|20080225236||Polarization conversion systems for stereoscopic projection - A polarization conversion system (PCS) is located in the output light path of a projector. The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.||09-18-2008|
|20080198456||Laminated retarder stack - Chemically-bonded retarder stacks are provided in this disclosure. A first organic layer having a first molecular orientation is chemically welded to a second organic layer having a second molecular orientation. The first and second molecular orientations are crossed when the organic layers are laminated. The first and second organic layers may be polycarbonate films, which can be welded together using a suitable solvent.||08-21-2008|
