Nanometer microcrystal mixed optical structure back projection high-definition image film and back projection screen

Abstract

The invention discloses a nanometer microcrystal mixed optical structure back projection high-definition image film. The nanometer microcrystal mixed optical structure back projection high-definitionimage film comprises a substrate layer, a nanometer microcrystal and nanometer micro ball mixed imaging coating layer and a back adhesive layer; the nanometer microcrystal and nanometer micro ball mixed imaging coating layer is formed by uniformly coating one surface of the substrate layer with nanometer microcrystal, nanometer micro balls and an adhesive based on a proportion; and the back adhesive layer is arranged on the other surface of the substrate layer for pasting external supports. The nanometer microcrystal and the nanometer micro balls are mixed and coated on the substrate layer, sothat compared with an image film with separated inorganic silicon particle coating layer and glass micro ball coating layer, the image film disclosed in the invention can eliminate projector light source light spots in a more all-around manner, the image angle of visibility can be enlarged to 178 degrees, and brightness, color saturation degree and light resistance and eye protection performanceof the projection image are improved, so that the image film is applicable to all projectors of different lenses on the market.

Description

technical field [0001] The invention relates to the field of optical projection technology, in particular to a rear-projection high-definition image film and a rear-projection screen with a nano-microcrystalline mixed optical structure. Background technique [0002] Nowadays, projection technology is widely used in life and work, especially in large conference rooms, command and control centers, training and education structures, exhibition halls, exhibition halls, airports, window displays and other important occasions. [0003] However, in reality, projection screens often work in bright environments, and their surfaces are easily affected by strong light, resulting in unclear, uneven, glare, and severe white fog-like images. And these phenomena will greatly reduce the contrast and brightness of the picture, which will easily cause the user to see it unclearly, seriously affect the perception, and easily lose its own display, demonstration or advertising effect.

[0003] However, in reality, the projection screen often works in a bright environment, and its surface is very easy to be affected by strong light, resulting in unclear, uneven, glare, and severe white fog in the imaging picture.

And these phenomena will greatly reduce the contrast and brightness of the screen, which will easily cause users to see unclearly, seriously affect the perception, and easily lose its own display, demonstration or advertising effect
