For example, the variables m and m, which take integer values ​​of 1 or more, and variable n, is a part of a code that identifies one of up to m × n components. It may be used in parts.

[0074] <Configuration Example 1 of Display Panel 700> The display panel 700 described in this embodiment has a display region 231 (see FIG. 1A). ).

[0076] Pixel 702(i,j) emits light with a spectrum having a maximum at wavelength λ(1) (see FIG. 2). (See (B)). For example, it emits blue light with a spectrum that has a maximum at wavelength λ(1). The vertical axis on the left side uses arbitrary units, and the emission spectrum is shown schematically by a solid line.

[0077] Pixel 702(i,j+1) emits light with a spectrum that has a maximum at wavelength λ(2). For example, it emits green light with a spectrum that has a maximum at wavelength λ(2).

[0078] Pixel 702(i,j+2) emits light with a spectrum that has a maximum at wavelength λ(3). For example, it emits red light with a spectrum that has a maximum at wavelength λ(3).

[0079] <<Filter MBP Configuration Example 1>> The filter MBP is a region overlapping with pixel 702(i,j), a region overlapping with pixel 702(i,j+1), and a region overlapping with pixel 702(i,j+2). It has an overlapping area and an overlapping area with pixel 702(i,j+2).

[0080] The MBP filter has a transmittance spectrum with minima at wavelengths λ(4) and λ(5). (See Figure 2(B)). The transmittance spectrum is plotted as This is shown diagrammatically by a dashed line.

[0081] Wavelength λ(2) is longer than wavelength λ(1), and wavelength λ(3) is longer than wavelength λ(2).

[0082] Wavelength λ(4) is between wavelength λ(1) and wavelength λ(2), and wavelength λ(5) is between wavelength λ(2 ) and wavelength λ(3).

[0083] For example, a multi-bandpass filter can be used for filter MBP, or A multi-notch filter can be used for the filter MBP. The dashed line shows a schematic diagram of the spectrum of light transmitted through the filter MBP, using arbitrary units. .

[0084] This makes it possible to narrow the width of the spectrum that has a maximum at wavelength λ(1). can narrow the width of the spectrum that has a maximum at wavelength λ(2). The width of the spectrum with a maximum at λ(3) can be narrowed. It is possible to cut off the tail of the spectrum that has a maximum at wavelength λ(2). Or, we can cut off the tail of the spectrum with a maximum at wavelength λ(3). Alternatively, the pixels 702(i,j) to 703(i,j) can be cut off. 02(i,j+2) can make the displayed color vivid. As a result, it is convenient and useful. It is possible to provide a novel display panel having excellent performance and reliability. The blue light becomes brighter when the tint is removed (see Figure 2(B)). The green light becomes brighter with the dark and reddish light removed. The red light becomes brighter as the darker light is removed.

[0085] <Filter MBP configuration example 2> The filter MBP is a wavelength band of 20 nm width including the wavelength λ(4), preferably a wavelength band of 30 nm width. In the wavelength band, the transmittance is 0.5 or less, preferably 0.1 or less, and more preferably It has a transmittance of 0.01 or less. In addition, it has a wavelength band of 30 nm including the wavelength λ(5), preferably The filter has a transmittance of 0.5 or less in the wavelength band of 40 nm. is a transmittance of 0.85 or more at wavelength λ(1), wavelength λ(2) and wavelength λ(3), The transmittance is preferably 0.9 or more, and more preferably 0.95 or more.

[0086] Specifically, a filter having a laminated film in which low refractive index layers and high refractive index layers are alternately stacked is called a filter. It can be used for filter MBP. For example, from the transmission band with a transmittance of 0.8 or more, The filter that transitions within 10 nm to a non-transmitting band of 0.1 or less is called the filter MBP. It can be used for.

[0087] This allows the transmittance to change sharply with respect to the wavelength of light. There is no need to change the filter MBP configuration for each pixel that displays color. Therefore, it is possible to provide a novel display panel that is excellent in usability and reliability.

[0097] As a result, the adjustment layer 555(1) and the adjustment layer 555(2) are formed by a photolithography process. Alternatively, a light-emitting material can be formed for each pixel that displays a different color. There is no need to change the composition of the layer 553 containing the material.

[0226] Example 2 of the layer 553(j) containing a light-emitting material For example, a light-emitting unit can be used in layer 553(j) containing a light-emitting material. The unit has one region where electrons injected from one side recombine with holes injected from the other side. The light-emitting unit includes a light-emitting material, and the light-emitting material is a material that allows electrons and holes to recombine. The energy generated by this is released as light.

[0227] For example, multiple light-emitting units and intermediate layers are used in the layer 553(j) containing the light-emitting material. The intermediate layer has a region sandwiched between the two light-emitting units. The intermediate layer supplies holes to the light-emitting unit disposed on the cathode side and It has a function of supplying electrons to the light-emitting units arranged therein. A configuration including a light-emitting layer and an intermediate layer is sometimes called a tandem light-emitting device.

[0228] This makes it possible to increase the current efficiency of light emission. The current density flowing through the optical element can be reduced, or the reliability of the light-emitting element can be improved. can be done.

[0229] For example, a light-emitting unit containing a material that emits light of one hue may be combined with a material that emits light of another hue. The layer 553(j) containing the light-emitting material can be used to overlap the light-emitting unit containing the light-emitting material. Alternatively, a light-emitting unit including a material that emits light of one hue may be replaced with a material that emits light of the same hue. The layer 553(j) containing the light-emitting material can be stacked with the light-emitting unit containing the Specifically, two light-emitting units containing blue light-emitting materials can be stacked. Cut.

[0230] By the way, for example, high molecular weight compounds (oligomers, dendrimers, polymers, etc.), compounds (compounds in the intermediate range between low molecular weight and high molecular weight: molecular weight 400 to 4000) The layer 553(j) may be made of a material containing a crystalline polymer.

[0231] 《Electrode 551(i,j), electrode 552》 For example, a material that can be used for wiring or the like is used for the electrode 551(i, j) or the electrode 552. Specifically, a material that is transparent to visible light can be used for the electrodes 551 (i, j) or electrode 552.

[0232] For example, conductive oxides or conductive oxides containing indium, indium oxide, indium Indium tin oxide, indium zinc oxide, zinc oxide, zinc oxide doped with gallium, etc. Alternatively, a metal film thin enough to transmit light can be used. A material that is transparent to visible light can be used.

[0233] For example, a metal film that transmits part of the light and reflects the other part of the light may be used as the electrode 551(i, j) or can be used for the electrode 552. For example, a layer 553(j) containing a light-emitting material can be used for the electrode 552. is used to adjust the distance between electrode 551(i,j) and electrode 552.

[0234] This allows a microresonator structure to be provided in display element 550(i,j). This allows light of a specific wavelength to be extracted more efficiently than other light. It is possible to extract light with a narrow value range, or to extract light with vivid colors. .

[0235] For example, a film that efficiently reflects light can be used for the electrode 551(i, j) or the electrode 552. Specifically, a material containing silver and palladium or a material containing silver and copper can be used. The material can be applied to electrode 551(i,j) or electrode 552.

[0236] The electrode 551(i, j) is connected to the pixel circuit 530(i, j) through the opening 591A. The electrodes 551(i, j) are formed on the insulating film 528. The electrode 551(i, j) overlaps the opening to be formed, and has an insulating film 528 on its periphery.

[0237] This makes it possible to prevent short-circuiting between electrode 551(i,j) and electrode 552.

[0238] <<Configuration Example 2 of Display Area 231>> The display area 231 includes a plurality of pixels. For example, the display area 231 may have a function of displaying colors with different hues. can be used in the display area 231.

[0239] This allows the colors displayed by the plurality of pixels to be mixed by additive or subtractive color mixture. Alternatively, it is possible to display colors of hues that cannot be displayed by individual pixels.

[0240] In addition, when a plurality of pixels that display colors with different hues are used for color mixing, Each pixel can be called a sub-pixel. This can be rephrased.

[0241] For example, pixel 702(i,j) can be referred to as a subpixel, and pixel 702(i,j) , pixel 702(i,j+1) and pixel 702(i,j+2) are grouped together, and pixel 703 This can be rephrased as (i, k) (see Figure 1(C)).

[0242] For example, pixel 702(i,j) can be referred to as a sub-pixel, and pixel 702(i ,j), pixel 702(i,j+1), pixel 702(i+1,j) and pixel 702(i+ 1, j+1) can be rephrased as pixel 703(i, k) (see FIG. 1(E) )reference).

[0243] Specifically, a sub-pixel that displays blue, a sub-pixel that displays green, and a sub-pixel that displays red can be used as a set for pixel 703(i,k). A pixel, a sub-pixel that displays magenta, and a sub-pixel that displays yellow are grouped together to form a pixel 7 It can be used for 03(i,k).

[0244] Furthermore, for example, a sub-pixel that displays white or the like can be added to the above set and used in the pixel. do.

[0295] <Example 1 of input / output device configuration> The input / output device described in this embodiment has an input unit 240 and a display unit 230 (see FIG. 9).

[0296] 《Display section 230》 The display unit 230 includes a display panel. The display panel 700 can be used as the display unit 230. The configuration having the section 230 can be called an input / output panel 700TP.

[0297] <<Configuration Example 1 of Input Unit 240>> The input unit 240 has a detection area 241. The input unit 240 is adjacent to the detection area 241. It has the function to detect.

[0298] The sensing region 241 comprises an area that overlaps with the pixel 702(i,j).

[0300] <Configuration example 1 of detection area 241> Sensing region 241 may, for example, comprise one or more sensing elements.

[0301] The sensing region 241 includes a group of sensing elements 775(g,1) through 775(g,q), and another group of detector elements 775(1,h) to 775(p,h). , g is an integer of 1 or more and p or less, h is an integer of 1 or more and q or less, and p and q are 1 or more is an integer.

[0303] In addition, another group of detector elements 775(1,h) to 775(p,h) are detector elements 775(g,h) and arranged in the column direction (the direction indicated by arrow C2 in the figure) that intersects with the row direction. will be done.

[0304] Detector Element The detector element has the function of detecting a nearby pointer, such as a finger or a stylus pen. It can be used for a pointer. For example, a metal piece or coil can be used for a stylus pen. You can be there.

[0305] Specifically, there are capacitive proximity sensors, electromagnetic induction proximity sensors, and optical proximity sensors. A resistive film type proximity sensor or the like can be used as the detection element.

[0306] It is also possible to use multiple types of detection elements in combination. For example, a detection element that detects a finger and a , and a detection element that detects a stylus pen can be used in combination.

[0307] This allows the type of pointer to be determined. Based on this, different instructions can be associated with the sensed information. If it is determined that a finger was used, the detection information can be associated with the gesture. If it determines that a stylus pen is used as a pointer, it associates the detection information with the drawing process. It can be done.

[0312] The detection circuit DC provides input information based on the detection signal.

[0313] This makes it possible to detect the distance from the nearby pointer to the detection area 241. Alternatively, the position to which the pointer is closest within the detection area 241 can be detected. .

[0314] <<Configuration Example 1 of Display Area 231>> The display area 231 is disposed on the side closer to the pointer than the detection area 241. The keyboard is flexible (see Fig. 10(A) and Fig. 10(B)). An image showing the arrangement of the items can be displayed in the display area 231 (see FIG. 10(A)).

The amount of pressure of a finger or stylus pen toward a plane including the surface is detected by the detection elements 775(g, h). is detected (see Figure 10(C)).

[0317] For example, a pressure sensor can be used for the sensing element 775(g, h). An element whose electrical resistance changes depending on the force can be used as the detection element 775(g, h) ( (See FIG. 10(D)). As a result, the detecting element 775(g, h) can detect the amount of depression. This can be done.

[0320] For example, an elastic body can be used for the member 249. Specifically, a spring, a leaf spring, rubber, or the like can be used. Alternatively, a sponge or the like can be used.

[0321] This allows the detection element 775(g, h) to detect the amount of depression. The user can feel the force corresponding to the amount of pressure applied to the pointer.

[0322] Also, for example, a structure that undergoes snap-through buckling can be used for the member 249. A dome-shaped structure or the like can be used for the member 249 (see FIG. 11(B)).

[0323] The member 249 has a stable mode mode1 in the region where the strain is small, and a stable mode mode2 in the region where the strain ε is large. It has a stable mode mode2 in the low region (see Figures 11(C) and 11(D)). ) Also, at the buckling point, the member 249 changes from mode mode 1 to mode mode 2. (See Figure 11(D)). Also, by removing the distortion, mode 2 jumps reversibly from mode 1 to mode 2.

[0324] As a result, the sensing element 775(g, h) detects the amount of pressure applied up to the buckling point. The force σ corresponding to the force can be detected. Alternatively, the user can feel it. Alternatively, the user may feel a clicking sensation when the buckling point is exceeded. Alternatively, a tactile switch can be provided to release the pointer when the user presses it. Releasing the force allows the snap-through buckling structure to return to its original mode.

[0325] In addition, a detection area 241 is provided over the structure that undergoes snap-through buckling, and A display area 231 is provided, and an image to be used for operation is displayed at a position overlapping with the structure that jumps and buckles. For example, a layout suitable for a keyboard can be displayed as a snap-through buckling This can be used for arranging a structure that performs the above. Or, it can be used for a home button. can be used to arrange the structure for snap-through buckling.

[0326] This allows you to push in the image to be used for the displayed operation. As the button is pressed, the user can feel a clicking sensation.

[0327] Or, a member 2 having an area in which a plurality of structures that undergo snap-through buckling are provided over the entire surface. 49 can be used. A detection area 241 is provided so as to overlap the area. A display area 231 is provided on the screen, and an image to be used for operation is displayed on the entire screen. It can be displayed in a position that overlaps with the area.

[0328] This allows the image to be used for operations that give a clicking sensation when pressed automatically. can be freely placed.

[0329] The detector 250 may be disposed on top of the input / output device described in this embodiment. For example, a pressure-sensitive switch can be used for the detection unit 250. Specifically, a conductive material can be used It is used in a dome-shaped structure that undergoes snap buckling, and the dome-shaped structure is used as the contact of a pressure-sensitive switch. This allows the provision of a so-called membrane switch. Alternatively, a switch with a click feeling can be provided. A loop switch can be provided.

[0374] <Configuration example 2 of information processing device> Another configuration of a data processing device of one embodiment of the present invention is shown in FIGS. 13A and 13B. The explanation will be given with reference to the above.

[0375] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 13(A)).

[0376] [First Step] In the first step, the settings are initialized (see FIG. 13(A)(S1)).

[0377] For example, predetermined image information to be displayed at startup and a predetermined mode in which the image information is displayed; and information specifying a predetermined display method for displaying the image information, from the storage unit 212. Specifically, one still image or other moving image information can be used as the predetermined image information. Also, the first mode or the second mode can be used for a predetermined mode.

[0378] [Second step] In the second step, interrupt processing is permitted (see FIG. 13(A)(S2)). The processor that is allowed to process the interrupt can process the interrupt in parallel with the main processing. The processing unit that returns to the main processing from the interrupt processing can This can be reflected in the main processing.

[0379] When the counter value is the initial value, the arithmetic unit is caused to perform an interrupt process. When returning from the program, the counter may be set to a value other than the initial value. After starting up, you can always have the interrupt process run.

[0380] [Third Step] In the third step, the predetermined The image information is displayed using the mode or a predetermined display method (see FIG. 13(A)(S3)). The predetermined mode specifies the mode in which information is displayed, and the predetermined display method specifies the image information. Also, for example, image information VI can be used to display information. Cut.

[0381] For example, one way of displaying the image information VI can be associated with a first mode. Alternatively, other ways of displaying the image information VI can be associated with the second mode. This allows the display method to be selected based on the selected mode.

[0382] First Mode Specifically, a selection signal is applied to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more. The method of providing the display based on the selection signal can be associated with the first mode.

[0383] For example, if a selection signal is supplied at a frequency of 30 Hz or more, preferably 60 Hz or more, a moving image The movement can be displayed smoothly.

[0384] For example, if the image is updated at a frequency of 30 Hz or more, preferably 60 Hz or more, the user's operation The image that changes smoothly in accordance with the user's operation is displayed on the information processing device 200 that the user is operating. It can be shown.

[0385] Second Mode Specifically, the frequency is less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. The method of supplying a selection signal to one scanning line at a time and displaying based on the selection signal is called the second mode. It can be associated with a

[0386] 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 the above, it is possible to display a picture with reduced flicker or flicker. Power consumption can be reduced.

[0387] For example, when the information processing device 200 is used as a clock, the frequency is once per second or once per minute. The display can be updated with frequency, etc.

[0388] Incidentally, when a light-emitting element is used as a display element, the light-emitting element is made to emit light in a pulsed manner. Specifically, the organic EL element emits light in a pulsed manner, and image information can be displayed. The afterglow can be used for display. This may shorten the time for driving the light emitting element and reduce power consumption. In this case, heat generation is suppressed, and therefore deterioration of the light-emitting element can be reduced in some cases.

[0389] [Fourth step] In the fourth step, if a termination command is provided, the process proceeds to the fifth step. If no value is supplied, the process proceeds to the third step (FIG. 13(A)(S4) reference).

[0390] For example, the termination command supplied in the interrupt process may be used for the determination.

[0391] [5th ​​step] In the fifth step, the process ends (see FIG. 13(A)(S5)).

[0392] Interrupt handling The interrupt process comprises the following steps 6 to 8 (see FIG. 13(B)). .

[0393] [Sixth step] In the sixth step, for example, the detection unit 250 is used to detect whether the information processing device 200 is being used. The illuminance of the environment is detected (see FIG. 13(B)(S6)). The color temperature and chromaticity of the ambient light may also be detected.

[0394] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (FIG. 13(B) ) (See S7)). For example, the brightness of the display should not be too dark or too bright. is decided.

[0395] If the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0396] [Eighth Step] In the eighth step, the interrupt process ends (see FIG. 13(B) (S8)).

[0397] <Configuration example 3 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0398] FIG. 14A is a flowchart illustrating a program according to one embodiment of the present invention. (A) is a flowchart illustrating an interrupt process different from the interrupt process shown in FIG. 13(B). It is a chart.

[0399] The information processing device of the third example configuration changes the mode based on a given event. The interrupt process includes a step for performing the above-mentioned operation. This section will explain the differences in detail and explain how to use a similar configuration. The above explanation will be used for the parts that can be described.

[0400] Interrupt handling The interrupt process comprises the following steps 6 to 8 (see FIG. 14(A)). .

[0401] [Sixth step] In the sixth step, if a predetermined event is provided, the process proceeds to the seventh step; If the predetermined event is not provided, proceed to the eighth step (FIG. 14(A) (U6 For example, you can use the condition whether a specific event was provided within a specific period. Specifically, it is possible to perform the above-mentioned operation for 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less. The predetermined period may be a period longer than 0 seconds.

[0402] [Seventh step] In the seventh step, the mode is changed (see FIG. 14(A)(U7)). Specifically, If you have selected the first mode, select the second mode, and then select the second mode. If so, select the first mode.

[0403] For example, the display mode can be changed for a part of the area of ​​the display unit 230. Specifically, the display unit 230 includes the drive circuits GDA, GDB, and GDC. The display mode can be changed for the area to which one drive circuit supplies a selection signal ( See Figure 14(B)).

[0404] For example, the input section 240 in the area overlapping the area where the driver circuit GDB supplies the selection signal is When a specific event is supplied, the driver circuit GDB supplies a selection signal to the display model of the area. The code can be changed (see Figure 14(B) and Figure 14(C)). The driver circuit GDB supplies a "tap" event to the touch panel using The frequency of the selection signal can be changed.

[0405] The signal GCLK is a clock signal that controls the operation of the driver circuit GDB, and the signal PWC Signals PWC1 and PWC2 are pulse width control signals that control the operation of the driver circuit GDB. The circuit GDB outputs a selection signal based on the signal GCLK, the signal PWC1, the signal PWC2, etc. are supplied to the scanning lines G2(m+1) to G2(2m).

[0406] This allows, for example, the driver circuits GDA and GDC to supply a selection signal. Alternatively, the driver circuit GDB can provide the selection signal. The driver circuit GDB selects the area without changing the display of the area to which the driver circuit GDC supplies the selection signal. The display of the area to which the select signal is supplied can be updated. can be suppressed.

[0407] [Eighth Step] In the eighth step, the interrupt process is completed (see FIG. 14(A)(U8)). The interrupt process may be repeatedly executed during the period when the main process is being executed.

[0408] 《Specified Events》 For example, "click" and "drag" operations are performed using a pointing device such as a mouse. Events such as "tap" and "drag" are supplied to the touch panel using a finger as a pointer. Events such as "click" or "swipe" can be used.

[0409] Also, for example, the position of the slide bar pointed by the pointer, the speed of the swipe, the speed of the drag, The degree or the like can be used to provide arguments for the command associated with a given event.

[0410] 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.

[0411] Specifically, a pressure-sensitive detector that comes into contact with a button or the like that is arranged so that it can be pressed into the housing. etc. can be used in the detection unit 250.

[0412] Commands associated with specific events For example, the termination command may be associated with a predetermined event.

[0413] For example, the "page turning" function is used to switch the display from one image information to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed, etc., used when executing are passed using a specified event. can be given.

[0414] 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.

[0415] For example, a command to set a display method or a command to generate image information is generated as a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a specific event. In addition, the argument that determines the brightness of the generated image can be associated with the The determination may be based on the brightness of the environment detected by the 50 .

[0416] For example, information distributed using a push-type service can be acquired using the communication unit 290. An instruction to execute a command can be associated with a given event.

[0417] The qualification to obtain information is determined using the location information detected by the detection unit 250. Specifically, a person who is in a designated classroom, school, conference room, company, building, or other area may This may allow a school or The information processing device 200 can be used as a textbook or the like by receiving teaching materials distributed in classrooms at universities, etc. (See Figure 12(C)). Or, you can receive materials distributed in a conference room of a company, etc. , and can be used for conference materials.

[0442] Note that this embodiment mode can be appropriately combined with other embodiment modes shown in this specification. .

[0443] For example, in this specification, when it is explicitly stated that X and Y are connected, In this case, X and Y are electrically connected, and X and Y are functionally connected. The case where X and Y are directly connected and the case where X and Y are directly connected are both considered to be disclosed in this specification. Therefore, the present invention is not limited to the predetermined connection relationships, for example, the connection relationships shown in the drawings or text. Connections other than those shown in the drawings or text are also considered to be disclosed in the drawings or text. do.

[0444] Here, X and Y are the object (for example, a device, an element, a circuit, a wiring, an electrode, a terminal, a conductive film, a layer, etc.). , etc.).

[0445] An example of a direct connection between X and Y is a circuit that allows electrical connection between X and Y. The elements to be considered (e.g., switches, transistors, capacitance elements, inductors, resistance elements, When no external device (such as a diode, display element, light-emitting element, or load) is connected between X and Y, The elements that allow electrical connection between X and Y (e.g., switches, transistors, capacitors) elements, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.) , X and Y are connected.

[0446] An example of an electrical connection between X and Y is The elements to be considered (e.g., switches, transistors, capacitance elements, inductors, resistance elements, One or more devices (such as diodes, display elements, light-emitting elements, and loads) can be connected between X and Y. It is possible. The switch has a function to control on / off. A switch can be in a conducting state (ON state) or a non-conducting state (OFF state), allowing current to flow. The switch has the function of controlling whether or not the current flows. When X and Y are electrically connected, This includes the case where Y is directly connected.

[0447] An example of a functional connection between X and Y is a function that allows the functional connection between X and Y. Circuits that perform the above functions (for example, logic circuits (inverters, NAND circuits, NOR circuits, etc.), signal conversion conversion circuits (DA conversion circuits, AD conversion circuits, gamma correction circuits, etc.), potential level conversion circuits (voltage power supply circuits (voltage boost circuits, voltage drop circuits, etc.), level shifter circuits that change the signal potential level, etc.) , voltage source, current source, switching circuit, amplifier circuit (which can increase the signal amplitude or current amount, etc.) circuits, operational amplifiers, differential amplifier circuits, source follower circuits, buffer circuits, etc.), signal generation One or more circuits (e.g., memory circuits, control circuits, etc.) can be connected between X and Y. For example, even if another circuit is inserted between X and Y, the signal output from X If X is transmitted to Y, then X and Y are considered to be functionally connected. When X and Y are functionally connected, there is a direct connection between X and Y and a direct connection between X and Y. This also includes the case where the and are electrically connected.

[0448] In addition, if it is explicitly stated that X and Y are electrically connected, are electrically connected (i.e., there is another element or circuit between X and Y) X and Y are functionally connected (i.e., X and Y are functionally connected) and (When there is a functional connection between them via another circuit) and when X and Y are directly connected (i.e., when X and Y are connected without any other element or circuit between them) is considered to be disclosed in the present specification. If it is explicitly stated that it is connected, The same content is considered to be disclosed in the present specification.

[0449] For example, if the source (or first terminal, etc.) of the transistor is connected via Z1 (or (not shown), electrically connected to X, and the drain (or second terminal, etc.) of the transistor is connected to Z 2 (or not), and is electrically connected to Y, or the source of the transistor (or the first terminal, etc.) is directly connected to a part of Z1, and another part of Z1 is directly connected to X. The drain (or 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 is possible to do so.

[0450] For example, "X and Y and the source (or first terminal, etc.) and drain (or second terminal, etc.) of a transistor" The terminals of the transistor (or the first terminal) are electrically connected to each other. 1 terminal, etc.), the drain of the transistor (or the second terminal, etc.), and Y. It can be expressed as "connected to the source (or the first The first terminal of the transistor is electrically connected to X, and the drain of the transistor is electrically connected to the second terminal of the transistor. The transistor source (or first terminal, etc.) is electrically connected to Y, and the transistor source (or first terminal, etc.) is electrically connected to X. The drain (or second terminal, etc.) of the transistor, Y, is electrically connected in this order. " Alternatively, "X is the source (or first terminal, etc.) of the transistor. and the drain (or second terminal, etc.) are electrically connected to Y, and X, the source (or first terminal, etc.) of a transistor, the drain (or second terminal, etc.) of a transistor ), Y is provided in this order of connection. By specifying the order of connections in the circuit configuration using a simple expression method, Distinguish between the source (or first terminal, etc.) and the drain (or second terminal, etc.) of a transistor. The technical scope can be determined by the above.

[0451] Alternatively, for example, "the source (or first terminal, etc.) of a transistor" is electrically connected to X through at least a first connection path, and the first connection path is , and the second connection path is a transistor through a transistor. The source (or first terminal, etc.) of the transistor and the drain (or second terminal, etc.) of the transistor The first connection path is a path via Z1, and the second connection path is a path between the first and second transistors. The drain (or second terminal, etc.) of the capacitor is electrically connected to Y through at least a third connection path. the third connection path does not have the second connection path, and the third connection path The connection path is the path via Z2. The source (or first terminal, etc.) of the resistor is connected to the resistor via Z1 by at least the first connection path. and electrically connected to X, and the first connection path does not have a second connection path; The second connection path has a connection path through a transistor, and (or the second terminal, etc.) is connected to Y via Z2 by at least a third connection path. The third connection path does not have the second connection path. Alternatively, the source (or first terminal, etc.) of the transistor may be at least The first electrical path is electrically connected to X through Z1. The primary path does not have a second electrical path, and the second electrical path is a From the source (or first terminal, etc.) to the drain (or second terminal, etc.) of the transistor The drain (or second terminal, etc.) of the transistor is connected to at least a third The third electrical path is electrically connected to Y through Z2. , does not have a fourth electrical path, and the fourth electrical path is (or second terminal, etc.) to the source (or first terminal, etc.) of the transistor. Using the same expression as these examples, the circuit configuration By defining the connection path in Distinguishing between the first terminal (or the second terminal, etc.) and the drain (or the second terminal, etc.) to determine the technical scope. can be done.

[0452] These representation methods are merely examples, and the present invention is not limited to these representation methods. , Y, Z1, Z2 are objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, layer, etc.).

[0453] In addition, the circuit diagram shows independent components as if they are electrically connected to each other. Even if the components are different, 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 functions as both the wiring and the electrode. Therefore, the electrode in this specification has the functions of both components. The term "electromagnetic connection" 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]
