Abstract
The present invention is directed to provide a driving circuit and driving method for a LCD having high performance of moving image displaying within few amount of memory and downscaled circuit. In the present invention, a voltage applied to a pixel to drive liquid crystal material in the pixel is determined as a voltage with which the transparency of the pixel at the end of the current field becomes the designated transparency. To determine the voltage, a data table for quick response in which output data is stored in correspondence with some of the possible value of a preceding field image data and some of the possible value of the current field image data is employed, and the output data corresponding to the preceding field image data and the current field image data is determined by the data table through linear interpolation. The voltage corresponding to the output data is applied to the pixel.
