Projection screen features: 360-degree ring screen projection vision is wide, 360-degree spatial imaging performance, very three-dimensional: it displays projection images with high-tech technology, stylish and shocking. It has good physical and mechanical properties, small thermal expansion coefficient (minus 6th power), high heat distortion temperature (above 100 degrees Celsius), high tensile strength, and good weather resistance. It is not sensitive to gas, and has good chemical stability, and does not produce chemical reactions to sulfuric acid, hydrochloric acid and detergents. In the production technology, the principle of diffuse reflection of light is used to carry out special surface treatment on the metal aluminum foil, so that the screen surface is smooth and clean and the curvature is uniform. At the same time, 90% of stray light can be eliminated. Therefore, bright colors and clear images can be maintained even when the room is bright. The screen is sturdy and durable, and the service life can be more than 10 years! Description and features: The 360-degree ring screen projection system uses multiple projectors to form a ring projection screen. The radius of the ring projection screen is 360° arc; due to its large screen radius and 360-degree closure, the audience is in the middle of the ring screen and the vision is completely enclosed , Coupled with the surround sound system, allows the audience to fully experience a highly immersive three-dimensional stereo audiovisual feeling, and obtain a highly immersive visual environment, which is unmatched by traditional screen projection. Program advantages: 1. Broad vision and 360-degree spatial imaging performance. Very three-dimensional; 2. The projected image is displayed with high-tech technology, which is fashionable and shocking; 3. The projected image is bright in color, clear in the picture, strong in space, and has a strong visual impact.
