A projection-type color image display system uses a reflective liquid crystal (LC) light modulator (24) and a polarizing beam-splitter (22) for separating the incoming and reflected light. Light from the source arrives on a first axis (28) and is reflected outward, with the imposed image, along a second...http://www.google.es/patents/US6563551?utm_source=gb-gplus-sharePatente US6563551 - High contrast polarizing optics for a color electro-optic display device
