ABSTRACT:
A display system includes a display panel having an array of pixels, the pixels having ON states and OFF states. The pixels form images by modulating light in a temporal sequence during an image frame in response to drive signals generated from incoming video data. A light source arrangement that emits at least two colors of light illuminates the display panel. The image frame is divided into color segments with only one color of light being emitted from the light source during each segment. The color segments are further divided into grayscale periods. Transition segments are provided for the transitions between colors. The state of each pixel during these transition segments is a function of the desired brightness level for each pixel, as derived from incoming video data.
