Abstract
A projection screen includes a lens base having a front side, a rear side, and an array of bores that extend from the rear side to the front side. Each of the bores tapers in a direction from the rear side to the front side. The front side is formed with a plurality of windows, each of which is aligned and communicated with a respective one of the bores. Light that enters the bores from the rear side of the lens base is subjected to multiple total internal reflections as the light propagates along the bores prior to exiting the lens base at the windows.
