Abstract

A data processing device which includes a flexible position input portion for sensing proximity or a touch of an object such as a user'"'"'s palm and finger. In the case where a first region of the flexible position input portion is held by a user for a certain period, supply of image signals to the first region is selectively stopped.

Claims

1. A portable device comprising:

a display panel configured to display an image over a front surface and a first side surface of the portable device;

a sensor portion configured to sense touch of an object over the front surface and the first side surface of the portable device; and

an arithmetic portion configured to determine whether touch in a region of the display panel corresponds to an intentional input of a user and selectively stop supply of an image signal to the region,

wherein a part of the display panel is curved toward a back surface of the portable device, and

wherein the arithmetic portion is on and in contact with the part of the display panel.

2. The portable device according to claim 1, wherein touch in the region is identified as an unintentional input when the portable device is held by the user for a certain period.

3. The portable device according to claim 1, wherein the part of display panel is curved in conformity with the first side surface of the portable device.

4. The portable device according to claim 1, wherein the display panel is configured to display the image over a second side surface opposite to the first side surface of the portable device.

5. A portable device comprising:

a display panel configured to display an image over a front surface and a first side surface of the portable device;

a sensor portion configured to sense touch of an object over the front surface and the first side surface of the portable device; and

an arithmetic portion configured to determine whether touch in a region of the display panel corresponds to an intentional input of a user and selectively stop supply of an image signal to the region,

wherein a part of the display panel is curved toward a back surface of the portable device,

wherein the sensor portion comprises a plurality of sensors over a flexible substrate,

wherein a part of the flexible substrate is curved toward the back surface of the portable device, and

wherein the arithmetic portion is on and in contact with the part of the display panel.

6. The portable device according to claim 5, wherein touch in the region is identified as an unintentional input when the portable device is held by the user for a certain period.

7. The portable device according to claim 5, wherein the part of display panel is curved in conformity with the first side surface of the portable device.

8. The portable device according to claim 5, wherein the display panel is configured to display the image over a second side surface opposite to the first side surface of the portable device.

9. A portable device comprising:

a display panel configured to display an image over a front surface and a first side surface of the portable device;

a sensor portion configured to sense touch of an object over the front surface and the first side surface of the portable device; and

an arithmetic portion configured to determine whether touch in a region of the display panel corresponds to an intentional input of a user and selectively stop supply of an image signal to the region,

wherein a part of the display panel is curved toward a back surface of the portable device,

wherein the arithmetic portion is on and in contact with the part of the display panel, and

wherein the display panel is folded in three such that a first portion, a second portion, and a third portion of the display panel overlap with each other.

10. The portable device according to claim 9, wherein touch in the region is identified as an unintentional input when the portable device is held by the user for a certain period.

11. The portable device according to claim 9, wherein the part of display panel is curved in conformity with the first side surface of the portable device.

12. The portable device according to claim 9, wherein the display panel is configured to display the image over a second side surface opposite to the first side surface of the portable device.

13. The portable device according to claim 9, wherein the display panel is folded between the first portion and the second portion and between the second portion and the third portion.
