We developed a new rear projection screen compriseding of two total internal reflecting prism sheets laminated to each other in a 90 degree angle. The advantages of this screen are not only wider vertical viewing angle, but improved black level, the uniformity of color temperature, reduced scintillation, and reduced ghost images.
