  • Patent number: 5905483
    Abstract: The invention intends to provide a display control apparatus which can perform the flickerless display at a high precision without changing a construction of the electrodes or the like of a display apparatus even when a display speed in the high precision display of a liquid crystal display apparatus is insufficient for the flickerless display in the non-interlace drawing. The display control apparatus 50 has a VRAM and a partial rewrite display control section. Since a WS (host computer) 1 prevents a flicker of the display in the animation image display, for an object which is drawn at a high speed, when image data stored in the VRAM is partially rewritten by the non-interlace, the partial rewrite display control section adds data indicative of the display position of the portion rewritten by the WS 1 to the image data and sync signal of such a rewritten portion and, after that, supplies the image data to a liquid crystal display apparatus 3 at the timing synchronized with the display to the CRT.

  • Patent number: 5805149
    Abstract: A display device includes a display having a plurality of pixels and a signal processor for processing first image data, corresponding to a first number of pixels in the display, to display second image data corresponding to a second number of pixels which is less than the first number of pixels in the display. The signal processor includes thinning out circuitry for receiving a series of plural clock pulses synchronized with the first image data, and for outputting a series of thinned out clock pulses formed by thinning out the received clock pulses at a compression ratio, thereby compressing the first image data. The signal processor also includes circuitry for extending the compressed first image data in a ratio different from the inverse of the compression ratio in accordance with the first pixel number so that one pixel of the compressed first image data corresponds to two or more of the pixels of the display.
