Abstract:
A display circuit for a liquid crystal display panel is provided. The display circuit comprises a control circuit, a data driving circuit, a partial display mode driving circuit, a scanning circuit, and a liquid crystal display panel. When the LCD works in the partial display mode, the control circuit will stop sending out the shift clock signal for controlling the data driving circuit for the non-display area and will make both ends of the pixel electrodes in the non-display area equipotential. Hence, there is no complicated operation for the data driving circuit, and power consumption and thus be reduced.
