摘要： A gate driver is disclosed. The disclosed gate driver includes a shift register configured to generate a shift signal. The shift signal is based on a gate start signal and a gate clock signal. The gate driver further includes a gate drive signal generator configured to generate a gate drive signal. The gate drive signal is based on a gate control signal and the shift signal. The rising edge of the gate control signal precedes the falling edge of the shift signal, and the falling edge of the gate control signal follows the falling edge of the shift signal. The gate drive signal falls from a second voltage to a third voltage in response to the falling edge of the shift signal and rises from the third voltage to a first voltage in response to the falling edge of the gate control signal. The first voltage is higher than the third voltage but lower than the second voltage.
