Abstract

The invention discloses a functional layer coating for a projection screen. The coating is prepared from the following components in parts by weight: 50-55 parts of aqueous styrene-acrylic emulsion, 12-20 parts of noble metal nanoparticles, 10-18 parts of ceramic powder, 3-6 parts of a plasticizer and 2-5 parts of a stiffening agent. The projection screen comprises a base layer as well as a glassfiber layer, a protective layer and a functional layer which are arranged on one side of the base layer sequentially. The projection screen has high optical efficiency, high screen brightness, 1.04 brightness gain and wide viewing angle range. Besides, the projection screen is provided with the protective layer for blocking water vapor, and can be prevented from damage caused by moisture.

Description

technical field [0001] The application belongs to the projection field, and in particular relates to a functional layer coating for a projection screen, a projection screen and a manufacturing method thereof. Background technique [0002] The projection screen is one of the most commonly used products in the peripheral equipment of the projector. When watching movies in the home theater or presenting materials in meetings and large-scale events, the projector is often used to project images onto a projection screen to make the image to be presented Completely and clearly presented on the white projection screen. Existing projection screens have problems such as unclear projected content, uneven brightness of projected content, and low brightness gain, which cannot satisfy the audience's desire for intuitive quality effects. [0003] After the light projected by the projector passes through the projection screen, due to the influence of the diffusion angle, the observer perc...
