Abstract:
     To obtain a high quality moving image display. The display control circuit CRL is provided with frame memories, a clock synthesizer, to double the input clock frequency, and a comparator circuit. The input display data, processed in a input processing circuit IDP, are stored in one of the frame memories as the first image data, and the other image data are stored to input next in the other frame memory as the second image data. The stored first image data are read out with the double speed clock signals as the image of the first field and supplied to each drain driver. The comparator circuit compares the second image data and the first image data stored in the frame memories for every pixel, and controls the output data processing circuit using this comparison result. It supplies dark display data as the display data for the second field, when the second image data are darker than the first image data, but supplies white display data when the second image data is brighter than the first image data.
