Abstract
A touch display device includes a touch display panel for displaying an image corresponding to a touch applied from outside the touch display device, a gate driver for sequentially driving all gate lines of the touch display panel once during a unit field period including at least two continuous field periods, in such a manner that a total gate driving period corresponding to a sum of individual gate driving periods of all gate lines is shorter than the unit field period, and a touch control unit for defining periods of the unit field period other than the total gate driving period, as a touch sensing period, and performing an operation for sensing a touch on the touch display panel during the touch sensing period.
