[0059] In this specification, when substance A is dispersed in a matrix made of another substance B, substance B constituting the matrix is ​​called a host material, and substance A dispersed in the matrix is ​​called a guest material. Note that substance A and substance B may each be a single substance, or a mixture of two or more substances.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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

Or, a novel information processing device with excellent convenience or reliability can be provided.

[0068] Note that the description of these effects does not preclude the existence of other effects. Note that one embodiment of the present invention does not necessarily have all of these effects. 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]

[0070] One embodiment of the present invention is a display panel having a display area. The display area includes a first pixel, and the first pixel includes a first display element, a first color conversion layer, and a first absorption layer. The first display element emits a first light, and the first absorption layer overlaps with the first display element, and the first absorption layer absorbs the first light. The first color conversion layer is sandwiched between the first absorption layer and the first display element, and the first color conversion layer converts the first light into a second light, and the second light has a spectrum containing a higher proportion of light with a longer wavelength than the first light.

[0071] This makes it possible to convert the first light emitted by the first display element into the second light. Alternatively, it is possible to weaken the first light contained in the external light before it reaches the first color conversion layer. Alternatively, it is possible to suppress the phenomenon in which the first light contained in the external light is converted into the second light. Alternatively, it is possible to suppress the phenomenon in which the display of black is impaired by the external light. Alternatively, it is possible to display with high contrast. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

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

[0073] (Embodiment 1) In this embodiment, a structure of a display panel according to one embodiment of the present invention will be described with reference to FIGS.

[0074] FIG 1 is a diagram illustrating a configuration of a display panel of one embodiment of the present invention. FIG 1(A) is a schematic diagram illustrating a pixel configuration of a display panel of one embodiment of the present invention, and FIG 1(B) is a schematic diagram illustrating a configuration different from that of FIG 1(A). FIG 1(C) is a diagram illustrating an emission spectrum of a display panel of one embodiment of the present invention and an absorption spectrum of an absorption layer. Note that the emission spectrum is indicated by a solid line, and the absorption spectrum is indicated by a dashed line.

[0075] 2 is a graph showing an emission spectrum of a display panel and an absorption spectrum of an absorption layer according to one embodiment of the present invention, in which a solid line indicates the emission spectrum and a dashed line indicates the absorption spectrum.

[0076] 3A and 3B are diagrams illustrating a structure of a display panel according to one embodiment of the present invention, in which Fig. 3A is a top view of a display panel according to one embodiment of the present invention, and Fig. 3B is a part of Fig. 3A.

[0077] 4A and 4B are diagrams illustrating a configuration of a display panel according to one embodiment of the present invention, in which (A) is a cross-sectional view taken along lines X1-X2, X3-X4, and X9-X10 in FIG. 3A and a pixel, and (B) is a circuit diagram illustrating a configuration of a pixel circuit 530(i,j).

[0078] 5A and 5B are diagrams illustrating a structure of a display panel according to one embodiment of the present invention, in which Fig. 5A is a cross-sectional view of a pixel 702(i,j) in Fig. 3A, and Fig. 5B is a cross-sectional view illustrating a part of Fig. 5A.

[0079] 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.

[0080] <Configuration Example 1 of Display Panel 700> A display panel 700 described in this embodiment includes a display region 231 and a functional layer 520 (see FIGS. 3A and 4A). The display region 231 includes pixels 702(i,j) (see FIG. 3B).

[0081] <<Configuration example 1 of pixel 702(i,j)>> A pixel 702(i,j) includes a display element 550(i,j), a color conversion layer CC(j) and an absorption layer CF(j) (see FIGS. 1(A) and 1(B)).

[0082] Configuration example 1 of display element 550(i,j) Display element 550(i,j) emits light h1. For example, blue light or ultraviolet light can be used as light h1. Also, a light emitting element that emits light h1 can be used as display element 550(i,j). Specifically, an organic EL element or the like can be used as display element 550(i,j).

[0083] For example, a tandem-type light-emitting element having a configuration including a plurality of light-emitting units and an intermediate layer can be used for the display element 550(i,j). Specifically, a configuration including two or more light-emitting units, each including a material that emits blue light and another material that also emits blue light, can be used for the display element 550(i,j). By stacking light-emitting units including materials that emit light of the same color with an intermediate layer sandwiched between them, the amount of light emitted can be increased without increasing the current density. This can improve the reliability of the display panel.

[0084] Example 1 of the structure of the absorbing layer CF(j) The absorbing layer CF(j) overlaps with the display element 550(i,j), and the absorbing layer CF(j) absorbs light h1 (see FIG. 1(A), FIG. 1(C), or FIG. 2(A)).

[0085] For example, a material that absorbs light h1 can be used for the absorption layer CF(j). Or, a material that absorbs blue light h1 or ultraviolet light can be used for the absorption layer CF(j). For example, a sharp cut filter that transmits yellow light can be used for the absorption layer CF(j) (see FIG. 1(C)). Or, a band pass filter that transmits green light can be used for the absorption layer CF(j) (see FIG. 2(A)). This allows the absorption layer CF(j) to absorb the light h1 emitted by the display element 550(i,j). Or, the light h1 contained in external light can be absorbed. Or, the intensity of the light h1 contained in external light can be weakened before it reaches the color conversion layer CC(j).

[0086] Example 1 of the color conversion layer CC(j) Color conversion layer CC(j) is sandwiched between absorption layer CF(j) and display element 550(i,j). Color conversion layer CC(j) also converts light h1 into light h2.

[0087] For example, a phosphor can be used in the color conversion layer CC(j). Specifically, quantum dots can be used in the color conversion layer CC(j).

[0088] Compared to light h1, light h2 has a spectrum that contains a high proportion of light with longer wavelengths (see FIG. 1(C)). For example, blue light can be used as light h1, and green light can be used as light h2. Specifically, quantum dots that convert blue light h1 to green light h2 can be used in the color conversion layer CC(j). This makes it possible to efficiently convert light h1 into light h2. Alternatively, light h1 can be converted into light h2 with a narrow half-width spectrum. Alternatively, vivid colors can be displayed.

[0089] This makes it possible to convert light h1 emitted by display element 550(i,j) into light h2. Alternatively, it is possible to weaken light h1 contained in external light before it reaches color conversion layer CC(j). Alternatively, it is possible to suppress the phenomenon in which light h1 contained in external light is converted into light h2. Alternatively, it is possible to suppress the phenomenon in which a black display is impaired by external light. Alternatively, it is possible to provide a display with high contrast. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0090] Example 2 of the structure of the absorbing layer CF(j) Furthermore, for example, the absorbing layer CF(j) absorbs light h1 and light h3. Note that the light h3 has a spectrum that includes a high proportion of light with long wavelengths compared to the light h2 (see FIGS. 1(A) and 2(A)).

[0091] Specifically, green light h2 can be used, and a color filter that transmits the green light h2 can be used in the absorption layer CF(j). For example, a bandpass filter that transmits green light can be used in the absorption layer CF(j) (see FIG. 2(A)). This allows the absorption layer CF(j) to absorb, for example, blue light h1 and red light h3.

[0092] This makes it possible to absorb the light h1 and light h3 contained in external light. Alternatively, it is possible to suppress the phenomenon in which the black display is impaired by external light. Alternatively, it is possible to display with high contrast. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0093] Example 2 of the color conversion layer CC(j) Also, for example, color conversion layer CC(j) converts light h1 into light h2 and light h3 (see FIGS. 1(B) and 2(A)).

[0094] Specifically, blue light h1 can be converted into green light h2 and red light h3 using phosphors. For example, quantum dots that convert blue light h1 into green light h2 and quantum dots that convert blue light h1 into red light h3 can be mixed and used in the color conversion layer CC(j).

[0095] This makes it possible to convert light h1 emitted by display element 550(i,j) into light h2 and light h3. Alternatively, it is possible to absorb the converted light h3. Alternatively, it is possible to suppress the phenomenon in which light h1 contained in external light is converted into light h2 and light h3. Alternatively, it is possible to suppress the phenomenon in which a vivid display using light h2 is impaired by light h3. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0096] <Configuration Example 2 of Display Panel 700> In addition, in the display panel described in this embodiment mode, the display area 231 includes a pixel 702(i, j+1) (see FIG. 3B).

[0097] Example of the configuration of pixel 702(i,j+1) The pixel 702(i,j+1) includes a display element 550(i,j+1), a color conversion layer CC(j+1) and an absorption layer CF(j+1) (see FIGS. 1(A) and 1(B)).

[0098] Example of the configuration of display element 550(i,j+1) Display element 550(i,j+1) emits light h1. For example, blue light or ultraviolet light may be used as light h1, and a light emitting element that emits light h1 may be used for display element 550(i,j+1). Specifically, an organic EL element or the like may be used for display element 550(i,j+1). For example, the same configuration as that used for display element 550(i,j) may be used for display element 550(i,j+1).

[0099] 《Configuration example 1 of absorbing layer CF(j+1)》 The absorbing layer CF(j+1) overlaps with the display element 550(i,j+1), and the absorbing layer CF(j+1) absorbs light h1 (see FIG. 1(A), FIG. 1(C), or FIG. 2(B)).

[0100] For example, a material that absorbs light h1 can be used for the absorption layer CF(j+1). A material that absorbs blue light or ultraviolet light can be used for the absorption layer CF(j+1). For example, a sharp cut filter that transmits yellow light can be used for the absorption layer CF(j) (see FIG. 1(C)). Or, a sharp cut filter that transmits red light can be used for the absorption layer CF(j+1) (see FIG. 2(B)). This allows the absorption layer CF(j+1) to absorb the light h1 emitted by the display element 550(i,j+1). Or, the light h1 contained in external light can be absorbed. Or, the intensity of the light h1 contained in external light can be weakened before it reaches the color conversion layer CC(j+1).

[0101] Example 1 of the color conversion layer CC(j+1) Color conversion layer CC(j+1) is sandwiched between absorption layer CF(j+1) and display element 550(i,j+1), and color conversion layer CC(j+1) converts light h1 into light h3.

[0102] For example, a phosphor can be used in the color conversion layer CC(j+1). Specifically, quantum dots can be used in the color conversion layer CC(j+1). For example, quantum dots that convert blue light h1 into red light h3 can be used in the color conversion layer CC(j+1).

[0103] This makes it possible to convert the light h1 emitted by the display element 550(i,j+1) into light h3. Alternatively, it is possible to weaken the light h1 contained in the external light before it reaches the color conversion layer CC(j+1). Alternatively, it is possible to suppress the phenomenon in which the light h1 contained in the external light is converted into light h3. Alternatively, it is possible to suppress the phenomenon in which the display of black is impaired by the external light. Alternatively, it is possible to display with high contrast. Alternatively, it is possible to form the display element 550(i,j+1) in the same process as the process in which the display element 550(i,j) is formed. As a result, it is possible to provide a novel display panel that is excellent in convenience and reliability.

[0104] 《Configuration example 2 of absorbing layer CF(j+1)》 Furthermore, for example, the absorbing layer CF(j+1) absorbs the light h1 and the light h2 (see FIGS. 1(A) and 2(B)).

[0105] Specifically, red light h3 is used, and a color filter that transmits the red light h3 can be used in the absorption layer CF(j+1). For example, a bandpass filter that transmits red light can be used in the absorption layer CF(j+1) (see FIG. 2(B)). This allows the absorption layer CF(j+1) to absorb, for example, blue light h1 and green light h2.

[0106] This makes it possible to absorb the light h1 and the light h2. Alternatively, it is possible to suppress the phenomenon in which the black display is impaired by external light. Alternatively, it is possible to display with high contrast. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0107] Example 2 of the color conversion layer CC(j+1) Also, for example, color conversion layer CC(j+1) converts light h1 into light h2 and light h3 (see FIGS. 1(B) and 2(B)).

[0108] Specifically, blue light h1 can be converted into green light h2 and red light h3 using phosphors. For example, quantum dots that convert blue light h1 into green light h2 and quantum dots that convert blue light h1 into red light h3 can be mixed and used in the color conversion layer CC(j+1).

[0109] This makes it possible to convert the light h1 emitted by the display element 550(i,j+1) into light h2 and light h3. Alternatively, it is possible to absorb the converted light h2. Alternatively, it is possible to suppress the phenomenon in which the light h1 contained in the external light is converted into light h2 and light h3. Alternatively, it is possible to suppress the phenomenon in which a vivid display using light h3 is impaired by light h2. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0110] <Configuration Example 3 of Display Panel 700> In addition, in the display panel described in this embodiment mode, the display area 231 includes a pixel 702(i, j+2) (see FIG. 3C).

[0111] <<Configuration example 1 of pixel 702(i,j+2)>> Pixel 702(i,j+2) includes display element 550(i,j+2) (see FIGS. 1(A) and 1(B)).

[0112] Example of the configuration of display element 550(i,j+2) Display element 550(i,j+2) emits light h1. For example, blue light or ultraviolet light may be used as light h1, and a light-emitting element that emits light h1 may be used for display element 550(i,j+2). Specifically, an organic EL element or the like may be used for display element 550(i,j+2). For example, the same configuration as that used for display element 550(i,j) may be used for display element 550(i,j+2).

[0113] This allows display using light h1, light h2, and light h3. Alternatively, full-color display can be achieved using only a display element that emits light h1. Alternatively, display element 550(i,j+1) and display element 550(i,j+2) can be formed in the same process as that for forming display element 550(i,j). As a result, a novel display panel with excellent convenience and reliability can be provided.

[0114] <Configuration Example 4 of Display Panel 700> In addition, in the display panel described in this embodiment, the display area 231 includes a pixel 702(i,j), a pixel 702(i,j+1), and a pixel 702(i,j+2) (see FIG. 3C).

[0115] <<Configuration example 2 of pixel 702(i,j+2)>> Pixel 702(i,j+2) includes a color conversion layer CC(j+2) and an absorption layer CF(j+2) (see FIG. 1(B)).

[0116] Example of the structure of the absorbing layer CF(j+2) The absorbing layer CF(j+2) overlaps with the display element 550(i,j+2), and the absorbing layer CF(j+2) absorbs light h2 and light h3 (see FIG. 2(C)).

[0117] Specifically, a color filter that transmits blue light can be used for the absorption layer CF(j+2). For example, a bandpass filter that transmits blue light can be used for the absorption layer CF(j+2) (see FIG. 2(C)). This allows the absorption layer CF(j+2) to absorb, for example, green light h2 and red light h3.

[0118] Example 3 of the color conversion layer CC(j) The color conversion layer CC(j) converts the light h1 into light h2, light h3, and light h4 (see FIG. 1(B)). In other words, it converts the light h1 into white light.

[0119] For example, a phosphor can be used in the color conversion layer CC(j). Specifically, quantum dots that convert light h1 to light h2, quantum dots that convert light h1 to light h3, and quantum dots that convert light h1 to light h4 can be used in the color conversion layer CC(j). Note that the color conversion layer CC(j) may transmit a part of the light h1.

[0120] Example 3 of the color conversion layer CC(j+1) Color conversion layer CC(j+1) converts light h1 into light h2, light h3, and light h4. For example, the same configuration as color conversion layer CC(j) can be used for color conversion layer CC(j+1).

[0121] Example of the color conversion layer CC(j+2) Color conversion layer CC(j+2) is sandwiched between absorption layer CF(j+2) and display element 550(i,j+2).

[0122] Color conversion layer CC(j+2) converts light h1 into light h2, light h3, and light h4. For example, the same configuration as color conversion layer CC(j) can be used for color conversion layer CC(j+1).

[0123] Compared to the light h2, the light h4 has a spectrum that contains a higher proportion of light with shorter wavelengths (see FIG. 1(C)). For example, blue light can be used for the light h1, green light for the light h2, and blue light for the light h4.

[0124] This makes it possible to convert the light h1 emitted by the display element 550(i,j+2) into light h2, light h3, and light h4. Or, it is possible to absorb the converted light h2 and light h3. Or, it is possible to suppress the phenomenon in which a vivid display using light h4 is impaired by light h2 and light h3. Or, it is possible to use the same configuration as that of the color conversion layer CC(j) for the color conversion layer CC(j+1) and the color conversion layer CC(j+2). As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0125] <Configuration Example 5 of Display Panel 700> In the display panel described in this embodiment, the pixel 702(i,j) emits light of a color whose chromaticity x in the CIE1931 chromaticity coordinates is 0.130 or more and 0.250 or less, and whose chromaticity y is 0.710 or more and 0.810 or less.

[0126] Furthermore, pixel 702(i,j+1) emits light of a color whose chromaticity x in the CIE1931 chromaticity coordinates is greater than 0.680 and less than or equal to 0.720, and whose chromaticity y is greater than or equal to 0.260 and less than or equal to 0.320.

[0127] Furthermore, pixel 702(i,j+2) emits light of a color having a chromaticity x of 0.120 or more and 0.170 or less, and a chromaticity y of 0.020 or more and less than 0.060 in the CIE1931 chromaticity coordinates.

[0128] In addition, pixels 702(i,j), 702(i,j+1), and 702(i,j+2) are provided so that the area ratio to the BT.2020 color gamut in the CIE chromaticity diagram (x,y) is 80% or more, or the coverage rate to the color gamut is 75% or more. Preferably, the area ratio is 90% or more, or the coverage rate is 85% or more.

[0129] This makes it possible to display vivid images. This makes it possible to display an extremely wide color gamut that meets the color gamut of the international standard Recommendation ITU-R BT.2020-2. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0130] <<Configuration example 2 of pixel 702(i,j)>> Pixel 702(i,j) includes a display element 550(i,j) and a pixel circuit 530(i,j).

[0131] Display element 550(i,j) is electrically connected to pixel circuit 530(i,j).

[0132] Example of configuration of functional layer 520 The functional layer 520 includes a pixel circuit 530(i,j). The functional layer 520 also includes an opening 591A. For example, in the opening 591A, the pixel circuit 530(i,j) is electrically connected to a display element 550(i,j) (see FIG. 4(A)).

[0133] Configuration example 1 of pixel circuit 530(i,j) The pixel circuit 530(i,j) is electrically connected to a scanning line G21(i) and a signal line S21(j) (see FIG. 4(B)).

[0134] For example, a switch, a transistor, a diode, a resistor, an inductor, a capacitor, or the like can be used in the pixel circuit 530(i,j). Specifically, a transistor can be used as a switch.

[0135] Configuration example 2 of pixel circuit 530(i,j) For example, a switch SW21, a transistor M, and a capacitive element C21 can be used in a pixel circuit 530(i,j).

[0136] The pixel circuit 530(i,j) includes a transistor M, a capacitance element C21, a switch SW21, and a node N1(i,j).

[0140] The display element 550(i,j) displays based on the potential VN of the node N1(i,j).

[0141] Configuration example 2 of pixel circuit 530(i,j) The pixel circuit 530(i,j) includes a transistor M, a capacitance element C21, a switch SW21, a node N1(i,j), a capacitance element C22, and a switch SW22.

[0142] The transistor M has a first electrode electrically connected to the conductive film ANO and a second electrode electrically connected to the display element 550(i,j).

[0143] The capacitive element C21 has a first electrode electrically connected to the gate electrode of the transistor M, and a second electrode electrically connected to the conductive film ANO.

[0145] The capacitive element C22 has a first terminal electrically connected to the node N1(i,j), and the capacitive element C22 has a second terminal electrically connected to the switch SW22.

[0146] The switch SW22 has a first terminal to which a second signal is supplied, and has a function of switching between a conductive state and a non-conductive state based on the second signal.

[0147] In addition, switch SW22 is in a conductive state when switch SW21 changes from a conductive state to a non-conductive state, switch SW22 has a function of changing from a non-conductive state to a conductive state when switch SW21 is in a non-conductive state, and switch SW22 has a function of changing from a conductive state to a non-conductive state when switch SW21 is in a non-conductive state.

[0148] The display element 550(i,j) displays based on the potential VN of the node N1(i,j).

[0149] As a result, the potential of the node N1(i,j) can be controlled using the switch SW21 and the switch SW22. Alternatively, the potential of the node N1(i,j) can be controlled using the switch SW21, and the potential of the node N1(i,j) can be changed using the switch SW22. Alternatively, the changing potential can be supplied to the display element 550(i,j). Alternatively, a display can be made based on the changing potential. Alternatively, the display of the display element 550(i,j) can be changed. Alternatively, the operation of the display element 550(i,j) can be emphasized. Alternatively, the response of the display element 550(i,j) can be made faster. As a result, a novel display panel with excellent convenience or reliability can be provided.

[0150] <<Transistor configuration example 1.>> For example, bottom-gate transistors or top-gate transistors can be used in the pixel circuit 530(i,j).

[0151] The transistor includes a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see FIG. 5B).

[0152] The semiconductor film 508 includes a region 508A electrically connected to the conductive film 512A and a region 508B electrically connected to the conductive film 512B. The semiconductor film 508 includes a region 508C between the region 508A and the region 508B.

[0153] The conductive film 504 has a region overlapping with the region 508C, and has a function of a gate electrode.

[0154] The insulating film 506 has a region sandwiched between the semiconductor film 508 and the conductive film 504. The insulating film 506 functions as a gate insulating film.

[0155] The conductive film 512A has either a source electrode function or a drain electrode function, and the conductive film 512B has the other of the source electrode function or the drain electrode function.

[0156] The conductive film 524 can be used for a transistor. The conductive film 524 has a region where the semiconductor film 508 is sandwiched between the conductive film 504 and the conductive film 524. The conductive film 524 has a function of a second gate electrode. The conductive film 524 can be electrically connected to the conductive film 504, for example. Note that the conductive film 524 can be used for the scan line G21(i).

[0157] Note that a semiconductor film used for a transistor in a driver circuit can be formed in a process of forming a semiconductor film used for a transistor in a pixel circuit.

[0158] Configuration example 1 of semiconductor film 508 For example, a semiconductor containing a Group 14 element can be used for the semiconductor film 508. Specifically, a semiconductor containing silicon can be used for the semiconductor film 508.

[0159] [Hydrogenated amorphous silicon] For example, hydrogenated amorphous silicon can be used for the semiconductor film 508. Alternatively, microcrystalline silicon or the like can be used for the semiconductor film 508. This makes it possible to provide a display panel with less display unevenness than a display panel using polysilicon for the semiconductor film 508. Alternatively, it is easy to increase the size of the display panel.

[0160] [Polysilicon] For example, polysilicon can be used for the semiconductor film 508. This allows the field effect mobility of the transistor to be higher than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, the driving capability can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, the aperture ratio of a pixel can be improved than that of a transistor using hydrogenated amorphous silicon for the semiconductor film 508.

[0161] Alternatively, for example, the reliability of the transistor can be improved as compared to a transistor in which hydrogenated amorphous silicon is used for the semiconductor film 508 .

[0162] Alternatively, the temperature required to manufacture the transistor can be made lower than that of a transistor using single crystal silicon, for example.

[0163] 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.

[0164] [Single crystal silicon] For example, single crystal silicon can be used for the semiconductor film. This allows the resolution to be increased as compared to a display panel using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, a display panel with less display unevenness as compared to a display panel using polysilicon for the semiconductor film 508 can be provided. Alternatively, for example, smart glasses or a head mounted display can be provided.

[0165] Configuration example 2 of semiconductor film 508 For example, metal oxide can be used for the semiconductor film 508. This allows the pixel circuit to hold an image signal for a longer period of time compared to a pixel circuit using a transistor with amorphous silicon 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, the fatigue accumulated by the user of the information processing device can be reduced. Also, the power consumption associated with driving can be reduced.

[0166] For example, a transistor including an oxide semiconductor can be used. Specifically, an oxide semiconductor including indium or an oxide semiconductor including indium, gallium, and zinc can be used for a semiconductor film.

[0167] For example, a transistor whose leakage current in an off state is smaller than that of a transistor whose semiconductor film is made of amorphous silicon can be used. Specifically, a transistor whose semiconductor film is made of an oxide semiconductor can be used.

[0168] For example, a 25 nm thick film containing indium, gallium and zinc can be used for the semiconductor film 508 .

[0169] For example, a conductive film in which a 10-nm-thick film containing tantalum and nitrogen and a 300-nm-thick film containing copper are stacked can be used as the conductive film 504. Note that the film containing copper has a region in which the film containing tantalum and nitrogen is sandwiched between the insulating film 506 and the copper-containing film.

[0170] For example, a stacked film in which a 400-nm-thick film containing silicon and nitrogen and a 200-nm-thick film containing silicon, oxygen, and nitrogen are stacked can be used as the insulating film 506. Note that the film containing silicon and nitrogen has a region in which the film containing silicon, oxygen, and nitrogen is sandwiched between the semiconductor film 508 and the film containing silicon and nitrogen.

[0171] For example, a conductive film in which a 50-nm-thick film containing tungsten, a 400-nm-thick film containing aluminum, and a 100-nm-thick film containing titanium are stacked in this order can be used as the conductive film 512A or the conductive film 512B. Note that the film containing tungsten has a region in contact with the semiconductor film 508.

[0172] Incidentally, for example, a manufacturing line for bottom-gate transistors using amorphous silicon as a semiconductor can be easily modified to a manufacturing line for bottom-gate transistors using an oxide semiconductor as a semiconductor. Also, for example, a manufacturing line for top-gate transistors using polysilicon as a semiconductor can be easily modified to a manufacturing line for top-gate transistors using an oxide semiconductor as a semiconductor. Either modification can effectively utilize the existing manufacturing line.

[0173] This makes it possible to suppress flickering. Or, it makes it possible to reduce power consumption. Or, it makes it possible to display fast-moving videos smoothly. Or, it makes it possible to display photographs and the like with a rich range of gradations. As a result, it is possible to provide a novel display panel that is highly convenient and reliable.

[0174] Configuration example 3 of semiconductor film 508 For example, a compound semiconductor can be used as the semiconductor of a transistor, specifically, a semiconductor containing gallium arsenide can be used.

[0175] 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.

[0185] For example, a silicon oxide film, a silicon nitride film, a silicon oxynitride film, an aluminum oxide film, or a film containing a laminated material selected from these can be used for the insulating film 521. Note that a silicon nitride film is a dense film and has an excellent function of suppressing diffusion of impurities.

[0186] For example, polyester, polyolefin, polyamide, polyimide, polycarbonate, polysiloxane, acrylic resin, or a laminated material or composite material of a plurality of resins selected from these can be used for the insulating film 521. Alternatively, the insulating film 521 may be formed using a photosensitive material. Thus, for example, the insulating film 521 can flatten steps resulting from various structures overlapping with the insulating film 521.

[0187] Polyimide has superior properties compared to other organic materials in terms of thermal stability, insulating properties, toughness, low dielectric constant, low coefficient of thermal expansion, chemical resistance, etc. Therefore, polyimide can be suitably used for the insulating film 521, etc.

[0188] For example, a film formed using a photosensitive material can be used for the insulating film 521. Specifically, a film formed using a photosensitive polyimide, a photosensitive acrylic resin, or the like can be used for the insulating film 521.

[0207] For example, the terminal 519B and the flexible printed circuit board FPC1 can be electrically connected to each other using the conductive material ACF1. Specifically, the terminal 519B and the flexible printed circuit board FPC1 can be electrically connected to each other using the conductive material CP.

[0208] <Configuration Example 6 of Display Panel 700> The display panel 700 also includes an insulating film 528 (see FIG. 5A).

[0209] "Insulating Film 528" The insulating film 528 has a region sandwiched between the insulating film 521 and the base material 770, and has an opening in a region overlapping with the display element 550(i, j) (see FIG. 5(A)).

[0210] For example, the material that can be used for the insulating film 521 can be used for the insulating film 528. Specifically, the insulating film 528 can be a silicon oxide film, a film containing an acrylic resin, a film containing polyimide, or the like.

[0211] "Insulating Film 573" The insulating film 573 has a region where the display element 550(i, j) is sandwiched between the insulating film 573 and the functional layer 520 (see FIG. 5(A)).

[0212] For example, a single film or a laminated film in which a plurality of films are laminated can be used for the insulating film 573. Specifically, a laminated film in which insulating film 573A formed by a method that is unlikely to damage display element 550(i,j) and dense insulating film 573B with few defects are laminated can be used for the insulating film 573. This can suppress diffusion of impurities into display element 550(i,j).

[0213] Configuration example 2 of display element 550(i,j) Display element 550(i,j) has a function of emitting light.

[0214] The display element 550(i,j) includes a layer 553(j) containing a light-emitting material (see FIG. 5(A)).

[0215] For example, a display element having a function of emitting light can be used as the display element 550(i,j). Specifically, an organic electroluminescence element, an inorganic electroluminescence element, a light-emitting diode, a QDLED (Quantum Dot LED), or the like can be used as the display element 550(i,j).

[0216] Example 1 of the configuration of layer 553(j) containing a luminescent material For example, a long strip of laminated material extending in the column direction along the signal line S21(j) can be used for the layer 553(j) containing the light-emitting material.

[0217] Specifically, materials that emit light with different hues can be used for layer 553(j), layer 553(j+1), and layer 553(j+2) containing a light-emitting material, which allows the hues of light emitted by display elements 550(i,j) to differ from one column to another.

[0218] For example, a blue light emitting material, a green light emitting material, and a red light emitting material can be used as materials that emit light of different hues.

[0219] Example 2 of the layer 553(j) containing a luminescent material For example, a layer of material laminated to emit white light may be used for layer 553(j) containing the luminescent material.

[0220] Specifically, materials that emit light of different hues can be used in layer 553(j) that includes a light-emitting material.

[0221] For example, a laminated material obtained by laminating a layer including a luminescent material including a phosphor that emits blue light and a layer including a material other than the phosphor that emits green and red light can be used for the layer including the luminescent material 553(j). Or, a laminated material obtained by laminating a layer including a material other than the phosphor that emits yellow light can be used for the layer including the luminescent material 553(j).

[0222] For example, the light-emitting unit can be used in the layer 553(j) containing the light-emitting material. The light-emitting unit has one region where an electron injected from one side recombines with a hole injected from the other side. The light-emitting unit also contains a light-emitting material, and the light-emitting material emits energy generated by the recombination of the electron and hole as light.

[0223] For example, a plurality of light-emitting units and an intermediate layer can be used in the layer 553(j) containing a light-emitting material. The intermediate layer has a region sandwiched between two light-emitting units. The intermediate layer has a charge generating region, and has a function of supplying holes to the light-emitting unit arranged on the cathode side and supplying electrons to the light-emitting unit arranged on the anode side. A configuration having a plurality of light-emitting units and an intermediate layer is sometimes called a tandem-type light-emitting element.

[0224] For example, light-emitting units containing materials that emit light of one hue and light-emitting units containing materials that emit light of another hue may be used in layer 553(j) that contains light-emitting materials.

[0225] For example, a high molecular weight compound (oligomer, dendrimer, polymer, etc.), a medium molecular weight compound (a compound in the intermediate range between a low molecular weight and a high molecular weight: molecular weight of 400 or more and 4000 or less), etc. can be used in the layer 553(j) containing a light-emitting material.

[0226] 《Electrode 551(i,j), electrode 552》 The electrode 551(i,j) is electrically connected to the pixel circuit 530(i,j) through the opening 591A (see FIG. 4(A) or FIG. 5(A)).

[0227] The electrode 551(i,j) has an insulating film 528 on its periphery. In other words, the insulating film 528 has an opening, and the electrode 551(i,j) overlaps with the opening. This makes it possible to prevent a short circuit between the electrode 551(i,j) and the electrode 552.

[0228] For example, a material that can be used for a wiring or the like can be used for the electrode 551(i,j) or the electrode 552. Specifically, a material that transmits visible light can be used for the electrode 551(i,j) or the electrode 552.

[0229] For example, a conductive oxide or a conductive oxide containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide with gallium added, or the like can be used. Alternatively, a metal film that is thin enough to transmit light can be used. Alternatively, a material that transmits visible light can be used.

[0230] For example, a metal film that transmits part of the light and reflects the other part of the light can be used for electrode 551(i,j) or electrode 552. This makes it possible to adjust the distance between electrode 551(i,j) and electrode 552, for example. Or, a microresonator structure can be provided in display element 550(i,j). Or, light of a predetermined wavelength can be extracted more efficiently than other light. Or, light with a narrow half-width of the spectrum can be extracted. Or, light of a vivid color can be extracted.

[0231] For example, a film that efficiently reflects light can be used for the electrode 551(i,j) or the electrode 552. Specifically, a material containing silver, palladium, or the like or a material containing silver, copper, or the like can be used for the metal film.

[0232] <Configuration Example 7 of Display Panel 700> The display panel 700 includes a base material 510, a base material 770, and a sealing material 705 (see FIG. 5(A)). The display panel 700 also includes a functional film 770P.

[0233] 《Base material 510, base material 770》 A material having optical transparency can be used for the substrate 510 or the substrate 770 .

[0234] For example, a flexible material can be used for the base material 510 or the base material 770. In this way, a flexible display panel can be provided.

[0235] For example, a material with a thickness of 0.7 mm or less and 0.1 mm or more can be used. Specifically, a material that has been polished to a thickness of about 0.1 mm can be used. This allows the weight to be reduced.

[0236] For example, a glass substrate of 6th generation (1500 mm×1850 mm), 7th generation (1870 mm×2200 mm), 8th generation (2200 mm×2400 mm), 9th generation (2400 mm×2800 mm), 10th generation (2950 mm×3400 mm), etc. can be used for the base material 510 or the base material 770. This makes it possible to manufacture a large display device.

[0237] An organic material, an inorganic material, or a composite material such as an organic material and an inorganic material can be used for the substrate 510 or the substrate 770 .

[0238] For example, inorganic materials such as glass, ceramics, and metals can be used. Specifically, alkali-free glass, soda-lime glass, potash glass, crystal glass, aluminosilicate glass, tempered glass, chemically strengthened glass, quartz, sapphire, or the like can be used for the substrate 510 or substrate 770. Alternatively, aluminosilicate glass, tempered glass, chemically strengthened glass, sapphire, or the like can be suitably used for the substrate 510 or substrate 770 disposed on the side of the display panel closer to the user. This can prevent the display panel from being damaged or scratched during use.

[0239] Specifically, an inorganic oxide film, an inorganic nitride film, an inorganic oxynitride film, etc. can be used. For example, a silicon oxide film, a silicon nitride film, a silicon oxynitride film, an aluminum oxide film, etc. can be used. Stainless steel, aluminum, etc. can be used for the substrate 510 or the substrate 770.

[0240] For example, a single crystal semiconductor substrate made of silicon or silicon carbide, a polycrystalline semiconductor substrate, a compound semiconductor substrate such as silicon germanium, an SOI substrate, or the like can be used for the base material 510 or the base material 770. This allows a semiconductor element to be formed on the base material 510 or the base material 770.

[0241] For example, organic materials such as resin, resin film, or plastic can be used for the substrate 510 or substrate 770. Specifically, materials including polyester, polyolefin, polyamide (nylon, aramid, etc.), polyimide, polycarbonate, polyurethane, or acrylic resin, epoxy resin, or resin having siloxane bonds can be used for the substrate 510 or substrate 770. For example, resin films, resin plates, laminated materials, etc. including these materials can be used. This can reduce the weight. Or, for example, the frequency of occurrence of breakage due to dropping can be reduced.

[0242] Specifically, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), cycloolefin polymer (COP), cycloolefin copolymer (COC), or the like can be used for the substrate 510 or substrate 770 .

[0243] For example, a composite material in which a metal plate, a thin glass plate, or a film of an inorganic material or the like is bonded to a resin film or the like can be used for the substrate 510 or the substrate 770. For example, a composite material in which fibrous or particulate metal, glass, inorganic material, or the like is dispersed in a resin can be used for the substrate 510 or the substrate 770. For example, a composite material in which fibrous or particulate resin, organic material, or the like is dispersed in an inorganic material can be used for the substrate 510 or the substrate 770.

[0244] Furthermore, a single layer material or a material having multiple layers laminated thereon can be used for the substrate 510 or substrate 770. For example, a material having an insulating film or the like laminated thereon can be used. Specifically, a material having one or more films selected from a silicon oxide layer, a silicon nitride layer, a silicon oxynitride layer, or the like laminated thereon can be used. This can prevent, for example, the diffusion of impurities contained in the substrate. Alternatively, it can prevent the diffusion of impurities contained in glass or resin. Alternatively, it can prevent the diffusion of impurities that permeate the resin.

[0245] Also, paper or wood may be used for the substrate 510 or substrate 770 .

[0246] For example, a material having a heat resistance sufficient to withstand heat treatment during the manufacturing process can be used for the base material 510 or the base material 770. Specifically, a material having a heat resistance sufficient to withstand heat applied during a manufacturing process in which a transistor, a capacitor, or the like is directly formed can be used for the base material 510 or the base material 770.

[0247] For example, a method can be used in which an insulating film, a transistor, a capacitor, or the like is formed on a process substrate that has heat resistance to heat applied during the manufacturing process, and the formed insulating film, transistor, capacitor, or the like is transferred to, for example, the base material 510 or the base material 770. In this way, for example, an insulating film, a transistor, a capacitor, or the like can be formed on a substrate that has flexibility.

[0248] "Sealing material 705" The sealing material 705 has an area sandwiched between the functional layer 520 and the substrate 770, and has the function of bonding the functional layer 520 and the substrate 770 together.

[0249] The sealing material 705 can be an inorganic material, an organic material, or a composite material of an inorganic material and an organic material.

[0250] For example, the sealant 705 can be made of an organic material such as a heat-meltable resin or a curable resin.

[0251] For example, the sealant 705 may be made of an organic material such as a reaction curing adhesive, a photocuring adhesive, a heat curing adhesive, and / or an anaerobic adhesive.

[0252] Specifically, adhesives containing epoxy resin, acrylic resin, silicone resin, phenol resin, polyimide resin, imide resin, PVC (polyvinyl chloride) resin, PVB (polyvinyl butyral) resin, EVA (ethylene vinyl acetate) resin, etc. can be used for the sealing material 705.

[0253] <Configuration Example 8 of Display Panel 700> The display panel 700 includes a functional layer 720 and a functional film 770P (see FIG. 5(A)).

[0254] <Functional Layer 720> The functional layer 720 includes an absorption layer CF(j), an insulating film 771, a color conversion layer CC(j), and a light-shielding film BM.

[0255] The absorbing layer CF(j) has a region sandwiched between the substrate 770 and the display element 550(i,j). The color conversion layer CC(j) has a region sandwiched between the absorbing layer CF(j) and the display element 550(i,j).

[0256] For example, a material that selectively transmits light of a predetermined color can be used for the absorbing layer CF(j). Specifically, a material that transmits red light, green light, or blue light can be used for the absorbing layer CF(j).

[0257] 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 CC(j). 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. 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.

[0258] The light shielding film BM has an opening in a region overlapping with the pixel 702(i,j).

[0259] For example, a material that is liquid repellent to a solution containing a material used for the absorbing layer CF(j) can be used for the insulating film 771. Specifically, a material having a contact angle of 90° or more with respect to the solution can be used for the insulating film 771. For example, a material containing fluorine, silicon, or the like can be used for the insulating film 771. This makes it possible to form the absorbing layer CF(j) by using an inkjet method or the like. Alternatively, the manufacturing cost of the absorbing layer CF(j) can be reduced.

[0260] Furthermore, for example, the insulating film 771 may be made of a material that is liquid repellent with respect to a solution that contains the material used for the color conversion layer CC(j).

[0261] 《Functional membrane 770P, etc.》 The functional film 770P has an area that overlaps with the display element 550(i,j).

[0262] 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.

[0263] 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.

[0264] Specifically, a circularly polarizing film can be used for the functional film 770P.

[0265] 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, anti-reflection films, non-glossy films (anti-glare films), and hard coat films that prevent scratches from occurring during use.

[0266] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0267] (Embodiment 2) In this embodiment, a structure of a display panel according to one embodiment of the present invention will be described with reference to FIGS. 3, 6, and 7. FIG.

[0268] FIG. 7 illustrates a structure of a display panel according to one embodiment of the present invention.

[0269] <Display panel configuration example 1.> A display panel 700 described in this embodiment has a display area 231 (see FIG. 7).

[0270] Configuration example 1 of display area 231 The display area 231 has a group of pixels 702(i,1) through 702(i,n), another group of pixels 702(1,j) through 702(m,j), a scanning line G21(i), and a signal line S21(j) (see FIG. 7). Note that i is an integer between 1 and m, j is an integer between 1 and n, and m and n are integers greater than or equal to 1.

[0271] Although not shown, the display area 231 also has a conductive film VCOM2 and a conductive film ANO.

[0272] A group of pixels 702(i,1) to 702(i,n) are arranged in the row direction (the direction indicated by the arrow R1 in the figure), and the group of pixels 702(i,1) to 702(i,n) includes pixel 702(i,j).

[0273] Another group of pixels 702(1,j) to 702(m,j) are arranged in a column direction (the direction indicated by the arrow C1 in the figure) that intersects the row direction, and the other group of pixels 702(1,j) to 702(m,j) includes pixel 702(i,j).

[0274] The scanning line G21(i) is electrically connected to a group of pixels 702(i,1) to 702(i,n) arranged in the row direction.

[0275] The signal line S21(j) is electrically connected to another group of pixels 702(1,j) through 702(m,j) arranged in the column direction.

[0276] This makes it possible to supply image information to a plurality of pixels, thereby providing a novel display panel that is highly convenient and reliable.

[0277] Configuration example 2 of display area 231 The display area 231 includes a plurality of pixels arranged in a matrix. For example, the display area 231 includes 7600 or more pixels in the row direction, and 4300 or more pixels in the column direction. Specifically, the display area 231 includes 7680 pixels in the row direction, and 4320 pixels in the column direction.

[0278] Configuration example 3 of display area 231 The diagonal length of the display area 231 is 40 inches or more, preferably 60 inches or more, and more preferably 80 inches or more. In addition, if the diagonal length of the display area 231 is, for example, 150 inches or less, this is preferable because the weight can be reduced.

[0279] This makes it possible to display a high-definition image, thereby providing a novel display panel that is highly convenient and reliable.

[0280] Configuration example 4 of display area 231 The display area 231 includes a plurality of pixels. The plurality of pixels have a function of displaying colors having different hues. Alternatively, the plurality of pixels can be used to display colors of hues that cannot be displayed by each pixel by additive color mixing.

[0281] In addition, when a plurality of pixels capable of displaying colors with different hues are used for color mixing, each pixel can be referred to as a sub-pixel, and a group of a plurality of sub-pixels can be referred to as a pixel.

[0282] For example, pixel 702(i,j) can be referred to as a subpixel, and pixels 702(i,j), 702(i,j+1), and 702(i,j+2) can be grouped together and referred to as pixel 703(i,k) (see FIG. 3(C)).

[0283] Specifically, a set of subpixels that display blue, green, and red can be used for pixel 703(i,k). Also, a set of subpixels that display cyan, magenta, and yellow can be used for pixel 703(i,k).

[0284] Furthermore, for example, a sub-pixel that displays white or the like can be added to the above set and used in the pixel.

[0285] <Display panel configuration example 2.> The display panel 700 described in this embodiment includes one or more driver circuits, for example, a driver circuit GD and a driver circuit SD (see FIG. 7).

[0286] <Drive circuit GDA, drive circuit GDB> The driving circuit GDA and the driving circuit GDB can be used for the driving circuit GD. For example, the driving circuit GDA and the driving circuit GDB have a function of supplying a selection signal based on control information.

[0287] Specifically, the display has a function of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, based on control information, thereby enabling smooth display of moving images.

[0288] Alternatively, the display device may have a function of supplying a selection signal to one scanning line at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute, based on control information. This makes it possible to display a still image with reduced flicker.

[0289] When multiple driving circuits are provided, for example, the frequency with which the driving circuit GDA supplies a selection signal can be made different from the frequency with which the driving circuit GDB supplies a selection signal. Specifically, the selection signal can be supplied to one area displaying a still image more frequently than the frequency with which the selection signal is supplied to another area displaying a moving image. This makes it possible to display a still image with suppressed flicker in one area and display a smooth moving image in the other area.

[0290] Incidentally, the frame frequency can be made variable. For example, display can be performed at a frame frequency of 1 Hz or more and 120 Hz or less. Alternatively, display can be performed at a frame frequency of 120 Hz using the progressive method.

[0291] For example, a bottom-gate transistor or a top-gate transistor can be used in the driver circuit GD. Specifically, a transistor MD can be used in the driver circuit GD (see FIG. 6).

[0292] Note that, for example, a semiconductor film used for a transistor in the driver circuit GD can be formed in the process of forming a semiconductor film used for a transistor in the pixel circuit 530(i,j).

[0293] <Drive circuit SD> The drive circuit SD has a function of generating an image signal based on information V11, and a function of supplying the image signal to a pixel circuit electrically connected to one display element (see FIG. 7).

[0294] For example, various sequential circuits such as a shift register can be used for the driver circuit SD.

[0295] For example, an integrated circuit formed on a silicon substrate can be used for the driver circuit SD.

[0296] For example, the integrated circuit can be connected to the terminals by using a chip on glass (COG) method or a chip on film (COF) method. Specifically, the integrated circuit can be connected to the terminals by using an anisotropic conductive film.

[0297] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0298] (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.

[0299] 8A to 8B are diagrams illustrating a configuration of a display device of one embodiment of the present invention. Fig. 8A is a block diagram of a display device of one embodiment of the present invention, and Figs. 8B-1 to 8B-3 are projection views illustrating an external appearance of the display device of one embodiment of the present invention.

[0300] <Example of display device configuration> The display device described in this embodiment includes a control unit 238 and a display panel 700 (see FIG. 8(A)).

[0301] Configuration example 1 of control unit 238 The control unit 238 is supplied with the image information V1 and the control information CI. For example, a clock signal or a timing signal can be used as the control information CI.

[0302] The control unit 238 generates information V11 based on the image information V1, and generates a control signal SP based on the control information CI, and also supplies the information V11 and the control signal SP.

[0303] For example, the information V11 includes a gradation of 8 bits or more, preferably 12 bits or more. Also, for example, a clock signal or a start pulse of a shift register used in a driving circuit can be used as the control signal SP.

[0304] <Configuration example 2 of control unit 238> For example, the decompression circuit 234 and the image processing circuit 235 can be used in the control unit 238 .

[0305] 《Extension circuit 234》 The decompression circuit 234 has a function of decompressing the image information V1 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.

[0306] "Image processing circuit 235" The image processing circuit 235 includes, for example, a storage area. The storage area includes, for example, a function for storing information included in the image information V1.

[0307] The image processing circuit 235 has, for example, a function of correcting the image information V1 based on a predetermined characteristic curve to generate information V11, and a function of supplying the information V11.

[0308] <Display panel configuration example 1.> Information V11 and a control signal SP are supplied to the display panel 700. For example, a driver circuit can be used for the display panel 700. Specifically, the display panel 700 described in the second embodiment can be used.

[0309] <Drive circuit> The drive circuits operate based on a control signal SP. By using the control signal SP, the operations of a plurality of drive circuits can be synchronized.

[0310] For example, the drive circuit GDA(1), drive circuit GDA(2), drive circuit GDB(1), and drive circuit GDB(2) can be used in a display panel. In addition, the drive circuit GDA(1), drive circuit GDA(2), drive circuit GDB(1), and drive circuit GDB(2) are supplied with a control signal SP and have a function of supplying a selection signal.

[0311] For example, the drive circuit SDA(1), drive circuit SDA(2), drive circuit SDB(1), drive circuit SDB(2), drive circuit SDC(1), and drive circuit SDC(2) can be used in a display panel. In addition, the drive circuit SDA(1), drive circuit SDA(2), drive circuit SDB(1), drive circuit SDB(2), drive circuit SDC(1), and drive circuit SDC(2) are supplied with the control signal SP and information V11 and can supply an image signal.

[0312] Configuration example 3 of pixel 702(i,j) Pixel 702(i,j) is displayed based on information V11.

[0313] This allows image information to be displayed using the display element. As a result, a novel display device with excellent convenience or reliability can be provided. Alternatively, for example, a television receiving system (see FIG. 8(B-1)), a video monitor (see FIG. 8(B-2)), or a notebook computer (see FIG. 8(B-3)) can be provided.

[0314] <Display panel configuration example 2.> For example, the control circuit 233 can be used in the display panel 700. Specifically, the control circuit 233 formed on a rigid substrate can be used in the display panel 700. In addition, the control circuit 233 formed on the rigid substrate can be electrically connected to the control unit 238 by using a flexible printed circuit board.

[0315] <<Control circuit 233>> The control circuit 233 has a function of generating and supplying a control signal SP. For example, a clock signal or a timing signal can be used as the control signal SP. Specifically, a timing controller can be used for the control circuit 233.

[0316] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0317] (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.

[0318] FIG. 9 is a block diagram illustrating a configuration of an input / output device of one embodiment of the present invention.

[0319] <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. 9).

[0320] 《Display section 230》 The display unit 230 includes a display panel. For example, the display panel 700 described in embodiment 1 or 2 can be used for the display unit 230. Note that a configuration including the input unit 240 and the display unit 230 can be referred to as an input / output panel 700TP.

[0321] Configuration example 1 of input unit 240 The input unit 240 has a detection area 241. The input unit 240 has a function of detecting an object approaching the detection area 241.

[0322] The sensing region 241 comprises the area that overlaps with pixel 702(i,j).

[0323] 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, a novel input / output device that is highly convenient and reliable can be provided.

[0324] Configuration example 2 of input unit 240 The input section 240 comprises an oscillator circuit OSC and a detection circuit DC (see FIG. 9).

[0325] "Detection Area 241" Sensing region 241 may, for example, comprise one or more sensing elements.

[0326] The sensing region 241 has a group of sensing elements 775(g,1) through 775(g,q) and another group of sensing elements 775(1,h) through 775(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.

[0327] A group of detector elements 775(g,1) to 775(g,q) includes a detector element 775(g,h) and is arranged in the row direction (the direction indicated by the arrow R2 in the figure). Note that the direction indicated by the arrow R2 may be the same as the direction indicated by the arrow R1, or may be different.

[0328] Another group of detector elements 775(1,h) to 775(p,h) includes the detector element 775(g,h) and is arranged in a column direction (the direction indicated by the arrow C2 in the drawing) that intersects with the row direction.

[0329] Detector Element The sensing element 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.

[0330] 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 detection element.

[0331] Furthermore, detection elements of multiple types can be used in combination. For example, a detection element that detects a finger and a detection element that detects a stylus pen can be used in combination.

[0332] 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.

[0333] Specifically, a finger can be detected using a capacitance type or optical type proximity sensor, or a stylus pen can be detected using an electromagnetic induction type or optical type proximity sensor.

[0334] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

Note that in the diagram, 1Frame represents one frame, and Time, which is indicated with an arrow, represents the passage of time.

[0339] <Configuration example 1 of information processing device> The information processing device described in this embodiment includes an arithmetic device 210 and an input / output device 220 (see FIG. 10(A)). Note that the input / output device is electrically connected to the arithmetic device 210. The information processing device 200 may include a housing (see FIG. 10(B) or FIG. 10(C)).

[0340] Configuration example 1 of the arithmetic device 210 The arithmetic unit 210 is supplied with input information II or sensed information DS. Based on the input information II or sensed information DS, the arithmetic unit 210 generates control information CI and image information VI, and supplies the control information CI and image information V1.

[0341] 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.

[0342] The transmission path 214 is electrically connected to the calculation unit 211 , the storage unit 212 , and the input / output interface 215 .

[0343] 《Arithmetic section 211》 The calculation unit 211 has a function of executing a program, for example.

[0344] 《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.

[0345] Specifically, a hard disk, a flash memory, a memory including a transistor including an oxide semiconductor, or the like can be used.

[0346] 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.

[0347] 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.

[0348] Example of the configuration of the input / output device 220 The input / output device 220 supplies the input information II and the detection information DS. The input / output device 220 is supplied with the control information CI and the image information V1 (see FIG. 10(A)).

[0349] 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.

[0350] For example, a signal for controlling the luminance, saturation, or hue of the image information V1 may be used as the control information CI, or a signal for changing the display of a part of the image information V1 may be used as the control information CI.

[0351] 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.

[0352] Configuration example of display unit 230 The display unit 230 displays the image information V1 based on the control information CI.

[0353] The display unit 230 includes a control unit 238, a drive circuit GD, a drive circuit SD, and a display panel 700 (see FIG. 8). For example, the display device described in the third embodiment can be used for the display unit 230.

[0354] Example of configuration of input unit 240 The input unit 240 generates input information II. For example, the input unit 240 has a function of supplying position information P1.

[0355] For example, a human interface or the like can be used for the input unit 240 (see FIG. 10(A)). Specifically, a keyboard, a mouse, a touch sensor, a microphone, a camera, or the like can be used for the input unit 240.

[0356] 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.

[0357] 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.

[0358] 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.

[0359] 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.

[0360] 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.

[0361] 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.

[0362] 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 sensor, a temperature sensor, a humidity sensor, a camera, or the like.

[0363] 《Communication Section 290》 The communication unit 290 has a function of supplying information to the network and acquiring information from the network.

[0364] 《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.

[0365] This makes it possible to generate control information based on input information or detection information. Or, it is possible to display image information based on input information or detection information. Or, it is possible for the information processing device to operate by grasping the intensity of light received by the housing of the information processing device in the environment in which the information processing device is used. Or, it is possible for the user of the information processing device to select the display method. As a result, it is possible to provide a novel information processing device that is highly convenient or reliable.

[0366] 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.

[0367] Configuration example 2 of the arithmetic device 210 The arithmetic device 210 includes an artificial intelligence unit 213 (see FIG. 10(A)). The artificial intelligence unit 213 generates control information CI based on input information II or detection information DS.

[0368] [Natural language processing for input information II] Specifically, the artificial intelligence unit 213 can perform natural language processing on the input information II and extract one feature from the entire input information II. For example, the artificial intelligence unit 213 can infer emotions and the like contained in the input information II and make them a feature. It can also infer a color, pattern, font, and the like that is empirically felt to be suitable for the feature. The artificial intelligence unit 213 can also generate information that specifies the color, pattern, or font of characters, and information that specifies the color or pattern of the background, and use the information in the control information CI.

[0369] Specifically, the artificial intelligence unit 213 can extract some words contained in the input information II by natural language processing of the input information II. For example, the artificial intelligence unit 213 can extract grammatical errors, factual errors, or expressions containing emotions. In addition, the artificial intelligence unit 213 can generate control information CI that displays the extracted part in a color, pattern, font, or the like different from the other parts, and use the control information CI.

[0370] [Image processing for input information II] Specifically, the artificial intelligence unit 213 can perform image processing on the input information II and extract one feature from the input information II. For example, the artificial intelligence unit 213 can infer the year in which the input information II was photographed, whether indoors or outdoors, day or night, and the like, and use these as features. In addition, the artificial intelligence unit 213 can infer a color tone that is empirically felt to be suitable for the feature, and generate control information CI for using the color tone for display. Specifically, information specifying a color (for example, full color, black and white, or brown, etc.) used to express shading can be used in the control information CI.

[0371] Specifically, the artificial intelligence unit 213 can extract a part of an image included in the input information II by performing image processing on the input information II. For example, the artificial intelligence unit 213 can generate control information CI that displays a boundary between one part of the extracted image and another part. Specifically, the artificial intelligence unit 213 can generate control information CI that displays a rectangle that surrounds a part of the extracted image.

[0372] [Inference using detection information DS] Specifically, the artificial intelligence unit 213 can generate an inference using the detection information DS. Alternatively, the artificial intelligence unit 213 can generate control information CI based on the inference RI so that the user of the information processing device 200 feels comfortable.

[0373] Specifically, the artificial intelligence unit 213 can generate control information CI for adjusting the brightness of the display so that the brightness of the display is felt to be comfortable based on the illuminance of the environment, etc. Alternatively, the artificial intelligence unit 213 can generate control information CI for adjusting the volume so that the volume is felt to be comfortable based on the noise of the environment, etc.

[0374] Note that a clock signal or a timing signal supplied to the control unit 238 included in the display unit 230 can be used as the control information CI. Alternatively, a clock signal or a timing signal supplied to the control unit 248 included in the input unit 240 can be used as the control information CI.

[0375] <Configuration example 2 of information processing device> Another configuration of the data processing device of one embodiment of the present invention will be described with reference to FIGS.

[0376] "program" A program according to one embodiment of the present invention has the following steps (see FIG. 11(A)).

[0377] [First step] In the first step, the settings are initialized (see FIG. 11(A)(S1)).

[0378] For example, predetermined image information to be displayed at the time of startup, a predetermined mode for displaying the image information, and information for specifying a predetermined display method for displaying the image information are obtained from the storage unit 212. Specifically, one still image information or other moving image information can be used as the predetermined image information. Also, the first mode or the second mode can be used as the predetermined mode.

[0379] [Second step] In the second step, interrupt processing is permitted (see FIG. 11(A)(S2)). Note that the arithmetic unit for which interrupt processing is permitted can perform the interrupt processing in parallel with the main processing. The arithmetic unit that has returned from the interrupt processing to the main processing can reflect the results obtained from the interrupt processing in the main processing.

[0380] When the counter value is the initial value, the arithmetic unit may perform an interrupt process, and when returning from the interrupt process, the counter may be set to a value other than the initial value. This allows interrupt processing to be always performed after the program is started.

[0381] [Third step] In a third step, the image information is displayed using a predetermined mode or a predetermined display method selected in the first step or interrupt process (see FIG. 11(A)(S3)). Note that the predetermined mode specifies the mode in which the information is displayed, and the predetermined display method specifies the method in which the image information is displayed. Also, for example, it can be used for information that displays image information V1.

[0382] For example, one way of displaying the image information V1 can be associated with a first mode, and another way of displaying the image information V1 can be associated with a second mode, allowing the display method to be selected based on the selected mode.

[0383] First mode Specifically, a method of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, and performing display based on the selection signal can be associated with the first mode.

[0384] For example, if the selection signal is supplied at a frequency of 30 Hz or more, and preferably 60 Hz or more, the movement of the moving image can be displayed smoothly.

[0385] For example, by updating the image at a frequency of 30 Hz or more, preferably 60 Hz or more, an image that changes so as to smoothly follow the user's operation can be displayed on the information processing device 200 being operated by the user.

[0386] Second Mode Specifically, a method of supplying a selection signal to one scan line at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute, and performing display based on the selection signal, can be associated with the second mode.

[0387] Supplying the selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute can provide a display with reduced flicker or blinking, and can also reduce power consumption.

[0388] For example, when the information processing device 200 is used in a clock, the display can be updated once per second or once per minute.

[0389] Incidentally, for example, when a light-emitting element is used as a display element, the light-emitting element can be made to emit light in a pulsed manner to display image information. Specifically, the organic EL element can be made to emit light in a pulsed manner, and the afterglow can be used for display. Since the organic EL element has excellent frequency characteristics, it may be possible to shorten the time for driving the light-emitting element and reduce power consumption. Or, since heat generation is suppressed, it may be possible to reduce deterioration of the light-emitting element.

[0390] [Fourth step] In the fourth step, if an end command is supplied, the process proceeds to the fifth step, and if an end command is not supplied, the process proceeds to the third step (see FIG. 11(A)(S4)).

[0391] For example, the end command supplied in the interrupt process may be used for the judgment.

[0392] [5th ​​step] In the fifth step, the process ends (see FIG. 11(A)(S5)).

[0393] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 11(B)).

[0394] [Sixth step] In a sixth step, for example, the detection unit 250 detects the illuminance of the environment in which the information processing device 200 is used (see FIG. 11(B)(S6)). Note that instead of the illuminance of the environment, the color temperature or chromaticity of the ambient light may be detected.

[0395] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (see FIG. 11(B)(S7)). For example, the brightness of the display is determined so as not to be too dark or too bright.

[0396] It should be noted that if the color temperature or chromaticity of the ambient light is detected in the sixth step, the color of the display may be adjusted.

[0397] [8th step] In the eighth step, the interrupt process ends (see FIG. 11(B) (S8)).

[0398] <Configuration example 3 of information processing device> Another configuration of the data processing device of one embodiment of the present invention will be described with reference to FIG.

[0399] Fig. 12A is a flowchart illustrating a program according to one embodiment of the present invention, which illustrates an interrupt process different from the interrupt process illustrated in Fig. 11B.

[0400] Note that the configuration example 3 of the information processing device differs from the interrupt processing described with reference to Fig. 11(B) in that the interrupt processing includes a step of changing the mode based on a given event that is supplied. Here, the different parts will be described in detail, and the above description will be used for parts where a similar configuration can be used.

[0401] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 12(A)).

[0402] [Sixth step] In the sixth step, if a predetermined event is supplied, the process proceeds to the seventh step, and if the predetermined event is not supplied, the process proceeds to the eighth step (see FIG. 12(A)(U6)). For example, whether or not a predetermined event is supplied within a predetermined period of time can be used as a condition. Specifically, the predetermined period can be a period of 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less, but longer than 0 seconds.

[0403] [Seventh step] In the seventh step, the mode is changed (see FIG. 12(A)(U7)). Specifically, if the first mode has been selected, the second mode is selected, and if the second mode has been selected, the first mode is selected.

[0404] For example, it is possible to change the display mode for a part of the region of the display unit 230. Specifically, it is possible to change the display mode for a region to which a selection signal is supplied by one of the drive circuits of the display unit 230 including the drive circuits GDA, GDB, and GDC (see FIG. 12(B)).

[0405] For example, when a predetermined event is supplied to the input unit 240 in an area overlapping with an area to which the drive circuit GDB supplies a selection signal, the display mode of the area to which the drive circuit GDB supplies a selection signal can be changed (see Figs. 12(B) and 12(C)). Specifically, the frequency of the selection signal supplied by the drive circuit GDB can be changed in response to a "tap" event supplied to the touch panel using a finger or the like.

[0406] The signal GCLK is a clock signal that controls the operation of the drive circuit GDB, and the signals PWC1 and PWC2 are pulse width control signals that control the operation of the drive circuit GDB. The drive circuit GDB supplies selection signals to the scanning lines G21(m+1) to G21(2m) based on the signals GCLK, PWC1, and PWC2.

[0407] This allows, for example, the driver circuit GDB to supply a selection signal without the driver circuit GDA and the driver circuit GDC supplying a selection signal. Alternatively, the display of the area to which the driver circuit GDB supplies a selection signal can be updated without changing the display of the area to which the driver circuit GDA and the driver circuit GDC supply a selection signal. Alternatively, the power consumed by the driver circuit can be reduced.

[0408] [8th step] In the eighth step, the interrupt process is ended (see FIG. 12(A)(U8)). Note that the interrupt process may be repeatedly executed during the execution of the main process.

[0409] 《Specified Event》 For example, events such as "click" and "drag" provided using a pointing device such as a mouse, and events such as "tap," "drag," or "swipe" provided to a touch panel using a finger or the like as a pointer can be used.

[0410] Also, for example, the position of the slide bar pointed to by the pointer, the swipe speed, the drag speed, etc. can be used to provide arguments for commands associated with a given event.

[0411] For example, the information detected by the detection unit 250 can be compared with a preset threshold value, and the comparison result can be used for the event.

[0412] Specifically, a pressure-sensitive detector that comes into contact with a button or the like that is arranged so that it can be pressed into the housing can be used for the detection unit 250 .

[0413] Commands associated with specific events For example, the termination command may be associated with a certain event.

[0414] For example, a "page turn command" for switching the display from one image information to another can be associated with a specific event. In addition, an argument for determining the page turning speed used when executing the "page turn command" can be given using the specific event.

[0415] For example, a "scroll command" that moves the display position of a part of an image information and displays another part that is adjacent to the part can be associated with a specific event. Note that an argument that determines the speed at which the display is moved when the "scroll command" is executed can be given using the specific event.

[0416] For example, a command to set a display method or a command to generate image information can be associated with a specific event. An argument that determines the brightness of an image to be generated can be associated with a specific event. The argument that determines the brightness of an image to be generated can also be determined based on the brightness of the environment detected by the detection unit 250.

[0417] For example, a command to obtain information distributed using a push-type service using the communication unit 290 can be associated with a specific event.

[0418] The presence or absence of qualification to obtain information may be determined using location information detected by the detection unit 250. Specifically, it may be determined that the user is qualified to obtain information when the user is inside or in an area of ​​a specific classroom, school, conference room, company, building, etc. As a result, for example, educational materials distributed in a classroom of a school or university, etc., can be received and the information processing device 200 can be used as a textbook, etc. (see FIG. 10(C)). Or, materials distributed in a conference room of a company, etc. can be received and used as conference materials.

[0419] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0420] (Embodiment 6) In this embodiment, a configuration of a data processing device according to one embodiment of the present invention will be described with reference to FIGS.

[0421] 13 and 14 are diagrams illustrating a configuration of an information processing device of one embodiment of the present invention. Fig. 13A is a block diagram of the information processing device, and Figs. 13B to 13E are perspective views illustrating the configuration of the information processing device. Figs. 14A to 14E are perspective views illustrating the configuration of the information processing device.

[0422] <Information processing device> A data processing device 5200B described in this embodiment includes an arithmetic device 5210 and an input / output device 5220 (see FIG. 13A).

[0423] The arithmetic unit 5210 has a function of receiving operation information and a function of supplying image information based on the operation information.

[0424] The input / output device 5220 includes a display unit 5230, an input unit 5240, a detection unit 5250, and a communication unit 5290, a function of supplying operation information, and a function of being supplied with image information. The input / output device 5220 also includes a function of supplying detection information, a function of supplying communication information, and a function of being supplied with communication information.

[0425] The input unit 5240 has a function of supplying operation information. For example, the input unit 5240 supplies operation information based on an operation by a user of the information processing device 5200B.

[0426] Specifically, the input unit 5240 can use a keyboard, a hardware button, a pointing device, a touch sensor, an illuminance sensor, an imaging device, a voice input device, an eye-gaze input device, a posture detection device, or the like.

[0427] The display unit 5230 has a function of displaying a display panel and image information. For example, the display panel described in Embodiment 1 or 2 can be used for the display unit 5230.

[0428] The detection unit 5250 has a function of supplying detection information, for example, a function of detecting the surrounding environment in which the information processing device is used and supplying the detected information.

[0429] Specifically, the detection unit 5250 can include an illuminance sensor, an imaging device, a posture detection device, a pressure sensor, a human sensor, or the like.

[0430] The communication unit 5290 has a function of receiving and supplying communication information. For example, it has a function of connecting to other electronic devices or communication networks by wireless communication or wired communication. Specifically, it has functions such as wireless local area communication, telephone communication, and short-distance wireless communication.

[0431] "Configuration example 1 of information processing device" For example, an outer shape along a cylindrical pillar or the like can be applied to the display unit 5230 (see FIG. 13(B)). In addition, it has a function of changing the display method according to the illuminance of the usage environment. In addition, it has a function of detecting the presence of a person and changing the display content. This allows it to be installed on a pillar of a building, for example. Or, it can display advertisements or guidance, or it can be used for digital signage, etc.

[0432] "Configuration example 2 of information processing device" For example, it has a function of generating image information based on the trajectory of a pointer used by a user (see FIG. 13(C)). Specifically, a display panel with a diagonal length of 20 inches or more, preferably 40 inches or more, and more preferably 55 inches or more can be used. Alternatively, multiple display panels can be arranged to be used in one display area. Alternatively, multiple display panels can be arranged to be used as a multi-screen. This allows the display to be used, for example, in electronic whiteboards, electronic bulletin boards, electronic signs, etc.

[0433] "Configuration example 3 of information processing device" For example, the smartwatch has a function for changing the display method according to the illuminance of the usage environment (see FIG. 13(D)). This can reduce the power consumption of the smartwatch, for example. Alternatively, the smartwatch can display images so that it can be used suitably even in environments with strong external light, such as outdoors on a sunny day.

[0434] "Configuration example 4 of information processing device" The display unit 5230 has, for example, a curved surface that curves gently along the side of the housing (see FIG. 13(E)). Alternatively, the display unit 5230 has a display panel, and the display panel has a function of displaying on, for example, the front, side, and top. This allows image information to be displayed not only on the front of the mobile phone, but also on the side and top.

[0435] "Configuration example 5 of information processing device" For example, the smartphone has a function for changing the display method according to the illuminance of the usage environment (see FIG. 14(A)). This can reduce the power consumption of the smartphone. Alternatively, for example, the smartphone can display images so that it can be used suitably even in an environment with strong external light, such as outdoors on a sunny day.

[0436] "Configuration Example 6 of Information Processing Device" For example, it has a function to change the display method according to the illuminance of the usage environment (see FIG. 14(B)). This allows images to be displayed on the television system so that it can be used conveniently even when strong external light shines indoors on a sunny day.

[0437] "Configuration Example 7 of Information Processing Device" For example, it has a function to change the display method according to the illuminance of the usage environment (see FIG. 14(C)). This allows images to be displayed on the tablet computer so that it can be used suitably even in an environment with strong external light, such as outdoors on a sunny day.

[0438] "Configuration Example 8 of Information Processing Device" For example, it has a function for changing the display method according to the illuminance of the usage environment (see FIG. 14(D)). This allows the subject to be displayed on the digital camera so that it can be viewed appropriately even in an environment with strong external light, such as outdoors on a sunny day.

[0439] "Configuration example 9 of information processing device" For example, the display method can be changed according to the illuminance of the environment in which the device is used (see FIG. 14(E)). This allows images to be displayed on a personal computer so that the device can be used effectively even in an environment with strong external light, such as outdoors on a clear day.

[0440] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0441] 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.

[0442] 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.).

[0443] 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.).

[0444] 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.

[0445] 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.

[0446] 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.

[0447] 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.

[0448] 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.

[0449] 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.

[0450] 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.).

[0451] 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]
