Abstract
A shift register includes at least one stage circuit that has at least three voltage control switches, a storage element, and a first clock signal, a second clock signal and a third clock signal to control various switches. Input signals are stored in the capacitor and sequentially transferred to the next stage. During transferring to the next stage, pixel switches of one row on the panel display are activated to receive information delivered from the data end for displaying on the pixels. The clock signals have the characteristics that the first clock signal, second clock signal and third clock signal are not at the same certain potential concurrently to prevent the switches of each stage (the second and third switches) from forming a DC path and burning out.
