ABSTRACT:
A pixel of the LCD is driven according to a precharge pixel value and a compensation pixel value both being generated from a pixel value during a precharge field and a compensation field respectively. A precharge driving voltage corresponding to the precharge pixel value, and a compensation driving voltage corresponding to the compensation pixel value is then determined and used to drive the pixel. The lightness of the pixel driven according to the precharge pixel value and the compensation pixel value is substantially the same as the lightness of the pixel if driven according to the pixel value. The precharge field comes before the compensation field when the precharge pixel value is larger than the compensation pixel value, and the compensation field comes before the precharge field when the compensation pixel value is larger than the precharge pixel value.
