Patent ID: 7457036

Claim:
A projection screen comprising: a substrate; a reflective layer on the substrate; and a refractive layer on the substrate, the refractive layer comprising an array of anamorphic microlenses; wherein the projection screen has a front and a back and wherein the reflective layer and the refractive layer are arranged on the substrate such that light that is projected to the front of the projection screen passes through and is refracted by the refractive layer to impinge on the reflective layer and is reflected from the reflective layer back through the refractive layer to emerge from the front of the projection screen; and wherein the projection screen has a vertical axis and a horizontal axis and wherein the reflective layer and/or the refractive layer are configured to produce a vertical half angle of the light that emerges from the front of the projection screen that is less than a horizontal half angle of the light that emerges from the front of the projection screen.
