REFLECTIVE STEREOSCOPIC DISPLAY

摘要

An apparatus comprising a first cell (10b), said first cell comprising a plurality of first elements (34b), said first 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. Said apparatus further comprises a second cell (10a), superimposed on the first cell, said second cell comprising a plurality of second elements (34a), said second 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. Said first and second elements are arranged so that said first polarization is different from said second polarization. The apparatus can be used in a reflective stereoscopic display.
