Patent ID: 8547314

Claim:
A liquid crystal display, comprising: a liquid crystal panel configured for displaying an image having a plurality of image elements, the liquid crystal panel comprising a plurality of pixel units each corresponding to one of the image elements; a gray scale correction circuit, comprising: a calculator configured to perform a predetermined calculation on an actual chroma coordinate value of a full-white image of the liquid crystal panel, boundary coordinate values of a chroma region in which the actual chroma coordinate value is located, and preset gray scale correction values of the boundary coordinate values to provide a corrected gray scale value; and an output unit configured to provide a corrected red, green, blue (RGB) data set according to the corrected gray scale value; and a control circuit, comprising: a data analyzer, configured for analyzing a gray scale value of the original RGB data signal set, comparing the analyzed gray scale value with a predetermined gray scale value, and thereby generating a control signal according to a comparison result; and a selector, configured to select one of the original RGB data set and the corrected RGB data set as the output RGB data set of the control circuit according to the control signal; and a data driver configured for providing a gray scale voltage to the liquid crystal panel according to the an output RGB data set of the control circuit.
