ABSTRACT:
A gate driving circuit and a power control circuit are disclosed. The gate driving circuit includes a gate driver and the power control circuit. The gate driver is adapted for receiving a starting signal and sequentially outputting a plurality of scan signals accordingly. The power control circuit includes a delay circuit, a level shifter and a switch unit. The delay circuit is adapted for receiving and delaying the starting signal for a predetermined period and then outputting the delayed starting signal. The level shifter receives and adjusts a voltage level of the delayed starting signal, and outputs a starting voltage accordingly. The switch unit provides the first power to the gate driver after being delayed for the predetermined period according to the starting voltage.
