栅极驱动单元、栅极驱动方法、栅极驱动电路和显示装置
摘要：
本发明提供一种栅极驱动单元、栅极驱动方法、栅极驱动电路和显示装置。栅极驱动单元包括输入端、锁存节点控制电路、第一节点电位维持电路和锁存节点复位电路，锁存节点控制电路在输入端提供的输入信号的控制下，通过所述锁存充电端输入的充电电压，控制所述锁存节点的电压；第一节点电位维持电路在锁存节点的电压的控制下，控制第一节点与锁存使能端之间连通，维持第一节点的电位；锁存节点复位电路在锁存节点复位端输入的锁存节点复位信号的控制下，控制对锁存节点的电位进行复位。本发明在锁存时间段能够维持第一节点的电位，在锁存时间段之后的显示时间段能够实现正常显示。
摘要（英）：

The invention provides a gate driving unit, a gate driving method, a gate driving circuit and a display device. The gate driving unit comprises an input end, a latch node control circuit, a first nodepotential maintaining circuit and a latch node reset circuit, wherein under control of an input signal provided by the input end, the latch node control circuit controls a voltage of the latch node through a charging voltage input by the latch charging end, under control of the voltage of the latch node, the first node potential maintaining circuit controls connection between a first node and a latch enabling end, and maintains potential of the first node, under control of a latch node reset signal input in a latch node reset end, the latch node reset circuit controls reset of potential of the latch node. The potential of the first node can be maintained in a latch duration, and normal display is realized in a display duration after the latch duration.
