Abstract

To provide a highly browsable data processing device, provide a highly portable data processing device, provide a data processing device which consumes low power, or provide a data processing device having high display quality, the data processing device includes a display portion having flexibility, a plurality of driver circuit portions arranged in the periphery of the display portion, a sensor portion discerning an external state of the display portion, an arithmetic portion supplying image data to the driver circuit portions, and a memory portion storing a program executed by the arithmetic portion. A first mode in which the display portion is unfolded or a second mode in which the display portion is folded is sensed by the sensor. Luminance adjustment processing is carried out by the program in accordance with the first mode or the second mode.

First claim

The invention claimed is:

1. A data processing device comprising:
a display portion having flexibility;
a plurality of driver circuit portions;
a sensor portion discerning an external state of the display portion;
an arithmetic portion supplying image data to the plurality of driver circuit portions; and
a memory portion storing a program executed by the arithmetic portion,
wherein a first mode in which the display portion is unfolded or a second mode in which the display portion is folded is sensed by the sensor portion,
wherein the display portion includes a first screen surface, a second screen surface and a third screen surface between the first screen surface and the second screen surface,
wherein, in the second mode, the first screen surface of the display portion is configured to face outside and overlap the third screen surface, and
wherein, in the second mode, a plurality of light-emitting regions whose luminance becomes higher toward the first screen surface from the third screen surface are interposed between the first screen surface and the third screen surface.

2. The data processing device according to claim 1 , the program comprising:
a first step of specifying the external state;
a second step in which the program proceeds to a fifth step in the case of the first mode or a third step in the case of a mode other than the first mode;
the third step in which the program proceeds to a fourth step in the case of the second mode or the first step in the case of a mode other than the second mode;
the fourth step of carrying out a luminance adjustment processing; and
the fifth step of terminating the program,
the luminance adjustment processing comprising:
a sixth step of deciding a display region and a non-display region;
a seventh step of stopping at least one of the plurality of driver circuit portions;
an eighth step of emitting light from part of the non-display region;
a ninth step in which the program proceeds to a tenth step in the case where the luminance adjustment processing is canceled or the eighth step in the case where the luminance adjustment processing is not canceled; and
the tenth step of recovering from the luminance adjustment processing to the program.

3. The data processing device according to claim 1 , wherein the display portion includes a light-emitting element.

4. The data processing device according to claim 1 , wherein the display portion includes an organic EL element.

5. A data processing device comprising:
a display portion;
a plurality of driver circuit portions;
a sensor portion discerning an external state of the display portion;
an arithmetic portion supplying image data to the plurality of driver circuit portions; and
a memory portion storing a program executed by the arithmetic portion,
wherein a first mode in which the display portion is unfolded or a second mode in which the display portion is folded is sensed by the sensor portion,
wherein the display portion includes a first screen surface, a second screen surface and a third screen surface between the first screen surface and the second screen surface,
wherein, in the second mode, the first screen surface of the display portion is configured to face outside and overlap the third screen surface, and
wherein, in the second mode, a plurality of light-emitting regions whose luminance becomes higher toward the first screen surface from the third screen surface are interposed between the first screen surface and the third screen surface.

6. The data processing device according to claim 5 , the program comprising:
a first step of specifying the external state;
a second step in which the program proceeds to a fifth step in the case of the first mode or a third step in the case of a mode other than the first mode;
the third step in which the program proceeds to a fourth step in the case of the second mode or the first step in the case of a mode other than the second mode;
the fourth step of carrying out a luminance adjustment processing; and
the fifth step of terminating the program,
the luminance adjustment processing comprising:
a sixth step of deciding a display region and a non-display region;
a seventh step of stopping at least one of the plurality of driver circuit portions;
an eighth step of emitting light from part of the non-display region;
a ninth step in which the program proceeds to a tenth step in the case where the luminance adjustment processing is canceled or the eighth step in the case where the luminance adjustment processing is not canceled; and
the tenth step of recovering from the luminance adjustment processing to the program.

7. The data processing device according to claim 5 , wherein the display portion includes a light-emitting element.

8. The data processing device according to claim 5 , wherein the display portion includes an organic EL element.

9. The data processing device according to claim 1 , wherein an image is displayed on the third screen surface in the first mode, and an image is not displayed on the third screen surface in the second mode.

10. The data processing device according to claim 5 , wherein an image is displayed on the third screen surface in the first mode, and an image is not displayed on the third screen surface in the second mode.

11. The data processing device according to claim 1 , wherein each of the plurality of light-emitting regions extends along a fold.

12. The data processing device according to claim 5 , wherein each of the plurality of light-emitting regions extends along a fold.
