Abstract

一种移位寄存器单元(10)、栅极驱动电路(20)、显示装置(1)及驱动方法。移位寄存器单元(10)包括输入电路(110)、第一控制电路(120)、消隐控制电路(130)、第一输出电路(141)和第二输出电路(142)。输入电路(110)配置为响应于输入信号对第一节点(Q1)的电平进行控制；第一控制电路(120)配置为响应于输入信号以及第一节点(Q1)的电平，对第二节点(Q2)的电平进行控制；消隐控制电路(130)配置为对第一节点(Q1)的电平和第二节点(Q2)的电平进行控制；第一输出电路(141)配置为在第一节点(Q1)的电平的控制下，在第一输出端(OUT1)输出第一输出信号；第二输出电路(142)配置为在第二节点(Q2)的电平的控制下，在第二输出端(GOUT2)输出第二输出信号。该移位寄存器单元(10)可以节省晶体管和电容的数目，从而使得采用该移位寄存器单元(10)的显示装置(1)可以减小边框尺寸。
