Abstract
A method of driving a liquid crystal display panel which is suitable to display a multivalue image such as a television image or the like, including the steps of inverting an image signal every time a horizontal sync signal is generated, applying the image signal to source lines of the display panel, and synchronously applying an inversion control signal to the common opposite electrode of the display panel, thereby remarkably reducing the driving voltage of the source lines. In this manner, a high-speed CMOS device of a low withstanding voltage can be used as an integrated circuit to drive the source lines.
