  • Liquid crystal display control circuit that performs drive compensation for high- speed response
    Publication number: 20020140652
    Abstract: Since the drive data for display or their correction values are stored in correspondence with the combination of the upper bits of the current frame image data and the upper bits of the previous frame image data, the capacity of the high-speed memory circuit that stores the conversion table can be reduced. Accompanying the reduction in the capacity of the conversion table, since the precision of the display drive data or their correction values becomes lower, an interpolation circuit is provided and, by means of an interpolation calculation the display, drive data or their correction values having increased precision is generated and consequently the input image data is corrected to generate the display drive data.
