Abstract:
A driving circuit configured to drive a display panel having a touch panel is provided. The driving circuit modulates a plurality of first voltage signals on a plurality of different first signals and provides the modulated first signals to the gate control circuit on the display panel. A plurality of gate lines of the display panel are driven according to the modulated first signals during a sensing period. The driving circuit modulates a plurality of second voltage signals on a second signal. The sensor pads of the touch panel are driven according to the modulated second signal during the sensing period. The driving circuit modulates a plurality of third voltage signals on a third signal and provides the modulated third signal to non-active sensor pads during the sensing period. A method for driving a display panel having a touch panel and a display apparatus are also provided.
