| 摘 要： | 介绍一种以LED作为光源的单片LCOS全彩色投影机。证实由于偏振光转换导致的光输出限制是可以克服的，就是通过LCOS面板小的工作F#和LED与偏振光回收兼容性设计，而且避免了光源光束扩展量的增加。介绍LCOS投影HDTV在光收集元件和驱动方式等方面关键技术的进展。实例采用常规LED，得到大于401m的屏幕流明光通量。

| Abstract: | We report a full color projection display based on a single LCOS panel using LED light sources, We have demonstrated that light output limitation due to polarization conversion can be substantially overcome by the small working F/# of the LCOS panel and LED compatibility with polarization recycling without increasing source etendue. We are presenting key technology developments in light collection optics and driving strategies for an LCOS based projection HDTV, Our demonstrator with currently available LEDs produces more than 40 screen lumens. |
