[0009] The optical element has a first cross-section on a first plane, and in the first cross-section, the first surface traces a first curve. The first curve also has a first radius of curvature R1.

[0010] The second surface faces the first surface, and the second surface is illuminated by the first light.

[0011] The insulating film is sandwiched between the optical element and the first region, and the insulating film is in contact with the second surface.

[0013] The distance L1 has the relationship shown in equation (i) between it and the first radius of curvature R1 and the first refractive index N1.

[0014] (Math 1) L1 ≤ 5 × R1 / (N1 - 1) (i)

[0015] This allows the light emitted from the first region to be focused in the direction in front of the first region where the first region and the optical element ML overlap. Alternatively, the light emitted from the first region can be utilized efficiently. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0019] The second surface faces the first surface, and the second surface is illuminated by the first light.

[0020] The insulating film is sandwiched between the optical element and the first region, and the insulating film is in contact with the second surface.

[0021] The sealing material is in contact with the first surface, and the sealing material has a second refractive index N2, the second refractive index N2 being smaller than the first refractive index N1.

[0022] The first region overlaps with the second surface, the first region faces the second surface, and the first region emits the first light. Also, the first region has a distance L1 from the second surface.

[0023] The distance L1 has a relationship shown in Equation (ii) with the first radius of curvature R1, the first refractive index N1, and the second refractive index N2.

[0024] (Equation 2) L1 ≤ 5 × R1 × N2 / (N1 - N2) (ii)

[0037] Furthermore, the second curve comprises a second region, the second region being flat or having a second radius of curvature R2, where the second radius of curvature R2 is greater than the first radius of curvature R1.

[0060] In the drawings attached to this specification, components are classified by function and shown as independent blocks in block diagrams. However, in reality, it is difficult to completely separate components by function, and a single component may be involved in multiple functions.

[0061] In this specification, the terms "source" and "drain" of a transistor are interchangeable depending on the transistor's polarity and the potential applied to each terminal. Generally, in an n-channel transistor, the terminal to which a low potential is applied is called the source, and the terminal to which a high potential is applied is called the drain. Similarly, in a p-channel transistor, the terminal to which a low potential is applied is called the drain, and the terminal to which a high potential is applied is called the source. For convenience, this specification sometimes describes the connection relationships of a transistor assuming that the source and drain are fixed, but in reality, the terms "source" and "drain" are interchangeable according to the potential relationship described above.

[0062] In this specification, the source of a transistor refers to the source region, which is part of the semiconductor film that functions as the active layer, or the source electrode connected to the semiconductor film. Similarly, the drain of a transistor refers to the drain region, which is part of the semiconductor film, or the drain electrode connected to the semiconductor film. The gate refers to the gate electrode.

[0063] In this specification, a state in which transistors are connected in series means, for example, a state in which only one source or drain of the first transistor is connected to only one source or drain of the second transistor. A state in which transistors are connected in parallel means a state in which one source or drain of the first transistor is connected to one source or drain of the second transistor, and the other source or drain of the first transistor is connected to the other source or drain of the second transistor.

[0064] In this specification, "connection" means an electrical connection, corresponding to a state in which current, voltage, or potential can be supplied or transmitted. Therefore, a connected state does not necessarily refer to a direct connection, but also includes a state indirectly connected through circuit elements such as wiring, resistors, diodes, and transistors, so that current, voltage, or potential can be supplied or transmitted.

[0065] In this specification, even when components that appear independent in a circuit diagram are connected, in reality, a single conductive film may combine the functions of multiple components, for example, when a portion of the wiring functions as an electrode. In this specification, "connection" includes such cases where a single conductive film combines the functions of multiple components.

[0066] In this specification, one of the first or second electrodes of the transistor refers to the source electrode, and the other refers to the drain electrode. [Effects of the Invention]

Alternatively, a novel information processing device with superior convenience, usefulness, or reliability can be provided. Alternatively, a novel functional panel, a novel display device, a novel input / output device, a novel information processing device, or a novel semiconductor device can be provided.

[0068] Furthermore, the description of these effects does not preclude the existence of other effects. Moreover, one aspect of the present invention does not necessarily have to possess all of these effects. Other effects will naturally become apparent from the description in the specification, drawings, and claims, and it is possible to extract other effects from the description in the specification, drawings, and claims.

[0070] A functional panel according to one aspect of the present invention comprises an optical element, a first insulating film, and a region. The optical element has a first refractive index N1, is a convex lens, has a first surface and a second surface, has a first cross-section on the first plane, the first surface draws a first curve in the first cross-section, the first curve has a first radius of curvature R1, the second surface faces the first surface, the second surface is irradiated with first light, the first insulating film is sandwiched between the optical element and the region, the first insulating film is in contact with the second surface, the region overlaps with the second surface, the region faces the second surface, the region emits first light, and the region has a distance L1 between itself and the second surface. The distance L1 has the following relationship between the first radius of curvature R1 and the first refractive index N1: L1 ≤ 5 × R1 / (N1 - 1).

[0071] This allows the light emitted by the region to be focused in the direction in front of the region where the region and the optical element overlap. Alternatively, the light emitted by the region can be utilized efficiently. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0072] Embodiments will be described in detail with reference to the drawings. However, it will be readily apparent to those skilled in the art that the present invention is not limited to the following description, and that its form and details can be modified in various ways without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be interpreted as being limited to the contents of the embodiments shown below. In the configuration of the invention described below, the same reference numerals are used in common across different drawings for the same parts or parts having similar functions, and repeated descriptions are omitted.

[0073] (Embodiment 1) In this embodiment, the configuration of a functional panel according to one aspect of the present invention will be described with reference to Figures 1A to 6B.

[0079] Figure 6A is a top view illustrating a part of a functional panel according to one embodiment of the present invention, Figure 6B is a cross-sectional view along the cutting line XA-XB in Figure 6A, and Figure 6C is a cross-sectional view along the cutting line YA-YB in Figure 6A.

[0080] Figure 7A is a top view of a functional panel according to one embodiment of the present invention, Figure 7B is a diagram illustrating a part of Figure 7A, and Figure 7C is a diagram illustrating a part of Figure 7B.

[0081] In this specification, variables that take integer values ​​of 1 or more may be used as signs. For example, (p), which includes a variable p that takes an integer value of 1 or more, may be used as part of a sign that identifies any of up to p components. Also, for example, (m,n), which includes a variable m and a variable n that take integer values ​​of 1 or more, may be used as part of a sign that identifies any of up to m × n components.

[0082] <Example configuration of function panel 700 1> The functional panel described in this embodiment includes an optical element ML, an insulating film 573, and a region AP (see Figures 1A and 3A). The functional panel also includes a substrate 770 and a functional layer 520.

[0083] 《Example of ML optical element configuration》 The optical element ML has a refractive index N1 and is a convex lens (see Figures 1B and 3A). For example, materials with a refractive index between 1.5 and 1.8 can be used for the optical element ML. Specifically, a material with a refractive index of 1.56 can be used for the optical element ML.

[0084] The optical element ML has a plane TF and a plane BF, and the optical element ML has a plane XZ and a cross-section CRS1.

[0085] Surface TF traces a first curve in cross-section CRS1, and this first curve has a radius of curvature R1 (see Figure 3A).

[0086] Surface BF faces surface TF, and surface BF is irradiated with light PH. Furthermore, surface BF has an overlapping region with surface TF, and the light PH irradiated onto surface BF is focused towards surface TF.

[0087] 《Example of the configuration of insulating film 573》 The insulating film 573 is sandwiched between the optical element ML and region AP, and the insulating film 573 is in contact with surface BF. For example, the insulating film 573 can be made of a material with the same refractive index as the material used for the optical element ML. Specifically, a material with a refractive index of 1.5 to 1.8, for example, a material with a refractive index of 1.56, can be used for the insulating film 573.

[0088] 《Example of Domain AP Configuration》 Region AP overlaps with surface BF, region AP faces surface BF, and region AP emits light PH. Furthermore, region AP has a distance L1 between it and surface BF. Alternatively, region AP includes a region with surface BF between it and surface TF. For example, the region that emits light from a light-emitting element can be used as region AP.

[0089] The distance L1 has the relationship shown in equation (i) with respect to the radius of curvature R1 and the refractive index N1. The distance L1 is between 0.01 μm and 100 μm, preferably between 0.1 μm and 20 μm.

[0090] (Math 3) L1 ≤ 5 × R1 / (N1 - 1) (i)

[0091] For example, when the distance L1 is 2 μm, the radius of curvature R1 is 1.2 μm, and the refractive index N1 is 1.56, the brightness in front of region AP can be increased by 1.27 times compared to when there is no optical element ML.

[0092] This allows the optical PH emitted by the region AP to be focused in the direction in front of the region AP, or the optical PH emitted by the region AP to be utilized efficiently. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0093] <Example configuration of the 700 function panel 2> Another configuration of the functional panel described in this embodiment will be explained with reference to Figure 3B. Note that this configuration differs from the functional panel described with reference to Figures 1 and 3A in that it includes a sealing material 705. Here, the differences will be explained in detail, and the above explanation will be used in reference to the parts where a similar configuration can be used.

[0094] The functional panel comprises an optical element ML, an insulating film 573, a sealing material 705, and a region AP (see Figure 3B). The functional panel also has a base material 770.

[0095] 《Example of the composition of sealing material 705》 The encapsulant 705 is in contact with the surface TF, and the encapsulant 705 has a refractive index N2, which is smaller than the refractive index N1. For example, a material with a refractive index of 1.2 or more and 1.5 or less can be used for the encapsulant 705. Specifically, a material with a refractive index of 1.4 can be used for the optical element ML. Alternatively, the encapsulant 705 has the function of bonding the surface TF and the substrate 770.

[0096] 《Example of Domain AP Configuration 1》 Region AP overlaps with surface BF, region AP faces surface BF, and region AP emits light PH. Furthermore, region AP has a distance L1 between it and surface BF. Alternatively, region AP has a region between it and surface TF with surface BF in between.

[0097] The distance L1 has the relationship shown in equation (i) with respect to the radius of curvature R1, refractive index N1, and refractive index N2.

[0098] (Math 4) L1 ≤ 5 × R1 × N2 / (N1 - N2) (ii)

[0099] For example, when the distance L1 is 3 μm, the radius of curvature R1 is 1.2 μm, the refractive index N1 is 1.56, and the refractive index N2 is 1.40, the brightness in front of region AP can be increased by 1.51 times compared to when there is no optical element ML.

[0100] This allows the optical element ML to be protected from damage and scratches during use using the sealing material 705. Alternatively, the light PH emitted by the region AP can be focused in the direction in front of the region AP. Alternatively, the light PH emitted by the region AP can be utilized efficiently. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0101] <Example configuration of the 700 function panel 3> Furthermore, in one embodiment of the present invention, the functional panel has an optical element ML with a surface BF having an area S1 and a region AP having an area S2. Area S1 is greater than or equal to area S2.

[0102] This allows the light PH emitted by the region AP to be efficiently incident onto the optical element ML. Alternatively, the light PH emitted by the region AP can be focused in the direction in front of the region AP. Or, the light PH emitted by the region AP can be efficiently utilized. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0103] <Example configuration of the 700 function panel 4> Furthermore, a functional panel according to one embodiment of the present invention has 702G(i,j) pixels (see Figure 4A).

[0104] 《Example configuration of pixel 702G(i,j)》 Pixel 702G(i,j) is equipped with element 550G(i,j), which emits optical PHG (see Figures 4B and 4C). A colored film CF can be used for a portion of the insulating film 573.

[0105] 《Example of Domain AP Configuration 2》 Region AP includes element 550G(i,j), and optical PH includes optical PHG.

[0106] This allows the optical PHG emitted by pixel 702G(i,j) to be efficiently incident onto the optical element ML. Alternatively, the optical PHG emitted by region AP can be collected in the direction of the front of surface TF. Alternatively, the optical PHG emitted by region AP can be efficiently utilized. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0107] <Example configuration of the 700 function panel 5> Furthermore, a functional panel according to one embodiment of the present invention has a pair of pixels 703(i,j) (see Figures 5A and 6A).

[0108] 《Example configuration of pixel 703(i,j)》 A pair of pixels 703(i,j) includes pixels 702G(i,j) and pixels 702R(i,j).

[0109] Furthermore, pixel 702R(i,j) is equipped with element 550R(i,j), which emits optical PHR (see Figures 5B and 5C, and Figures 6B and 6C). For example, pixel 702G(i,j) can emit green optical PHG, and pixel 702R(i,j) can emit red optical PHR.

[0110] 《Example of Domain AP Configuration 3》 Region AP includes element 550R(i,j), and optical PH includes optical PHR. For example, if optical PH includes green PHG and red optical PHR, optical PH will appear yellow.

[0111] This allows the optical PHG and optical PHR emitted by a pair of pixels 703(i,j) to be efficiently incident onto the optical element ML. Alternatively, the optical PHG and optical PHR emitted by the region AP can be collected in the direction of the front of the surface TF. Alternatively, the optical PHG and optical PHR emitted by the region AP can be efficiently utilized. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0112] 《Example 2 of ML Optical Element Configuration》 The optical element ML has a plane YZ and a cross-section CRS2 (see Figures 4C, 5C, and 6C). The plane YZ intersects the plane XZ at axis Z. The plane TF traces a second curve in cross-section CRS2. For example, the plane containing region AP can be made into the plane XY, and the axis intersecting the plane XY can be made into axis Z.

[0113] The second curve is longer than the first curve and comprises a region. This region is either flat or has a radius of curvature R2, where R2 is greater than R1. For example, a curve comprising a flat region or a region with a radius of curvature R2 and having a radius of curvature R1 at its ends can be used as the second curve. Furthermore, a cylindrical lens can be used as the optical element ML.

[0114] This makes microfabrication easier in the direction of the other axis Y compared to the direction of the extension of one axis X. Alternatively, it facilitates the formation of optical elements ML. Alternatively, it allows the light PH emitted by region AP to be focused in the direction in front of region AP. Alternatively, it allows the light PH emitted by region AP to be utilized efficiently. As a result, it is possible to provide a novel functional panel with superior convenience, usefulness, or reliability.

For example, the first selection signal can be supplied using the conductive film G1(i) (see Figure 9B). Alternatively, the image signal can be supplied using the conductive film S1g(j). 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 18).

[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 (see Figure 10). The pixel circuit 530G(i,j) also includes node N22, capacitor C22, and switch SW23.

[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 element 550G(i,j) can be controlled using the potential of node N21. As a result, a novel functional panel with superior convenience and reliability can be provided.

[0136] 《Example Configuration of Element 550G(i,j) 1》 Element 550G(i,j) is electrically connected to the pixel circuit 530G(i,j) (see Figure 9A).

[0137] For example, organic electroluminescent elements, inorganic electroluminescent elements, light-emitting diodes, or QDLEDs (Quantum Dot LEDs) can be used for element 550G(i,j).

[0138] <Example configuration of the 700 function panel 2> The functional panel described in this embodiment includes conductive film RS(i), conductive film TX(i), conductive film SE(i), conductive film VR, conductive film VCP, conductive film VPI, and conductive film WX(j) (see Figure 11).

[0139] For example, conductive film RS(i) is supplied with a third selection signal, conductive film TX(i) is supplied with a fourth selection signal, and conductive film SE(i) is supplied with a fifth selection signal.

[0140] 《Example of pixel 703(i,j) configuration 2》 Pixel 703(i,j) includes pixel 702S(i,j) (see Figure 8B). Pixel 702S(i,j) includes pixel circuit 530S(i,j) and element 550S(i,j) (see Figure 9A).

[0141] 《Example Configuration 1 of Pixel Circuit 530S(i,j)》 The pixel circuit 530S(i,j) includes switches SW31, SW32, SW33, transistor M31, capacitor C31, and node FD (see Figure 11A).

[0142] Switch SW31 has a first terminal electrically connected to element 550S(i,j), a second terminal electrically connected to node FD, and a function to control the conduction state or non-conduction state based on the potential of the conductive film TX(i).

[0143] 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).

[0147] This allows the imaging signal generated by element 550S(i,j) to be transferred to node FD using switch SW31. Alternatively, the imaging signal generated by element 550S(i,j) can be stored in node FD using switch SW31. Alternatively, the connection between pixel circuit 530S(i,j) and element 550S(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 or reliability can be provided.

[0148] 《Example Configuration 1 of Element 550S(i,j)》 Element 550S(i,j) is electrically connected to the pixel circuit 530S(i,j) (see Figure 9A). Element 550S(i,j) has the function of generating an imaging signal. For example, heterojunction photoelectric elements, bulk heterojunction photoelectric elements, etc., can be used for element 550S(i,j).

[0149] 《Example of pixel 703(i,j) configuration 3》 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.

[0150] 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.

[0151] 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 8B).

[0152] 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).

[0153] Furthermore, for example, a pixel that emits infrared light can be used in addition to the above set for pixel 703(i,j). Specifically, a pixel that emits light including light with wavelengths between 650nm and 1000nm can be used for pixel 703(i,j).

[0154] <Example configuration of the 700 function panel 3> The functional panel described in this embodiment includes a drive circuit GD, a drive circuit SD, and a drive circuit RD (see Figure 8A).

[0155] Example configuration of the drive circuit GD The drive circuit GD has the function of supplying a first selection signal and a second selection signal. For example, the drive circuit GD is electrically connected to the conductive film G1(i) and supplies the first selection signal, and is electrically connected to the conductive film G2(i) and supplies the second selection signal.

[0156] 《Example configuration of the SD drive circuit》 The drive circuit SD has the function of supplying image signals and control signals, and the control signals include a first level and a second level. For example, the drive circuit SD is electrically connected to the conductive film S1g(j) to supply image signals and is electrically connected to the conductive film S2g(j) to supply control signals.

[0157] 《Example configuration of drive circuit RD》 The drive circuit RD has the function of supplying a third to a fifth selection signal. For example, the drive circuit RD is electrically connected to the conductive film RS(i) and supplies a third selection signal, electrically connected to the conductive film TX(i) and supplies a fourth selection signal, and electrically connected to the conductive film SE(i) and supplies a fifth selection signal.

[0158] <Example configuration of the 700 function panel 4> The functional panel described in this embodiment has a conductive film VLEN, a conductive film VIV, and a readout circuit RC (see Figure 8A). Note that the readout circuit RC includes a readout circuit RC(j). Furthermore, a functional panel according to one aspect of the present invention has a conductive film CL, a conductive film CAPSEL, a conductive film CDSBIAS, a conductive film CDSVDD, a conductive film CDSVSS, and a conductive film VCL.

[0159] 《Example configuration of the readout circuit RC(j)》 The readout circuit RC(j) includes an amplification circuit and a sampling circuit SC(j) (see Figures 12A and 12B).

[0160] Example of an amplification circuit configuration The amplification circuit includes a transistor M32(j) (see Figure 12A). 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.

[0161] When switch SW33 is in the conductive state, the conductive film WX(j) connects transistors M31 and M32 (see Figures 11 and 12A). This allows a source follower circuit to be constructed using transistors M31 and M32. Alternatively, the potential of the conductive film WX(j) can be changed based on the potential of node FD.

[0162] 《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 12B). It also includes a node NS.

[0163] 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).

[0164] 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. The difference signal of the pixel circuit 530S(i,j) can be acquired for each conductive film WX(j). Alternatively, noise can be reduced. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0165] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0171] <Example configuration of function panel 700 1> The functional panel described in this embodiment has a functional layer 520 (see Figure 13).

[0172] 《Example Configuration of Functional Layer 520 1》 The functional layer 520 includes a pixel circuit 530G(i,j) (see Figure 13). The functional layer 520 includes, for example, a transistor M21 used in the pixel circuit 530G(i,j) (see Figures 3 and 14A).

[0173] The functional layer 520 includes an aperture 591G. The pixel circuit 530G(i,j) is electrically connected to element 550G(i,j) at aperture 591G (see Figures 13 and 14A).

[0174] 《Example Configuration of Functional Layer 520 2》 The functional layer 520 includes a pixel circuit 530S(i,j) (see Figure 13). The functional layer 520 includes, for example, a transistor used in the switch SW31 of the pixel circuit 530S(i,j) (see Figures 13 and 15A).

[0175] The functional layer 520 is provided with an aperture 591S, and the pixel circuit 530S(i,j) is electrically connected to the element 550S(i,j) at the aperture 591S (see Figures 13 and 15A).

[0176] This allows the pixel circuit 530G(i,j) to be formed on the functional layer 520. Alternatively, the pixel circuit 530S(i,j) can be formed on the functional layer 520. For example, in the process of forming the semiconductor film used for the pixel circuit 530G(i,j), the semiconductor film used for the pixel circuit 530S(i,j) can be formed. Alternatively, the manufacturing process can be simplified. As a result, a novel functional panel with superior convenience, usefulness, or reliability can be provided.

[0177] 《Example 3 of Functional Layer 520 Configuration》 The functional layer 520 includes a drive circuit GD (see Figures 8A and 13). The functional layer 520 includes, for example, a transistor MD used in the drive circuit GD (see Figures 13 and 16A).

[0178] The functional layer 520 includes a drive circuit RD and a readout circuit RC (see Figure 13).

[0179] This allows, for example, the semiconductor film used for the drive circuit GD to be formed in the process of forming the semiconductor film used for the pixel circuit 530G(i,j). Alternatively, for example, the semiconductor films used for the drive circuit RD and the readout circuit RC 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.

[0180] Examples of transistor configurations Bottom-gate or top-gate transistors can be used in the functional layer 520. Specifically, transistors can be used as switches.

[0181] The transistor comprises a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see Figure 14B).

[0182] 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.

[0183] The conductive film 504 has a region that overlaps with region 508C, and the conductive film 504 has the function of a gate electrode.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 《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.

[0189] [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.

[0190] [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.

[0191] Alternatively, for example, the reliability of the transistor can be improved compared to a transistor using hydrogenated amorphous silicon as the semiconductor film 508.

[0192] Alternatively, the temperature required for transistor fabrication can be lowered compared to, for example, transistors using single-crystal silicon.

[0193] 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.

[0194] [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.

[0195] 《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. In addition, power consumption associated with operation can be reduced.

[0196] Furthermore, compared to pixel circuits using transistors with amorphous silicon as the semiconductor film, the pixel circuit can hold the imaging signal for a longer period of time. Specifically, the fourth 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. In addition, moving subjects can be photographed with reduced distortion.

[0197] For example, transistors using oxide semiconductors can be used. Specifically, oxide semiconductors containing indium, oxide semiconductors containing indium, gallium, and zinc, or oxide semiconductors containing indium, gallium, zinc, and tin. It can be used in semiconductor films.

[0198] 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.

[0199] For example, a 25 nm thick film containing indium, gallium, and zinc can be used as the semiconductor film 508.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] This can suppress display flicker, 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.

[0205] 《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.

[0206] For example, organic semiconductors can be used as semiconductors in transistors. Specifically, organic semiconductors containing polyacenes or graphene can be used as semiconductor films.

[0207] 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.

[0208] For example, a conductive film used for the source or drain electrode of a transistor, a conductive film used for the gate electrode, and an insulating film used for the gate insulating film can be used as capacitance.

[0209] 《Example Configuration of Functional Layer 520 2》 The functional layer 520 comprises insulating film 521, insulating film 518, insulating film 516, insulating film 506, insulating film 501C, etc. (see Figures 14A and 14B).

[0210] The insulating film 521 includes a region sandwiched between the pixel circuit 530G(i,j) and the element 550G(i,j).

[0211] The insulating film 518 includes a region sandwiched between the insulating film 521 and the insulating film 501C.

[0212] The insulating film 516 includes a region sandwiched between the insulating film 518 and the insulating film 501C.

[0213] The insulating film 506 includes a region sandwiched between the insulating film 516 and the insulating film 501C.

[0214] [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.

[0215] 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.

[0216] For example, films containing silicon oxide films, silicon nitride films, silicon oxynitride films, aluminum oxide films, or laminated materials comprising a plurality of these selected from each other can be used as the insulating film 521. Note that silicon nitride films are dense films and have excellent function in suppressing the diffusion of impurities.

[0217] For example, the insulating film 521 can be made from polyester, polyolefin, polyamide, polyimide, polycarbonate, polysiloxane, or acrylic resin, or from laminated or composite materials of multiple resins selected from these. Incidentally, polyimide has superior properties compared to other organic materials in terms of thermal stability, insulation, toughness, low dielectric constant, low thermal expansion coefficient, and chemical resistance. For this reason, polyimide can be particularly suitable for use in the insulating film 521.

[0218] Alternatively, the insulating film 521 may be formed using a photosensitive material. Specifically, a film formed using a photosensitive polyimide or a photosensitive acrylic resin can be used as the insulating film 521.

[0219] As a result, the insulating film 521 can flatten steps caused by various structures that overlap it, for example.

[0220] [Insulation film 518] For example, a material that can be used for insulating film 521 can be used for insulating film 518.

[0221] 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.

[0222] [Insulating film 516] For example, a material that can be used for insulating film 521 can be used for insulating film 516.

[0223] Specifically, a film manufactured using a different method than that used for the insulating film 518 can be used for the insulating film 516.

[0224] [Insulator 506] For example, a material that can be used for insulating film 521 can be used for insulating film 506.

[0225] 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.

[0226] [Insulating film 501D] The insulating film 501D includes a region sandwiched between the insulating film 501C and the insulating film 516.

[0227] For example, a material that can be used for insulating film 506 can be used for insulating film 501D.

[0228] [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 the pixel circuit, element 550G(i,j) or element 550S(i,j), etc.

[0229] 《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.

[0230] [Wiring etc.] For example, inorganic conductive materials, organic conductive materials, metals, or conductive ceramics can be used for wiring, etc.

[0231] 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.

[0232] 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.

[0233] 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.

[0234] Specifically, films containing graphene or graphite can be used for wiring and the like.

[0235] 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.

[0236] For example, a film containing metal nanowires can be used for wiring and the like. Specifically, nanowires containing silver can be used.

[0237] Specifically, conductive polymers can be used in wiring and other applications.

[0238] For example, terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material (see Figure 13). Specifically, terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material CP.

[0239] <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 14A). The functional panel 700 also comprises a structure KB.

[0240] 《Base material 510, base material 770》 A translucent material can be used for the base material 510 or the base material 770.

[0241] 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.

[0242] For example, materials with a thickness of 0.7 mm or less and 0.1 mm or more can be used. Specifically, materials polished to a thickness of about 0.1 mm can be used. This allows for a reduction in weight.

[0243] 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.

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0248] 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 resins having siloxane bonds, such as polyester, polyolefin, polyamide (nylon, aramid, etc.), polyimide, polycarbonate, polyurethane, acrylic resin, epoxy resin, or silicone, 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.

[0249] 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.

[0250] For example, a composite material obtained by laminating a film such as a metal plate, a thin glass plate or an inorganic material, and a resin film or the like can be used for the base material 510 or the base material 770. For example, a composite material in which fibrous or particulate metal, glass, inorganic material or the like is dispersed in a resin can be used for the base material 510 or the base material 770. For example, a composite material in which fibrous or particulate resin or organic material or the like is dispersed in an inorganic material can be used for the base material 510 or the base material 770.

[0251] In addition, a single-layer material or a material with a plurality of layers laminated thereon can be used for the base material 510 or the base material 770. For example, a material with an insulating film or the like laminated thereon can be used. Specifically, a material with one or more films selected from a silicon oxide layer, a silicon nitride layer, a silicon oxynitride layer or the like laminated thereon can be used. Thereby, for example, diffusion of impurities contained in the base material can be prevented. Or, diffusion of impurities contained in glass or resin can be prevented. Or, diffusion of impurities permeating through the resin can be prevented.

[0252] In addition, paper, wood or the like can be used for the base material 510 or the base material 770.

[0253] For example, a material having heat resistance sufficient to withstand heat treatment during the manufacturing process can be used for the base material 510 or the base material 770. Specifically, a material having heat resistance to the heat applied during the manufacturing process of directly forming a transistor, a capacitor or the like can be used for the base material 510 or the base material 770.

[0254] For example, an insulating film, a transistor, a capacitor or the like is formed on a process substrate having heat resistance to the heat applied during the manufacturing process, and the formed insulating film, transistor, capacitor or the like is transferred to, for example, the base material 510 or the base material 770. Thereby, for example, an insulating film, a transistor, a capacitor or the like can be formed on a flexible substrate.

[0255] 《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 14A).

[0256] Inorganic materials, organic materials, or composite materials of inorganic and organic materials can be used as the sealing material 705.

[0257] For example, an organic material such as a heat-meltable resin or a curable resin can be used as the sealing material 705.

[0258] For example, organic materials such as reaction-curing adhesives, photocuring adhesives, thermosetting adhesives, and / or anaerobic adhesives can be used in the encapsulant 705.

[0259] 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.

[0260] 《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.

[0261] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0262] (Embodiment 4) In this embodiment, the configuration of a functional panel according to one aspect of the present invention will be described with reference to Figures 14A to 15B.

[0263] <Example configuration of function panel 700 1> The functional panel 700 includes element 550G(i,j) and element 550S(i,j) (see Figure 13).

[0264] 《Example Configuration of Element 550G(i,j) 1》 Element 550G(i,j) comprises electrodes 551G(i,j), electrode 552, and layer 553G(j) containing a light-emitting material (see Figure 14A). The layer 553G(j) containing the light-emitting material also includes a region sandwiched between electrodes 551G(i,j) and electrode 552.

[0265] [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.

[0266] 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.

[0267] [Example 2 of the composition of layer 553G(j) containing luminescent material] For example, a laminated material that is stacked to emit white light can be used in layer 553G(j) which contains a light-emitting material.

[0268] Specifically, multiple materials that emit light of different hues can be used in layer 553G(j) which contains the luminescent material.

[0269] For example, a laminated material comprising a layer containing a light-emitting 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 light-emitting material layer 553G(j). Alternatively, a laminated material comprising a layer containing a light-emitting 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 light-emitting material layer 553G(j).

[0270] 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.

[0271] [Configuration Example 3 of Layer 553G(j) Containing Light-Emitting Material] For example, a laminated material laminated to emit blue light or ultraviolet light can be used for the layer 553G(j) containing a light-emitting material. Also, for example, a color conversion layer can be used in a stacked manner.

[0272] [Configuration Example 4 of Layer 553G(j) Containing Light-Emitting Material] The layer 553G(j) containing a light-emitting material includes a light-emitting unit. The light-emitting unit has one region where electrons injected from one side recombine with holes injected from the other side. The light-emitting unit also contains a light-emitting material, and the light-emitting material emits the energy generated by the recombination of electrons and holes as light. Note that a hole transport layer and an electron transport layer can be used for the light-emitting unit. The hole transport layer is disposed closer to the positive electrode side than the electron transport layer, and the hole transport layer has a higher hole mobility than the electron transport layer.

[0273] For example, a plurality of light-emitting units and an intermediate layer can be used for the layer 553G(j) containing a light-emitting material. The intermediate layer has a region sandwiched between two light-emitting units. The intermediate layer has a charge generation region, and the intermediate layer has a function of supplying holes to the light-emitting unit disposed on the cathode side and supplying electrons to the light-emitting unit disposed on the anode side. Note that a configuration including a plurality of light-emitting units and an intermediate layer may be referred to as a tandem-type light-emitting device.

[0274] Thereby, the current efficiency related to light emission can be increased. Or, at the same luminance, the current density flowing through the light-emitting device can be decreased. Or, the reliability of the light-emitting device can be increased.

[0275] 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.

[0276] 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.

[0277] [Electrode 551G(i,j), electrode 552] For example, materials that can be used for wiring can be used for electrode 551G(i,j) or electrode 552. Specifically, materials that are transparent to visible light can be used for electrode 551G(i,j) or electrode 552.

[0278] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, gallium-doped zinc oxide, etc., can be used. Alternatively, a thin metal film that allows light to pass through can be used. Or, a material that is transparent to visible light can be used.

[0279] For example, a metal film that transmits some light and reflects other parts of it can be used for electrode 551G(i,j) or electrode 552. For example, the distance between electrode 551G(i,j) and electrode 552 can be adjusted using a layer 553G(j) containing a light-emitting material.

[0280] This allows a micro-resonator structure to be provided in element 550G(i,j). Alternatively, it allows light of a predetermined wavelength to be extracted more efficiently than other light. Alternatively, it allows light with a narrow spectral full width at half maximum to be extracted. Alternatively, it allows light of vivid colors to be extracted.

[0281] For example, a film that efficiently reflects light can be used for electrode 551G(i,j) or electrode 552. Specifically, a material containing silver and palladium, or a material containing silver and copper, can be used for the metal film.

[0282] Furthermore, electrode 551G(i,j) is electrically connected to pixel circuit 530G(i,j) at aperture 591G (see Figure 15A). Electrode 551G(i,j) overlaps, for example, with an aperture formed in insulating film 528, and electrode 551G(i,j) is provided with insulating film 528 around its periphery.

[0283] This prevents short circuits between electrodes 551G(i,j) and 552.

[0284] 《Example Configuration 1 of Element 550S(i,j)》 Element 550S(i,j) comprises electrodes 551S(i,j), electrode 552, and a layer 553S(j) containing a photoelectric conversion material (see Figure 15A). Electrode 551S(i,j) is electrically connected to the pixel circuit 530S(i,j), and electrode 552 is electrically connected to the conductive film VPD (see Figure 11). Furthermore, electrode 552 used in element 550G(i,j) can be used in element 550S(i,j). This simplifies the configuration and manufacturing process of the functional panel.

[0285] For example, heterojunction photoelectric elements, bulk heterojunction photoelectric elements, etc., can be used in element 550S(i,j).

[0286] [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 device 550S(i,j) that uses such a multilayer film structure in layer 553S(j) containing the photoelectric conversion material can be called a PN-type photodiode.

[0287] 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 device 550S(i,j) using such a laminated film structure in layer 553S(j) containing the photoelectric conversion material can be called a PIN-type photodiode.

[0288] 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. An element 550S(i,j) using such a laminated film structure in layer 553S(j) containing the photoelectric conversion material can be called an avalanche photodiode.

[0289] [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.

[0290] 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.

[0291] Specifically, the hole transport layer used in layer 553G(j) containing the light-emitting material can be used in layer 553S(j) containing the photoelectric conversion material. Alternatively, the electron transport layer used in layer 553G(j) containing the light-emitting material can be used in layer 553S(j) containing the photoelectric conversion material. Alternatively, both the hole transport layer and the electron transport layer can be used in layer 553S(j) containing the photoelectric conversion material.

[0292] This allows for the formation of a hole transport layer for layer 553S(j) containing a photoelectric conversion material in the process of forming a hole transport layer for layer 553G(j) containing a light-emitting material. Alternatively, it allows for the formation of an electron transport layer for layer 553S(j) containing a photoelectric conversion material in the process of forming an electron transport layer for layer 553G(j) containing a light-emitting material. Alternatively, the manufacturing process can be simplified.

[0293] 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.

[0294] For example, a fullerene derivative that dissolves or disperses in the first solvent can be used in layer 553S(i,j) containing the photoelectric conversion material. Specifically, [6,6]-Phenyl-C71-butyric acid methyl ester (abbreviated as PC70BM), [6,6]-Phenyl-C61-butyric acid methyl ester (abbreviated as PC60BM), 1′,1′′,4′,4′′-Tetrahydro-di[1,4]methanonaphthaleno[1,2:2′,3′,56,60:2′′,3′′][5,6]fullerene-C60 (abbreviated as ICBA), etc., can be used in layer 553S(i,j) containing the photoelectric conversion material.

[0295] Furthermore, electron-donating organic semiconductor materials such as copper(II) phthalocyanine (CuPc) or tetraphenyldibenzoperiflanthene (DBP) can be used in p-type semiconductor films.

[0296] For example, a π-conjugated organic polymer material, oligomer, or low molecular weight material that is dissolved or dispersed in the first solvent can be used in layer 553S(i,j) containing the photoelectric conversion material. Specifically, polyphenylene vinylene-based materials or polythiophene-based materials can be used in layer 553S(i,j) containing the photoelectric conversion material. Specifically, Poly([2,6′-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,3-b]dithiophene]{3-fluoro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (abbreviated as PTB7-Th), Poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (abbreviated as PYB7), Poly(3-hexylthiophene-2,5-diyl) (abbreviated as P3HT), etc., can be used in layer 553S(i,j) containing the photoelectric conversion material.

[0297] 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.

[0298] <Example configuration of the 700 function panel 2> The functional panel 700 has insulating film 528 and insulating film 573 (see Figure 14A).

[0299] 《Insulating Film 528》 The insulating film 528 has a region sandwiched between the functional layer 520 and the substrate 770, and the insulating film 528 has an opening in the region overlapping with elements 550G(i,j) and 550S(i,j) (see Figure 14A).

[0300] For example, a material 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 acrylic resin, or a film containing polyimide can be used for the insulating film 528.

[0301] 《Insulating film 573》 The insulating film 573 includes a region that sandwiches elements 550G(i,j) and 550S(i,j) between itself and the functional layer 520 (see Figure 14A).

[0302] For example, a single film or a multilayer film formed by stacking multiple films can be used as the insulating film 573. Specifically, a multilayer film can be used as the insulating film 573, which consists of an insulating film 573A that can be formed in a way that does not easily damage elements 550G(i,j) and 550S(i,j), and a dense insulating film 573B with few defects.

[0303] This makes it possible to suppress the diffusion of impurities into elements 550G(i,j) and 550S(i,j). Alternatively, it can improve the reliability of elements 550G(i,j) and 550S(i,j).

[0304] <Example configuration of the 700 function panel 3> The functional panel 700 includes a functional layer 720 (see Figure 14A).

[0305] Functional Layer 720 The functional layer 720 comprises a light-shielding film BM, a colored film CF(G), and an insulating film 771. A color conversion layer may also be used.

[0306] 《Light blocking film BM》 The light-shielding film BM has an aperture in the region overlapping with pixel 702G(i,j). Additionally, the light-shielding film BM has an aperture in the region overlapping with pixel 702S(i,j).

[0307] For example, dark-colored materials can be used in the light-shielding film BM. This can improve the contrast of the display.

[0308] 《Colored film CF(G)》 The colored film CF(G) comprises a region sandwiched between the substrate 770 and the element 550G(i,j). For example, a material that selectively transmits light of a predetermined color can be used for the colored film CF(G). Specifically, a material that transmits red light, green light, or blue light can be used for the colored film CF(G).

[0309] 《Example of the configuration of insulating film 771》 The insulating film 771 includes a region sandwiched between the substrate 770 and the element 550G(i,j).

[0310] The insulating film 771 includes a region between it and the substrate 770 in which a light-shielding layer BM, a colored film CF(G), or a color conversion layer is sandwiched. This makes it possible to flatten the irregularities caused by the thickness of the light-shielding layer BM, the colored film CF(G), or the color conversion layer.

[0311] Color conversion layer The color conversion layer comprises a region sandwiched between the substrate 770 and the element 550G(i,j).

[0312] For example, a material that emits light with a wavelength longer than the wavelength of the incident light can be used as the color conversion layer. For instance, a material that absorbs blue or ultraviolet light and converts it into green light and emits it, a material that absorbs blue or ultraviolet light and converts it into red light and emits it, or a material that absorbs ultraviolet light and converts it into blue light and emits it can be used as the color conversion layer. Specifically, quantum dots with a diameter of several nanometers can be used as the color conversion layer. This makes it possible to emit light with a narrow full width at half maximum spectrum, or to emit highly saturated light.

[0313] <Example configuration of the 700 function panel 4> The functional panel 700 is equipped with a light-shielding film KBM (see Figure 14A).

[0314] 《Light blocking film KBM》 The light-shielding film KBM has an opening in the region overlapping with the pixel 702S(i,j). Furthermore, the light-shielding film KBM has a region sandwiched between the functional layer 520 and the substrate 770, providing a predetermined gap between the functional layer 520 and the substrate 770. For example, a dark-colored material can be used for the light-shielding film KBM. This makes it possible to suppress stray light entering the pixel 702S(i,j).

[0315] <Example configuration of the 700 function panel 5> The functional panel 700 includes a functional film 770P, etc. (see Figure 14A).

[0316] 《Functional membrane 770P, etc.》 The functional film 770P has a region that overlaps with element 550G(i,j).

[0317] 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.

[0318] 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.

[0319] For example, a circularly polarizing film can be used in the functional film 770P.

[0320] 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.

[0321] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0322] (Embodiment 5) In this embodiment, the configuration of a functional panel according to one aspect of the present invention will be described with reference to Figures 17A to 18.

[0323] Figure 17A is a block diagram illustrating the configuration of a functional panel according to one embodiment of the present invention, and Figure 17B is a block diagram illustrating a part of Figure 17A.

[0324] Figure 18 is a diagram illustrating the operation of a functional panel according to one embodiment of the present invention.

[0325] <Example configuration of function panel 700 1> The functional panel 700 described in this embodiment has a region 231 (see Figure 17A).

[0326] 《Example of configuration for area 231》 Region 231 comprises a group of one set of pixels 703(i,1) to one set of pixels 703(i,n) and another group of one set of pixels 703(1,j) to one set of pixels 703(m,j). Region 231 also comprises conductive films G1(i), TX(i), S1g(j), and WX(j).

[0327] A group of pixels 703(i,1) to a group of pixels 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 a group of pixels 703(i,n) includes a pair of pixels 703(i,j).

[0328] Furthermore, a group of pixels 703(i,1) to a group of pixels 703(i,n) are electrically connected to the conductive film G1(i). Also, a group of pixels 703(i,1) to a group of pixels 703(i,n) are electrically connected to the conductive film TX(i).

[0329] Another group of pixels, from a set of pixels 703(1,j) to a set of pixels 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, from a set of pixels 703(1,j) to a set of pixels 703(m,j), includes a set of pixels 703(i,j).

[0330] Furthermore, a pair of pixels 703(1,j) or a pair of pixels 703(m,j) in another group are electrically connected to the conductive film S1g(j). Also, a pair of pixels 703(1,j) or a pair of pixels 703(m,j) in another group are electrically connected to the conductive film WX(j).

[0331] This allows image information to be supplied to multiple pixels, or imaging information to be acquired from multiple pixels. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0332] 《Example of configuration for area 231 2》 Region 231 comprises a group of pixels of 500 or more per inch. It also comprises a group of pixels of 1000 or more per inch, preferably 5000 or more, and more preferably 10000 or more. A group of pixels includes pixel 703(i,j).

[0333] 《Example of configuration for area 231 3》 Region 231 contains multiple pixels arranged in a matrix. For example, region 231 contains 7600 or more pixels in the row direction and 4300 or more pixels in the column direction. Specifically, it contains 7680 pixels in the row direction and 4320 pixels in the column direction.

[0334] This allows for the display of high-resolution images. As a result, it is possible to provide a new functional panel that is superior in terms of convenience and reliability.

[0335] 《Example of configuration for area 231 4》 Region 231 has a diagonal length of 40 inches or more, preferably 60 inches or more. Preferably, it is 80 inches or more. Also, the diagonal length of area 231 is, for example, 15 A length of 0 inches or less is preferable because it allows for lighter weight.

[0336] This allows for the display of immersive images. As a result, it is possible to provide a new functional panel that is superior in terms of convenience and reliability.

[0337] <Example configuration of the 700 function panel 2> Furthermore, a functional panel 700 in one embodiment of the present invention includes a group of sampling circuits SC, a multiplexer MUX, an amplification circuit AMP, and an analog-to-digital conversion circuit ADC (see Figure 17A). The group of sampling circuits SC includes a sampling circuit SC(j).

[0338] This allows a sampling circuit SC(j) to 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 or reliability can be provided.

[0339] 《Example configuration of a multiplexer MUX》 The multiplexer MUX has the function of selecting one sampling circuit from a group to acquire the imaging signal. For example, the multiplexer MUX selects sampling circuit SC(j) to acquire the imaging signal.

[0340] Specifically, the multiplexer MUX is electrically connected to sampling circuits SC(1) through SC(9), and selects one to acquire the imaging signal (see Figure 17B). For example, it is electrically connected to the third terminal OUT(9) of sampling circuit SC(9).

[0341] Furthermore, the multiplexer MUX is electrically connected to the amplification circuit AMP and has the function of supplying the acquired imaging signal.

[0342] This allows for the selection of a predetermined pixel from multiple pixels arranged in the row direction, or the acquisition of imaging information from a predetermined pixel. Alternatively, it allows for the suppression of the number of imaging signals acquired simultaneously by using multiple multiplexers. Furthermore, it enables the use of an analog-to-digital converter (ADC) with fewer input channels compared to the number of pixels arranged in the row direction. As a result, a novel functional panel with superior convenience, usefulness, and reliability can be provided.

[0343] Example of an amplifier circuit (AMP) configuration The amplification circuit (AMP) can amplify the imaging signal and supply it to the analog-to-digital conversion circuit (ADC).

[0344] The functional layer 520 includes a multiplexer (MUX) and an amplification circuit (AMP).

[0345] This allows, for example, the formation of semiconductor films used in the pixel circuit 530G(i,j) to be used in the process of forming the semiconductor film used in the multiplexer MUX and the amplifier circuit AMP. 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.

[0346] Example of Analog-to-Digital Converter (ADC) Configuration An analog-to-digital converter (ADC) has the function of converting analog imaging signals into digital signals. This suppresses the degradation of the imaging signal during transmission.

[0347] <Example configuration of the 700 function panel 3> Furthermore, a functional panel 700 according to one embodiment of the present invention includes a drive circuit GD, a drive circuit RD, and a pair of pixels 703(i,j). The drive circuit GD has the function of supplying a first selection signal, and the drive circuit RD has the function of supplying a fourth selection signal and a fifth selection signal.

[0348] 《Example of pixel 703(i,j) configuration 1》 A pair of pixels 703(i,j) are supplied with a fourth and a fifth selection signal during periods when the first selection signal is not supplied (see Figure 18). The pixel circuit 530S(i,j) acquires an imaging signal based on the fourth selection signal and supplies an imaging signal based on the fifth selection signal.

[0349] For example, the conductive film G1(i) can be used to supply the first selection signal, the conductive film TX(i) can be used to supply the fourth selection signal, and the conductive film SE(i) can be used to supply the fifth selection signal (see Figure 11).

[0350] Furthermore, the operation of supplying a fourth selection signal and causing the pixel circuit 530S(i,j) to acquire the imaging signal can be called "imaging" (see Figure 18). Also, the operation of reading the imaging signal from the pixel circuit 530S(i,j) can be called "readout". In addition, the operation of supplying a predetermined voltage to the element 550S(i,j) can be called "initialization", the operation of exposing the element 550S(i,j) to light for a predetermined period after initialization can be called "exposure", and the operation of reflecting the voltage that has changed due to exposure to the pixel circuit 530S(i,j) can be called "transfer". Also, 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 an imaging signal.

[0351] 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.

[0352] 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.

[0353] 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.

[0354] 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.

[0355] 《Example of pixel 703(i,j) configuration 2》 Pixel 703(i,j) is supplied with a fourth 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 element 550G(i,j) (see Figure 18). 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 fourth selection signal.

[0356] This allows the intensity of light emitted by 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 element 550S(i,j). Alternatively, the subject can be imaged using element 550S(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.

[0357] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0358] (Embodiment 6) In this embodiment, the configuration of a display device according to one aspect of the present invention will be described with reference to Figures 19A to 19D.

[0359] Figure 19A is a block diagram of a display device according to one embodiment of the present invention, and Figures 19B to 19D are perspective views illustrating the external appearance of a display device according to one embodiment of the present invention.

[0360] <Example of display device configuration> The display device described in this embodiment includes a control unit 238 and a function panel 700 (see Figure 19A).

[0361] 《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.

[0362] The control unit 238 generates information based on image information VI, and the control unit 238 generates control signals based on control information CI. The control unit 238 also supplies information and control signals.

[0363] For example, the information includes 8 bits or more, preferably 12 bits or more, for 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.

[0364] 《Example of configuration of the control unit 238 2》 For example, the stretching circuit 234 and the image processing circuit 235 can be used in the control unit 238.

[0365] 《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.

[0366] 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.

[0367] The image processing circuit 235 includes, for example, a function to correct image information VI based on a predetermined characteristic curve to generate information, and a function to supply information.

[0368] 《Example Configuration of Function Panel 700 1》 The function panel 700 is supplied with information and control signals. For example, the function panel 700 described in any one of Embodiments 1 to 5 can be used.

[0369] 《Example of pixel 703(i,j) configuration 3》 Pixel 703(i,j) is displayed based on the information.

[0370] This allows image information VI to be displayed using element 550G(i,j). As a result, a novel display device with superior convenience, usefulness, or reliability can be provided. Alternatively, for example, an information terminal (see Figure 19B), a video display system (see Figure 19C), or a computer (see Figure 19D) can be provided.

[0371] 《Example Configuration of Function Panel 700 2》 For example, the function panel 700 includes a drive circuit and a control circuit.

[0372] 《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 (see Figure 19A).

[0373] 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.

[0374] 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, and can supply image signals.

[0375] 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 third to a fifth selection signal.

[0376] 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.

[0377] Control circuit A control circuit has the function of generating and supplying control signals. For example, clock signals or timing signals can be used as control signals.

[0378] Specifically, a control circuit formed on a rigid substrate can be used in a 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.

[0379] For example, the timing controller 233 can be used in the control circuit. Furthermore, the operation of the drive circuit RD and the readout circuit RC can be synchronized using the control circuit 243.

[0380] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0381] (Embodiment 7) In this embodiment, the configuration of an input / output device according to one aspect of the present invention will be described with reference to Figures 20 to 22D.

[0382] Figure 20 is a block diagram illustrating the configuration of an input / output device according to one embodiment of the present invention.

[0383] Figure 21A is a perspective view of an input / output device according to one embodiment of the present invention, Figures 21B and 21C are cross-sectional views illustrating a part of Figure 21A, and Figure 21D is an electrical resistance-stress curve schematically illustrating the characteristics of the detector.

[0384] Figure 22A is a perspective view of a component used in an input / output device according to one embodiment of the present invention, Figures 22B and 22C are cross-sectional views illustrating a part of Figure 21A, and Figure 22D is a stress-strain curve schematically illustrating the characteristics of a structure that undergoes jump-and-buckling.

[0385] <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 20).

[0386] 《Example of the configuration of the display unit 230 1》 The display unit 230 includes a function panel 700. For example, the function panel 700 described in any one of Embodiments 1 to 5 can be used in the display unit 230. A configuration having an input unit 240 and a display unit 230 can be referred to as a function panel 700TP.

[0387] 《Example of the configuration of the input unit 240 1》 The input unit 240 is equipped with a detection area 241. The input unit 240 detects objects that are close to the detection area 241.

[0388] The detection area 241 includes an area that overlaps with pixel 703(i,j).

[0389] This allows for the detection of objects approaching an area overlapping with the display unit 230 while displaying image information using the display unit 230. Alternatively, position information can be input by using a finger or other object brought close to the display unit 230 as a pointer. Or, position information can be associated with the image information displayed on the display unit 230. As a result, a novel input / output device with superior convenience, usefulness, and reliability can be provided.

[0390] 《Example of configuration of detection area 241 1》 The detection area 241 includes, for example, one or more detectors.

[0391] 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.

[0392] A group of detectors 802(g,1) through 802(g,q) includes detector 802(g,h), is arranged in the row direction (indicated by arrow R2 in the figure), and is electrically connected to wiring CL(g). The direction indicated by arrow R2 may be the same as or different from the direction indicated by arrow R1.

[0393] Furthermore, another group of detectors 802(1,h) to detectors 802(p,h) include detector 802(g,h), are arranged in the column direction intersecting the row direction (indicated by arrow C2 in the figure), and are electrically connected to wiring ML(h).

[0394] 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.

[0395] Specifically, capacitive proximity sensors, electromagnetic induction proximity sensors, optical proximity sensors, and resistive proximity sensors can be used as detectors.

[0396] Furthermore, multiple types of detectors can be used in combination. For example, a finger detector and a stylus pen detector can be used together.

[0397] 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.

[0398] 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.

[0399] 《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 20).

[0400] 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.

[0401] 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.

[0402] The detection circuit DC supplies input information based on the detection signal.

[0403] 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.

[0404] 《Example of configuration for area 231 3》 Region 231 is positioned closer to the pointer than the detection region 241, and region 231 is flexible (see Figures 21A and 21B). Furthermore, for example, an image showing the keyboard layout can be displayed in region 231 (see Figure 21A).

[0405] 《Example of detector configuration 2》 The detector 802(g,h) has a function to detect the amount of indentation, and the detector 802(g,h) detects the pointer via region 231 (see Figure 21B).

[0406] For example, the detector 802(g,h) detects the amount by which the pointer is pressed toward the detector 802(g,h). Specifically, the detector 802(g,h) detects the amount by which a finger or stylus pen is pressed toward the plane containing the detection region 241 from the plane containing region 231 (see Figure 21C).

[0407] For example, a pressure sensor can be used in detector 802(g,h). Specifically, an element whose electrical resistance changes according to pressure can be used in detector 802(g,h) (see Figure 21D). This allows detector 802(g,h) to detect the amount of indentation.

[0408] <Example of Input / Output Device Configuration 2> Furthermore, the input / output device described in this embodiment has a member 249 (see Figures 21A and 22A to 22C).

[0409] 《Example of the configuration of component 249》 Component 249 overlaps with the detection area 241 and is elastic.

[0410] For example, an elastic material can be used for member 249. Specifically, a spring, leaf spring, rubber, or sponge can be used.

[0411] This allows the detector 802(g,h) to detect the amount of pressure applied. Alternatively, the user can feel the force corresponding to the amount of pressure applied to the pointer.

[0412] Furthermore, for example, a structure that buckles upon jumping can be used for member 249. Specifically, a dome-shaped structure or the like can be used for member 249 (see Figure 22B).

[0413] Member 249 has a mode 1 that is stable in the region of small strain ε and a mode 2 that is stable in the region of large strain ε (see Figures 22C and 22D). Furthermore, at the buckling point, member 249 jumps from mode 1 to mode 2 (see Figure 22D). Also, by removing the strain, it reversibly jumps from mode 2 to mode 1.

[0414] As a result, the sensor 802(g,h) can detect a force σ corresponding to the amount of indentation up to the buckling point. Alternatively, the user can perceive this as a tactile sensation. Alternatively, the user can perceive a click sensation when exceeding the buckling point. Alternatively, a so-called tactile switch can be provided. Alternatively, by releasing the pointer that the user has pressed, the jump-and-buckle structure can return to its original mode.

[0415] Furthermore, by providing a detection area 241 superimposed on the jump-and-buckle structure, and a region 231 superimposed on the detection area 241, an image for operation can be displayed at a position overlapping with the jump-and-buckle structure. For example, a layout preferably used for a keyboard can be used for the layout of the jump-and-buckle structure. Alternatively, a layout preferably used for a home button can be used for the layout of the jump-and-buckle structure.

[0416] This allows the user to press down on the image used for the displayed operation, or to experience a click sensation when pressing down.

[0417] Alternatively, a member 249 can be used that has an area where multiple jump-and-buckle structures are provided across its entire surface. A detection area 241 can be provided superimposed on this area, and an area 231 can be provided superimposed on the detection area 241, allowing an image for operation to be displayed at a position overlapping with the area where the structures are provided across its entire surface.

[0418] This allows for the free placement of images used for operations that provide a click sensation when pressed.

[0419] Furthermore, the detection unit 250 may be arranged on top of the input / output device described in this embodiment. For example, a pressure-sensitive switch can be used as the detection unit 250. Specifically, a conductive material can be used in a dome-shaped structure that buckles as it jumps, and this dome-shaped structure can be used as the contact of the pressure-sensitive switch. This allows for the provision of a so-called membrane switch. Alternatively, a switch with a click sensation can be provided. Alternatively, a so-called tactile switch can be provided.

[0420] This embodiment can be appropriately combined with other embodiments shown in this specification.

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 23B and 23C).

[0428] 《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.

[0429] 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.

[0430] The transmission line 214 is electrically connected to the arithmetic unit 211, the storage unit 212, and the input / output interface 215.

[0431] 《Calculation section 211》 The arithmetic unit 211 includes, for example, a function for executing a program.

[0432] 《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.

[0433] Specifically, hard disks, flash memory, or memory using transistors containing oxide semiconductors can be used.

[0434] 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.

[0435] 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.

[0436] 《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 23A).

[0437] 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.

[0438] 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.

[0439] 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 7 can be used for the input / output device 220. The input / output device 220 may also include a communication unit 290.

[0440] [Example of the configuration of the display unit 230] The display unit 230 displays image information VI based on control information CI. For example, the display device described in Embodiment 6 can be used as the display unit 230.

[0441] [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.

[0442] For example, a human interface can be used in the input unit 240 (see Figure 23A). Specifically, a keyboard, mouse, touch sensor, microphone, or camera can be used in the input unit 240.

[0443] 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.

[0444] 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).

[0445] 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.

[0446] 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.

[0447] 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 23C). 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.

[0448] [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.

[0449] 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.

[0450] 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.

[0451] 《Communications Section 290》 The communications unit 290 has the function of supplying information to the network and acquiring information from the network.

[0452] 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.

[0453] This allows for the generation of control information CI based on input information II or detection information DS. Alternatively, image information VI can be displayed based on input information II or detection information DS. Alternatively, the information processing device can operate by understanding 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.

[0454] These components cannot be clearly separated, and one component may serve as a part of another, or may include parts of other components. For example, a touch panel with a touch sensor superimposed on a display panel is both a display unit and an input unit.

[0455] 《Example Configuration of the Calculation Unit 210 2》 The computing unit 210 includes an artificial intelligence unit 213 (see Figure 23A).

[0456] The artificial intelligence unit 213 is supplied with input information II or detection information DS, and based on the input information II or detection information DS, the artificial intelligence unit 213 infers control information CI. The artificial intelligence unit 213 also supplies the control information CI.

[0457] 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.

[0458] [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.

[0459] 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.

[0460] [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.

[0461] 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.

[0462] [Inference using detection information DS] Specifically, the artificial intelligence unit 213 can generate inference RI using the detection information DS. Alternatively, based on the inference RI, it can generate control information CI so that the user of the information processing device 200 feels comfortable.

[0463] 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.

[0464] 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.

[0465] <Example of Information Processing Device Configuration 2> Another configuration of an information processing device according to one embodiment of the present invention will be described with reference to Figures 24A and 24B.

[0466] "program" A program according to one aspect of the present invention has the following steps (see Figure 24A).

[0467] [Step 1] In the first step, the settings are initialized (see Figure 24A(S1)).

[0468] 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.

[0469] [Step 2] In the second step, interrupt handling is enabled (see Figure 24A(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.

[0470] 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.

[0471] [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 24A(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.

[0472] 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.

[0473] 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.

[0474] 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.

[0475] 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.

[0476] 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.

[0477] 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.

[0478] 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.

[0479] Incidentally, for example, when using a light-emitting element as a display element, the light-emitting element can be made to emit light in pulses to display image information. Specifically, an organic EL element can be made to emit light in pulses, 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. In addition, by setting the duty cycle to 20% or less, the afterimage included in the display can be reduced.

[0480] [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 24A(S4)).

[0481] For example, the termination instruction supplied during interrupt handling may be used for the decision.

[0482] [Step 5] In the fifth step, the process ends (see Figure 24A(S5)).

[0483] Interrupt handling Interrupt handling comprises the following steps 6 through 8 (see Figure 24B).

[0484] [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 24B(S6)). Alternatively, the color temperature or chromaticity of the ambient light may be detected instead of the illuminance of the environment.

[0485] [Step 7] In the seventh step, the display method is determined based on the detected illuminance information (see Figure 24B(S7)). For example, the brightness of the display is determined to be neither too dim nor too bright.

[0486] Furthermore, if the color temperature or chromaticity of the ambient light is detected in step 6, the displayed color may be adjusted.

[0487] [Step 8] In the eighth step, the interrupt processing is terminated (see Figure 24B(S8)).

[0488] <Example 3 of Information Processing Device Configuration> Another configuration of an information processing device according to one embodiment of the present invention will be described with reference to Figure 25.

[0489] Figure 25A is a flowchart illustrating a program according to one embodiment of the present invention. Figure 25A is a flowchart illustrating an interrupt process different from the interrupt process shown in Figure 24B.

[0490] Note that configuration example 3 of the information processing device differs from the interrupt processing described with reference to Figure 24B 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.

[0491] Interrupt handling Interrupt processing comprises the following steps 6 through 8 (see Figure 25A).

[0492] [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 25A(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.

[0493] [Step 7] In the seventh step, change the mode (see Figure 25A(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.

[0494] 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 25B).

[0495] 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 25B and 25C). 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.

[0496] 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.

[0497] 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.

[0498] [Step 8] In the eighth step, the interrupt handling is terminated (see Figure 25A(U8)). Note that the interrupt handling may be repeatedly executed during the period in which the main processing is running.

[0499] 《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.

[0500] 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.

[0501] 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.

[0502] 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.

[0503] 《Instructions to associate with a specified event》 For example, a termination command can be associated with a predetermined event.

[0504] 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.

[0505] 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.

[0506] 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.

[0507] For example, commands to acquire information delivered using a push-type service, using the communication unit 290, can be associated with a predetermined event.

[0508] 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 23C). Alternatively, it can receive materials distributed in a conference room at a company, etc., and use them as meeting materials.

[0509] <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 26.

[0510] Note that Configuration Example 4 of the information processing device, which will be explained with reference to Figure 26A, differs from the Configuration Example explained with reference to Figure 24B 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.

[0511] Interrupt handling The interrupt handling process comprises steps 6 through 11 (see Figure 26A).

[0512] [Step 6] In step 6, if the predetermined event is supplied, proceed to step 7; otherwise, proceed to step 11 (see Figure 26A(V6)).

[0513] 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 such as a finger or the proximity of an object.

[0514] [Step 7] In the seventh step, the first region SH is identified (see Figure 26A(V7)).

[0515] 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.

[0516] Specifically, a finger THM or the like that is in contact with or close to a functional panel 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 26B).

[0517] 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 pixel 703(i,j) of a functional panel according to one embodiment of the present invention, and the image can be processed to identify a first region SH.

[0518] Alternatively, using the pixel 703(i,j) of a functional panel 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 the pixel 703(i,j), and the first region SH can be identified by image processing.

[0519] 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.

[0520] [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 26A(V8) and 26B). 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.

[0521] [Step 9] In the ninth step, the image FI is displayed so that the second region overlaps the first region SH (see Figures 26A(V9) and 26B).

[0522] For example, an image signal can be generated from image FI and supplied to region 231, and light can 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 the brightness and display the image.

[0523] 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.

[0524] [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 26A(V10) and 26B).

[0525] 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 26C).

[0526] 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.

[0527] 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.

[0528] [Step 11] In the 11th step, the interrupt processing is terminated (see Figure 26A (V11)).

[0529] <Example of Information Processing Device Configuration 5> Another configuration of an information processing device according to one aspect of the present invention will be described with reference to Figure 27.

[0530] Interrupt handling The interrupt handling process comprises steps 6 through 9 (see Figure 27A).

[0531] [Step 6] In step 6, if the predetermined event is supplied, proceed to step 7; otherwise, proceed to step 9 (see Figure 27A(W6)).

[0532] For example, the subject 30 can be placed in a predetermined location on the information processing device 200, and a predetermined event can be supplied using the input unit 240 (see Figure 27B). Specifically, contact or proximity of a finger or the like can be detected using the touch sensor in area 231(1) and used for a predetermined event. For example, a touch sensor can be placed superimposed on the location where an image associated with interrupt processing is displayed. Specifically, an image associated with interrupt processing can be displayed in area 231(1), and the input unit 240 placed superimposed on area 231(1) can be used.

[0533] [Step 7] In the seventh step, imaging is performed using region 231(1) (see Figure 27A(W7)).

[0534] For example, a still image is captured when the subject 30 approaches or is in close contact with region 231 (see Figure 27C). Specifically, a still image is captured when the intensity of ambient light incident on region 231 falls below a predetermined value. Alternatively, a still image is captured when no change exceeding a predetermined size is observed in the image captured by region 231 for a predetermined period of time. Or, a still image is captured after the housing of the information processing device 200 is closed.

[0535] [Step 8] In the eighth step, the region 231(1) is used for display (see Figure 27A(W8)).

[0536] For example, the still image captured in step 7 is displayed in region 231 (see Figure 27D).

[0537] [Step 9] In the ninth step, the interrupt processing is terminated (see Figure 27A(W9)).

[0538] This allows for imaging of subjects such as fingers that are in contact or in close proximity, while illuminating them. Alternatively, it enables the acquisition of clear images with suppressed distortion. Furthermore, it allows for the reproduction of information published in printed materials, etc., into electronic data. As a result, it is possible to provide a novel information processing device with superior convenience, usefulness, and reliability.

[0539] (Embodiment 9) 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 28A to 30B.

[0540] Figure 28A is a block diagram of the information processing device, and Figures 28B to 28E are perspective views illustrating the configuration of the information processing device. Figures 29A to 29E are also perspective views illustrating the configuration of the information processing device. Furthermore, Figures 30A and 30B are perspective views illustrating the configuration of the information processing device.

[0541] <Information Processing Device> The information processing device 5200B described in this embodiment includes an arithmetic unit 5210 and an input / output device 5220 (see Figure 28A).

[0542] The arithmetic unit 5210 has a function to be supplied with operation information and a function to supply image information based on the operation information.

[0543] The input / output device 5220 includes a display unit 5230, an input unit 5240, a detection unit 5250, a communication unit 5290, a function for supplying operation information, and a function for supplying image information. Furthermore, the input / output device 5220 includes a function for supplying detection information, a function for supplying communication information, and a function for receiving communication information.

[0544] The input unit 5240 has a function to supply operation information. For example, the input unit 5240 supplies operation information based on the user's operation of the information processing device 5200B.

[0545] Specifically, the input unit 5240 can use a keyboard, hardware buttons, pointing device, touch sensor, illuminance sensor, imaging device, voice input device, eye-tracking device, posture detection device, etc.

[0546] The display unit 5230 includes a display panel and a function for displaying image information. For example, the display panel described in Embodiments 1 to 5 can be used in the display unit 5230.

[0547] The detection unit 5250 has a function to supply detection information. For example, it has a function to detect the surrounding environment in which the information processing device is being used and supply it as detection information.

[0548] Specifically, illuminance sensors, imaging devices, posture detection devices, pressure sensors, and human presence sensors can be used in the detection unit 5250.

[0549] The communication unit 5290 has functions for receiving and supplying communication information. For example, it has functions for connecting with other electronic devices or communication networks via wireless or wired communication. Specifically, it has functions such as wireless local area communication, telephone communication, and short-range wireless communication.

[0562] This embodiment can be appropriately combined with other embodiments shown in this specification.

[0563] 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.

[0564] Here, X and Y are assumed to be objects (for example, devices, elements, circuits, wiring, electrodes, terminals, conductive films, layers, etc.).

[0565] 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.).

[0566] 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.

[0567] 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.

[0568] 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.

[0569] 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.

[0570] 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.

[0571] 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.

[0572] 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.).

[0573] 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]
