Abstract
In a display device foldable along a folding axis, the display device includes: a display panel configured to display an image at a display region; and a touch unit configured to sense a touch input at the display region, and sense a folding state of the display device, wherein the touch unit includes: a plurality of first sensors arranged in a matrix on a same plane; and a second sensor overlapping the folding axis, the second sensor comprising a conductive line of which at least a portion is bent.
Claims19
A display device foldable along a folding axis, the display device comprising:
- a display panel configured to display an image at a display region;
- and
- a touch unit configured to sense a touch input at the display region, and sense a folding state of the display device,
- wherein the touch unit comprises:
- a plurality of first sensors arranged in a matrix on a same plane and overlapping the display region at a touch active region;
- and
- a second sensor overlapping the folding axis at a touch non-active region outside of the touch active region, the second sensor comprising a conductive line, wherein a first end of the conductive line is connected to a first pad at the touch non-active region and extends to the folding axis where at least a portion of the conductive line is bent and extends, from the at least the portion of the conductive line that is bent in the touch non-active region, to a second pad adjacent the first pad in the touch non-active region without passing through the touch active region.
A method for driving a display device foldable along a folding axis, the method comprising:
- displaying an image on a display panel;
- acquiring a folding sensing signal from a second sensor in a touch unit;
- and
- controlling display of an image on the display panel with reference to the folding sensing signal,
- wherein the second sensor comprises a conductive line, wherein a first end of the conductive line is connected to a first pad at a touch non-active region and extends to the folding axis where at least a portion of the conductive line is bent and extends from the at least the portion of the conductive line that is bent in the touch non-active region to a second pad adjacent the first pad in the touch non-active region without passing through a touch active region,
- wherein the folding sensing signal comprises a change in resistance of the second sensor.
