ABSTRACT:
A television display apparatus wherein a white light source emits a beam onto a plurality of dichroic mirrors which split the beam into three beams of the primary colors, then reflects the three primary beams onto three deformable reflective surfaces, which again reflect the beams through slits in a non-reflective surface, thereby modulating the intensity of the beams. The amount of light passing through the slits is horizontally scanned by one surface of a rotating polygonal mirror, then passes through collimating and projection lenses and onto a screen.
