Abstract
The invention provides a gate driving circuit for an in-cell touch panel to improve the issue wherein the undesired falling time of a pre-stage shift register and the undesired rising time of a next-stage shift register during a touch sensing period, in which the undesired falling time and the undesired rising time are caused by the output signal of the shift register cannot be correctly transmitted to the pre-stage shift register and the next-stage shift register during the touch sensing period.
