Abstract

An apparatus, system, and method for a front-projection screen having a subsurface diffusion target are disclosed herein.

Claims

1. A method of forming a front-projection screen comprising:

forming a refractive element on a first surface of a first layer;

coupling a first surface of a reflective diffusion target to a location on a second surface of the first layer to receive radiation incident upon the refractive element within a first range of angles;

coupling a first surface of a transparent substrate to the second surface of the first layer and to a second surface of the reflective diffusion target; and

coupling an absorption layer to a second surface of the transparent substrate.

2. The method of forming the front-projection screen of claim 1, wherein the coupling of the reflective diffusion target further comprises:

printing the diffusion target on the second surface of the first layer.
