发明名称 OFF-AXIS IMAGE PROJECTION DISPLAY SYSTEM
摘要 An image projection display system is provided which utilizes an off-axis illumination configuration. A beam splitter is configured to direct a first light beam along a first optical path toward reflective imaging devices adapted to direct a second light beam along a second optical path to produce an image to be projected. Polarizing devices are interposed between the beam splitter and each imaging device, with the polarizing devices configured to allow passage of a first polarized component of the light beam while blocking passage of a second polarized component of the light beam. The display system provides a high contrast ratio and degree of brightness which significantly improves the final image quality projected to a display screen.
