Generally, n-channel In a 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 source. The terminal that is exposed to low potential is called the drain. Also, in p-channel transistors, when a low potential is applied... The terminal to which the current is applied is called the drain, and the terminal to which a high potential is applied is called the source. So, for convenience, let's assume that the source and drain are fixed, and the transistor's connections Although the relationship is sometimes explained, in reality, the source and drain are called according to the potential relationship described above.

It can be used in the layer 553(j). Also, for example, the color conversion layer can be made of a light-emitting material. It can be used in conjunction with the containing layer 553(j).

[0215] For example, a material that emits light with a wavelength longer than the wavelength of incident light is called a color conversion layer CC(j). It can be used for purposes such as absorbing blue light or ultraviolet light and converting it into green light and emitting it. Materials that emit light, materials that absorb blue light or ultraviolet light and convert it into red light and emit it, A material that absorbs ultraviolet light and converts it into blue light, which is then emitted, can be used in the color conversion layer. In essence, quantum dots with a diameter of several nanometers can be used in the color conversion layer. This allows for half-maximum It can emit light with a narrow spectrum, or it can emit highly saturated light. Cut.

[0216] 《Example 4 of the composition of layer 553(j) containing luminescent material.》 For example, the light-emitting unit can be used in layer 553(j) containing a light-emitting material. The unit consists of one region where electrons injected from one side recombine with holes injected from the other side. It is equipped with a light-emitting unit, and the light-emitting material contains an electron-hole recombination. The energy generated is released as light.

[0217] For example, multiple light-emitting units and an intermediate layer are used in layer 553(j) which contains a light-emitting material. This is possible. The intermediate layer comprises a region sandwiched between the two light-emitting units. The intermediate layer is electric It has a charge generation region, and the intermediate layer supplies holes to the light-emitting unit located on the cathode side, and on the anode side It has the function of supplying electrons to the positioned light-emitting units. Also, multiple light-emitting units and A configuration that includes an intermediate layer is sometimes called a tandem-type light-emitting element.

[0218] This makes it possible to increase the current efficiency related to light emission. Alternatively, at the same brightness, This can reduce the current density flowing through the optical element, or improve the reliability of the light-emitting element. It is possible.

[0219] For example, a light-emitting unit containing a material that emits light of one hue, and a material that emits light of another hue... It can be used in combination with the light-emitting unit to form a layer 553(j) containing a light-emitting material. Alternatively, a light-emitting unit containing a material that emits light of one hue, or a material that emits light of the same hue. It can be used in combination with a light-emitting unit, and in a layer 553(j) containing a light-emitting material. Specifically, two light-emitting units containing a material that emits blue light can be used in combination. Cut.

[0220] By the way, for example, polymer compounds (oligomers, dendrimers, polymers, etc.), medium molecular weight Compounds (compounds in the intermediate region between low molecular weight and high molecular weight: molecular weight between 400 and 4000), etc., emit light. It can be used in layer 553(j) containing a material.

[0221] 《Electrode 551(i,j), electrode 552》 For example, a material that can be used for wiring, etc., can be used for electrode 551(i,j) or electrode 552. It is possible to do so. Specifically, a material that is transparent to visible light is used as electrode 551(i, j) or electrode 552 can be used.

[0222] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium Using tin oxide, indium zinc oxide, zinc oxide, gallium-added zinc oxide, etc. This is possible. Alternatively, a thin metal film that allows light to pass through can be used. A material that is transparent to visible light can be used.

[0223] For example, a metal film that transmits some of the light and reflects other parts of the light is used as the electrode 551(i,j) This can be used in electrode 552. For example, a layer 553(j) containing a luminescent material, etc. This is used to adjust the distance between electrodes 551(i,j) and 552.

[0224] This allows a micro-resonator structure to be provided on the display element 550(i,j). This allows for the extraction of light of a specific wavelength more efficiently than other light. Alternatively, half of the spectrum It is possible to extract light with a narrow price range, or to extract light with vivid colors. .

[0225] For example, a film that efficiently reflects light can be used for electrode 551(i,j) or electrode 552. This can be done. Specifically, materials containing silver and palladium, etc. or materials containing silver and copper, etc. The material can be used on electrode 551(i,j) or electrode 552.

[0226] Furthermore, electrode 551(i,j) is connected to pixel circuit 530(i,j) at aperture 591A. They are electrically connected (see Figure 3A). Electrode 551(i,j) is formed in the insulating film 528. Overlapping with the opening, electrode 551(i,j) is provided with an insulating film 528 around its periphery.

[0227] This prevents short circuits between electrodes 551(i,j) and 552.

[0228] 《Example of display area 231 configuration 1.》 The display area 231 comprises multiple pixels. For example, multiple pixels that display colors with different hues. These pixels can be used in the display area 231.

[0229] This allows the colors displayed by the multiple pixels to be mixed additively or subtractively. Alternatively, it can display hues that cannot be displayed by individual pixels.

[0230] Furthermore, when using multiple pixels that display colors with different hues for color mixing, each These pixels can be referred to as subpixels. Furthermore, multiple subpixels can be grouped together to form a pixel and It can be rephrased.

[0231] For example, pixel 702(i,j) can be rephrased as a subpixel, and pixel 702(i,j) , pixels 702(i,j+1) and 702(i,j+2) are grouped together to form pixel 703 This can be rephrased as (i,k) (see Figure 1C).

[0232] Furthermore, for example, pixel 702(i,j) can be rephrased as a subpixel, and pixel 702(i ,j), pixel 702(i,j+1), pixel 702(i+1,j) and pixel 702(i+ We can rephrase this as pixel 703(i,k) by taking 1,j+1) as a pair (Figure 1D). (See Figure 1E).

[0233] Specifically, subpixels that display blue, subpixels that display green, and subpixels that display red These can be used as a pair for pixel 703(i,k). Additionally, a sub-display for cyan can be used. A pixel, a sub-pixel that displays magenta, and a sub-pixel that displays yellow are grouped together as a pixel 7 It can be used with 03(i,k).

[0234] Furthermore, for example, sub-pixels that display white or other colors can be used in addition to the above set of pixels. ru.

[0235] 《Example 2 of the display area 231 configuration.》 Display area 231 includes pixels 702(i,j), 702(i,j+1), and 702 It has (i, j+2) (see Figure 1C).

[0239] Also, pixels 702(i,j), 702(i,j+1), and 702(i,j+2 ) is the area ratio of the CIE chromaticity diagram (x,y) to the BT.2020-2 standard color gamut. It is preferable to have a coverage rate of 80% or more, or 75% or more for the color gamut. The area ratio should be 90% or more, or the coverage rate should be 85% or more.

[0241] This embodiment can be appropriately combined with other embodiments shown herein. .

[0242] (Embodiment 2) In this embodiment, a method for manufacturing a display panel according to one aspect of the present invention is shown in Figures 6 to 10. I will explain while referring to it.

[0243] Figures 6 to 10 are cross-sectional views illustrating a method for manufacturing a display panel according to one embodiment of the present invention.

[0244] <Method for manufacturing display panel 700> The method for manufacturing a display panel described in this embodiment comprises the first to fifth steps. It has (see Figure 6). In this embodiment, the formation of the auxiliary wiring 554 is followed by the formation of the conductive film 57 The method for creating part 4 will be explained.

[0245] [Step 1] In the first step, auxiliary wiring 554 is formed (see Figure 6(W1) and Figure 7A). Furthermore, in the process of forming the auxiliary wiring 554, for example, the electrode 551(i,j) is formed. It is possible.

[0246] Specifically, a conductive film 551A having a high reflectivity to visible light, and a high reflectivity to visible light A laminated film, which consists of a conductive film having transmittance and a laminated film, is subjected to a predetermined method using photolithography. To process into shape.

[0247] Furthermore, by using a conductive film processed into a predetermined shape as a mask, the insulating film 521 is etched. This can be done (see Figure 7B). For example, if a polymer material such as polyimide is used for the insulating film 521 Then, the insulating film 521 is processed into a predetermined shape using the ashing method. A step can be formed along the outer circumference of electrode 551(i,j). Also, auxiliary wiring 5 A step can be formed along the outer circumference of 54.

[0248] Furthermore, an insulating film 528 is formed. Specifically, an insulating film is formed to cover the electrodes 551(i,j). Then, using photolithography, an opening is formed in the region overlapping with electrode 551(i,j). (See Figure 8A).

[0249] [Step 2] In the second step, the display element 550(i,j) is formed (Figure 6(W2) and Figure 6(W2) (See 8B). Specifically, a layer 553(j) containing a light-emitting material is placed on the electrode 551(i,j). The electrode 552 is formed on a layer 553(j) containing a light-emitting material.

[0250] Furthermore, the insulating film 528 is located around the electrode 551(i,j) This prevents short circuits in electrode 552.

[0251] Furthermore, on the side of the auxiliary wiring 554, the thickness of the layer 553(j) containing the luminescent material is thin. This can occur. This results in the electrical connection of electrode 552 and auxiliary wiring 554. It is possible.

[0252] [Step 3] In the third step, an insulating film 573 is formed (see Figure 6(W3) and Figure 9A). Specifically, the insulating film 573 is produced using methods such as vapor deposition, sputtering, or chemical vapor deposition. It forms.

[0253] For example, an insulating film 573A is formed on the electrode 552 using chemical vapor deposition, and atomic layer deposition is performed. Using this method, insulating film 573B is laminated on insulating film 573A.

[0254] Furthermore, the insulating film 573 can suppress the diffusion of impurities to the display element 550(i,j). This allows the resist 30 to be formed on the insulating film 573.

[0255] [Step 4] In the fourth step, the opening 552H is formed (see Figures 6(W4) and 9B). Specifically, using a dry etching method, the insulating film 573, electrode 552, and luminescent material are removed. The layer 553(j) containing is processed.

[0256] For example, an opening is formed in the insulating film 573 using a fluorine-containing gas. Also, for example, An opening is formed in the electrode 552 using a gas containing chlorine or methane. Furthermore, for example, an opening can be formed in the layer 553 containing the luminescent material using an oxygen-containing gas. Note that a portion of the auxiliary wiring 554 may be removed.

[0257] Furthermore, after forming the opening 552H, the resist 30 is processed into a predetermined shape (see Figure 9B). Specifically, the edges of the resist 30 can be recessed using the ashing method. This allows the opening of the resist 30 to be widened. Also, the thickness of the resist 30 To reduce the amount of flavor.

[0258] For example, a thin region is formed on the resist 30 using a single photomask. In general, the photosensitive resin is processed using a gray tone mask or halftone mask, etc. This allows, for example, the formation of regions with different exposure levels in a positive-type photosensitive resin. Alternatively, a single photomask can be used to create a resist 30 with regions of different thicknesses. It can be formed.

[0259] Using the resist 30 processed into a predetermined shape, an opening 573H is formed in the insulating film 573. (See Figure 10A). This makes the area of ​​opening 552H smaller than the area of ​​opening 573H. It can be cut.

[0260] [Step 5] In the fifth step, a conductive film 574 is formed (see Figure 6(W5) and Figure 10B). For example, a conductive film 574 is formed using the sputtering method. This forms the conductive film 57 4 can be electrically connected to electrode 552. Alternatively, a conductive film 574 can be formed using an etching method or the like. Without processing, the auxiliary wiring 554 and electrode 552 are electrically connected at a predetermined position. Alternatively, the area in contact between the conductive film 574 and the electrode 552 can be increased.

[0323] Furthermore, multiple types of detection elements can be used in combination. For example, a detection element that detects fingers and It can be used in conjunction with a detection element that detects a stylus pen.

[0324] This allows us to determine the type of pointer. Or, the type of pointer that has been determined. Based on this, different instructions can be associated with detection information. Specifically, to the pointer If it is determined that a finger was used, the detection information can be associated with the gesture. If it is determined that a stylus pen was used for the pointer, the detection information is associated with the drawing process. It is possible to do so.

[0325] Specifically, a proximity sensor using a capacitive, pressure-sensitive, or optical method is used to detect a finger. Alternatively, a stylus can be used with an electromagnetic induction or optical proximity sensor. It can detect a pen.

[0326] 《Example configuration of input unit 240 2.》 The input section 240 includes an oscillator circuit OSC and a detection circuit DC (see Figure 13).

[0327] The oscillator circuit OSC supplies a search signal to the detection element 775(g,h). For example, a square wave, Sawtooth waves, triangular waves, sine waves, etc., can be used as search signals.

[0328] The detection element 775(g,h) is the distance to the pointer adjacent to the detection element 775(g,h). It also generates and supplies a detection signal that changes based on the search signal.

[0329] The detection circuit DC supplies input information based on the detection signal.

[0330] This makes it possible to detect the distance from the adjacent pointer to the detection area 241. Alternatively, the position where the pointer is closest within the detection area 241 can be detected. .

[0331] 《Example 2 of the display area 231 configuration.》 The display area 231 is located on the side of the detection area 241 that is closer to the pointer, and the display area 231 It is flexible (see Figures 14A and 14B). Also, for example, the arrangement of the keyboard The image shown can be displayed in the display area 231 (see Figure 14A).

[0332] 《Example of detection element configuration 2.》 The detection element 775(g,h) has the function of detecting the amount of indentation, and the detection element 775(g,h The pointer is detected via the display area 231 (see Figure 14B).

[0333] For example, the amount by which the pointer is pushed toward the sensing element 775(g,h) is detected by the sensing element 77 5(g,h) is detected. Specifically, the detection area 241 is detected from the plane containing the display area 231. The amount of pressure applied to the included surface by the detection element 775(g,h) It detects (see Figure 14C).

[0334] For example, a pressure sensor can be used as the sensing element 775(g,h). Specifically, An element whose electrical resistance changes in response to force can be used as the sensing element 775(g,h). (See Figure 14D). As a result, the detection element 775(g,h) can detect the amount of indentation. can.

[0336] 《Example of the configuration of component 249》 Component 249 overlaps with the detection area 241 and is elastic.

[0337] For example, an elastic material can be used as member 249. Specifically, a spring, leaf spring, rubber, etc. Alternatively, you can use a sponge or similar material.

[0338] This allows the detection element 775(g,h) to detect the amount of indentation. Alternatively, The user can feel the force corresponding to how much they press the pointer.

[0339] Furthermore, for example, a structure that buckles when jumping can be used in member 249. Specifically, A dome-shaped or other structure can be used for member 249 (see Figure 15B).

[0340] Member 249 has a mode 1 that is stable in the region of small strain, and a mode 1 that is stable when the strain ε is large. It also features a stable mode 2 in the low region (see Figures 15C and 15D). Member 249 jumps from mode 1 to mode 2 at the buckling point. (See Figure 15D). Also, by removing the strain, mode 2 can be changed to mode m It reversibly jumps to ode1.

[0341] As a result, the detection element 775(g,h) detects the amount of indentation up to the buckling point. A force σ corresponding to this can be detected. Alternatively, the user can perceive it as a tactile sensation. Alternatively, the user can feel a click when exceeding the buckling point. A tactile switch can be provided to release the pointer pressed by the user. By releasing the material, the structure that buckles upon jumping can return to its original mode.

[0342] Furthermore, a detection area 241 is provided superimposed on the structure that undergoes jumping buckling, and superimposed on the detection area 241 A display area 231 is provided, and the image used for operation is positioned to overlap with the jumping and buckling structure. It can be displayed. For example, a layout that is preferably used for a keyboard, jumping and buckling It can be used in the arrangement of a structure that does this. Or, an arrangement that is preferably used for a home button. This can be used in the arrangement of structures that buckle when jumping between them.

[0343] This allows you to press down on the image used for the displayed operation. Or, press down As a result, the user can experience a click sensation.

[0344] Alternatively, member 2 has an area where multiple structures that perform jump-and-buckle are provided across its entire surface. 49 can be used. A detection area 241 is provided superimposed on the said area, and in the detection area 241 An additional display area 231 is provided, and an image for operation is provided across the entire structure. It can be displayed in a position that overlaps with the area.

[0345] This allows the image used for operations that provide a click sensation when pressed to be used for itself It can be positioned as desired.

[0346] The detection unit 250 may be placed on top of the input / output device described in this embodiment. For example, a pressure-sensitive switch can be used in the detection unit 250. Specifically, a conductive material can be used. A dome-shaped structure that buckles upon jumping is used, and the dome-shaped structure is used as the contact of a pressure-sensitive switch. It can be used for this purpose. This makes it possible to provide a so-called membrane switch. Alternatively, a switch with a click feel can be provided. Or, a so-called tactile switch. It is possible to add a switch.

[0368] For example, a human interface can be used in the input unit 240 (Figure 16A). (See reference). Specifically, input devices include keyboards, mice, touch sensors, microphones, or cameras. It can be used in part 240.

[0369] Furthermore, a touch sensor having an area that overlaps with the display unit 230 can be used. An input / output device equipped with a touch sensor having an area overlapping the display unit 230 and the display unit 230, It can be called a touch panel or touchscreen.

[0370] For example, the user can use their finger touching the touch panel as a pointer to perform various gestures ( You can perform actions such as tapping, dragging, swiping, or pinching in.

[0371] For example, the arithmetic unit 210 analyzes information such as the position or trajectory of a finger that is in contact with the touch panel. And, when the analysis results satisfy predetermined conditions, it is assumed that a predetermined gesture has been supplied. Yes, it is possible. This allows the user to use a predetermined gesture that is pre-associated with a given gesture. Operation commands can be supplied using the gesture.

[0380] Furthermore, these configurations cannot be clearly separated, and one configuration may also serve as another configuration. This may include a part of it. For example, a touch panel in which a touch sensor is superimposed on the display panel is It serves as both a display unit and an input unit.

[0381] 《Example of the configuration of the arithmetic unit 210.》 The computing unit 210 includes an artificial intelligence unit 213 (see Figure 16A).

[0382] The artificial intelligence unit 213 is supplied with input information II or detection information DS, and the artificial intelligence unit 213 receives input Based on force information II or detection information DS, control information CI is inferred. Also, the artificial intelligence department... 213 supplies control information CI.

[0383] This allows for the generation of control information CIs that are displayed in a way that is perceived as favorable. It can be displayed in a way that makes it seem preferable or comfortable. It is possible to generate control information CIs that are displayed in a way that makes it feel comfortable. It can be displayed in a way that makes it feel like it is easy to use. As a result, it can be a new product that is convenient or reliable. We can provide an information processing device.

[0384] [Natural language processing on input information II] Specifically, the artificial intelligence unit 213 performs natural language processing on the input information II, and then processes the entire input information II. One feature can be extracted from the input information II. For example, the artificial intelligence unit 213 takes the input information II into account. It is possible to infer and define the emotions and other factors that have been observed as characteristics. Furthermore, it is possible to empirically determine which characteristics are suitable. It can infer the colors, patterns, or fonts that are perceived. Also, Artificial Intelligence Unit 213 This generates information that specifies the color, pattern, or font of the text, and information that specifies the color or pattern of the background. This can be used for control information CI.

[0385] Specifically, the artificial intelligence unit 213 performs natural language processing on the input information II and extracts the information contained in the input information II. It is possible to extract some of the words. For example, the artificial intelligence unit 213 can extract grammatical errors, It can extract misrepresentations or expressions containing emotions. In addition, the artificial intelligence unit 213 extracts Generate and control information that displays a portion of the output in a different color, pattern, or font from other portions. It can be used for informational corporate identity (CI).

[0386] [Image processing for input information II] Specifically, the artificial intelligence unit 213 processes the input information II as an image and extracts one from the input information II. Features can be extracted. For example, the artificial intelligence unit 213 can extract input information II from a photograph. Age, indoor or outdoor location, day or night, etc. can be inferred and used as characteristics. Infer a color tone that is empirically perceived as suitable, and control information for using that color tone in display. It is possible to generate a CI (Critical Information). Specifically, it can generate the colors used to represent shades of gray (for example, full color). Information specifying (such as black and white or brownish-red) can be used in the control information CI.

[0387] Specifically, the artificial intelligence unit 213 processes the input information II as an image, and the input information II contains It is possible to extract a portion of an image. For example, a boundary can be placed between a portion of the extracted image and another portion. It is possible to generate control information CI that displays a portion of the extracted image. Specifically, it is possible to surround a portion of the extracted image. It is possible to generate control information CIs that display a rectangle.

[0388] [Inference using detection information DS] Specifically, the artificial intelligence unit 213 can generate inferences using the detection information DS. Alternatively, based on reasoning, so that the user of the information processing device 200 feels comfortable. It can generate control information CI.

[0389] Specifically, based on the ambient illuminance, the artificial intelligence unit 213 determines that the display brightness is comfortable. It is possible to generate control information CI to adjust the display brightness so that it feels like the display is brighter. Alternatively, the artificial intelligence unit 213 determines that the size is perceived as comfortable based on environmental noise, etc. This allows for the generation of control information (CI) to adjust the volume.

[0390] The display unit 230 supplies a clock signal or timing signal to the control unit 238. These can be used in the control information CI. Alternatively, the control unit 248 provided in the input unit 240 The clock signal or timing signal supplied to the control information CI can be used. .

[0391] <Example of information processing device configuration 2.> For another configuration of an information processing device according to one aspect of the present invention, refer to Figures 17A and 17B. Let me explain.

[0392] "program" A program according to one aspect of the present invention has the following steps (see Figure 17A).

[0393] [Step 1] In the first step, the settings are initialized (see Figure 17A(S1)).

[0394] For example, predetermined image information to be displayed at startup, and a predetermined mode for displaying said image information, Information specifying a predetermined display method for displaying the image information is obtained from the storage unit 212. Specifically, this involves using one still image or another moving image to create a predetermined image. Yes, it is possible. Furthermore, the first mode or the second mode can be used as a predetermined mode.

[0395] [Step 2] In the second step, interrupt handling is enabled (see Figure 17A(S2)). An arithmetic unit authorized to perform interrupt processing can perform interrupt processing in parallel with the main processing. The arithmetic unit, having returned to the main process from the interrupt handling, then uses the result obtained from the interrupt handling as the main process. This can be reflected in the processing.

[0396] Furthermore, when the counter value is at its initial value, the arithmetic unit is prompted to perform an interrupt. When returning from the program, the counter may be set to a value other than its initial value. This allows the program to... It is possible to have interrupt processing always run after startup.

[0397] [Step 3] In the third step, a predetermined selected in the first step or interrupt processing. The image information is displayed using the mode or a predetermined display method (see Figure 17A(S3)). The specified mode identifies the mode for displaying information, and the specified display method displays image information. Identify the method for doing so. Also, for example, it can be used for information that displays image information VI. .

[0398] For example, one method of displaying image information VI can be associated with a first mode. Alternatively, other methods for displaying image information VIs can be associated with the second mode. This allows you to select the display method based on the selected mode.

[0399] Mode 1 Specifically, a selection signal is supplied to one scan line at a frequency of 30 Hz or higher, preferably 60 Hz or higher. A method of supplying and displaying based on a selection signal can be associated with the first mode.

[0400] For example, if a selection signal is supplied at a frequency of 30 Hz or higher, preferably 60 Hz or higher, the moving image It can display the movement smoothly.

[0401] For example, if the image is updated at a frequency of 30Hz or higher, preferably 60Hz or higher, the user's operation The image changes to smoothly follow the user's actions and is displayed on the information processing device 200 that the user is operating. It can be shown.

[0402] 《Second Mode》 Specifically, a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. A method of supplying a selection signal to one scan line at a time and displaying based on the selection signal is called a second mode. It can be associated with "do".

[0403] A selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. By supplying this, a display with reduced flicker or blinking can be achieved. Also, Power consumption can be reduced.

[0404] For example, if the information processing device 200 is used as a clock, it will be used at a frequency of once per second or once per minute. The display can be updated based on frequency, etc.

[0405] By the way, for example, when using a light-emitting element as a display element, the light-emitting element is made to emit light in a pulsed manner. This allows for the display of image information. Specifically, by emitting light from an organic EL element in a pulsed manner... The afterglow can be used for display. Organic EL elements have excellent frequency characteristics. In some cases, this can reduce power consumption by shortening the time required to drive the light-emitting element. Because heat generation is suppressed, it may be possible to reduce the degradation of the light-emitting element.

[0406] [Step 4] In the fourth step, if a termination command is supplied, proceed to the fifth step, and the termination command If it is not supplied, choose to proceed to the third step (see Figure 17A(S4)). ).

[0407] For example, the termination instruction supplied during interrupt handling may be used for the decision.

[0408] [Step 5] In the fifth step, the process ends (see Figure 17A(S5)).

[0409] Interrupt handling Interrupt handling comprises the following steps 6 through 8 (see Figure 17B).

[0410] [Step 6] In the sixth step, for example, the information processing device 200 is used with the detection unit 250. The illuminance of the environment is detected (see Figure 17B(S6)). Note that instead of illuminance of the environment, ambient light The color temperature and chromaticity may also be detected.

[0411] [Step 7] In the seventh step, the display method is determined based on the detected illuminance information (Figure 17B( See S7). For example, set the display brightness so that it is not too dark or too bright. To determine.

[0412] Furthermore, if the color temperature or chromaticity of the ambient light is detected in step 6, the display will You can adjust the color.

[0413] [Step 8] In the eighth step, the interrupt processing is terminated (see Figure 17B(S8)).

[0414] <Example of information processing device configuration 3.> Another configuration of an information processing device according to one aspect of the present invention will be described with reference to Figure 18.

[0415] Figure 18A is a flowchart illustrating a program according to one embodiment of the present invention. This is a flowchart explaining an interrupt process different from the interrupt process shown in Figure 17B. .

[0416] In addition, the configuration example 3 of the information processing device changes the mode based on a predetermined event that is supplied. The interrupt handling process has a step that can be explained with reference to Figure 17B. This is different from logic. Here, we will explain the differences in detail and how to use a similar structure. I will use the above explanation for the parts that I can do.

[0417] Interrupt handling Interrupt processing comprises the following steps 6 through 8 (see Figure 18A).

[0418] [Step 6] In step 6, if a predetermined event is supplied, proceed to step 7. If the specified event is not supplied, proceed to step 8 (see Figure 18A(U6)). (See reference). For example, it can be used as a condition to determine whether or not a specific event was supplied during a specified period. It can be done. Specifically, 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less. This means that a period longer than 0 seconds can be defined as the predetermined period.

[0419] [Step 7] In the seventh step, the mode is changed (see Figure 18A(U7)). Specifically, If you selected mode 1, then select mode 2, and if you selected mode 2 In that case, select the first mode.

[0420] For example, the display mode can be changed for a portion of the display unit 230. In particular, the display unit 230 includes drive circuits GDA, GDB, and GDC. The display mode can be changed in the region where one drive circuit supplies the selection signal. (See Figure 18B).

[0421] For example, in the input section 240 located in the region where the drive circuit GDB supplies the selection signal, When a predetermined event is supplied, the drive circuit GDB supplies a selection signal to the display area. The code can be changed (see Figures 18B and 18C). Specifically, by using your finger, etc. The GDB drive circuit provides a selection in response to the "tap" event supplied to the touch panel. The frequency of the signal can be changed.

[0422] The signal GCLK is a clock signal that controls the operation of the drive circuit GDB, and the signal PWC Signals 1 and PWC2 are pulse width control signals that control the operation of the drive circuit GDB. The GDB circuit selects a signal based on signals GCLK, PWC1, PWC2, etc. This is supplied to scan line G2(m+1) or scan line G2(2m).

[0423] This means, for example, that the drive circuit GDA and drive circuit GDC supply selection signals. The drive circuit GDB can supply the selection signal. Alternatively, the drive circuit GDA and Without changing the display in the area where the drive circuit GDC supplies the selection signal, the drive circuit GDB selects The display of the area supplying the selection signal can be updated. Alternatively, the power consumed by the drive circuit can be updated. It can be suppressed.

[0424] [Step 8] In the eighth step, the interrupt processing is terminated (see Figure 18A(U8)). Interrupt handlers may be repeatedly executed during the period in which this process is being performed.

[0425] 《Scheduled Events》 For example, "clicks" and "drags" that are supplied using a pointing device such as a mouse. Events such as using a finger or other object as a pointer to input data to a touch panel, such as "tap" and "drag". Events such as "grab" or "swipe" can be used.

[0426] Also, for example, the position of the slider bar pointed to by the pointer, the swipe speed, the drag speed. Arguments to commands associated with a given event can be provided using degrees, etc.

[0427] For example, the information detected by the detection unit 250 is compared with a pre-set threshold, and the comparison result It can be used for events.

[0428] Specifically, a pressure sensor that contacts buttons or other objects positioned to be pressed into the casing. These can be used in the detection unit 250.

[0429] 《Instructions to associate with a specified event》 For example, a termination command can be associated with a predetermined event.

[0430] For example, "page turning" is used to switch the displayed image information from one image to another. The "page turn command" can be associated with a predetermined event. Arguments that determine the page-turning speed used during execution are set using a predetermined event. It can be given.

[0431] For example, move the display position of a portion of an image to create a continuous section within that portion. You can associate commands such as "scroll commands" that display other parts with specific events. This determines the speed at which the display moves when executing the "scroll command". Arguments can be provided using a predetermined event.

[0432] For example, commands to set the display method or commands to generate image information are sent to a predetermined event It can be associated with a predetermined event. It can be associated with the . Also, the argument that determines the brightness of the generated image is set by the detection unit 2 50 may be determined based on the ambient brightness detected by the sensor.

[0433] For example, information delivered using a push-type service can be acquired using the communication unit 290. Commands and other instructions can be associated with specific events.

[0459] This embodiment can be appropriately combined with other embodiments shown herein. .

[0460] For example, in this specification, etc., if it is explicitly stated that X and Y are connected The cases are when X and Y are electrically connected and when X and Y are functionally connected. The cases disclosed in this specification, etc., include the case where X and Y are directly connected. Therefore, the connection relationships are not limited to those shown in the diagram or text. In addition to the connections shown in the diagrams or text, other connections are also disclosed in the diagrams or text. do.

[0461] Here, X and Y are the object (e.g., device, element, circuit, wiring, electrode, terminal, conductive film, layer). (etc.)

[0462] One example of a case where X and Y are directly connected is when an electrical connection between X and Y is possible. Elements such as switches, transistors, capacitive elements, inductors, resistive elements, and dies. If the diode, display element, light-emitting element, load, etc. are not connected between X and Y and elements that enable electrical connection between X and Y (e.g., switches, transistors, capacitors) Without the need for elements such as components, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc. This is the case when X and Y are connected.

[0463] One example of a case where X and Y are electrically connected is the ability to make an electrical connection between X and Y possible. Elements such as switches, transistors, capacitive elements, inductors, resistive elements, and dies. One or more devices (such as diodes, display elements, light-emitting elements, and loads) are connected between X and Y. Yes, it is possible. Furthermore, a switch has the function of being controlled to be on or off. In other words, a switch The switch can be in a conductive (on) or non-conductive (off) state, allowing current to flow. It has a function to control whether or not current flows. Alternatively, the switch selects the path through which current flows. It has a function to switch between them. Furthermore, if X and Y are electrically connected, X and This includes cases where Y is directly connected to it.

[0464] One example of a functional connection between X and Y is enabling a functional connection between X and Y. Circuits that perform this function (for example, logic circuits (inverters, NAND gates, NOR gates, etc.), signal transformers) Conversion circuits (DA conversion circuits, AD conversion circuits, gamma correction circuits, etc.), potential level conversion circuits (electric (Source circuits (boost circuits, buck circuits, etc.), level shifter circuits that change the potential level of a signal, etc.) Voltage source, current source, switching circuit, amplification circuit (which can increase signal amplitude or current amount, etc.) Circuits, operational amplifiers, differential amplifier circuits, source follower circuits, buffer circuits, etc., signal generation One or more circuits (such as memory circuits and control circuits) can be connected between X and Y. For example, even if another circuit is placed between X and Y, the signal output from X If the signal is transmitted to Y, then X and Y are assumed to be functionally connected. When X and Y are functionally connected, the situation is different from when X and Y are directly connected. This includes cases where and are electrically connected.

[0465] Furthermore, if it is explicitly stated that X and Y are electrically connected, then X and Y and When they are electrically connected (i.e., when there is another element or circuit between X and Y) (when connected) and when X and Y are functionally connected (i.e., X and Y are connected) (When functionally connected with another circuit in between) and when X and Y are directly connected In the case of (that is, when X and Y are connected without another element or circuit in between) and However, this shall be as disclosed in this specification, etc. That is, explicitly stated that they are electrically connected. If it is explicitly stated that it is connected, then Similar information is disclosed in this specification, etc.

[0466] For example, if the source (or first terminal, etc.) of the transistor is connected via Z1 (or via (In short), electrically connected to X, the drain (or second terminal, etc.) of the transistor is connected to Z. If Y is electrically connected via (or without) 2, or if the transistor source (or the first terminal, etc.) is directly connected to a part of Z1, and another part of Z1 is directly connected to X. They are directly connected, with the transistor's drain (or second terminal, etc.) directly connected to a portion of Z2. If it is connected to and another part of Z2 is directly connected to Y, it can be expressed as follows: It is possible to do so.

[0467] For example, "X and Y and the source (or first terminal, etc.) and drain (or second terminal) of the transistor." The terminals (such as the X terminal) are electrically connected to each other, and X is the source (or the X terminal) of the transistor. The electrical connections are in the following order: terminal 1, the drain of the transistor (or terminal 2, etc.), and Y. It can be expressed as "It is connected." Or, "The source (or the source) of the transistor." Terminal 1 (or terminal 2) is electrically connected to X, and the drain (or terminal 2) of the transistor is connected to X. (d) is electrically connected to Y, X is the source of the transistor (or the first terminal, etc.), and the transistor The drain (or second terminal, etc.) of the converter, Y, is electrically connected in this order. It can be expressed as "X is the source (or first terminal) of the transistor." Alternatively, "X is the source (or first terminal) of the transistor." Y is electrically connected to X via the drain (or second terminal, etc.) and X, the transistor The source of the transistor (or the first terminal, etc.), the drain of the transistor (or the second terminal, etc.) ), Y is provided in this connection order. By using a specific method of expression to define the order of connections in the circuit configuration, Distinguish between the source (or first terminal, etc.) and drain (or second terminal, etc.) of the zista. This allows us to determine the technical scope.

[0468] Alternatively, another way to express it is, for example, "the source (or first terminal, etc.) of the transistor." It is electrically connected to X via at least a first connection path, and the first connection path is It does not have a second connection path, and the aforementioned second connection path is via a transistor, The source (or first terminal, etc.) of the transistor and the drain (or second terminal, etc.) of the transistor. The path between ( and ), and the first connection path is a path via Z1, and the transit The drain (or second terminal, etc.) of the terminal is connected to Y and electrical via at least a third connection path. They are connected in a manner, and the third connection path does not have the second connection path, and the third The connection path is the path via Z2. This can be expressed as "The transition The source of the starter (or the first terminal, etc.) is connected via Z1 through at least the first connection path. And, electrically connected to X, 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 of the transistor (or a second terminal, etc.) is connected to Y via Z2 by at least a third connection path. It is expressed as: "They are electrically connected, and the third connection path does not have the second connection path." It is possible. Or, "the source (or first terminal, etc.) of the transistor is less Both are electrically connected to X via Z1 through a first electrical path, and the first electrical The target path does not have a second electrical path, and the second electrical path is the transistor From the source (or first terminal, etc.) to the drain (or second terminal, etc.) of the transistor It is an electrical path, and the drain (or second terminal, etc.) of the transistor is at least third The electrical path is electrically connected to Y via Z2, and the third electrical path is , it does not have a fourth electrical path, and the fourth electrical path is the drain of the transistor The electrical pulse from (or the second terminal, etc.) to the source (or the first terminal, etc.) of the transistor It can be expressed as "It is S." Using similar methods of expression as these examples, the circuit configuration By defining the connection path in the transistor, the source (or first terminal) To distinguish between the drain (or second terminal, etc.) and the second terminal, and to determine the technical scope. It is possible.

[0469] Note that these methods of expression are just examples and are not limited to these methods. Here, X Y, Z1, and Z2 are the objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, etc.) Let's assume it is a layer, etc.

[0470] Note that, in circuit diagrams, independent components are shown as being electrically connected to each other. Even in such cases, one component may possess the functions of multiple components. For example, if part of the wiring also functions as an electrode, one conductive film will perform the function of the wiring, and It possesses the functions of both components of the electrode's function. Therefore, the electrode in this specification A conductive connection is a situation where a single conductive film combines the functions of multiple components. Combined forms are also included in that category. [Explanation of Symbols]
