[0438] 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.

[0439] 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

[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 display a picture with reduced flicker or flicker. Power consumption can be reduced.

[0441] 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.

[0442] 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.

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

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

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

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

[0447] [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. 17B (S6)). The color temperature and chromaticity 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, you should decide whether the display brightness is too dark or too bright. Determine.

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

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

[0451] <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.

[0452] FIG. 18A is a flowchart 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] The information processing device of the third example configuration changes the mode based on a given event. The fact that the interrupt processing includes a step of Here, we will explain the differences in detail and consider whether a similar configuration can be used. The above explanation will be used where possible.

[0454] <<Interrupt Processing>> The interrupt process comprises 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 ( (See Figure 18A (U6)). For example, if a predetermined event is provided within a predetermined period, 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 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 18B).

[0458] 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. (See Figures 18B and 18C.) Specifically, you can change the The driver circuit GDB selects the voltage to be supplied in response to the "tap" event supplied to the touch panel. The frequency of the signals can be changed.

[0459] 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 modulated 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).

[0460] 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.

[0461] [Eighth Step] In the eighth step, the interrupt process is completed (see FIG. 18A (U8)). The interrupt process may be repeatedly executed during the period when the process (2) is being executed.

[0462] 《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.

[0463] 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.

[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 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.

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

[0467] 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.

[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 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 .

[0470] 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.

[0471] 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 16C.) Or, you can receive materials distributed in a company conference room and use them in the meeting. It can be used for meeting materials.

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.

If it is explicitly stated that it is connected, The same content is considered to be disclosed in the present specification.

[0510] 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.

" 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.

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 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.

[0513] 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.).

[0514] 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]
