Abstract

A display position of an image is moved in accordance with positional information of a display device having a curved display surface. Displacement of a display device is sensed by a camera portion and an acceleration sensor, and the display position is determined in accordance with the displacement, so that the image is displayed in the display position. In the case where the display device rotates and the like, a desired piece of information can be displayed automatically in a display region that can be easily seen.

First claim

What is claimed is:

1. A display device comprising:
a band-like object; and
a display surface comprising a front surface and a side surface,
wherein the display surface extends in a short-side direction of the band-like object so as to curve from the front surface to the side surface and extends in a long-side direction of the band-like object,
wherein the display device is configured move an image in the short-side direction and the long-side direction, and
wherein the display device is configured to make luminance in the side surface smaller than luminance in the front surface.

2. The display device according to claim 1 , wherein the display device is configured to selectively turn off display of the side surface.

3. The display device according to claim 1 ,
wherein the display device is configured to switch from a first mode to a second mode by a gesture as a trigger, and
wherein a display position of an image is moved when the display device is moved in one of the first mode and the second mode, and a display position of an image is not moved even when the display device is moved in the other of the first mode and the second mode.

4. The display device according to claim 1 , wherein the display device is a flexible display device.

5. The display device according to claim 1 , wherein the display device is configured to sense operational information on the display surface.

6. A display device comprising:
a band-like object;
a display surface comprising a front surface and a side surface; and
a sensing unit,
wherein the display surface extends in a short-side direction of the band-like object so as to curve from the front surface to the side surface and extends in a long-side direction of the band-like object,
wherein the display device is configured move an image in the short-side direction and the long-side direction,
wherein the display device is configured to make luminance in the side surface smaller than luminance in the front surface, and
wherein the display device is configured to not rewrite an image in the display surface when the sensing unit does not sense displacement of the display device.

7. The display device according to claim 6 , wherein the display device is configured to selectively turn off display of the side surface.

8. The display device according to claim 6 ,
wherein the display device is configured to switch from a first mode to a second mode by a gesture as a trigger, and
wherein a display position of an image is moved when the display device is moved in one of the first mode and the second mode, and a display position of an image is not moved even when the display device is moved in the other of the first mode and the second mode.

9. The display device according to claim 6 , wherein the display device is a flexible display device.

10. The display device according to claim 6 , wherein the display device is configured to sense operational information on the display surface.

11. The display device according to claim 1 ,
wherein the display device is configured to vary luminance in the side surface at different times.

12. The display device according to claim 6 ,
wherein the display device is configured to vary luminance in the side surface at different times.
