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

[0046] In this specification, the state where transistors are connected in series means, for example, a state where only one of the source or drain of the first transistor is connected to only one of the source or drain of the second transistor. Also, the state where transistors are connected in parallel means a state where one of the source or drain of the first transistor is connected to one of the source or drain of the 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.

[0047] 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 state of direct connection, but also includes a state of being indirectly connected through circuit elements such as wiring, resistors, diodes, and transistors so that current, voltage, or potential can be supplied or transmitted.

[0048] In this specification, even when components that are independent on the circuit diagram are connected, in reality, for example, when a part of the wiring functions as an electrode, or when one conductive film has the functions of a plurality of components. In this specification, "connection" includes such cases where one conductive film has the functions of a plurality of components within its scope.

[0068] <Configuration Example 1 of Display Panel.> The display panel 700 described in this embodiment has a display area 231, a functional layer 520A, a functional layer 520B, and a first connection portion 591C(i,y) (see FIGS. 1(A) and 1(B)). (See FIGS. 1(A) and 1(B).)

[0069] 《Configuration Example 1 of Display Area 231.》 The display area 231 includes pixels 702(i,j).

[0070] 《Configuration Example 1 of Pixel 702(i,j).》 The pixel 702(i,j) includes a display element 550(i,j) and a pixel circuit 530(i,j) (see FIGS. 1(B) and 2(B)).

[0071] 《Configuration Example 1 of Functional Layer 520A.》 The functional layer 520A includes the pixel circuit 530(i,j) and the scanning line G1(i) (see FIGS. 2(B) and 4(A)).

[0072] 《Configuration Example 1 of Display Element 550(i,j).》 The display element 550(i,j) is electrically connected to the pixel circuit 530(i,j) (see FIGS. 1(B), 2(B), and 5).

[0073] The display element 550(i,j) has a function of emitting light, and the display element 550(i,j) emits light. ​​​​​​​It includes a layer 553(j) containing a luminescent material (see Fig. 5).

[0074] For example, a display element having a function of emitting light can be used as the display element 550(i,j). Specifically, an organic electroluminescence element, an inorganic electroluminescence element, a light-emitting diode such as a micro LED, or a QDLED (Quantum Do t LED), etc. can be used as the display element 550(i,j).

[0075] 《Configuration Example 1 of the layer 553(j) containing a luminescent material.》 For example, a strip-shaped laminated material that is long in the column direction along the signal line S1(j) and contains a luminescent material can be used for the layer 553(j) containing a luminescent material.

[0076] Specifically, materials that emit light with mutually different hues can be used for the layer 553(j) containing a luminescent material, the layer 553(j + 1 ) and the layer 553(j + 2) containing a luminescent material. Thereby, for example, the hues of the light emitted by the display element 550(i,j) can be made different for each column.

[0077] For example, a material that emits blue light, a material that emits green light, and a material that emits red light can be used as materials that emit light with mutually different hues.

[0078] 《Configuration Example 2 of the layer 553(j) containing a luminescent material.》 For example, a laminated material laminated to emit white light can be used for the layer 553 (j) containing a luminescent material.

[0079] Specifically, materials that emit light with mutually different hues can be used for the layer 553(j) containing a luminescent material. ​

[0080] For example, a layer containing a luminescent material including a fluorescent material that emits blue light, and a layer containing a material other than a fluorescent material that emits green and red light are laminated to form a laminated material that can be used for the layer 553(j) containing the luminescent material. Or a layer containing a luminescent material including a fluorescent material that emits blue light and a layer containing a material other than a fluorescent material that emits yellow light are laminated to form a laminated material that can be used for the layer 553(j) containing the luminescent material.

[0081] For example, a light-emitting unit can be used for the layer 553(j) containing the luminescent material. The light-emitting unit includes a region where electrons injected from one side recombine with holes injected from the other side. Also, the light-emitting unit contains a luminescent material, and the luminescent material emits the energy generated by the recombination of electrons and holes as light.

[0082] For example, a plurality of light-emitting units and an intermediate layer can be used for the layer 553(j) containing the luminescent material. The intermediate layer includes a region sandwiched between two light-emitting units. The intermediate layer has a charge generation region, and the intermediate layer supplies holes to the light-emitting unit arranged on the cathode side and has a function of supplying electrons to the light-emitting unit arranged on the anode side. Also, a configuration including a plurality of light-emitting units and an intermediate layer is sometimes referred to as a tandem-type light-emitting element.

[0083] For example, a light-emitting unit containing a material that emits light of one hue and a light-emitting unit containing a material that emits light of another hue can be used for the layer 553(j) containing the luminescent material.

[0084] For example, a high molecular compound (oligomer, dendrimer, polymer, etc.), a medium molecular compound (low molecular ​​​​​Compounds in the intermediate region between the substrate and the polymer (with a molecular weight of 400 or more and 4000 or less), etc., can be used in the light-emitting material-containing layer 553(j). It can be used in the layer 553(j) containing the light-emitting material.

[0085] 《Electrodes 551(i,j), Electrode 552》 The electrode 551(i,j) is electrically connected to the pixel circuit 530(i,j) at the connection portion 591A (see Fig. 5). It is connected thereto (see Fig. 5).

[0086] For example, materials that can be used for wiring, etc., can be used for the electrode 551(i,j) or the electrode 552. Specifically, materials having translucency for visible light can be used for the electrode 551(i, j) or the electrode 552.

[0087] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide added with gallium, etc., can be used. Or, a metal film that is thin enough for light to pass through can be used. Or Materials having translucency for visible light can be used.

In addition, a metal oxide is used for the semiconductor film of a transistor. In this case, the metal oxide may be interpreted as an oxide semiconductor.

[0194] Oxide semiconductors are classified into single-crystal oxide semiconductors and non-single-crystal oxide semiconductors. As a crystalline oxide semiconductor, CAAC-OS (c-axis-aligned crystal-like oxide semiconductor) talline oxide semiconductor), polycrystalline oxide semiconductor, n c-OS(nanocrystalline oxide semiconductor ) Pseudo-amorphous oxide semiconductors (a-like OS: amorphous-like oxide semiconductor), and amorphous oxide semiconductors, etc. There are also semi-crystalline oxide semiconductors.

[0195] Also, as one of the non-single crystal oxide semiconductors, there is an oxide semiconductor called a semi-crystalline oxide semiconductor. A semi-crystalline oxide semiconductor has an intermediate structure between a single crystal oxide semiconductor and an amorphous oxide semiconductor. A semi-crystalline oxide semiconductor has a more stable structure compared to an amorphous oxide semiconductor. For example, as a semi-crystalline oxide semiconductor, there is an oxide semiconductor having a CAAC structure and a CAC (Cloud-Aligned Composite) configuration. Details of CAC will be described below.

[0196] Also, for the semiconductor film of the transistor disclosed in one aspect of the present invention, CAC-OS (Cloud-Aligned Composite oxide semiconductor) may be used.

[0199] Hereinafter, the details of CAC-OS will be described.

[0200] CAC-OS or CAC-metal oxide has a conductive function in part of the material and an insulating function in part of the material, and has a semiconductor function as a whole. In addition, when CAC-OS or CAC-metal oxide is used in the channel formation region of a transistor, the conductive function is the function of allowing electrons (or holes) serving as carriers to flow, and the insulating function is the function of not allowing electrons serving as carriers to flow. By causing the conductive function and the insulating function to act complementarily, respectively, a switching function (On / Off function) can be imparted to CAC-OS or CAC-metal oxide. In CAC-OS or CAC-metal oxide, by separating the respective functions, both functions can be maximally enhanced. Moreover, CAC-OS or CAC-metal oxide has a conductive region and an insulating region.

In this configuration, when carriers flow, carriers mainly flow in the component having a narrow band gap. Also, the component having a narrow band gap acts complementarily to the component having a wide band gap, and carriers also flow in the component having a wide band gap in conjunction with the component having a narrow band gap. Therefore, when the above CAC-OS or CAC-metal oxide is used in the channel formation region of a transistor, a high current driving force, that is, a large on-current, and a high field-effect mobility can be obtained in the on state of the transistor. In addition, CAC-OS or CAC-metal oxide is composed of components having different band gaps. For example, CAC-OS or CAC-metal oxide is composed of a component having a wide band gap due to an insulating region and a component having a narrow band gap due to a conductive region.

Also, the component having a narrow band gap acts complementarily to the component having a wide band gap, and carriers also flow in the component having a wide band gap in conjunction with the component having a narrow band gap. Therefore, when the above CAC-OS or CAC-metal oxide is used in the channel formation region of a transistor, a high current driving force, that is, a large on-current, and a high field-effect mobility can be obtained in the on state of the transistor. de is composed of a component having a wide band gap due to an insulating region and a component having a narrow band gap due to a conductive region.

[0204] That is, CAC-OS or CAC-metal oxide can also be referred to as a matrix composite or a metal matrix composite. (matrix composite) or a metal matrix composite (metal m atrix composite).

[0205] CAC-OS is, for example, a configuration of a material in which the elements constituting the metal oxide are unevenly distributed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof. In the following, in the metal oxide, one or more metal elements are unevenly distributed, and the region having the metal element is mixed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof, and this state is also referred to as a mosaic state or a patch state. In the following, in the metal oxide, one or more metal elements are unevenly distributed, and the region having the metal element is mixed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof, and this state is also referred to as a mosaic state or a patch state. In the following, in the metal oxide, one or more metal elements are unevenly distributed, and the region having the metal element is mixed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof, and this state is also referred to as a mosaic state or a patch state. In the following, in the metal oxide, one or more metal elements are unevenly distributed, and the region having the metal element is mixed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof, and this state is also referred to as a mosaic state or a patch state. In the following, in the metal oxide, one or more metal elements are unevenly distributed, and the region having the metal element is mixed in a size of 0.5 nm or more and 10 nm or less, preferably 1 nm or more and 2 nm or less or in the vicinity thereof, and this state is also referred to as a mosaic state or a patch state.

[0206] In addition, the metal oxide preferably contains at least indium. In particular, it preferably contains indium and zinc. In addition to these, one or more selected from aluminum, gallium, yttrium, copper, vanadium, beryllium, boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum, lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, or magnesium may be included.

[0207] For example, in the In-Ga-Zn oxide, CAC-OS (among CAC-OS, the In-Ga-Zn oxide may be particularly referred to as CAC-IGZO.) refers to indium oxide (hereinafter, InO (where X1 is a real number greater than 0).), or indium zinc oxide X1 (hereinafter, In Zn X2 Zn Y2 O Z2 (where X2, Y2, and Z2 are real numbers greater than 0).), and gallium oxide (hereinafter, GaO (where X3 is a real number greater than 0). X3 ), or gallium zinc oxide (hereinafter, Ga ) (hereinafter, Ga X4 Zn Y4 O Z4 (where X4, Y4, and Z4 are real numbers greater than 0).) and the like, and the materials are separated to form a mosaic shape, and the mosaic-shaped InO X1 , or In X2 Zn Y2 O Z2 is uniformly distributed in the film (hereinafter, also referred to as cloud-like).

[0208] That is, CAC-OS is GaO X3The region where is the main component and In X2 Zn Y2 O Z2 , or InO X1 The region where is the main component are mixed and have a composite metal oxide structure Note that in this specification, for example, the atomic ratio of In to the element M in the first region is , the atomic ratio of In to the element M in the second region is larger than that in the first region, and the first region is the second Compared with the region of, the concentration of In is assumed to be high.

[0209] Note that IGZO is a general term and refers to one compound of In, Ga, Zn, and O As a representative example, InGaO3(ZnO) m1 (m1 is a natural number), or In (1 +x0) Ga (1-x0) O3(ZnO) m0 (-1≦x0≦1, m0 is an arbitrary number) and the crystalline compounds represented by are mentioned.

[0210] The above crystalline compound has a single crystal structure, a polycrystalline structure, or a CAAC (c-axis al igned crystal) structure. Note that the CAAC structure is a crystal structure in which a plurality of IGZO nanocrystals have c-axis orientation and are connected without orientation in the a-b plane is.

[0211] On the other hand, CAC-OS relates to the material composition of metal oxides. CAC-OS refers to a material composition containing In, Ga , Zn, and O, in which a region observed as nanoparticle-like with Ga as the main component in part and a region observed as nanoparticle-like with In as the main component in part are each mosa It refers to a configuration in which they are randomly dispersed in an ik shape. Therefore, in CAC-OS, the crystal structure Is a secondary element. is.

[0212] Note that CAC-OS does not include a laminated structure of two or more types of films having different compositions. For example, a structure composed of two layers, a film mainly composed of In and a film mainly composed of Ga, is not included.

[0213] Note that GaO X3 in the region where it is the main component and In X2 Zn Y2 O Z2 , or InO X1 in the region where it is the main component may not have a clear boundary.

[0214] Note that when one or more selected from aluminum, yttrium, copper, vanadium, beryllium , boron, silicon, titanium, iron, nickel, germanium, zirconium, molybdenum , lanthanum, cerium, neodymium, hafnium, tantalum, tungsten, or magnesium is included instead of gallium, in some parts of CAC-OS, regions observed as nanoparticles mainly composed of the metal element and, in some parts, regions observed as nanoparticles mainly composed of In are randomly dispersed in a mosaic pattern. This is what is meant by the configuration. That is.

[0215] CAC-OS can be formed by, for example, a sputtering method under conditions where the substrate is not intentionally heated. Also, when CAC-OS is formed by the sputtering method, as the film-forming gas , one or more selected from inert gases (typically argon), oxygen gas, and nitrogen gas may be used. Also, the lower the flow rate ratio of oxygen gas to the total flow rate of the film-forming gas during film formation, the more preferable it is. For example, the flow rate ratio of oxygen gas is preferably 0% or more and less than 30%, preferably 0% or more and 10% or less. That is. That is. That is.

[0216] CAC-OS was measured using an out-of-plane θ / 2θ scan of the X-ray diffraction (XRD) measurement method, which is a specific one, and has the characteristic that no distinct peak is observed. That is, from the analysis result by X-ray diffraction, it can be seen that there is no orientation in the a-b plane direction and the c-axis direction of the measurement region.

[0217] Also, in the electron diffraction pattern obtained by irradiating an electron beam with a probe diameter of 1 nm (also referred to as a nano-beam electron beam), a region with high brightness in a ring shape (ring region) and a plurality of bright spots are observed in the ring region. Therefore, from the electron diffraction pattern, it can be seen that the crystal structure of CAC-OS has an nc ( nano-crystal) structure without orientation in the plane direction and the cross-sectional direction.

[0218] Also, for example, in CAC-OS in In-Ga-Zn oxide, by EDX mapping obtained using energy dispersive X-ray spectroscopy (EDX), it can be confirmed that regions with GaO as the main component and X3 regions with In X2 Zn Y2 O Z2 or InO X1 as the main component are unevenly distributed and mixed to have a structure.

[0219] CAC-OS has a structure different from that of an IGZO compound in which metal elements are uniformly distributed, and has properties different from those of the IG ZO compound. That is, CAC-OS has regions with, for example, GaO X3 as the main component and regions with InX2 Zn Y2 O Z2 、 or InO X1 is a region mainly composed of, and mutually phase-separated, and has a structure in which regions mainly composed of each element are mosaic-shaped.

[0220] Here, In X2 Zn Y2 O Z2 、 or InO X1 The region mainly composed of is a region with higher conductivity compared to the region mainly composed of GaO X3 etc. That is, In X2 Zn Y 2O Z2 、 or InO X1 When the region mainly composed of is the carrier flows, the conductivity as an oxide semiconductor is exhibited. Therefore, In The region mainly composed of is distributed in the oxide semiconductor in a cloud-like shape, thereby realizing a high field-effect X2 Zn Y2 O Z2 、 or InO X 1 as the main component can achieve a high field-effect mobility (μ).

[0221] On the other hand, the region mainly composed of GaO X3 etc. is a region with higher insulation compared to the region mainly composed of In X2 Zn Y2 O Z2 、 or InO X 1 as the main component. That is, GaO X3 etc. When the region mainly composed of is distributed in the oxide semiconductor, the leakage current can be suppressed, and a good switching operation can be realized.

[0222] Therefore, when CAC-OS is used in a semiconductor device, the insulation caused by GaO X3 etc., and In X2 Zn Y2 OZ2 or InO X1 The conductivity caused by the above and the like act complementarily to each other by the following, a high on-current (I on ), and a high field-effect mobility (μ) can be realized .

[0223] In addition, the semiconductor device using CAC-OS has high reliability. Therefore, CAC-OS is optimal for various semiconductor devices including the display panel shown .

A touch sensor having a region overlapping with the display unit 230 can be used. An input / output device including the display unit 230 and a touch sensor having a region overlapping with the display unit 230 can be referred to as a touch panel or a touch screen.

[0286] For example, a user can use a finger touching the touch panel as a pointer to perform various gestures (such as tap, drag, swipe, or pinch-in).

[0287] For example, the arithmetic unit 210 analyzes 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 be assumed that a specific gesture has been supplied. As a result, the user can supply a predetermined operation command associated in advance with a predetermined gesture using the gesture.

[0296] Configuration example 2 of the arithmetic device 210 The arithmetic device 210 includes an artificial intelligence unit 213 (see FIG. 13(A)). , and generates control information CI based on the input information II or the sensed information DS.

Specifically, information specifying a color used for expressing shades (for example, full color, black and white, sepia, or the like) can be used for the control information CI.

[0300] ​​​​​​​​​​​Specifically, the artificial intelligence unit 213 performs image processing on the input information II and extracts some of the images included in the input information II. For example, control information CI for displaying a boundary between a part of the extracted image and another part of the extracted image can be generated.

[0304] [Configuration Example 3 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 FIGS. 14(A) and 14(B).

[0305] [Program] The program according to one aspect of the present invention has the following steps (see FIG. 14(A)).

[0306] [First step] In the first step, initialize the settings (see FIG. 14(A)(S1)).

[0307] 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.

[0308] [Second step] In the second step, permit interrupt processing (see FIG. 14(A)(S2)). Note that the arithmetic unit for which interrupt processing is permitted can perform 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 result obtained by the interrupt processing in the main processing.

[0309] When the value of the counter is the initial value, cause the arithmetic unit 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.

[0310] [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. 14(A)(S3) ). Note that the predetermined mode specifies the mode for displaying information, and the predetermined display method is for the image information ). Specify the display method. Also, for example, it can be used for information to display the image information V1. It is possible.

[0311] For example, one method of displaying the image information V1 can be associated with the first mode. Or, other methods of displaying the image information V1 can be associated with the second mode. Thus, the display method can be selected based on the selected mode.

[0312] 《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.

[0313] For example, when a 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.

[0314] 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.

[0315] 《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.

[0316] 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, display with suppressed flicker or flickering can be achieved. Also, power consumption can be reduced.​​​​

[0317] 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 or the like.

[0318] By the way, for example, when a light-emitting element is used as a display element, the light-emitting element can be caused to emit light in a pulse shape to display image information. Specifically, the organic EL element can be caused to emit light in a pulse shape and the afterglow thereof can be used for display. Since the organic EL element has excellent frequency characteristics , there are cases where the time for driving the light-emitting element can be shortened and the power consumption can be reduced. Also , since heat generation is suppressed, there are cases where deterioration of the light-emitting element can be reduced.

[0319] [Fourth step] In the fourth step, when an end command is supplied, proceed to the fifth step, and when the end command is not supplied, select to proceed to the third step (see Fig. 14(A) (S4) ).

[0320] For example, an end command supplied in interrupt processing may be used for determination.

[0321] [Fifth step] In the fifth step, end (see Fig. 14(A) (S5)).

[0322] 《Interrupt processing》 The interrupt processing includes the following sixth step to eighth step (see Fig. 14(B)) .

[0323] [Sixth step] In the sixth step, for example, using the detection unit 250, detect the illuminance of the environment in which the information processing apparatus 200 is used (see Fig. 14(B) (S6)). Note that instead of the illuminance of the environment, the ambient The color temperature and chromaticity of the ambient light may be detected.

[0324] [Step 7] In the seventh step, a display method is determined based on the detected illuminance information (see Fig. 14(B )(S7). For example, it is determined so that the brightness of the display is not too dark or not too bright.

[0325] If the color temperature and chromaticity of the ambient light are detected in the sixth step, the color tone of the display may be adjusted.

[0326] [Step 8] In the eighth step, the interrupt process is terminated (see Fig. 14(B)(S8)).

[0327] [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. 15.

[0328] Fig. 15(A) is a flowchart for explaining a program according to an aspect of the present invention. Fig. 15 (A) is a flowchart for explaining an interrupt process different from the interrupt process shown in Fig. 14(B).

[0329] Note that Configuration Example 3 of the information processing apparatus has a step of changing the mode based on a supplied predetermined event in the interrupt process, which is different from the interrupt process described with reference to Fig. 14(B). Here, different parts will be described in detail, and the above description will be incorporated for parts where the same configuration can be used.

[0330] [Interrupt Process] The interrupt process includes the following sixth to eighth steps (see Fig. 15(A)). .​​

[0331] [Step 6] In Step 6, if a predetermined event is supplied, proceed to Step 7, if the predetermined event is not supplied, proceed to Step 8 (see Fig. 15(A)(U6 ). For example, it is possible to use as a condition whether or not a predetermined event is supplied within a predetermined period. Specifically, a period of 5 seconds or less, 1 second or less, or preferably 0.1 second or less and longer than 0 seconds can be set as the predetermined period.

[0332] [Step 7] In Step 7, change the mode (see Fig. 15(A)(U7)). Specifically, if the first mode is selected, select the second mode, and if the second mode is selected, select the first mode.

[0333] For example, for a part of the display area of the display unit 230, the display mode can be changed. Specifically, for the area where one driving circuit of the display unit 230 including the driving circuits GDA, GDB, and GDC supplies a selection signal, the display mode can be changed ( see Fig. 15(B)).

[0334] For example, when a predetermined event is supplied to the input unit 240 in the area overlapping the area where the driving circuit GDB supplies a selection signal, the display mode of the area where the driving circuit GDB supplies a selection signal can be changed (see Figs. 15(B) and 15(C)). Specifically, in response to a "tap" event supplied to the touch panel using a finger or the like, the frequency of the selection signal supplied by the driving circuit GDB can be changed.

[0335] ​​​Note that the signal GCLK is a clock signal that controls the operation of the drive circuit GDB, and the signals PWC 1 and PWC2 are pulse width control signals that control the operation of the drive circuit GDB. The drive circuit GDB supplies the selection signal to the scan lines G1(m + 1) to G1(2m) based on the signal GCLK, the signals PWC1 and PWC2, etc.

[0336] Thus, for example, the drive circuit GDB can supply the selection signal without the drive circuits GDA and GDC supplying the selection signal. Or, the display in the area where the drive circuits GDA and GDC supply the selection signal can be changed, and the display in the area where the drive circuit GDB supplies the selection signal can be updated without changing the display in the area where the drive circuits GDA and GDC supply the selection signal. Or, the power consumption of the drive circuit can be suppressed.

[0337] [Step 8] In the eighth step, the interrupt process is terminated (see Fig. 15(A)(U8)). Note that the interrupt process may be repeatedly executed during the period when the main process is being executed.

[0338] 《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 the touch panel using a finger or the like as a pointer can be used.

[0339] Also, for example, the position of the slider indicated by the pointer, the speed of the swipe, the speed of the drag, etc. can be used to give the arguments of the instructions associated with the predetermined event.

[0340] For example, the information detected by the detection unit 250 is compared with a preset threshold value, and the comparison result is can be used for events.

[0341] Specifically, a pressure-sensitive detector that contacts a button or the like that is arranged so that it can be pressed into the housing. etc. can be used for the detection unit 250.

[0342] Commands associated with specific events For example, a termination command may be associated with a particular event.

[0343] For example, a "page turn" function is used to switch the display from one image to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed and other parameters used during execution are sent using a specified event. Can be given.

[0344] For example, the display position of a part of one image information is moved to display a part of the image information that is continuous with the part. You can associate a "scroll command" to display other parts with a specified event. In addition, it determines the speed at which the display moves when executing the "scroll command." Arguments can be provided with a given event.

[0345] For example, a command to set a display method or a command to generate image information is generated by a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a given event. In addition, the argument that determines the brightness of the generated image can be associated with the detection unit 2. The determination may be based on the brightness of the environment detected by 50.

[0346] For example, information distributed using a push-type service, commands to be acquired using the communication unit 290, etc. can be associated with a predetermined event.

[0347] Note that the presence or absence of eligibility to acquire information may be determined using the location information detected by the detection unit 250. Specifically, when in a predetermined classroom, school, conference room, company, building, etc. or within a region, it may be determined that there is eligibility to acquire information. Thereby, for example, teaching materials distributed in a classroom such as a school or university can be received and the information processing apparatus 200 can be used as a textbook, etc. (see Fig. 13(C)). Or, materials distributed in a conference room of a company, etc. can be received and used for meeting materials.

[0348] Note that this embodiment can be appropriately combined with other embodiments shown in this specification.

[0369] Note that this embodiment can be appropriately combined with other embodiments shown in this specification. .

[0370] For example, in this specification and the like, in the case where it is explicitly described that X and Y are connected, it is assumed that the cases where X and Y are electrically connected, where X and Y are functionally connected, and where X and Y are directly connected are disclosed in this specification and the like. . 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 considered to be disclosed in the figure or the text. .

[0371] Here, it is assumed that X and Y are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.). .

[0372] As an example of the case where X and Y are directly connected, an element (for example, a switch, a transistor, a capacitive element, an inductor, a resistive 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. This is the case. An element that enables electrical connection between X and Y (e.g., a switch, transistor, capacitor element, inductor, resistor, diode, display element, light-emitting element, load, etc.) without passing through , where X and Y are connected.

[0373] As an example of the case where X and Y are electrically connected, an element that enables electrical connection between X and Y (e.g., a switch, transistor, capacitor element, inductor, resistor, diode ode, display element, light-emitting element, load, etc.) can be connected with one or more between X and Y.

Note that when X and Y are functionally connected, it shall include the case where X and Y are directly connected and the case where X and Y are electrically connected.

[0375] Note that when it is explicitly described that X and Y are electrically connected, the cases where X and Y are electrically connected (that is, when connected with another element or another circuit interposed between X and Y), the cases where X and Y are functionally connected (that is, when functionally connected with another circuit interposed between X and Y), and the cases where X and Y are directly connected (that is, when connected without another element or another circuit interposed between X and Y) shall be disclosed in this specification and the like. That is, when it is explicitly described that they are electrically connected, the same content as when it is only explicitly described that they are connected

[0376] shall be disclosed in this specification and the like. Note that, for example, when the source (or the first terminal, etc.) of a transistor is electrically connected to X with (or without) passing through Z1, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y with (or without) passing through 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

Using the same expression methods as these examples, by defining the order of connection in the circuit configuration, the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor can be distinguished, and the technical scope can be determined. Or, as another expression method, for example, "The source (or the first terminal, etc.) of the transistor is electrically connected to X via at least the first connection path, and the first connection path does not have a second connection path, and the second connection path is the path through the transistor between the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor." By using the same expression methods as these examples to define the order of connection in the circuit configuration, the source (or the first terminal, etc.) of the transistor and the drain (or the second terminal, etc.) of the transistor can be distinguished, and the technical scope can be determined.

[0380] In addition, the circuit diagram shows independent components as if they are electrically connected to each other. Even if the components are the same, one component may have the functions of multiple components. For example, when a part of the wiring also functions as an electrode, one conductive film has the function of the wiring and The electrode functions as both components. The term "electrochemically connected" refers to a case where one conductive film has the functions of multiple components. This also falls within the scope of the above. [Explanation of symbols]
