ACTIVE 3D SHUTTER-GLASSES OFFERING AN IMPROVED LEVEL OF IMAGE-BRIGHTNESS

摘要

The present invention discloses the design of active 3d shutter-glasses for the viewing of time-multiplexed stereoscopic three dimensional (3d) images that offer both an improved level of on-screen image-brightness as well as reduced manufacturing costs as compared to other prior-art technologies. The disclosed invention is based on the insight that a tangential in-plane electrical- field can be utilized in order to provide for a voltage-assisted relaxation switching step together with cholesteric liquid crystal materials, thereby increasing the relaxation speed of said cholesteric liquid crystal materials thereof. Furthermore, dichroic-dye materials can additionally be added to said cholesteric liquid crystal materials in order to absorb at least some of the scattered light and hence reduce the overall level of perceived on-screen image-haze.
