In addition, 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 of a driving circuit and a pixel circuit.

For example, a transistor for a driving circuit or a transistor for a pixel circuit may be used, such as a bottom-gate transistor or a top-gate transistor.

Here, for example, a production line of a bottom-gate transistor including an amorphous silicon as a semiconductor can be easily converted into a production line of a bottom-gate transistor including an oxide semiconductor as a semiconductor. In addition, for example, a production line of a top-gate transistor including a polycrystalline silicon as a semiconductor can be easily converted to a production line of a top-gate transistor including a semiconductor including an oxide semiconductor. Either of these transformations can make effective use of conventional production lines.

For example, a transistor using a semiconductor containing a Group 14 element for a semiconductor film can be used. Specifically, a semiconductor including silicon can be used for the semiconductor film. For example, a transistor using single crystal silicon, polycrystalline silicon, microcrystalline silicon, or amorphous silicon for a semiconductor film can be used.

In addition, a field effect mobility of a transistor using polycrystalline silicon for a semiconductor is higher than a field effect mobility of a transistor using amorphous silicon for a semiconductor. Thereby, the aperture ratio of a pixel can be improved. In addition, the pixels provided at an extremely high density can be formed on the same substrate as the gate driving circuit and the source driving circuit. As a result, the number of components constituting the electronic device can be reduced.

A transistor using polycrystalline silicon for semiconductors is more reliable than a transistor using amorphous silicon for semiconductors.

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 polyacene or graphene can be used for the semiconductor film.

For example, an transistor using an oxide semiconductor 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.

For example, a transistor having a smaller leakage current in the off state than a transistor using amorphous silicon for a semiconductor film may be used. Specifically, a transistor using an oxide semiconductor for a semiconductor film can be used.

Therefore, compared with a pixel circuit using an transistor using amorphous silicon for a semiconductor film, the time during which the pixel circuit can hold an image signal can be extended. Specifically, the occurrence of flicker can be suppressed and supplied at a frequency lower than 30 Hz, preferably lower than 1 Hz, and more preferably lower than 1 time / minute. Select the signal. As a result, eyestrain of the user of the data processing device can be reduced. In addition, power consumption for 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 as the switch SW1 (see FIG. 12B). In addition, 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 the semiconductor film 508. The conductive film 504 has a function of a gate electrode. The insulating film 506 functions as a gate insulating film.

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

The transistor including the conductive film 524 may be used as a transistor of a driving circuit or a pixel circuit (see FIG. 11B). The conductive film 524 includes a region in which the semiconductor film 508 is sandwiched between the conductive film 524 and the conductive film 504. In addition, the insulating film 516 includes a region sandwiched between the conductive film 524 and the semiconductor film 508. In addition, for example, a wiring that supplies the same potential as the conductive film 504 may be electrically connected to the conductive film 524.

For example, a conductive film including a film having a thickness of 10 nm including tantalum and nitrogen and a film having a thickness of 300 nm including copper can be used as the conductive film 504. The copper-containing film includes a region in which a film containing tantalum and nitrogen is sandwiched between the copper-containing film and the insulating film 506.

For example, the thickness including silicon and nitrogen can be stacked to A material of a 400 nm film and a 200 nm-thick film including silicon, oxygen, and nitrogen is used for the insulating film 506. The film containing silicon and nitrogen includes a region in which a film containing silicon, oxygen, and nitrogen is sandwiched between the film and silicon film 508.

For example, a film having a thickness of 25 nm including indium, gallium, and zinc can be used as the semiconductor film 508.

For example, a conductive film in which a 50-nm-thick film including tungsten, a 400-nm-thick film including aluminum, and a 100-nm-thick film including titanium can be sequentially stacked as the conductive film 512A or the conductive film 512B.

Here, for example, when a light-emitting element is used as the second display element, the light-emitting element can be caused to emit light in a pulse shape to display image data. Specifically, it is possible to cause the organic EL element to emit light in a pulse shape and perform display using afterglow. Since the organic EL element has excellent frequency characteristics, the driving time of the light emitting element may be shortened and power consumption may be reduced. Alternatively, since the heat generation of the light emitting element is suppressed, deterioration of the light emitting element may be reduced in some cases.

〈〈 First display method 〉〉

Specifically, as the first display method, a method of displaying using the first display element 750 (i, j) can be used. Thereby, for example, power consumption can be reduced. Alternatively, the image data can be displayed well with high contrast in a bright environment.

〈〈 Second Display Method 〉〉

Specifically, as the second display method, a method of displaying using the second display element 550 (i, j) can be used. Thereby, for example, an image can be displayed well in a dim environment. Alternatively, photos and the like can be displayed with good color reproducibility. Alternatively, fast-moving motion pictures can be displayed smoothly.

When the second display element 550 (i, j) is used to display the image data V1, the brightness when the image data V1 is displayed can be determined according to the illuminance data. For example, at illuminances above 5,000 lux and below 100,000 lux The image data V1 is displayed using the second display element 550 (i, j) in a brighter manner than when the illuminance is lower than 5 kiloluxes.

〈〈 third display method 〉〉

Specifically, as the third display method, a method of displaying using the first display element 750 (i, j) and the second display element 550 (i, j) can be used. This can reduce power consumption. Alternatively, the image can be displayed well in a dim environment. Alternatively, photos and the like can be displayed with good color reproducibility. Alternatively, fast-moving motion pictures can be displayed smoothly. Alternatively, a display that is comfortable for the user can be performed.

Here, the function of adjusting the brightness of the display by using the first display element 750 (i, j) and the second display element 550 (i, j) for display is called a dimming function. For example, a display element having a function of emitting light may be used to supplement the brightness of the reflective display element.

In addition, the function of adjusting the display color by performing display using the first display element 750 (i, j) and the second display element 550 (i, j) is called a color adjustment function. For example, a display element having a function of emitting light may be used to change the color of the reflective display element. Specifically, a yellow organic EL element can be used to bring the yellowish color displayed by the reflective liquid crystal element closer to white. Thereby, for example, text data can be displayed as if text was printed on plain paper. Alternatively, a display with less eye irritation can be realized.

In addition, when the first display element 750 (i, j) and the second display element 550 (i, j) are used for display, the color emitted by the object is displayed. Color and the color that the object emits together. Thereby, a paint-like display can be realized.

The image data V1 displayed using the second display element 550 (i, j) to be displayed in a manner superimposed on the image data V1 displayed using the first display element 750 (i, j) can be determined according to the illuminance data and the user's preference. Of brightness. Therefore, a display that is comfortable for the user can be performed.

Note that it is also possible to detect the color temperature or chromaticity of the ambient light instead of the ambient illuminance.

[Seventh step]

In a seventh step, a display method is determined based on the detected illuminance data. For example, when the illuminance is greater than a specified value, the first display method is selected, and when the illuminance is lower than the specified value, the second display method is selected. Alternatively, when the illuminance is within a specified range, a third display method may be selected (see FIG. 24B (S7)).

Specifically, when the illuminance is above 100,000 lux, the first display method is selected, and when the illuminance is below 5,000 lux, the second display method is selected. When the illuminance is above 5,000 lux and below 100,000 lux, select The third display method.

In addition, when the color temperature of the ambient light or the chromaticity of the ambient light is detected in the sixth step, the second display element 550 (i, j) may also be used to adjust the display color in the third display method.

For example, when the first display method is used, the control data SS in the first state is supplied, when the second display method is used, the control data SS in the second state is supplied, and when the third display method is used, the control in the third state is supplied. Information SS.

〈〈 Interrupt Processing 〉〉

The interrupt processing includes the following sixth to eighth steps (see FIG. 25).

[Sixth step]

In the sixth step, when the predetermined event is supplied, the process proceeds to the seventh step, and when the predetermined event is not supplied, the process proceeds to the eighth step (refer to FIG. 25 (U6)). For example, whether a predetermined event is supplied for a predetermined period may be used as a condition. Specifically, the predetermined period may be a period longer than 0 seconds and 5 seconds or less, 1 second or less, or 0.5 seconds or less, and preferably 0.1 seconds or less.

[Seventh step]

In the seventh step, the mode is changed (refer to FIG. 25 (U7)). Specifically, when the first mode was previously selected, the second mode was selected, and when the second mode was previously selected, the first mode was selected.

For example, events such as "click" or "drag" provided by a pointing device such as a mouse, "click", "drag", or "slide" provided by a finger or the like to the touch panel can be used. event.

For example, the position, sliding speed, drag speed, and the like of the slide bar indicated by the pointer may be used to supply parameters of instructions associated with a predetermined event.

For example, a threshold value set in advance may be compared with data detected by the detection unit 250, and the comparison result may be used for an event.

Specifically, a pressure-sensitive detector or the like that is in contact with a button or the like that can be pressed into the housing can be used for the detection section 250.

〈〈 Instructions Related to Scheduled Events 〉〉

For example, you can associate an end instruction with a specified event.

For example, a “page turning instruction” that switches one displayed image material to another image material may be associated with a predetermined event. In addition, a predetermined event may be used to supply a parameter for determining a page turning speed and the like used when the "page turning instruction" is executed.

For example, it is possible to associate a predetermined event with a display position of a part of the moving image data and a “scroll instruction” displaying other parts continuous with the part. In addition, a predetermined event may be used to supply a parameter that determines the speed of moving the display position and the like used when the "scroll instruction" is executed.

For example, a command to set a display method or a command to generate image data may be associated with a specified event. In addition, a parameter that determines the brightness of the generated video may be associated with a specified event. In addition, a parameter of the brightness of the generated video may be determined based on the brightness of the environment detected by the detection section 250.

For example, a command such as the use of the communication unit 290 to obtain data transmitted using the push service may be associated with a predetermined event.

In addition, the position data detected by the detection section 250 may be used to determine whether or not the data is eligible for acquisition. Specifically, when users are in designated classrooms, schools, conference rooms, businesses, houses, etc., they can also be judged to be eligible for information. Thereby, for example, a teaching material transmitted in a classroom such as a school or a university can be received to use the data processing device 200 as a textbook or the like (see FIG. 23C). Alternatively, the materials transmitted to the conference room of a company or the like can be received and used for conference materials.

In addition, even if independent components are electrically connected to each other on a circuit diagram, one component may function as a plurality of components. For example, when a part of the wiring is used as an electrode, one conductive film has the functions of both components of the wiring and the electrode. Therefore, the category of "electrical connection" in this specification also includes a case where such a conductive film has functions of a plurality of components.
