    • A gate driver for a liquid crystal display includes a shift register including a plurality of stages for outputting gate drive signals. Each of the stages includes a pull-up circuit for providing the gate drive signal to an output terminal in response to first and second clock signals, a pull-down circuit for providing a gate off signal to the output terminal, a pull-up driving circuit for driving the pull-up circuit in response to a first control signal, and a pull-down driving circuit for driving the pull-down circuit in response to a second control signal. Each of the stages includes a plurality of switching devices. A node of nodes where a signal line, through which the first clock signal, the second clock signal, the first control signal or the second control signal is applied, is electrically connected to a switching device includes at least two contacts.
    • 用于液晶显示器的栅极驱动器包括:移位寄存器,包括用于输出栅极驱动信号的多个级。 每个级包括用于响应于第一和第二时钟信号将栅极驱动信号提供给输出端的上拉电路,用于向输出端提供栅极截止信号的下拉电路,上拉驱动 用于响应于第一控制信号驱动上拉电路的电路,以及用于响应于第二控制信号驱动下拉电路的下拉驱动电路。 每个级包括多个开关装置。 通过其施加第一时钟信号,第二时钟信号,第一控制信号或第二控制信号的信号线,电连接到开关装置的节点的节点包括至少两个触点。
