Projector screen having an improved horizontal view angle |
摘要 |
A projector screen is composed of a Fresnel lens for collimating incident light from a light projection device, a lenticular lens formed of a plurality of constituent lenses for forming and spreading an image from the parallel light, and a screen protection panel for protecting a screen set up adjacent to the lenticular lens. A projecting part of a predetermined height is formed on the rear side of the screen panel facing the lenticular lens, and on the tip of the projecting part a black stripe is formed to serve as a light-absorbing means. The height of the projecting part is lower than that of a convex surface of the lenticular lens. The widened range of light-spreading angle of the lenticular lens improves a horizontal viewing angle.
