As a result, interrupt processing can always be performed after the program is started.

[Third step]
In the third step, the image information is displayed using the predetermined mode or the predetermined display method selected in the first step or the interruption process (see FIG. 5A (S3)). The predetermined mode specifies a mode for displaying information, and the predetermined display method specifies a method for displaying image information.

For example, one method for displaying the image information V1 can be associated with the first mode. Alternatively, another method for displaying the image information V1 can be associated with the second mode.

Alternatively, for example, three different methods for displaying the image information V1 can be associated with the first display method to the third display method.

<First mode>
Specifically, a method of supplying a selection signal to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more, and displaying based on the selection signal can be associated with the first mode.

For example, when the selection signal is supplied at a frequency of 30 Hz or higher, preferably 60 Hz or higher, the motion of the moving image can be displayed smoothly.

For example, when an image is updated at a frequency of 30 Hz or higher, preferably 60 Hz or higher, an image that changes so as to smoothly follow the user's operation can be displayed on the information processing apparatus 200 being operated by the user.

<< Second mode >>
Specifically, a method of supplying a selection signal to one scanning line at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than once per minute, and performing display based on the selection signal is described in the second mode. Can be associated with

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, the display can be updated at a frequency of once per second or a frequency of once per minute.

<< First display method >>
Specifically, a method in which the reflective first display element 750 (i, j) is used for display can be used for the first display method. Thereby, for example, power consumption can be reduced. Alternatively, the image information can be favorably displayed with high contrast in a bright environment.

<< Second display method >>
Specifically, a method of using the second display element 550 (i, j) that emits light for display can be used for the second display method. Thereby, for example, image information can be displayed favorably in a dark environment. Alternatively, a photograph or the like can be displayed with good color reproducibility. Alternatively, a fast moving video can be displayed smoothly.

In addition, when displaying the image information V1 using the 2nd display element 550 (i, j), the brightness which displays the image information V1 can be determined based on illumination intensity information. For example, when the illuminance is 5,000 lux or more and less than 100,000 lux, the image information V1 is displayed using the second display element 550 (i, j) so that it is brighter than when the illuminance is less than 5,000 lux.

<< Third display method >>
Specifically, a method in which the first display element 750 (i, j) and the second display element 550 (i, j) are used for display can be used in the third display method. Thereby, power consumption can be reduced. Alternatively, image information can be displayed favorably in a dark environment. Alternatively, a photograph or the like can be displayed with good color reproducibility. Alternatively, a fast moving video can be displayed smoothly.

By the way, a function of adjusting display brightness by using the first display element 750 (i, j) and the second display element 550 (i, j) for display can be referred to as a dimming function. For example, the brightness of a reflective display element can be supplemented by using a display element having a function of emitting light.

In addition, a function of adjusting the display color by using the first display element 750 (i, j) and the second display element 550 (i, j) for display can be referred to as a toning function. For example, the color of the reflective display element can be changed using a display element having a function of emitting light. Specifically, the yellowish hue displayed by the reflective liquid crystal element can be made closer to white using a blue organic EL element. Thereby, for example, the character information can be displayed like characters printed on plain paper. Alternatively, a display that is easy on the eyes can be displayed.

In addition, when the first display element 750 (i, j) and the second display element 550 (i, j) are used for display, the color reflected by the object and the color emitted by the object are multiplied. Thereby, a pictorial display can be performed.

[Fourth step]
In the fourth step, if the end command is supplied, the process proceeds to the fifth step, and if the end command is not supplied, the process proceeds to the third step (see FIGS. 5A and 5S). ).

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 FIG. 5A and S5).

<Interrupt processing>
The interrupt process includes the following sixth to eighth steps (see FIG. 5B). The interrupt process may be repeatedly executed. For example, a method using a timer may be executed every predetermined time. Alternatively, it may be executed when a change in illuminance greater than a predetermined value is observed. Or you may perform based on the instruction | indication of the user of an input / output device.

[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. 5B 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. For example, when the illuminance is equal to or higher than a predetermined value, the first display method is determined, and when the illuminance is lower than the predetermined value, the second display method is determined. Alternatively, when the illuminance is within a predetermined range, the third display method may be determined (see FIGS. 5B and S7).

Specifically, when the illuminance is 100,000 lux or more, the first display method is determined. When the illuminance is less than 5,000 lux, the second display method is determined, and the illuminance is less than 100,000 lux. In the above case, the third display method may be determined.

When the color temperature of ambient light or the chromaticity of ambient light is detected in the sixth step, the display color is adjusted using the second display element 550 (i, j) in the third display method. You may adjust.

For example, when the first display method is used, the control information of the first status is supplied, and when the second display method is used, the control information of the second status is supplied, and the third display method is changed. When used, the control information of the third status is supplied. Thereby, the display unit can change the display method based on the control information.

[Eighth step]
In the eighth step, the interrupt process is terminated (see FIG. 5B (S8)).

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.

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.

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.
