[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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

[0070] 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]

[0087] <Configuration example 1 of function panel 700> The functional panel described in this embodiment includes a driver circuit GD, a driver circuit SD, and a set of pixels 703(i,j) (see FIG. 1A).

[0088] <<Example of the configuration of the drive circuit GD>> The driving circuit GD has a function of supplying a first selection signal and a second selection signal (see FIG. 5A and FIG. 6A). For example, the driving circuit GD is electrically connected to the conductive film G1(i) and supplies a first selection signal, and is electrically connected to the conductive film G2(i) and supplies a second selection signal.

[0089] <<Example of the configuration of the drive circuit SD>> The drive circuit SD has a function of supplying an image signal and a control signal, and the control signal includes a first level and a second level. For example, the drive circuit SD is electrically connected to the conductive film S1g(j) and supplies an image signal, and is electrically connected to the conductive film S2g(j) and supplies a control signal.

[0090] <<Configuration example 1 of pixel 703(i,j)>> The set of pixels 703(i,j) comprises pixel 702G(i,j), which comprises element 550G(i,j) and pixel circuit 530G(i,j) (see FIGS. 1B and 2A).

[0091] Configuration example 1 of pixel circuit 530G(i,j) The pixel circuit 530G(i,j) is supplied with a first selection signal, a second selection signal, an image signal, and a control signal. The pixel circuit 530G(i,j) acquires an image signal based on the first selection signal, and the pixel circuit 530G(i,j) acquires a control signal based on the second selection signal (see FIGS. 5A and 6A). Note that, for example, the operation of supplying the first selection signal and causing the pixel circuit 530G(i,j) to acquire an image signal can be referred to as "writing."

[0092] The pixel circuit 530G(i,j) has a function of holding a first state ST1 to a third state ST3, where the first state ST1 holds a first level, the second state ST2 holds a second level, and the third state ST3 holds an image signal. The period during which the second state ST2 is held is preferably equal to the period during which the first state ST1 is held. This makes it possible to easily process the captured image. The period during which the third state ST3 is held is preferably longer than the period during which the first state ST1 is held. This makes it possible to display image information with high contrast.

[0093] 《Example of the configuration of element 550G(i,j)》 The element 550G(i,j) is electrically connected to the pixel circuit 530G(i,j). The element 550G(i,j) includes an electrode 551G(i,j) electrically connected to the pixel circuit 530G(i,j) and an electrode 552 electrically connected to the conductive film VCOM2 (see FIGS. 3 and 9A).

[0094] The element 550G(i,j) displays a first brightness based on the first state ST1, the element 550G(i,j) displays a second brightness based on the second state ST2, and the element 550G(i,j) displays an image signal based on the third state ST3. Note that the first brightness is darker than the second brightness.

[0095] Thereby, in the first state ST1, the pixel 702G(i,j) can be hidden, for example. Or, in the second state ST2, the pixel 702G(i,j) can be used for illumination. Or, in the third state ST3, the pixel 702G(i,j) can be used to display an image signal. Or, while switching the display of the pixel 702G(i,j) using the first selection signal and image signal, the pixel 702G(i,j) can be hidden or used for illumination using the second selection signal and control signal. Or, the period during which the pixel 702G(i,j) is hidden or the period during which the pixel 702G(i,j) is used for illumination can be inserted into the period during which the image signal is displayed. As a result, a novel functional panel with excellent convenience, usefulness, or reliability can be provided.

[0096] <Configuration example 2 of function panel 700> The functional panel described in this embodiment has a driving circuit RD (see FIG. 1A).

[0097] <<Configuration example of the driver circuit RD>> The driving circuit RD has a function of supplying a third selection signal to a fifth selection signal (see FIG. 5A and FIG. 6A). For example, the driving circuit RD is electrically connected to the conductive film RS(i) and supplies a third selection signal, is electrically connected to the conductive film TX(i) and supplies a fourth selection signal, and is electrically connected to the conductive film SE(i) and supplies a fifth selection signal.

[0098] Configuration example 2 of pixel 703(i,j) The set of pixels 703(i,j) comprises pixel 702S(i,j), which comprises element 550S(i,j) and pixel circuit 530S(i,j) (see FIGS. 1B and 2A).

[0099] <<Configuration Example 1 of Element 550S(i,j)>> The element 550S(i,j) is electrically connected to the pixel circuit 530S(i,j), and has a function of generating an imaging signal (see FIG. 4).

[0100] Configuration Example 1 of Pixel Circuit 530S(i,j) The pixel circuit 530S(i,j) is supplied with a third select signal to a fifth select signal (see FIGS. 5A and 6A).

[0101] For example, the conductive film RS(i) supplies a third selection signal, and the pixel circuit 530S(i,j) is initialized at timing t(0) based on the third selection signal (see FIG. 4 and FIG. 5A). The conductive film TX(i) supplies a fourth selection signal, and the pixel circuit 530S(i,j) acquires an imaging signal at timing t(1) based on the fourth selection signal. The conductive film SE(i) supplies a fifth selection signal, and the pixel circuit 530S(i,j) supplies an imaging signal at timing t(3) based on the fifth selection signal.

[0102] Configuration example 2 of pixel circuit 530G(i,j) The pixel circuit 530G(i,j) holds the first state ST1 or the second state ST2 between timing t(0) and timing t(1), and the pixel circuit 530G(i,j) holds the third state ST3 at timing t(3).

[0103] The operation of supplying the fourth selection signal and causing the pixel circuit 530S(i,j) to acquire an imaging signal can be called "imaging" (see Figs. 5A, 5B, and 6B). The operation of reading out an imaging signal from the pixel circuit 530S(i,j) can be called "reading out". The operation of supplying a predetermined voltage to the element 550S(i,j) can be called "initialization", the operation of exposing the initialized element 550S(i,j) to light for a predetermined period of time can be called "exposure", and the operation of reflecting the voltage changed by exposure to the pixel circuit 530S(i,j) can be called "transfer". In the figures, SRS corresponds to the operation of supplying a reference signal used in the correlated double sampling method, and "output" corresponds to the operation of supplying an imaging signal.

[0104] For example, one frame of image information can be written in 16.7 ms. Specifically, it can operate at a frame rate of 60 Hz. Note that an image signal can be written to the pixel circuit 530G(i,j) in 15.2 μs.

[0105] For example, one frame of image information can be held for a period corresponding to 16 frames, or one frame of imaging information can be captured and read out for a period corresponding to 16 frames.

[0106] Specifically, it can be initialized in 15 μs, exposed in the range of 1 ms to 5 ms, and transferred in 150 μs, or read out in 250 ms.

[0107] The element 550S(i,j) includes an electrode 551S(i,j) electrically connected to the pixel circuit 530S(i,j) and an electrode 552 electrically connected to the conductive film VPD (see FIG. 4 and FIG. 10A). The electrode 552 used for the element 550G(i,j) can be used for the element 550S(i,j). This can simplify the configuration and manufacturing process of the functional panel.

[0108] Thereby, for example, imaging can be performed using the second pixel circuit 530S(i,j) during a period when the first pixel circuit 530G(i,j) is in the first state ST1. Or, for example, imaging can be performed using the second pixel circuit 530S(i,j) during a period when the first pixel circuit 530G(i,j) is in the second state ST2. Or, for example, imaging can be performed using the second pixel 702S(i,j) during a period when the first pixel 702G(i,j) is not displayed. Or, for example, imaging can be performed using the second pixel 702S(i,j) using the first pixel 702G(i,j) for illumination, such as imaging a finger approaching the first pixel 702G(i,j). Or, for example, imaging can be performed under different conditions using the second pixel 702S(i,j) while switching the image information displayed on the first pixel 702G(i,j). Alternatively, information captured with the first pixel 702G(i,j) hidden can be subtracted from information captured with the first pixel 702G(i,j) used as illumination. Alternatively, background information can be subtracted from captured information. Alternatively, by subtracting background information, a finger approaching the first pixel 702G(i,j) can be clearly captured. Alternatively, the present invention can be used as a proximity sensor. Alternatively, the present invention can be used as a display device. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0109] <Configuration example 3 of function panel 700> The functional panel described in this embodiment has a conductive film G1(i), a conductive film G2(i), a conductive film S1g(j), a conductive film S2g(j), and a conductive film ANO (see FIG. 3). The functional panel also has a conductive film G3(i).

[0110] The conductive film G1(i) is supplied with a first selection signal, the conductive film G2(i) is supplied with a second selection signal, the conductive film S1g(j) is supplied with an image signal, and the conductive film S2g(j) is supplied with a control signal (see FIG. 5 or FIG. 6).

[0111] Configuration Example 3 of Pixel Circuit 530G(i,j) The pixel circuit 530G(i,j) includes a node N21, a transistor M21, a switch SW21, and a switch SW22 (see FIG. 3). The pixel circuit 530G(i,j) also includes a node N22, a capacitor C22, and a switch SW23.

[0112] The transistor M21 includes a gate electrode electrically connected to the node N21, a first electrode electrically connected to the element 550G(i,j), and a second electrode electrically connected to the conductive film ANO.

[0113] The switch SW21 has a first terminal electrically connected to the conductive film S1g(j), a second terminal electrically connected to a node N21, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film G1(i).

[0114] The switch SW22 has a first terminal electrically connected to the conductive film S2g(j), a second terminal electrically connected to the node N21, and a function of controlling the conductive state or non-conductive state based on the potential of the conductive film G2(i).

[0115] Element 550G(i,j) has the function of changing the brightness based on the potential of node N21.

[0116] As a result, the potential of the node N21 can be made closer to the potential of the conductive film S1g(j) by using the switch SW21. Alternatively, the potential of the node N21 can be made closer to the potential of the conductive film S2g(j) by using the switch SW22. Alternatively, during a period in which the switch SW21 is in a non-conductive state, the potential of the node N21 can be made closer to the potential of the conductive film S2g(j) by using the switch SW22. Alternatively, during a period in which the switch SW22 is in a non-conductive state, the potential of the node N21 can be made closer to the potential of the conductive film S1g(j) by using the switch SW21. Alternatively, the potential of the node N21 can be made to be in the first state ST1 or the second state ST2 by using the switch SW22. Alternatively, the potential of the node N21 can be made to be in the third state ST3 by using the switch SW21. As a result, a novel functional panel with excellent convenience, usefulness, or reliability can be provided.

[0117] <Configuration example 4 of function panel 700> The functional panel described in this embodiment has a conductive film RS(i), a conductive film TX(i), a conductive film VR, a conductive film VCP, a conductive film VPI, a conductive film WX(j), and a conductive film SE(i) (see FIG. 4).

[0118] The conductive film RS(i) is supplied with a third selection signal, the conductive film TX(i) is supplied with a fourth selection signal, and the conductive film SE(i) is supplied with a fifth selection signal (see FIGS. 5 and 6).

[0119] Configuration Example 2 of Pixel Circuit 530S(i,j) The pixel circuit 530S(i,j) includes a switch SW31, a switch SW32, a switch SW33, a transistor M31, a capacitor C31, and a node FD.

[0120] The switch SW31 has a first terminal electrically connected to the element 550S(i,j), a second terminal electrically connected to the node FD, and a function of controlling the conductive state or non-conductive state based on the potential of the conductive film TX(i).

[0121] The switch SW32 has a first terminal electrically connected to the node FD, a second terminal electrically connected to the conductive film VR, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film RS(i).

[0122] The capacitor C31 includes a conductive film electrically connected to the node FD and a conductive film electrically connected to the conductive film VCP.

[0123] The transistor M31 includes a gate electrode electrically connected to the node FD, and a first electrode electrically connected to the conductive film VPI.

[0124] The switch SW33 has a first terminal electrically connected to the second electrode of the transistor M31, a second terminal electrically connected to the conductive film WX(j), and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film SE(i).

[0125] As a result, the imaging signal generated by the element 550S(i,j) can be transferred to the node FD using the switch SW31. Alternatively, the imaging signal generated by the element 550S can be stored in the node FD using the switch SW31. Alternatively, the pixel circuit 530S and the element 550S can be put into a non-conductive state using the switch SW31. Alternatively, a correlated double sampling method can be applied. Alternatively, noise contained in the imaging signal can be reduced. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0126] <Configuration example 5 of function panel 700> The functional panel described in this embodiment has a read circuit RC(j), a conductive film VLEN, a conductive film VIV, and a conductive film CLL (see Figures 1A, 7A, 7B, and 12). Also, the functional panel of one embodiment of the present invention has a conductive film CAPSEL, a conductive film CDSBIAS, a conductive film CDSVDD, a conductive film CDSVSS, and a conductive film VCL.

[0127] 《Example of the configuration of readout circuit RC(j)》 The read circuit RC(j) includes an amplifier circuit and a sampling circuit SC(j).

[0128] <<Example of amplifier circuit configuration>> The amplifier circuit includes a transistor M32(j), which has a gate electrode electrically connected to the conductive film VLEN, a first electrode electrically connected to the conductive film WX(j), and a second electrode electrically connected to the conductive film VIV (see FIG. 7A).

[0129] When the switch SW33 is in a conductive state, the conductive film WX(j) connects the transistor M31 and the transistor M32(j) (see FIGS. 4 and 7A). This allows the transistor M31 and the transistor M32(j) to configure a source follower circuit. Alternatively, the potential of the conductive film WX(j) can be changed based on the potential of the node FD.

[0130] The sampling circuit SC(j) includes a first terminal IN(j), a second terminal, and a third terminal OUT(j) (see FIG. 7B), and also includes a node NS.

[0131] The first terminal IN(j) is electrically connected to the conductive film WX(j), the second terminal is electrically connected to the conductive film CLL, and the third terminal OUT(j) has the function of supplying a signal that changes based on the potential of the first terminal IN(j).

[0132] This makes it possible to obtain an imaging signal from the pixel circuit 530S(i,j). Or, for example, a correlated double sampling method can be applied. Or, a sampling circuit SC(j) can be provided for each conductive film WX(j). A differential signal of the pixel circuit 530S(i,j) can be obtained for each conductive film WX(j). Or, the operating frequency of the sampling circuit SC(j) can be suppressed. Or, noise can be reduced. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0133] <<Configuration Example 3 of Pixel 703(i,j)>> A plurality of pixels can be used for pixel 703(i,j). For example, a plurality of pixels that display colors with different hues can be used. Each of the plurality of pixels can be referred to as a sub-pixel. Alternatively, a set of a plurality of sub-pixels can be referred to as a pixel.

[0134] This allows the colors displayed by the multiple pixels to be mixed additively or subtractively, or allows colors of hues that cannot be displayed by individual pixels to be displayed.

[0135] Specifically, pixel 702B(i,j) displaying blue, pixel 702G(i,j) displaying green, and pixel 702R(i,j) displaying red can be used for pixel 703(i,j). Each of pixel 702B(i,j), pixel 702G(i,j), and pixel 702R(i,j) can be referred to as a sub-pixel (see FIG. 1B).

[0136] Also, for example, a pixel displaying white or the like can be used as pixel 703(i,j) in addition to the above set. Also, a pixel displaying cyan, a pixel displaying magenta, and a pixel displaying yellow can be used as pixel 703(i,j).

[0137] Also, for example, a pixel that emits infrared light can be added to the above set and used as pixel 703(i,j). Specifically, a pixel that emits light including light having a wavelength of 650 nm or more and 1000 nm or less can be used as pixel 703(i,j).

[0138] <Configuration example 6 of function panel 700> Another configuration of pixel circuit 530G(i,j) of the functional panel described in this embodiment will be described with reference to Figures 27, 28, and 29. Note that this differs from pixel circuit 530G(i,j) described with reference to Figures 3, 5, and 6 in that it includes a capacitance C21. 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.

[0139] Configuration Example 4 of Pixel Circuit 530G(i,j) The pixel circuit 530G(i,j) includes a node N21, a transistor M21, a switch SW21, a switch SW22, and a capacitor C21 (see FIG. 27). The pixel circuit 530G(i,j) also includes a node N22, a capacitor C22, and a switch SW23.

[0140] The transistor M21 includes a gate electrode electrically connected to the node N21, a first electrode electrically connected to the element 550G(i,j), and a second electrode electrically connected to the conductive film ANO.

[0141] The switch SW21 has a first terminal electrically connected to the conductive film S1g(j), a second terminal electrically connected to a node N21, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film G1(i).

[0142] The capacitor C21 has a first electrode electrically connected to the node N21.

[0143] The switch SW22 has a first terminal electrically connected to the conductive film S2g(j), a second terminal electrically connected to the second electrode of the capacitor C21, and a function of controlling a conductive state or a non-conductive state based on the potential of the conductive film G2(i).

[0144] In the first state ST1, the first node N21 holds a first voltage, in the second state ST2, the first node N21 holds a second voltage, and in the third state ST3, the first node N21 holds an image signal.

[0145] In addition, the drive circuit SD supplies a control signal including a first level and a second level, where the first level changes the node N21 from the third state ST3 to the first state ST1, and the second level changes the node N21 from the third state ST3 to the second state ST2.

[0146] For example, in order for the drive circuit SD to change the node N21 from the third state ST3 to the first state ST1 via the capacitor C21, it is necessary to determine and supply the first level in consideration of not only the potential of the node N21 in the first state ST1 but also the voltage held by the capacitor C21 in the third state ST3. Also, in order for the drive circuit SD to change the node N21 from the third state ST3 to the second state ST2 via the capacitor C21, it is necessary to determine and supply the second level in consideration of not only the potential of the node N21 in the second state ST2 but also the voltage held by the capacitor C21 in the third state ST3.

[0147] Specifically, a voltage (Vr-Vdata) obtained by subtracting the voltage Vdata already held by the capacitance C21 in the third state ST3 from a predetermined voltage Vr can be used for the first level. Alternatively, a voltage (Vrb-Vdata) obtained by subtracting the voltage Vdata already held by the capacitance C21 in the third state ST3 from a predetermined voltage Vrb can be used for the second level. Note that a predetermined voltage Vrb can be used for the second level, and a voltage (Vrb+Vdata) obtained by adding the voltage Vrb already held in the third state ST3 to the voltage Vrb can be used for the second state ST2.

[0148] Element 550G(i,j) changes brightness based on the potential at node N21.

[0149] Thereby, in the first state ST1, the pixel 702G(i,j) can be hidden, for example. Or, in the second state ST2, the pixel 702G(i,j) can be used for illumination. Or, in the third state ST3, the pixel 702G(i,j) can be used to display an image signal. Or, while switching the display of the pixel 702G(i,j) using the first selection signal and image signal, the pixel 702G(i,j) can be hidden or used for illumination using the second selection signal and control signal. Or, in the second state ST2, a high voltage can be supplied to the gate electrode of the transistor M21. Or, in the second state ST2, a large current can be supplied to the element 550G(i,j). As a result, a novel functional panel with excellent convenience, usefulness, or reliability can be provided.

[0150] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0151] (Embodiment 2) In this embodiment, a structure of a functional panel according to one embodiment of the present invention will be described with reference to FIGS.

[0152] Fig. 8 is a diagram for explaining the configuration of a functional panel according to one embodiment of the present invention, which is a cross-sectional view taken along lines X1-X2, X3-X4, X9-X10, and X11-X12 in Fig. 1A and a pair of pixels 703(i,j).

[0155] Fig. 11 is a diagram illustrating the configuration of a functional panel according to an embodiment of the present invention, Fig. 11A is a cross-sectional view taken along lines X1-X2 and X3-X4 in Fig. 1A, and Fig. 11B is a diagram illustrating a portion of Fig. 11A.

[0156] <Configuration example 1 of function panel 700> The functional panel described in this embodiment has a functional layer 520 (see FIG. 8).

[0157] Configuration example 1 of functional layer 520 The functional layer 520 includes a pixel circuit 530G(i,j) (see FIG. 8). The functional layer 520 includes, for example, a transistor M21 used in the pixel circuit 530G(i,j) (see FIGS. 3 and 9A).

[0158] The functional layer 520 includes an opening 591G. The pixel circuit 530G(i,j) is electrically connected to the element 550G(i,j) in the opening 591G (see FIGS. 8 and 9A).

[0159] <<Configuration Example 2 of Functional Layer 520>> The functional layer 520 includes a pixel circuit 530S(i,j) (see FIG. 8). The functional layer 520 includes, for example, a transistor used for the switch SW31 of the pixel circuit 530S(i,j) (see FIGS. 8 and 10A).

[0160] The functional layer 520 includes an opening 591S, and the pixel circuit 530S(i,j) is electrically connected to the element 550S(i,j) at the opening 591S (see FIGS. 8 and 10A).

[0161] This makes it possible to form pixel circuits 530G(i,j) in the functional layer 520. Or, it makes it possible to form pixel circuits 530S(i,j) in the functional layer 520. For example, it makes it possible to form a semiconductor film used in pixel circuit 530S(i,j) in the process of forming a semiconductor film used in pixel circuit 530G(i,j). Or, it makes it possible to simplify the manufacturing process. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0162] <Configuration example 3 of functional layer 520> The functional layer 520 includes a driving circuit GD (see FIGS. 1A and 8). The functional layer 520 includes, for example, a transistor MD used in the driving circuit GD (see FIGS. 8 and 11A).

[0163] The functional layer 520 comprises a driving circuit RD and a readout circuit RC (see FIG. 8).

[0164] As a result, for example, in the process of forming the semiconductor film used in the pixel circuit 530G(i,j), the semiconductor film used in the drive circuit GD can be formed. Or, for example, in the process of forming the semiconductor film used in the pixel circuit 530G(i,j), the semiconductor films used in the drive circuit RD and the readout circuit RC can be formed. Or, the manufacturing process of the functional panel can be simplified. As a result, it is possible to provide a novel functional panel that is highly convenient, useful, and reliable.

[0165] <<Example of transistor configuration>> A bottom-gate transistor or a top-gate transistor can be used for the functional layer 520. Specifically, the transistor can be used as a switch.

[0166] The transistor includes a semiconductor film 508, a conductive film 504, a conductive film 512A, and a conductive film 512B (see FIG. 9B).

[0167] 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.

[0168] The conductive film 504 has a region overlapping with the region 508C, and has a function of a gate electrode.

[0169] 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.

[0170] The conductive film 512A has either a function of a source electrode or a function of a drain electrode, and the conductive film 512B has the other function of a source electrode or a function of a drain electrode.

[0171] 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 524 and the conductive film 504. The conductive film 524 functions as a second gate electrode.

[0172] 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.

[0173] 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.

[0174] [Hydrogenated amorphous silicon] For example, hydrogenated amorphous silicon can be used for the semiconductor film 508. Alternatively, microcrystalline silicon or the like can be used for the semiconductor film 508. This makes it possible to provide a functional panel with less display unevenness than, for example, a functional panel using polysilicon for the semiconductor film 508. Alternatively, it is easy to increase the size of the functional panel.

[0175] [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.

[0176] Alternatively, for example, the reliability of the transistor can be improved as compared with a transistor in which hydrogenated amorphous silicon is used for the semiconductor film 508 .

[0177] Alternatively, the temperature required to manufacture the transistor can be made lower than that of a transistor using single crystal silicon, for example.

[0178] 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.

[0179] [Single crystal silicon] For example, single crystal silicon can be used for the semiconductor film 508. This allows for higher definition than, for example, a functional panel using hydrogenated amorphous silicon for the semiconductor film 508. Alternatively, for example, a functional panel with less display unevenness can be provided than, for example, a functional panel using polysilicon for the semiconductor film 508. Alternatively, for example, smart glasses or a head mounted display can be provided.

[0180] 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.

[0181] In addition, compared to a pixel circuit using a transistor with an amorphous silicon semiconductor film, the pixel circuit can hold an image signal for a longer period of time. 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. As a result, shooting can be performed using the global shutter method. In addition, a moving subject can be shot with reduced distortion.

[0182] For example, a transistor including an oxide semiconductor can be used. Specifically, an oxide semiconductor including indium, an oxide semiconductor including indium, gallium, and zinc, or an oxide semiconductor including indium, gallium, zinc, and tin can be used for a semiconductor film.

[0183] For example, a transistor having a smaller leakage current in an off state than a transistor using amorphous silicon for a semiconductor film can be used. Specifically, a transistor using an oxide semiconductor for a semiconductor film can be used as a switch or the like. This allows the potential of a floating node to be held for a longer time than a circuit using a transistor using amorphous silicon for a switch.

[0184] For example, a 25 nm thick film containing indium, gallium and zinc can be used for the semiconductor film 508 .

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] This makes it possible to suppress display flickering. Or, it makes it possible to reduce power consumption. Or, it makes it possible to display fast-moving videos smoothly. Or, it makes it possible to display photographs and the like with a rich range of gradations. As a result, it is possible to provide a novel functional panel that is excellent in convenience, usefulness, and reliability.

[0190] 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.

[0191] 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.

[0192] <Capacity configuration example> The capacitor includes a first conductive film, a second conductive film, and an insulating film, the insulating film having a region sandwiched between the first conductive film and the second conductive film.

[0193] For example, a conductive film used for a source electrode or a drain electrode of a transistor, a conductive film used for a gate electrode, and an insulating film used for a gate insulating film can be used as a capacitor.

[0194] <<Configuration Example 2 of Functional Layer 520>> The functional layer 520 includes an insulating film 521, an insulating film 518, an insulating film 516, an insulating film 506, an insulating film 501C, and the like (see FIGS. 9A and 9B).

[0195] The insulating film 521 has a region sandwiched between the pixel circuit 530G(i,j) and the element 550G(i,j).

[0196] The insulating film 518 has a region sandwiched between the insulating film 521 and the insulating film 501C.

[0197] The insulating film 516 has a region sandwiched between the insulating film 518 and the insulating film 501C.

[0198] The insulating film 506 has a region sandwiched between the insulating film 516 and the insulating film 501C.

[0199] [Insulating film 521] For example, the insulating film 521 can be made of an insulating inorganic material, an insulating organic material, or an insulating composite material containing an inorganic material and an organic material.

[0200] Specifically, the insulating film 521 can be formed using an inorganic oxide film, an inorganic nitride film, an inorganic oxynitride film, or the like, or a laminated material formed by stacking a plurality of films selected from these.

[0201] 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.

[0202] 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. Meanwhile, 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. For this reason, polyimide can be particularly suitably used for the insulating film 521, etc.

[0203] Alternatively, a photosensitive material may be used to form the insulating film 521. Specifically, the insulating film 521 can be a film formed using a photosensitive polyimide, a photosensitive acrylic resin, or the like.

[0204] This allows the insulating film 521 to flatten steps resulting from various structures overlapping with the insulating film 521, for example.

[0205] [Insulating film 518] For example, the material that can be used for the insulating film 521 can be used for the insulating film 518.

Specifically, a nitride insulating film can be used for the insulating film 518. For example, silicon nitride, silicon nitride oxide, aluminum nitride, aluminum nitride oxide, or the like can be used for the insulating film 518. This can suppress diffusion of impurities into the semiconductor film of the transistor.

[0207] [Insulating film 516] For example, the material that can be used for the insulating film 521 can be used for the insulating film 516 .

[0208] Specifically, the insulating film 516 can be formed using a method different from that of the insulating film 518.

[0211] [Insulating film 501D] The insulating film 501D has a region sandwiched between the insulating film 501C and the insulating film 516.

[0212] For example, the material that can be used for the insulating film 506 can be used for the insulating film 501D.

[0213] [Insulating film 501C] For example, the insulating film 501C can be made of a material that can be used for the insulating film 521. Specifically, the insulating film 501C can be made of a material containing silicon and oxygen. This can suppress diffusion of impurities into the pixel circuit, the first element, the second element, or the like.

[0214] <Configuration example 3 of functional layer 520> The functional layer 520 includes a conductive film, wiring, and terminals. A material having electrical conductivity can be used for the wiring, electrodes, terminals, conductive film, and the like.

[0215] [Wiring etc.] For example, inorganic conductive materials, organic conductive materials, metals, conductive ceramics, etc. can be used for wiring, etc.

[0216] Specifically, metal elements selected from aluminum, gold, platinum, silver, copper, chromium, tantalum, titanium, molybdenum, tungsten, nickel, iron, cobalt, palladium, and manganese can be used for wiring, etc. Alternatively, alloys containing the above-mentioned metal elements can be used for wiring, etc. In particular, an alloy of copper and manganese is suitable for microfabrication using a wet etching method.

[0217] Specifically, a two-layer structure in which a titanium film is laminated on an aluminum film, a two-layer structure in which a titanium film is laminated on a titanium nitride film, a two-layer structure in which a tungsten film is laminated on a titanium nitride film, a two-layer structure in which a tungsten film is laminated on a tantalum nitride film or a tungsten nitride film, and a three-layer structure in which a titanium film, an aluminum film is laminated on the titanium film, and a titanium film is further formed on top of that can be used for wiring, etc.

[0218] Specifically, conductive oxides such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, and zinc oxide doped with gallium can be used for wiring or the like.

[0219] Specifically, a film containing graphene or graphite can be used for wiring or the like.

[0220] For example, a film including graphene can be formed by forming a film including graphene oxide and reducing the film including graphene oxide. Examples of a reduction method include a method of applying heat and a method of using a reducing agent.

[0221] For example, a film containing metal nanowires can be used for wiring etc. Specifically, nanowires containing silver can be used.

[0222] Specifically, a conductive polymer can be used for wiring and the like.

[0223] For example, the terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material (see FIG. 8). Specifically, the terminal 519B can be electrically connected to the flexible printed circuit board FPC1 using a conductive material CP.

[0224] <Configuration example 7 of function panel 700> Moreover, functional panel 700 includes substrate 510, substrate 770, and sealing material 705 (see FIG. 9A). Functional panel 700 also includes structure KB.

[0225] 《Base material 510, base material 770》 A material having optical transparency can be used for the substrate 510 or the substrate 770 .

[0226] For example, a flexible material can be used for the substrate 510 or the substrate 770. This makes it possible to provide a flexible functional panel.

[0227] 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.

[0228] By the way, 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.

[0229] 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 .

[0230] 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 functional panel closer to the user. This can prevent the functional panel from being damaged or scratched during use.

[0231] 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.

[0232] 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.

[0233] For example, organic materials such as resin, resin film, or plastic can be used for the substrate 510 or substrate 770. Specifically, materials containing polyester, polyolefin, polyamide (nylon, aramid, etc.), polyimide, polycarbonate, polyurethane, acrylic resin, epoxy resin, or resin having a siloxane bond such as silicone can be used for the substrate 510 or substrate 770. For example, resin films, resin plates, laminated materials, etc. containing 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.

[0234] 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 .

[0235] 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.

[0236] 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.

[0237] Also, paper or wood may be used for the substrate 510 or substrate 770 .

[0238] 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.

[0239] 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.

[0240] "Sealing material 705" The sealing material 705 has an area sandwiched between the functional layer 520 and the base material 770, and has a function of bonding the functional layer 520 and the base material 770 together (see FIG. 9A).

[0241] The sealing material 705 can be an inorganic material, an organic material, or a composite material of an inorganic material and an organic material.

[0242] For example, the sealant 705 can be made of an organic material such as a heat-meltable resin or a curable resin.

[0243] 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.

[0244] 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.

[0245] 《Structure KB》 The structural body KB has a region sandwiched between the functional layer 520 and the base material 770. In addition, the structural body KB has a function of providing a predetermined gap between the functional layer 520 and the base material 770.

[0246] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0247] (Embodiment 3) In this embodiment, a structure of a functional panel according to one embodiment of the present invention will be described with reference to FIGS.

[0248] <Configuration example 1 of function panel 700> The functional panel 700 includes an element 550G(i,j) (see FIG. 9).

[0249] Configuration example 2 of element 550G(i,j) The electrode 551G(i,j), the electrode 552, and the layer 553G(j) containing a light-emitting material can be used for the element 550G(i,j). The layer 553G(j) containing a light-emitting material has a region sandwiched between the electrode 551G(i,j) and the electrode 552.

[0250] [Configuration example 1 of layer 553G(j) containing a luminescent material] For example, a laminate material can be used for layer 553G(j) that contains the luminescent material.

[0251] For example, blue light emitting material, green light emitting material, red light emitting material, infrared light emitting material, or ultraviolet light emitting material can be used for layer 553G(j) containing luminescent material.

[0252] [Configuration example 2 of layer 553G(j) containing a luminescent material] For example, a layer of material laminated to emit white light can be used for layer 553G(j) containing a light-emitting material.

[0253] Specifically, a plurality of materials that emit light of different hues can be used for layer 553G(j) containing a light-emitting material.

[0254] For example, a laminated material obtained by laminating a layer including a light-emitting material including a fluorescent material that emits blue light and a layer including a material other than the fluorescent material that emits green and red light can be used for the layer including the light-emitting material 553G(j). Alternatively, a laminated material obtained by laminating a layer including a light-emitting material including a fluorescent material that emits blue light and a layer including a material other than the fluorescent material that emits yellow light can be used for the layer including the light-emitting material 553G(j).

[0255] For example, a colored film CF(G) can be laminated on the layer 553G(j) containing a light-emitting material, which allows light of a predetermined hue to be extracted from white light.

[0256] [Configuration example 3 of layer 553G(j) containing a luminescent material] For example, a laminated material that is laminated so as to emit blue light or ultraviolet light can be used for the layer 553G(j) containing a light-emitting material. Also, for example, a color conversion layer can be used by being laminated.

[0257] [Configuration Example 4 of the layer 553G(j) containing a luminescent material] The layer 553G(j) containing a light-emitting material includes a light-emitting unit. The light-emitting unit includes one region where electrons injected from one side recombine with holes injected from the other side. The light-emitting unit includes a light-emitting material, and the light-emitting material emits energy generated by the recombination of electrons and holes as light. A hole transport layer and an electron transport layer can be used for the light-emitting unit. The hole transport layer is disposed closer to the positive electrode than the electron transport layer, and the hole transport layer has a higher hole mobility than the electron transport layer.

[0258] For example, a plurality of light-emitting units and an intermediate layer can be used in the layer 553G(j) containing a light-emitting material. The intermediate layer has a region sandwiched between two light-emitting units. The intermediate layer has a charge 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.

[0259] This makes it possible to increase the current efficiency relating to light emission, or to reduce the current density flowing through the light emitting element at the same luminance, or to increase the reliability of the light emitting element.

[0260] For example, a light-emitting unit including a material that emits light of one hue can be stacked with a light-emitting unit including a material that emits light of another hue to be used in the layer 553G(j) including the light-emitting material. Alternatively, a light-emitting unit including a material that emits light of one hue can be stacked with a light-emitting unit including a material that emits light of the same hue to be used in the layer 553G(j) including the light-emitting material. Specifically, two light-emitting units including a material that emits blue light can be stacked.

[0261] Incidentally, for example, high molecular weight compounds (oligomers, dendrimers, polymers, etc.), medium molecular weight compounds (compounds in the intermediate range between low molecular weight and high molecular weight: molecular weight 400 or more and 4000 or less), etc. can be used in layer 553G(j) containing a light-emitting material.

[0262] [Electrode 551G(i,j), electrode 552] For example, a material that can be used for a wiring or the like can be used for the electrode 551G(i,j) or the electrode 552. Specifically, a material that transmits visible light can be used for the electrode 551G(i,j) or the electrode 552.

[0263] 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.

[0264] For example, a metal film that transmits part of light and reflects the other part of light can be used for the electrode 551G(i,j) or the electrode 552. For example, a layer 553G(j) containing a light-emitting material is used to adjust the distance between the electrode 551G(i,j) and the electrode 552.

[0265] This allows a microresonator structure to be provided in element 550G(i,j). Alternatively, light of a specific wavelength can be extracted more efficiently than other light. Alternatively, light with a narrow half-width spectrum can be extracted. Alternatively, light of a vivid color can be extracted.

[0266] For example, a film that efficiently reflects light can be used for the electrode 551G(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.

[0267] Furthermore, the electrode 551G(i,j) is electrically connected to the pixel circuit 530G(i,j) through the opening 591G (see FIG. 10A). The electrode 551G(i,j) overlaps, for example, an opening formed in the insulating film 528, and the electrode 551G(i,j) has the insulating film 528 on its periphery.

[0268] This makes it possible to prevent a short circuit between electrode 551G(i,j) and electrode 552.

[0269] <<Configuration Example 2 of Element 550S(i,j)>> An element 550S(i,j) includes an electrode 551S(i,j), an electrode 552, and a layer 553S(j) including a photoelectric conversion material (see FIG. 10A).

[0270] For example, a heterojunction type photoelectric conversion element, a bulk heterojunction type photoelectric conversion element, or the like can be used for the element 550S(i,j).

[0271] [Configuration example 1 of layer 553S(j) containing photoelectric conversion material] For example, a laminated film in which a p-type semiconductor film and an n-type semiconductor film are laminated so as to be in contact with each other can be used for the layer 553S(j) containing a photoelectric conversion material. Note that an element 550S(i,j) using such a laminated film structure for the layer 553S(j) containing a photoelectric conversion material can be called a PN-type photodiode.

[0272] For example, a laminated film in which a p-type semiconductor film, an i-type semiconductor film, and an n-type semiconductor film are laminated so that an i-type semiconductor film is sandwiched between a p-type semiconductor film and an n-type semiconductor film can be used for the layer 553S(j) containing a photoelectric conversion material. Note that an element 550S(i,j) using a laminated film of such a structure for the layer 553S(j) containing a photoelectric conversion material can be called a PIN-type photodiode.

[0273] For example, a laminated film in which a p+ type semiconductor film, a p- type semiconductor film, a p type semiconductor film, and an n type semiconductor film are laminated so that a p- type semiconductor film is sandwiched between a p+ type semiconductor film and an n type semiconductor film, and a p type semiconductor film is sandwiched between the p- type semiconductor film and the n type semiconductor film, can be used for the layer 553S(j) containing a photoelectric conversion material. Note that an element 550S(i,j) using such a laminated film structure for the layer 553S(j) containing a photoelectric conversion material can be called an avalanche photodiode.

[0274] [Configuration example 2 of layer 553S(j) containing photoelectric conversion material] For example, a semiconductor containing a group 14 element can be used for the layer 553S(j) containing the photoelectric conversion material. Specifically, a semiconductor containing silicon can be used for the layer 553S(j) containing the photoelectric conversion material. For example, hydrogenated amorphous silicon, microcrystalline silicon, polysilicon, single crystal silicon, or the like can be used for the layer 553S(j) containing the photoelectric conversion material.

[0275] For example, an organic semiconductor can be used for the layer 553S(j) containing a photoelectric conversion material. Specifically, a part of a layer used for the layer 553G(j) containing a light-emitting material can be used for a part of the layer 553S(j) containing a photoelectric conversion material.

[0276] Specifically, a hole transport layer used in the layer 553G(j) containing a light-emitting material can be used in the layer 553S(j) containing a photoelectric conversion material. Alternatively, an electron transport layer used in the layer 553G(j) containing a light-emitting material can be used in the layer 553S(j) containing a photoelectric conversion material. Alternatively, a hole transport layer and an electron transport layer can be used in the layer 553S(j) containing a photoelectric conversion material.

[0277] Thereby, in the step of forming a hole-transport layer for the layer 553G(j) containing a light-emitting material, a hole-transport layer for the layer 553S(j) containing a photoelectric conversion material can be formed. Alternatively, in the step of forming an electron-transport layer for the layer 553G(j) containing a light-emitting material, an electron-transport layer for the layer 553S(j) containing a photoelectric conversion material can be formed. Alternatively, the manufacturing process can be simplified.

[0278] Also, for example, fullerenes (e.g., C 60 , C 70 An electron-accepting organic semiconductor material such as ZnO, ZnSe, etc. or a derivative thereof can be used for the n-type semiconductor film.

[0279] For example, a fullerene derivative dissolved or dispersed in the first solvent can be used for the layer 553S(i,j) including the photoelectric conversion material. Specifically, [6,6]-Phenyl-C71-butyric acid methyl ester (abbreviation: PC70BM), [6,6]-Phenyl-C61-butyric acid methyl ester (abbreviation: PC60BM), 1′,1″,4′,4″-Tetrahydro-di[1,4]methanonaphthaleno[1,2:2′,3′,56,60:2″,3″][5,6]fullerene-C60 (abbreviation: ICBA), or the like can be used for the layer 553S(i,j) including the photoelectric conversion material.

[0280] Furthermore, for example, an electron-donating organic semiconductor material such as copper(II) phthalocyanine (CuPc) or tetraphenyldibenzoperiflanthene (DBP) can be used for the p-type semiconductor film.

[0281] For example, a π-conjugated organic polymer material, oligomer, or low molecular weight material that is dissolved or dispersed in the first solvent can be used for the layer 553S(i,j) containing the photoelectric conversion material. Specifically, a polyphenylenevinylene-based material or a polythiophene-based material can be used for the layer 553S(i,j) containing the photoelectric conversion material. Specifically, Poly([2,6′-4,8-di(5-ethylhexylthienyl)benzo[1,2-b;3,3-b]dithiophene]{3-fluoro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (abbreviation: PTB7-Th), Poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (abbreviation: PYB7), Poly(3-hexylthiophene-2,5-diyl) (abbreviation: P3HT), or the like can be used for the layer 553S(i,j) containing a photoelectric conversion material.

[0282] Also, for example, a film obtained by co-evaporating an electron-accepting semiconductor material and an electron-donating semiconductor material can be used as the i-type semiconductor film.

[0283] <Configuration example 2 of function panel 700> The functional panel 700 includes an insulating film 528 and an insulating film 573 (see FIG. 9A).

[0284] "Insulating Film 528" The insulating film 528 has a region sandwiched between the functional layer 520 and the base material 770, and the insulating film 528 has an opening in a region overlapping with the element 550G(i,j) (see FIG. 9A).

[0285] For example, the same material as that 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.

[0286] "Insulating Film 573" The insulating film 573 has a region that sandwiches the element 550G(i,j) between itself and the functional layer 520 (see FIG. 9A).

[0287] For example, a single film or a stacked film in which a plurality of films are stacked can be used for the insulating film 573. Specifically, a stacked film in which an insulating film 573A that can be formed by a method that does not damage the element 550G(i,j) and a dense insulating film 573B with few defects are stacked can be used for the insulating film 573.

[0288] This can suppress the diffusion of impurities into the element 550G(i,j), or can improve the reliability of the element 550G(i,j).

[0289] <Configuration example 3 of function panel 700> The functional panel 700 includes a functional layer 720 (see FIG. 9A).

[0290] <Functional Layer 720> The functional layer 720 includes a light-shielding film BM, a colored film CF(G), and an insulating film 771. A color conversion layer can also be used.

[0291] 《Light blocking film BM》 The light-shielding film BM has an opening in a region overlapping with the pixel 702G(i,j). The light-shielding film BM also has an opening in a region overlapping with the pixel 702S(i,j).

[0292] For example, a dark color material can be used for the light shielding film BM, which can improve the display contrast.

[0293] 《Colored film CF(G)》 The colored film CF(G) has an area sandwiched between the base material 770 and the element 550G(i,j). For example, a material that selectively transmits light of a predetermined color can be used for the colored film CF(G). Specifically, a material that transmits red light, green light, or blue light can be used for the colored film CF(G).

[0294] <<Example of the configuration of the insulating film 771>> The insulating film 771 has a region sandwiched between the base material 770 and the element 550G(i,j).

[0295] The insulating film 771 has an area that sandwiches the light-shielding film BM, the colored film CF(G), or the color conversion layer between itself and the base material 770. This makes it possible to flatten unevenness resulting from the thickness of the light-shielding film BM, the colored film CF(G), or the color conversion layer.

[0296] Color conversion layer The color conversion layer comprises a region sandwiched between substrate 770 and element 550G(i,j).

[0297] For example, a material that emits light having a wavelength longer than the wavelength of the incident light can be used for the color conversion layer. For example, a material that absorbs blue light or ultraviolet light and converts it to green light and emits it, a material that absorbs blue light or ultraviolet light and converts it to red light and emits it, or a material that absorbs ultraviolet light and converts it to blue light and emits it can be used for the color conversion layer. 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.

[0298] <Configuration example 4 of function panel 700> The functional panel 700 includes a light-shielding film KBM (see FIG. 9A).

[0299] 《Light blocking film KBM》 The light-shielding film KBM has an opening in a region overlapping with the pixel 702S(i,j). The light-shielding film KBM also has a region sandwiched between the functional layer 520 and the base material 770, and has a function of providing a predetermined gap between the functional layer 520 and the base material 770. For example, a dark-colored material can be used for the light-shielding film KBM. This makes it possible to suppress stray light from entering the pixel 702S(i,j).

[0300] <Configuration example 5 of function panel 700> The functional panel 700 includes a functional film 770P (see FIG. 9A).

[0301] 《Functional membrane 770P, etc.》 The functional film 770P has an area that overlaps with the element 550G(i,j).

[0302] 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.

[0303] 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.

[0304] For example, a circularly polarizing film can be used for the functional film 770P.

[0305] In addition, the functional film 770P can be used with antistatic films that prevent dust from sticking, water-repellent films that make it difficult for dirt to adhere, oil-repellent films that make it difficult for dirt to adhere, anti-reflection films, non-glossy films (anti-glare films), hard coat films that prevent scratches from occurring during use, and self-repairing films that repair any scratches that do occur.

[0306] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0307] (Embodiment 4) In this embodiment, a structure of a functional panel according to one embodiment of the present invention will be described with reference to FIGS.

[0309] Fig. 13 is a diagram illustrating a configuration of a functional panel according to one embodiment of the present invention, Fig. 13A is a schematic diagram illustrating an arrangement of pixels included in the functional panel according to one embodiment of the present invention, and Fig. 13B is a diagram illustrating a part of Fig. 13A.

[0310] Fig. 14 is a diagram for explaining the configuration of a functional panel according to one embodiment of the present invention. Fig. 14A is a diagram for explaining a part of Fig. 13A, Fig. 14B is a diagram for explaining a part of Fig. 14A, and Fig. 14C is a diagram for explaining another part of Fig. 14A. Fig. 14D is a circuit diagram for explaining the configuration of a pixel circuit.

[0311] <Configuration example 1 of function panel 700> The functional panel 700 described in this embodiment has an area 231 (see FIG. 12).

[0312] <<Configuration Example 1 of Area 231>> The region 231 comprises a group of pixels 703(i,1) through 703(i,n) and another group of pixels 703(1,j) through 703(m,j).

[0313] A group of a set of pixels 703(i,1) to a set of pixels 703(i,n) are arranged in the row direction (the direction indicated by arrow R1 in the figure), and the group of a set of pixels 703(i,1) to a set of pixels 703(i,n) includes the set of pixels 703(i,j).

[0314] In addition, a group of pixels 703(i,1) to 703(i,n) are electrically connected to a conductive film G1(i).

[0315] Another group of a set of pixels 703(1,j) through a set of pixels 703(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 a set of pixels 703(1,j) through a set of pixels 703(m,j) includes a set of pixels 703(i,j).

[0316] Another group of a set of pixels 703(1,j) to a set of pixels 703(m,j) are electrically connected to the conductive film S1g(j).

[0317] This makes it possible to obtain imaging information from a plurality of pixels, or to supply image information to a plurality of pixels, thereby providing a novel functional panel that is highly convenient, useful, and reliable.

[0318] <<Configuration Example 2 of Area 231>> Another configuration of region 231 of a functional panel according to an embodiment of the present invention will be described with reference to Figs. 12, 13, and 14. Note that this configuration is different from configuration example 1 of region 231 in that pixel 703(i+1,j) has a different configuration from pixel 703(i,j). Specifically, pixel circuit 530G(i+1,j) has a different configuration from pixel circuit 530G(i,j). Here, the different parts will be described in detail, and the above description will be used for parts in which a similar configuration can be used.

[0319] The region 231 comprises a group of pixels 703(i,1) through 703(i,n) and another group of pixels 703(1,j) through 703(m,j) (see FIG. 12).

[0320] The group of set of pixels 703(i,1) through set of pixels 703(i,n) includes a set of pixels 703(i,j) and a set of pixels 703(i,j+1) (see Figures 13A and 13B).

[0321] Another group of a set of pixels 703(1,j) to a set of pixels 703(m,j) includes a set of pixels 703(i,j) and a set of pixels 703(i+1,j) (see Figures 13A and 13B).

[0322] The set of pixels 703(i+1,j) includes pixel 702G(i+1,j), which includes pixel circuit 530G(i+1,j) (see Figures 13B and 14A). For example, the circuit shown in Figure 14D can be used for pixel circuit 530G(i+1,j).

[0323] This allows the pixel circuit 530G(i+1,j) to hold the third state ST3 regardless of the second selection signal. Or, for example, the potential of the node N21 of the pixel circuit 530G(i+1,j) is not affected by the second selection signal. Or, pixels that are not affected by the second selection signal can be arranged between pixels that obtain a control signal based on the second selection signal. Or, the pixels that obtain a control signal can be arranged at appropriate intervals in the region 231.

[0324] <Configuration example 2 of function panel 700> Moreover, a functional panel 700 according to an embodiment of the present invention includes a multiplexer MUX, an amplifier circuit AMP, and an analog-to-digital conversion circuit ADC (see FIG. 12).

[0325] <<Example of multiplexer MUX configuration>> The multiplexer MUX has a function of selecting one of the multiple sampling circuits SC to obtain an image signal and supplying it to, for example, an amplifier circuit AMP.

[0326] For example, the multiplexer MUX is electrically connected to the third terminal OUT(j) of the sampling circuit SC(j) (see FIG. 7B). Specifically, the multiplexer MUX is electrically connected to the sampling circuits SC(1) to SC(9) and can obtain imaging signals from a given sampling circuit and supply them to the amplifier circuit AMP.

[0327] This makes it possible to acquire imaging information by selecting a predetermined pixel from a plurality of pixels arranged in the row direction. Alternatively, the number of imaging signals acquired simultaneously can be suppressed to a predetermined number. Alternatively, an analog-to-digital conversion circuit ADC having a smaller number of input channels than the number of pixels arranged in the row direction can be used. As a result, a novel functional panel that is excellent in convenience, usefulness, and reliability can be provided.

[0328] Example of amplifier circuit AMP configuration The amplifier circuit AMP can amplify the image signal and supply it to the analog-to-digital conversion circuit ADC.

[0329] The functional layer 520 includes a multiplexer MUX and an amplifier circuit AMP.

[0330] This makes it possible to form a semiconductor film used in the multiplexer MUX and the amplifier circuit AMP in the process of forming a semiconductor film used in the pixel circuit 530G(i,j), for example. Alternatively, the manufacturing process of the functional panel can be simplified. As a result, a novel functional panel with excellent convenience, usefulness, and reliability can be provided.

[0331] Example of analog-to-digital conversion circuit ADC configuration The analog-to-digital conversion circuit ADC has a function of converting an analog image signal into a digital signal, thereby making it possible to suppress degradation of the image signal caused by transmission.

[0332] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0333] (Embodiment 5) In this embodiment, a structure of a display device according to one embodiment of the present invention will be described with reference to FIG.

[0334] 15A to 15D are perspective views illustrating the appearance of the display device of one embodiment of the present invention.

[0335] <Example of display device configuration> The display device described in this embodiment has a control unit 238 and a functional panel 700 (see FIG. 15A).

[0336] Configuration example 1 of the control unit 238 The control unit 238 is supplied with image information VI and control information CI, which may be, for example, a clock signal or a timing signal.

[0337] The control unit 238 generates information based on the image information VI, and generates a control signal based on the control information CI, and also provides the information and the control signal.

[0338] For example, the information includes a gradation of 8 bits or more, preferably 12 bits or more. Also, for example, a clock signal or a start pulse of a shift register used in a driving circuit can be used as a control signal.

[0339] <<Configuration Example 2 of the Control Unit 238>> For example, the decompression circuit 234 and the image processing circuit 235 can be used in the control unit 238 .

[0340] 《Extension circuit 234》 The decompression circuit 234 has a function of decompressing the image information VI that is supplied in a compressed state. The decompression circuit 234 has a storage unit. The storage unit has a function of storing, for example, the decompressed image information.

[0341] "Image processing circuit 235" The image processing circuit 235 includes, for example, a storage area. The storage area has a function of storing information included in the image information VI, for example.

[0342] The image processing circuit 235 has, for example, a function of correcting the image information VI based on a predetermined characteristic curve to generate information, and a function of supplying the information.

[0343] <<Configuration example 1 of function panel 700>> Information and control signals are supplied to the functional panel 700. For example, the functional panel 700 described in any one of the first to fourth embodiments can be used.

[0344] <<Configuration Example 3 of Pixel 703(i,j)>> Pixel 703(i,j) is displayed based on the information.

[0345] This allows the image information VI to be displayed using the first element 550G(i,j). As a result, a novel display device with excellent convenience, usefulness, or reliability can be provided. Or, for example, an information device terminal (see FIG. 15B), a video display system (see FIG. 15C), or a computer (see FIG. 15D) can be provided.

[0346] <<Function panel configuration example 2>> For example, the functional panel 700 includes a driving circuit and a control circuit.

[0347] <Drive circuit> The drive circuits operate based on control signals, which can be used to synchronize the operation of multiple drive circuits (see FIG. 15A).

[0348] For example, the driving circuit GD can be used in the functional panel 700. The driving circuit GD is supplied with a control signal and has a function of supplying a first selection signal.

[0349] Also, for example, the driving circuit SD can be used in the functional panel 700. The driving circuit SD is supplied with control signals and information and can supply image signals.

[0350] Also, for example, the driver circuit RD can be used in the functional panel 700. The driver circuit RD is supplied with a control signal and can supply the third to fifth selection signals.

[0351] Also, for example, a readout circuit RC can be used in the functional panel 700. The readout circuit RC is supplied with a control signal and can read out an image signal using, for example, a correlated double sampling method.

[0352] Control Circuit The control circuit has a function of generating and supplying a control signal, which may be, for example, a clock signal or a timing signal.

[0353] Specifically, a control circuit formed on a rigid substrate can be used for the functional panel, or a flexible printed circuit board can be used to electrically connect the control circuit formed on the rigid substrate and the control unit 238.

[0354] For example, a timing controller can be used for the control circuit 233. Also, a control circuit 243 can be used to synchronize the operation of the drive circuit RD and the read circuit RC.

[0355] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0356] (Embodiment 6) In this embodiment, a structure of an input / output device of one embodiment of the present invention will be described with reference to FIGS.

[0357] FIG. 16 is a block diagram illustrating a configuration of an input / output device of one embodiment of the present invention.

[0358] Fig. 17 is a diagram illustrating the configuration of an input / output device according to one embodiment of the present invention. Fig. 17A is a perspective view of the input / output device according to one embodiment of the present invention, Fig. 17B and Fig. 17C are cross-sectional views illustrating a part of Fig. 17A, and Fig. 17D is an electrical resistance-stress curve that diagrammatically illustrates the characteristics of a detector.

[0359] Fig. 18 is a diagram illustrating a configuration of an input / output device according to one embodiment of the present invention. Fig. 18A is a perspective view of a member used in the input / output device according to one embodiment of the present invention, Fig. 18B and Fig. 18C are cross-sectional views illustrating a part of Fig. 17A, and Fig. 18D is a stress-strain curve that illustrates the characteristics of a structure that undergoes snap-through buckling.

[0360] <Example 1 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. 16).

[0361] Configuration Example 1 of Display Unit 230 The display unit 230 includes a functional panel 700. For example, the functional panel 700 described in any one of the first to fourth embodiments can be used for the display unit 230. Note that a configuration having the input unit 240 and the display unit 230 can be referred to as a functional panel 700TP.

[0362] Configuration example 1 of the input unit 240 The input section 240 has a detection area 241, the input section 240 detects an object close to the detection area 241, and the detection area 241 has an area overlapping with the pixel 703(i,j).

[0363] This makes it possible to detect an object approaching an area overlapping with the display unit 230 while displaying image information using the display unit 230. Alternatively, position information can be input using a finger or the like that is brought close to the display unit 230 as a pointer. Alternatively, position information can be associated with image information displayed on the display unit 230. As a result, it is possible to provide a novel input / output device that is highly convenient, useful, and reliable.

[0364] Configuration example 1 of detection area 241 The sensing area 241 may, for example, include one or more detectors.

[0365] The detection region 241 has a group of detectors 802(g,1) through 802(g,q) and another group of detectors 802(1,h) through 802(p,h), where g is an integer between 1 and p, h is an integer between 1 and q, and p and q are integers greater than or equal to 1.

[0366] A group of detectors 802(g,1) to 802(g,q) including a detector 802(g,h) are arranged in the row direction (the direction indicated by the arrow R2 in the figure) and are electrically connected to the conductive film CL(g). Note that the direction indicated by the arrow R2 may be the same as or different from the direction indicated by the arrow R1.

[0367] In addition, another group of detectors 802(1,h) to 802(p,h), including detector 802(g,h), are arranged in a column direction (the direction indicated by arrow C2 in the figure) that intersects with the row direction, and are electrically connected to wiring ML(h).

[0368] Detector The detector has a function of detecting a nearby pointer. For example, a finger or a stylus pen can be used as the pointer. For example, a metal piece or a coil can be used as the stylus pen.

[0369] Specifically, a capacitance type proximity sensor, an electromagnetic induction type proximity sensor, an optical type proximity sensor, a resistive film type proximity sensor, or the like can be used as the detector.

[0370] Furthermore, detectors of multiple types can be used in combination. For example, a detector for detecting a finger and a detector for detecting a stylus pen can be used in combination.

[0371] 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.

[0372] Specifically, a finger can be detected using a capacitance type, a pressure sensitive type, or an optical type proximity sensor, or a stylus pen can be detected using an electromagnetic induction type or an optical type proximity sensor.

[0373] Configuration example 2 of input unit 240 The input section 240 comprises an oscillator circuit OSC and a detection circuit DC (see FIG. 16).

[0374] The oscillator circuit OSC supplies a search signal to the detector 802(g,h). For example, a square wave, a sawtooth wave, a triangular wave, a sine wave, etc. can be used as the search signal.

[0375] The detector 802(g,h) generates and provides a detection signal that varies based on the distance to the pointer proximate to the detector 802(g,h) and the probe signal.

[0376] The detection circuit DC provides input information based on the detection signal.

[0377] This makes it possible to detect the distance from the approaching pointer to the detection area 241. Alternatively, it makes it possible to detect the position within the detection area 241 to which the pointer is closest.

[0378] Detector configuration example 1 Area 231 is disposed on the side closer to the pointer than detection area 241, and area 231 is flexible (see FIGS. 17A and 17B). Also, for example, an image showing the layout of a keyboard can be displayed in area 231 (see FIG. 17A).

[0379] Detector configuration example 2 The detector 802(g,h) has a function of detecting the amount of depression, and the detector 802(g,h) detects the pointer via the area 231 (see FIG. 17B).

[0380] For example, the detector 802(g,h) detects the amount by which a pointer is pressed toward the detector 802(g,h). Specifically, the detector 802(g,h) detects the amount by which a finger or a stylus pen is pressed from a plane including the area 231 toward a plane including the detection area 241 (see FIG. 17C).

[0381] For example, a pressure sensor can be used for the detector 802(g,h). Specifically, an element whose electrical resistance changes depending on pressure can be used for the detector 802(g,h) (see FIG. 17D). This allows the detector 802(g,h) to detect the amount of depression.

[0382] <Example 2 of I / O device configuration> The input / output device described in this embodiment also includes a member 249 (see FIG. 17A and FIGS. 18A to 18C).

[0383] 《Example of the configuration of component 249》 The member 249 overlaps the sensing region 241 and has elasticity.

[0384] For example, an elastic body can be used for the member 249. Specifically, a spring, a leaf spring, rubber, sponge, or the like can be used.

[0385] This allows the detector 802(g,h) to detect the amount of depression, or allows the user to feel the force corresponding to the amount of depression of the pointer.

[0386] Also, for example, a structure that undergoes snap buckling can be used for the member 249. Specifically, a dome-shaped structure or the like can be used for the member 249 (see FIG. 18B).

[0387] The member 249 has a mode mode1 that is stable in a region where the strain ε is small, and a mode mode2 that is stable in a region where the strain ε is large (see Figs. 18C and 18D). At the buckling point, the member 249 jumps from mode mode1 to mode mode2 (see Fig. 18D). By removing the strain, the member 249 reversibly jumps from mode mode2 to mode mode1.

[0388] This allows the detector 802(g,h) to detect a force corresponding to the amount of pushing up to the buckling point. Or the user can feel the force. Or when the buckling point is exceeded, the user can feel a click. Or a so-called tactile switch can be provided. Or, when the user releases the pointer that he or she has pushed, the structure that performs the snap buckling can return to the original mode.

[0389] In addition, a detection area 241 can be provided so as to overlap the structure that performs snap buckling, and an area 231 can be provided so as to overlap the detection area 241, and an image used for operation can be displayed at a position that overlaps with the structure that performs snap buckling. For example, a layout that is suitable for a keyboard can be used for the layout of the structure that performs snap buckling. Or, a layout that is suitable for a home button can be used for the layout of the structure that performs snap buckling.

[0390] This allows the user to press in the image to be used for the displayed operation, or allows the user to feel a clicking sensation when the image is pressed.

[0391] Alternatively, a member 249 can be used that includes an area in which a plurality of structures that perform snap-through buckling are provided over the entire surface. A detection area 241 is provided overlapping the area, and an area 231 is provided overlapping the detection area 241, and an image used for operation can be displayed at a position that overlaps with the area in which the structures are provided over the entire surface.

[0392] This allows images to be freely arranged for use in operations that provide a clicking sensation when pressed.

[0393] The detection unit 250 may be disposed on top of the input / output device described in this embodiment. For example, a pressure-sensitive switch may be used for the detection unit 250. Specifically, a conductive material may be used for a dome-shaped structure that undergoes snap buckling, and the dome-shaped structure may be used for the contacts of the pressure-sensitive switch. This allows a so-called membrane switch to be provided. Alternatively, a switch with a clicking sensation may be provided. Alternatively, a so-called tactile switch may be provided.

[0394] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0401] <Configuration example 1 of information processing device> The information processing device described in this embodiment includes an arithmetic unit 210 and an input / output unit 220 (see FIG. 19A). The input / output unit 220 is electrically connected to the arithmetic unit 210. The information processing device 200 may include a housing (see FIGS. 19B and 19C).

[0402] Configuration Example 1 of the Calculation Device 210 The arithmetic unit 210 is supplied with input information II or sensed information DS. The arithmetic unit 210 generates control information CI and image information VI based on the input information II or sensed information DS, and supplies the control information CI and image information VI.

[0403] 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.

[0404] The transmission path 214 is electrically connected to the calculation unit 211 , the storage unit 212 , and the input / output interface 215 .

[0405] 《Arithmetic unit 211》 The calculation unit 211 has a function of executing a program, for example.

[0406] 《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.

[0407] Specifically, a hard disk, a flash memory, a memory including a transistor including an oxide semiconductor, or the like can be used.

[0408] 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.

[0409] 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.

[0410] Example of the configuration of the input / output device 220 An input / output device 220 provides input information II and sensed information DS, and the input / output device 220 is provided with control information CI and image information VI (see FIG. 19A).

[0411] 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.

[0412] For example, a signal for controlling the luminance, saturation, or hue of the image information VI may be used as the control information CI, or a signal for changing the display of a part of the image information VI may be used as the control information CI.

[0413] 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 sixth embodiment can be used for the input / output device 220. The input / output device 220 can also include a communication unit 290.

[0414] Configuration example of display unit 230 The display unit 230 displays the image information VI based on the control information CI. For example, the display device described in the fifth embodiment can be used for the display unit 230.

[0415] 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.

[0416] For example, a human interface or the like can be used for the input unit 240 (see FIG. 19A). Specifically, a keyboard, a mouse, a touch sensor, a microphone, a camera, or the like can be used for the input unit 240.

[0417] 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.

[0418] 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.

[0419] 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.

[0420] 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.

[0421] The user can also provide a "drag command" to pull out and display the navigation panel NP to the edge of the display area of ​​the display unit 230 by using a gesture of moving a finger in contact with the edge of the display area (see FIG. 19C). The user can also provide a "leaf-through command" to flip through the index image IND, parts of other pages, or thumbnail images TN of other pages in a predetermined order on the navigation panel NP by using a gesture of moving the position where the finger is pressed firmly, or by using the pressure of the finger. This allows the pages of an electronic book to be turned as if flipping through the pages of a paper book. Or, the user can search for a predetermined page by relying on the thumbnail image TN or index image IND.

[0422] 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.

[0423] 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.

[0424] For example, the detection unit 250 may use a photodetector, a posture detector, an acceleration sensor, a direction sensor, a GPS (Global Positioning System) signal receiving circuit, a pressure-sensitive switch, a pressure sensor, a temperature sensor, a humidity sensor, a camera, or the like.

[0425] 《Communication Section 290》 The communication unit 290 has a function of supplying information to the network and acquiring information from the network.

[0426] 《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.

[0427] This makes it possible to generate control information CI based on input information II or detection information DS. Or, it is possible to display image information VI based on input information II or detection information DS. 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 excellent in convenience, usefulness, and reliability.

[0428] In addition, these components cannot be clearly separated, and one component may serve as another component or may include a part of another component. For example, a touch panel in which a touch sensor is superimposed on a functional panel serves as both a display unit and an input unit.

[0429] Configuration Example 2 of the Calculation Device 210 The computing device 210 includes an artificial intelligence unit 213 (see FIG. 19A).

[0430] The artificial intelligence unit 213 is supplied with the input information II or the sensed information DS, and infers the control information CI based on the input information II or the sensed information DS. The artificial intelligence unit 213 also supplies the control information CI.

[0431] This makes it possible to generate control information CI that is displayed in a way that is perceived as suitable. Or, it is possible to display control information CI that is displayed in a way that is perceived as suitable. Or, it is possible to generate control information CI that is displayed in a way that is perceived as comfortable. Or, it is possible to display control information CI that is displayed in a way that is perceived as comfortable. As a result, it is possible to provide a novel information processing device that is excellent in convenience, usefulness, and reliability.

[0432] [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.

[0433] Specifically, the artificial intelligence unit 213 can perform natural language processing on the input information II to extract some words contained in 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 and use control information CI that displays the extracted part in a color, pattern, font, or the like that is different from the other parts.

[0434] [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.

[0435] 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.

[0436] [Inference using detection information DS] Specifically, the artificial intelligence unit 213 can generate an inference RI 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.

[0437] 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.

[0438] 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 included in the input unit 240 can be used as the control information CI.

[0439] <Configuration example 2 of information processing device> Another configuration of the information processing device of one embodiment of the present invention will be described with reference to FIGS. 20A and 20B.

[0440] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 20A).

[0441] [First step] In the first step, the settings are initialized (see FIG. 20A (S1)).

[0442] 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.

[0443] [Second step] In the second step, interrupt processing is permitted (see FIG. 20A (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.

[0444] 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.

[0445] [Third step] In the 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. 20A (S3)). Note that the predetermined mode specifies the mode in which the image 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 VI.

[0446] For example, one way of displaying the image information VI may be associated with a first mode, and another way of displaying the image information VI may be associated with a second mode, allowing the display method to be selected based on the selected mode.

[0447] 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.

[0448] 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.

[0449] 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.

[0450] 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.

[0451] 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.

[0452] 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.

[0453] 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.

[0454] [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. 20A (S4)).

[0455] For example, the end command supplied in the interrupt process may be used for the judgment.

[0456] [5th ​​step] In the fifth step, the process ends (see FIG. 20A (S5)).

[0457] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 20B).

[0458] [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. 20B (S6)). Note that instead of the illuminance of the environment, the color temperature or chromaticity of the ambient light may be detected.

[0459] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (see FIG. 20B (S7)). For example, the brightness of the display is determined so as not to be too dark or too bright.

[0460] 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.

[0461] [8th step] In the eighth step, the interrupt process ends (see FIG. 20B (S8)).

[0462] <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.

[0463] Fig. 21A is a flowchart illustrating a program according to one embodiment of the present invention, which is a flowchart illustrating an interrupt process different from the interrupt process shown in Fig. 20B.

[0464] Note that the configuration example 3 of the information processing device differs from the interrupt processing described with reference to Fig. 20B in that the interrupt processing includes a step of changing the mode based on a supplied predetermined event. 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.

[0465] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 21A).

[0466] [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. 21A (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.

[0467] [Seventh step] In the seventh step, the mode is changed (see FIG. 21A (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.

[0468] 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. 21B).

[0469] 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. 21B and 21C). 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.

[0470] 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 conductive films G2(m+1) to G2(2m) based on the signals GCLK, PWC1, and PWC2.

[0471] 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.

[0472] [8th step] In the eighth step, the interrupt process is ended (see FIG. 21A (U8)). Note that the interrupt process may be repeatedly executed during the execution of the main process.

[0473] 《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.

[0474] 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.

[0475] 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.

[0476] 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 .

[0477] Commands associated with specific events For example, the termination command may be associated with a certain event.

[0478] 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.

[0479] For example, a "scroll command" that moves the display position of a part of an image information and displays another part that is continuous with the part can be associated with a specific event. Note that an argument that determines the speed at which the display position is moved when the "scroll command" is executed can be given using the specific event.

[0480] 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.

[0481] 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.

[0482] The presence or absence of qualification to obtain information may be determined using location information detected by the detection unit 250. Specifically, when the user is inside or in an area of ​​a specific classroom, school, conference room, company, building, etc., it may be determined that the user is qualified to obtain information. This allows the information processing device 200 to receive educational materials distributed in a classroom of a school or university, for example, and use the information processing device 200 as a textbook, etc. (see FIG. 19C). Alternatively, materials distributed in a conference room of a company, etc. may be received and used as conference materials.

[0483] <Configuration example 4 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0484] Note that the configuration example 4 of the information processing device described with reference to Fig. 22A differs from the configuration example described with reference to Fig. 20B in the interrupt processing. Specifically, the interrupt processing includes a step of identifying an area, a step of generating an image, a step of displaying the image, and a step of capturing an image based on a given event supplied. Here, the different parts are described in detail, and the above description is used for parts that can use a similar configuration.

[0485] <<Interrupt Processing>> The interrupt process comprises a sixth step to an eleventh step (see FIG. 22A).

[0486] [Sixth step] In the sixth step, if the predetermined event is supplied, the process proceeds to a seventh step, and if the predetermined event is not supplied, the process proceeds to an eleventh step (see FIG. 22A (V6)).

[0487] For example, a predetermined event can be supplied using the detection unit 250. Specifically, a motion such as lifting the information processing device can be used as the predetermined event. For example, an angular acceleration sensor or an acceleration sensor can be used to detect the motion of the information processing device. Alternatively, a touch sensor can be used to detect contact with a finger or the like or the proximity of a subject.

[0488] [Seventh step] In the seventh step, the first region SH is identified (see FIG. 22A (V7)).

[0489] For example, a region in contact with or close to a subject such as a finger on the input / output device 220 of one embodiment of the present invention can be the first region SH. Alternatively, a region set in advance by a user or the like can be used as the first region SH.

[0490] Specifically, a finger THM or the like that is in contact with or in proximity to a functional panel of one embodiment of the present invention can be photographed using pixel 703(i,j), and the image can be processed to identify the first area SH (see FIG. 22B).

[0491] For example, a shadow created by the contact or proximity of a subject such as a finger THM blocking external light can be captured using pixel 703(i,j) of a functional panel according to one embodiment of the present invention, and the image can be processed to identify the first area SH.

[0492] Alternatively, pixel 703(i,j) of a functional panel according to one embodiment of the present invention can be used to irradiate light onto an object such as a finger THM that is in contact with or in close proximity, and the light reflected by the object can be captured using pixel 703(i,j), and the image can be processed to identify the first region SH.

[0493] Alternatively, a touch sensor can be used to identify an area touched by a subject such as a finger THM as the first area SH.

[0494] [8th step] In the eighth step, an image FI including a second region and a third region is generated based on the first region SH (see FIG. 22A (V8) and FIG. 22B). For example, the shape of the first region SH is used as the shape of the second region, and the region excluding the first region SH is used as the third region.

[0495] [9th step] In a ninth step, the image FI is displayed such that the second region overlaps the first region SH (see FIG. 22A (V9) and FIG. 22B).

[0496] For example, an image signal is generated from an image FI and supplied to the region 231, and light is emitted from the pixel 703(i,j). Alternatively, during a period in which a first selection signal is supplied to the conductive film G1(i), the generated image signal can be supplied to the conductive film S1g(j) and the image signal can be written to the pixel 703(i,j). Alternatively, the generated image signal can be supplied to the conductive film S1g(j) and the conductive film S2g(j) and an enhanced image signal can be written to the pixel 703(i,j). Alternatively, the enhanced image signal can be used to display an image with increased brightness.

[0497] This allows the image FI to be displayed superimposed on the area 231 touched by the subject such as a finger or the nearby first area SH. Alternatively, light can be irradiated onto the area touched by the subject such as a finger using pixel 703(i,j). Alternatively, illumination can be applied to the subject such as a finger THM that is in contact or in close proximity. Alternatively, a user or the like can be prompted to touch or close a subject such as a finger to a previously set area.

[0498] [10th step] In a tenth step, an image of a subject in contact with or close to the first area SH is captured while the image FI is being displayed (see FIG. 22A (V10) and FIG. 22B).

[0499] For example, an image of a finger THM or the like approaching the area 231 is captured while irradiating the finger with light. Specifically, a fingerprint FP of the finger THM in contact with the area 231 can be captured (see FIG. 22C).

[0500] For example, the supply of the first selection signal can be stopped while an image is displayed on pixel 703(i,j). For example, an image can be captured using pixel 703(i,j) while the supply of the first selection signal to pixel circuit 530G(i,j) is stopped.

[0501] This allows an image of a subject such as a finger in contact or in close proximity to be captured while being illuminated. Or, an image can be captured during a period in which the first selection signal is not supplied. Or, noise during imaging can be suppressed. Or, a clear image of a fingerprint can be acquired. Or, an image that can be used for authenticating a user can be acquired. Or, a fingerprint of a finger touching the area 231 can be captured clearly no matter where in the area 231. As a result, a novel information processing device that is excellent in convenience, usefulness, and reliability can be provided.

[0502] [11th step] In the eleventh step, the interrupt process ends (see FIG. 22A (V11)).

[0503] <Configuration example 5 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0504] <<Interrupt Processing>> The interrupt process comprises a sixth step to a ninth step (see FIG. 23A).

[0505] [Sixth step] In the sixth step, if a predetermined event is supplied, the process proceeds to a seventh step, and if the predetermined event is not supplied, the process proceeds to a ninth step (see FIG. 23A (W6)).

[0506] For example, the input unit 240 can be used to supply a predetermined event. Specifically, a touch sensor can be used to use contact or proximity of a finger or the like as the predetermined event. For example, a touch sensor arranged to overlap a location where an image associated with interrupt processing is displayed can be used. Specifically, an image associated with interrupt processing can be displayed in the area 231(1), and the input unit 240 arranged to overlap the area 231(1) can be used.

[0507] [Seventh step] In the seventh step, imaging is performed using area 231(1) (see FIG. 23A(W7)).

[0508] For example, a still image is captured when subject 30 approaches or comes into contact with region 231 (see FIG. 23C). Specifically, a still image is captured when the intensity of external light incident on region 231 becomes smaller than a predetermined value. Alternatively, a still image is captured when no change exceeding a predetermined magnitude is observed in an image captured by region 231 for a predetermined period of time. Alternatively, a still image is captured after the housing of information processing device 200 is closed.

[0509] [8th step] In the eighth step, the area 231(1) is used for display (see FIG. 23A(W8)).

[0510] For example, the still image captured in the seventh step is displayed in the area 231(1) (see FIG. 23D). Specifically, the acquired mirror image is flipped left to right to generate a normal image, which is then displayed.

[0511] [9th step] In the ninth step, the interrupt process ends (see FIG. 23A (W9)).

[0512] This allows an image of a subject, such as a finger, in contact with or in close proximity to the object to be captured while being illuminated. Alternatively, a clear image with reduced distortion can be obtained. Alternatively, information on a printed matter can be copied into electronic data. Alternatively, the device can be used as a flatbed scanner. As a result, a novel information processing device that is highly convenient, useful, and reliable can be provided.

[0513] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

Alternatively, the display unit 5230 has a functional panel, and the functional panel has, for example, a function of displaying on the front, side, top, and back. This makes it possible to display information not only on the front of the mobile phone, but also on the side, top, and back.

[0529] <<Configuration Example 5 of Information Processing Device>> For example, information can be received from the Internet and displayed on the display unit 5230 (see FIG. 25A). A created message can be confirmed on the display unit 5230. A created message can be transmitted to another device. For example, a function is provided for changing the display method according to the illuminance of the usage environment. This makes it possible to reduce the power consumption of the smartphone. For example, an image can be displayed on the smartphone so that it can be used suitably even in an environment with strong external light, such as outdoors on a sunny day.

[0530] Configuration Example 6 of Information Processing Device A remote controller can be used as the input unit 5240 (see FIG. 25B).

Alternatively, the captured image can be transmitted to the Internet. Alternatively, the information processing device includes a function of changing the capture conditions according to the illuminance of the usage environment. This allows the subject to be displayed on the digital camera so that it can be viewed favorably even in an environment with strong external light, such as outdoors on a clear day.

[0534] "Configuration Example 9 of Information Processing Device" For example, the other information processing device can be used as a slave and the information processing device of this embodiment can be used as a master to control the other information processing device (see FIG. 25E). Or, for example, a part of the image information can be displayed on the display unit 5230, and another part of the image information can be displayed on the display unit of the other information processing device. An image signal can be supplied to the other information processing device. Or, information to be written can be obtained from an input unit of the other information processing device using the communication unit 5290.

Alternatively, an image of an augmented reality space can be displayed on a glasses-type information processing device.

[0537] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification.

[0538] 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.

[0539] 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.).

[0540] 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.).

[0541] 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.

[0542] 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.

[0543] 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 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.

[0544] 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.

[0545] 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.

[0546] 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.

[0547] 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.).

[0548] 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]
