Patent ID: 7002543

Claim:
A method for driving an active matrix type liquid crystal display, wherein in said active matrix type liquid crystal display, liquid crystal is sealed between a first substrate and a second substrate; said first substrate comprises switching elements and pixel electrodes connected to said switching elements, both of which are provided in correspondence to pixels that are arranged in a matrix, selection lines for sequentially selecting said switching elements, and data lines for supplying display data to said switching elements that are connected; and said second substrate comprises an opposing electrode for controlling, in conjunction with each of said pixel electrodes on said first electrode, said liquid crystal, said method comprising: periodically changing, in a predetermined period, an opposing electrode voltage, which is applied to said opposing electrode; applying a change alleviating voltage to said data lines when said opposing electrode voltage is changed, wherein said change alleviating voltage is a predetermined voltage for alleviating a change in voltage on said data lines, which is independent from said display data; setting a data line voltage on said data lines to said change alleviating voltage; and maintaining said data line voltage at said change alleviating voltage when said opposing electrode voltage changes through application of said change alleviating voltage on said data lines.
