Abstract

The invention discloses a naked eye 3D (three-dimensional) front-projection screen, a naked eye 3D rear-projection screen and a naked eye 3D projection system. The front-projection screen comprises a surface biconvex micro-cylindrical lens board and a diffuse reflection layer, wherein multiple rows of micro-cylindrical convex lenses are horizontally and tightly arrayed on two sides of the surfacebiconvex micro-cylindrical lens board; the micro-cylindrical convex lenses on the two sides of the surface biconvex micro-cylindrical lens board are same in quantity and are in one-to-one correspondence; the micro-cylindrical convex lenses are all in a vertical bar shape and are same in pitch; the pitches are positive integral multiples of the pixel width of an image projected onto the projectionscreen by a projector; the diffuse reflection layer is located on the rear focal plane of the surface biconvex micro-cylindrical lens board; and the principle of the rear-projection screen is as sameas that of the front-projection screen. Compared with the prior art, the screen and system provided by the invention have the beneficial effects of simple structure, easiness in processing and assembling and excellent three-dimensional display effect.
