Abstract:
1. A display circuit for a liquid crystal display panel, comprising: a data driving circuit having a plurality of data lines coupled to said liquid crystal display panel, wherein when said liquid crystal display panel is scanned to a display area, said data driving circuit sends out a data signal to said liquid crystal display panel via one of said plurality of data lines based on a shift clock signal; a partial display mode driving circuit having a plurality of common voltage output terminals corresponding to and being coupled to said plurality of data lines, wherein when said liquid crystal display panel is scanned to a non-display area, said partial display mode driving circuit receives a partial display mode signal and sends a common voltage to said liquid crystal display panel via said plurality of data lines; and a control circuit coupled to said data driving circuit and said partial display mode driving circuit, said control circuit sending out said shift clock signal to said data driving circuit and said partial display mode signal to said partial display mode driving circuit, wherein when said liquid crystal display panel is scanned to said non-display area, said control circuit stops sending out said shift clock signal and starts to send said partial display mode signal to enable said partial display mode driving circuit.
