The transparent substrate layer 1 can be made of a PET material, a PVC material, an EVA material, a PC material, a PMMA material or a TPU material. In this embodiment, the transparent substrate layer 1 is made of a PVC material.
As shown in fig. 1 to 3, the transparent microstructures 2 are disposed on the transparent substrate layer 1 at regular intervals. The transparent microstructures 2 are protruded structures relative to the transparent substrate layer 1. The transparent microstructures 2 are spaced from each other, so that a light-transmitting area can be formed between the transparent microstructures, and background content can be observed conveniently.
In this embodiment, as shown in fig. 1 to fig. 3, the cross section of the transparent microstructure 2 is a right triangle, and the transparent microstructure has a first surface 21 and a second surface 22. The first surfaces 21 of the transparent microstructures 2 are perpendicular to the transparent substrate layer 1, and the second surfaces 22 are oblique to the transparent substrate layer 1. The angle at which the second surface 22 is inclined can be set as desired, which is related to the focal length of the projection device 7.
As shown in fig. 1 to 3, the position where the first surface 21 and the second surface 22 are connected is the top angle of the transparent microstructure 2. The top corners of the transparent microstructures 2 face away from the transparent substrate layer 1 and towards the antiglare layer 6.

The dimensional parameters of the transparent microstructures 2 are as follows: the distance between the first surfaces 21 of two adjacent transparent microstructures 2 is 2 mm-5 mm, preferably 4mm in the embodiment; the distance between the ends of the first surface 21 and the second surface 22 of the same transparent microstructure 2 is 0.5mm to 1.5m, preferably 1mm in the embodiment; the height of the first surface 21 is 0.5mm to 2m, and in the present embodiment, it is preferably 1.5 mm.
As shown in fig. 1 to 3, the transparent microstructures 2 and the transparent substrate layer 1 may be combined together or may be integrally formed. In this embodiment, the transparent microstructures 2 and the transparent substrate layer 1 are integrally formed and are made of a PVC material. During processing, the transparent substrate layer 1 with the transparent microstructures 2 can be directly processed by using a corresponding die.
As shown in fig. 1 to 3, in order to block and absorb the ambient light to improve the display brightness and contrast of the projection image, a light absorbing material coating 3 is disposed on the first surface 21. The light absorbing material coating 3 is formed by applying a light absorbing material to the first surface 21 by a known process. In this embodiment, the light absorbing material is black ink.
As shown in fig. 1-3, a coating 4 of imaging material is provided on the second surface 22 for reflective imaging. The imaging material coating 4 is formed by applying a light-colored ink to the second surface 22.
As shown in fig. 1 to 3, after the light absorbing material coating 3 is disposed on the first surface 21 and the imaging material coating 4 is disposed on the second surface 22, a transparent material is filled between the transparent microstructures 2, and after the transparent material is cured, a light-transmitting region 5 is formed between the transparent microstructures 2.
The transparent material includes, but is not limited to, a PET material, a PVC material, an EVA material, a PC material, a PMMA material, a TPU material, and the like. In this embodiment, the transparent material is a PET material.
As shown in fig. 1 to 3, after the light transmission regions 5 are formed between the transparent microstructures 2, the surfaces of the light transmission regions 5 are flush with the two ends of the transparent microstructures 2.
As shown in fig. 1 to 3, the anti-glare layer 6 is used to improve light scattering and prevent light from being emitted in a single direction, so as to achieve the purpose of anti-glare. The anti-glare layer 6 is transparent, and the outermost surface of the anti-glare layer has certain roughness, so that diffuse reflection of light can be enhanced. The inner side surface of the anti-glare layer 6 is a smooth flat surface, and the anti-glare layer is compounded on the surfaces of the transparent microstructures 2 and the light transmission area 5 through a known process and is opposite to the transparent substrate layer 1.
When in processing, after the light transmission area 5 is formed between the transparent microstructures 2, an anti-dazzle layer 6 is compounded on the surface of the transparent microstructures.
By this, just formed the utility model discloses a transparent holographic imaging membrane: transparent microstructures 2 are distributed on the transparent substrate layer 1 at intervals, and light absorption material coatings 3 are arranged on first surfaces 21 of the transparent microstructures 2 and used for absorbing ambient light; the second surface 22 of the transparent microstructure 2 is provided with a coating 4 of imaging material for reflective imaging. A light transmission area 5 is filled between the transparent microstructures 2; an anti-glare layer 6 is compounded on the surfaces of the light-transmitting area 5 and the transparent microstructure 2 and used for improving the diffuse reflection effect.
The utility model discloses a transparent holographic imaging film is just throwing formula imaging film, and simultaneously, it has light trap 5, can convenience of customers see the background content of imaging film rear side. When in use, one side of the anti-glare layer 6 is the side watched by audiences, namely the front side; the transparent substrate layer 1 side is a side facing away from the viewer, i.e., a back side. In use, the projection device 7 is disposed on the front side, i.e., the side of the antiglare layer 6.
For the transparent holographic imaging film of the embodiment, because the transparent microstructures 2 have a very fine structure, are arranged at equal intervals in the transverse direction, account for the whole imaging film in a very small proportion, and the dark light absorbing material coating 3 is perpendicular to the transparent substrate layer 1, human eyes cannot detect black stripes on the imaging film as a whole, so that the imaging film seen by human eyes is wholly light-colored and transparent when no projection light exists, and viewers can directly see through the imaging film to see background content on the rear side of the imaging film. The whole transparent holographic imaging film formed in this embodiment is in a film shape, and the thickness of the film is relatively thin, which is about 2 mm.
As shown in fig. 3, the use principle of the transparent holographic imaging film of the present invention is as follows:
when the anti-glare projection device is used, the projection device 7 is erected in the front side direction of the imaging film, and projection light emitted by the projection device 7 enters the imaging film, is refracted by the transparent anti-glare layer 6 and the light-transmitting region 5 to reach the imaging material coating 4, is reflected by the imaging material coating 4, is refracted by the light-transmitting region 5 and the anti-glare layer 6 to be reflected towards a viewer, so that the viewer can watch a projection picture.
And because the transparent regions 5 are formed between the transparent microstructures 2, the background content at the back side of the imaging film can be observed through the transparent regions 5, so that a viewer can observe the foreground content imaged on the imaging film and the background content at the back side of the imaging film.
And to the ambient light of front side, because the light source of ambient light generally is located the visual angle central horizon in the dead ahead of projection membrane more than, like the sunlight, fluorescent lamp etc., consequently, when ambient light shines from the oblique top of projection membrane, it can be sheltered from by transparent microstructure 2 that the interval set up, and absorbed by absorption light material coating 3, thereby make ambient light not to on imaging material coating 4, or shine imaging material coating 4 on seldom, and then the ambient light that makes can't mix with the projection light of projection equipment 79, and then can't weaken the visual sense of projection light, thereby can form more clear, the contrast is higher, the bright projection picture of luminance on imaging membrane.
It should be noted that, in the structure illustrated in the drawings of the specification, the size of the transparent microstructure has been enlarged to embody the structure of the transparent microstructure, and the ratio of the size to the size of the imaging film is not as general as that illustrated in fig. 1 to 3.
The utility model discloses a transparent holographic imaging film both can show the projection picture, can see the background content again, can also improve prospect projection picture luminance and contrast simultaneously, and it is still easily processed moreover, and the process size can not be restricted, therefore, it has very strong practicality.
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.
