Abstract

The invention discloses an anti-laser speckle projection curtain surface structure and a preparation method, relates to the technical field of projection curtains, and aims to solve the problems that the image quality of a conventional projection curtain is easily affected by light, so that the brightness is not uniform, the image quality is low, the anti-laser speckle effect cannot be achieved, and the watching requirements of audiences cannot be met. In order to overcome the defects in the prior art, the invention provides the following technical scheme that the anti-dazzling screen comprises a base material layer, a curtain layer is arranged on the upper surface of the base material layer, and an optical structure layer is arranged on the upper surface of the curtain layer. According to the anti-laser-speckle projection curtain surface structure and the preparation method, the brightness and contrast of an optical curtain can be improved, good laser speckle resistance can be achieved, the picture quality is improved, the projection curtain is not prone to being influenced by light rays, then the watching requirements of vast audiences can be met, good fireproof and damp-proof effects can be achieved, the projection screen is protected, and the service life of the projection screen can be prolonged.

Description

technical field [0001] The invention relates to the technical field of projection screens, in particular to a laser speckle-resistant projection screen surface structure and a preparation method. Background technique [0002] Projection screens are used in movies, offices, home theaters, and large conferences. They are tools for displaying images and video files. Projection screens are also called projection screens. They are generally divided into commercial screens, home screens, and engineering screens. The types of screens There are many, divided into high, medium and low grades, which can be determined according to the situation of the occasion. [0003] However, the image quality of the current projection screen is easily affected by the light, resulting in uneven brightness, low image quality, and cannot play the role of anti-laser speckle, which cannot meet the viewing needs of the audience. There is no corresponding solution for this defect. Improve. Contents of ...
