Abstract
A gate driving circuit for providing a scan signal to a LCD panel is disclosed. The gate driving circuit includes at least one positive level shifter, at least one negative level shifter, a pair of P-type transistor and an N-type transistor. The positive level shifter is utilized for shifting up agate control signal to generate a positive control signal. The negative level shifter is utilized for shifting down the gate control signal to generate a negative control signal. The pair of transistors is utilized for outputting a positive power voltage or a negative power voltage as the scan signal according to the positive control signal and the negative control signal. The positive power voltage minus the positive control signal is less than six volts. The negative control signal minus the negative power voltage is less than six volts.
