Abstract
A high-resolution image is generated using multiple spatially offset lower-resolution digital micro-mirror device (DMD) panels. Multiple lower-resolution subframe signals for controlling the spatial light modulators are generated from a high-resolution image signal using a resolution reduction and interpolation algorithm. The spatial light modulators under control of the subframe signals are illuminated by a light source and light beams reflected from the spatial light modulators are combined and directed onto a screen for display.
