Abstract
A method for transmitting light in an image display system includes generating a beam of light from a light source. The beam of light is directed at a first segment of an electronically-switchable filter. A first portion of the beam of light is accepted by the first segment of the electronically-switchable filter, and a second portion of the beam of light is rejected by the first segment of the electronically-switchable filter. The first portion of the light beam is modulated to produce at least a portion of a displayed image. The second portion of the light beam is recycled to redirect the second portion of the light beam at a second segment of the electronically-switchable filter. The second portion of the light beam is accepted by the second segment of the electronically-switchable filter. The second portion of the light beam is modulated to produce at least a portion of the displayed image.
