Through the light of other colours beyond red green blue trichromatic colour is absorbed to filter coating 9, can effectively avoid in the ambient light the light beam of other colours beyond red green blue trichromatic colour to get into transparent substrate layer 2 and cause the influence to the formation of image effect, avoids leading to the relatively poor problem of formation of image effect, and then contrast, color reduction, luminance gain and the accurate of colour when improving projection screen formation of image. The filter film 9 may be a known filter film.

As shown in fig. 1 to 3, the transparent substrate layer 2 is transparent and allows light to pass therethrough. The transparent substrate layer 2 is compounded on the inner side surface of the filter film 9. 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. When light passes through the transparent substrate layer 2, the light will be refracted within the transparent substrate layer 2.

As shown in fig. 1 to 3, the micro-groove structure layer 3 is laminated on the transparent substrate layer 2 by a known process, such as thermal compression lamination, adhesive lamination, etc.

The micro-groove structure 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 micro-groove structure layer 3 is provided with a plurality of strip-shaped unit micro-grooves 31. The unit micro-grooves 31 are hollow grooves recessed in one side surface of the micro-groove structure layer 3. The openings of the unit micro grooves 31 face away from the transparent substrate layer 2 toward the imaging film 5 and the black light-shielding film 6.

As shown in fig. 1 to 3, the unit micro grooves 31 extend from one end of the micro groove structure layer 3 to the other end thereof in the lateral direction. Two adjacent unit micro grooves 31 are spaced in parallel. The unit micro grooves 31 are uniform in size and are uniformly arranged.

As shown in fig. 1 to 3, the cross section of the unit micro groove 31 is triangular, and in this embodiment, the cross section of the unit micro groove 31 is isosceles trapezoid. The unit micro grooves 31 are provided with first inner walls 311 and second inner walls 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 and the second inner wall 312 are inclined to the transparent substrate layer 2 and the imaging film 5. The inclination angles of the first inner wall 311 and the second inner wall 312 can be set as required, in this embodiment, the acute angle between the first inner wall 311 and the second inner wall 312 and the transparent substrate layer 2 is 60-85 °.

As shown in fig. 1 to fig. 3, in order to absorb the ambient light and reduce the interference of the ambient light to the projection imaging, at least a light absorbing material coating 7 is disposed on the first inner wall 311. In this embodiment, the first inner wall 311 and the second inner wall 312 are both provided with a light absorbing material coating 7.

The light absorbing material 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 is black ink, and is coated on the first inner wall 311 and the second inner wall 312 by a known coating process.

It should be noted that the light absorbing material means that the material has a far greater absorption capacity than its reflection capacity, for example, dark materials generally have a far greater absorption capacity than its reflection capacity.

After the light absorption material coating 7 is arranged on the inner wall of the unit micro-groove 31, the ambient light can be absorbed.

As shown in fig. 1 to 3, the unit micro grooves 31 are spaced apart by a distance of 2 to 5mm, and specifically, the end portions of the first inner wall 311 and the second inner wall 312 of two adjacent unit micro grooves 31 are spaced apart by a distance of 2 to 5mm, which is preferably 4mm in this embodiment. The width of the opening of the unit micro-groove 31 ranges from 1 mm to 3mm, and in the present embodiment, it is preferably 2 mm.

Since the structure of the unit micro-grooves 31 is very small, the structure of the light absorbing material coating 7 is also very small and cannot be identified by human eyes, while the proportion of the unit micro-grooves 31 is enlarged in order to show the specific structures of the unit micro-grooves 31 and the light absorbing material coating 7 in fig. 1 to 3, and in practice, the proportion of the unit micro-grooves 31 to the micro-groove structure layer 3 is not as general as that shown in fig. 1 to 3. Therefore, the drawings 1 to 3 do not represent the approximate proportion or the correct proportion of the light-resistant front projection type soft screen of the present invention, and they are only used for showing the structural composition of the light-resistant front projection type soft screen of the present invention. In addition, since the structure of the unit micro-grooves 31 is fine and cannot be perceived by human eyes, even if the light absorbing material coating 7 is made of dark material such as black and has a color different from that of the imaging film 5, the visual perception is not affected, and neither a single black line is formed before the visual perception nor a single black line exists on the projection screen.

The transparent microstructure 4 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 transparent microstructures 4 are filled in the unit micro-grooves 31 to form a damascene structure with the micro-groove structure layer 3. In specific implementation, after the light absorbing material is coated on the inner wall of the unit micro-groove 31 and the light absorbing material is dried, the unit micro-groove 31 is filled with the fluid material used by the transparent microstructure 4, and after the fluid material is solidified, the transparent microstructure 4 can be formed.

The imaging film 5 is used for projection imaging, and when projection light emitted by the projection device 8 is incident on the imaging film 5, a projection picture can be formed on the imaging film 5. The imaging film 5 may be selected from known positive-projection imaging films 5, which are typically reflective imaging films 5, which are typically silvery white or off-white in color with high reflectivity.

The imaging film 5 is compounded on the surface of the micro-groove structure layer 3 and is attached to the surface of the transparent microstructure 4. In other words, the imaging film 5 and the transparent substrate layer 2 are respectively located at two sides of the micro-groove structure layer 3 and the transparent microstructure 4.

The black light-shielding film 6 is used to shield light from the back side of the imaging film 5 to improve the projection effect. The black shading film 6 is compounded on the back side of the imaging film 5, namely the side opposite to the micro-groove structure layer 3. When ambient light is on the back side, the black light shielding film 6 can absorb the ambient light to reduce the interference of the ambient light, so as to improve the front projection display effect.

By this, just formed the utility model discloses a soft curtain of anti light positive projection: as shown in fig. 1 to 3, the antiglare layer 1, the light filter film 9, the transparent substrate layer 2, the micro-groove structure layer 3, the light-absorbing material coating 7, the transparent microstructure 4, the imaging film 5, and the black light-shielding film 6 are sequentially disposed, wherein the antiglare layer 1, the transparent substrate layer 2, and the micro-groove structure layer 3 are transparent, the light-absorbing material coating 7 and the black light-shielding film 6 are opaque, and the imaging film 5 is opaque.

The utility model discloses a soft curtain of anti light positive projection is soft screen, and it can carry out the rolling. The utility model discloses a light-resistant front projection type soft screen is a front projection type screen, wherein, one side of the anti-glare layer 1 is the side watched by audiences, namely the front side; the side of the imaging film 5 is the side facing away from the viewer, i.e. the back side. In use, the projection device 8 is disposed on the front side, i.e., the side of the antiglare layer 1.

The utility model discloses a use principle of anti light positive projection type soft curtain as follows:

as shown in fig. 1 to 3, the projection device 8 is disposed at a front side position of the projection screen, when the projection light emitted by the projection device 8 is incident on the projection screen, the projection light sequentially passes through the antiglare layer 1, the transparent substrate layer 2, and the micro-groove structure layer 3 and is incident on the imaging film 5, and is reflected by the imaging film 5 to form an image, and the reflection light passes through the micro-groove structure layer 3, the transparent substrate layer 2, and the antiglare layer 1 and is emitted toward a viewer side, so that the viewer views a projection picture.

Because the light source of the ambient light is generally located above the central horizontal line of the visual angle in front of the projection screen, such as sunlight and a fluorescent lamp, when the ambient light irradiates from the oblique upper side of the projection screen, the ambient light can be shielded by the light absorption material coating 7 arranged at intervals and absorbed, so that the ambient light cannot irradiate the area of the imaging film 5 between the unit microgrooves 31, or a few parts of the ambient light irradiate the imaging film 5, and further the ambient light cannot be mixed with the projection light of the projection equipment 8 or a small amount of the ambient light cannot weaken the visual sense of the projection light, and therefore, a clearer projection picture with higher contrast and brighter brightness can be formed on the imaging film 5. 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 light absorbing material coating 7 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 8, because the incident angle of the projection light of the projection device 8 is significantly different from the incident angle of the ambient light, only a very small portion of the projection light will be 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 is still even and continuous clear picture, compare with current projection screen, the user only can feel the utility model discloses a projection picture of anti light positive projection type soft curtain is more clear, the contrast is higher. In practical use, the angle between the light absorbing material coating 7 and the ambient light and the projection light can be adjusted by adjusting the position of the projection screen and the projection device 8, so that the best projection effect can be achieved.

The utility model discloses a but interference of the reducible ambient light of anti light positive projection formula soft curtain improves the display effect and the contrast of projection picture.
