Specifically, one still image or other moving image information may be used as the predetermined image information. Also, the first mode or the second mode can be used for a given mode.

[0432] [Second step] In the second step, interrupt processing is permitted (see FIG. 17A (S2)). A processor that is enabled to process an interrupt can perform the interrupt process in parallel with the main process. The arithmetic unit that has returned from interrupt processing to the main processing passes the results obtained from the interrupt processing to the main processing. This can be reflected in the processing.

[0433] 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, you can always have the interrupt process.

[0434] [Third step] In a third step, a predetermined The image information is displayed using the mode or a predetermined display method (see FIG. 17A (S3)). The predetermined mode specifies a mode in which information is displayed, and the predetermined display method displays image information. Also, for example, image information VI can be used to display information. .

[0435] For example, one way of displaying the image information VI may be associated with a first mode. Alternatively, other methods 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.

[0436] First mode Specifically, a selection signal is provided to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more. A method of providing a display based on the selection signal can be associated with the first mode.

[0437] For example, when a selection signal is supplied at a frequency of 30 Hz or more, preferably 60 Hz or more, a moving image The movement of the subject can be displayed smoothly.

[0438] For example, if the image is updated at a frequency of 30 Hz or more, and preferably at a frequency of 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.

[0439] Second Mode Specifically, the frequency is 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 scanning line at a time and displaying based on the selection signal is called the second mode. It can be associated with a

[0440] 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 suppress flicker or blinking when displaying. Power consumption can be reduced.

[0441] For example, when the information processing device 200 is used in a clock, the frequency is once per second or once per minute. The display can be updated with frequency, etc.

[0442] By the way, 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 is made to emit light in a pulsed manner, so that image information can be displayed. The afterglow can be used for display. Organic EL elements have excellent frequency characteristics. In this case, the time for driving the light-emitting element can be shortened, and power consumption can be reduced. In this case, heat generation is suppressed, and therefore deterioration of the light-emitting element can be reduced in some cases.

[0443] [Fourth step] In the fourth step, if a termination command is issued (Yes), proceed to the fifth step. If the end command is not provided (No), the process selects to proceed to the third step (Fig. 17A(S4)).

[0444] For example, the end command supplied in the interrupt process may be used for the judgment.

[0445] [5th ​​step] In the fifth step, the process ends (see FIG. 17A (S5)).

[0446] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 17B).

[0447] [Sixth step] In a 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 in which the camera is placed is detected (see FIG. 17B (S6)). Note that the ambient light The color temperature and chromaticity of the light may be detected.

[0448] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (FIG. 17B). For example, it is important to determine whether the display brightness is too dim or too bright. Determine.

[0449] In addition, if the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0450] [8th step] In the eighth step, the interrupt process ends (see FIG. 17B (S8)).

[0451] <Configuration example 3 of information processing device> Another configuration of the data processing device of one embodiment of the present invention will be described with reference to FIG.

[0452] FIG. 18A is a flow chart illustrating a program according to one embodiment of the present invention. 17B is a flowchart illustrating an interrupt process different from the interrupt process shown in FIG. .

[0453] In addition, the third example of the information processing device changes the mode based on a given event. The fact that the interrupt process includes a step of performing the above-mentioned operation is the same as the interrupt process described with reference to FIG. 17B. Here, we will explain the differences in detail and explain how to use a similar configuration. The above explanation will be used where possible.

[0454] <<Interrupt Processing>> The interrupt process includes the following sixth to eighth steps (see FIG. 18A).

[0455] [Sixth step] In the sixth step, if the predetermined event is provided (Yes), the seventh step If the specified event is not provided (No), proceed to step 8 ( For example, the condition may be whether a specific event has been provided within a specific period of time. Specifically, it is preferably 5 seconds or less, 1 second or less, or 0.5 seconds or less. The predetermined period can be 0.1 seconds or less and greater than 0 seconds.

[0456] [Seventh step] In the seventh step, the mode is changed (see FIG. 18A (U7)). If you have selected mode 1, select mode 2, and if you have selected mode 2, In this case, the first mode is selected.

[0457] For example, the display mode of a part of the display unit 230 can be changed. Specifically, the display unit 230 includes the drive circuits GDA, GDB, and GDC. The display mode can be changed for an area to which one drive circuit supplies a selection signal ( See Figure 18B).

[0458] For example, in the input section 240 in the area overlapping the area where the driving circuit GDB supplies the selection signal, When a specific event is supplied, the driver GDB supplies a selection signal to the display model of the area. The user can change the mode (see Fig. 18B and Fig. 18C). The driver circuit GDB selects the voltage that is supplied to the touch panel in response to a "tap" event. The frequency of the signals can be changed.

[0459] The signal GCLK is a clock signal that controls the operation of the driving circuit GDB, and the signal PWC Signals PWC1 and PWC2 are pulse width modulated signals that control the operation of the driver circuit GDB. The circuit GDB outputs a selection signal based on the signals GCLK, PWC1 and PWC2. are supplied to the scanning lines G2(m+1) through G2(2m).

[0460] This allows, for example, the driver circuits GDA and GDC to supply a selection signal. Alternatively, the driver circuit GDA and the driver circuit GDB may 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.

[0461] [8th step] In the eighth step, the interrupt process is ended (see FIG. 18A (U8)). During the period in which the process is being performed, the interrupt process may be repeatedly performed.

[0462] 《Specified Event》 For example, "clicking" and "dragging" provided 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.

[0463] Also, for example, the position of the slide bar pointed to 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.

[0464] 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.

[0465] Specifically, a pressure-sensitive detector that contacts a button or the like that is arranged so that it can be pressed into the housing. etc. can be used for the detection unit 250.

[0466] Commands associated with specific events For example, the termination command may be associated with a certain event.

[0467] For example, a "page turn" function is used to switch the display from one image to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed and other parameters used during execution are sent using a specified event. Can be given.

[0468] 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.

[0469] For example, a command to set a display method or a command to generate image information is generated by a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a given event. In addition, the argument that determines the brightness of the generated image can be associated with the detection unit 2. The determination may be based on the brightness of the environment detected by 50.

[0470] For example, information distributed using a push-type service is acquired using the communication unit 290. An instruction to execute a command or the like can be associated with a given event.

[0471] The qualification to obtain information is determined using the location information detected by the detection unit 250. Specifically, the person may be in a specific classroom, school, conference room, company, building, or other area. This may allow, for example, 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 16C.) Or, you can receive materials distributed in a company's conference room and It can be used in meeting materials.

[0497] In this example, the structure and evaluation results of a manufactured display device according to one embodiment of the present invention are shown in FIG. The explanation will be given with reference to the above.

[0498] FIG. 22 illustrates the display performance of a display device of one embodiment of the present invention.

[0499] <Configuration of the manufactured display device> The display device includes a display panel and a light source.

[0500] Configuration of the display device The specifications of the manufactured display device are shown in Table 1.

[0501] [Table 1]

[0502] <Display results> An image was displayed on the produced display device (see FIG. 22).

[0503] This embodiment can be appropriately combined with other embodiment modes shown in this specification.

[0504] For example, in the present 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 is also considered to be disclosed in the present specification. Therefore, the present invention is not limited to a specific connection relationship, for example, a connection relationship shown in a drawing or a sentence. Any connection relationship other than that shown in the drawings or text is also considered to be disclosed in the drawings or text. do.

[0505] Here, X and Y are objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, layers, etc.). , etc.).

[0506] 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 a resistor (such as an electrode, display element, light-emitting element, or load) is not connected between X and Y, The elements that allow electrical connection between X and Y (e.g., switches, transistors, capacitors, etc.) elements, inductors, resistors, diodes, display elements, light-emitting elements, loads, etc.) , X and Y are connected.

[0507] An example of a case where X and Y are electrically connected is The elements to be considered (e.g., switches, transistors, capacitance elements, inductors, resistance elements, One or more elements (such as an electrode, a display element, a light-emitting element, or a load) can be connected between X and Y. It is possible. The switch has a function that allows it to be turned on and off. A switch can be in a conductive state (on state) or a non-conductive state (off state) and can either pass current or not. The switch has the function of controlling whether or not current flows. When X and Y are electrically connected, This includes the case where Y is directly connected.

[0508] An example of a case where X and Y are functionally connected is a case where a functional connection between X and Y is possible. 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 ( power supply circuits (voltage boost circuits, voltage drop circuits, etc.), level shifter circuits that change the potential level of signals, etc.) , voltage sources, current sources, switching circuits, amplifier circuits (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 devices (such as a memory circuit, a control circuit, 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 are cases where X and Y are directly connected and cases where X and Y are functionally connected. and the case where they are electrically connected to each other.

[0509] 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) When X and Y are functionally connected (i.e., when X and Y are connected), (When there is a functional connection between X and Y via another circuit in between) 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 deemed to be disclosed in the present specification. If it is explicitly stated that it is connected, The same contents are deemed to be disclosed in the present specification and the like.

[0510] For example, the source (or the first terminal, etc.) of the transistor is connected via Z1 (or The drain (or second terminal, etc.) of the transistor is electrically connected to Z 2 (or not), it may be 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.

[0511] 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, etc.) are electrically connected to each other, and X, the source of the transistor (or the first terminal, etc.) 1 terminal, etc.), the drain (or second terminal, etc.) of the transistor, and Y. "The source (or the third) of the transistor is connected to the The drain (or second terminal, etc.) of the transistor is electrically connected to X. 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 a transistor. The transistor is electrically connected to Y via a drain (or a second terminal, etc.) and a transistor is electrically connected to X via a drain (or a second terminal, etc.). The source (or first terminal, etc.) of a resistor, the drain (or second terminal, etc.) of a transistor ), Y is provided in this connection order. By using a simple expression method and specifying the order of connections in the circuit configuration, Distinguish between the source (or first terminal, etc.) and the drain (or second terminal, etc.) of a transistor. The technical scope can be determined based on the above.

[0512] Or, as another way of expressing it, 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 , the second connection path does not have a second connection path, and the second connection path is 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 transistor 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 include the second connection path, and the third connection path The connection path is the path through Z2. The source (or the first terminal, etc.) of the resistor is connected to the resistor via Z1 by at least the first connection path. and X is electrically connected to the first connection path, and the first connection path does not have a second connection path; The second connection path includes a connection path through a transistor, and the second connection path includes a drain of the transistor. (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 the first terminal, etc.) of the transistor may be at least The first electrical path is electrically connected to X through Z1, and the first electrical path is 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. , the fourth electrical path is not included, and the fourth electrical path is a drain of the transistor (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 Distinguish 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.

[0513] Note that these expression methods are merely examples, and the present invention is not limited to these expression methods. , Y, Z1, and Z2 are objects (e.g., devices, elements, circuits, wiring, electrodes, terminals, conductive films, layer, etc.).

[0514] In addition, the circuit diagram shows independent components as if they are electrically connected to each other. Even if the components are the same, one component may have the functions of multiple components. For example, when a part of the wiring also functions as an electrode, one conductive film has the function of the wiring and The electrode functions as both components. The term "electrochemically connected" refers to a case where one conductive film has the functions of multiple components. This also falls within the scope of the above. [Explanation of symbols]
