ABSTRACT:
A faceplate (10a) for directly viewing an image generated by a digital micromirror device (10b), which generates images by tilting tiny mirror elements (11) to on or off positions. The faceplate (10a) has a number of optical fibers (12) parallel to each other and closely spaced together. The ends of the optical fibers (12) are the top and bottom surfaces of the faceplate (10a). Both ends of each fiber (12) is sliced at an angle determined by the on position of the mirror elements (11). This permits light to travel down the fibers (12) and be reflected back to the viewer by only those mirror elements (11) that are on.
