Background
With the improvement of the quality of life of people, many high-income families have been updated in the aspect of movies and televisions, and further, the light projection resistant era is promoted. However, many buyers have a question of being resistant to the new form of projection products, such as light curtains: what is anti light curtain, it compares traditional projection curtain product and has which advantage, and the biggest advantage of anti light curtain just can promote the picture effect of projection under light interference, draws back the curtain daytime, opens all can use under the environment of lamp night, lets people take a refuge the environment of watching of lacquer black all around. The light-resistant curtain is characterized in that: by resisting light, filtering and absorbing ambient light, the effects of enhancing the contrast, the light and shade level, the color brightness, the hue, the saturation and the like of the picture are achieved. The anti light curtain then realizes anti light through optical coating and physical structure, except absorbing ambient light all around, can also control the regional dereflection of visual angle at projector incident ray place to people's eye, the minimize scatters the projection light in the space, the utilization efficiency of light energy will improve greatly like this, so eyes received projection light energy has more, the ambient light of interference has reduced, and is colored, and luminance, the contrast ratio can all obtain effectual promotion, this also is why the effect of anti light curtain will be better than the reason place of ordinary diffuse reflection screen far away.
Currently, projection screen is a product used in movies, offices, home theaters, large conferences, etc. for displaying images and video files. The projection screen has different specifications and different projection distances according to different use requirements. In the projection process, in order to reduce the influence of ambient light, the projection process needs to be performed in a dark environment, however, when sunlight is strong, the ambient light still enters the back projection screen from the peripheral side of the projection screen, and the imaging quality is affected. Therefore, it is necessary to provide a further solution to the above problems.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a positive projection black grid projection screen which has excellent optical performance, strong light resistance and good visual effect.

Furthermore, the transparent grid-shaped optical film layer comprises black grid light absorption layers and transparent PU prism layers which are alternately distributed.
Furthermore, the imaging layer is made of transparent PET (polyethylene terephthalate), the anti-glare layer is an environment-friendly pressure-sensitive adhesive, and the scratch-resistant layer is a polyester film coated with a release agent.
Furthermore, the optical glass beads are uniform in bead size and are arranged in a single-layer structure.
Furthermore, the material of the optical glass beads may be glass formed by one of titanium dioxide, barium monoxide, zirconium dioxide, zinc monoxide and silicon dioxide, or glass formed by combining a plurality of substances of titanium dioxide, barium monoxide, zirconium dioxide, zinc dioxide and silicon dioxide, or plastic resin.
Furthermore, the optical glass beads are vacuum coating film 100-600 meshes, the particle size is 0.02-0.10 mm, and the refractive index is 1.5-2.5.
Further, the adhesive comprises silicon dioxide, nanoscale hydrate, aluminum oxide and graphene, and is uniformly coated on the surface of the imaging layer after being mixed according to a certain proportion.
Compared with the prior art, the invention has the beneficial effects that: in the invention, the prism screen with a black grid structure is adopted in the transparent grid-shaped optical film layer to optimize the black grid layer, and the prism screen with a triangular prism structure is used to effectively absorb 95 percent of ambient light and lamplight and restore the real projection color compared with 10 times of a common projection screen,
the reflection of ambient light from the surroundings is facilitated, and the definition of projection imaging is further improved; for example, a 100-inch curtain has 1100W prismatic structures, so that the curtain is not only light-resistant, but also has uniform diffuse reflection, and the picture quality putty achieves real 4K ultrahigh definition, has excellent light resistance and can be freely handled in a bright environment; the design that the adhesive comprises silicon dioxide, nanoscale hydrated oxide, aluminum oxide and graphene enables light projection to be softer and finer, directional projection is achieved through the graphene, and photons are not polarized; in a word, the front projection black grid projection screen of the invention uses multilayer structure and material to effectively absorb the ambient light and lamplight, so that the picture presents high contrast and bright color, and has excellent optical performance, strong light resistance and good visual effect.
