| Zusammenfassung: | 1. Field of the Invention
A field sequential dichroic light valve using ferro-electric liquid crystal components and multi-layer thin film broadband polarizing beam-splitting devices as an optical switch. The field sequential dichroic light valve has a fast time response and a memory function, as well as a switch frequency larger than 180 Hz and an optical transmittance larger than 90%. Accordingly, the field sequential dichroic light valve can effectively switch R, G, B-colored light beams in time sequence, and can be applied to a full-color projection display system. |
