平面显示器、位移缓存器及其控制方法
摘要：
一种平面显示器、位移缓存器及其控制方法在此揭露，位移缓存器包含多个位移缓存单元，其中至少一位移缓存单元电性耦接前一级位移缓存单元与后一级位移缓存单元，此位移缓存单元包含信号输入电路、信号输出电路、下拉电路与切换电路。信号输入电路，电性耦接前一级位移缓存单元，用以接收一来自前一级位移缓存单元的逻辑信号；信号输出电路，经由一控制信号端电性耦接信号输入电路，且电性耦接后一级位移缓存单元，接收一第一频率信号；切换电路电性耦接下拉电路与控制信号端，其中下拉电路通过切换电路与控制信号端选择性的电性耦接或电性隔离。
摘要（英）：

A shift register includes shift register units, in which at least one shift register unit is coupled to a forestage shift register unit and a post-stage shift register unit, where the at least one shift register unit includes a signal input circuit, a signal output circuit, a pull down circuit and a switching circuit. The signal input circuit electrically coupled to the forestage shift register unit can receive a logic signal from the forestage shift register. The signal output circuit is electrically coupled to the signal input circuit via a control signal terminal and is electrically coupled to the post-stage shift register unit. The signal output to circuit can receive a first clock signal. The pull down circuit is electrically coupled to or electrically isolated from the control signal terminal through the switching circuit.
