Abstract
The disclosure discloses a GOA circuit and a liquid crystal display apparatus. The GOA circuit includes a number of GOA unit in cascade connection, wherein the Nth level GOA unit includes a common signal point control module, a gate signal point control module, and a GAS signal operation module; wherein the common signal point control module is used to pull up the electrical level of the common signal point after the period of all gate on; a gate signal point control module is used to pull down the electrical level of a gate signal point after the period of all gate on; the GAS signal operation module is used to achieve the all gate on function by a first GAS signal and a second GAS signal to control the output of the Nth level gate driving signal in the touch panel scanning period.
