栅极驱动电路及显示面板
摘要：
本发明公开了一种栅极驱动电路和具有此栅极驱动电路的显示面板。栅极驱动电路包含移位寄存器和重设信号线。移位寄存器包含预充电单元、上拉单元和重设单元。预充电单元耦接第一节点，其输出预充电信号至第一节点。上拉单元耦接第一节点与第二节点，其输出扫描信号至第二节点。重设单元耦接第一节点、第二节点和重设信号线。重设信号线提供重设信号至重设单元，以在栅极驱动电路于一个图框时间中对栅极线进行扫描后，重设信号进行电势切换。本发明可避免移位寄存器受到杂讯干扰的影响而输出不正常的扫描信号，确保显示面板显示正确的画面。
摘要（英）：

The invention discloses a gate driving circuit and a display panel having the gate driving circuit. The gate driving circuit includes a shift register and a reset signal line. The shift register includes a precharge unit, a pull-up unit, and a reset unit. The precharge unit is coupled to a first node, and outputs a precharge signal to the first node. The pull-up unit is coupled to the first node and a second node, and outputs a scan signal to the second node. The reset unit is coupled to the first node, the second node and a reset signal line. The reset signal line provides a reset signal to the reset unit to reset the signal for potential switching after the gate driving circuit scans the gate line in a frame time. The circuit can prevent the shift register from being affected by noise interference and outputting an abnormal scan signal, and ensure that the display panel displays a correct picture.
