Zusammenfassung:The invention discloses a gate drive circuit and a display panel, the gate drive circuit comprises a plurality of cascaded gate drive units, the Nth gate drive unit comprises a pull-up transistor, a touch transistor and a potential holding unit, the potential holding unit is switched on in a touch stage, and the pull-up transistor is connected with the potential holding unit. The high-potential signal transmitted in the high-potential line can be output to the pull-up node, the high-potential signal can be continuously injected to the pull-up node, and then it can be guaranteed that the pull-up node maintains the high potential in the touch control stage. 本申请公开了一种栅极驱动电路及显示面板,该栅极驱动电路包括多个级联的栅极驱动单元,其中,第N级栅极驱动单元包括上拉晶体管、触控晶体管以及电位保持单元,通过在触控阶段导通电位保持单元,可以将高电位线中传输的高电位信号输出至上拉节点,能够持续向上拉节点注入高电位信号,进而能够保证上拉节点在触控阶段中维持高电位。
