  • Publication number: 20160026312
    Abstract: A touch display device comprises a controller to generate a touch sync signal for controlling timing of a touch sensing period and a display period. A touch panel has a plurality of touch electrodes in a display area of the touch display device. The touch panel generates touch sensing signals indicating whether or not a touch occurs during the touch sensing period. A gate driver supplies gate pulses to gate lines of the touch panel during the display period and supplies a gate line auxiliary drive signal from the first transfer line onto the gate lines during the touch sensing period that mimics the touch drive signal. One or more auxiliary lines supply a supplemental auxiliary drive signal during the touch sensing period that mimics the touch drive signal.
