 230 can be used. An input / output device comprising the display unit 230 and a touch sensor having an area that overlaps with the display unit 230 can be referred to as a touch panel or touch screen.

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

[0376] For example, the arithmetic unit 210 analyzes information such as the position or trajectory of a finger in contact with the touch panel, and when the analysis result satisfies predetermined conditions, it can be determined that a predetermined gesture has been supplied. This allows the user to supply a predetermined operation command, which is pre-associated with the predetermined gesture, using that gesture.

[0377] For example, a user can issue a "scroll command" to change the display position of image information using a gesture of moving their finger along the touch panel.

[0378] Furthermore, the user can issue a "drag command" to pull out and display the navigation panel NP at the edge of area 231 using a gesture of moving a finger touching the edge of area 231 (see Figure 14C). The user can also issue a "leaf-through command" to display the index image IND, parts of other pages, or thumbnail images TN of other pages in a predetermined order on the navigation panel NP using a gesture of moving the position of the finger pressing down firmly, or by using the pressure of the finger pressing down. This allows the user to turn the pages of the e-book reader as if flipping through the pages of a paper book, or to find a specific page by relying on the thumbnail image TN or index image IND.

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

[0380] The detection unit 250 has the function of detecting the surrounding conditions and supplying detection information. Specifically, it can supply illuminance information, attitude information, acceleration information, orientation information, pressure information, temperature information, or humidity information, etc.

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

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

[0383] Cabinet The enclosure also has the function of housing the input / output device 220 or the arithmetic unit 210. Alternatively, the enclosure has the function of supporting the display unit 230 or the arithmetic unit 210.

[0384] This allows control information to be generated based on input or detection information. Alternatively, image information can be displayed based on input or detection information. Alternatively, the information processing device can operate by sensing the intensity of light received by the device's casing in the environment in which it is used. Alternatively, the user of the information processing device can select a display method. As a result, a novel information processing device with superior convenience, usefulness, or reliability can be provided.

[0385] These components cannot be clearly separated, and one component may serve as a substitute for another, or may include parts of another component. For example, a touch panel with a touch sensor superimposed on a functional panel is both a display unit and an input unit.

[0386] 《Example Configuration of the Calculation Unit 210 2》 The computing unit 210 includes an artificial intelligence unit 213 (see Figure 14A).

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

[0388] This makes it possible to generate control information CIs that are displayed in a way that feels preferable, or to display them in a way that feels preferable, or to generate control information CIs that are displayed in a way that feels comfortable, or to display them in a way that feels comfortable. As a result, it is possible to provide a novel information processing device that is superior in convenience, usefulness, or reliability.

[0389] [Natural language processing on input information II] Specifically, the artificial intelligence unit 213 can perform natural language processing on the input information II and extract a single feature from the entire input information II. For example, the artificial intelligence unit 213 can infer emotions or other emotions embedded in the input information II and make them a feature. It can also infer colors, patterns, or fonts that are empirically perceived as suitable for that feature. Furthermore, the artificial intelligence unit 213 can generate information specifying the color, pattern, or font of the characters, or the color or pattern of the background, and use this information in the control information CI.

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

[0391] [Image processing for input information II] Specifically, the artificial intelligence unit 213 can process the input information II as an image and extract a feature from it. For example, the artificial intelligence unit 213 can infer the year the input information II was taken, whether it was indoors or outdoors, and whether it was day or night, and use these as features. It can also infer a color tone that is empirically considered suitable for that feature and generate control information CI for using that color tone in the display. Specifically, information specifying the color to be used to represent shades (e.g., full color, black and white, or brown) can be used in the control information CI.

[0392] Specifically, the artificial intelligence unit 213 can process the input information II to extract a portion of the image contained in the input information II. For example, it can generate control information CI that displays a boundary between a portion of the extracted image and another portion. More specifically, it can generate control information CI that displays a rectangle surrounding a portion of the extracted image.

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

[0394] Specifically, based on ambient illuminance, the artificial intelligence unit 213 can generate control information CI to adjust the brightness of the display so that the brightness is perceived as comfortable. Alternatively, the artificial intelligence unit 213 can generate control information CI to adjust the volume so that the volume is perceived as comfortable, based on ambient noise, etc.

[0395] Furthermore, the clock signal or timing signal supplied to the control unit 238 of the display unit 230 can be used as control information CI. Alternatively, the clock signal or timing signal supplied to the control unit 248 of the input unit 240 can be used as control information CI.

[0396] <Example of Information Processing Device Configuration 2> Another configuration of an information processing device according to one aspect of the present invention will be described with reference to Figures 15A and 15B.

[0397] "program" A program according to one aspect of the present invention has the following steps (see Figure 15A).

[0398] [Step 1] In the first step, the settings are initialized (see Figure 15A(S1)).

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

[0400] [Step 2] In the second step, interrupt handling is enabled (see Figure 15A(S2)). An arithmetic unit (AGS) that has been enabled for interrupt handling can perform interrupt processing in parallel with the main processing. After returning to the main processing from interrupt handling, the AGS can reflect the results obtained from the interrupt processing back into the main processing.

[0401] Furthermore, when the counter value is at its initial value, the arithmetic unit may be prompted to perform an interrupt, and upon returning from the interrupt, the counter may be set to a value other than the initial value. This allows the program to always perform an interrupt after it starts.

[0402] [Step 3] In the third step, the image information is displayed using a predetermined mode or display method selected in the first step or interrupt processing (see Figure 15A(S3)). 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. For example, this can be used for the information to be displayed, such as the image information VI.

[0403] For example, one method of displaying the image information VI can be associated with a first mode, or another method of displaying the image information VI can be associated with a second mode. This allows the display method to be selected based on the selected mode.

[0404] Mode 1 Specifically, a method of supplying a selection signal to a scan line at a frequency of 30 Hz or higher, preferably 60 Hz or higher, and displaying based on the selection signal, can be associated with the first mode.

[0405] For example, supplying a selection signal at a frequency of 30Hz or higher, preferably 60Hz or higher, allows for smooth display of motion in the video.

[0406] For example, by updating the image at a frequency of 30Hz or higher, preferably 60Hz or higher, an image that changes smoothly to follow the user's actions can be displayed on the information processing device 200 that the user is operating.

[0407] Mode 2 Specifically, a method of supplying a selection signal to a scan line at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute, and displaying based on the selection signal, can be associated with the second mode.

[0408] By supplying a selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute, a display with suppressed flicker or blinking can be achieved. Furthermore, power consumption can be reduced.

[0409] For example, if the information processing device 200 is used as a clock, the display can be updated at a frequency of once per second or once per minute, etc.

[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, an organic EL element can be made to emit light in a pulsed manner, and its afterglow can be used for display. Because organic EL elements have excellent frequency characteristics, it may be possible to shorten the time required to drive the light-emitting element and reduce power consumption. Alternatively, since heat generation is suppressed, it may be possible to reduce the degradation of the light-emitting element.

[0411] [Step 4] In the fourth step, if a termination command is supplied, the system chooses to proceed to the fifth step; otherwise, it chooses to proceed to the third step (see Figure 15A(S4)).

[0412] For example, the termination command supplied during interrupt handling may be used for the decision.

[0413] [Step 5] In the fifth step, the process is completed (see Figure 15A(S5)).

[0414] Interrupt handling Interrupt handling comprises the following steps 6 through 8 (see Figure 15B).

[0415] [Step 6] In the sixth step, for example, the detection unit 250 is used to detect the illuminance of the environment in which the information processing device 200 is used (see Figure 15B(S6)). Alternatively, the color temperature or chromaticity of the ambient light may be detected instead of the illuminance of the environment.

[0416] [Step 7] In the seventh step, the display method is determined based on the detected illuminance information (see Figure 15B(S7)). For example, the brightness of the display is determined so that it is neither too dim nor too bright.

[0417] Furthermore, if the color temperature or chromaticity of the ambient light is detected in step 6, the displayed color may be adjusted.

[0418] [Step 8] In the eighth step, the interrupt processing is terminated (see Figure 15B(S8)).

[0419] <Example 3 of Information Processing Device Configuration> Another configuration of an information processing device according to one aspect of the present invention will be described with reference to Figure 16.

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

[0421] Note that configuration example 3 of the information processing device differs from the interrupt processing described with reference to Figure 15B in that it includes a step in the interrupt processing that changes the mode based on a predetermined event that is supplied. Here, the differences will be explained in detail, and the above explanation will be used as a reference for parts where a similar configuration can be used.

[0422] Interrupt handling Interrupt processing comprises the following steps 6 through 8 (see Figure 16A).

[0423] [Step 6] In the sixth step, if a predetermined event is supplied, proceed to the seventh step; otherwise, proceed to the eighth step (see Figure 16A(U6)). For example, the condition can be whether or not a predetermined event was supplied within a predetermined period. Specifically, the predetermined period can be 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less, and longer than 0 seconds.

[0424] [Step 7] In the seventh step, change the mode (see Figure 16A(U7)). Specifically, if you had selected the first mode, select the second mode, and if you had selected the second mode, select the first mode.

[0425] For example, the display mode can be changed for a portion of the display unit 230. Specifically, the display mode can be changed for a portion of the display unit 230 that is supplied with a selection signal by one of the drive circuits GDA, GDB, and GDC (see Figure 16B).

[0426] For example, if a predetermined event is supplied to the input unit 240, which is located in an area that overlaps with the area to which the drive circuit GDB supplies the selection signal, the display mode of the area to which the drive circuit GDB supplies the selection signal can be changed (see Figures 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 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 conductive films G2(m+1) to G2(2m) based on signals GCLK, PWC1, and PWC2, etc.

[0428] This allows, for example, the drive circuit GDB to supply a selection signal without the drive circuits GDA and GDC supplying a selection signal. Alternatively, the display of the area supplied with a selection signal by the drive circuit GDB can be updated without the display of the area supplied with a selection signal by the drive circuits GDA and GDC being changed. Or, the power consumption of the drive circuits can be reduced.

[0429] [Step 8] In the eighth step, the interrupt handling is terminated (see Figure 16A(U8)). Note that the interrupt handling may be repeatedly executed during the period in which the main processing is running.

[0430] 《Scheduled Events》 For example, events such as "click" and "drag" can be supplied using a pointing device such as a mouse, or events such as "tap," "drag," or "swipe" can be supplied to a touch panel using a finger or other object as a pointer.

[0431] Furthermore, arguments for commands associated with a given event can be provided using, for example, the position of the slider bar pointed to by the pointer, the swipe speed, the drag speed, etc.

[0432] For example, the information detected by the detection unit 250 can be compared with a pre-set threshold, and the comparison result can be used as an event.

[0433] Specifically, the detection unit 250 can use a pressure sensor or the like that contacts a button or the like that is positioned to be pressed into the housing.

[0434] 《Instructions to associate with a specified event》 For example, a termination command can be associated with a predetermined event.

[0435] For example, a "page-turning command" that switches the display from one image to another can be associated with a predetermined event. Furthermore, arguments determining the page-turning speed used when executing the "page-turning command" can be provided using this predetermined event.

[0436] For example, a "scroll command" that moves the display position of a portion of an image to display other portions continuous with that portion can be associated with a predetermined event. Furthermore, arguments determining the speed at which the display moves when executing the "scroll command" can be provided using a predetermined event.

[0437] For example, commands to set the display method or commands to generate image information can be associated with predetermined events. Furthermore, an argument for determining the brightness of the generated image can also be associated with a predetermined event. Alternatively, the argument for determining the brightness of the generated image may be determined based on the brightness of the environment detected by the detection unit 250.

[0438] For example, commands to acquire information delivered using a push-type service, using the communication unit 290, can be associated with a predetermined event.

[0439] Furthermore, the presence or absence of eligibility to acquire information may be determined using location information detected by the detection unit 250. Specifically, it may be determined that the user is eligible to acquire information if they are inside or within a designated classroom, school, conference room, company, building, etc. This allows, for example, the information processing device 200 to receive educational materials distributed in a classroom at a school or university and use them as textbooks, etc. (see Figure 14C). Alternatively, it can receive materials distributed in a conference room at a company, etc., and use them as meeting materials.

[0440] <Example of Information Processing Device Configuration 4> Another configuration of an information processing device according to one aspect of the present invention will be described with reference to Figure 17.

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

[0442] Note that Configuration Example 4 of the information processing device, which will be explained with reference to Figure 17A, differs from the Configuration Example explained with reference to Figure 15B in its interrupt processing. Specifically, the interrupt processing includes the steps of identifying a region, generating an image, displaying the image, and capturing an image based on a predetermined event that is supplied. Here, the differences will be explained in detail, and the above explanation will be used as a reference for parts where a similar configuration can be used.

[0443] Interrupt handling The interrupt handling process comprises steps 6 through 11 (see Figure 17A).

[0444] [Step 6] In step 6, if the predetermined event is supplied, proceed to step 7; otherwise, proceed to step 11 (see Figure 17A(V6)).

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

[0446] [Step 7] In the seventh step, the first region SH is identified (see Figure 17A(V7)).

[0447] For example, in one embodiment of the present invention, the input / output device 220 can be configured to use a first region SH in which an object such as a finger has come into contact with or is in close proximity to it. Alternatively, a region pre-set by the user can be used as the first region SH.

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

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

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

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

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

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

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

[0455] This allows the image FI to be displayed over the area 231 touched by a subject such as a finger, or an adjacent area SH. Alternatively, light can be shone onto the area touched by a subject such as a finger using pixel 703(i,j). Alternatively, illumination can be shone onto a subject such as a finger THM that is in contact or in close proximity. Alternatively, the user can be prompted to touch or bring a subject such as a finger into a pre-set area.

[0456] [Step 10] In the tenth step, while displaying the image FI, an image is captured of a subject that is in contact with or close to the first region SH (see Figures 17A(V10) and 17B).

[0457] For example, a finger THM adjacent to region 231 is illuminated with light while the finger is photographed. Specifically, the fingerprint FP of the finger THM in contact with region 231 can be photographed (see Figure 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, imaging can be performed using pixel 703(i,j) while the supply of the selection signal to pixel circuit 530G(i,j) is stopped.

[0459] This allows for imaging of subjects such as fingers that are in contact or nearby, while illuminating them. Alternatively, it allows for imaging during periods when the first selection signal is not supplied. Alternatively, it allows for suppression of noise during imaging. Alternatively, it allows for the acquisition of clear images of fingerprints. Alternatively, it allows for the acquisition of images that can be used for user authentication. Alternatively, it allows for the clear capture of fingerprints of fingers touching area 231, regardless of their location within area 231. As a result, a novel information processing device with superior convenience, usefulness, or reliability can be provided.

[0460] [Step 11] In the 11th step, the interrupt processing is terminated (see Figure 17A(V11)).

[0461] This embodiment can be appropriately combined with other embodiments shown in this specification.

Specifically, it can receive individual identification signals from a ring-shaped information processing device worn on the body. Alternatively, it can supply individual identification signals to a security system.

[0486] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0487] For example, where it is explicitly stated in this specification that X and Y are connected, this specification discloses the cases in which X and Y are electrically connected, functionally connected, and directly connected. Therefore, predetermined connection relationships, not limited to those shown in the figures or text, are also disclosed in the figures or text.

[0488] Here, X and Y are assumed to be objects (for example, devices, elements, circuits, wiring, electrodes, terminals, conductive films, layers, etc.).

[0489] An example of a case where X and Y are directly connected is when there are no elements that enable electrical connection between X and Y (e.g., switches, transistors, capacitive elements, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.) connected between X and Y, and when X and Y are connected without any elements that enable electrical connection between X and Y (e.g., switches, transistors, capacitive elements, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.).

[0490] One example of a case where X and Y are electrically connected is that one or more elements that enable electrical connection between X and Y (e.g., switches, transistors, capacitive elements, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.) can be connected between X and Y. A switch has the function of controlling on / off states. That is, a switch has the function of controlling whether or not current flows by being in a conductive state (on state) or a non-conductive state (off state). Alternatively, a switch has the function of selecting and switching the path through which current flows. Note that when X and Y are electrically connected, this includes cases where X and Y are directly connected.

[0491] One example of a functional connection between X and Y is when 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 (boost circuits, buck circuits, etc.), level shifter circuits that change the potential level of a signal, etc.), voltage sources, current sources, switching circuits, amplification circuits (circuits that can increase the signal amplitude or current amount, such as operational amplifiers, differential amplifiers, 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 placed between X and Y, if the signal output from X is transmitted to Y, X and Y are considered to be functionally connected. Furthermore, a functional connection between X and Y includes cases where X and Y are directly connected and cases where X and Y are electrically connected.

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

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

[0494] For example, it can be expressed as, "X, Y, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor are electrically connected to each other, and the connection is 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." Alternatively, it can be expressed as, "The source (or first terminal, etc.) of the transistor is electrically connected to X, and 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." Alternatively, it can be expressed as, "X is electrically connected to Y via 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 similar notation to these examples to define 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 their technical scopes determined.

[0495] Alternatively, it can be expressed as follows: "The source (or 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 first terminal, etc.) of the transistor and the drain (or second terminal, etc.) of the transistor via the transistor, the first connection path is a path via Z1, the drain (or 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 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 through the transistor, and the drain (or second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third connection path, the third connection path does not have the second connection path." Alternatively, it can be expressed as: "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, 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, 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 defining the connection paths in the circuit configuration using expressions similar to these examples, the source (or first terminal, etc.) and the drain (or second terminal, etc.) of the transistor can be distinguished and the technical scope determined.

[0496] These methods of expression are merely examples and are not limited to them. Here, X, Y, Z1, and Z2 are assumed to be objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, layers, etc.).

[0497] Even if independent components are shown as electrically connected in a circuit diagram, a single component may possess the functions of multiple components. For example, if part of a wire also functions as an electrode, a single conductive film possesses the functions of both a wire and an electrode. Therefore, in this specification, "electrically connected" includes cases where a single conductive film possesses the functions of multiple components. [Explanation of Symbols]
