摘要:
A shift register including a plurality of stages, each of them including a first node, a second node, and a third node being in a high-impedance state when the first node is in a high-impedance state. The shift register includes an input circuit unit inputting a driving voltage to the first node in response to an output signal of a previous stage, a driving circuit unit generating an output signal according to a voltage of the first node, and a holding unit holding the output signal at a level of a gate-off voltage according to a voltage of the second node in an inactive period of a current stage, in which the holding unit comprises a first diode which applies a clock signal to the second node.
摘要(中):
一种移位寄存器,包括多个级,每个级包括第一节点,第二节点和第三节点,当第一节点处于高阻抗状态时处于高阻抗状态。 移位寄存器包括输入电路单元,其响应于前一级的输出信号向第一节点输入驱动电压,驱动电路单元根据第一节点的电压产生输出信号,以及保持单元, 输出信号在当前级的无效时段期间根据第二节点的电压的栅极截止电压的电平,其中保持单元包括向第二节点施加时钟信号的第一二极管。
