US Patent 7471300 Progressive data delivery to spatial light modulators

In a spatial light modulator, a frame may be broken up into a plurality of colors. A given frame may include at least a first portion and a second portion. During the first portion of the frame, more significant bits of the data for a given pixel may be displayed and during a second portion of the frame, less significant bits may be disclosed. In some embodiments, the frame may be broken into two color subframes for each color, but in other embodiments, more than two such subframes may be utilized. In one embodiment, the frame may be broken into red, blue, and green and each color may be displayed at least twice, such that more significant bits are displayed first and less significant bits are displayed thereafter.
