Abstract: The present application provides a gate driver circuit comprising at least one cascaded gate driver circuit unit. The low-level-holding enabling terminal of the gate driver circuit unit is connected to an adaptive voltage generating module. The adaptive voltage generating module generates a self-compensating voltage according to its constant current source and transmits to the low-level-holding enabling terminal, so as to provide an effective voltage level to the low-level-holding enabling terminal. Because the threshold voltage shift caused by pulling-down transistors in the low-level-holding module is embodied at the low-level-holding enabling terminal, the adaptive voltage generating module generates a self-compensating voltage with its constant current source according to the threshold voltage to compensate the increase of the threshold voltage.
