Abstract
A scanning projector display includes a plurality of light engines coupled to a MEMS scanner. Each light engine includes a light source subassembly for providing a diverging light beam optically coupled to a collimator for collimating the diverging light beam. In operation, the collimated light beams of the plurality of light engines impinge onto the tiltable reflector at different angles of incidence. A controller may be operably coupled to the light source subassembly of each light engine of the plurality of light engines and the MEMS scanner for tilting the tiltable reflector of the MEMS scanner. The controller is configured to energize the light source of each light engine in coordination with tilting the tiltable reflector for displaying the image.
