Patent ID: 7746307

Claim:
A liquid crystal display (LCD), comprising: a data driver; a plurality of data lines, electrically coupled to the data driver; a plurality of scan lines; a scan driver, for sequentially enabling the scan lines; and a plurality of display units, each comprising at least: a first sub-pixel, controlled by one of the scan lines and used for receiving a first positive data voltage or a first negative data voltage from one of the data lines to generate luminance corresponding to a first grey value or a second grey value; and a second sub-pixel, controlled by one of the scan lines, wherein the first sub-pixel and the second sub-pixel are not the same in area or shape, the second sub-pixel is used for receiving a second positive data voltage or a second negative data voltage from one of the data lines to generate luminance corresponding to a third grey value or a fourth grey value; wherein when the first to the fourth grey values are equal, an average value of the first positive data voltage and the first negative data voltage is not equal to an average value of the second positive data voltage and the second negative data voltage.
