Problems solved by technology

[0003] However, the anti-ambient light effect of the projection screen is relatively poor. When the projection screen reflects the light projected by the projector, it will also reflect the light of the ambient light, resulting in poor contrast of the projection screen and affecting the user's viewing experience.

Abstract

The invention discloses a projection screen and a manufacturing method thereof, relates to the technical field of projection display, improves the ambient light resistance of the projection screen, and improves the projection effect. The projection screen comprises a reflecting layer, a Fresnel lens layer, a surface layer and a light filtering layer. The Fresnel lens layer and the reflecting layer are stacked, the surface layer is stacked on the side, away from the reflecting layer, of the Fresnel lens layer, and the filter layer is stacked on the side, away from the Fresnel lens layer, of the surface layer. Wherein the light filtering layer comprises a first light filtering layer and a second light filtering layer. The second filter layer and the first filter layer are stacked, and the refractive index of the second filter layer is larger than that of the first filter layer. 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, in particular to a projection screen and a manufacturing method thereof. Background technique [0002] In the field of projection display technology, a projector is generally used with a projection screen. The light emitted by the projector is projected onto the projection screen, and reaches the eyes of the audience after being reflected by the projection screen, and the audience can watch the image formed by the light on the surface of the projection screen. [0003] However, the effect of the projection screen against ambient light is relatively poor. When the projection screen reflects the light projected by the projector, it also reflects the light of the ambient light, resulting in poor contrast of the projection screen and affecting the user's viewing experience. Contents of the invention [0004] The present application provides a projection screen and a manufactur...
