Abstract
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.
Claims4
A projector screen comprising:
- a Fresnel lens for collimating incident light from a projection lens equipped in a light projection apparatus;
- a lenticular lens system comprising a plurality of constituent lenses, extending in parallel with respect to one another, for forming and spreading an image from the collimating light by said Fresnel lens;
- and
- a screen protection panel disposed adjacent said lenticular lens system,
- wherein said screen protection panel is equipped with a light-absorbing means for absorbing light spread by said lenticular lens system, and
- further comprising a projecting part formed at a predetermined height on the side of said screen protection panel that faces said lenticular lens system, and wherein said light absorbing means comprises a darkened stripe formed on said projecting part.
