A novel LED-based illumination optics and color management system, Z cube, has been proposed for improving the primary saturation, uniformity and contrast of LCoS projector engines. In this paper, the working concept of the light engine is described and the optical performance has been evaluated with the simulation using ray tracing program, which shows a good uniformity for projector application.
