摘要： A display driving circuit includes a timing controller, agate driving circuit, a control unit, a boost converter and a level shifter. The timing controller functions to provide a first start pulse. The level shifter generates a second start pulse by level shifting the first start pulse. The gate driving circuit includes a plurality of shift registers coupled in series and is driven by the second start pulse and the level shifter so as to generate gate signals. The control unit uses the second start pulse and a gate signal generated by a kth shift register to switch a high working voltage provided to the level shifter by the boost converter to a suitable range for driving the gate driving circuit.
