Abstract
A sequential color display system (10) suited to receive data (20) at different rates without discarding or filtering video data. The mismatch of bandwidths between the input source video data and the output sequential color display is accommodated by retaining a modified synchronous operation. A color wheel (50) having a plurality of segments is utilized whereby the input frame rate in reference to the color wheel rate is always a ratio of integers. Using a digital micromirror device (44) spatial light modulator, no mixing of frame-to-frame bit planes is required during a colored segment. In the preferred embodiment, the ratio of integers is 7-to-6 for a 50 hertz input, such as a system, or a 5-to-6 ratio for a 72 hertz input. The color wheel is maintained at about a 60 hertz rate.
