Problems solved by technology

[0004] When the specific microstructure is processed by the coating process, the size of the microstructure has certain limitations, and the thickness of the light-shielding part is basically greater than 0.05mm, so that it will affect the light transmittance of the projection screen.
In addition, the existing technology cannot be used to process super-large projection screens, which has relatively large limitations in processing size

Embodiment 1

[0070] Such as Figure 1 to Figure 4 As shown, in step S1 , the uprights 10 include two rows of uprights 10 : a first row of uprights 11 and a second row of uprights 12 . A plurality of uprights 10 are respectively arranged in the first row of uprights 11 and the second row of uprights 12 . The first row of uprights 11 and the second row of uprights 12 are relatively spaced apart, and the distance between them is related to the size of the projection screen. The first row of columns 11 and the second row of columns 12 are used to set a functional belt 20, which can be used to process a large-scale optical imaging structure, that is, a projection screen or the basic structure of a projection screen, when the distance between them is relatively large. ; When the distance between them is small, it can be used to process small-sized optical imaging structures.

[0071] The number of uprights 10 in the first row of uprights 11 and the second row of uprights 12 can be set as requi...

Embodiment 2

[0110] Such as Figure 20 ~ Figure 22 As shown, the processing method for the optical imaging structure of this embodiment can be used to manufacture an air-imaging optical imaging structure.

[0111] Such as Figure 20 ~ Figure 22 As shown, in step S1 , the uprights 10 include four rows of uprights 10 : a first row of uprights 11 , a second row of uprights 12 , a third row of uprights 13 and a fourth row of uprights 14 . Several columns 10 are respectively arranged in the four rows of columns. The first row of uprights 11 and the second row of uprights 12 are relatively spaced apart, and the third row of uprights 13 and fourth row of uprights 14 are relatively spaced apart, and the distance between them is related to the size of the optical imaging structure. Between the first row of columns 11 and the second row of columns 12, between the third row of columns 13 and the fourth row of columns 14 are used to set functional belts 20, which can be used to process large-sized ...

Embodiment 3

[0139] Such as Figure 23 , Figure 24 As shown, the processing method of the optical imaging structure in this embodiment can be used to manufacture the optical imaging structure with the substrate 40 .

[0140] In step S1 , the columns 10 are disposed on two opposite sides of the substrate 40 . When operating, such as Figure 23 As shown, the substrate 40 is placed on the operating platform, and two rows of columns 10 are arranged on opposite sides of the substrate 40 : a first row of columns 11 and a second row of columns 12 . The first row of uprights 11 and the second row of uprights 12 can be arranged according to needs, which can refer to Example 1, which can be arranged perpendicular to the base material 40 or inclined to the base material 40 . The base material 40 can be made of known materials, for example, it can be glass, plastic sheet, plastic film and so on.

[0141] During specific implementation, the column 10 can be arranged on a mold, and the base materia...

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...
