Abstract

A processing method for an optical imaging structure, comprising the following steps: S1, setting up a plurality of opposite columns; S2, winding strip-shaped functional belts on the columns, so that the functional belts pass through the columns and are arranged on the between the opposite columns; S3, pouring liquid glue between the opposite columns to cover the top of the functional belt; S4, solidifying the liquid glue so that the functional belt is integrated with the solid colloid. Since the functional bands are wound around the columns, the arrangement of the functional bands can be adjusted by adjusting the arrangement of the columns at will, thereby realizing various functional structures. By adjusting the column, not only the distance between the functional belts can be adjusted, but also the inclination and twist of the functional belts can be adjusted, and the functional belts of each row and column can be individually adjusted to meet specific functional requirements. The processing method of the present invention can not only break through the limitation of product size by traditional processing methods, but also has very low requirements on molds and has strong versatility.

Description

【Technical field】

[0001] The invention relates to a manufacturing process, in particular to a processing method for an optical imaging structure. 【Background technique】

[0002] There are many kinds of projection screens on the market, including front projection and rear projection, flat projection and air projection. In order to realize different functions, the structure of the projection screen is also various. Generally speaking, in order to improve the effect of the projection screen, the interior of the projection screen is usually provided with a subtle functional structure, for example, CN2013106548797 "Anti-ambient Light Projection Screen", CN2017106206232 "An Optical Flat Panel Structure for Realizing Air Imaging".

[0003] Traditional projection screens are usually formed by a coating process. For example, the substrate layer is produced first, and then a mold is used to coat and print on the substrate layer to form a specific raised microstructure, and then Othe...
