ABSTRACT:
A liquid crystal display and method for controlling brightness of an image on a liquid crystal display are provided, in which, a liquid crystal display panel displays an image, a light generating unit provides a laser beam to illuminate the liquid crystal display panel, a scanning unit scans the liquid crystal display panel with the laser beam, and a controller controls a speed of the scanning unit depending on a brightness of the image. Thus, the liquid crystal display is capable of improving a contrast of an image displayed on a liquid crystal panel using a laser as a backlight.
