PROBLEM TO BE SOLVED: To provide a driving device and driving method for a liquid crystal display (LCD) of improved display quality. SOLUTION: The signal of a pixel is received and the pixel of the LCD is driven according to a pixel value during a frame period. The frame period is divided to a precharge field and a compensation field. Firstly, a precharge pixel value is determined according to the pixel and a reference value. Secondly, a precharge driving voltage is determined according to the precharge pixel value. Thence, 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.
