  • Patent number: 4921334
    Abstract: The perceived gray scale brightness levels of a Matrix Addressed Liquid Crystal Display are increased over the number of levels provided by the existing data line driver hardware and the gray scale voltage increments by providing an extra command bit position. For time multiplexing the gray scale voltage increment on a pixel during successive frames. For an extra bit value of 0 the gray scale voltage is the same during alternate frames providing a given brightness level. For an extra command bit value of 1, the gray scale voltage increment applied to the pixel and the brightness level, is switched (dithered) between voltages during successive frames. The eye integrates the levels and the perceived gray scale brightness level is the average value of brightness thus, doubling the number of perceived gray scale levels.
