移位寄存器单元及其驱动方法、栅极驱动电路和显示装置
摘要：
本公开实施例公开了一种移位寄存器单元及其驱动方法、栅极驱动电路和显示装置。移位寄存器单元包括：输入电路，被配置成将信号输入端接收的输入信号输出至上拉节点；输出电路，被配置成在时钟信号的控制下在信号输出端输出栅极驱动信号；第一复位电路，被配置成在第一复位信号的控制下将上拉节点复位至第一电平；第一下拉控制电路，被配置成在第一控制信号的控制下控制上拉节点和信号输出端的电平；以及第一波形控制电路，具有接收第二控制信号的第二控制信号端，被配置成在第二控制信号的控制下控制第一下拉节点的电压信号波形。
摘要（英）：

The embodiment of the invention discloses a shift register unit, a drive method therefor, a gate drive circuit, and a display device. The shift register unit comprises an input circuit which is configured to output an input signal received at a signal inputting end to a pull-up node; an output circuit which is configured to output a gate drive signal at the signal output end under the control of the clock signal; a first resetting circuit which is configured to reset the pull-up node to a first level under the control of the first resetting signal; a first pull-down control circuit which is configured to control the level of the pull-up node and the signal output end under the control of the first control signal; and a first waveform control circuit which has a second control signal end for receiving a second control signal, and is configured to control the voltage signal waveform of the first pull-down node under the control of the second control signal.
