  • Patent number: 6999052
    Abstract: A liquid crystal display (LCD) system, comprising a matrix of pixels, analyzes a video data stream for grayscale level jumps from extreme black to moderate gray levels. Transitions in grayscale levels are restricted between adjacent pixels so as to reduce image degradation due to fringe field effects. A memory, such as a plurality of shift registers, may be used to store grayscale levels of adjacent pixels which are compared and if a ratio between these grayscale levels exceeds a desire value then at least one of the grayscale levels is modified.
    Type: Grant

  • Patent number: 6972745
    Abstract: A liquid crystal display (LCD) system, comprising a matrix of pixels, analyzes a video data stream for grayscale level jumps from extreme black to moderate gray levels. Transitions in grayscale levels are restricted between adjacent pixels so as to reduce image degradation due to fringe field effects. A memory, such as a shift register, may be used to store and then grayscale levels to be written to adjacent pixels are compared and if a difference between these grayscale levels exceed a certain value then at least one of the grayscale levels is modified.

  • Publication number: 20030085856
    Abstract: A system and method for writing a video frame row by row in a liquid crystal display (LCD) having a matrix of liquid crystal pixels arranged in a plurality of columns and a plurality of rows is provided. The system and method are constructed and arranged to minimize image degradation in the LCD by charging the column capacitors to a mid gray voltage or some other common fixed voltage prior to writing each row. The fixed charge voltage may be achieved by coupling all of the column capacitors together and allowing them to equalize to an average voltage before each row is written. In a preferred embodiment, a successive column or group of columns is charged to the mid gray voltage while the preceding column is being charged to the desired video voltage and that sequence is repeated until each pixel in each row is written.
