Abstract: A transparent projection screen and a manufacturing method. The transparent projection screen is for receiving projection light and transmitting ambient light and comprises a first substrate layer, a Fresnel structure layer, a surface diffusion layer, a nano metal plating layer, and a binding adhesive layer. The Fresnel structure layer is disposed on the first substrate layer and comprises a prism surface. The surface diffusion layer is disposed on a portion of the prism surface. The nano metal plating layer is disposed on the surface diffusion layer. The binding adhesive layer is disposed on the nano metal plating layer and fills and levels the prism surface. The projection light passes the first substrate layer and is incident on the prism surface and then reflected thereby. The ambient light passes the binding adhesive layer, the nano metal plating layer, the surface diffusion layer and the first substrate layer, and is emitted.

Abstract: A total reflection screen comprises a light diffusion layer, a total reflection layer and a light absorption layer arranged sequentially from an incidence side of the projected light. The light absorption layer can absorb an incident light. The light diffusion layer is used for increasing a divergence angle of emergent light. The total reflection layer comprises a plurality of microstructure units that is rotationally symmetrical and extends continuously in a plane of the total reflection screen. Each of the microstructure units comprises a first material layer disposed at the side of the light diffusion layer and a second material layer disposed at the side of the light absorption layer. The interface between the first material layer and the second material layer is comprised of two intersecting planes, which are disposed in such a way that the projected light is subjected to total reflection continuously at the two intersecting planes.
