When the selection signal is supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than once per minute, a display in which flicker or flicker is suppressed can be displayed. In addition, power consumption can be reduced.

For example, when the information processing apparatus 200 is used for a clock, the display can be updated at a frequency of once per second or a frequency of once per minute.

By the way, for example, when a light-emitting element is used as a display element, the light-emitting element can emit light in a pulse shape to display image information. Specifically, the organic EL element can emit light in a pulse shape, and the afterglow can be used for display. Since the organic EL element has excellent frequency characteristics, there are cases where the time for driving the light emitting element can be shortened and the power consumption can be reduced. Alternatively, heat generation is suppressed, so that deterioration of the light-emitting element can be reduced in some cases.

[Fourth step]
In the fourth step, if the end command is supplied, the process proceeds to the fifth step. If the end command is not supplied, the process is selected to proceed to the third step (see FIGS. 14A and S4). ).

For example, an end command supplied in the interrupt process may be used for determination.

[Fifth step]
In the fifth step, the process ends (see FIGS. 14A and S5).

<Interrupt processing>
The interrupt process includes the following sixth to eighth steps (see FIG. 14B).

[Sixth Step]
In the sixth step, for example, the detection unit 250 is used to detect the illuminance of the environment in which the information processing apparatus 200 is used (see FIGS. 14B and S6). Note that the color temperature or chromaticity of the ambient light may be detected instead of the illuminance of the environment.

[Seventh Step]
In the seventh step, a display method is determined based on the detected illuminance information (see FIGS. 14B and S7). For example, the display brightness is determined not to be too dark or too bright.

When the color temperature of ambient light or the chromaticity of ambient light is detected in the sixth step, the display color may be adjusted.

[Eighth step]
In the eighth step, the interrupt process is terminated (see FIGS. 14B and S8).

<Configuration example 2 of information processing apparatus>>
Another structure of the information processing device of one embodiment of the present invention is described with reference to FIG.

FIG. 15A is a flowchart illustrating a program of one embodiment of the present invention. FIG. 15A is a flowchart for explaining interrupt processing different from the interrupt processing shown in FIG.

The configuration example 3 of the information processing device is different from the interrupt processing described with reference to FIG. 14B in that the interrupt processing includes a step of changing the mode based on the supplied predetermined event. . Here, different portions will be described in detail, and the above description will be applied to portions that can use the same configuration.

<Interrupt processing>
The interrupt process includes the following sixth to eighth steps (see FIG. 15A).

[Sixth Step]
In the sixth step, if a predetermined event is supplied, the process proceeds to the seventh step. If a predetermined event is not supplied, the process proceeds to the eighth step (see FIGS. 15A and U6). ). For example, it can be used as a condition whether or not a predetermined event is supplied during a predetermined period. Specifically, the predetermined period can be a period of 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less and longer than 0 seconds.

[Seventh Step]
In the seventh step, the mode is changed (see FIGS. 15A and U7). Specifically, when the first mode is selected, the second mode is selected, and when the second mode is selected, the first mode is selected.

For example, the display mode can be changed for some areas of the display unit 230. Specifically, the display mode can be changed for a region where one driver circuit of the display portion 230 including the driver circuit GDA, the driver circuit GDB, and the driver circuit GDC supplies a selection signal (see FIG. 15B). ).

For example, when a predetermined event is supplied to the input unit 240 in an area overlapping with an area where the drive circuit GDB supplies a selection signal, the display mode of the area where the drive circuit GDB supplies the selection signal may be changed. (See FIGS. 15B and 15C). Specifically, the frequency of the selection signal supplied by the drive circuit GDB can be changed according to a “tap” event supplied to the touch panel using a finger or the like.

Signal GCLK is a clock signal for controlling the operation of drive circuit GDB, and signal PWC1 and signal PWC2 are pulse width control signals for controlling the operation of drive circuit GDB. The drive circuit GDB supplies a selection signal to the scanning lines G2 (m + 1) to G2 (2m) based on the signal GCLK, the signal PWC1, the signal PWC2, and the like.

Thereby, for example, the drive circuit GDB and the drive circuit GDC can supply the selection signal without supplying the selection signal. Alternatively, the display of the region where the drive circuit GDB supplies the selection signal can be updated without changing the display of the region where the drive circuit GDA and the drive circuit GDC supply the selection signal. Alternatively, power consumed by the driver circuit can be suppressed.

[Eighth step]
In the eighth step, the interrupt process is terminated (see FIGS. 15A and U8). Note that interrupt processing may be repeatedly executed during a period in which main processing is being executed.

《Predetermined event》
For example, an event such as “click” or “drag” supplied using a pointing device such as a mouse, an event such as “tap”, “drag” or “swipe” supplied to a touch panel using a finger or the like as a pointer Can be used.

Further, for example, an argument of a command associated with a predetermined event can be given using the position of the slide bar pointed to by the pointer, the swipe speed, the drag speed, or the like.

For example, the information detected by the detection unit 250 can be compared with a preset threshold value, and the comparison result can be used as an event.

Specifically, a pressure-sensitive detector or the like that contacts a button or the like that can be pushed into the housing can be used for the detection unit 250.

《Instructions related to predetermined events》
For example, an end instruction can be associated with a particular event.

For example, a “page turning command” for switching display from one displayed image information to another image information can be associated with a predetermined event. Note that an argument that determines a page turning speed used when executing the “page turning instruction” can be given using a predetermined event.

For example, a “scroll command” for moving the display position of a part of one image information displayed to display another part continuous to the part can be associated with a predetermined event. It should be noted that an argument for determining the speed of moving the display used when executing the “scroll command” can be given using a predetermined event.

For example, a command for setting a display method or a command for generating image information can be associated with a predetermined event. An argument that determines the brightness of the image to be generated can be associated with a predetermined event. Further, an argument for determining the brightness of the image to be generated may be determined based on the brightness of the environment detected by the detection unit 250.

For example, a command for acquiring information distributed using a push-type service using the communication unit 290 can be associated with a predetermined event.

In addition, you may determine the presence or absence of the qualification to acquire information using the positional information which the detection part 250 detects. Specifically, it may be determined that the person is qualified to acquire information when in or in a predetermined classroom, school, conference room, company, building, or the like. Thus, for example, the teaching material distributed in a classroom such as a school or university can be received, and the information processing apparatus 200 can be used as a textbook (see FIG. 13C). Alternatively, a material distributed in a conference room of a company or the like can be received and used as a conference material.

Note that this embodiment can be combined with any of the other embodiments described in this specification as appropriate.

Note that this embodiment can be combined with any of the other embodiments described in this specification as appropriate.

For example, in this specification and the like, when X and Y are explicitly described as being connected, X and Y are electrically connected, and X and Y are functional. And the case where X and Y are directly connected are disclosed in this specification and the like. Therefore, it is not limited to a predetermined connection relationship, for example, the connection relationship shown in the figure or text, and anything other than the connection relation shown in the figure or text is also described in the figure or text.

Here, X and Y are assumed to be objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, etc.).

As an example of the case where X and Y are directly connected, an element that enables electrical connection between X and Y (for example, a switch, a transistor, a capacitor, an inductor, a resistor, a diode, a display, etc.) Element, light emitting element, load, etc.) are not connected between X and Y, and elements (for example, switches, transistors, capacitive elements, inductors) that enable electrical connection between X and Y X and Y are not connected via a resistor element, a diode, a display element, a light emitting element, a load, or the like.

As an example of the case where X and Y are electrically connected, an element (for example, a switch, a transistor, a capacitive element, an inductor, a resistance element, a diode, a display, etc.) that enables electrical connection between X and Y is shown. More than one element, light emitting element, load, etc.) can be connected between X and Y. Note that the switch has a function of controlling on / off. That is, the switch is in a conductive state (on state) or a non-conductive state (off state), and has a function of controlling whether or not to pass a current. Alternatively, the switch has a function of selecting and switching a path through which a current flows. Note that the case where X and Y are electrically connected includes the case where X and Y are directly connected.

As an example of the case where X and Y are functionally connected, a circuit (for example, a logic circuit (an inverter, a NAND circuit, a NOR circuit, etc.) that enables a functional connection between X and Y, signal conversion, etc. Circuit (DA conversion circuit, AD conversion circuit, gamma correction circuit, etc.), potential level conversion circuit (power supply circuit (boost circuit, step-down circuit, etc.), level shifter circuit that changes signal potential level, etc.), voltage source, current source, switching Circuit, amplifier circuit (circuit that can increase signal amplitude or current amount, operational amplifier, differential amplifier circuit, source follower circuit, buffer circuit, etc.), signal generation circuit, memory circuit, control circuit, etc.) One or more can be connected between them. As an example, even if another circuit is interposed between X and Y, if the signal output from X is transmitted to Y, X and Y are functionally connected. To do. Note that the case where X and Y are functionally connected includes the case where X and Y are directly connected and the case where X and Y are electrically connected.

In addition, when it is explicitly described that X and Y are electrically connected, a case where X and Y are electrically connected (that is, there is a separate connection between X and Y). And X and Y are functionally connected (that is, they are functionally connected with another circuit between X and Y). And the case where X and Y are directly connected (that is, the case where another element or another circuit is not connected between X and Y). It shall be disclosed in the document. In other words, when it is explicitly described that it is electrically connected, the same contents as when it is explicitly described only that it is connected are disclosed in this specification and the like. It is assumed that

Note that for example, the source (or the first terminal) of the transistor is electrically connected to X through (or not through) Z1, and the drain (or the second terminal or the like) of the transistor is connected to Z2. Through (or without), Y is electrically connected, or the source (or the first terminal, etc.) of the transistor is directly connected to a part of Z1, and another part of Z1 Is directly connected to X, and 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. Then, it can be expressed as follows.

For example, “X and Y, and the source (or the first terminal or the like) and the drain (or the second terminal or the like) of the transistor are electrically connected to each other. The drain of the transistor (or the second terminal, etc.) and the Y are electrically connected in this order. ” Or “the source (or the first terminal or the like) of the transistor is electrically connected to X, the drain (or the second terminal or the like) of the transistor is electrically connected to Y, and X or the source ( Or the first terminal or the like, the drain of the transistor (or the second terminal, or the like) and Y are electrically connected in this order. Or “X is electrically connected to Y through the source (or the first terminal) and the drain (or the second terminal) of the transistor, and X is the source of the transistor (or the first terminal). Terminal, etc.), the drain of the transistor (or the second terminal, etc.), and Y are provided in this connection order. By using the same expression method as in these examples and defining the order of connection in the circuit configuration, the source (or the first terminal, etc.) and the drain (or the second terminal, etc.) of the transistor are separated. Apart from that, the technical scope can be determined.

Alternatively, as another expression method, for example, “a source (or a first terminal or the like 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 includes a transistor source (or first terminal or the like) and a transistor drain (or second terminal or the like) through the transistor. The first connection path is a path through Z1, and the drain (or the second terminal, etc.) of the transistor is electrically connected to Y through at least the third connection path. The third connection path is connected and does not have the second connection path, and the third connection path is a path through Z2. " Or, “the source (or the first terminal or the like) of the transistor is electrically connected to X via Z1 by at least a first connection path, and the first connection path is a second connection path. The second connection path has a connection path through the transistor, and the drain (or the second terminal, etc.) of the transistor is at least connected to Z2 by the third connection path. , Y, and the third connection path does not have the second connection path. Or “the source of the transistor (or the first terminal or the like) is electrically connected to X through Z1 by at least a first electrical path, and the first electrical path is a second electrical path Does not have an electrical path, and the second electrical path is an electrical path from the source (or first terminal or the like) of the transistor to the drain (or second terminal or the like) of the transistor; The drain (or the second terminal or the like) of the transistor is electrically connected to Y through Z2 by at least a third electrical path, and the third electrical path is a fourth electrical path. The fourth electrical path is an electrical path from the drain (or second terminal or the like) of the transistor to the source (or first terminal or the like) of the transistor. can do. Using the same expression method as those examples, by defining the connection path in the circuit configuration, the source (or the first terminal or the like) of the transistor and the drain (or the second terminal or the like) are distinguished. The technical scope can be determined.

In addition, these expression methods are examples, and are not limited to these expression methods. Here, it is assumed that X, Y, Z1, and Z2 are objects (for example, devices, elements, circuits, wirings, electrodes, terminals, conductive films, layers, and the like).

In addition, even when the components shown in the circuit diagram are electrically connected to each other, even when one component has the functions of a plurality of components. There is also. For example, in the case where a part of the wiring also functions as an electrode, one conductive film has both the functions of the constituent elements of the wiring function and the electrode function. Therefore, the term “electrically connected” in this specification includes in its category such a case where one conductive film has functions of a plurality of components.

The residue accompanying the etching process observed in the opening of the colored film 521R containing the red material was less than that of the colored film containing other color materials. Further, the shape of the opening of the colored film 521R containing a red material was good. Note that the green material and the blue material contain copper, and the red material does not contain copper.
