Abstract

The invention discloses a projection screen and a manufacturing method thereof, relates to the technical field of projection display, and is used for solving the problem that a Fresnel lens layer in the projection screen is easy to fall off from an attached surface. The projection screen comprises a reflecting layer, a Fresnel lens layer and a base material layer. The Fresnel lens layer and the reflecting layer are stacked, the base material layer is stacked on the side, away from the reflecting layer, of the Fresnel lens layer, and the surface of the side, close to the Fresnel lens layer, of the base material layer is attached to the surface of the side, away from the reflecting layer, of the Fresnel lens layer. Wherein the base material layer is made of polyethylene glycol terephthalate, and the Fresnel lens layer is made of acrylate and polyurethane. The projection screen is used for displaying images projected by the projector.

Description

technical field [0001] The present application relates to the technical field of projection display, and in particular, to a projection screen and a manufacturing method thereof. Background technique [0002] In the field of projection display technology, projectors are generally used with projection screens. The light emitted by the projector is projected onto the projection screen, and after being reflected by the projection screen, it reaches the eyes of the audience, and the audience can watch the image formed by the light on the surface of the projection screen. [0003] In order to improve the projection effect of the projection screen, the projection screen can choose a projection screen with a Fresnel lens layer. The Fresnel lens layer generally conforms to the surface of other structures in the projection screen. [0004] However, the adhesion between the Fresnel lens layer and the attached surface is low, and the Fresnel lens layer is easily detached from the att...
