Abstract

A gate driver with reduced voltage fluctuations driving a display device generates pulse signals shifted in a specified phase. The gate driver includes connected unit circuits. Each unit circuit includes an output terminal, input and output transistors, and a holding module. First and second control signals, alternating oppositely between high and low states, govern the two transistors. The input transistor is controlled by a first control signal and outputs a high level voltage to a first node based on a trigger signal. The output transistor outputs the shifted pulse signal synchronously with a clock control signal, based on the high level voltage of the first node. Initially, the trigger signal is low and the first and second control signals are high. The holding module outputs the low level voltage to the output terminal based on the first control signal and the second control signal.
