一种移位寄存器、栅极驱动电路及显示面板
摘要：
本发明公开了一种移位寄存器、栅极驱动电路及显示面板，该种移位寄存器中，上拉模块用于拉高第一节点的电位；下拉模块用于拉低第一节点的电位；第一控制模块用于控制第二节点的电位；第二控制模块维持或降低第一节点的电位；输出模块用于输出扫描信号。这样通过上拉模块、下拉模块、第一控制模块、第二控制模块和输出模块可以实现扫描信号的正常输出，同时通过第二控制模块控制第一节点的电位，在保证输出模块可以在第一节点的控制下正常输出扫描信号的同时，降低第一节点的电位，从而避免第一节点的电位过高造成的移位寄存器输出扫描信号的稳定性较差的问题。
摘要（英）：

The invention discloses a shift register, a grid drive circuit and a display panel, in the shift register, a upper pull module is used r the potential of the first node; a dropdown pull module is used to lower the potential of the first node; a first control module is used to control the potential of the second node; a second module maintain or reduce the potential of the first nod; a output module is used to output the scanning signal. The scanning signal can output normally through the upper pull module, the a dropdown module, the first control module, the second control module and the output module, at the same time, the potential of the first nod is controlled by the second module, in the condition that output module can normally out scanning signal by the first node controlling, the potential of the first node is decreased, therefore, the problem of the poor stability of the shift register outputting scanning signal caused by the higher potential of the first node is avoided.
