Abstract
The present invention of the embodiment provides a drive circuit, comprising a first group of drive circuits and a second group of drive circuits each having multiple stages of gate drive circuits connected in series, each stage of the gate drive circuits comprising a shift register outputting a first gate drive signal and a touch voltage stabilizing unit coupled to the shift register, the touch voltage stabilizing unit comprising a reference end electrically connected to a reference potential of the shift register, a first voltage stabilizing end electrically connected to the first gate drive signal, a second voltage stabilizing end outputting a second gate drive signal and a signal end electrically connected to a control signal, wherein the control signal disables the touch voltage stabilizing unit during a display period, and the control signal enables the touch voltage stabilizing unit during a touch period.
