Method of setting common electrode voltage of liquid crystal display panel, and liquid crystal module

Abstract

A method of setting a common electrode voltage of a liquid crystal display panel in a liquid crystal module is provided. The liquid crystal module includes the liquid crystal display panel including an alignment film, and a backlight disposed behind the liquid crystal display panel. The method of setting a common electrode voltage of a liquid crystal display panel includes: eliminating an electric charge of the alignment film by turning on the backlight without driving the liquid crystal display panel to emit light of the backlight onto the liquid crystal display panel; and setting the common electrode voltage of the liquid crystal display panel by adjusting the common electrode voltage, after the eliminating of the electric charge.
