移位寄存器及其驱动方法、发射驱动电路和显示装置
摘要：
本发明实施例提供一种移位寄存器，涉及显示技术领域。本发明实施例提供的移位寄存器包括：第一节点控制模块，用于根据输入信号、第一时钟信号和第二时钟信号，控制第一节点的电平状态；第二节点控制模块，用于根据输入信号、第一时钟信号、第二时钟信号、高电平信号和第一节点的电平状态，控制第二节点的电平状态，其中，在输入信号为高电平，且第一时钟信号为低电平的每个阶段，提供高电平至用以控制第二节点的电平的第三节点，以使在输入信号为高电平，且第二时钟信号为低电平的每个阶段，拉低第三节点的电平，以提供低电平至第二节点。本发明的技术方案能够在采用dimming模式，输入信号长高时，保证移位寄存器的正常工作。
摘要（英）：

Provided is a shift register, including a first node control module for controlling a level state of a first node based on an input signal, a first clock signal and a second clock signal. The shift register includes a second node control module for controlling a level state of a second node based on the input signal, the first clock signal, the second clock signal and the level state of the first node. In a phase when the input signal is at high level and the first clock signal is at low level, a third node for controlling a level at the second node is provided with high level, such that in a phase when the input signal is at high level and the second clock signal is at low level, the level at the third node is pulled down so as to provide low level at the second node.
