    摘要: A projection display may be formed by an imager which creates a portion of each of a plurality of spatially separated segments which together make up an overall image. The imager may produce one of those segments at any given instant of time. That segment is then replicated to fill each of the segments that form the overall image area. However, the segments that correspond to locations where that image portion should not exist are filtered out so that only one image portion for the correct segment is displayed. Each of the other segments may be produced in a time sequential fashion so that sequentially the segments fill the entire image. Thus, using this technique, substantially higher resolution may be achieved from a projection display system using fewer number of pixels in the microdisplay, in some embodiments.
