Note that the same structure as the transistor M can be used for the transistor MD.

<Transistor>
For example, a semiconductor film that can be formed in the same process can be used for a transistor in a driver circuit and a pixel circuit.

For example, a bottom-gate transistor, a top-gate transistor, or the like can be used as a driver circuit transistor or a pixel circuit transistor.

By the way, for example, a bottom-gate transistor production line using amorphous silicon as a semiconductor can be easily modified to a bottom-gate transistor production line using an oxide semiconductor as a semiconductor. For example, a top gate type production line using polysilicon as a semiconductor can be easily modified to a top gate type transistor production line using an oxide semiconductor as a semiconductor. Both modifications can make effective use of existing production lines.

For example, a transistor in which a semiconductor containing a Group 14 element is used for a semiconductor film can be used. Specifically, a semiconductor containing silicon can be used for the semiconductor film. For example, a transistor in which single crystal silicon, polysilicon, microcrystalline silicon, amorphous silicon, or the like is used for a semiconductor film can be used.

Note that the temperature required for manufacturing a transistor using polysilicon as a semiconductor is lower than that of a transistor using single crystal silicon as a semiconductor.

In addition, the field effect mobility of a transistor using polysilicon as a semiconductor is higher than that of a transistor using amorphous silicon as a semiconductor. Thereby, the aperture ratio of the pixel can be improved. In addition, a pixel provided with extremely high definition, a gate driver circuit, and a source driver circuit can be formed over the same substrate. As a result, the number of parts constituting the electronic device can be reduced.

The reliability of a transistor using polysilicon as a semiconductor is superior to a transistor using amorphous silicon as a semiconductor.

In addition, a transistor using a compound semiconductor can be used. Specifically, a semiconductor containing gallium arsenide can be used for the semiconductor film.

In addition, a transistor using an organic semiconductor can be used. Specifically, an organic semiconductor containing polyacenes or graphene can be used for the semiconductor film.

For example, a transistor in which an oxide semiconductor is used for a semiconductor film can be used. Specifically, an oxide semiconductor containing indium or an oxide semiconductor containing indium, gallium, and zinc can be used for the semiconductor film.

As an example, a transistor whose leakage current in an off state is smaller than that of a transistor using amorphous silicon as a semiconductor film can be used. Specifically, a transistor in which an oxide semiconductor is used for a semiconductor film can be used.

Accordingly, as compared with a pixel circuit using a transistor using amorphous silicon as a semiconductor film, the time during which the pixel circuit can hold an image signal can be lengthened. Specifically, the selection signal can be supplied at a frequency of less than 30 Hz, preferably less than 1 Hz, more preferably less than once per minute while suppressing the occurrence of flicker. As a result, fatigue accumulated in the user of the information processing apparatus can be reduced. In addition, power consumption associated with driving can be reduced.

For example, a transistor including the semiconductor film 508, the conductive film 504, the conductive film 512A, and the conductive film 512B can be used for the switch SW1 (see FIG. 7B). Note that the insulating film 506 includes a region sandwiched between the semiconductor film 508 and the conductive film 504.

The conductive film 504 includes a region overlapping with the semiconductor film 508. The conductive film 504 has a function of a gate electrode. The insulating film 506 has a function of a gate insulating film.

The conductive films 512A and 512B are electrically connected to the semiconductor film 508. The conductive film 512A has one of the function of the source electrode and the function of the drain electrode, and the conductive film 512B has the other of the function of the source electrode and the function of the drain electrode.

In addition, a transistor including the conductive film 524 can be used for a transistor in a driver circuit or a pixel circuit (see FIG. 6B). The conductive film 524 includes a region in which the semiconductor film 508 is sandwiched between the conductive film 504 and the conductive film 504. Note that the insulating film 516 includes a region sandwiched between the conductive film 524 and the semiconductor film 508. For example, the conductive film 524 can be electrically connected to a wiring that supplies the same potential as the conductive film 504.

For example, a conductive film in which a 10-nm-thick film containing tantalum and nitrogen and a 300-nm-thick film containing copper are stacked can be used for the conductive film 504. Note that the film containing copper includes a region between which the film containing tantalum and nitrogen is sandwiched between the film containing copper.

For example, a stacked film in which a 400-nm-thick film containing silicon and nitrogen and a 200-nm-thick film containing silicon, oxygen, and nitrogen are stacked can be used for the insulating film 506. Note that the film containing silicon and nitrogen includes a region between the semiconductor film 508 and the film containing silicon, oxygen, and nitrogen.

For example, a 25-nm-thick film containing indium, gallium, and zinc can be used for the semiconductor film 508.

For example, a conductive film in which a 50-nm-thick film containing tungsten, a 400-nm-thick film containing aluminum, and a 100-nm-thick film containing titanium are stacked in this order as the conductive film 512A or the conductive film 512B. Can be used. Note that the film containing tungsten includes a region in contact with the semiconductor film 508.

The communication unit 290 has a function of supplying information to the network and acquiring information from the network.

"program"
The program of one embodiment of the present invention includes the following steps (see FIG. 24A).

[First step]
In the first step, settings are initialized (see FIGS. 24A and S1).

For example, predetermined image information to be displayed at startup, a predetermined mode for displaying the image information, and information for specifying a predetermined display method for displaying the image information are acquired from the storage unit 212. Specifically, one still image information or other moving image information can be used as predetermined image information. Further, the first mode or the second mode can be used as a predetermined mode. Further, the first display method, the second display method, or the third display method can be used as a predetermined display method.

[Second step]
In the second step, interrupt processing is permitted (see FIGS. 24A and S2). Note that an arithmetic unit that is permitted to perform interrupt processing can perform interrupt processing in parallel with main processing. The arithmetic unit that has returned to the main process from the interrupt process can reflect the result obtained by the interrupt process to the main process.

Note that when the counter value is an initial value, the arithmetic unit performs interrupt processing, and when returning from the interrupt processing, the counter may be set to a value other than the initial value. 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 FIGS. 24A and S3). The predetermined mode specifies a mode for displaying information, and the predetermined display method specifies a method for displaying image information. Further, for example, the image information V1, the information V11, or the information V12 can be used as information to be displayed.

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. Thereby, a display method can be selected based on the selected mode.

For example, three different methods for displaying the image information V1 can be associated with the first display method to the third display method. Thereby, it is possible to display based on the selected 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, 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 for the second 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.

<< First display method >>
Specifically, a method using the first display element 750 (i, j) 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 using the second display element 550 (i, j) for display can be used for the second display method. Thereby, for example, an image can be favorably displayed 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, an image can be favorably displayed 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. Or the display which a user feels comfortable can be performed.

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, an image can be displayed with expression like a picture.

Note that the brightness of the image information V1 displayed using the second display element 550 (i, j), which is displayed by being superimposed on the image information V1 displayed using the first display element 750 (i, j), is set. It can be determined according to illuminance information and user preference. Thereby, the display which a user feels comfortable 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. 24A 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. 24A and S5).

<Interrupt processing>
The interrupt process includes the following sixth to eighth steps (see FIG. 24B).

[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. 24B 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 in a predetermined range, the third display method may be determined (see FIGS. 24B 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.

Further, for example, when the first display method is used, the first status control information SS is supplied, and when the second display method is used, the second status control information SS is supplied, and the third status control information SS is supplied. When the display method is used, the control information SS of the third status is supplied.

[Eighth step]
In the eighth step, the interrupt process is terminated (see FIGS. 24B 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. 25 is a flowchart illustrating a program of one embodiment of the present invention. FIG. 25 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. 24B 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. 25).

[Sixth Step]
In the sixth step, when a predetermined event is supplied, the process proceeds to a seventh step, and when the predetermined event is not supplied, the process proceeds to an eighth step (see FIG. 25 (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 FIG. 25 (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.

[Eighth step]
In the eighth step, the interrupt process is terminated (see FIG. 25 (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.

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.
