Lenticular lens sheet for projection screen

摘要

A lenticular screen component of a rear projection display screen has lenticular elements formed on a viewer surface. Identical lenticular elements cover the entire lenticular screen component and are repeated horizontally at a constant displacement. A given lenticular element includes a pair of reflective side portions and a refractive tip portion interposed between the side portions. One of the pair of side portions forms a sloped region at a joint between the one side portion and a side portion of an adjacent lenticular element. The sloped region is at an angle in a range between 5 and 15 degrees with respect to the first axis. The one side portion is covered with a reflective coating in at least a region of the one side portion that includes the joint. The pair of reflective side portions reflects light rays incoming from a projector towards the refractive tip portion for refracting the reflected light rays via a surface of the refractive tip portion facing a viewer. Each refracted light ray is refracted by a convex surface of the refractive tip portion.
