Abstract:
A display device can include a display panel touch block groups, each including touch sensors, each touch sensor corresponds to one or more pixels defined by data lines and gate lines; a data driver that generates and supplies a modulated source signal for display data to a data line; a gate driver that generates a modulated scan-on signal for writing the modulated source signal to a pixel and supplies the modulated scan-on signal to the gate lines; and a touch sensor driver that supplies a touch driving signal to touch wires connected to corresponding touch sensors in each of the touch block groups, and selectively senses for touch on a touch block group, except for a restricted touch block group overlapping a gate line that is supplied with the modulated scan-on signal, in which the modulated source signal or the modulated scan-on signal is synchronized with the touch driving signal.
