  • Conversion of a video signal for driving a liquid crystal display
    Patent number: 6909472
    Abstract: Method and apparatus for the conversion or generation of a video signal intended to be displayed on an image display with different luminance response times for rise and fall. The conversion or generation of the video signal is so that motion artefacts which are caused by the difference in luminance response times for rise and fall such as large area luminance jumps, large-area flicker and faulty temporary large-area luminance are fundamentally cancelled in the displayed image.
    Type: Grant
    Filed: February 4, 2002
    Date of Patent: June 21, 2005
    Assignee: Barco N.V.
    Inventors: Koen Gadeyne, Patrick Vandenberghe

  • Conversion of a video signal for driving a liquid crystal display
    Patent number: 6359663
    Abstract: Method and apparatus for the conversion or generation of a video signal intended to be displayed on an image display with different luminance response times for rise and decay. The conversion or generation of the video signal is so that motion artifacts which are caused by the difference in luminance response times for rise and decay such as large area luminance jumps, large-area flicker and faulty temporary large-area luminance are fundamentally cancelled in the displayed image.
