移位寄存器和包括该移位寄存器的显示设备
摘要：
本发明提供了一种移位寄存器和具有该移位寄存器的显示设备。所述移位寄存器具有用于顺序产生与多个时钟信号同步的输出信号的多个级。所述多个级中的每一个都包括：输入单元，用于从前一级接收扫描起始信号或输出信号以及输出所述扫描起始信号或所述输出信号来作为第一电压；第一单元，用于通过至少两个时钟信号；第二单元，用于响应于来自下一级的输出信号，输出所述至少两个时钟信号中的至少一个时钟信号或第二电压；以及输出单元，用于响应于所述输入单元和第二单元的输出，产生与所述至少两个时钟信号中的至少一个时钟信号同步的输出信号。
摘要（英）：

A shift register and a display device having the shift register are provided. The shift register has a plurality of stages which sequentially generate output signals in synchronization with a plurality of clock signals. Each of the stages includes an input unit for receiving a scan start signal or an output signal from a previous stage and outputting the scan start signal or the output signal as a first voltage, a first unit for passing at least two clock signals, a second unit for outputting at least one of the at least two clock signals or a second voltage in response to an output signal from a next stage, and an output unit for generating an output signal synchronized with at least one of the at least two clock signals in response to the outputs of the input unit and the second unit.
