Abstract
A liquid crystal display (LCD) driving apparatus and the method thereof is disclosed. The method receives a pixel and drives a pixel of the LCD according to the pixel value in a frame period, wherein the frame period is divided into a precharge field and a compensation field. Firstly, a precharge pixel value is decided according to the pixel and a reference value. A compensation pixel value is decided according to the precharge pixel. Next, a precharge driving voltage is determined according to the precharge pixel value. Afterwards, a compensation driving voltage is determined according to the compensation pixel value. Finally, the pixel is driven according to the precharge driving voltage and the compensation driving voltage respectively during the precharge field and the compensation field.
