Display device having touch sensor embedded in pixel array and method of driving the same
First Claim
1. A display device comprising:
- a display panel comprising (i) a pixel array comprising a plurality of pixels and (ii) a touch sensor array comprising a plurality of touch sensors formed in the pixel array, the pixel array and the touch sensor array being divided into a plurality of blocks;
a gate driver to sequentially drive a plurality of gate lines in the pixel array in a block unit;
a data driver to drive a plurality of data lines in the pixel array when the gate lines are driven;
a touch controller to sequentially drive the touch sensor arrays in the block unit; and
a timing controller (i) to divide one frame into at least one display mode at which the pixel array is driven, and at least one touch sensing mode at which the touch sensor array is driven, and (ii) to control the gate drive, the data driver and the touch controller so that the display mode and the touch sensing mode alternate,wherein;
the gate driver drives none of the gate lines in the plurality of blocks during the touch sensing mode of the block unit in response to a mode switching signal, andthe data driver drives none of the data lines in the plurality of blocks during the touch sensing mode of the block unit in response to the mode switching signal.
