  • Display device having touch sensor and method of driving the same
    Patent number: 11494030
    Abstract: A display device having touch sensors and a method of driving the same are disclosed. The display device includes a display panel including a pixel array including pixels and a touch sensor array including touch sensors formed in the pixel array, the pixel array being divided into 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 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 to control the gate drive, the data driver and the touch controller so that the display mode and the touch sensing mode alternate.
    Type: Grant
