[0012] Note that the description of these objects does not preclude the existence of other objects. Note that one embodiment of the present application does not need to achieve all the above-described objects. Objects other than the above-described objects will be apparent from the description of the specification, the attached drawings, the claims, and the like, and can be extracted from the description.
[0013] Means for solving the technical problem
[0014] (1) One embodiment of the present application is a display panel 700 including a display region 231, a first functional layer 520A, a second functional layer 520B, and a first connection portion 591C(i, y).
[0015] The display region 231 includes a pixel 702(i, j). The pixel 702(i, j) includes a display element 550(i, j) and a pixel circuit 530(i, j).
[0016] The first functional layer 520A includes the pixel circuit 530(i, j) and a scan line G1(i), and the display element 550(i, j) is electrically connected to the pixel circuit 530(i, j).
[0017] The pixel circuit 530(i, j) is electrically connected to the scan line G1(i).
[0018] The second functional layer 520B includes a region overlapping with the first functional layer 520A, and includes a driver circuit GD and a wiring G2(i).
[0019] The driver circuit GD is provided so as to sandwich the pixel circuit 530(i, j) between the display element 550(i, j).
[0020] The wiring G2(i) is electrically connected to the scan line G1(i) at the first connection portion 591C(i, y), and is electrically connected to the driver circuit GD.
[0021] Thus, the degree of freedom of the configuration of the driver circuit GD can be increased. For example, the driver circuit GD can be configured so as to overlap with the display region 231. Further, the outer shape of the driver circuit GD does not need to follow the outer shape of the display panel 700. Further, the degree of freedom of the outer shape of the display panel 700 can be increased. For example, the outline of the display region 231 can use a curved line. Further, the outer shape of the display panel 700 can be reduced. As a result, a novel display panel with high convenience or reliability can be provided.
[0022] (2) Further, one embodiment of the present application is the above-described display panel 700 including the terminal 519C(j).
[0023] The first functional layer 520A includes the signal line S1(j), the auxiliary signal line S2(j), and the second connection portion 591D(j).
[0024] The signal line S1(j) is electrically connected to the pixel circuit 530(i, j), and the signal line S1(j) is electrically connected to the auxiliary signal line S2(j) at the second connection portion 591D(j).
[0025] The auxiliary signal line S2(j) includes a region that crosses the other signal line S1(j+1), and the auxiliary signal line S2(j) is electrically connected to the terminal 519C(j).
[0026] Thus, the degree of freedom of the configuration of the terminal 519C(j) can be increased. Alternatively, the degree of freedom of the outer shape of the display panel 700 can be increased. Alternatively, the outer shape of the display panel 700 can be reduced. As a result, a novel display panel with high convenience or reliability can be provided.
[0027] (3) Further, one embodiment of the present application is the above-described display panel in which the display region 231 includes one scan line G1(i) and another scan line G1(p), and the number of pixels electrically connected to the other scan line G1(p) is smaller than that electrically connected to the scan line G1(i).
[0028] (4) Further, one embodiment of the present application is the above-described display panel in which the display region 231 includes one signal line S1(j) and another signal line S1(q), and the number of pixels electrically connected to the other signal line S1(q) is smaller than that electrically connected to the signal line S1(j).
[0029] Thus, the degree of freedom of the outer shape of the display panel 700 can be increased. For example, the outline of the display region 231 can use a curved line. Further, the outer shape of the display panel can follow the display region that uses a curved line. Further, for example, the pixels can be arranged along a curved line. As a result, a novel display panel with high convenience or reliability can be provided.
[0030] (5) In addition, one aspect of the present invention is the above-described display panel, wherein the display area 231 includes a set of pixels 702(i, 1) to pixels 702(i, n) and another set of pixels 702(1, j) to pixels 702(m, j).
[0031] A group of pixels 702(i,1) to 702(i,n) includes pixel 702(i,j), and the group of pixels 702(i,1) to 702(i,n) is arranged in the row direction. In addition, the group of pixels 702(i,1) to 702(i,n) is electrically connected to scan line G1(i).
[0032] Another set of pixels 702(1,j) to 702(m,j) includes pixel 702(i,j), and this other set of pixels 702(1,j) to 702(m,j) is arranged in a column direction that intersects the row direction. Furthermore, this other set of pixels 702(1,j) to 702(m,j) is electrically connected to signal line S1(j).
[0033] This allows image data to be supplied to multiple pixels. The result is the ability to provide novel display panels with superior convenience and reliability.
[0034] (6) Furthermore, one aspect of the present invention is the aforementioned display panel comprising a set of connecting portions 591C(i, 1) to connecting portions 591C(i, h). Note that h is a natural number greater than or equal to 1, and preferably a natural number greater than 1 and less than n.
[0035] A set of connection portions 591C(i, 1) to connection portions 591C(i, h) includes a first connection portion 591C(i, y), and a scan line G1(i) is electrically connected to wiring G2(i) in the set of connection portions 591C(i, 1) to connection portions 591C(i, h).
[0036] This allows for electrical connection between scan line G1(i) and wiring G2(i). Alternatively, it reduces the probability of poor connection. The result is the ability to provide novel display panels with superior convenience or reliability.
[0037] (7) In addition, one aspect of the present invention is the above-described display panel 700, wherein the first connection portion 591C(i, y) includes a conductive member CP, which has the function of electrically connecting the scan line G1(i) and the wiring G2(i).
[0038] This allows for electrical connection between scan line G1(i) and wiring G2(i). Alternatively, it reduces the probability of poor connection. The result is the ability to provide novel display panels with superior convenience or reliability.
[0039] (8) In addition, one aspect of the present invention is a display device including the above-described display panel 700 and control unit 238.
[0040] The control unit 238 is supplied with image data V1 and control data CI. The control unit 238 generates data V11 based on the image data V1 and generates a control signal SP based on the control data CI. In addition, the control unit 238 supplies data V11 and control signal SP.
[0041] The display panel 700 is supplied with data V11 and control signal SP. Note that the drive circuit GD operates according to the control signal SP, and the pixels 702(i,j) are displayed according to the data V11.
[0042] Therefore, display elements can be used to display image data. As a result, novel display devices with excellent convenience or reliability can be provided.
[0043] (9) In addition, one aspect of the present invention is an input / output device including an input section 240 and a display section 230.
[0044] The display unit 230 includes the aforementioned display panel 700, and the input unit 240 includes a detection area 241.
[0045] The input unit 270 detects objects approaching the detection area 241, which includes the area overlapping with pixel 702(i,j).
[0046] Therefore, objects approaching or overlapping with the display area can be detected while displaying image data on the display unit. Alternatively, a finger or similar object approaching the display unit can be used as an indicator to input position data. Or, the position data can be correlated with image data displayed on the display unit. As a result, novel input / output devices with excellent convenience and reliability can be provided.
[0047] (10) In addition, one aspect of the present invention includes one or more of a keyboard, hardware buttons, pointing device, touch sensor, illuminance sensor, image capturing device, sound input device, gaze input device and posture detection device, as well as a data processing device for the aforementioned display panel.
[0048] Therefore, the computing device can generate image data or control data based on data supplied using various input devices. As a result, novel data processing devices with excellent convenience and reliability can be provided.
[0049] In the accompanying drawings of this specification, the constituent elements are shown as independent blocks according to their functions. However, in reality, it is difficult to completely divide the constituent elements according to their functions, and a constituent element may involve multiple functions.
[0050] In this specification, the names of the source and drain terminals of a transistor are interchanged according to 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. Although for convenience, the connection relationship of the transistor is sometimes assumed to be fixed in describing the source and drain in this specification, in practice, the names of the source and drain are interchanged according to the aforementioned potential relationship.
[0051] In this specification, the source of a transistor refers to the source region of a semiconductor film used as part of the active layer, or the source electrode connected to the semiconductor film. Similarly, the drain of a transistor refers to the drain region of a semiconductor film, or the drain electrode connected to the semiconductor film. Furthermore, the gate refers to the gate electrode.
[0052] In this specification, a transistor connected in series means, for example, that only one of the source and drain of the first transistor is connected to one of the source and drain of the second transistor. Conversely, a transistor connected in parallel means that one of the source and drain of the first transistor is connected to one of the source and drain of the second transistor, and the other of the source and drain of the first transistor is connected to the other of the source and drain of the second transistor.
[0053] In this specification, connection refers to electrical connection, which is equivalent to a state capable of supplying or transmitting current, voltage, or potential. Therefore, a connection 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 in a manner capable of supplying or transmitting current, voltage, or potential.
[0054] Even when independent components on the circuit diagram in this specification are connected to each other, there are actually cases where a single conductive film functions as multiple components, such as when a portion of the wiring is used as an electrode. The scope of connections in this specification includes such cases where a single conductive film functions as multiple components.
[0055] In addition, in this specification, one of the first electrode and the second electrode of the transistor is the source electrode, and the other is the drain electrode.

Furthermore, one embodiment of the invention does not necessarily require all of the aforementioned effects. Effects other than those described above can be naturally understood and derived from the description, drawings, claims, etc. Brief description of the attached figures

The driving circuit is arranged such that it sandwiches the pixel circuit between itself and the display element. The wiring is electrically connected to the scan lines at the first connecting portion and is also electrically connected to the driving circuit.
[0078] This increases the flexibility in configuring the drive circuitry. For example, the drive circuitry can be configured to overlap with the display area. Furthermore, it increases the flexibility in the shape of the display panel. For example, the outline of the display area can use curves. Alternatively, the shape of the display panel can be reduced.

[0092] Note that in this specification, variables with integer values greater than 1 are sometimes used as symbols. For example, sometimes (p) of a variable p containing integer values greater than 1 is used as part of the symbol for any one of the maximum number of components.

[0093] <Example 1 of a display panel structure.>
[0094] The display panel 700 described in this embodiment includes a display area 231, a functional layer 520A, a functional layer 520B, and a first connecting portion 591C(i, y) (see reference). Figure 1A and Figure 1B ).
[0095] Example 1 of the structure of display area 231.
[0096] Display area 231 includes pixels 702(i, j).
[0097] Example 1 of the structure of pixel 702(i, j).
[0098] Pixel 702(i,j) includes display element 550(i,j) and pixel circuit 530(i,j) (see reference) Figure 1B and Figure 2B ).
[0099] Example 1 of the structure of functional layer 520A.
[0100] Functional layer 520A includes pixel circuits 530(i, j) and scan line G1(i) (see reference). Figure 2B and Figure 4A ).
[0101] Example 1 of the structure of display element 550(i,j).
[0102] Display element 550(i,j) is electrically connected to pixel circuit 530(i,j) (see reference). Figure 1B , Figure 2B and Figure 5 ).
[0103] Display element 550(i,j) has the function of emitting light, and display element 550(i,j) includes a layer 553(j) containing a light-emitting material (see reference). Figure 5 ).
[0104] For example, a display element that emits light can be used as display element 550(i,j). Specifically, organic electroluminescent elements, inorganic electroluminescent elements, light-emitting diodes such as Micro-LEDs or QDLEDs (Quantum Dot LEDs) can be used as display element 550(i,j).
[0105] Example 1 of a structure containing layer 553(j) of luminescent material.
[0106] For example, a strip-shaped stacked material that is longer along the column direction along the signal line S1(j) can be used for layer 553(j) containing the luminescent material.
[0107] Specifically, materials that emit light with different hues can be used for layers 553(j), 553(j+1), and 553(j+2) that contain light-emitting materials. Thus, for example, the hue of the light emitted by the display element 550(i,j) can be different for each column.
[0108] For example, materials that emit blue light, green light, and red light can be used as materials that emit light of different hues.
[0109] Example 2 of a structure containing layer 553(j) of luminescent material.
[0110] For example, a stacked material that emits white light can be used for layer 553(j) containing the luminescent material.
[0111] Specifically, materials that emit light of different hues can be used in layer 553(j) which contains luminescent materials.
[0112] For example, a laminated material comprising a layer of luminescent material containing a fluorescent material emitting blue light and a layer of material other than a fluorescent material emitting green or red light can be used for layer 553(j) containing luminescent material. Alternatively, a laminated material comprising a layer of luminescent material containing a fluorescent material emitting blue light and a layer of material other than a fluorescent material emitting yellow light can be used for layer 553(j) containing luminescent material.
[0113] For example, the light-emitting unit can be used in layer 553(j) which contains a light-emitting material. The light-emitting unit has a region in which electrons injected from one side recombine with holes injected from the other side. In addition, the light-emitting unit contains a light-emitting material that emits the energy generated by the recombination of electrons and holes in the form of light.
[0114] For example, multiple light-emitting units and an intermediate layer can be used as layer 553(j) containing light-emitting material. The intermediate layer has a region sandwiched between two light-emitting units. The intermediate layer has a charge-generating region and functions to supply holes to the light-emitting units disposed on the cathode side and electrons to the light-emitting units disposed on the anode side. In addition, the structure having multiple light-emitting units and an intermediate layer is sometimes referred to as a series-type light-emitting element.
[0115] For example, a light-emitting unit containing a material that emits light of one hue and a light-emitting unit containing a material that emits light of other hues can be used in layer 553(j) containing light-emitting material.
[0116] For example, high molecular weight compounds (oligomers, dendritic polymers, polymers, etc.) and medium molecular weight compounds (compounds between low and high molecular weights: with a molecular weight of 400 or more and 4000 or less) can be used in layer 553(j) containing luminescent materials.
[0117] Electrode 551(i,j), Electrode 552
[0118] Electrode 551(i,j) is electrically connected to pixel circuit 530(i,j) at connection portion 591A (see reference).Figure 5 ).
[0119] For example, materials suitable for wiring or the like can be used for electrodes 551(i,j) or 552. Specifically, materials that are transparent to visible light can be used for electrodes 551(i,j) or 552.
[0120] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide with gallium added, 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.
[0121] For example, a metal film that allows a portion of the light to pass through and reflects the rest can be used as electrode 551(i,j) or electrode 552. Thus, for example, the distance between electrode 551(i,j) and electrode 552 can be adjusted. Alternatively, a tiny resonator structure can be provided in display element 550(i,j). Or, light of a specific wavelength can be extracted more efficiently compared to other light. Or, light with a narrow half-width of the spectrum can be extracted. Or, light of vivid colors can be extracted.
[0122] For example, a film that effectively reflects light can be used for electrode 551(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.
[0123] Example 1 of the structure of pixel circuit 530(i,j).
[0124] Pixel circuit 530(i,j) is electrically connected to scan line G1(i) (refer to...) Figure 2B and Figure 4A ).
[0125] For example, switches, transistors, diodes, resistors, inductors, or capacitors can be used in pixel circuit 530(i,j).
[0126] Pixel circuit 530(i,j) includes switch SW2, transistor M, and capacitor C21. For example, the transistor can be used for switch SW2.
[0127] Example 1 of the structure of switch SW2.
[0128] The transistor used to switch SW2 comprises semiconductors.
[0129] The transistor includes a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see reference). Figure 4B ).
[0130] The semiconductor film 508 includes a region 508A electrically connected to the conductive film 512A and a region 508B electrically connected to the conductive film 512B. The semiconductor film 508 also includes a region 508C between regions 508A and 508B.
[0131] The conductive film 504 includes a region overlapping with region 508C. The conductive film 504 functions as a gate electrode.
[0132] The insulating film 506 includes a region sandwiched between the semiconductor film 508 and the conductive film 504. The insulating film 506 functions as a gate insulating film.
[0133] Conductive film 512A functions as either a source electrode or a drain electrode. Conductive film 512B functions as either a source electrode or a drain electrode. Note that either conductive film 512A or conductive film 512B can be used for wiring G2(i).
[0134] Example 1 of the structure of transistor M.
[0135] For example, a semiconductor film that can be formed through the same process can be used as a transistor and transistor M as switch SW2. Alternatively, the same structure can be used as a transistor and transistor M as switch SW2.
[0136] Alternatively, the conductive film 524 can be used in a transistor. The conductive film 524 includes a region between the conductive film 524 and the conductive film 504, with a semiconductor film 508 sandwiched between them. The conductive film 524 functions as a second gate electrode. The conductive film 524 can, for example, be electrically connected to the conductive film 504.
[0137] Alternatively, for example, semiconductor films that can be formed through the same process can be used for transistors in drive circuits and pixel circuits.
[0138] For example, bottom-gate transistors or top-gate transistors can be used as pixel circuits 530(i,j). Alternatively, they can be used as transistors in driving circuits.
[0139] Example 1 of the structure of semiconductor film 508.
[0140] For example, a semiconductor containing a Group 14 element can be used in semiconductor film 508. Specifically, a semiconductor containing silicon can be used in semiconductor film 508.
[0141] [Hydrogenated amorphous silicon]
[0142] 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. Thus, for example, a display panel with less uniformity can be provided compared to a display panel using polycrystalline silicon for the semiconductor film 508. Alternatively, it is easier to achieve large-scale display panels.
[0143] [Polycrystalline Silicon]
[0144] For example, polycrystalline silicon can be used in the semiconductor film 508. This allows, for example, a higher field-effect mobility than that achieved with a transistor using hydrogenated amorphous silicon in the semiconductor film 508. Alternatively, for example, a higher driving capability than that achieved with a transistor using hydrogenated amorphous silicon in the semiconductor film 508 can be achieved. Or, for example, a higher pixel aperture ratio than that achieved with a transistor using hydrogenated amorphous silicon in the semiconductor film 508 can be achieved.
[0145] Alternatively, for example, higher reliability can be achieved than that of transistors using hydrogenated amorphous silicon in semiconductor film 508.
[0146] Alternatively, for example, the temperature required to manufacture transistors can be lower than that required for transistors made from monocrystalline silicon.
[0147] Alternatively, the semiconductor film for the transistor used in the driving circuit and the semiconductor film for the transistor used in the pixel circuit can be formed in the same process. Alternatively, the driving 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.
[0148] Monocrystalline silicon
[0149] For example, monocrystalline silicon can be used in semiconductor films. This, for example, allows for higher resolution display panels compared to those using hydrogenated amorphous silicon in the semiconductor film 508. Alternatively, for example, it allows for display panels with less uniformity compared to those using polycrystalline silicon in the semiconductor film 508. Alternatively, for example, it allows for the provision of smart glasses or head-mounted displays.
[0150] Example 2 of the structure of semiconductor film 508.
[0151] For example, metal oxides can be used for the semiconductor film 508. This extends the time the pixel circuit can hold the image signal compared to pixel circuits using transistors with amorphous silicon as the semiconductor film. Specifically, flickering can be suppressed, and a selection signal can be supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than 1 time / min. As a result, user fatigue of the data processing device can be reduced. Furthermore, power consumption for driving can be reduced.
[0152] For example, an oxide semiconductor transistor can be used. Specifically, an oxide semiconductor containing indium or an oxide semiconductor containing indium, gallium, and zinc can be used in a semiconductor film.
[0153] For example, a transistor with a lower 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.
[0154] For example, a 25nm thick film containing indium, gallium, and zinc can be used as semiconductor film 508.
[0155] For example, a conductive film 504 can be used as a conductive film having a thickness of 10 nm containing tantalum and nitrogen and a film having a thickness of 300 nm containing copper, which are stacked together. In addition, the copper-containing film includes a region in which the tantalum and nitrogen-containing film is sandwiched between the copper-containing film and the insulating film 506.
[0156] 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 insulating film 506. Additionally, the silicon and nitrogen film includes a region between the silicon and nitrogen film and the semiconductor film 508 containing the silicon, oxygen, and nitrogen film.
[0157] For example, a conductive film consisting of a 50 nm thick film containing tungsten, a 400 nm thick film containing aluminum, and a 100 nm thick film containing titanium can be sequentially stacked as conductive film 512A or conductive film 512B. Furthermore, the tungsten-containing film includes a region in contact with the semiconductor film 508.
[0158] Furthermore, for example, a production line using amorphous silicon as a semiconductor for bottom-gate transistors can be easily converted to a production line using oxide semiconductors as semiconductors for bottom-gate transistors. Similarly, for example, a production line using polycrystalline silicon as a semiconductor for top-gate transistors can be easily converted to a production line using oxide semiconductors as top-gate transistors. Either of these conversions can effectively utilize existing production lines.
[0159] This allows for the suppression of flickering, reduction of power consumption, smooth display of fast-moving images, and the display of photographs with rich grayscale levels. The result is the provision of novel display panels offering superior convenience and reliability.
[0160] Example 3 of the structure of semiconductor film 508.
[0161] For example, compound semiconductors can be used as semiconductors in transistors. Specifically, semiconductors containing gallium arsenide can be used.
[0162] For example, organic semiconductors can be used as semiconductors in transistors. Specifically, organic semiconductors containing polyphenylene or graphene can be used as semiconductor films.
[0163] Example 1 of the structure of functional layer 520B.
[0164] Functional layer 520B includes the region that overlaps with functional layer 520A (see reference). Figure 1B Additionally, functional layer 520B includes driver circuitry GD and wiring G2(i) (see reference). Figure 4A For example, insulating film 521B can be used in functional layer 520B. For example, materials that can be used in insulating film 521 (described later) can be used in insulating film 521B.
[0165] Example 1 of the structure of a driver circuit GD.
[0166] The driving circuit GD is arranged such that the pixel circuit 530(i,j) is sandwiched between the display element 550(i,j) (see reference). Figure 1B ).
[0167] The drive circuit GD supplies a selection signal. For example, the drive circuit GD supplies the selection signal to the wiring G2(i) and to the scan line G1(i) through the connection part 591C(i, y).
[0168] For example, transistor MD can be used in drive circuit GD (see reference). Figure 4B Additionally, structures that can be used for transistor M can be used for transistor MD.
[0169] Example 1 of the structure of scan line G1(i).
[0170] Scan line G1(i) includes the region sandwiched between the driving circuit GD and a set of pixel circuits 530(i,1) to pixel circuits 530(i,n) (see reference). Figure 3A and Figure 4A Therefore, the scan line G1(i) can, for example, shield against noise generated by the drive circuit GD. Additionally, it can shield against noise generated by the pixel circuit 530(i,j). Furthermore, it can prevent malfunctions of the pixel circuit 530(i,j) caused by noise. Additionally, it can prevent malfunctions of the drive circuit GD caused by noise. Alternatively, it can prevent image quality degradation caused by noise.
[0171] Example 1 of the structure of wiring G2(i).
[0172] Wiring G2(i) is electrically connected to scan line G1(i) at connection portion 591C(i, y). Additionally, wiring G2(i) is electrically connected to drive circuit GD. For example, openings formed in insulating films 521B, 518, and 516 can be used as connection portions 591C(i, y) (see reference). Figure 4A and Figure 4B ).
[0173] This increases the flexibility in configuring the drive circuit GD. For example, the drive circuit GD can be configured to overlap with the display area 231. Furthermore, it is not necessary for the shape of the drive circuit GD to follow the shape of the display panel 700. Additionally, the shape of the display panel 700 can be more flexible. For example, the outline of the display area 231 can use a curve. Furthermore, the shape of the display panel 700 can be reduced in size. Alternatively, the shape of the display panel can be adjusted to a specified shape by cutting off the outer periphery. As a result, novel display panels with excellent convenience and reliability can be provided.
[0174] Example 2 of the structure of wiring G2(i).
[0175] For example, a conductive film with a lower resistance than scan line G1(i) can be used for wiring G2(i). Alternatively, a conductive film with a narrower width than scan line G1(i) can be used for wiring G2(i).
[0176] This reduces the resistance between the drive circuit GD and the pixel circuit 530(i,j). Additionally, it reduces the degree of distortion in the waveform of the control signal SP. Alternatively, it reduces feedthrough. The result is a novel display panel with superior convenience and reliability.
[0177] <Example 2 of display panel structure.>
[0178] Additionally, the display panel 700 described in this embodiment includes terminal 519C(j) (see reference). Figure 1B and Figure 7B ).
[0179] Example 2 of the structure of functional layer 520A.
[0180] Functional layer 520A includes signal line S1(j), auxiliary signal line S2(j), and connection part 591D(j) (see reference). Figure 4A ).
[0181] Example 1 of the structure of signal line S1(j).
[0182] Signal line S1(j) is electrically connected to pixel circuit 530(i,j). Additionally, signal line S1(j) is electrically connected to auxiliary signal line S2(j) at connection portion 591D(j) (see reference). Figure 4B ).
[0183] Example 1 of the structure of auxiliary signal line S2(j).
[0184] The auxiliary signal line S2(j) includes the area where it intersects with other signal lines S1(j+1), and the auxiliary signal line S2(j) is electrically connected to terminal 519C(j) (see reference). Figure 3B and Figure 7B For example, auxiliary signal line S2(j) crosses signal line S1(j+1).
[0185] Furthermore, the connecting portion 591D(j) provided not at the end of the signal line S1(j) but in the middle of the signal line S1(j) electrically connects the signal line S1(j) to the auxiliary signal line S2(j), thereby averaging the resistance between a pixel circuit 530(i,j) selected from another set of pixel circuits 530(1,j) to pixel circuits 530(m,j) and terminal 519C(j).
[0186] This increases the flexibility in the configuration of terminal 519C(j). Furthermore, it increases the flexibility in the shape of the display panel 700. Additionally, it allows for a reduction in the size of the display panel 700. Furthermore, the pixel circuit 530(i,j) can average the degree of distortion in the waveform of the data V11 supplied from terminal 519C(j). As a result, a novel display panel with excellent convenience and reliability can be provided.
[0187] <Example 3 of a display panel structure.>
[0188] Furthermore, in the display panel 700 described in this embodiment, the display area 231 includes scan lines G1(i) and G1(p) (see reference). Figure 2A Compared to scan line G1(i), there are fewer pixels electrically connected to scan line G1(p).
[0189] For example, compared to scan line G1(i), there are fewer pixels electrically connected to scan line G1(i+20) (see reference). Figure 7A Specifically, the number of pixels electrically connected to scan line G1(i+20) is six fewer than the number of pixels electrically connected to scan line G1(i).
[0190] <Example 4 of a display panel structure.>
[0191] Furthermore, in the display panel 700 described in this embodiment, the display area 231 includes signal line S1(j) and signal line S1(q) (see reference). Figure 2A Compared to signal line S1(j), there are fewer pixels electrically connected to signal line S1(q).
[0192] For example, compared to signal line S1(i), there are fewer pixels electrically connected to signal line S1(i-10) (see reference). Figure 7B Specifically, the number of pixels electrically connected to signal line S1(i-10) is three fewer than the number of pixels electrically connected to signal line S1(i).
[0193] This increases the flexibility in the shape of the display panel 700. For example, the outline of the display area 231 can be curved. Furthermore, the curved display area can be aligned with the shape of the display panel. Additionally, pixels can be arranged along the curve, for example. As a result, novel display panels with excellent convenience and reliability can be provided.
[0194] <Example 5 of a display panel structure.>
[0195] Furthermore, in the display panel 700 described in this embodiment, the display area 231 includes a group of pixels 702(i, 1) to 702(i, n) and another group of pixels 702(1, j) to 702(m, j) (see reference). Figure 10A and Figure 10B ).
[0196] Additionally, display area 231 includes conductive film VCOM2 (not shown) and conductive film ANO.
[0197] Example 1 of a group of pixels.
[0198] A group of pixels 702(i, 1) to 702(i, n) includes pixel 702(i, j), and the group of pixels 702(i, 1) to 702(i, n) is arranged in the row direction (indicated by arrow R1 in the figure). Additionally, the group of pixels 702(i, 1) to 702(i, n) is electrically connected to scan line G1(i).
[0199] Another set of pixels 702(1,j) to 702(m,j) includes pixel 702(i,j), and this other set of pixels 702(1,j) to 702(m,j) is arranged in a column direction (indicated by arrow C1 in the figure) that intersects the row direction. Furthermore, this other set of pixels 702(1,j) to 702(m,j) is electrically connected to signal line S1(j).
[0200] This allows image data to be supplied to multiple pixels. The result is the ability to provide novel display panels with superior convenience and reliability.
[0201] <Example 6 of a display panel structure.>
[0202] Additionally, the display panel 700 described in this embodiment includes a set of connecting portions 591C(i, 1) to a set of connecting portions 591C(i, h) (see reference). Figure 7A Furthermore, h is a natural number greater than or equal to 1, preferably a natural number greater than 1 and less than n. For example, when the number of connections is greater than 1, the probability of poor connections can be reduced, and when the number of connections is less than n, the probability of short circuits between connections in adjacent rows can be reduced. Specifically, connection 591C(i, y) is less likely to short circuit with connection 591C(i-1, y) or connection 591C(i+1, y).
[0203] Furthermore, the connecting portion 591C(i,y) provided not at the end of the scan line G1(i) but in the middle of the scan line G1(i) electrically connects the scan line G1(i) to the wiring G2(i), thereby averaging the resistance between one pixel circuit 530(i,j) selected from a set of pixel circuits 530(i,1) to pixel circuits 530(i,n) and the driving circuit GD.
[0204] Furthermore, since the scan line G1(i) is electrically connected to the wiring G2(i) through a set of connection portions 591C(i,1) to a set of connection portions 591C(i,h), the resistance between a pixel circuit 530(i,j) selected from a set of pixel circuits 530(i,1) to pixel circuits 530(i,n) and the drive circuit GD can be averaged.
[0205] This can average out the degree of distortion occurring in the waveform of the control signal SP. Alternatively, it can average out the degree of feedthrough. Or, it can reduce display non-uniformity. The result is that novel display panels with excellent convenience or reliability can be provided.
[0206] Example 1 of a structure from a set of connecting parts 591C(i, 1) to a set of connecting parts 591C(i, h).
[0207] A set of connecting portions 591C(i, 1) to a set of connecting portions 591C(i, h) includes a connecting portion 591C(i, y), and the scan line G1(i) is electrically connected to the wiring G2(i) at a set of connecting portions 591C(i, 1) to a set of connecting portions 591C(i, h) (see reference). Figure 7A ).
[0208] This allows for electrical connection between scan line G1(i) and wiring G2(i). Alternatively, it reduces the probability of poor connection. The result is the ability to provide novel display panels with superior convenience or reliability.
[0209] Example 2 of the structure of the connecting part 591C(i, y).
[0210] Furthermore, in the display panel 700 described in this embodiment, the connecting portion 591C(i, y) includes a conductive member CP (refer to...). Figure 8 and Figure 9 ).
[0211] Example 1 of the structure of a conductive component (CP).
[0212] The conductive component CP has the function of electrically connecting the scan line G1(i) and the wiring G2(i).
[0213] For example, conductive particles can be used as conductive components (CP).
[0214] For example, particles with a size of 1 μm or more and 200 μm or less, preferably 3 μm or more and 150 μm or less, having a spherical, columnar, or fibrous shape, can be used as particles CP. For example, particles covered with a conductive material containing nickel or gold can be used. Specifically, particles containing polystyrene, acrylic resin, or titanium dioxide can be used. Specifically, the conductive component CP can be dispersed in the insulating material 521C. For example, synthetic rubber, thermosetting resin, thermoplastic resin, adhesive, etc., can be used in the insulating material 521C.
[0215] For example, a convex structure KB can be used for the connection portion 591C(i, y). Alternatively, a conductive component CP formed on the structure KB can be used.
[0216] This allows for electrical connection between scan line G1(i) and wiring G2(i). Alternatively, it reduces the probability of poor connection. The result is the ability to provide novel display panels with superior convenience or reliability.
[0217] <Example 6 of a display panel structure.>
[0218] Additionally, the display panel 700 includes a substrate 510, a substrate 770, and an insulating film 501C (see reference). Figure 4A ).
[0219] The insulating film 501C includes a region sandwiched between the substrate 770 and the substrate 510, and the insulating film 501C also includes a region sandwiched between the functional layer 520A and the substrate 510.

[0221] The functional layer 520A includes insulating film 521, insulating film 518, insulating film 516, insulating film 506 and insulating film 501C, etc.
[0222] [Insulating Film 521]
[0223] The insulating film 521 includes a region sandwiched between the pixel circuitry 530 (i, j) and the display element 550 (i, j) (see reference). Figure 5 ).
[0224] For example, insulating inorganic materials, insulating organic materials, or insulating composite materials containing both inorganic and organic materials can be used in insulating film 521.
[0225] Specifically, inorganic oxide films, inorganic nitride films, inorganic oxynitride films, or laminated materials containing multiple materials selected from these materials can be used as insulating films 521.
[0226] For example, silicon oxide films, silicon nitride films, silicon oxynitride films, aluminum oxide films, or films comprising laminates of multiple materials selected from these materials can be used as insulating films 521. Silicon nitride films are dense films and have excellent ability to suppress impurity diffusion.
[0227] For example, polyester, polyolefin, polyamide, polyimide, polycarbonate, polysiloxane, or acrylic resin, or laminates or composites of multiple resins selected from the above, can be used for the insulating film 521. Alternatively, a photosensitive material can also be used. Thus, for example, the steps of various structures arising from the overlap with the insulating film 521 can be flattened by the insulating film 521.
[0228] Compared with other organic materials, polyimide has better thermal stability, insulation, toughness, low dielectric constant, low coefficient of thermal expansion, and chemical resistance. Therefore, polyimide is particularly preferred for use in insulating films such as 521.
[0229] For example, a film formed from a photosensitive material can be used for insulating film 521. Specifically, a film formed from photosensitive polyimide or photosensitive acrylic resin can be used for insulating film 521.
[0230] For example, a transparent material can be used for insulating film 521. Specifically, silicon nitride can be used for insulating film 521.
[0231] [Insulating Film 518]

[0233] For example, the material that can be used for insulating film 521 can be used for insulating film 518.
[0234] For example, materials capable of suppressing the diffusion of oxygen, hydrogen, water, alkali metals, alkaline earth metals, etc., can be used in the insulating film 518. Specifically, nitride insulating films can be used in the insulating film 518. For example, silicon nitride, silicon oxynitride, aluminum nitride, aluminum oxynitride, etc., can be used in the insulating film 518. This prevents impurities from diffusing into the semiconductor film of the transistor.
[0235] [Insulating Film 516]
[0236] The insulating film 516 includes the region sandwiched between the pixel circuitry 530 (i, j) and the insulating film 518 (see reference). Figure 4B In addition, laminated films can be used as insulating films 516.
[0237] For example, the material that can be used for insulating film 521 can be used for insulating film 516. Specifically, a film whose manufacturing method is different from that of insulating film 518 can be used for insulating film 516.

[0241] [Insulating Film 501C]
[0242] The insulating film 501C includes a region sandwiched between the pixel circuitry 530 (i, j) and the substrate 510 (see reference). Figure 4A ).
[0243] For example, materials suitable for insulating film 521 can be used in insulating film 501C. Specifically, materials containing silicon and oxygen can be used in insulating film 501C. This can suppress the diffusion of impurities into pixel circuits or display elements, etc.
[0244] [Insulating film 528]
[0245] The insulating film 528 includes a region sandwiched between the insulating film 521 and the substrate 770, and includes an opening (see reference) in the region overlapping with the display element 550 (i, j). Figure 5 An insulating film 528 formed along the outer periphery of electrode 551(i,j) prevents short circuits between electrode 551(i,j) and electrode 552.
[0246] For example, the same material that can be used for insulating film 521 can be used for insulating film 528. Specifically, a silicon oxide film, a film containing acrylic resin, or a film containing polyimide can be used for insulating film 528.
[0247] Sealant 705

[0262] Note that this embodiment can be appropriately combined with other embodiments shown in this specification.
[0263] (Implementation Method 2)
[0264] In this embodiment, a metal oxide that can be used in the semiconductor film of a transistor disclosed in one aspect of the present invention will be described. Note that when a metal oxide is used in the semiconductor film of a transistor, the metal oxide may also be referred to as an oxide semiconductor.
[0265] Oxide semiconductors are classified into single-crystal oxide semiconductors and non-single-crystal oxide semiconductors. Non-single-crystal oxide semiconductors include CAAC-OS (c-axis-aligned crystalline oxide semiconductor), polycrystalline oxide semiconductors, nc-OS (nanocrystalline oxide semiconductor), a-like OS (amorphous-like oxide semiconductor), and amorphous oxide semiconductors, among others.
[0266] Another example of a non-monocrystalline oxide semiconductor is the oxide semiconductor known as a semi-crystalline oxide semiconductor. Semi-crystalline oxide semiconductors have an intermediate structure between monocrystalline oxide semiconductors and amorphous oxide semiconductors. Compared to amorphous oxide semiconductors, semi-crystalline oxide semiconductors have a more stable structure. For example, an oxide semiconductor with a CAAC (Cloud-Aligned Composite) structure can be cited as an example of a semi-crystalline oxide semiconductor. The details of CAC are explained below.
[0267] The semiconductor film of the transistor disclosed as one aspect of the present invention can also be CAC-OS (Cloud-Aligned Composite oxide semiconductor).
[0268] The semiconductor film of the transistor disclosed in one aspect of the present invention can use the aforementioned non-single-crystal oxide semiconductor or CAC-OS. Furthermore, nc-OS or CAAC-OS is preferred as the non-single-crystal oxide semiconductor.
[0269] In one embodiment of the invention, CAC-OS is preferably used as the semiconductor film for the transistor. By using CAC-OS, the transistor can be endowed with high electrical characteristics or high reliability.
[0270] The following is a detailed description of CAC-OS.
[0271] CAC-OS or CAC-metal oxide possesses conductive properties in one part of the material and insulating properties in another, thus functioning as a semiconductor as a whole. Furthermore, when CAC-OS or CAC-metal oxide is used in the channel formation region of a transistor, the conductive function allows electrons (or holes) used as charge carriers to flow through, while the insulating function prevents electrons from flowing through. Through the complementary effects of conductive and insulating functions, CAC-OS or CAC-metal oxide can possess switching (on / off) functionality. By separating these functions within CAC-OS or CAC-metal oxide, the functionality of each component can be maximized.
[0272] Furthermore, CAC-OS or CAC-metal oxide comprises conductive and insulating regions. The conductive regions possess the aforementioned conductive function, and the insulating regions possess the aforementioned insulating function. Moreover, in the material, the conductive and insulating regions are sometimes separated at the nanoparticle level. Additionally, the conductive and insulating regions are sometimes unevenly distributed within the material. Furthermore, sometimes the conductive regions are observed to have blurred edges and be connected in a cloud-like manner.
[0273] In CAC-OS or CAC-metal oxide, conductive and insulating regions are sometimes dispersed in the material with a size of 0.5 nm or more and 10 nm or less, preferably 0.5 nm or more and 3 nm or less.
[0274] Furthermore, CAC-OS or CAC-metal oxide is composed of components with different band gaps. For example, CAC-OS or CAC-metal oxide is composed of a component with a wide gap originating from an insulating region and a component with a narrow gap originating from a conductive region. In this structure, when charge carriers flow through, they mainly flow in the component with the narrow gap. Moreover, the component with the narrow gap complements the component with the wide gap, and charge carriers flow in the component with the wide gap in conjunction with the component with the narrow gap. Therefore, when the above-mentioned CAC-OS or CAC-metal oxide is used in the channel formation region of a transistor, a high current driving force, i.e., a large on-state current and a high field-effect mobility, can be obtained in the transistor's on-state.
[0275] In other words, CAC-OS or CAC-metal oxide can also be referred to as matrix composite or metal matrix composite.
[0276] CAC-OS, for example, refers to a composition in which elements are unevenly distributed within a metal oxide, wherein the size of the material containing the unevenly distributed elements is 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or approximately. Note that below, the state in which one or more metal elements are unevenly distributed within a metal oxide and the regions containing those metal elements are mixed is also referred to as mosaic or patch-like, where the size of these regions is 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or approximately.
[0277] The metal oxide preferably contains at least indium. In particular, it preferably contains both indium and zinc. In addition, it may also contain one or more of the following: aluminum, gallium, yttrium, copper, vanadium, beryllium, boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum, lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, and magnesium.
[0278] For example, CAC-OS in In-Ga-Zn oxides (in particular, In-Ga-Zn oxides can be referred to as CAC-IGZO) refers to materials that are indium oxides (hereinafter referred to as InO). X1 (X1 is a real number greater than 0) or indium zinc oxide (hereinafter referred to as In X2 Zn Y2 O Z2 (X2, Y2, and Z2 are real numbers greater than 0) and gallium oxide (hereinafter referred to as GaO) X3 (X3 is a real number greater than 0) or gallium zinc oxide (hereinafter referred to as Ga X4 Zn Y4O Z4 (X4, Y4, and Z4 are real numbers greater than 0) etc., thus forming a mosaic pattern, and the mosaic-shaped InO X1 or In X2 Zn Y2 O Z2 The composition (hereinafter also referred to as cloud-like) is uniformly distributed in the membrane.
[0279] In other words, CAC-OS is a system with GaO X3 The region with In as the main component and X2 Zn Y2 O Z2 or InO X1 A composite metal oxide consisting of regions that are the main components mixed together. In this specification, for example, when the ratio of the number of In atoms to the number of element M atoms in the first region is greater than that in the second region, the In concentration in the first region is higher than that in the second region.
[0280] Note that IGZO is a general term, sometimes referring to compounds containing In, Ga, Zn, and O. A typical example is InGaO3 (ZnO). m1 (m1 is a natural number) or In (1+x0) Ga (1-x0) O3(ZnO) m0 (-1≤x0≤1, m0 is any number) represents a crystalline compound.
[0281] The aforementioned crystalline compounds possess single-crystal, polycrystalline, or CAAC (c-axis aligned crystal) structures. A CAAC structure is a crystalline structure in which multiple IGZO nanocrystals exhibit c-axis orientation and are connected in a non-oriented manner on the ab plane.
[0282] On the other hand, CAC-OS is related to the material composition of metal oxides. CAC-OS refers to a material composition containing In, Ga, Zn, and O, in one part of which nanoparticle-like regions with Ga as the main component are observed, and in another part, nanoparticle-like regions with In as the main component are observed to be randomly dispersed in a mosaic pattern. Therefore, in CAC-OS, the crystal structure is a secondary factor.
[0283] CAC-OS does not contain stacked structures consisting of two or more different membranes. For example, it does not contain a structure consisting of two layers: one with In as the main component and the other with Ga as the main component.
[0284] Note that sometimes GaO cannot be observed. X3 Regions with In as the main component X2 ZnY2 O Z2 or InO X1 Clear boundaries between regions that are the main components.
[0285] In the case where CAC-OS contains one or more of aluminum, yttrium, copper, vanadium, beryllium, boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum, lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, and magnesium to replace gallium, CAC-OS refers to a composition in which nanoparticle-like regions with the metal element as the main component are observed in one part, and nanoparticle-like regions with In as the main component are observed to be randomly dispersed in a mosaic pattern in another part.
[0286] CAC-OS can be formed, for example, by sputtering without intentionally heating the substrate. When forming CAC-OS by sputtering, one or more gases selected from inert gases (typically argon), oxygen gases, and nitrogen gases can be used as the film-forming gas. Furthermore, the lower the proportion of oxygen gas in the total flow rate of the film-forming gas during film formation, the better; for example, the oxygen gas flow rate ratio is set to 0% or more and less than 30%, preferably 0% or more and less than 10%.
[0287] CAC-OS has the following characteristics: when measured using the out-of-plane method (XRD) with θ / 2θ scanning, no clear peak is observed. In other words, based on the XRD analysis results, there is no orientation along the ab plane or the c-axis in the measurement region.
[0288] Furthermore, in the electron diffraction pattern of CAC-OS obtained by irradiating it with an electron beam with a diameter of 1 nm (also known as a nanobeam), a ring-shaped region of high brightness (ring region) and multiple bright spots within the ring region were observed. Therefore, based on the electron diffraction pattern, it can be concluded that the crystal structure of CAC-OS has an nc (nano-crystal) structure that is unoriented in both the planar and cross-sectional directions.
[0289] Furthermore, for example, in CAC-OS of In-Ga-Zn oxides, based on EDX surface analysis images (EDX-mapping) obtained by energy dispersive X-ray spectroscopy (EDX), it can be confirmed that: it has GaO X3 Regions with In as the main component and X2 Zn Y2 O Z2 or InO X1 A mixture of components whose main components are unevenly distributed in different regions.
[0290] CAC-OS differs in structure from IGZO compounds, which have a uniform distribution of metallic elements, and thus exhibits different properties. In other words, CAC-OS possesses properties centered around GaO. X3 Regions with In as the main component and In X2 Zn Y2 O Z2 or InO X1 The regions that are the main components are separated from each other, and the regions that are the main components of each element are mosaic-like.
[0291] Here, in In X2 Zn Y2 O Z2 or InO X1 The conductivity of regions with GaO as the main component is higher than that of regions with GaO as the main component. X3 The region is dominated by components such as In. In other words, when charge carriers flow through a region dominated by In X2 Zn Y2 O Z2 or InO X1 When In is the dominant component, it exhibits the conductivity of an oxide semiconductor. Therefore, when In... X2 Zn Y2 O Z2 or InO X1 When the region that is the main component is distributed in a cloud-like manner in an oxide semiconductor, a high field-effect mobility (μ) can be achieved.
[0292] On the other hand, with GaO X3 The insulation of regions with In as the main component is higher than that of regions with In as the main component. X2 Zn Y2 O Z2 or InO X1 The region where GaO is the main component. In other words, when GaO is used... X3 When regions with these as the main components are distributed in an oxide semiconductor, leakage current can be suppressed, thus achieving good switching operation.
[0293] Therefore, when CAC-OS is used in semiconductor devices, it is due to GaO X3 The insulation properties of In and other materials and their causes X2 Zn Y2 O Z2 or InO X1 The complementary effect of conductivity can achieve high on-state current (I) on ) and high field-effect mobility (μ).
[0294] Furthermore, semiconductor components using CAC-OS exhibit high reliability. Therefore, CAC-OS is suitable for various semiconductor devices such as displays.
[0295] This implementation method can be appropriately combined with other implementation methods.

[0319] By using the control signal SP, the operation of the drive circuit SD and the drive circuit GD can be synchronized.
[0320] Alternatively, the display panel may also include control circuitry 233. For example, control circuitry 233 mounted on a rigid substrate can be used in the display panel. Specifically, a flexible printed circuit board can be used to electrically connect control circuitry 233 mounted on a rigid substrate to a drive circuit.
[0321] Therefore, display elements can be used to display image data. As a result, novel display devices with excellent convenience or reliability can be provided. Additionally, for example, a television receiving system (see...) can be provided. Figure 11B1 ), video monitor (refer to) Figure 11B2 ) or laptop computer (see Figure 11B3 )wait.

[0325] Figure 12 This is a block diagram illustrating the structure of an input / output device according to one aspect of the present invention.
[0326] <Example of Input / Output Device Structure>
[0327] The input / output device described in this embodiment includes an input unit 240 and a display unit 230 (see reference 230). Figure 12 ).
[0328] Display Department 230
[0329] For example, the display panel 700 described in Embodiment 1 can be used in the display unit 230. Alternatively, a panel having a structure including an input unit 240 and a display unit 230 can be referred to as an input / output panel 700TP.
[0330] Example 1 of the structure of input section 240.

[0332] The detection region 241 includes the region that overlaps with pixel 702(i,j).
[0333] Therefore, objects approaching or overlapping with the display area can be detected while displaying image data on the display unit. Alternatively, a finger or similar object approaching the display unit can be used as an indicator to input position data. Or, the position data can be correlated with image data displayed on the display unit. As a result, novel input / output devices with excellent convenience and reliability can be provided.
[0334] Example 2 of the structure of input section 240.
[0335] Input unit 240 may include an oscillator circuit OSC and a detection circuit DC (see reference). Figure 12 ).
[0336] Detection Area 241

[0344] Alternatively, multiple detection elements can be combined. For example, a finger detection element and a stylus detection element can be used in combination.
[0345] Therefore, it is possible to identify the type of indicator. Alternatively, different instructions can be associated with the detection data depending on the type of indicator identified. Specifically, if it is determined that a finger is used on the indicator, the detection data can be associated with an action. Or, if it is determined that a stylus is used on the indicator, the detection data can be associated with drawing processing.

[0378] Input Section 240
[0379] The input unit 240 has the function of supplying position data P1. Various human-machine interfaces can be used with the input unit 240 (see reference). Figure 13A ).
[0380] For example, a keyboard, mouse, touch sensor, microphone, or camera can be used for the input unit 240. Alternatively, a touch sensor having an area overlapping the display unit 230 can be used. The input / output device including the display unit 230 and the touch sensor having an area overlapping the display unit 230 can be referred to as a touch panel or touchscreen.
[0381] For example, users can use their fingers touching the touch panel as indicators to make various gestures (tap, drag, slide, or pinch, etc.).
[0382] For example, the computing device 210 analyzes data such as the position or trajectory of a finger touching the touch panel. When the analysis results meet predetermined conditions, it can be said that a predetermined gesture has been supplied. Thus, the user can use this gesture to supply predetermined operation instructions that are pre-set to be associated with the predetermined gesture.
[0383] For example, users can use gestures such as moving their fingers along the touch panel to provide "scrolling commands" to change the display position of image data.
[0384] Inspection Department 250

Alternatively, the user of the data processing device can choose the display method. As a result, a novel data processing device with excellent convenience and reliability can be provided.
[0393] Note that sometimes it is not possible to clearly distinguish the above-mentioned components; a structure may also serve as another structure or contain part of another structure. For example, a touch panel with a touch sensor arranged in a manner that overlaps with the display panel can be used as both a display unit and an input unit.
[0394] Example 2 of the structure of the arithmetic unit 210.
[0395] The computing device 210 includes an artificial intelligence unit 213 (see reference). Figure 13A The Artificial Intelligence Department 213 generates control data CI based on input data II or detection data DS.
[0396] [Natural Language Processing of Input Data II]
[0397] Specifically, the Artificial Intelligence Unit 213 can perform natural language processing on the input data II to extract a feature from the input data II as a whole.

[0399] [Image processing of input data II]
[0400] Specifically, the Artificial Intelligence Unit 213 can perform image processing on the input data II to extract a feature from it. For example, the Artificial Intelligence Unit 213 can infer the year the image of the input data II was taken, whether it was indoors or outdoors, whether it was daytime or nighttime, and use these as features. Furthermore, it can infer a hue that feels empirically suitable for the feature and generate control data CI for using that hue in the display. Specifically, data specifying the color used for shading (e.g., full color, black and white, or sepia) can be used as the control data CI.
[0401] Specifically, the Artificial Intelligence Unit 213 performs image processing on the input data II to extract a portion of the image included in the input data II. For example, control data CI can be generated that displays a boundary between one portion of the extracted image and another portion of the extracted image. Specifically, control data CI can be generated that displays a rectangle surrounding the extracted portion of the image.
[0402] [Inferences drawn from the detection data DS]
[0403] Specifically, the artificial intelligence unit 213 can use the detection data DS as data IN to generate inference RI. Alternatively, it can generate control data CI based on the inference RI to make the data processing device 200 more convenient for the user.

[0412] For example, data from the storage unit 212 is obtained, including predetermined image data to be displayed upon startup, a predetermined mode for displaying the image data, and data specifying a predetermined display method for displaying the image data. Specifically, a static image or other dynamic image data can be used as the predetermined image data. Furthermore, a first mode or a second mode can be used as the predetermined mode.
[0413] [Second Step]
[0414] In the second step, interruption processing is allowed (see...) Figure 14A (S2)). Arithmetic units with interrupt handling enabled can perform interrupt handling simultaneously with main processing. Arithmetic units that resume main processing from interrupt handling can reflect the results obtained through interrupt handling back to the main processing.
[0415] When the counter is at its initial value, the arithmetic unit is interrupted. Upon recovery from the interrupt, the counter can be set to a value other than the initial value. Therefore, interrupt handling can be executed at any time after the program starts.
[0416] [Step 3]
[0417] In the third step, the image data is displayed using the predetermined mode or predetermined display method selected in the first step or the interruption process (see reference). Figure 14A (S3)). Note that the predetermined mode specifies the mode in which the data is displayed, and the predetermined display method specifies the method in which the image data is displayed. Furthermore, for example, image data V1 can be used as the data to be displayed.
[0418] For example, one method of displaying image data V1 can be associated with a first mode. Alternatively, other methods of displaying image data V1 can be associated with a second mode. Thus, the display method can be selected based on the chosen mode.
[0419] The First Model
[0420] 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 the result based on the selection signal can be associated with the first mode.
[0421] For example, by supplying a selection signal at a frequency of 30 Hz or higher, preferably 60 Hz or higher, dynamic images can be displayed smoothly.
[0422] For example, by updating the image at a frequency of 30Hz or higher, preferably 60Hz or higher, the image can be displayed smoothly on the data processing device 200 during user operation.
[0423] The Second Mode
[0424] Specifically, the method of supplying a selection signal to a scan line at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than 1 time / min, and displaying the result based on the selection signal can be associated with the second mode.
[0425] By supplying a selection signal at a frequency below 30Hz, preferably below 1Hz, and more preferably below 1 time per minute, flicker-suppressed display can be achieved. Furthermore, power consumption can be reduced.
[0426] For example, when the data processing device 200 is used in a clock, the display can be updated at a frequency of once per second or once per minute.
[0427] Here, for example, when using a light-emitting element (LED) as a display element, the LED can emit light in a pulsed manner to display image data. Specifically, the organic EL element can emit light in a pulsed manner and utilize the afterglow for display. Because organic EL elements have excellent frequency characteristics, the driving time of the LED can sometimes be shortened, thereby reducing power consumption. Alternatively, because the heat generation of the LED is suppressed, the degradation of the LED can sometimes be mitigated.
[0428] [Fourth Step]
[0429] In the fourth step, if a supply end instruction is received, the process proceeds to the fifth step; otherwise, it proceeds to the third step (see [reference]). Figure 14A (S4)).
[0430] For example, it can be determined based on the end instruction supplied during interrupt handling.
[0431] [Step 5]
[0432] End the work in step five (see reference). Figure 14B (S5)).
[0433] Interruption Handling
[0434] Interrupt handling includes steps six through eight as follows (see reference). Figure 14B ).
[0435] [Step Six]
[0436] In the sixth step, for example, the illuminance of the operating environment of the data processing device 200 is detected using the detection unit 250 (see reference). Figure 14B (S6) Alternatively, the color temperature or chromaticity of ambient light can be detected instead of the ambient illuminance.
[0437] [Seventh Step]
[0438] In the seventh step, the display method is determined based on the detected illuminance data (see [reference]). Figure 14B (S7)). For example, the display brightness can be set to be neither too dark nor too bright.
[0439] When the color temperature or chromaticity of the ambient light is detected in step six, the display color can also be adjusted.
[0440] [Step 8]
[0441] In step eight, the interrupt handling is terminated (see...). Figures 15A to 15C (S8)).
[0442] <Example 3 of the structure of a data processing device.>
[0443] Reference Figure 15A Other structures of the data processing apparatus according to one aspect of the present invention will be described.
[0444] Figure 15A This is a flowchart illustrating one aspect of the present invention. Figure 14B It is an explanation and Figure 14B The flowcharts shown illustrate different interrupt handling procedures.
[0445] Example 3 of the structure of a data processing device and reference Figure 15A The difference in the interrupt handling described herein lies in that the interrupt handling includes a step of changing the mode based on a predetermined event being supplied. The differences will be explained in detail here, while the parts that can use the same structure as described above will refer to the above description.
[0446] Interruption Handling
[0447] Interrupt handling includes steps six through eight as follows (see reference). Figure 15A ).
[0448] [Step Six]
[0449] In step six, if a predetermined event is supplied, proceed to step seven; if no predetermined event is supplied, proceed to step eight (see reference). Figure 15A (U6)). For example, whether a predetermined event is supplied within a predetermined period can be used as a condition. Specifically, the predetermined period can be longer than 0 seconds and less than 5 seconds, less than 1 second, or less than 0.5 seconds, preferably less than 0.1 seconds.
[0450] [Seventh Step]
[0451] In step seven, change the pattern (see...) Figure 15B (U7)). Specifically, if the first mode was previously selected, the second mode will be selected; if the second mode was previously selected, the first mode will be selected.
[0452] For example, the display mode of a portion of the display unit 230 can be changed. Specifically, the display mode of an area of the display unit 230, which has drive circuits GDA, GDB, and GDC, supplied with a selection signal by one of its drive circuits (see reference 230) can be changed. Figure 15B ).
[0453] For example, when a predetermined event is supplied to the input section 240 in the area overlapping with the area where the drive circuit GDB supplies the selection signal, the display mode of the area where the drive circuit GDB supplies the selection signal can be changed (see reference). Figure 15C and Figure 15A Specifically, the frequency of the selection signal supplied by the drive circuit GDB can be changed by using a finger or the like based on events supplied to the touch panel (e.g., "tap").
[0454] In addition, signal GCLK is the clock signal that controls the operation of drive circuit GDB, while signals PWC1 and PWC2 are pulse width control signals that control the operation of drive circuit GDB. Drive circuit GDB supplies selection signals to scan lines G1(m+1) to scan line G1(2m) according to signals GCLK, PWC1, and PWC2.
[0455] Therefore, for example, it is possible to supply a selection signal to the drive circuit GDB when the drive circuits GDA and GDC do not supply a selection signal. Alternatively, it is possible to update the display of the area where the drive circuit GDB supplies a selection signal without changing the display of the area where the drive circuits GDA and GDC supply selection signals. Alternatively, it is possible to reduce the power consumption of the drive circuit.
[0456] [Step 8]
[0457] In step eight, the interrupt handling is terminated (see...). Figure 13C(U8)). Alternatively, interruption processing can be performed repeatedly during the main processing.
[0458] Scheduled Event
[0459] For example, events such as "click" or "drag" provided by pointing devices such as mice can be used, or events such as "tap", "drag", or "swipe" provided by touch panels can be used by using fingers as indicators.
[0460] For example, parameters such as the position of the slider, sliding speed, and dragging speed indicated by the indicator can be used to supply instructions associated with predetermined events.
[0461] For example, a pre-set threshold can be compared with the data detected by the detection unit 250, and the comparison result can be used for events.
[0462] Specifically, a pressure-sensitive detector or the like that comes into contact with a button or similar device that can be pressed into the housing can be used in the detection unit 250.
[0463] Instructions related to scheduled events
[0464] For example, an end command can be associated with a pre-defined event.
[0465] For example, a "page-turning instruction" that switches displayed image data to other image data can be associated with a pre-defined event. Furthermore, the pre-defined event can be used to supply parameters such as the page-turning speed used when executing the "page-turning instruction".
[0466] For example, a "scrolling instruction" that moves the display position of a portion of an image data being displayed and displays other portions that are adjacent to that portion can be associated with a predetermined event. Furthermore, the predetermined event can be used to supply parameters such as the speed at which the display position is moved when the "scrolling instruction" is executed.
[0467] For example, instructions for setting the display method or generating image data can be associated with a predetermined event. Furthermore, parameters determining the brightness of the generated image can be associated with a predetermined event. Additionally, parameters determining the brightness of the generated image can be based on the brightness of the environment detected by the detection unit 250.
[0468] For example, instructions such as obtaining data transmitted using the push service via the communication unit 290 can be associated with a predetermined event.
[0469] Furthermore, location data detected by the detection unit 250 can be used to determine eligibility for data acquisition. Specifically, when the location is in a designated classroom, school, conference room, business, or residence, eligibility for data acquisition can be determined. Thus, for example, teaching materials transmitted in classrooms at schools or universities can be received, and the data processing device 200 can be used as a textbook, etc. (see reference). Figures 16A to 16E Alternatively, it can receive data transmitted to meeting rooms in companies, etc., and use it as meeting materials.
[0470] Note that this embodiment can be appropriately combined with other embodiments shown in this specification.

[0502] Note that this embodiment can be appropriately combined with other embodiments shown in this specification.
[0503] For example, in this specification, when it is explicitly stated as "X and Y are connected," the situations disclosed in this specification include: X and Y being electrically connected; X and Y being functionally connected; and X and Y being directly connected. Therefore, connection relationships other than those shown in the drawings or text are also disclosed in the drawings or text, not limited to the predetermined connection relationships shown in the drawings or text.
[0504] Here, X and Y are objects (e.g., devices, components, circuits, wiring, electrodes, terminals, conductive films, layers, etc.).
[0505] As an example of the case where X and Y are directly connected, we can cite the case where there is no component (e.g., switch, transistor, capacitor, inductor, resistor, diode, display element, light-emitting element, and load) connecting X and Y, and the case where X and Y are connected without any component (e.g., switch, transistor, capacitor, inductor, resistor, diode, display element, light-emitting element, and load) connecting X and Y.
[0506] As an example of an X and Y electrical connection, more than one component capable of electrically connecting X and Y (e.g., switch, transistor, capacitor, inductor, resistor, diode, display element, light-emitting element, load, etc.) can be connected between X and Y. Furthermore, the switch has the function of controlling whether conduction is on or off. In other words, the switch has the function of controlling whether current flows by controlling whether it is in a conducting state (on state) or a non-conducting state (off state). Alternatively, the switch has the function of selecting and switching the current path. Additionally, X and Y electrical connections also include cases where X and Y are directly connected.
[0507] As an example of a functional connection between X and Y, more than one circuit capable of functionally connecting X and Y can be connected between them (e.g., logic circuits (inverters, NAND circuits, NOR circuits, etc.), signal conversion circuits (DA converters, AD converters, gamma correction circuits, etc.), potential level conversion circuits (power supply circuits (boost circuits, buck circuits, etc.), level converter circuits that change the potential level of a signal, etc.), voltage sources, current sources, switching circuits, amplification circuits (circuits that can increase signal amplitude or current, operational amplifiers, differential amplifiers, source follower circuits, buffer circuits, etc.), signal generation circuits, storage circuits, control circuits, etc.). Note that, for example, even if other circuits are sandwiched between X and Y, when the signal output from X is transmitted to Y, it can be said that X and Y are functionally connected. Furthermore, the functional connection of X and Y includes both direct connection and electrical connection.
[0508] Furthermore, when explicitly stated as "X and Y are electrically connected," the situations disclosed in this specification, etc., include: X and Y being electrically connected (in other words, X and Y being connected with other components or other circuits in between); X and Y being functionally connected (in other words, X and Y being functionally connected with other circuits in between); and X and Y being directly connected (in other words, X and Y being connected without other components or other circuits in between). In other words, when explicitly stated as "electrically connected," it means that the content disclosed in this specification, etc., includes the same content as in the cases where only "connected" is explicitly stated.
[0509] Note that, for example, the transistor's source (or first terminal, etc.) is electrically connected to X via Z1 (or not via Z1), and the transistor's drain (or second terminal, etc.) is electrically connected to Y via Z2 (or not via Z2). Additionally, the transistor's source (or first terminal, etc.) is directly connected to a portion of Z1, and another portion of Z1 is directly connected to X, while the transistor's drain (or second terminal, etc.) is directly connected to a portion of Z2, and another portion of Z2 is directly connected to Y. These cases can be represented as follows.
[0510] For example, it can be represented as "X, Y, the source (or first terminal, etc.) of the transistor, and the 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." Alternatively, it can be represented 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 sequence." Or, it can be represented 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 arranged to be interconnected in sequence." By specifying the connection order in the circuit structure using the same expression as this example, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor can be distinguished, thus determining the scope of the technology.
[0511] Alternatively, as another way of expressing it, it can be expressed as follows: "The source (or first terminal, etc.) of the transistor is electrically connected to X at least through a first connection path, wherein the first connection path does not have a second connection path, wherein the second connection path is a path between the source (or first terminal, etc.) and the drain (or second terminal, etc.) of the transistor, wherein the first connection path is a path through Z1, and the drain (or second terminal, etc.) of the transistor is electrically connected to Y at least through a third connection path, wherein the third connection path does not have the second connection path, wherein the third connection path is a path through Z2." Or, it can also be expressed as: "The source (or first terminal, etc.) of the transistor is electrically connected to X at least through Z1 on a first connection path, wherein the first connection path does not have a second connection path, wherein 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 at least through Z2 on a third connection path, wherein 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 through at least a first electrical path, the first electrical path not having a second electrical path, the second electrical path being 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 through at least a third electrical path, the third electrical path not having a fourth electrical path, the fourth electrical path being an electrical path from the drain (or second terminal, etc.) of the transistor to the source (or first terminal, etc.) of the transistor." By specifying the connection paths in the circuit structure using the same expressions as these examples, the source (or first terminal, etc.) and drain (or second terminal, etc.) of the transistor can be distinguished to determine the scope of the technology.
[0512] Note that this method of expression is an example and is not limited to the methods described above. Here, X, Y, Z1, and Z2 refer to objects (e.g., devices, components, circuits, wiring, electrodes, terminals, conductive films and layers, etc.).
[0513] Furthermore, even when individual components are shown as electrically connected to each other in a circuit diagram, sometimes one component functions as multiple components. For example, when a portion of a wiring is used as an electrode, a conductive film functions as both a wiring and an electrode component. Therefore, the scope of "electrical connection" in this specification also includes such cases where a conductive film functions as multiple components.
