Abstract
A gate driving circuit includes a thermal sensing unit for sensing temperature to output a sensing voltage, a compare unit for comparing the sensing voltage with a reference voltage to output a control voltage, a charging control module for controlling a pre-charging operation according to the control voltage, and a plurality of shift register stages. Each shift register stage includes an input unit for outputting a driving control voltage according to a first input signal, a clock input unit for outputting a driving voltage according to a system clock, a driving unit for outputting a gate signal according to the driving control voltage and the driving voltage, and a pull-down unit for pulling down the gate signal and the driving control voltage according to a second input signal. The driving voltage is also controlled by the pre-charging operation for enhancing driving ability.
