Title: LIQUID-CRYSTAL PANEL DRIVER CIRCUIT AND DRIVE METHOD THEREOF
Abstract:
Provided is a liquid-crystal panel driver circuit, comprising: a signal controller (600), used for producing a pixel clock signal and adjusting the duty cycle of the pixel clock signal; gate drivers (400), used for receiving the pixel clock signal following adjustment of the duty cycle as well as a reference gate conduction voltage supplied by an external signal source, and according to the pixel clock signal after adjustment of the duty cycle and the reference gate conduction voltage, calculating the actual gate conduction voltage supplied to the gate line. Also provided is a drive method of the liquid-crystal panel driver circuit. The liquid-crystal panel driver circuit and drive method thereof are such that the gate conduction voltages VGH outputted by the gate drivers (400) are the same thereby causing the actual charging time of the regions driven by the gate drivers (400) to be the same, improving the display quality of the liquid-crystal display.
