As shown in fig. 1, the short-focus positive projection type soft curtain of the present invention comprises an anti-glare layer 1, a transparent substrate layer 2, a transparent functional layer 3, a black ink layer 4, and a flexible substrate layer 5 in sequence.
As shown in fig. 1, the anti-glare layer 1 is used to improve the scattering of light, and prevent the light from exiting in a single direction, so as to achieve the purpose of anti-glare. The anti-glare layer 1 is transparent, and the outermost surface of the anti-glare layer has certain roughness, so that the diffuse reflection of light can be enhanced. The inner side surface of the anti-glare layer 1 is a smooth flat surface and is used for being compounded with the transparent substrate layer 2. The antiglare layer 1 may be a known antiglare layer 1.
As shown in fig. 1, the transparent substrate layer 2 is transparent and allows light to pass through. The transparent substrate layer 2 is compounded on the inner side surface of the anti-glare layer 1. The transparent substrate layer 2 is made of a material including but not limited to a PET material, a PVC material, an EVA material, a PC material, a PMMA material, a TPU material and the like. The transparent substrate layer 2 is thin and has certain flexibility and can be bent and rolled.
As shown in fig. 1, the transparent functional layer 3 is compounded on the transparent substrate layer 2. The transparent functional layer 3 is made of a transparent material, such as a PET material, a PVC material, an EVA material, a PC material, a PMMA material, a TPU material, and the like. The transparent functional layer 3 is provided with a plurality of strip-shaped unit grooves 31. The unit groove 31 is a hollow groove recessed in one side surface of the transparent functional layer 3. The opening of the unit groove 31 faces away from the transparent substrate layer 2 and toward the flexible substrate layer 5.
As shown in fig. 1, the unit groove 31 extends from one end of the transparent functional layer 3 to the other end thereof in a transverse direction. Two adjacent unit grooves 31 are spaced in parallel. The unit grooves 31 are uniform in size and are uniformly arranged.
As shown in fig. 1, the unit cell 31 has a right-angled triangle cross-section. The unit cell 31 is provided with a first inner wall 311 and a second inner wall 312. The first inner wall 311 and the second inner wall 312 are adjacent to each other, and an angle therebetween is an acute angle. The first inner wall 311 is perpendicular to the transparent substrate layer 2 and the flexible substrate layer 5. The second inner wall 312 is inclined to the transparent substrate layer 2 and the flexible substrate layer 5. The inclination angle of the second inner wall 312 can be set according to the attribute of the short-focus projection device 8, and when the angle between the second inner wall 312 and the first inner wall 311 is smaller, the focal length of the projection device 8 is shorter, and the setting position of the projection device 8 is closer to the projection screen.
As shown in fig. 1, a light absorbing material 6 is disposed on the first inner wall 311. The light absorbing material 6 is used to absorb ambient light to reduce ambient light interference. The light absorbing material 6 includes, but is not limited to, black ink, black paint, black colloid, black powder, or other dark colored material. In this embodiment, the light absorbing material 6 is black ink, and is coated on the first inner wall 311 by a known coating process.

The light reflecting material 7 can be selected according to the known technology, and materials with reflecting function can be selected as the light reflecting material 7, such as light bead materials, light color ink, metal paint, and the like. In this embodiment, the light reflective material 7 is a silver gray metal coating, which is coated on the second inner wall 312 by a known process. When the light reflecting material 7 is coated on the second inner wall 312, it forms a thin silver gray opaque layer on the second inner wall 312.
It should be noted that the light absorbing material 6 and the light reflecting material 7 are relative terms, and the light absorbing material 6 means that the material has a far greater absorption capacity than the material has a reflection capacity for light, for example, a dark material generally has a far greater absorption capacity than the material has a reflection capacity for light. By light-reflecting material 7 is meant a material that reflects light far more and absorbs light, for example, a light-colored material typically reflects light much more than absorbs light.
After the light absorbing material 6 and the light reflecting material 7 are coated on the inner walls of the unit grooves 31, the ambient light can be absorbed and the projected light can be reflected.
As shown in fig. 1, the distance between the unit grooves 31 is 1 to 2mm, specifically, the minimum distance between the first inner wall 311 and the second inner wall 312 of two adjacent unit grooves 31 is 1 to 2mm, and in this embodiment, it is preferably 1 mm. The width of the opening of the unit groove 31 is 1-5 mm, and in this embodiment, it is preferably 3 mm.
The flexible substrate layer 5 is used for improving the overall strength of the projection screen and protecting the projection screen. Further, the flexible substrate layer 5 can also be used for improving the surface performance of the screen. The flexible substrate layer 5 is made of a flexible material, and can be rolled.

And a black ink layer 4 is compounded on the surface of one side of the flexible base material layer 5. The black ink layer 4 is formed by applying black ink to the surface of the flexible base material layer 5. The black ink layer 4 is used for absorbing ambient light, improving the display contrast of the projection screen and improving the projection display effect.
Transparent functional layer 3 is located transparent substrate layer 2 with between the black printing ink layer 4, just the opening orientation of transparent functional layer 3's unit groove 31 black printing ink layer 4.
Therefore, the short-focus forward projection type soft curtain of the utility model is formed: as shown in fig. 1, an antiglare layer 1, a transparent substrate layer 2, a transparent functional layer 3, a black ink layer 4, and a flexible substrate layer 5 are sequentially compounded, wherein the antiglare layer 1, the transparent substrate layer 2, the transparent functional layer 3, and the flexible substrate layer 5 are transparent, and the black ink layer 4 is opaque. The transparent functional layer 3 is provided with a unit groove 31, a first inner wall 311 of the unit groove 31 is coated with a light absorbing material 6, and a second inner wall 312 of the unit groove 31 is coated with a light reflecting material 7.
The short-focus forward projection type soft screen of the utility model is a forward projection type projection screen which can be curled and rolled. Wherein, the side of the anti-glare layer 1 is the side watched by the audience, namely the front side; the side of the flexible substrate layer 5 is the side facing away from the viewer, i.e. the back side.
The utility model discloses a soft curtain of short burnt positive formula of throwing's theory of use as follows:
as shown in fig. 1, the short-focus projection device 8 is disposed at a position below the front side of the projection screen, and when the projection light emitted by the short-focus projection device 8 enters the short-focus front projection type soft screen, the projection light sequentially passes through the antiglare layer 1 and the transparent substrate layer 2 and enters the light reflective material layer 7 of the transparent functional layer 3, and is reflected by the light reflective material layer 7 toward the viewer, so that the projection light enters the human eyes to enable the user to view an imaging picture. The anti-glare layer 1 can improve the diffuse reflection effect of the emergent light, so that audiences at various positions can view an imaging picture.
Ambient light, such as light, is typically directed from obliquely above the projection device 8. When the ambient light passes through the anti-glare layer 1 and the transparent substrate layer 2, the ambient light is emitted to the light absorption material 6 layer of the transparent functional layer 3 and absorbed, so that the ambient light cannot enter human eyes as projection light, the interference of the ambient light such as sunlight and lamplight to projection imaging can be greatly reduced, the display effect of a projection picture can be improved, and the contrast and the brightness are improved. In addition, because the black ink layer 4 is arranged at the position between the unit grooves 31, and has light absorption capability, when ambient light in other directions enters, the ambient light will pass through the antiglare layer 1, the transparent substrate layer 2 and the transparent functional layer 3 and enter the surface of the soft black ink layer 4 to be absorbed, so that the interference of the ambient light on projection imaging can be further reduced, and the display effect of a projection picture can be further improved. Further, when there is ambient light on the back side of the projection screen, it can also be absorbed by the black ink layer 4 without affecting the projection effect of the front side projection device 8.
The utility model discloses a short burnt positive formula soft curtain of throwing is applicable to short burnt projection equipment 8, and the interference of its reducible ambient light improves the display effect and the contrast of projection picture.
While the invention has been described with reference to the above embodiments, the scope of the 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 invention.
