Lighting optics for LCD projector systems

摘要

The illumination optical apparatus of the LCD projector system has a Gaussian distribution of the incident light and half of the incident light having arbitrary polarized light is split in half and the other half is transmitted in the opposite direction, A liquid crystal display device comprising: a light source unit including a lamp and a reflector, wherein the light source unit includes a lamp and a reflector, A first and a second ultraviolet shielding mirror and a first and a second illumination light shielding unit configured to sequentially and vertically and horizontally sequentially transmit the amounts of visible light transmitted through the heat absorbing / , The second illumination optical section is constituted.
