[0073] (Embodiment 1) In this embodiment, a structure of a display panel according to one embodiment of the present invention will be described with reference to FIGS. While explaining.

[0076] 3A and 3B illustrate a structure of a display panel according to one embodiment of the present invention. 3(B) is a top view of a display panel according to an embodiment, and FIG. 3(B) is a part of FIG. 3(A).

[0077] 4A and 4B illustrate a structure of a display panel according to one embodiment of the present invention. 4 is a cross-sectional view taken along the lines X1-X2, X3-X4, and X9-X10 of FIG. 1B is a circuit diagram illustrating the configuration of pixel circuit 530(i,j).

[0078] 5A and 5B illustrate a structure of a display panel according to one embodiment of the present invention. 5(A) is a cross-sectional view of the pixel 702(i,j), and FIG. 5(B) is a cross-sectional view illustrating a part of FIG. 5(A). Figure.

[0079] In this specification, variables that take integer values of 1 or more may be used as symbols. For example, (p) includes a variable p that takes an integer value of 1 or more, and identifies any of the components up to p. 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.

[0080] <Configuration Example 1 of Display Panel 700> The display panel 700 described in this embodiment includes a display area 231 and a functional layer 520. (See FIG. 3(A) and FIG. 4(A)). The display area 231 includes pixels 702(i, j). (See Figure 3(B)).

[0081] <<Configuration example 1 of pixel 702(i,j)>> Pixel 702(i,j) includes a display element 550(i,j), a color conversion layer CC(j), and an absorption layer CF(j) (see Figure 1(A) and Figure 1(B)).

[0082] Configuration Example 1 of Display Element 550(i,j) The display element 550(i,j) emits light h1. For example, blue light or ultraviolet light is used as light h1. In addition, a light emitting element that emits light h1 can be used as the display element 550(i, j). Specifically, an organic EL element or the like can be used as the display element 550(i, j). It is possible.

[0083] For example, a tandem-type light-emitting element having a configuration including a plurality of light-emitting units and an intermediate layer may be used as a display element. Specifically, a light emitting element containing a material that emits blue light can be used. A configuration including two or more light-emitting units each containing a light unit and a material that also emits blue light. can be used for the display element 550(i,j). By stacking the units with an intermediate layer in between, the amount of light emitted can be increased without increasing the current density. This makes it possible to improve the reliability of the display panel.

[0084] <<Configuration example 1 of absorbing layer CF(j)>> The absorption layer CF(j) overlaps the display element 550(i,j), and the absorption layer CF(j) absorbs the light h1. (See Figure 1(A), Figure 1(C) or Figure 2(A)).

[0085] For example, a material that absorbs light h1 can be used for the absorption layer CF(j). A material that absorbs light h1 or ultraviolet light can be used for the absorption layer CF(j). For example, , a sharp cut filter that transmits yellow light can be used for the absorption layer CF(j). (See Figure 1(C)). Alternatively, a bandpass filter that transmits green light can be placed on the absorption layer CF(j ) (see FIG. 2(A)). As a result, the absorption layer CF(j) can be used as a display element. 550(i,j) can absorb the light h1 emitted by the object. Alternatively, when light h1 contained in external light reaches the color conversion layer CC(j), it can be absorbed. You can reduce the intensity before it gets there.

[0086] <<Configuration example 1 of color conversion layer CC(j)>> Color conversion layer CC(j) is sandwiched between absorption layer CF(j) and display element 550(i,j). Furthermore, the color conversion layer CC(j) converts the light h1 into light h2.

[0087] For example, a phosphor can be used in the color conversion layer CC(j). It can be used for the color conversion layer CC(j).

[0088] The light h2 has a spectrum that contains a higher proportion of light with longer wavelengths than the light h1 (FIG. 1 (See (C)). For example, blue light can be used as light h1 and green light can be used as light h2. Specifically, quantum dots that convert blue light h1 into green light h2 are placed in the color conversion layer CC(j ) This allows light h1 to be efficiently converted into light h2. Alternatively, light h1 can be converted into light h2 with a narrow spectral half-width. It can display vivid colors.

[0089] This allows the light h1 emitted by the display element 550(i, j) to be converted into light h2. Alternatively, the light h1 contained in the external light can be weakened before it reaches the color conversion layer CC(j). Alternatively, it is possible to suppress the phenomenon in which light h1 contained in external light is converted into light h2. It is also possible to prevent the black display from being damaged by external light. Or it can be displayed with high contrast, resulting in less convenience or reliability. An excellent novel display panel can be provided.

[0090] <<Configuration example 2 of absorbing layer CF(j)>> Furthermore, for example, the absorption layer CF(j) absorbs light h1 and light h3. Note that light h3 is Compared to light h2, it has a spectrum that contains a higher proportion of light with longer wavelengths (Fig. 1(A) and See Figure 2(A)).

[0091] Specifically, green light h2 is used, and a color filter that transmits green light h2 is provided as the absorption layer C. For example, a bandpass filter that transmits green light can be used for F(j). This can be used for the absorption layer CF(j) (see FIG. 2(A)). can, for example, absorb blue light h1 and red light h3.

[0092] This allows the light h1 and light h3 contained in the external light to be absorbed. This can prevent the display from being damaged by external light. As a result, a novel display panel with excellent convenience and reliability can be provided. We can provide you with a guide.

[0093] <<Configuration example 2 of color conversion layer CC(j)>> Also, for example, the color conversion layer CC(j) converts light h1 into light h2 and light h3 (FIG. 1( B) and Figure 2(A)).

[0094] Specifically, blue light h1 is converted into green light h2 and red light h3 using a phosphor. For example, quantum dots that convert blue light h1 into green light h2 and blue The color conversion layer CC(j) is made by mixing quantum dots that convert red light h1 into red light h3. This can be done.

[0095] This converts the light h1 emitted by the display element 550(i,j) into light h2 and light h3. Or, the converted light h3 can be absorbed. Or, the converted light h3 can be absorbed. This can prevent the phenomenon in which the light h1 that is received is converted into light h2 and light h3. Or, it can suppress the phenomenon where the vivid display using light h2 is impaired by light h3. As a result, a novel display panel that is highly convenient and reliable can be provided. can.

[0096] <Configuration Example 2 of Display Panel 700> In addition, in the display panel described in this embodiment, the display area 231 is a pixel 702(i, j+1 ) (see FIG. 3(B)).

[0097] <<Configuration example of pixel 702(i, j+1)>> The pixel 702(i, j+1) is a display element 550(i, j+1), a color conversion layer CC(j+1), and an absorption layer CF(j+1) (see FIGS. 1(A) and 1(B)).

[0098] <<Configuration example of display element 550(i, j+1)>> The display element 550(i, j+1) emits light h1. For example, blue light or ultraviolet light The light emitting element that emits the light h1 is used as the display element 550(i, j+1). Specifically, an organic EL element or the like can be used as the display element 550(i, j+1). For example, the same configuration as that used for the display element 550(i, j) can be used for the display element 550(i, j). It can be used for (i,j+1).

[0367] <Configuration Example 2 of the Calculation Device 210> The arithmetic unit 210 includes an artificial intelligence unit 213 (see FIG. 10(A)). , and generates control information CI based on input information II or sensed information DS.

[0368] [Natural Language Processing for Input Information II] Specifically, the artificial intelligence unit 213 performs natural language processing on the input information II and extracts the following from the entire input information II: For example, the artificial intelligence unit 213 can extract one feature from the input information II.

[0375] <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. 11A and 11B. The explanation will be given with reference to the above.

[0376] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 11(A)).

[0377] [First Step] In the first step, the settings are initialized (see FIG. 11(A)(S1)).

[0378] 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.

[0379] [Second step] In the second step, interrupt processing is permitted (see FIG. 11(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.

[0380] 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.

[0381] [Third Step] In the third step, the predetermined The image information is displayed using the mode or a predetermined display method (see FIG. 11(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 V1 can be used as information to be displayed. Cut.

[0382] For example, one way of displaying image information V1 can be associated with a first mode. Alternatively, other ways of displaying the image information V1 can be associated with the second mode. This allows the display method to be selected based on the selected mode.

[0383] 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.

[0384] 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.

[0385] 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.

[0386] 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

[0387] 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.

[0388] 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.

[0389] 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.

[0390] [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. 11(A)(S4) reference).

[0391] For example, the termination command supplied in the interrupt process may be used for the determination.

[0392] [5th step] In the fifth step, the process ends (see FIG. 11(A)(S5)).

[0393] Interrupt handling The interrupt process comprises the following steps 6 to 8 (see FIG. 11(B)). .

[0394] [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. 11(B)(S6)). The color temperature and chromaticity of the ambient light may also be detected.

[0395] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (FIG. 11(B) ) (See S7)). For example, the brightness of the display should not be too dark or too bright. is decided.

[0396] If the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0397] [Eighth Step] In the eighth step, the interrupt process ends (see FIG. 11(B) (S8)).

[0398] <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.

[0399] FIG. 12A 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. 11(B). It is a chart.

[0400] 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.

[0401] <<Interrupt Processing>> The interrupt process comprises the following steps 6 to 8 (see FIG. 12(A)). .

[0402] [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. 12(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.

[0403] [Seventh step] In the seventh step, the mode is changed (see FIG. 12(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.

[0404] 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 12(B)).

[0405] 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 12(B) and Figure 12(C)). The driver circuit GDB supplies a "tap" event to the touch panel using The frequency of the selection signal can be changed.

[0406] 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 G21(m+1) to G21(2m).

[0407] This allows, for example, the driver circuits GDA and GDC to supply a selection signal. Alternatively, the driver circuit GDB can supply 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.

[0408] [Eighth Step] In the eighth step, the interrupt process is completed (see FIG. 12(A)(U8)). The interrupt process may be repeatedly executed during the period when the main process is being executed.

[0409] 《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.

[0410] 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.

[0411] 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.

[0412] 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.

[0413] Commands associated with specific events For example, the termination command may be associated with a predetermined event.

[0414] 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.

[0415] 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.

[0416] 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 .

[0417] 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.

[0418] 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 10(C)). Or, you can receive materials distributed in a conference room of a company, etc. , and can be used for conference materials.

[0419] Note that this embodiment mode can be appropriately combined with other embodiment modes shown in this specification. .

[0450] 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.).

[0451] 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]
