ABSTRACT:
Embodiments of the present invention provide a method for driving a liquid crystal display (LCD) device using gray-scale voltages whose dynamic ranges are different from each other depending on pixel color. The gray-scale voltages are output to a source line driver. Embodiments of the invention also provide a gray-scale voltage generation circuit coupled to a LCD source line driver. The disclosed method and circuit reduce coupling phenomena in source lines to substantially remove artifacts such as stripes or flicker in an LCD device.
