Abstract
A gate driver circuit for eliminating power-off residual image form a display device is provided. The gate driver circuit comprises a first capacitor, a diode, a second capacitor and a regulator circuit. The first capacitor filters out high frequency surge and high frequency noise of an input voltage. The diode receives the input voltage and charges up the second capacitor by forwarding charges to the second capacitor. The diode also provides an input voltage to the regulator circuit. Finally, the voltage level transformer of the regulator circuit transmits an output voltage to the logic circuit of the display device.
