Patent ID: 7173599

Claim:
A method for displaying an image in the transmissive-type liquid crystal display device comprising a liquid crystal display and a backlight to emit light to said liquid crystal display from a rear of said liquid crystal display, said method comprising: providing an image signal defining the image; detecting motion in the image based on the image signal; and controlling each of a plurality of electrodes in the liquid crystal display by alternately providing each of the electrodes with the image signal and a non-image signal, wherein the alternation between the image and non-image signals is based on the detected motion; wherein the image is made up of a plurality of windows defined by the image signal, and, based on the detecting step, the controlling step controls each of the electrodes so that those of said electrodes corresponding to one of the windows can be controlled differently from others of said electrodes corresponding to another of the windows; and wherein, based on said detecting step, when said image is determined to be a moving picture, said image signal and said non-image signal are fed during one frame period to said plurality of data electrodes and, when said image is determined to be a still image, said image signal only is fed during said one frame period two or more times to said plurality of data electrodes.
