Abstract:
1. A reflective display apparatus comprising: a first liquid crystal cell, said first liquid crystal cell comprising a plurality of first full-color pixel elements configured to produce full-color images, said first pixel elements being controllable between a non-reflective state, in which electromagnetic radiation having a first polarization is reflected to a first extent, and a reflective state, in which said electromagnetic radiation having a first polarization is reflected to a second extent, said second extent being greater than said first extent, wherein the first liquid crystal cell is further configured to reflect electromagnetic radiation of the first polarization according to a first perspective view of a full-color image in a first direction; and a second liquid crystal cell, said second liquid crystal cell comprising a plurality of second full-color pixel elements configured to produce full-color images, said second pixel elements being controllable between a non-reflective state, in which electromagnetic radiation having a second polarization is reflected to a third extent, and a reflective state, in which said electromagnetic radiation having a second polarization is reflected to a fourth extent, said fourth extent being greater than said third extent, wherein the second liquid crystal cell is further configured to reflect electromagnetic radiation of the second polarization according to a second perspective view of the full-color image in a second direction, the first perspective view being separate from the second perspective view, and the first direction being different from the second direction, further characterized in that said first and second liquid crystal cells are configured so that said first polarization is different from said second polarization.
