DISPLAY DEVICE INCLUDING TOUCH SENSOR AND DRIVING METHOD THEREOF
A display device including a touch sensor and a driving method thereof, and more particularly, a curved display device including a touch sensor and a driving method thereof, are presented. The display device includes: a touch sensor unit including a plurality of touch sensors; and at least one touch surface curved to along a first direction, wherein the touch surface includes a center region and edge regions positioned at both sides of the center region along the first direction, and wherein a sensitivity of the touch sensor in the center region is higher than a sensitivity of the touch sensors in the edge regions.
1 . An organic light emitting display device comprising:
a display panel comprising a plurality of pixels, a plurality of signal lines and a plurality of thin film transistors, the plurality of pixels including a plurality of light emitting layers between pixel electrodes and an opposed electrode;
an encapsulation layer on the display panel;
an insulating layer on the encapsulation layer; and
a touch sensor unit including a plurality of touch sensors and a plurality of touch wires on the insulating layer, wherein
the display panel is concavely curved along a first direction,
the insulating layer is concavely curved along the first direction,
the encapsulation layer includes at least one inorganic insulating layer and an organic insulating layer,
the touch sensor unit includes a center region and edge regions positioned at both sides of the center region along the first direction,
the display panel is substantially entirely overlapped with the touch sensor unit, and
a sensitivity of the touch sensor in the center region is higher than a sensitivity of the touch sensor in the edge regions in a hovering touch mode.
