DRIVING APPARATUS OF LIQUID CRYSTAL DISPLAY FOR MODIFYING DIGITAL GRAY DATA BASED ON GRAY DISTRIBUTION AND METHOD THEREOF

摘要

The present invention improves the response speed of the liquid crystal to generate a digital gray scale data in accordance with the gradation distribution of the frame, to improve the picture quality of the video. Therefore, the present invention provides the image data for the provided data to be applied to the display by selecting a gray voltage corresponding to the image data of the plurality of gray scale voltage as a data voltage drive, and the video data to the data driving unit and the frame on the basis of the gray level distribution to generate a digital gray scale data and a control signal to be supplied to the data driver. Therefore, sikimeuro changed based morning brightness difference by adjusting the variation of the luminance for each gray level section-specific gray level distribution in a frame, changing the brightness and the contrast ratio in accordance with the image data of the frame, improving the visibility of the screen accordingly sikimyeo, thereby to enable the display of the dynamic video to meet the needs of users. ; The liquid crystal display, LCD, the gray scale voltages. Contrast ratio, tone distribution
