Abstract
The present invention relates to a device and a method for controlling a liquid crystal display. The device comprises a luminance weighting value processor, an overdrive value generator, and an outputting unit. The luminance weighting value processor generates a weighting value according to a luminance value of a current pixel of a current frame of a video signal and a luminance value of a previous pixel of a previous frame of the video signal. The overdrive value generator generates an overdrive value according to a current pixel value of the current pixel and a previous pixel value of the previous pixel. The outputting unit generates an output pixel value according to the weighting value, the overdrive value and the current pixel value. Using the device and the method for driving a liquid crystal display according to the present invention, noise due to overdrive process can be reduced.
