  • Reflective liquid crystal display with improved contrast
    Patent number: 6636285
    Abstract: A display (200) includes a slanted fringe volume hologram (206) or other optical element that steers light that passes into and out of the display (200) so as to provide angular separation between unmodulated scattered light and modulated reflected light. As a result of the angular separation the effective contrast of the display (200) is improved. By placing the slanted fringe volume hologram (206) below a front polarizer of the display a further reduction in the amount of unmodulated scatter light is achieved. The slanted fringe volume hologram is preferably a hologram of a diffusive object (328), and consequently exhibits a degree of light diffusion that results in a viewing zone of an appreciable angular extent.
    Type: Grant
