First Claim
Patent Images

1. A display, comprising:

  • a display panel, the panel having a plurality of pixels configured to modulate light in a temporal sequence so as to form an image during a frame, the pixels having a plurality of light modulating states, including OFF and ON;

    a light source arrangement that illuminates the display panel, the light source arrangement being configured to selectively emit light of at least one of at least two differing colors; and

    a data ordering arrangement that is receptive of incoming video data and that generates drive signals that drive the pixels to the light modulating states;

    wherein the frame is divided time-wise into color segments with only one of the different colors of light being emitted from the light source arrangement during each color segment, wherein the color segments include one or more grayscale periods, wherein the incoming video data includes information from which the data ordering arrangement determines pixel brightness values for each color segment, wherein the state of a pixel during each grayscale period is determined by the pixel brightness values for the corresponding color segment, and wherein pixels with pixel brightness values above predetermined values for each segment in a given frame are in a state other than OFF during corresponding grayscale periods of each color segment of the frame.
