ABSTRACT:
The present invention relates to a liquid crystal display. The liquid crystal display includes a liquid crystal panel assembly having a plurality of scanning regions that include a plurality of pixels, respectively; a plurality of light source units that include a plurality of light sources supplying light to the plurality of scanning regions, respectively; a data driver that selects gray voltages corresponding to image signals and applies the selected gray voltages to the plurality of pixels as data signals, respectively; and a light source controller that controls the turning on and off of the light sources. One frame is divided into red, green, blue, and black fields, and the light source controller turns off the light source during the black field. Accordingly, the color mixing phenomenon is reduced, and the lighting time of the light source and the charging time of the pixels increase, thereby improving the image quality.
