DISPLAY DEVICE HAVING TOUCH PANEL

摘要

A touch display device comprises a controller (22) 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 (AA) 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 (20) supplies gate pulses to gate lines (GL) of the touch panel during the display period and supplies a gate line auxiliary drive signal (ATS1) from a first transfer line (VGLL) onto the gate lines during the touch sensing period that mimics a touch drive signal (TS). One or more auxiliary lines (AL) supply a supplemental auxiliary drive signal (ATS3) during the touch sensing period that mimics the touch drive signal.
