Patent ID: 8773613

Claim:
A liquid-crystal display with reduced speckling having a multilayered structure and comprising: a micromirror layer with a plurality of fully reflective micromirror elements arranged in matrix pattern formed by rows of micromirror elements; a lightguide layer comprising a net of optically transparent lightguides having holographic elements formed in or on the transparent lightguides and arranged in matrix pattern; a liquid-crystal layer having liquid-crystal elements arranged in matrix pattern; and a polarization analyzer; and at least one coherent light source of predetermined wavelength optically coupled with the lightguide layer for propagating the light through the lightguide to the holographic elements; the micromirror elements, holographic elements, and liquid-crystal elements being aligned and having substantially equal planar dimensions; each micromirror element comprising a nonmoveable element, a moveable micromirror, and driving means for independent movement of the moveable micromirror relative to the nonmoveable element, lightguide layer, liquid-crystal layer, and polarization analyzer.
