Abstract
A liquid crystal display using dynamic emission device as backlight source includes a field emission device and a liquid crystal panel. The field emission device is divided into plural field emission sections formed as a chessboard. The surface of the field emission device is attached to the liquid crystal panel. Wherein, each field emission section is corresponded to each image-displaying section on the liquid crystal panel. According to the lightness variation of each image-displaying section, each field emission section dynamically compensates the lightness of each image-displaying section. Thereby, the objective of enhancing the dynamic range of the liquid crystal display is achieved.
