栅极驱动电路和使用栅极驱动电路的液晶显示器
摘要：
一种栅极驱动电路，其包含数个GOA电路单元。每一级GOA电路单元包含锁存模块，用来锁存所述第一控制节点的电平。所述锁存模块包含第一晶体管和第二晶体管。因为锁存模块的第一晶体管和第二晶体管不仅能将第一控制节点的电压锁存在高电平，同时因为晶体管在第一控制节点和高电平的第一固定电压之间形成直流通路，因此第一控制节点的电压不会因漏电而降低。因此本发明解决现有技术采用电容的GOA电路单元容易发生漏电的技术问题，具有提升GOA电路单元输出扫描信号稳定性的有益效果。
摘要（英）：

A gate driver on array (GOA) circuit, comprising a plurality of GOA circuit units. Each stage of GOA circuit units comprises a latching module (200) for latching the level of a first control node (Q(n)). The latching module (200) comprises a first transistor (T1) and a second transistor (T2). The first transistor (T1) and the second transistor (T2) of the latching module (200) can form a direct current path between the first control node (Q(n)) and a high-level first fixed voltage (V1) while latching the voltage of the first control node (Q(n)) at a high level, so that the voltage of the first control node (Q(n)) is not reduced due to electric leakage. Therefore, the GOA circuit resolves the predisposition to electric leakage in the prior art caused by GOA circuit units using capacitors, and improves the stability of scan signals output by the GOA circuit units.
