Method for driving liquid crystal display reducing ic area cost of a source driver ic layout

Abstract

A method for driving a liquid crystal display reducing IC area cost of a source driver IC layout is provided, in which a plurality of common voltage electrodes are configured in the display panel. The method includes the following steps of applying a first voltage to at least one of the common voltage electrodes in a first frame period and applying a second voltage to the at least one of the common voltage electrodes in a second frame period. The first and second voltage are different. The method is applicable to a source driver structure of the display panel, and by employing the method, a voltage level of a source driving signal of the source driver is controlled to be positive and only positive-voltage domain circuit is required in the layout configuration. As a result, the invention is effective in reducing IC area cost and avoiding redundant area waste.
