Abstract

The paper presents a new optical system used in an ultra-thin rear projector with 1500 mm diagonal size and 260 mm depth. A refractive-reflective optical system was developed to achieve a large projection angle of 136 degrees and a small optical distortion of 0.1%. The optics consist of a convex aspherical mirror and a refractive lens. In addition, a new Fresnel screen composed of hybrid blades of refractive-TIR (total internal reflection) elements has been developed to attain good uniformity of brightness and color within the image area.
