Greyscale value setting method for liquid crystal panel and liquid crystal display

摘要

A grayscale value setting method for a liquid crystal panel is disclosed which includes obtaining actual luminance values of each grayscale G of the liquid crystal panel at front and slant view angles; dividing actual luminance values according to the area ratio of the main pixel area M and the sub pixel area S, and establishing corresponding relationships between the grayscale and the actual luminance values in the main and the sub pixel areas; calculating theoretical luminance values of each grayscale; setting a grayscale combination, such that a sum of difference values between actual and theoretical luminance values of the front and slant view angle are minimal; and repeating the last step to obtain grayscales respectively input to the main pixel and the sub pixel areas at all of grayscales of the liquid crystal panel. A liquid crystal display setting a grayscale value using the above method is also disclosed.
