移位寄存器单元、栅极驱动装置、显示装置和驱动方法
摘要：
一种移位寄存器单元、栅极驱动装置、显示装置和驱动方法。移位寄存器单元包括：输入模块，基于输入信号控制上拉控制节点的电位；下拉控制模块，在第一信号为第一电平期间，基于输入信号、上拉控制节点的电位，控制下拉控制节点的电位；下拉模块，基于所述下拉控制节点的电位，对所述上拉控制节点的电位进行下拉；上拉模块，基于所述上拉控制节点的电位和所述时钟信号，控制从信号输出端输出的输出信号；以及复位模块，在第二信号为第二电平期间，基于下拉控制节点的电位对所述输出信号进行复位。根据本发明的移位寄存器单元、栅极驱动装置、显示装置和驱动方法，能够提高移位寄存器单元的稳定性，提高移位寄存器单元的使用寿命。
摘要（英）：

A shift register unit, gate driving device, display device and driving method are provided. The shift register unit includes: an input circuit, configured to control a potential of a pull-up control node based on an input signal; a pull-down control circuit, configured to control a potential of a pull-down control node based on the input signal and the potential of the pull-up control node when first signal is at a first level; a pull-down circuit, configured to pull down the potential of the pull-up control node based on the potential of the pull-down control node; a pull-up circuit, configured to control an output signal output from a signal output terminal based on the potential of the pull-up control node and the clock signal; and a reset circuit, configured to reset the output signal based on the potential of the pull-down control node when second signal is at a second level.
