Screen and multiple-screen system
First Claim
1. A screen comprising:
- an angle magnifying unit comprising a first lens module and a second lens module, the first lens module and the second lens module aligned along a first direction, the first lens module comprising a plurality of first lenses, each of the first lenses comprising a first radius of curvature, the second lens module comprising a plurality of second lens, each of the second lenses comprising a second radius of curvature, the magnification of the angle magnifying unit is a ratio of the first radius of curvature to the second radius of curvature;
a first deflecting unit disposed between the first lens module and the second lens module, the first deflecting unit comprising a plurality of first deflecting prisms, the first deflecting prisms aligned along a second direction, wherein the first direction is perpendicular to the second direction; and
a second deflecting unit disposed at one side of the angle magnifying unit, the second deflecting unit comprising a plurality of deflecting prisms, and the second deflecting prisms aligned along a third direction, wherein the third direction is perpendicular to the first direction and the second direction.

Abstract
A screen is disclosed. The screen includes an angle magnifying unit and a deflecting unit. The angle magnifying unit has a first lens assembly and a second lens assembly. The first and second lens assemblies are aligned along a first direction. The first lens assembly has a plurality of first lenses, and each of the first lenses has a first radius of curvature. The second lens assembly has a plurality of second lenses, and each of the second lenses has a second radius of curvature. The magnification of the angle enlarging unit is the ratio of the first radius of curvature to the second radius of curvature. Furthermore, the deflecting unit is disposed between the first lens assembly and the second lens assembly. The deflecting unit has a plurality of deflecting prisms that aligned along a second direction. The second direction is perpendicular to the first direction.
