Abstract
A rear-projection display system comprises a light engine, a beam-splitter that receives light from the light engine, a projection lens that receives an image from the beam-splitter, a rear-projection screen, and a mirror that receives the image from the projection lens and reflects it onto the screen. The beam-splitter has a reflecting element, receives an image, and reflects the image off the reflecting element at an angle of incidence that is substantially unequal to 45 degrees.
