Abstract
A scanning projector display includes a light engine comprising N emitters coupled to a collimator for providing a fan of N light beams of variable optical power levels, where N>1. The N emitters are spaced apart from each other such that pixels of the image simultaneously energized by neighboring ones of the N emitters are non-adjacent. A scanner receives and angularly scans the fan of N light beams about first and second non-parallel axes to provide an image in angular domain. A controller coupled to the scanner and the light engine causes the scanner to simultaneously scan the fan of N light beams about the first and second axes, and cause the light engine to vary the optical power levels of the N emitters with time delays such that adjacent pixels of the image are energized by different ones of the N emitters.
