    • A display system is disclosed that includes a light source, an integrator rod receiving a light beam from the light source and producing an integrated light beam, a beam splitting device splitting the integrated light beam into at least a first cone of light and a second cone of light, the cones of light having complementary intensity distributions, and at least a first spatial light modulator and a second spatial light modulator, wherein the first spatial light modulator is capable of selectively reflecting portions of the first cone of light in an ON direction and the second spatial light modulator is capable of selectively reflecting portions of the second cone of light in an ON direction. The display system further includes a combining device for combining the selectively reflected portions of the cones of light in the ON direction and projection optics for projecting the combined reflected cones of light.
    • 公开了一种显示系统,其包括光源,接收来自光源的光束并产生集成光束的积分器杆,将所述集成光束分成至少第一光锥和第二锥体的分束装置 的光,具有互补强度分布的光的锥形,以及至少第一空间光调制器和第二空间光调制器,其中第一空间光调制器能够选择性地反射第一锥形光在ON方向上的部分, 第二空间光调制器能够选择性地反射第二光锥的部分在ON方向上。 该显示系统还包括一个组合装置,用于将ON方向上的锥形光纤的选择反射部分与用于投射组合的反射光锥的投影光学装置组合。
