摘要： A shift register of an LCD device operates based on two clock signals and maintains the gate voltage of an output transistor switch using two pull-down transistor switches. The gate voltages of the pull-down transistor switches are switched periodically between the high and low level of the clock signals. During the output period, the transistor switches have negative gate-source voltages so as to reduce leakage.
