Abstract
A liquid crystal display (LCD) device and a driving method thereof are disclosed. In order to obtain high-quality images, a signal preprocessor is incorporated in the gray signal modulator of conventional LCDs. The signal preprocessor can be specifically designed as a noise-reduction preprocessor for suppressing the noise induced from the input gray signals, or designed for detecting a certain character of input gray signals for further processes. After be processed by the signal preprocessor, optimized modified gray signals can be obtained from the signal converter for driving the LCD, thereby producing high-quality images.
