Patent ID: 7205970

Claim:
A liquid crystal display for wide viewing angle, comprising: a timing controller for storing a plurality of sets of gray level correction values, each set of gray level correction values includes first and second gray level correction values corresponding to each gray level data and generating corrected gray level data in response to input gray level data, the corrected gray level data reflecting the gray level correction values corresponding to the input gray level data; a gate driver for outputting sequentially predetermined scanning signals; a data driver for receiving the corrected gray level data and transforming them into predetermined data voltages to be outputted; and a liquid crystal panel for displaying an image based on the data voltages when the scanning signals are inputted, wherein a lookup table stores the first and second grey level correction values produced by time-averaging brightness exhibited by more than two voltages using an inversion method or a method of optimizing a brightness pattern for each frame and thus brightness of the corrected gray level data is time-averaged with respect to the more than two voltages for each frame to be equal to brightness of the input gray level data.
