ABSTRACT:
A projection display system includes a projection lens assembly that has multiple projection lens elements that are configured to receive light imparted with display information by a pixelated display device. The projection lens elements project the light toward a display screen. A pixel-shifting element is included within the projection lens assembly to cyclically shift between at least two positions within the projection lens assembly to form at a display screen at least two interlaced arrays of pixels. An electro-mechanical transducer is coupled to the pixel-shifting element to impart on it the cyclic shifting between positions.
