[0002] The shading and anti-peeping structures used for micro-injection blinds on the market usually include a substrate layer with a micro-groove structure on the substrate layer. During processing, the micro-grooves are usually filled with functional and not completely light-transmitting materials to achieve the shading and anti-peeping functions. When the micro-grooves are filled, non-light-transmitting materials will definitely remain on the surface of the transparent structure, which will directly affect its transparency and uniformity. Especially when making large-sized membrane materials, the accuracy of existing production equipment basically cannot achieve products with excellent effects in mass production. [Summary of the invention]

[0013] It also includes an imaging layer, which is arranged on the side of the substrate layer opposite to the microstructure layer. The imaging layer and the microstructure layer are respectively located on both sides of the substrate layer.

[0014] A transparent adhesive layer is arranged on the surface of the substrate layer opposite to the microstructure layer.

[0015] A transparent adhesive layer is arranged on the surface of the microstructure layer opposite to the substrate layer.

[0016] When or after the transparent liquid curing adhesive is cured and formed, its surface is subjected to anti-reflection treatment.

[0023] In step S1 , the microstructure layer is processed using a light-transmitting material; the microstructure convex strips formed in step S1 are light-transmitting.

[0024] In step S3, when the transparent liquid curing adhesive is filled between the microstructure convex strips, the transparent liquid curing adhesive covers the top of the microstructure convex strips.

[0025] The functional materials include dark-colored materials with light absorption, light-colored materials with reflection, and light-colored materials with light transmittance.

[0041] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0042] like Figures 1 to 13 As shown, the louver-type projection screen of the present invention comprises a substrate layer 1 and a microstructure layer 2 , and further, it may also comprise an imaging layer 5 or an adhesive layer 6 .

[0043] like Figures 1 to 13 As shown, the substrate layer 120 is made of a light-transmitting material that allows light to pass through, and the manufacturing materials thereof include but are not limited to PET material, PVC material, EVA material, PC material, PMMA material, TPU material, glass material, etc. The substrate layer 120 may be hard and non-retractable, or soft and retractable. In this embodiment, the substrate layer 120 is preferably made of PET, which is transparent and has good physical and mechanical properties. It is easy to restore its original shape after rolling up, so that the flatness of the louver grating type projection screen can be maintained, so that the louver grating type projection screen will not be deformed due to multiple rolling and unfolding, thereby improving the commercial use value of the louver grating type projection screen.

[0044] The thickness of the substrate layer 120 can be set as required. When the thickness is thin, the louver type projection screen is easy to roll up and becomes a soft screen; when the thickness is thick, the louver type projection screen cannot be rolled up and becomes a hard screen.

[0045] like Figures 1 to 13As shown, the microstructure layer 2 is compounded on one side surface of the substrate layer 120. The microstructure layer 2 is provided with a plurality of parallel and spaced microstructure ridges 21. The microstructure ridges 21 are in the shape of long strips, extending from one end of the substrate layer 1 to the other end of the substrate layer 1. According to the usage habits of the louver grating projection screen, the microstructure ridges 21 are arranged horizontally, in other words, the microstructure ridges 21 extend 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 ridges 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 inclined at a certain angle to the substrate layer 1, in other words, relative to the surface of the substrate layer 1, the first surface 211 and the second surface 212 are inclined surfaces. In some embodiments, the cross section of the microstructure ridges 21 is triangular, and one end of the first surface 211 and 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 ridge 21 is trapezoidal, such as an isosceles trapezoid or a non-isosceles trapezoid, and the first surface 211 and the second surface 212 are spaced at both ends, 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 ridge 21 is an irregular polygon. In this embodiment, as a preference, the cross section of the microstructure ridge 21 is an isosceles trapezoid.

[0046] The microstructure ridges 21 are translucent, allowing light to pass through. The microstructure layer 2 is translucent as a whole. In other words, the microstructure layer 2 is made of a translucent material as a whole. The shapes of the microstructure ridges 21 can be the same or different. In the present embodiment, it is preferred that the shapes of the microstructure ridges 21 are the same. The sizes of the microstructure ridges 21 can be the same or different. In the present embodiment, it is preferred that the sizes of the microstructure ridges 21 are consistent. The distances between the microstructure ridges 21 can be equal or unequal, and can be set specifically as needed. In the present embodiment, it is preferred that the microstructure ridges 21 are distributed at equal intervals.

[0047] The size of the microstructure ridges 21 and the distance between the microstructure ridges 21 can be adjusted according to the precision of the processing equipment, and can be set according to the needs. In this embodiment, the distance between the microstructure ridges 21 is 0.03-6 mm, and the thickness of the microstructure ridges 21 ranges from 0.01 to 5 mm.

[0048] The microstructure layer 2 is formed by UV coating on the surface of the substrate layer 1. During implementation, UV glue is coated on one side of the substrate layer 120, and then a mold whose shape matches the shape of the microstructure ridges 21 is used to emboss it, and then a UV lamp is used to cure it, so that the UV glue is cured and formed, and then demolding is performed, and the mold is removed, so that a microstructure layer 2 with microstructure ridges 21 can be formed on the surface of the substrate layer 1. The microstructure layer 2 made by this process is essentially formed by curing UV glue, which is formed on the surface of the substrate layer 120, and is not integrally formed with the substrate layer 120. It is as transparent as the substrate layer 120, but the materials constituting the two are different.

[0049] In order to realize the corresponding functions, a functional material coating 4 is provided on the surface of the microstructure ridges 21 .

[0050] In some embodiments, the functional material coating 4 is formed by coating a dark material with light absorption on the surface of the microstructure ridge 21. The dark material is opaque and is used to absorb ambient light, thereby making an anti-light louver grating projection screen that resists ambient light interference. The dark material includes but is not limited to black ink, black paint, black colloid, black powder or other dark materials, which can be coated on the surface of the microstructure ridge 21 by a spraying process. The functional material coating 4 can be provided on a partial surface of the microstructure ridge 21 or on the entire surface of the microstructure ridge 21. In this embodiment, it is preferred that the functional material coating 4 is provided on the first surface 211, the second surface 212, and the third surface of the microstructure ridge 21.

[0051] 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 convex strip 21, which is used for reflective imaging. The light-colored material includes but is not limited to reflective microbead materials, light-colored inks, light-colored paints, metallic coatings and other materials. The light-colored material can be coated on the surface of the microstructure convex strip 21 by a spraying process. The functional material coating 4 can be provided on a partial surface of the microstructure convex strip 21, or on the entire surface of the microstructure convex strip 21.

[0052] In some embodiments, the functional material coating 4 is formed by coating a light-transmissive light-colored material on the surface of the microstructure ridge 21, which is used for transmission imaging. The light-colored material includes, but is not limited to, light-colored ink, light-colored paint, and other materials. The light-colored material can be coated on the surface of the microstructure ridge 21 by a spraying process to form a translucent or transparent functional material coating 4. The functional material coating 4 can be provided on a partial surface of the microstructure ridge 21, or on the entire surface of the microstructure ridge 21.

[0053] After the functional material coating 4 is formed on the surface of the microstructure ridges 21, a transparent liquid curing glue is filled between the microstructure ridges 21. When the transparent liquid curing glue is cured and formed, a light-transmitting area 3 is formed between the microstructure ridges 21. The transparent liquid curing glue can be selected from transparent AB glue or UV glue. When different types of transparent liquid curing glue are selected, the curing process is also different. When AB glue is selected, it can be cured by itself after being stationary for a certain period of time. When UV glue is selected, it can be cured by ultraviolet light irradiation. When the transparent liquid curing glue is filled between the microstructure ridges 21, the filling amount of the liquid transparent curing glue should make the liquid transparent curing glue higher than the top of the microstructure ridges 21, so that it can cover the microstructure ridges 21 as a whole after curing and forming, so that the microstructure ridges 21 are contained in the cured transparent colloid, so as to play a certain protective role, avoid dust accumulation between the microstructure ridges 21, and avoid accidental scratches caused by the uneven surface of the microstructure layer 2.

[0054] When the transparent liquid curing glue is filled between the microstructure ridges 21, the glue can be poured with reference to the known process. In order to improve the anti-glare effect, the surface of the transparent liquid curing glue after curing can be made to have an anti-reflective effect through the known process. For example, after the transparent liquid curing glue is filled between the microstructure ridges 21, when the transparent liquid curing glue is cured and formed, the surface of the transparent liquid curing glue after curing has a certain roughness through direct embossing by a grinding roller, so as to play an anti-reflective role. Alternatively, after the transparent liquid curing glue is cured and formed, an anti-reflective treatment can be performed on the surface of the transparent colloid to increase the surface roughness of the transparent colloid, improve the diffuse reflection effect, and thus play an anti-glare effect.

[0055] After the transparent liquid curing glue is cured and formed, the substrate layer 1, the microstructure layer 2 and the curing glue are combined into one body, which has the basic structure of a louver-type projection screen. On this basis, an imaging layer 5 or a transparent adhesive layer 6 can be further compounded. In some embodiments, the imaging layer 5 can be compounded on the side surface of the substrate layer 1 opposite to the microstructure layer 2. In some embodiments, the imaging layer 5 can be compounded on the side surface of the microstructure layer 2 opposite to the substrate layer 1. In some embodiments, the adhesive layer 6 can be compounded on the side surface of the substrate layer 1 opposite to the microstructure layer 2.

[0056] In order to more clearly introduce the structure and principle of the louver type projection screen of the present invention, different embodiments are described below. For the convenience of description, the front and back sides involved in each embodiment are based on the position of the audience during projection. The side of the louver type projection screen facing the audience is the front side, and the side of the louver type projection screen facing away from the audience is the back side.

[0057] Embodiment 1:

[0058] like Figure 4 As shown, the louvered grating projection screen of this embodiment is a front projection screen, which includes an imaging layer 5, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2. The functional material coating 4 is formed by coating a dark material with light absorption on the surface of the microstructure ridges 21. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The imaging layer 5 is a reflective imaging layer 5.

[0059] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0060] When in use, the imaging layer 5 of the louver grating projection screen is the back side, and the microstructure layer 2 is the front side. The projection device 7 is arranged on the front side of the louver grating projection screen, that is, on the side facing the microstructure layer 2. The projection light of the projection device 7 passes through the light-transmitting area 3 between the microstructure ridges 21 and the substrate layer 1, and is reflected back to the audience direction by the imaging layer 5 to achieve a front projection effect. When the ambient light is incident from directly above the louver grating projection screen, most of the ambient light is incident on the surface of the microstructure ridges 21 and is absorbed by the functional material coating 4 on the microstructure ridges 21, thereby absorbing the ambient light and reducing the interference of the ambient light on the projection light, thereby improving the contrast of the louver grating projection screen and improving the display effect.

[0061] In this embodiment, the functional material coating 4 is used to absorb ambient light to reduce ambient light interference.

[0062] Example 2

[0063] like Figure 5 As shown, the louvered grating projection screen of this embodiment is a rear projection projection screen, which includes an imaging layer 5, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2. The functional material coating 4 is formed by coating a dark material with light absorption on the surface of the microstructure ridges 21. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The imaging layer 5 is a transmissive imaging layer 5.

[0064] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0065] When in use, the microstructure layer 2 of the louver grating projection screen is the front side, and the imaging layer 5 is the back side. The projection device 7 is arranged on the back side of the louver grating projection screen, that is, on the side facing the imaging layer 5. The projection light of the projection device 7 passes through the light-transmitting area 3 between the imaging layer 5, the substrate layer 1 and the microstructure ridges 21 and is transmitted to the direction of the audience to achieve a rear projection effect. When the ambient light is incident from the upper back of the louver grating projection screen, most of the ambient light is incident on the surface of the microstructure ridges 21 and is absorbed by the functional material coating 4 on the microstructure ridges 21, thereby absorbing the ambient light and reducing the interference of the ambient light on the projection light, thereby improving the contrast of the louver grating projection screen and improving the display effect.

[0066] In this embodiment, the functional material coating 4 is used to absorb ambient light to reduce ambient light interference.

[0067] Example 3

[0068] like Figure 6 , Figure 7 As shown, the louver type projection screen of this embodiment is a transparent projection screen, and the audience can watch both the projected content and the scene behind the louver type projection screen. The louver type projection screen of this embodiment can be a front projection ( Figure 6 ), or rear projection ( Figure 7 ), which comprises an adhesive layer 6, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2, and the functional material coating 4 is formed by coating a dark material with light absorption on the surface of the microstructure ridges 21. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The adhesive layer 6 is used to stick the entire louver-type projection screen on a flat surface such as glass or a wall for use.

[0069] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0070] When casting, Figure 6As shown, the louver grating projection screen is pasted on the glass through the adhesive layer 6, the microstructure layer 2 of the louver grating projection screen is the front side, the adhesive layer 6 is the back side, and the projection device 7 is arranged on the front side of the louver grating projection screen, that is, on the side facing the microstructure layer 2. The projection light of the projection device 7 passes through the light-transmitting area 3 between the microstructure ridges 21 and the substrate layer 1 and forms an image on the glass to achieve a front projection effect. At the same time, the audience can also see the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21. When the ambient light is incident from the top of the louver grating projection screen, most of the ambient light is incident on the surface of the microstructure ridges 21 and is absorbed by the functional material coating 4 on the microstructure ridges 21, thereby absorbing the ambient light and reducing the interference of the ambient light on the projection light, thereby improving the contrast of the louver grating projection screen and improving the display effect.

[0071] When rear projection is used, Figure 7 As shown, the louver grating projection screen is pasted on the glass through the adhesive layer 6, the microstructure layer 2 of the louver grating projection screen is the front side, the adhesive layer 6 is the back side, and the projection device 7 is arranged on the back side of the louver grating projection screen, that is, on the side facing the adhesive layer 6. The projection light of the projection device 7 is imaged on the glass to achieve the rear projection effect. At the same time, the audience can also see the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21. When the ambient light enters from the front and upper part of the louver grating projection screen, most of the ambient light enters the surface of the microstructure ridge 21 and is absorbed by the functional material coating 4 on the microstructure ridge 21, thereby absorbing the ambient light and reducing the interference of the ambient light on the projection light, thereby improving the contrast of the louver grating projection screen and improving the display effect.

[0072] In this embodiment, the functional material coating 4 is used to absorb ambient light to reduce ambient light interference.

[0073] Example 4

[0074] like Figure 8 As shown, the louver type projection screen of this embodiment is a transparent projection screen, and the audience can watch both the projected content and the scene behind the louver type projection screen. The louver type projection screen of this embodiment is a front projection screen, which includes an adhesive layer 6, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2, and 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. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The adhesive layer 6 is used to stick the entire louver type projection screen to a flat surface such as glass or a wall for use.

[0075] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0076] When in use, the louver grating projection screen is pasted on the glass through the adhesive layer 6, the adhesive layer 1 of the louver grating projection screen is the front side, and the microstructure layer 2 is the back side. The projection device 7 is arranged on the front side of the louver grating projection screen, that is, on the side facing the adhesive layer 6. The projection light of the projection device 7 passes through the glass and the substrate layer 1, and enters the microstructure ridges 21 of the microstructure layer 2. Since the microstructure ridges 21 are light-transmitting, and the functional material coating 4 on the surface of the microstructure ridges 21 has a reflective effect, the projection light is reflected multiple times in the microstructure ridges 21 and then emitted from the microstructure ridges 21 and emitted toward the audience, thereby achieving a front projection effect. At the same time, the audience can also see the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21.

[0077] In this embodiment, the functional material coating 4 on the microstructure convex strips 21 is used for reflective imaging, and serves as an imaging layer 5 .

[0078] Example 5

[0079] like Fig. 9 As shown, the louver type projection screen of this embodiment is a transparent projection screen, and the audience can watch both the projected content and the scene behind the louver type projection screen. The louver type projection screen of this embodiment is a rear projection projection screen, which includes an adhesive layer 6, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2. The functional material coating 4 is formed by coating a light-colored material on the surface of the microstructure ridges 21, and the functional material coating 4 can transmit light, and is translucent or transparent. A transparent liquid curing glue is filled between the microstructure ridges 21, which forms a light-transmitting area 3 between the microstructure ridges 21 after curing, and covers the top of the microstructure ridges 21. The adhesive layer 6 is used to stick the entire louver type projection screen to a flat surface such as glass or a wall for use.

[0080] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0081] When using, Fig. 9As shown, the louver grating projection screen is pasted on the glass through the adhesive layer 6. The adhesive layer 6 of the louver grating projection screen is the back side, and the microstructure layer 2 is the front side. The projection device 7 is arranged on the back side of the louver grating projection screen, that is, on the side facing the adhesive layer 6. The projection light of the projection device 7 passes through the glass and the substrate layer 1 and enters the microstructure ridges 21 of the microstructure layer 2. Since the microstructure ridges 21 are light-transmitting and the functional material coating 4 on the surface of the microstructure ridges 21 is light-transmitting, the projection light passes through the microstructure ridges 21 and the functional material coating 4 and is transmitted toward the audience, thereby achieving a rear projection effect. At the same time, the audience can also watch the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21.

[0082] In this embodiment, the functional material coating 4 on the microstructure convex strips 21 is used for transmission imaging, and serves as an imaging layer 5 .

[0083] Example 6

[0084] like Fig.10 As shown, the louvered grating projection screen of this embodiment is a rear projection projection screen, which includes an imaging layer 5, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2. 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. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The imaging layer 5 is a transmissive imaging layer 5.

[0085] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0086] When using, Fig.10 As shown, the imaging layer 5 of the louver grating type projection screen is the back side, and the microstructure layer 2 is the front side. The projection device 7 is arranged on the back side of the louver grating type projection screen, that is, on the side facing the imaging layer 5. The projection light emitted by the projection device 7 passes through the imaging layer 5, the light-transmitting area 3 between the substrate layer 1 and the microstructure ridges 21 and is transmitted to the audience direction to achieve a positive rear projection effect. When the angle of the projection light causes the incident light to be incident on the functional material coating 4, the functional material coating 4 reflects it and emits it toward the audience direction.

[0087] In this embodiment, the functional material coating 4 is used to reflect the projection light, and has the function of the imaging layer 5 .

[0088] Example 7

[0089] like Fig.11As shown, the louver type projection screen of this embodiment is a transparent projection screen, and the audience can watch both the projected content and the scene behind the louver type projection screen. The louver type projection screen of this embodiment can be either front projection or rear projection, and it includes an adhesive layer 6, a substrate layer 1, and a microstructure layer 2 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2, and 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. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The adhesive layer 6 is used to stick the entire louver type projection screen to a flat surface such as glass or a wall for use.

[0090] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0091] When casting, Fig.11 As shown, the louver grating type projection screen is attached to the glass through the adhesive layer 6, the microstructure layer 2 of the louver grating type projection screen is the front side, the substrate layer 1 is the back side, and the projection device 7 is arranged on the front side of the louver grating type projection screen, that is, facing the side of the microstructure layer 2. The projection light of the projection device 7 passes through the light-transmitting area 3 between the microstructure ridges 21 and is incident on the functional material coating 4 and is reflected by the functional material coating 4 and emitted toward the audience to achieve a front projection effect. At the same time, the audience can also see the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21.

[0092] When rear projection is used, Fig.12 As shown, the louver grating projection screen is attached to the glass through the adhesive layer 6, the microstructure layer 2 of the louver grating projection screen is the front side, the substrate layer 1 is the back side, and the projection device 7 is arranged on the back side of the louver grating projection screen, that is, on the side facing the substrate layer 1. The projection light of the projection device 7 passes through the substrate layer 1 and is incident on the functional material coating 4 and is reflected by the functional material coating 4 and emitted toward the audience to achieve the rear projection effect. At the same time, the audience can also see the scene behind the glass through the light-transmitting area 3 between the microstructure ridges 21.

[0093] In this embodiment, the functional material coating 4 is used to reflect light for imaging, and acts as an imaging layer 5 .

[0094] Example 8

[0095] like Fig.13As shown, the louvered grating projection screen of this embodiment is a rear projection projection screen, which includes a substrate layer 1, a microstructure layer 2 and an imaging layer 5 in sequence. A functional material coating 4 is provided on the surface of the microstructure ridges 21 of the microstructure layer 2, and the functional material coating 4 is formed by coating a dark material with light absorption on the surface of the microstructure ridges 21. A transparent liquid curing glue is filled between the microstructure ridges 21, and after curing, a light-transmitting area 3 is formed between the microstructure ridges 21, and the light-transmitting area 3 covers the top of the microstructure ridges 21. The imaging layer 5 is a transmissive imaging layer 5, which is compounded on the surface of the transparent liquid curing glue after curing.

[0096] The working mode and working principle of the shutter grating type projection screen of this embodiment are as follows:

[0097] When using, Fig.13 As shown, the imaging layer 5 of the louver grating type projection screen is located on the front side, and the substrate layer 1 is located on the back side. The projection device 7 is arranged on the back side of the louver grating type projection screen, that is, on the side facing the substrate layer 1. The projection light of the projection device 7 passes through the substrate layer 1, the light-transmitting area 3 between the microstructure ridges 21, and the imaging layer 5 and is transmitted to the direction of the audience to achieve a rear projection effect. When the ambient light is incident from the front and upper side of the louver grating type projection screen, most of the ambient light is incident on the surface of the microstructure ridges 21 and is absorbed by the functional material coating 4 on the microstructure ridges 21, thereby absorbing the ambient light and reducing the interference of the ambient light on the projection light, thereby improving the contrast of the louver grating type projection screen and improving the display effect.

[0098] In this embodiment, the functional material coating 4 is used to absorb ambient light to reduce ambient light interference.

[0099] In addition, the present invention also provides a method for processing a louver grating type projection screen, which comprises the following steps:

[0100] S1, a microstructure layer 2 is processed on the substrate layer 1 by UV coating process, and the microstructure layer 2 is provided with a plurality of parallel and spaced microstructure convex strips 21 (such as Figure 1 shown);

[0101] S2, coating the functional material on the surface of the microstructure convex strip 21 to form a functional material coating 4 (such as Figure 2 shown);

[0102] S3, filling transparent liquid curing glue between the micro-structure convex strips 21, and curing the transparent liquid curing glue into shape (such as Figure 3 shown);

[0103] In step S1, the microstructure layer 1 is processed using a light-transmitting material; the structure of the microstructure ridges 21 formed in step S1 is as described above (eg Figure 1As shown), no further description is given here.

[0104] In step S2, the functional material includes a dark-colored material with light absorption, a light-colored material with reflection, and a light-colored material with light transmittance.

[0105] After the functional material coating 4 is formed on the surface of the microstructure ridges 21, a transparent liquid curing glue is filled between the microstructure ridges 21. The transparent liquid curing glue can be selected from transparent AB glue or UV glue. When different types of transparent liquid curing glue are selected, the curing process is also different. When AB glue is selected, it can cure itself after being stationary for a certain period of time. When UV glue is selected, it can be cured by ultraviolet light irradiation. When the transparent liquid curing glue is filled between the microstructure ridges 21, the filling amount of the liquid transparent curing glue should make the liquid transparent curing glue higher than the top of the microstructure ridges 21, so that it can cover the microstructure ridges 21 as a whole after curing and forming, so that the microstructure ridges 21 are contained in the cured transparent colloid.

[0106] When the transparent liquid curing glue is filled between the microstructure ridges 21, the known process can be referred to for the glue filling. To improve the anti-glare effect, after the transparent liquid curing glue is cured and formed, the surface of the transparent colloid can be subjected to anti-reflective treatment to increase the surface roughness of the transparent colloid, improve the diffuse reflection effect, and thus achieve the anti-glare effect.

[0107] After the transparent liquid curing glue is cured and formed, the substrate layer 1, the microstructure layer 2 and the curing glue are combined into one body, which has the basic structure of a louver-type projection screen. On this basis, an imaging layer 5 or a transparent adhesive layer 6 can be further compounded on one side of the substrate layer 1 or the microstructure layer 2. The process of forming the imaging layer 5 or the adhesive layer 6 can refer to the known technology.

[0108] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
