Zusammenfassung:The invention discloses a GOA circuit and a display panel. The GOA circuit comprises multiple stages of cascaded GOA units, each GOA unit comprises a pull-up control module, a pull-down maintenance module, a pull-down module, a bootstrap capacitor, a pull-up module and a download module. The GOA circuit uses an alternating current signal driving circuit with opposite high and low signal potentials in the pull-up module, a signal is pulled down for stress recovery in the blank time of the scanning signal, threshold voltage offset caused by high potential stress during display is reduced, the stability of the circuit is improved, and the service life of the circuit is prolonged. 本申请公开了一种GOA电路及显示面板,GOA电路包括多级级联的GOA单元,每一GOA单元包括上拉控制模块、下拉维持模块、下拉模块、自举电容、上拉模块以及下传模块,所述GOA电路在所述上拉模块使用高低信号电位相反的交流信号驱动电路,在扫描信号的空白时间拉低信号进行应力回复,降低显示时候的高电位应力造成的阈值电压偏移,提高电路的稳定性和使用寿命。
