The anti-glare layer 7 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 7 is a smooth flat surface, and is used for compounding with the grating layer 6. The antiglare layer 7 may be a known antiglare layer 7.
The base material layer 3 is used to improve the strength of the projection film and to provide the adhesive layer 2 and the image forming layer 4. The material for making the substrate layer 3 includes but is not limited to PET material, PVC material, EVA material, PC material, PMMA material, TPU material, etc. The transparent substrate layer 3 is thin and has certain flexibility and can be bent and rolled.
The adhesive layer 2 is used for sticking and has viscosity. The adhesive layer 2 is formed by laminating an adhesive material on the surface of the base material layer 3.
The release film 1 is compounded on the surface of the adhesive layer 2 and used for protecting the adhesive layer 2. When the projection film needs to be pasted on a plane for use, the release film 1 can be torn off to expose the adhesive layer 2, and the projection film is pasted on a wall or glass through the adhesive layer 2. The release film 1 can be a known release film 1.
The imaging layer 4 is compounded on the surface of one side of the base material layer 3 opposite to the adhesive layer 2. The imaging layer 4 is made of a transparent material, for example, a PET material, a PVC material, an EVA material, a PC material, a PMMA material, a TPU material, or the like. The imaging layer 4 is provided with a plurality of strip-shaped unit grooves 41. The unit groove 41 is a hollow groove recessed in one side surface of the imaging layer 4. The opening of the unit groove 41 faces away from the substrate layer 3 and toward the grating layer 6.
As shown in fig. 1 to 3, the unit cell 41 extends from one end of the imaging layer 4 to the other end thereof in the lateral direction. The unit grooves 41 are uniform in size and are arranged uniformly. The cross section of the unit groove 41 is triangular, and in this embodiment, the cross section of the unit groove 41 is isosceles trapezoid. The unit cell 41 is provided with a first inner wall 411 and a second inner wall 412. The first inner wall 411 and the second inner wall 412 abut. The first inner wall 411 and the second inner wall 412 are inclined to the base material layer 3. The inclination angles of the first inner wall 411 and the second inner wall 412 can be set according to requirements.
In this embodiment, the end portions of two adjacent unit grooves 41 are connected, that is, for the unit grooves 41, the ends thereof facing the substrate layer 3 are uniformly spaced, and the ends thereof facing the opening of the grating layer 6 are connected to each other.
The width of the opening of the unit groove 41 is 2-5 mm, and in the embodiment, the width is preferably 5 mm.
In order to reflect the projected light, a reflective material coating 8 is provided on the inner wall of the unit groove 41. In this embodiment, the reflective material coating 8 is disposed on the entire areas of the first inner wall 411 and the second inner wall 412.
The reflective material coating 8 is formed by coating reflective material on the first inner wall 411 and the second inner wall 412.

By reflective material is meant a material that reflects light much more than it absorbs light, e.g., a light-colored material typically reflects light much more than it absorbs light.
After the inner wall of the unit groove 41 is provided with the reflective material coating 8, the projection light can be reflected.
The filling structure 5 is made of a transparent material, such as one of a PET material, a PVC material, an EVA material, a PC material, a PMMA material, and a TPU material. The filling structure 5 is filled in the unit groove 41 to form a damascene structure with the imaging layer 4. In specific implementation, after the reflective material is coated on the inner wall of the unit groove 41 and the reflective material is dried, the unit groove 41 is filled with a transparent fluid material, and after the fluid material is cured, the filling structure 5 can be formed.
The grating layer 6 is used for shielding and absorbing the ambient light so as to reduce the interference of the ambient light to the projection picture. The grating layer 6 is compounded on the surfaces of the imaging layer 4 and the filling structure 5. In other words, the grating layer 6 and the substrate layer 3 are respectively located at two sides of the imaging layer 4 and the filling structure 5.
A plurality of parallel and spaced grating microstructures 61 are arranged in the grating layer 6, and transparent materials are filled between the grating microstructures 61, so that transparent areas 62 are formed between the grating microstructures 61. For the grating layer 6, the transparent regions 62 occupy a major portion, and the non-transparent regions 62 of the grating microstructures 61 occupy a minor portion.
The grating microstructures 61 are used for blocking ambient light and absorbing ambient light. In this embodiment, the grating microstructure 61 is made of a black ink material, and has a light absorption capability. The grating microstructure 61 is perpendicular to the substrate layer 3 and is arranged at a position where two adjacent unit grooves 41 are connected. The distance between the unit grooves 41 is identical to the opening distance of the unit grooves 41. The height of the unit groove 41 is 1-3 mm, and in the embodiment, it is preferably 3 mm.
The transparent material filled between the grating microstructures 61 may be one of a PET material, a PVC material, an EVA material, a PC material, a PMMA material, and a TPU material.
In specific implementation, the grating microstructures 61 may be coated and printed on the surfaces of the imaging layer 4 and the filling structure 5, then a transparent material is filled between the grating microstructures 61, and after the transparent material is cured, the grating layer 6 with the grating microstructures 61 inside can be formed.
Since the grating microstructure 61 has a minute structure, it cannot be recognized by human eyes, and in fig. 1 to 3, in order to show the specific structures of the unit grooves 41 and the grating microstructure 61, the ratio of the unit grooves 41 to the grating microstructure 61 is enlarged, and in practice, the ratio of the unit grooves 41 to the grating microstructure 61 is not as general as that shown in fig. 1 to 3. Therefore, fig. 1 to 3 do not represent the approximate proportion or the correct proportion of the structure of the grating type light-resistant projection film of the present invention, and they are only used for displaying the structure composition of the present invention. In addition, because the structure of the grating microstructure 61 is fine and cannot be perceived by naked eyes of a human body, even if the grating microstructure 61 is made of a black material and is different from the imaging layer 4, the grating microstructure does not affect the visual perception, a black line cannot be formed before the visual perception, and a user cannot perceive that a black line exists on the projection screen.
By this, just formed the utility model discloses an anti light projection membrane of grating formula: as shown in fig. 1 to 3, a release film 1, an adhesive layer 2, a substrate layer 3, an imaging layer 4, a filling structure 5, a grating layer 6 and an antiglare layer 7 are sequentially disposed, wherein a unit groove 41 is disposed in the imaging layer 4, and a reflective material coating 8 is disposed on an inner wall of the unit groove 41 and used for reflecting projection light; grating microstructures 61 are spaced in the grating layer 6 and are used for shielding and absorbing ambient light.
The grating type light-resistant projection film of the utility model is a front projection type screen, wherein, one side of the anti-glare layer 7 is the side watched by audiences, namely the front side; the side of the release film 1 and the adhesive layer 2 is the side facing away from the viewer, i.e. the back side. In use, the projection device 9 is disposed on the front side, i.e., the side of the antiglare layer 7.
As shown in fig. 3, the usage principle of the grating type light-resistant projection film of the present invention is as follows:
when in use, the release film 1 is torn off, and the projection film is stuck on a plane such as a wall, glass and the like for use; the projection device 9 is erected at the front side position of the projection film, when projection light emitted by the projection device 9 is emitted to the projection film, the projection light sequentially passes through the antiglare layer 7, the transparent region 62 in the grating layer 6 and the transparent filling structure 5 and is emitted onto the reflective material coating 8, and after being reflected by the reflective material coating 8, the projection light passes through the filling structure 5, the transparent region 62 in the grating layer 6 and the antiglare layer 7 and is emitted towards the audience, so that the audience can watch a projection picture.
And for the ambient light, because the light source of ambient light generally is located above the central horizontal line of visual angle in the dead ahead of the projection membrane, like sunlight, fluorescent lamp etc., therefore, when the ambient light shines from the oblique top of projection membrane, it can be sheltered from by the grating microstructure 61 that the interval set up, and absorbed, thereby make the ambient light not shine on reflecting material coating 8, and then the ambient light that makes can't mix with the projection light of projection equipment 9, and then can't weaken the visual sense of projection light, consequently, alright form more clear, the contrast is higher, the brighter projection picture on the formation of image membrane. When light rays of a projection picture enter pupils, visual perception with clearer imaging picture, higher contrast and brighter brightness can be formed on human eyes, and a very clear and perfect picture is presented to a user.
It should be noted that, although the grating microstructure 61 has the functions of blocking light and absorbing light, it does not cause a significant absorption weakening effect on the projection light from the projection device 9, because the incident angle of the projection light of the projection device 9 is significantly different from the incident angle of the ambient light, only a very small portion of the projection light is absorbed, and most of the projection light can still perform normal projection imaging, and human eyes cannot distinguish such a slight difference, so that the very small portion of the projection light is absorbed and does not affect the visual image finally felt by the user. What the user can feel still is even and continuous clear picture, compares with current projection screen, and the user only can feel the utility model discloses an anti light projection membrane of grating formula's projection picture is more clear, the contrast is higher. In addition, in actual use, the angle between the grating microstructure 61 and the ambient light and the projection light can be adjusted by adjusting the placement positions of the projection film and the projection device 9, so that the optimal projection effect can be achieved.
The utility model discloses an interference of the reducible ambient light of grating formula anti light projection membrane 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.
