ABSTRACT:
There is provided a motion-adaptive grayscale level converter section between a video signal source and a pixel array. The pixel array includes a liquid crystal cell of normally black and vertically aligned mode. The motion-adaptive grayscale level converter section determines based on information from a decoder section whether the pixels of an image represented by a video signal is in a moving image area. If a pixel is in a moving image area, the motion-adaptive grayscale level converter section changes the grayscale level data representing the grayscale level of the pixel so that there is no darker grayscale level than a predetermined first grayscale level. The resultant data is output as a video signal. Accordingly, we can provide a liquid crystal display capable of easing image quality degradation due to insufficient response when displaying a moving image while maintaining the contrast ratio achieved for a still image display.
