[0014] The first element has a function of emitting light, and the first element includes a first electrode, a second electrode, and a layer including a light-emitting material. The layer including the light-emitting material includes a region sandwiched between the first electrode and the second electrode, and the layer including the light-emitting material includes gallium nitride.

[0017] The first driving circuit includes a first transistor, the first transistor being electrically connected to the first electrode through the first opening and the third opening, and the second driving circuit includes a second transistor, the second transistor being electrically connected to the second electrode through the second opening and the fourth opening.

[0018] This allows the first pixel to be driven using the first drive circuit and the second drive circuit. Alternatively, the first element can be passively driven without providing a pixel circuit in the first pixel. Alternatively, the influence of the operation of the first element on the operation of the second element can be suppressed. Alternatively, the second element can be arranged close to the first element. Alternatively, the ratio of the area of ​​the first element to the area of ​​the first pixel and the ratio of the area of ​​the second element to the area of ​​the second pixel can be increased.

[0030] This makes it possible to supply image information to a plurality of pixels, thereby providing a novel functional panel that is highly convenient, useful, and reliable.

[0031] (7) Another aspect of the present invention is a display device having a control unit and the above-described functional panel.

[0036] The input section has a sensing area, the input section detects an object proximate to the sensing area, and the sensing area has an area overlapping the set of pixels.

[0037] This makes it possible to detect an object that is close to an area overlapping with the display unit while displaying image information using the display unit. Alternatively, position information can be input using a finger or the like that is brought close to the display unit as a pointer. Alternatively, position information can be associated with image information displayed on the display unit. As a result, it is possible to provide a novel input / output device that is highly convenient, useful, and reliable.

[0044] This allows the arithmetic unit to generate image information or control information based on information supplied using various input devices, thereby providing a novel information processing device that is highly convenient, useful, and reliable.

[0045] In the drawings accompanying this specification, components are classified by function and shown in block diagrams as independent blocks; however, in actuality, it is difficult to completely separate components by function, and one component may be involved in multiple functions.

[0046] In this specification, the names of the source and drain of a transistor are interchanged depending on the polarity of the transistor and the level of the potential applied to each terminal. In general, in an n-channel transistor, a terminal to which a low potential is applied is called a source, and a terminal to which a high potential is applied is called a drain. In addition, in a p-channel transistor, a terminal to which a low potential is applied is called a drain, and a terminal to which a high potential is applied is called a source. In this specification, for convenience, the connection relationship of a transistor may be described assuming that the source and drain are fixed, but in reality, the names of the source and drain are interchanged according to the above-mentioned potential relationship.

[0047] In this specification, the source of a transistor means a source region that is a part of a semiconductor film that functions as an active layer, or a source electrode connected to the semiconductor film. Similarly, the drain of a transistor means a drain region that is a part of the semiconductor film, or a drain electrode connected to the semiconductor film. Furthermore, the gate means a gate electrode.

[0048] In this specification, a state in which transistors are connected in series means, for example, a state in which only one of the source or drain of a first transistor is connected to only one of the source or drain of a second transistor, and a state in which transistors are connected in parallel means a state in which one of the source or drain of a first transistor is connected to one of the source or drain of a second transistor, and the other of the source or drain of the first transistor is connected to the other of the source or drain of the second transistor.

[0049] In this specification, the term "connection" refers to an electrical connection, and corresponds to a state in which a current, voltage, or potential can be supplied or transmitted. Therefore, the state of being connected does not necessarily refer to a state of being directly connected, but also includes a state of being indirectly connected via a circuit element such as a wiring, resistor, diode, or transistor so that a current, voltage, or potential can be supplied or transmitted.

[0050] In this specification, even if components that are independent on a circuit diagram are connected to each other, in reality, one conductive film may have the functions of multiple components, for example, when part of a wiring functions as an electrode. In this specification, the term "connection" also includes such cases in which one conductive film has the functions of multiple components.

[0051] In this specification, one of a first electrode and a second electrode of a transistor refers to a source electrode, and the other refers to a drain electrode. Effect of the Invention

Note that effects other than these will become apparent from the description in the specification, drawings, claims, etc., and it is possible to extract effects other than these from the description in the specification, drawings, claims, etc. [Brief description of the drawings]

[0057] The embodiments will be described in detail with reference to the drawings.

Fig. 5(C) is a cross-sectional view illustrating a part of Fig. 5(A).

[0064] In this specification, variables whose values ​​are integers of 1 or more may be used in codes. For example, (p) including a variable p whose value is an integer of 1 or more may be used as part of a code that specifies any one of up to p components. Also, for example, (m, n) including variables m and n whose values ​​are integers of 1 or more may be used as part of a code that specifies any one of up to m×n components.

[0065] <Example of the configuration of the function panel 700> Functional panel 700 described in this embodiment has a set of pixels 703(i,j) (see Figures 1(A), 1(B), and 2(A)). Functional panel 700 also has functional layers 520 and 120 (see Figure 3). Functional panel 700 also has a set of pixels 703(i+1,j).

[0066] Example of the configuration of a pair of pixels 703(i,j) A set of pixels 703(i,j) includes pixel 702G(i,j), pixel 702B(i,j) and pixel 702R(i,j) (see FIG. 2A). Additionally, a set of pixels 703(i+1,j) includes element 550G(i+1,j).

[0067] The pixel 702G(i,j) includes an element 550G(i,j), and the pixel 702B(i,j) includes an element 550B(i,j). The pixel 702R(i,j) includes an element 550R(i,j). For example, the pixel 702G(i,j) has a function of displaying green, the pixel 702B(i,j) has a function of displaying blue, and the pixel 702R(i,j) has a function of displaying red. Note that a pixel circuit may be provided in the pixel 702G(i,j) to actively drive the element 550G(i,j). For example, a transistor may be formed in the functional layer 520 and used in the pixel circuit. Alternatively, the transistor may be electrically connected to the element 550G(i,j).

[0068] Example of configuration of functional layer 520 The functional layer 520 includes an insulating film 521 and an insulating film 573 (see FIGS. 3 and 4A).

[0069] Insulating film 521 has a region where element 550G(i,j) is sandwiched between itself and insulating film 573, and insulating film 521 has a region where element 550B(i,j) is sandwiched between itself and insulating film 573. In addition, insulating film 521 has opening 591X(i) and opening 591Y2(j) (see FIGS. 5(A) and 5(B)).

[0070] The insulating film 573 has a function of isolating the element 550B(i,j) from the element 550G(i,j) (see FIG. 4A).

[0071] 《Example of the configuration of element 550G(i,j)》 Element 550G(i,j) has a function of emitting light, and includes electrode 551(i), electrode 552(j), and layer 553 including a light-emitting material.

[0072] Layer 553 including a light emitting material comprises a region sandwiched between electrode 551(i) and electrode 552(j), and layer 553 including a light emitting material includes gallium nitride.

[0073] For example, a mini LED can be used for element 550G(i,j). Specifically, the area of ​​the light emitting region can be 1 mm 2 Less than 50,000 μm, preferably 2 Less than or equal to 30,000 μm, more preferably 30,000 μm 2 Less than 10000 μm, more preferably 10000 μm 2 Below, 200μm 2 The above mini LEDs can be used for element 550G(i,j).

[0074] Alternatively, a micro LED can be used for the element 550G(i,j). Specifically, the area of ​​the light emitting region is 200 μm 2 Less than 60 μm, preferably 2 Less than or equal to 15 μm, more preferably 2 Less than 5 μm, more preferably 2 Below, 3μm 2 The above micro LED can be used for element 550G(i,j).

[0075] [Configuration example 1 of the layer 553 containing a light-emitting material] The element 550G(i,j) includes, for example, a P-type cladding layer 553P, an N-type cladding layer 553N, and a light-emitting layer 553EM. The light-emitting layer 553EM includes a region sandwiched between the P-type cladding layer 553P and the N-type cladding layer 553N. This allows carriers to recombine in the light-emitting layer 553EM. As a result, light emission due to the recombination of carriers can be obtained.

[0076] For example, a laminate material laminated so as to emit blue light, a laminate material laminated so as to emit green light, or a laminate material laminated so as to emit red light can be used for the pixel. Specifically, a gallium phosphide compound, a gallium arsenide compound, a gallium aluminum arsenide compound, an aluminum gallium indium phosphide compound, an indium gallium nitride compound, etc. can be used for the pixel.

[0077] In particular, an element that emits blue light can be used for element 550G(i,j) and element 550B(i,j), which allows element 550G(i,j) and element 550B(i,j) to be formed in the same process.

[0078] Also, an element that emits ultraviolet light can be used for element 550G(i,j) and element 550B(i,j). Note that a color conversion layer can be disposed so as to overlap element 550B(i,j) to convert the ultraviolet light into blue light.

[0079] Example of the configuration of the functional layer 120 The functional layer 120 includes an insulating film 118, a driving circuit DX, and a driving circuit DY (see FIG. 3). The functional layer 120 also includes an insulating film .

[0080] The insulating film 118 is in contact with the insulating film 521, and the insulating film 118 has an opening 191X(i) and an opening 191Y2(j) (see FIGS. 4(A), 5(A), and 5(B)).

[0081] The driving circuit DX includes a transistor MDX(i), which is electrically connected to the electrode 551(i) via the opening 591X(i) and the opening 191X(i) (see FIG. 5(A)). The driving circuit DX has a function of selecting one of a plurality of electrodes and supplying a predetermined voltage to it. For example, the driving circuit DX selects the electrode 551(i) and supplies a voltage higher than that to the electrode 552(j).

[0082] For example, contact 119X(i) is electrically connected to contact 519X(i), which is electrically connected to electrode 551(i). In addition, contact 119Y2(j) is electrically connected to contact 519Y2(j), which is electrically connected to electrode 552(j) via N-type cladding layer 553N.

[0083] For example, a metal may be used for contacts 119X(i), 519X(i), 119Y2(j), and 519Y2(j). Specifically, copper or gold may be used.

[0084] The driving circuit DY includes a transistor MDY(j), which is electrically connected to the electrode 552(j) via the opening 591Y2(i) and the opening 191Y2(j) (see FIG. 5(B)). The driving circuit DY has a function of selecting one of the multiple electrodes and supplying a predetermined voltage to it. For example, the driving circuit DY selects the electrode 552(j) and supplies a voltage lower than that to the electrode 551(i).

[0085] This allows the pixel 702G(i,j) to be driven using the drive circuit DX and the drive circuit DY. Alternatively, the element 550G(i,j) can be passively driven without providing a pixel circuit in the pixel 702G(i,j). Alternatively, the influence of the operation of the element 550G(i,j) on the operation of the element 550B(i,j) can be suppressed. Alternatively, the element 550B(i,j) can be arranged closer to the element 550G(i,j). Alternatively, the ratio of the area of ​​the element 550G(i,j) to the area of ​​the pixel 702G(i,j) can be increased. Alternatively, the ratio of the area of ​​the element 550B(i,j) to the area of ​​the pixel 702B(i,j) can be increased. As a result, a novel functional panel with excellent convenience, usefulness, or reliability can be provided.

[0086] <Example of insulating film configuration> The insulating film 521 includes an insulating film 521A and an insulating film 521B, and the insulating film 521A contains silicon and oxygen (see FIGS. 5A and 5B).

[0087] The insulating film 118 includes an insulating film 118A and an insulating film 118B. Moreover, the insulating film 116 includes an insulating film 116A and an insulating film 116B.

[0088] The insulating film 118B contains silicon and oxygen, and has a region that bonds with the insulating film 521A. This allows the insulating film 118B and the insulating film 521A to be bonded together, for example, by using a surface activated bonding method. Alternatively, the functional layer 520 and the functional layer 120 can be bonded together.

[0089] The insulating film 118A contains silicon and nitrogen, and has a region sandwiched between the insulating film 118B and the transistor MDX(i) (see FIG. 5(A)).

[0090] <<Example of transistor configuration>> The transistor MDX(i) includes single crystal silicon. In addition, in the process of forming the transistor MDX(i), the transistor MDY(j) and the transistor MD can be formed (see FIGS. 4(B) and 5(B)). For example, a single crystal silicon substrate can be used as the base material 110S to form a transistor on the base material 110S. This allows the transistor MD to be used in a drive circuit or the like (see FIG. 4(A)).

[0091] The transistor MDX(i) includes a semiconductor film 108, a conductive film 104, a conductive film 112A, and a conductive film 112B (see FIG. 5C).

[0092] The semiconductor film 108 includes a region 108A electrically connected to the conductive film 112A and a region 108B electrically connected to the conductive film 112B. The semiconductor film 108 includes a region 108C between the region 108A and the region 108B.

[0093] The conductive film 104 has a region overlapping with the region 108C, and has a function of a gate electrode.

[0094] The insulating film 106 has a region sandwiched between the semiconductor film 108 and the conductive film 104. The insulating film 106 functions as a gate insulating film.

[0095] The conductive film 112A has either a function of a source electrode or a function of a drain electrode, and the conductive film 112B has the other function of a source electrode or a function of a drain electrode.

[0096] This makes it possible to suppress the diffusion of impurities that cause operational problems into the transistor MDX(i). Alternatively, for example, the driver circuit DX can be arranged so as to overlap the pixel 702G(i,j). Alternatively, the external dimensions of the functional panel can be reduced. As a result, it is possible to provide a novel functional panel that is highly convenient, useful, and reliable.

[0097] Configuration Example 1 of Semiconductor Film 108 For example, a semiconductor containing a Group 14 element can be used for the semiconductor film 108. Specifically, a semiconductor containing silicon can be used for the semiconductor film 108.

[0098] [Hydrogenated amorphous silicon] For example, hydrogenated amorphous silicon can be used for the semiconductor film 108. Alternatively, microcrystalline silicon or the like can be used for the semiconductor film 108. 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 108. Alternatively, it is easy to increase the size of the functional panel.

[0099] [Polysilicon] For example, polysilicon can be used for the semiconductor film 108. This allows the field effect mobility of the transistor to be higher than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 108. Alternatively, for example, the driving capability can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 108. Alternatively, for example, the aperture ratio of a pixel can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 108.

[0100] Alternatively, for example, the reliability of the transistor can be improved as compared to a transistor in which hydrogenated amorphous silicon is used for the semiconductor film 108 .

[0101] Alternatively, the temperature required to manufacture the transistor can be made lower than that of a transistor using single crystal silicon, for example.

[0102] Alternatively, a semiconductor film used for a transistor in a driver circuit can be formed in the same process as a semiconductor film used for a transistor in a pixel circuit. Alternatively, the driver circuit can be formed over the same substrate as the substrate on which the pixel circuit is formed. Alternatively, the number of components included in an electronic device can be reduced.

[0103] [Single crystal silicon] For example, single crystal silicon can be used for the semiconductor film 108. This allows for higher definition than, for example, a functional panel using hydrogenated amorphous silicon for the semiconductor film 108. Alternatively, for example, a functional panel with less display unevenness than, for example, a functional panel using polysilicon for the semiconductor film 108 can be provided. Alternatively, for example, smart glasses or a head mounted display can be provided.

[0104] Configuration Example 2 of Semiconductor Film 108 For example, metal oxide can be used for the semiconductor film 108. This allows the pixel circuit to hold an image signal for a longer period of time compared to a pixel circuit that uses a transistor with amorphous silicon used for 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 a user of the information processing device can be reduced. Also, power consumption associated with driving can be reduced.

[0105] For example, a transistor including an oxide semiconductor can be used. Specifically, an oxide semiconductor including indium, an oxide semiconductor including indium, gallium, and zinc, or an oxide semiconductor including indium, gallium, zinc, and tin can be used for a semiconductor film.

[0106] For example, a transistor having a smaller leakage current in an off state than a transistor using amorphous silicon for a semiconductor film can be used. Specifically, a transistor using an oxide semiconductor for a semiconductor film can be used as a switch or the like. This allows the potential of a floating node to be held for a longer time than a circuit using a transistor using amorphous silicon for a switch.

[0107] This makes it possible to suppress display flickering. Or, it makes it possible to reduce power consumption. Or, it makes it possible to display fast-moving videos smoothly. Or, it makes it possible to display photographs and the like with a rich range of gradations. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0108] Configuration Example 3 of Semiconductor Film 108 For example, a compound semiconductor can be used as the semiconductor of a transistor, specifically, a semiconductor containing gallium arsenide can be used.

[0109] For example, an organic semiconductor can be used as a semiconductor for a transistor. Specifically, an organic semiconductor containing polyacenes or graphene can be used as a semiconductor film.

[0110] Example of pixel configuration The pixel 702G(i,j) has a color conversion layer CC(G) (see FIG. 4(A)).

[0111] The color conversion layer CC(G) has a function of converting the color of the light emitted by the element 550G(i,j) into a different color.

[0112] Pixel 702B(i,j) displays the color of light emitted by element 550B(i,j), which emits the same color light as that emitted by element 550G(i,j).

[0113] Color conversion layer Color conversion layer CC(G) has a region sandwiched between substrate 770 and element 550G(i,j).

[0114] For example, a material that emits light having a wavelength longer than the wavelength of the incident light can be used for the color conversion layer. For example, a material that absorbs blue light or ultraviolet light and converts it to green light and emits it, a material that absorbs blue light or ultraviolet light and converts it to red light and emits it, or a material that absorbs ultraviolet light and converts it to blue light and emits it can be used for the color conversion layer. For example, a phosphor can be used for the color conversion layer. Specifically, quantum dots with a diameter of several nm can be used for the color conversion layer. This allows light to be emitted with a spectrum with a narrow half-width. Or, light with high saturation can be emitted.

[0115] For example, pixel 702G(i,j) includes a color conversion layer CC(G) and an element 550G(i,j), which emits blue light and converts the blue light to green light (see FIG. 2B). Pixel 702R(i,j) includes a color conversion layer CC(R) and an element 550R(i,j), which emits blue light and converts the blue light to red light. Pixel 702B(i,j) includes an element 550B(i,j), which emits blue light.

[0116] This allows the elements 550G(i,j), 550R(i,j), and 550B(i,j) to be formed in the same process. Also, a set of pixels 703(i,j) can be used to display a variety of colors.

[0117] This allows element 550B(i,j) to be formed in the same process as element 550G(i,j). Alternatively, pixel 702G(i,j) can be used to display a color different from that of pixel 702B(i,j). As a result, a novel functional panel with excellent convenience, usability, and reliability can be provided.

[0118] <Example of the configuration of the function panel 700> The functional panel 700 includes a base material 110S, a base material 770, and a sealing material 705 (see FIG. 4(A)). The functional panel 700 also includes a structure KB.

[0119] 《Structure KB》 The structural body KB has a region sandwiched between the functional layer 520 and the base material 770 (see FIG. 5(A)). The structural body KB also has a function of providing a predetermined gap between the functional layer 520 and the base material 770.

[0120] 《Functional membrane 770P, etc.》 The functional film 770P has a region that overlaps with the element 550G(i,j) (see FIG. 4(A)).

[0121] For example, an anti-reflection film, a polarizing film, a retardation film, a light diffusing film, a light collecting film, or the like can be used for the functional film 770P.

[0122] For example, an anti-reflection film having a thickness of 1 μm or less can be used for the functional film 770P. Specifically, a laminated film having three or more dielectric layers, preferably five or more dielectric layers, more preferably fifteen or more dielectric layers can be used for the functional film 770P. This makes it possible to suppress the reflectance to 0.5% or less, preferably 0.08% or less.

[0123] For example, a circularly polarizing film can be used for the functional film 770P.

[0124] In addition, the functional film 770P can be used with antistatic films that prevent dust from sticking, water-repellent films that make it difficult for dirt to adhere, oil-repellent films that make it difficult for dirt to adhere, anti-reflection films, non-glossy films (anti-glare films), hard coat films that prevent scratches from occurring during use, and self-repairing films that repair any scratches that do occur.

[0125] For example, the terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material (see FIG. 3). Specifically, the terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material CP.

[0126] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0127] (Embodiment 2) In this embodiment, a structure of a functional panel according to one embodiment of the present invention will be described with reference to FIGS.

[0128] FIG. 6 is a block diagram illustrating the configuration of a functional panel according to an embodiment of the present invention.

[0129] <Example of the configuration of the function panel 700> The functional panel 700 described in this embodiment has an area 231 (see FIG. 6).

[0130] <<Configuration Example 1 of Area 231>> The region 231 includes a group of pixels 703(i,1) to 703(i,n), another group of pixels 703(1,j) to 703(m,j), a conductive film X(i) and a conductive film Y2(j). A film in which an electrode 551(i) and a P-type clad layer 553P are stacked can be used for the conductive film X(i) (see FIG. 5(A)). A film in which an electrode 552(j) and an N-type clad layer 553N are stacked can be used for the conductive film Y2(j) (see FIG. 5(B)). The region 231 also includes a conductive film X(i+1) and a conductive film Y1(j) (see FIG. 2(A)).

[0131] A group of pixels 703(i,1) to 703(i,n) are arranged in the row direction (the direction indicated by the arrow R1 in the drawing), and the group of pixels 703(i,1) to 703(i,n) includes a pixel 703(i,j). The group of pixels is electrically connected to a conductive film X(i).

[0132] Another group of a set of pixels 703(1,j) to a set of pixels 703(m,j) are arranged in a column direction (the direction indicated by the arrow C1 in the figure) intersecting the row direction, and the other group of a set of pixels 703(1,j) to a set of pixels 703(m,j) includes a set of pixels 703(i,j). The other group of a set of pixels 703(1,j) to a set of pixels 703(m,j) are electrically connected to a conductive film Y2(j).

[0133] This makes it possible to supply image information to a plurality of pixels, thereby providing a novel functional panel that is highly convenient, useful, and reliable.

[0134] <<Configuration Example 2 of Area 231>> Region 231 has a plurality of sets of pixels, for example, 600 or more per inch. The plurality of sets of pixels includes set of pixels 703(i,j). Preferably, region 231 has a plurality of sets of pixels, for example, 1000 or more per inch, more preferably 3000 or more per inch, and even more preferably 6000 or more per inch. This can reduce, for example, the screen door effect.

[0135] <<Configuration Example 3 of Area 231>> The region 231 includes a plurality of pixels arranged in a matrix. For example, the region 231 includes 7600 or more pixels in the row direction, and the region 231 includes 4300 or more pixels in the column direction. Specifically, the region 231 includes 7680 pixels in the row direction, and 4320 pixels in the column direction.

[0136] This makes it possible to display a high-definition image, thereby providing a novel functional panel that is highly convenient and reliable.

[0137] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0138] (Embodiment 3) In this embodiment, a structure of a display device according to one embodiment of the present invention will be described with reference to FIG.

[0139] FIG. 7A is a block diagram of a display device of one embodiment of the present invention, and FIGS. 7B to 7D are perspective views illustrating the appearance of the display device of one embodiment of the present invention.

[0140] <Example of display device configuration> The display device described in this embodiment includes a control unit 238 and a functional panel 700 (see FIG. 7(A)).

[0141] Configuration example 1 of the control unit 238 The control unit 238 is supplied with image information VI and control information CI, which may be, for example, a clock signal or a timing signal.

[0142] The control unit 238 generates information based on the image information VI, and generates a control signal based on the control information CI, and also provides the information and the control signal.

[0143] For example, the information includes a gradation of 8 bits or more, preferably 12 bits or more. Also, for example, a clock signal or a start pulse of a shift register used in a driving circuit can be used as a control signal.

[0144] <<Configuration Example 2 of the Control Unit 238>> For example, the decompression circuit 234 and the image processing circuit 235 can be used in the control unit 238 .

[0145] 《Extension circuit 234》 The decompression circuit 234 has a function of decompressing the image information VI that is supplied in a compressed state. The decompression circuit 234 has a storage unit. The storage unit has a function of storing, for example, the decompressed image information.

[0146] "Image processing circuit 235" The image processing circuit 235 includes, for example, a storage area. The storage area has a function of storing information included in the image information VI, for example.

[0147] The image processing circuit 235 has, for example, a function of correcting the image information VI based on a predetermined characteristic curve to generate information, and a function of supplying the information.

[0148] <<Configuration example 1 of function panel 700>> The functional panel 700 is supplied with information and a control signal, and a set of pixels 703(i,j) displays based on the information. For example, the functional panel 700 described in the first or second embodiment can be used.

[0149] This allows the image information VI to be displayed using the functional panel 700. As a result, a novel display device with excellent convenience, usefulness, and reliability can be provided. Alternatively, for example, an information device terminal (see FIG. 7(B)), a video display system (see FIG. 7(C)), or a computer (see FIG. 7(D)) can be provided.

[0150] <<Configuration example 2 of function panel 700>> For example, the functional panel 700 includes a driving circuit and a control circuit.

[0151] <Drive circuit> The drive circuits operate based on control signals, and the operation of multiple drive circuits can be synchronized by using the control signals (see FIG. 7(A)).

[0152] For example, the drive circuit DX can be used in the functional panel 700. The drive circuit DX is supplied with a control signal and has a function of supplying a first selection signal.

[0153] Also, for example, the driving circuit DY can be used in the functional panel 700. The driving circuit DY is supplied with control signals and information and can supply image signals.

[0154] Control circuit The control circuit has a function of generating and supplying a control signal, which may be, for example, a clock signal or a timing signal.

[0155] For example, a control circuit can be provided in the functional layer 120. Specifically, a single crystal silicon substrate on which a driving circuit and a control circuit are formed can be used for the functional layer 120. This allows not only the driving circuit but also the control circuit to be arranged in layers in the region 231. Alternatively, the number of components can be reduced. Alternatively, the outer shape of the display device can be made smaller.

[0156] Alternatively, a control circuit formed on a rigid substrate can be used for the functional panel, or the control circuit formed on the rigid substrate can be electrically connected to the control unit 238 using a flexible printed circuit board.

[0157] For example, the timing controller 233 can be used for the control circuit.

[0158] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0159] (Embodiment 4) In this embodiment, a configuration of an input / output device of one embodiment of the present invention will be described with reference to FIG.

[0160] FIG. 8 is a block diagram illustrating a configuration of an input / output device of one embodiment of the present invention.

[0161] <Example of I / O device configuration> The input / output device described in this embodiment includes an input unit 240 and a display unit 230 (see FIG. 8).

[0162] Configuration example of display unit 230 The display unit 230 includes a functional panel 700. For example, the functional panel 700 described in the first or second embodiment can be used for the display unit 230. Note that a configuration having the input unit 240 and the display unit 230 can be referred to as a functional panel 700TP.

[0163] Configuration example 1 of the input unit 240 The input unit 240 has a detection area 241. The input unit 240 detects an object approaching the detection area 241.

[0164] Sensing region 241 comprises the area that overlaps a set of pixels 703(i,j).

[0165] This makes it possible to detect an object approaching an area overlapping with the display unit 230 while displaying image information using the display unit 230. Alternatively, position information can be input using a finger or the like brought close to the display unit 230 as a pointer. Alternatively, position information can be associated with image information displayed on the display unit 230. As a result, it is possible to provide a novel input / output device that is highly convenient, useful, and reliable.

[0166] Configuration example of detection area 241 The sensing area 241 may, for example, include one or more detectors.

[0167] The detection region 241 has a group of detectors 802(g,1) through 802(g,q) and another group of detectors 802(1,h) through 802(p,h), where g is an integer between 1 and p, h is an integer between 1 and q, and p and q are integers greater than or equal to 1.

[0168] A group of detectors 802(g,1) to 802(g,q) including a detector 802(g,h) are arranged in the row direction (the direction indicated by the arrow R2 in the figure) and are electrically connected to the wiring CL(g). Note that the direction indicated by the arrow R2 may be the same as the direction indicated by the arrow R1, or may be different.

[0169] In addition, another group of detectors 802(1,h) to 802(p,h), including detector 802(g,h), are arranged in a column direction (the direction indicated by arrow C2 in the figure) that intersects with the row direction, and are electrically connected to wiring ML(h).

[0170] Detector The detector has a function of detecting a nearby pointer. For example, a finger or a stylus pen can be used as the pointer. For example, a metal piece or a coil can be used as the stylus pen.

[0171] Specifically, a capacitance type proximity sensor, an electromagnetic induction type proximity sensor, an optical type proximity sensor, a resistive film type proximity sensor, or the like can be used as the detector.

[0172] Furthermore, detectors of multiple types can be used in combination. For example, a detector for detecting a finger and a detector for detecting a stylus pen can be used in combination.

[0173] This makes it possible to determine the type of pointer. Alternatively, different commands can be associated with the detection information based on the determined type of pointer. Specifically, if it is determined that a finger is used as the pointer, the detection information can be associated with a gesture. Alternatively, if it is determined that a stylus pen is used as the pointer, the detection information can be associated with a drawing process.

[0174] Specifically, a finger can be detected using a capacitance type, a pressure sensitive type, or an optical type proximity sensor, or a stylus pen can be detected using an electromagnetic induction type or an optical type proximity sensor.

[0175] Configuration example 2 of input unit 240 The input section 240 comprises an oscillator circuit OSC and a detection circuit DC (see FIG. 8).

[0176] The oscillator circuit OSC supplies a search signal to the detector 802(g,h). For example, a square wave, a sawtooth wave, a triangular wave, a sine wave, etc. can be used as the search signal.

[0177] The detector 802(g,h) generates and provides a detection signal that varies based on the distance to the pointer proximate to the detector 802(g,h) and the probe signal.

[0178] The detection circuit DC provides input information based on the detection signal.

[0179] This makes it possible to detect the distance from the approaching pointer to the detection area 241. Alternatively, it makes it possible to detect the position within the detection area 241 to which the pointer is closest.

[0180] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0181] (Embodiment 5) In this embodiment, a configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0182] 9A is a block diagram illustrating a configuration of an information processing device of one embodiment of the present invention, and FIG 9B and FIG 9C are projection views illustrating an example of the external appearance of the information processing device.

[0183] <Configuration example of information processing device> The information processing device 200 described in this embodiment includes an arithmetic device 210 and an input / output device 220 (see FIG. 9(A)). The input / output device 220 is electrically connected to the arithmetic device 210. The information processing device 200 may include a housing (see FIGS. 9(B) and 9(C)).

[0184] Configuration Example 1 of the Calculation Device 210 The arithmetic unit 210 is supplied with input information II or sensed information DS. The arithmetic unit 210 generates control information CI and image information VI based on the input information II or sensed information DS, and supplies the control information CI and image information VI.

[0185] The arithmetic device 210 includes a calculation unit 211 and a storage unit 212. The arithmetic device 210 also includes a transmission path 214 and an input / output interface 215.

[0186] The transmission path 214 is electrically connected to the calculation unit 211 , the storage unit 212 , and the input / output interface 215 .

[0187] 《Calculation section 211》 The calculation unit 211 has a function of executing a program, for example.

[0188] 《Storage section 212》 The storage unit 212 has a function of storing, for example, the program executed by the calculation unit 211, initial information, setting information, images, and the like.

[0189] Specifically, a hard disk, a flash memory, a memory including a transistor including an oxide semiconductor, or the like can be used.

[0190] Input / output interface 215, transmission path 214 The input / output interface 215 includes a terminal or wiring and has a function of supplying information and receiving information. For example, the input / output interface 215 can be electrically connected to the transmission path 214. The input / output interface 215 can also be electrically connected to the input / output device 220.

[0191] The transmission path 214 includes wiring and has a function of supplying information and receiving information. For example, the transmission path 214 can be electrically connected to the input / output interface 215. The transmission path 214 can also be electrically connected to the calculation unit 211, the storage unit 212, or the input / output interface 215.

[0192] Example of the configuration of the input / output device 220 The input / output device 220 supplies input information II and sensed information DS. The input / output device 220 is supplied with control information CI and image information VI (see FIG. 9(A)).

[0193] For example, keyboard scan code, position information, button operation information, audio information, image information, etc. can be used as the input information II. Alternatively, for example, illuminance information, posture information, acceleration information, direction information, pressure information, temperature information, humidity information, etc. of the environment in which the information processing device 200 is used can be used as the detection information DS.

[0194] For example, a signal for controlling the luminance, saturation, or hue of the image information VI may be used as the control information CI, or a signal for changing the display of a part of the image information VI may be used as the control information CI.

[0195] The input / output device 220 includes a display unit 230, an input unit 240, and a detection unit 250. For example, the input / output device described in the fourth embodiment can be used for the input / output device 220. The input / output device 220 can include a communication unit 290.

[0196] Configuration example of display unit 230 The display unit 230 displays the image information VI based on the control information CI. For example, the display device described in the third embodiment can be used for the display unit 230.

[0197] Example of configuration of input unit 240 The input unit 240 generates input information II. For example, the input unit 240 has a function of supplying position information.

[0198] For example, a human interface or the like can be used for the input unit 240 (see FIG. 9(A)). Specifically, a keyboard, a mouse, a touch sensor, a microphone, a camera, or the like can be used for the input unit 240.

[0199] It is also possible to use a touch sensor having an area overlapping with the display unit 230. Note that an input / output device including the display unit 230 and a touch sensor having an area overlapping with the display unit 230 can be called a touch panel or a touch screen.

[0200] For example, a user can perform various gestures (such as tapping, dragging, swiping, or pinching in) using a finger that touches the touch panel as a pointer.

[0201] For example, the computing device 210 can analyze information such as the position or trajectory of a finger touching the touch panel, and when the analysis result satisfies a predetermined condition, it can determine that a predetermined gesture has been provided. This allows the user to provide a predetermined operation command that is previously associated with a predetermined gesture by using the gesture.

[0202] As one example, a user can provide a "scroll command" to change the displayed position of image information by using a gesture of moving a finger in contact with the touch panel along the touch panel.

[0203] The user can also provide a "drag command" to pull out and display the navigation panel NP at the edge of the area 231 by using a gesture of moving a finger in contact with the edge of the area 231 (see FIG. 9(C)). The user can also provide a "leaf-through command" to flip through the index image IND, parts of other pages, or thumbnail images TN of other pages in a predetermined order on the navigation panel NP by using a gesture of moving the position where the finger is pressed firmly, or by using the pressure of the finger. This makes it possible to turn the pages of an e-book terminal in the same way as flipping through the pages of a paper book. Or, the user can use the thumbnail image TN or index image IND to find a predetermined page.

[0204] Example of configuration of detection unit 250 The detection unit 250 generates detection information DS. For example, the detection unit 250 has a function of detecting the illuminance of the environment in which the information processing device 200 is used, and a function of supplying the illuminance information.

[0205] The detection unit 250 has a function of detecting the surrounding state and supplying detection information, specifically, illuminance information, attitude information, acceleration information, direction information, pressure information, temperature information, humidity information, and the like.

[0206] For example, the detection unit 250 may use a photodetector, a posture detector, an acceleration sensor, a direction sensor, a GPS (Global Positioning System) signal receiving circuit, a pressure-sensitive switch, a pressure sensor, a temperature sensor, a humidity sensor, a camera, or the like.

[0207] 《Communication Section 290》 The communication unit 290 has a function of supplying information to the network and acquiring information from the network.

[0208] 《Case》 The housing has a function of housing the input / output device 220 or the arithmetic device 210. Alternatively, the housing has a function of supporting the display unit 230 or the arithmetic device 210.

[0209] This makes it possible to generate control information CI based on input information II or detection information DS. Or, it is possible to display image information VI based on input information II or detection information DS.

[0210] In addition, these configurations cannot be clearly separated, and one configuration may serve as another configuration or may include a part of another configuration. For example, a touch panel in which a touch sensor is superimposed on a display panel is both a display unit and an input unit.

[0245] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0246] (Embodiment 7) In this embodiment, a configuration example of an electronic device including a functional panel of one embodiment of the present invention will be described.

[0247] 13A shows a perspective view of a glasses-type electronic device 5700. The electronic device 5700 includes a pair of display panels 5701, a pair of housings 5702, a pair of optical members 5703, a pair of mounting portions 5704, a frame 5707, nose pads 5708, and the like.

[0248] The electronic device 5700 can project an image displayed on the display panel 5701 onto a display area 5706 of the optical member 5703. Since the optical member 5703 is translucent, the user can see the image displayed in the display area 5706 superimposed on a transmitted image visually recognized through the optical member 5703. Therefore, the electronic device 5700 is an electronic device capable of AR display.

[0249] One or both of the housings 5702 may be provided with a camera capable of capturing an image of the front. The housing 5702 may have a wireless communication device that can supply a video signal or the like to the housing 5702. Note that instead of or in addition to the wireless communication device, a connector to which a cable through which a video signal or a power supply potential can be connected may be provided. By providing an acceleration sensor such as a gyro sensor in the housing 5702, the direction of the user's head can be detected and an image according to the direction can be displayed in the display region 5706.

[0250] A processor may be provided in one or both of the housings 5702. The processor has a function of controlling various components of the electronic device 5700, such as a camera, a wireless communication device, and a pair of display panels 5701, a function of generating an image, and the like. The processor may have a function of generating a composite image for AR display.

[0251] In addition, the wireless communication device can communicate data with external devices. For example, data transmitted from the outside can be output to the processor, and the processor can generate image data for AR display based on the data. Examples of data transmitted from the outside include image data and data including bioinformation transmitted from a biosensor device.

[0252] 13B, a method for projecting an image onto a display region 5706 of the electronic device 5700 will be described. A display panel 5701 is provided inside a housing 5702. A reflector 5712 is provided on an optical member 5703, and a reflecting surface 5713 functioning as a half mirror is provided on a portion of the optical member 5703 that corresponds to the display region 5706.

[0253] Light 5715 emitted from display panel 5701 is reflected by reflector 5712 toward optical member 5703. Inside optical member 5703, light 5715 is repeatedly totally reflected by the end face of optical member 5703, and reaches reflecting surface 5713, whereby an image is projected onto reflecting surface 5713. This allows the user to visually recognize both light 5715 reflected by reflecting surface 5713 and transmitted light 5716 transmitted through optical member 5703 (including reflecting surface 5713).

[0254] 13 shows an example in which the reflector 5712 and the reflecting surface 5713 each have a curved surface. This allows for greater freedom in optical design compared to when these surfaces are flat, and allows for a thinner optical member 5703. The reflector 5712 and the reflecting surface 5713 may also be flat.

[0255] A member having a mirror surface, preferably having a high reflectance, can be used as the reflector 5712. Also, a half mirror utilizing the reflection of a metal film may be used as the reflector surface 5713, but the transmittance of the transmitted light 5716 can be increased by using a prism utilizing total reflection.

[0256] Here, the housing 5702 may have a lens between the display panel 5701 and the reflector 5712. In this case, the housing 5702 preferably has a mechanism for adjusting the distance between the lens and the display panel 5701 and the angle between them. This makes it possible to adjust the focus and enlarge or reduce an image. For example, one or both of the lens and the display panel 5701 may be configured to be movable in the optical axis direction.

[0257] In addition, the housing 5702 preferably has a mechanism capable of adjusting the angle of the reflector 5712. It is possible to change the position of the display area 5706 where an image is displayed by changing the angle of the reflector 5712. This makes it possible to place the display area 5706 at an optimal position according to the position of the user's eyes.

[0258] In addition, the housing 5702 is preferably provided with a battery 5717 and a wireless power supply module 5718. By providing the battery 5717, the electronic device 5700 can be used without connecting a separate battery, thereby improving convenience. In addition, by providing the wireless power supply module 5718, charging can be performed wirelessly, thereby improving convenience and design. Furthermore, compared to charging by wire using a connector or the like, the risk of failure such as poor contact can be reduced, and the reliability of the electronic device 5700 can be improved.

[0259] The housing 5702 is provided with a touch sensor module 5719. The touch sensor module 5719 has a function of detecting that the outer surface of the housing 5702 is touched. FIG. 13B shows a state where the surface of the housing 5702 is touched with a finger 5720. The touch sensor module 5719 can detect a tap operation or a slide operation by a user and execute various processes. For example, a tap operation can execute a process such as pausing or resuming a video, and a slide operation can execute a process such as fast forwarding or rewinding. Furthermore, by providing the touch sensor module 5719 on each of the two housings 5702, the range of operations can be expanded.

[0260] Various touch sensors can be applied as the touch sensor module 5719. For example, various types can be adopted, such as a capacitance type, a resistive film type, an infrared type, an electromagnetic induction type, a surface acoustic wave type, an optical type, etc. In particular, it is preferable to apply a capacitance type or an optical type sensor to the touch sensor module 5719.

[0261] When an optical touch sensor is used, a photoelectric conversion element can be used as the light receiving element. The photoelectric conversion element may use an inorganic semiconductor or an organic semiconductor in the active layer.

[0262] The display device or a functional panel according to one embodiment of the present invention can be applied to the display panel 5701. Thus, the electronic device 5700 can provide an extremely high-definition display.

[0263] This embodiment mode can be implemented by appropriately combining at least a part of it with other embodiment modes described in this specification.

[0264] For example, when it is explicitly stated in this specification that X and Y are connected, the case where X and Y are electrically connected, the case where X and Y are functionally connected, and the case where X and Y are directly connected are considered to be disclosed in this specification, etc. Therefore, it is not limited to a specific connection relationship, for example, a connection relationship shown in a figure or text, and a connection relationship other than that shown in a figure or text is also considered to be disclosed in the figure or text.

[0265] Here, X and Y are objects (for example, a device, an element, a circuit, a wiring, an electrode, a terminal, a conductive film, a layer, etc.).

[0266] An example of a case where X and Y are directly connected is a case where an element that enables an electrical connection between X and Y (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.) is not connected between X and Y, and a case where X and Y are connected without an element that enables an electrical connection between X and Y (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.).

[0267] As an example of a case where X and Y are electrically connected, one or more elements (e.g., a switch, a transistor, a capacitance element, an inductor, a resistance element, a diode, a display element, a light-emitting element, a load, etc.) that enable the electrical connection between X and Y can be connected between X and Y. The switch has a function of controlling on / off. In other words, the switch has a function of being in a conductive state (on state) or a non-conductive state (off state) and controlling whether or not a current flows. Alternatively, the switch has a function of selecting and switching a path for the current to flow. The case where X and Y are electrically connected includes the case where X and Y are directly connected.

[0268] As an example of a case where X and Y are functionally connected, one or more circuits that enable the functional connection between X and Y (for example, logic circuits (inverters, NAND circuits, NOR circuits, etc.), signal conversion circuits (DA conversion circuits, AD conversion circuits, gamma correction circuits, etc.), potential level conversion circuits (power supply circuits (boosting circuits, step-down circuits, etc.), level shifter circuits that change the potential level of a signal, etc.), voltage sources, current sources, switching circuits, amplifier circuits (circuits that can increase the signal amplitude or current amount, operational amplifiers, differential amplifier circuits, source follower circuits, buffer circuits, etc.), signal generation circuits, memory circuits, control circuits, etc.) can be connected between X and Y. As an example, even if another circuit is sandwiched between X and Y, if a signal output from X is transmitted to Y, X and Y are considered to be functionally connected. Note that the case where X and Y are functionally connected includes the case where X and Y are directly connected and the case where X and Y are electrically connected.

[0269] In addition, when it is explicitly stated that X and Y are electrically connected, the following cases are considered to be disclosed in this specification etc.: when X and Y are electrically connected (i.e., when they are connected with another element or circuit between them), when X and Y are functionally connected (i.e., when they are functionally connected with another circuit between them), and when X and Y are directly connected (i.e., when they are connected without another element or circuit between them). In other words, when it is explicitly stated that they are electrically connected, the same content as when it is simply and explicitly stated that they are connected is considered to be disclosed in this specification etc.

[0270] For example, when the source (or the first terminal, etc.) of the transistor is electrically connected to X via (or without) Z1 and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via (or without) Z2, or when the source (or the first terminal, etc.) of the transistor is directly connected to a part of Z1, another part of Z1 is directly connected to X, the drain (or the second terminal, etc.) of the transistor is directly connected to a part of Z2, and another part of Z2 is directly connected to Y, it can be expressed as follows.

[0271] For example, it can be expressed as "X, Y, and the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor are electrically connected to each other, and are electrically connected in the order of X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y." Or, it can be expressed as "The source (or first terminal, etc.) of the transistor is electrically connected to X, the drain (or second terminal, etc.) of the transistor is electrically connected to Y, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are electrically connected in this order." Or, it can be expressed as "X is electrically connected to Y through the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor, and X, the source (or first terminal, etc.) of the transistor, the drain (or second terminal, etc.) of the transistor, and Y are provided in this connection order." By using expressions similar to these examples to specify the order of connections in a circuit configuration, the source (or first terminal, etc.) and drain (or second terminal, etc.) of a transistor can be distinguished and the technical scope can be determined.

[0272] Alternatively, as another way of expressing it, for example, it can be expressed as "the source (or the first terminal, etc.) of the transistor is electrically connected to X via at least a first connection path, the first connection path does not have a second connection path, the second connection path is a path between the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor via a transistor, the first connection path is a path via Z1, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via at least a third connection path, the third connection path does not have the second connection path, and the third connection path is a path via Z2." Alternatively, it can be expressed as "the source (or the first terminal, etc.) of the transistor is electrically connected to X via Z1 by at least a first connection path, the first connection path does not have a second connection path, the second connection path has a connection path via a transistor, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third connection path, and the third connection path does not have the second connection path." Alternatively, it can be expressed as follows: "The source (or first terminal, etc.) of the transistor is electrically connected to X via Z1 by at least a first electrical path, the first electrical path does not have a second electrical path, the second electrical path is an electrical path from the source (or first terminal, etc.) of the transistor to the drain (or second terminal, etc.) of the transistor, and the drain (or second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least a third electrical path, the third electrical path does not have a fourth electrical path, and the fourth electrical path is an electrical path from the drain (or second terminal, etc.) of the transistor to the source (or first terminal, etc.) of the transistor." By using an expression method similar to these examples to define the connection path in the circuit configuration, the source (or first terminal, etc.) and the drain (or second terminal, etc.) of the transistor can be distinguished to determine the technical scope.

[0273] Note that these representation methods are merely examples and are not limited to these representation methods. Here, X, Y, Z1, and Z2 are objects (for example, a device, an element, a circuit, a wiring, an electrode, a terminal, a conductive film, a layer, etc.).

[0274] In addition, even when components that are independent on a circuit diagram are shown as being electrically connected to each other, one component may have the functions of multiple components. For example, when a part of a wiring also functions as an electrode, one conductive film has both the functions of a wiring and an electrode. Therefore, the term "electrical connection" in this specification also includes such a case where one conductive film has the functions of multiple components. [Explanation of symbols]
