ABSTRACT:
A method of reducing artifacts in SLM-based display systems (10, 20), whose images are based on data displayed by bit-weight for pulse-width modulated intensity levels. The method can be used with a multiple spatial light modulators SLM system (20), which concurrently displays images of different colors, or with a single SLM system (10), which generates differently colored images sequentially during each frame period. For a multiple SLM system (20), the method is used with SLMs (14) that are memory-multiplexed, having "reset groups" that are loaded and displayed at different times. Corresponding rows of the SLM(s)s are associated with different reset groups.
