Abstract
A system and method for addressing and synchronizing a spatial light modulator (SLM) device and a scrolling color recovery (SCR) illumination system. This method applies all the colors to a single SLM simultaneously and recaptures light rejected by the color filters. The recaptured light is reapplied to the color filters and, if passed by the color filter, directed to the SLM. The SCR concept requires multiple colors to be imaged on to an SLM array simultaneously. As the color bands scroll across the SLM, the data applied to elements of the SLM changes to remain appropriate for the color being received by that element. The data applied to the SLM elements may be loaded into the SLM by reset ground with each reset group load delayed by a skew time relative to the previous group.
