Abstract:
A gate driving circuit for providing a scan signal to a LCD panel is disclosed. The gate driving circuit includes a positive level shifter, a capacitive coupling level shifter, a P-type transistor and an N-type transistor. The positive level shifter shifts up a gate control signal to generate a first control signal. The capacitive coupling level shifter shifts up and down the first control signal to generate positive and negative control signals. The P-type transistor P-type transistor receives the negative control signal and a negative power voltage. The N-type transistor receives the negative control signal and a negative power voltage. An absolute value of a voltage difference between the positive power voltage and the positive control signal and an absolute value of a voltage difference between the negative power voltage and the negative control signal are less than a medium voltage device endurance limit.
