Patent ID: 7224335

Claim:
A projection system comprising: (a) a first spatial light modulator (SLM) having a first array of separately addressable pixels, the first SLM adapted to receive light from a light source and to modulate light into a subsequent SLM; (b) a second SLM having a second array of separately addressable pixels, the second SLM positioned in series with the first SLM to receive modulated light from the first SLM and to direct that light for producing an output; and (c) a controller coupled to the first SLM for delivering first image data comprising first pulse width modulation data to the first SLM, and coupled to the second SLM, for delivering second image data comprising second pulse width modulation data to the second SLM, wherein the first pulse width modulation data is synchronized with the second pulse width modulation data and each bit duration and split bit duration of the second SLM corresponds to an available bit duration and split bit duration of the first SLM in order to produce a multiplicative effect of a bit time duration for all image intensities to provide a viewable image at said output.
