[0063] In the drawings attached to this specification, components are classified by function and a block diagram is shown with blocks independent of each other. However, it is difficult to completely separate actual components by function, and one component may be related to multiple functions.

[0064] In this specification, the source and drain of a transistor change their names depending on the polarity of the transistor and the levels of the potentials applied to each terminal. Generally, in an n-channel type transistor, the terminal to which a low potential is applied is called the source, and the terminal to which a high potential is applied is called the drain. Also, in a p-channel type transistor, the terminal to which a low potential is applied is called the drain, and the terminal to which a high potential is applied is called the source. In this specification, for convenience, when explaining the connection relationship of transistors, it is assumed that the source and drain are fixed, but actually the names of the source and drain are interchanged according to the above potential relationship.

[0065] In this specification, the source of a transistor means a source region that is a part of a semiconductor film functioning as an active layer, or a source electrode connected to the semiconductor film.

[0067] In this specification, "connection" means electrical connection, corresponding to a state where current, voltage, or potential can be supplied or transmitted. Therefore, the state of being connected does not necessarily refer to a directly connected state, and a state where they are indirectly connected via circuit elements such as wiring, resistors, diodes, and transistors so that current, voltage, or potential can be supplied or transmitted is also included in this scope.

[0068] Also, in this specification, even if components that are independent on the circuit diagram are connected, actually, for example, when a part of the wiring functions as an electrode, there may be a case where one conductive film has the functions of a plurality of components. In this specification, "connection" includes such a case where one conductive film has the functions of a plurality of components within this scope.

[0069] In addition, in this specification, one of the first electrode or the second electrode of the transistor refers to the source electrode, and the other refers to the drain electrode.

Therefore, the present invention should not be construed as being limited to the description of the embodiments shown below. In the configuration of the invention described below, the same reference numerals are commonly used between different drawings for the same part or parts having the same function, and the repeated description thereof will be omitted.

[0076] (Embodiment 1) In the present embodiment, the functions and configuration of an optical functional device according to an aspect of the present invention will be described with reference to FIGS. 1 and 2.

[0081] <Examples of the light-emitting function> The optical functional device 550RS(i,j) has a light-emitting function of converting electrical energy into light EL1. The light EL1 has an emission spectrum SP11. The emission spectrum SP11 shows a maximum peak at a wavelength λ11, and the maximum peak shows a maximum value Imax. Also, the emission spectrum SP11 has an intensity of 80% of the maximum value Imax at a wavelength λ12. Note that the emission spectrum SP11 is illustrated by normalizing it using the maximum value Imax (see Fig. 1A).

[0082] 《Example 1 of the photoelectric conversion function》 The optical functional device 550RS(i,j) has a photoelectric conversion function, and the photoelectric conversion function has a spectral sensitivity characteristic φ. The spectral sensitivity characteristic φ shows a maximum sensitivity Vmax in the range of 420 nm or more and 720 nm or less at a wavelength λ21. Also, the spectral sensitivity characteristic φ has a sensitivity of 80% of the maximum sensitivity Vmax at a wavelength λ22. Note that the spectral sensitivity characteristic φ is illustrated by normalizing it using the maximum value Vmax (see Fig. 1A). Also, the light incident on the optical functional device 550RS(i,j) is illustrated by light hv1 (see Fig. 1B).

[0083] The wavelength λ21 is located on the λ12 side of the wavelength λ11, and the wavelength λ22 is located on the λ11 side of the wavelength λ21. Note that the case where the wavelength λ21 is on the shorter wavelength side than the wavelength λ11 is illustrated, but it is not limited to this. For example, the wavelength λ21 may be on the longer wavelength side than the wavelength λ11. Specifically, the wavelength λ11 may be located in the wavelength region of green light, and the wavelength λ21 may be located in the wavelength region of red light or the wavelength region of near-infrared light.

[0084] 《Example 1 of the structure of the optical functional layer 553RS(j)》 The optical functional layer 553RS(j) has a region sandwiched between the electrode 551RS(i,j) and the electrode 552, and the optical functional layer 553RS(j) includes a layer 553R(j) and a layer 553S(j) (see Fig. 1B).

[0085] Layer 553R(j) emits light including light EL1. For example, a light-emitting organic material can be used for layer 553R(j). Specifically, a fluorescent material or a phosphorescent material can be used for layer 553R(j). Alternatively, the light-emitting organic material can be dispersed and used in a material having carrier transport properties.

Preferably, in this range, a range of 50% or more of the area of the normalized absorption spectrum ABS overlaps with the normalized spectral sensitivity characteristic φ. More preferably, in this range, a range of 65% or more of the area of the normalized absorption spectrum ABS overlaps with the normalized spectral sensitivity characteristic φ.

[0087] For example, known materials that can be used for an organic solar cell can be used for layer 553S(j). Specifically, an electron-accepting material and an electron-donating material can be used for layer 553S(j). For example, a fullerene derivative, a non-fullerene electron acceptor, etc. can be used for the electron-accepting material. Specifically, a perylene derivative or a compound having a dicyanomethylene indanone group, etc. can be used for the non-fullerene electron acceptor. Also, a phthalocyanine compound, a tetracene derivative, a quinacridone derivative, a rubrene derivative, etc. can be used for the electron-donating material.

[0088] <<Example 2 of the photoelectric conversion function>> The optical functional device 550RS(i,j) described in this embodiment has a wavelength λ21 that is shorter than the wavelength λ11.

Or, the absorption of the light EL by the light-absorbing material can be suppressed. Or, the light EL1 can be efficiently emitted. Or, photoelectric conversion can be performed with the spectral sensitivity characteristic φ. As a result, a novel optical functional device excellent in convenience, usefulness, or reliability can be provided.

[0090] <Configuration Example 2 of the Optical Functional Device> The optical functional device 550RS(i,j) described in this embodiment has a light-emitting function, a photoelectric conversion function, an electrode 551RS(i,j), an electrode 552, and an optical functional layer 553RS(j) (see FIGS. 1A and 1B).

[0091] <Example of the Light-Emitting Function> The optical functional device 550RS(i,j) has a light-emitting function of converting electrical energy into the light EL1. The light EL1 has an emission spectrum SP11. The emission spectrum SP11 shows a maximum peak at the wavelength λ11.

[0092] <Example 3 of the Photoelectric Conversion Function> The optical functional device 550RS(i,j) has a photoelectric conversion function, and the photoelectric conversion function has a spectral sensitivity characteristic φ. The spectral sensitivity characteristic φ shows a maximum sensitivity Vmax in the range of 420 nm or more and 720 nm or less at the wavelength λ21.

[0093] The wavelength λ21 is located in a wavelength range of 420 nm or more and less than the wavelength λ11.

[0094] <Configuration Example 2 of the Optical Functional Layer 553RS(j)> The optical functional layer 553RS(j) includes a region sandwiched between the electrode 551RS(i,j) and the electrode 552, and the optical functional layer 553RS(j) includes a layer 553R(j) and a layer 553S(j) (see FIG. 1B).

[0095] Layer 553R(j) emits light including light EL1.

[0096] Layer 553S(j) contains a light-absorbing material. The light-absorbing material has an absorption spectrum ABS, and the absorption spectrum ABS has a region overlapping with the spectral sensitivity characteristic φ. Specifically, the absorption spectrum ABS normalized using the maximum absorption in the range of 420 nm or more and 720 nm or less overlaps with the spectral sensitivity characteristic φ normalized using the maximum value Vmax in the range of 420 nm or more and 720 nm or less. Preferably, in this range, a range of 50% or more of the area of the normalized absorption spectrum ABS overlaps with the normalized spectral sensitivity characteristic φ. More preferably, in this range, a range of 65% or more of the area of the normalized absorption spectrum ABS overlaps with the normalized spectral sensitivity characteristic φ.

[0097] As a result, it is possible to obtain the spectral sensitivity characteristic φ that shows high sensitivity to light having a wavelength shorter than the maximum peak of the emission spectrum SP11.

[0197] For example, a transistor with a leakage current in the off state smaller than that of a transistor using amorphous silicon for the semiconductor film can be used. Specifically, a transistor using an oxide semiconductor for the semiconductor film can be used for a switch or the like. Thereby, the potential of the floating node can be held for a longer time compared to a circuit using a transistor with amorphous silicon for the switch.

[0198] For example, a 25-nm-thick film containing indium, gallium, and zinc can be used for the semiconductor film 508.

[0199] For example, a conductive film formed by laminating a 10-nm-thick film containing tantalum and nitrogen and a 300-nm-thick film containing copper can be used for the conductive film 504. Note that the copper-containing film has a region sandwiching the tantalum- and nitrogen-containing film between it and the insulating film 506.

[0200] For example, a laminated film formed by laminating a 400-nm-thick film containing silicon and nitrogen and a 200-nm-thick film containing silicon, oxygen, and nitrogen can be used for the insulating film 506.

Note that the tungsten-containing film has a region in contact with the semiconductor film 508.

[0202] By the way, for example, a manufacturing line for a bottom-gate type transistor using amorphous silicon as a semiconductor can be easily modified into a manufacturing line for a bottom-gate type transistor using an oxide semiconductor as a semiconductor. Also, for example, a manufacturing line for a top-gate type transistor using polysilicon as a semiconductor can be easily modified into a manufacturing line for a top-gate type transistor using an oxide semiconductor as a semiconductor. Any of these modifications can effectively utilize an existing manufacturing line.

[0305] <Configuration Example 3 of Functional Panel 700> Also, the functional panel 700 according to one aspect of the present invention has a drive circuit GD, a drive circuit RD, and a set of pixels 703(i,j). The drive circuit GD has a function of supplying a first selection signal, and the drive circuit RD has a function of supplying a third selection signal and a fourth selection signal.

[0306] 《Configuration Example 1 of Pixel 703(i,j)》 A set of pixels 703(i,j) is supplied with a third selection signal and a fourth selection signal during a period when the first selection signal is not supplied (see FIG. 13). The pixel circuit 530RS(i,j) acquires an imaging signal based on the third selection signal and supplies the imaging signal based on the fourth selection signal.

[0307] Note that, for example, the first selection signal can be supplied using the conductive film G1(i), the third selection signal can be supplied using the conductive film TX(i), and the fourth selection signal can be supplied using the conductive film SE(i) (see FIG. 5).

[0308] Also, the operation of supplying the third selection signal and causing the pixel circuit 530RS(i,j) to acquire the imaging signal can be referred to as "imaging" (see FIG. 13). Also, the operation of reading out the imaging signal from the pixel circuit 530RS(i,j) can be referred to as "reading out". Also, the operation of supplying a predetermined voltage to the optical function device 550RS(i,j) can be referred to as "initialization", the operation of exposing the optical function device 550RS(i,j) to light for a predetermined period after initialization can be referred to as "exposure", and the operation of reflecting the voltage changed due to exposure to the pixel circuit 530RS(i,j) can be referred to as "transfer". Also, in the figure, 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 the imaging signal.

[0309] For example, the image information of one frame can be written in 16.7 ms. Specifically, it can operate at a frame rate of 60 Hz. Note that the image signal can be written to the pixel circuit 530G(i,j) in 15.2 μs.

[0310] For example, the image information of one frame can be held for a period corresponding to 16 frames. Alternatively, the imaging information of one frame can be captured and read out in a period corresponding to 16 frames.

[0311] Specifically, it can be initialized in 15 μs, exposed for 1 ms or more and 5 ms or less, and transferred in 150 μs. Alternatively, it can be read out in 250 ms.

[0312] Thus, imaging can be performed during a period when the first selection signal is not supplied. Or, noise during imaging can be suppressed. Or, during a period when the first selection signal is not supplied, an imaging signal can be read. Or, noise during reading can be suppressed. As a result, a novel functional panel excellent in convenience, utility, or reliability can be provided.

[0313] 《Configuration Example 2 of Pixel 703(i,j)》 Pixel 703(i,j) is supplied with a third selection signal during a period when it holds one image signal. For example, during a period when pixel circuit 530G(i,j) holds one image signal, pixel 703(i,j) can emit light based on the image signal using light-emitting device 550G(i,j) (see FIG. 13). Or, after pixel circuit 530G(i,j) acquires one image signal based on the first selection signal, until the first selection signal is supplied again, pixel circuit 530RS(i,j) is supplied with the third selection signal.

[0314] Thus, the intensity of the light emitted by light-emitting device 550G(i,j) can be controlled using the image signal. Or, the subject can be irradiated with light whose intensity is controlled. Or, the subject can be imaged using optical function device 550RS(i,j). Or, the subject can be imaged using optical function device 550RS(i,j) while controlling the intensity of the irradiated light. Or, the influence on the imaging signal caused by the change of the signal held by pixel circuit 530G(i,j) from one image signal to another image signal can be eliminated. As a result, a novel functional panel excellent in convenience, utility, or reliability can be provided.

[0338] Note that this embodiment can be appropriately combined with other embodiments shown in this specification.

[0339] (Embodiment 6) In this embodiment, the configuration of the input / output device according to one aspect of the present invention will be described with reference to the drawings.

[0340] FIG. 15 is a block diagram for explaining the configuration of the input / output device according to one aspect of the present invention.

[0341] <Configuration Example 1 of Input / Output Device> The input / output device described in this embodiment includes an input unit 240 and a display unit 230 (see FIG. 15).

[0342] <<Configuration Example 1 of Display Unit 230>> The display unit 230 includes a function panel 700.

Alternatively, position information can be input using a finger or the like approaching the display unit 230 as a pointer. Alternatively, the position information can be associated with the image information displayed on the display unit 230. As a result, a novel input / output device excellent in convenience, usefulness, or reliability can be provided.

[0346] <<Configuration Example 1 of Detection Area 241>> The detection area 241 includes, for example, one or more detectors.

[0347] The detection area 241 has a group of detectors 802(g, 1) to detectors 802(g, q) and another group of detectors 802(1, h) to detectors 802(p, h). Note that g is an integer from 1 to p, h is an integer from 1 to q, and p and q are integers of 1 or more.

[0348] A group of detectors 802(g,1) to 802(g,q) includes the detector 802(g,h), is arranged in the row direction (the direction indicated by the arrow R2 in the figure), and is electrically connected to the conductive film CL(g).

Alternatively, a signal for changing the display of a part of the image information VI can be used for the control information CI.

[0379] The input / output device 220 includes a display unit 230, an input unit 240, and a detection unit 250. For example, the input / output device described in Embodiment 4 can be used for the input / output device 220. Further, the input / output device 220 can include a communication unit 290.

[0380] 《Configuration example of the 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 Embodiment 3 can be used for the display unit 230.

[0381] 《Configuration example of the 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.

[0382] For example, a human interface or the like can be used for the input unit 240 (see FIG. 16A). Specifically, a keyboard, a mouse, a touch sensor, a microphone, a camera, or the like can be used for the input unit 240.

[0383] Further, a touch sensor having an area overlapping with the display unit 230 can be used. 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 referred to as a touch panel or a touch screen.

[0384] For example, the user can use the finger touching the touch panel as a pointer to perform various gestures (such as tap, drag, swipe, or pinch-in).

[0385] For example, the arithmetic unit 210 can analyze information such as the position or trajectory of a finger touching the touch panel, and assume that a predetermined gesture is supplied when the analysis result satisfies a predetermined condition. Thereby, the user can supply a predetermined operation command associated in advance with the predetermined gesture by using the gesture.

[0395] Configuration Example 2 of the Calculation Device 210 The computing device 210 includes an artificial intelligence unit 213 (see FIG. 16A).

[0396] 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.

[0404] Note that a clock signal or a timing signal supplied to the control unit 238 provided in the display unit 230, etc., can be used in the control information CI. Alternatively, a clock signal or a timing signal supplied to the control unit provided in the input unit 240, etc., can be used in the control information CI.

[0405] [Configuration Example 2 of Information Processing Apparatus] Another configuration of the information processing apparatus according to one aspect of the present invention will be described with reference to FIGS. 17A and 17B.

[0406] 《Program》 The program according to one aspect of the present invention has the following steps (see FIG. 17A).

[0407] [First step] In the first step, initialize the settings (see FIG. 17A (S1)).

[0408] For example, acquire from the storage unit 212 predetermined image information to be displayed at startup, a predetermined mode for displaying the image information, and information specifying a predetermined display method for displaying the image information. 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.

[0409] [Second step] In the second step, permit interrupt processing (see FIG. 17A (S2)). Note that an arithmetic unit permitted interrupt processing can perform interrupt processing in parallel with the main processing. The arithmetic unit that has returned from interrupt processing to the main processing can reflect the result obtained by the interrupt processing in the main processing.

[0410] When the value of the counter is the initial value, the arithmetic unit may be made to perform interrupt processing, and when returning from the interrupt processing, the counter may be set to a value other than the initial value. Thereby, interrupt processing can always be performed after the program is started.

[0411] [Third step] In the third step, display the image information using the predetermined mode or the predetermined display method selected in the first step or the interrupt processing (see FIG. 17A (S3)). Note that the predetermined mode specifies the mode for displaying information, and the predetermined display method specifies the method for displaying the image information. Also, for example, it can be used for information for displaying the image information VI.

[0412] For example, one method of displaying the image information VI can be associated with a first mode. Alternatively, another method of displaying the image information VI can be associated with a second mode. Thereby, the display method can be selected based on the selected mode.

[0413] 《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.

[0414] For example, when the selection signal is supplied at a frequency of 30 Hz or more, preferably 60 Hz or more, the movement of the moving image can be smoothly displayed.

[0415] For example, when the image is updated at a frequency of 30 Hz or more, preferably 60 Hz or more, an image that smoothly follows the user's operation can be displayed on the information processing apparatus 200 during the user's operation.

[0416] 《Second Mode》 Specifically, a method of supplying a selection signal to one scanning line at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than once per minute, and performing display based on the selection signal can be associated with the second mode.

[0417] When the selection signal is supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than once per minute, a display with suppressed flicker or flickering can be performed. Also, power consumption can be reduced.

[0418] For example, when the information processing apparatus 200 is used as a clock, the display can be updated at a frequency of once per second or once per minute.

[0419] Incidentally, for example, when a light-emitting device is used as a display element, the light-emitting device can be caused to emit light in a pulsed manner to display image information. Specifically, an organic EL element can be caused to emit light in a pulsed manner, and the afterglow thereof 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 device and reduce power consumption. Alternatively, since heat generation is suppressed, it may be possible to reduce the degradation of the light-emitting device. Also, when the duty ratio is set to 20% or less, afterimages included in the display can be reduced.

[0420] [Fourth step] In the fourth step, if an end command is supplied (Yes), proceed to the fifth step, and if no end command is supplied (No), select to proceed to the third step (see Fig. 17A (S4)).

[0421] For example, the end command supplied in the interrupt process may be used for the determination.

[0422] [Fifth step] In the fifth step, end (see Fig. 17A (S5)).

[0423] 《Interrupt process》 The interrupt process includes the following sixth to eighth steps (see Fig. 17B).

[0424] [Sixth step] In the sixth step, for example, using the detection unit 250, the illuminance of the environment in which the information processing apparatus 200 is used is detected (see Fig. 17B (S6)). Note that instead of the illuminance of the environment, the color temperature or chromaticity of the ambient light may be detected.

[0425] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (see Fig. 17B (S7)). For example, it is determined so that the display is not too dark or not too bright.

[0426] In addition, when detecting the color temperature of the ambient light and the chromaticity of the ambient light in the sixth step, the color tone of the display may be adjusted.

[0427] [Eighth step] In the eighth step, end the interrupt process (see FIG. 17B (S8)).

[0428] [Configuration example 3 of the information processing apparatus] Another configuration of the information processing apparatus according to an aspect of the present invention will be described with reference to FIG. 18.

[0429] FIG. 18A is a flowchart for explaining a program according to an aspect of the present invention. FIG. 18A is a flowchart for explaining an interrupt process different from the interrupt process shown in FIG. 17B.

[0430] Note that the configuration example 3 of the information processing apparatus is different from the interrupt process described with reference to FIG. 17B in that the interrupt process has a step of changing the mode based on a supplied predetermined event. Here, different parts will be described in detail, and the above description will be incorporated for parts where the same configuration can be used.

[0431] [Interrupt process] The interrupt process includes the following sixth step to eighth step (see FIG. 18A).

[0432] [Sixth step] In the sixth step, when a predetermined event is supplied (Yes), proceed to the seventh step, and when a predetermined event is not supplied (No), proceed to the eighth step (see FIG. 18A (U6)). For example, it is possible to use as a condition whether a predetermined event is supplied within a predetermined period. Specifically, a period of 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less and longer than 0 seconds can be used as the predetermined period.

[0433] [Seventh step] In the seventh step, change the mode (see FIG. 18A (U7)). Specifically, if the first mode is selected, select the second mode, and if the second mode is selected, select the first mode.

[0434] For example, for a part of the area of the display unit 230, the display mode can be changed. Specifically, for the area to which one drive circuit of the display unit 230 including the drive circuit GDA, the drive circuit GDB, and the drive circuit GDC supplies a selection signal, the display mode can be changed (see FIG. 18B).

[0435] For example, when a predetermined event is supplied to the input unit 240 in an area overlapping with the 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. 18B and 18C). Specifically, the frequency of the selection signal supplied by the drive circuit GDB can be changed according to a "tap" event supplied to the touch panel using a finger or the like.

[0436] Note that the signal GCLK is a clock signal for controlling the operation of the drive circuit GDB, and the signals PWC1 and PWC2 are pulse width control signals for controlling the operation of the drive circuit GDB. The drive circuit GDB supplies a selection signal to the conductive films G2(m + 1) to G2(2m) based on the signal GCLK, the signal PWC1, the signal PWC2, etc.

[0437] Thereby, for example, the drive circuit GDB can supply a selection signal without the drive circuits GDA and GDC supplying a selection signal. Or, the display of the area to which the drive circuit GDB supplies a selection signal can be updated without changing the display of the areas to which the drive circuits GDA and GDC supply selection signals. Or, the power consumption of the drive circuit can be suppressed.

[0438] [Eighth step] In the eighth step, end the interrupt process (see Fig. 18A (U8)). Note that the interrupt process may be repeatedly executed during the period when the main process is being executed.

[0439] 《Predetermined event》 For example, events such as "click" and "drag" supplied using a pointing device such as a mouse, or events such as "tap", "drag", or "swipe" supplied to a touch panel using a finger or the like as a pointer can be used.

[0440] Also, for example, arguments of commands associated with a predetermined event can be given using the position of a slide bar indicated by the pointer, the speed of a swipe, the speed of a drag, or the like.

[0441] 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 an event.

[0442] Specifically, a pressure sensor or the like that contacts a button or the like arranged so as to be pushed into the housing can be used as the detection unit 250.

[0443] 《Commands associated with a predetermined event》 For example, an end command can be associated with a predetermined event.

[0444] For example, a "page turning command" for switching the display from one piece of image information being displayed to another piece of image information can be associated with a predetermined event. Note that an argument for determining the speed of turning the page used when executing the "page turning command" can be given using a predetermined event.

[0445] For example, a "scroll command" that moves the display position of a part of an image information being displayed and displays other parts continuous with the part can be associated with a predetermined event. Note that an argument for determining the speed of moving the display used when executing the "scroll command" can be given using a predetermined event.

[0446] For example, a command for setting a display method or a command for generating image information can be associated with a predetermined event. Note that an argument for determining the brightness of the generated image can be associated with a predetermined event. Further, the argument for determining the brightness of the generated image may be determined based on the brightness of the environment detected by the detection unit 250.

[0447] For example, a command for acquiring information distributed using a push-type service using the communication unit 290 can be associated with a predetermined event.

[0448] Note that the presence or absence of the qualification to acquire information may be determined using the position information detected by the detection unit 250. Specifically, when being inside or in a region of a predetermined classroom, school, conference room, company, building, etc., it may be determined that there is a qualification to acquire information. Thereby, for example, teaching materials distributed in a classroom of a school or a university can be received and the information processing apparatus 200 can be used as a textbook or the like (see FIG. 16C). Or, materials distributed in a conference room of a company or the like can be received and used as conference materials.

[0449] <Configuration Example 4 of Information Processing Apparatus> Another configuration of the information processing apparatus according to an aspect of the present invention will be described with reference to FIG. 19.

[0450] Note that Configuration Example 4 of the information processing apparatus described with reference to FIG. 19A has different interrupt processing from Configuration Example described with reference to FIG. 17B. Specifically, based on a supplied predetermined event, the steps of identifying a region, generating an image, displaying the image, and imaging are performed by the interrupt processing. Here, different parts will be described in detail, and the above description will be incorporated for parts where the same configuration can be used.

[0451] 《Interrupt Processing》 The interrupt processing includes the sixth to eleventh steps (see FIG. 19A).

[0452] [Sixth Step] In the sixth step, if a predetermined event is supplied (Yes), the process proceeds to the seventh step, and if a predetermined event is not supplied (No), the process proceeds to the eleventh step (see FIG. 19A (V6)).

[0453] For example, the detection unit 250 can be used to supply a predetermined event. Specifically, a movement such as lifting the information processing apparatus can be used as the predetermined event. For example, an angular acceleration sensor or an acceleration sensor can be used to detect the movement of the information processing apparatus. Alternatively, a touch sensor can be used to detect contact of a finger or the like or the proximity of a subject.

[0454] [Seventh Step] In the seventh step, the first region SH is identified (see FIG. 19A (V7)).

[0455] For example, for the input / output device 220 according to an aspect of the present invention, a region where a subject such as a finger is in contact or proximity can be set as the first region SH. Alternatively, a region preset by the user or the like can be used as the first region SH.

[0456] Specifically, a finger THM or the like that contacts or is close to the function panel according to one aspect of the present invention can be photographed using the pixel 703(i,j), and image processing can be performed to identify the first region SH (see FIG. 19B).

[0457] For example, due to the contact or proximity of a subject such as a finger THM, the shadow generated by the blocking of external light can be photographed using the pixel 703(i,j) of the function panel according to one aspect of the present invention, and image processing can be performed to identify the first region SH.

[0458] Alternatively, using the pixel 703(i,j) of the function panel according to one aspect of the present invention, light can be irradiated onto a subject such as a finger THM that contacts or is close, the light reflected by the subject can be photographed using the pixel 703(i,j), and image processing can be performed to identify the first region SH.

[0459] Alternatively, using a touch sensor, the region touched by a subject such as a finger THM can be identified as the first region SH.

[0460] [Step 8] In the eighth step, an image FI including the second region and the third region is generated based on the first region SH (see FIGS. 19A(V8) and 19B). 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.

[0461] [Step 9] In the ninth step, the image FI is displayed so that the second region overlaps the first region SH (see FIGS. 19A(V9) and 19B).

[0462] For example, an image signal is generated from the image FI, supplied to the region 231, and light is emitted from the pixel 703(i,j). Alternatively, during the period when the first selection signal is supplied to the conductive film G1(i), the generated image signal is supplied to the conductive film S1g(j), and the image signal can be written into the pixel 703(i,j). Alternatively, the generated image signal is supplied to the conductive film S1g(j) and the conductive film S2g(j), and the emphasized image signal can be written into the pixel 703(i,j). Alternatively, the luminance can be increased and displayed using the emphasized image signal.

[0463] Thereby, the image FI can be displayed superimposed on the region 231 touched by a subject such as a finger or the adjacent first region SH. Alternatively, the pixel 703(i,j) can be used to irradiate light on the region touched by a subject such as a finger. Alternatively, illumination can be applied to a subject such as a finger THM in contact or proximity. Alternatively, a user or the like can be prompted to contact or approach a subject such as a finger to a preset region.

[0464] [Step 10] In the tenth step, while the image FI is being displayed, a subject in contact or proximity to the first region SH is imaged (see FIGS. 19A(V10) and 19B).

[0465] For example, while irradiating light on a finger THM or the like in proximity to the region 231, the finger or the like is photographed. Specifically, the fingerprint FP of the finger THM in contact with the region 231 can be photographed (see FIG. 19C).

[0466] For example, the supply of the first selection signal can be stopped while an image is being displayed on the pixel 703(i,j). For example, imaging can be performed using the pixel 703(i,j) while the supply of the first selection signal to the pixel circuit 530G(i,j) is stopped.

[0467] As a result, it is possible to image a subject such as a finger in contact with or in proximity to while illuminating it. Or, it is possible to image during a period when the first selection signal is not supplied. Or, it is possible to suppress noise during imaging. Or, it is possible to obtain a clear image of a fingerprint. Or, it is possible to obtain an image that can be used for user authentication. Or, regardless of where in the region 231, it is possible to clearly photograph the fingerprint of a finger touching the region 231. As a result, it is possible to provide a novel information processing apparatus excellent in convenience, usefulness, or reliability.

[0468] [Step 11] In the 11th step, end the interrupt process (see Fig. 19A (V11)).

[0469] <Configuration Example 5 of Information Processing Apparatus> Another configuration of the information processing apparatus according to an aspect of the present invention will be described with reference to Fig. 20.

[0470] <<Interrupt Process>> The interrupt process includes the 6th step to the 9th step (see Fig. 20A).

[0471] [Step 6] In the 6th step, if a predetermined event is supplied (Yes), proceed to the 7th step, and if a predetermined event is not supplied (No), proceed to the 9th step (see Fig. 20A (W6)).

[0472] For example, a subject 30 can be placed at a predetermined position of the information processing apparatus 200, and a predetermined event can be supplied using the input unit 240 (see Fig. 20B). Specifically, contact or proximity such as a finger can be detected using the touch sensor in the region 231(1) and used as a predetermined event. For example, a touch sensor arranged overlapping the place where an image associated with the interrupt process is displayed can be used. Specifically, an image associated with the interrupt process can be displayed in the region 231(1), and the input unit 240 arranged overlapping the region 231(1) can be used.

[0473] [Step 7] In Step 7, imaging is performed using the area 231(1) (see FIG. 20A (W7)).

[0474] For example, when the subject 30 is close to or in contact with the area 231, a still image is captured (see FIG. 20C). Specifically, when the intensity of external light incident on the area 231 becomes smaller than a predetermined value, a still image is captured. Alternatively, when there is no change exceeding a predetermined size in the image captured by the area 231 for a predetermined period, a still image is captured. Alternatively, a still image is captured after the housing of the information processing apparatus 200 is closed.

[0475] [Step 8] In Step 8, display is performed using the area 231(1) (see FIG. 20A (W8)).

[0476] For example, the still image captured in Step 7 is displayed on the area 231 (see FIG. 20D).

[0477] [Step 9] In Step 9, the interrupt process is terminated (see FIG. 20A (W9)).

[0478] As a result, it is possible to image a subject such as a finger in contact with or close to while illuminating it. Alternatively, it is possible to obtain a clear image with suppressed distortion. Alternatively, it is possible to copy information published in a printed matter or the like into electronic data. As a result, it is possible to provide a novel information processing apparatus excellent in convenience, usefulness, or reliability.

[0505] Note that this embodiment can be appropriately combined with other embodiments described in this specification.

[0506] For example, in this specification and the like, when it is explicitly described that X and Y are connected, it is disclosed in this specification and the like that X and Y are electrically connected, X and Y are functionally connected, and X and Y are directly connected. Therefore, it is not limited to a predetermined connection relationship, for example, the connection relationship shown in the figure or the text, and those other than the connection relationship shown in the figure or the text are also disclosed in the figure or the text.

[0507] Here, it is assumed that X and Y are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).

[0508] As an example of the case where X and Y are directly connected, it is a case where an element (for example, a switch, a transistor, a capacitor element, an inductor, a resistor element, a diode, a display element, a light-emitting element, a load, etc.) that enables electrical connection between X and Y is not connected between X and Y, and X and Y are connected without passing through an element (for example, a switch, a transistor, a capacitor element, an inductor, a resistor element, a diode, a display element, a light-emitting element, a load, etc.) that enables electrical connection between X and Y.

[0509] As an example of the case where X and Y are electrically connected, one or more elements that enable electrical connection between X and Y (for example, a switch, transistor, capacitor, inductor, resistor, diode, display element, light-emitting element, load, etc.) can be connected between X and Y. Note that the switch has a function of controlling on / off. That is, the switch can be in a conductive state (on state) or a non-conductive state (off state), and has a function of controlling whether or not to allow current to flow. Or, the switch has a function of selecting and switching the path through which current flows. Note that when X and Y are electrically connected, it includes the case where X and Y are directly connected.

[0510] As an example of the case where X and Y are functionally connected, one or more circuits that enable functional connection between X and Y (for example, a logic circuit (such as an inverter, NAND circuit, NOR circuit, etc.), a signal conversion circuit (such as a DA conversion circuit, AD conversion circuit, gamma correction circuit, etc.), a potential level conversion circuit (such as a power supply circuit (step-up circuit, step-down circuit, etc.), a level shifter circuit that changes the potential level of a signal, etc.), a voltage source, a current source, a switching circuit, an amplification circuit (a circuit that can increase a signal amplitude or current amount, such as an operational amplifier, differential amplification circuit, source follower circuit, buffer circuit, etc.), a signal generation circuit, a memory circuit, a control circuit, etc.) can be connected between X and Y. Note that as an example, even if another circuit is interposed between X and Y, when the signal output from X is transmitted to Y, X and Y are considered to be functionally connected. Note that when X and Y are functionally connected, it includes the case where X and Y are directly connected and the case where X and Y are electrically connected.

[0511] In addition, when it is explicitly described that X and Y are electrically connected, the cases where X and Y are electrically connected (i.e., connected with another element or another circuit interposed therebetween), the cases where X and Y are functionally connected (i.e., functionally connected with another circuit interposed therebetween), and the cases where X and Y are directly connected (i.e., connected without another element or another circuit interposed therebetween) shall be those disclosed in this specification and the like. That is, when it is explicitly described that X and Y are electrically connected, the same content as when it is only explicitly described that they are connected shall be those disclosed in this specification and the like.

[0512] In addition, for example, when the source (or the first terminal, etc.) of a 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.

[0513] For example, it can be expressed as "X, the source (or the first terminal, etc.) of the transistor, and the drain (or the second terminal, etc.) of the transistor are electrically connected to each other, and they are electrically connected in the order of X, the source (or the first terminal, etc.) of the transistor, the drain (or the second terminal, etc.) of the transistor, and Y." Or, it can be expressed as "The source (or the first terminal, etc.) of the transistor is electrically connected to X, the drain (or the second terminal, etc.) of the transistor is electrically connected to Y, and X, the source (or the first terminal, etc.) of the transistor, the drain (or the 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 via the source (or the first terminal, etc.) and the drain (or the second terminal, etc.) of the transistor, and X, the source (or the first terminal, etc.) of the transistor, the drain (or the second terminal, etc.) of the transistor, and Y are provided in this connection order." By stipulating the connection order in the circuit configuration using an expression method similar to these examples, the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor can be distinguished to determine the technical scope.

[0514] Alternatively, as another way of expression, 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 the first connection path, the first connection path does not have the 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 the transistor, the first connection path is a path via Z1, the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via at least the third connection path, the third connection path does not have the second connection path, and the third connection path is a path via Z2." Or, 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 the first connection path, the first connection path does not have the second connection path, the second connection path has a connection path via the transistor, the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least the third connection path, and the third connection path does not have the second connection path." Or, 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 the first electrical path, the first electrical path does not have the second electrical path, the second electrical path is an electrical path from the source (or the first terminal, etc.) of the transistor to the drain (or the second terminal, etc.) of the transistor, the drain (or the second terminal, etc.) of the transistor is electrically connected to Y via Z2 by at least the third electrical path, the third electrical path does not have the fourth electrical path, and the fourth electrical path is an electrical path from the drain (or the second terminal, etc.) of the transistor to the source (or the first terminal, etc.) of the transistor." By defining the connection paths in the circuit configuration using an expression method similar to these examples, the source (or the first terminal, etc.) and the drain (or the second terminal, etc.) of the transistor can be distinguished to determine the technical scope.

[0515] Note that these expression methods are just examples and are not limited to these expression methods. Here, X, Y, Z1, and Z2 are assumed to be objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).

[0516] Note that even if components that are independent on the circuit diagram are shown as being electrically connected, one component may have the functions of multiple components combined. For example, when a part of the wiring also functions as an electrode, one conductive film has the functions of both the wiring component and the electrode component combined. Therefore, the electrically connected in this specification includes such cases where one conductive film has the functions of multiple components combined within its scope.
