In this embodiment, the substrate layer 120 is preferably made of a PET material, and is transparent, and has good physical and mechanical properties, and the substrate layer is easy to recover after being rolled, so that the flatness of the louver grating type projection screen can be maintained, the louver grating type projection screen is not deformed due to rolling and unfolding for many times, and the commercial use value of the louver grating type projection screen is further improved.

The thickness of the substrate layer 120 can be set as required, and when the thickness is thin, the shutter grating type projection screen is easy to be rolled into a soft screen; when the thickness of the shutter grating type projection screen is thicker, the shutter grating type projection screen can not be rolled and is a hard screen.

As shown in fig. 1 to 13, the microstructure layer 2 is compounded on one surface of the substrate layer 120. The microstructure layer 2 is provided with a plurality of microstructure convex strips 21 which are parallel and spaced. The microstructure convex strip 21 is in a long strip shape and extends from one end of the substrate layer 1 to the other end of the substrate layer 1. According to the habit of using the louver-type projection screen, the microstructure protrusion strip 21 is arranged horizontally, in other words, the microstructure protrusion strip 21 extends from one end of the substrate layer 1 to the other end of the substrate layer 1 along the horizontal direction. The shape of the microstructure protruding strips 21 can be set as required, and at least a first surface 211 and a second surface 212 are provided, and the first surface 211 and the second surface 212 are respectively inclined to the substrate layer 1 at a certain angle, in other words, the first surface 211 and the second surface 212 are inclined planes relative to the surface of the substrate layer 1. In some embodiments, the microstructure ribs 21 have a triangular cross section, and one end of the first surface 211 and one end of the second surface 212 are collinear, and the other end is parallel to the substrate layer 1. In some embodiments, the cross section of the microstructure protrusion strip 21 is trapezoidal, such as an isosceles trapezoid or a non-isosceles trapezoid, two ends of the first surface 211 and the second surface 212 are spaced apart, and a third surface is connected between the first surface 211 and the second surface 212, and the third surface is parallel to the substrate layer 1. In some embodiments, the cross section of the microstructure protrusion strip 21 is irregular polygon. In this embodiment, the cross section of the microstructure protrusion strip 21 is preferably an isosceles trapezoid.

The microstructure ribs 21 are light-transmitting, which allow light to pass through. The microstructure layer 2 is transparent, in other words, the microstructure layer 2 is made of transparent material. The shape of each microstructure ridge 21 may be the same or different, and in the present embodiment, it is preferable that the shape of each microstructure ridge 21 is the same. The sizes of the microstructure ridges 21 may be the same or different, and in the present embodiment, the sizes of the microstructure ridges 21 are preferably the same. The distances between the microstructure convex strips 21 may be equal or unequal, and may be specifically set according to the needs, and in this embodiment, the microstructure convex strips 21 are preferably distributed at equal intervals.

The size of the microstructure convex strips 21 and the distance between the microstructure convex strips 21 can be adjusted according to the precision of the processing equipment, and the microstructure convex strips can be specifically arranged according to the requirement. In this embodiment, the distance between the microstructure protruding strips 21 is 0.03-6 mm, and the thickness range of the microstructure protruding strips 21 is 0.01-5 mm.

The microstructure layer 2 is formed by UV coating on the surface of the base material layer 1. In implementation, a UV glue is coated on one surface of the substrate layer 120, then a mold with a shape matching with the shape of the microstructure convex strips 21 is used for imprinting the substrate layer, a UV lamp is used for curing the substrate layer, so that the UV glue is cured and molded, then the mold is removed, and the microstructure layer 2 with the microstructure convex strips 21 can be formed on the surface of the substrate layer 1. The microstructure layer 2 manufactured by using the process is essentially formed by curing the UV gel, is formed on the surface of the substrate layer 120, is not integrally molded with the substrate layer 120, is transparent as the substrate layer 120, and is made of a different material.

In order to realize the corresponding function, a functional material coating 4 is arranged on the surface of the microstructure convex strip 21.

In some embodiments, the functional material coating 4 is formed by coating a dark color material with a light absorption function on the surface of the microstructure convex strips 21, and is opaque to light, and is used for absorbing ambient light, so as to manufacture an anti-light shutter type projection screen with resistance to ambient light interference. The dark color material includes, but is not limited to, black ink, black paint, black colloid, black powder, or other dark color material, and may be coated on the surface of the microstructure ridges 21 by a spraying process. The functional material coating 4 may be provided on a partial surface of the microstructure ridges 21, or may be provided on the entire surface of the microstructure ridges 21. In this embodiment, the functional material coating 4 is preferably disposed on each of the first surface 211, the second surface 212, and the third surface of the microstructure ridge 21.

In some embodiments, the functional material coating 4 is formed by coating a light-colored material with a reflective effect on the surface of the microstructure ridges 21, and is used for reflective imaging. The light-colored material includes, but is not limited to, light-reflecting microbead material, light-colored ink, light-colored paint, metal coating and the like. The light color material can be coated on the surface of the microstructure convex strips 21 through a spraying process. The functional material coating 4 may be provided on a partial surface of the microstructure ridges 21, or may be provided on the entire surface of the microstructure ridges 21.

In some embodiments, the functional material coating 4 is formed by coating a light-transmissive material on the surface of the microstructure ridges 21, which is used for transmission imaging. The light-colored material includes, but is not limited to, light-colored inks, light-colored paints, and the like. The light color material can be coated on the surface of the microstructure convex strips 21 through a spraying process to form a semitransparent or transparent functional material coating 4. The functional material coating 4 may be provided on a partial surface of the microstructure ridges 21, or may be provided on the entire surface of the microstructure ridges 21.

After the functional material coating 4 is formed on the surface of the microstructure convex strips 21, transparent liquid curing glue is filled between the microstructure convex strips 21, and after the transparent liquid curing glue is cured and formed, light transmission areas 3 are formed between the microstructure convex strips 21. The transparent liquid curing glue can be transparent AB glue or UV glue. When different types of transparent liquid curing glue are selected, the curing process is different. When AB glue is selected, the AB glue can be cured by itself after standing for a certain time. When UV glue is selected, the curing can be carried out by ultraviolet irradiation. When the transparent liquid curing adhesive is filled between the microstructure convex strips 21, the filling amount of the liquid transparent curing adhesive is higher than the top of the microstructure convex strips 21, so that the liquid transparent curing adhesive can wholly cover the microstructure convex strips 21 after being cured and formed, the microstructure convex strips 21 are contained in the cured transparent adhesive, a certain protection effect can be achieved, dust accumulation between the microstructure convex strips 21 is avoided, and accidental scratching caused by the rugged surface of the microstructure layer 2 can be avoided.

When the transparent liquid curing adhesive is filled between the microstructure convex strips 21, the adhesive can be poured by referring to a known process. For example, after the transparent liquid curing adhesive is filled between the micro-structure convex strips 21, when the transparent liquid curing adhesive is cured and molded, the surface of the cured transparent liquid curing adhesive has certain roughness through direct imprinting of a grinding roller, so that the anti-reflection effect is achieved. Or after the transparent liquid curing adhesive is cured and molded, anti-reflection treatment can be performed on the surface of the transparent adhesive, so that the surface roughness of the transparent adhesive is increased, the diffuse reflection effect is improved, and the anti-glare effect is further achieved.

When transparent liquid curing glue solidification shaping back, substrate layer 1, micro-structure layer 2 and solidification colloid just combine into an organic whole, and it possesses the basic structure of shutter grating type projection screen. On the basis, an imaging layer 5 or a transparent adhesive layer 6 can be further compounded. In some embodiments, an imaging layer 5 may be compounded on the surface of the substrate layer 1 opposite the microstructured layer 2. In some embodiments, an imaging layer 5 may be compounded on the surface of the microstructure layer 2 opposite the substrate layer 1. In some embodiments, an adhesive layer 6 may be compounded on the surface of the substrate layer 1 opposite to the microstructure layer 2.

For convenience of description, the front and back surfaces in the embodiments are based on the position of the audience during projection, the side of the louver grating type projection screen facing the audience is the front surface, and the side of the louver grating type projection screen opposite to the audience is the back surface.

When the ambient light is emitted from the right above the louver grating type projection screen, most of the ambient light is emitted to the surface of the microstructure convex strips 21 and is absorbed by the functional material coating 4 on the microstructure convex strips 21, so that the effect of absorbing the ambient light is achieved, the interference of the ambient light to the projection light is reduced, the contrast of the louver grating type projection screen can be improved, and the display effect is improved.
