The invention discloses a microbead projection screen which comprises a base material, a PET black layer formed on one side of the base material and a function film formed on the other side of the base material. The function film comprises a light absorption layer and microbeads protruded out of the upper surface of the light absorption layer. The function film comprises, by mass, 87% of polyvinyl alcohol, 2% of matt white colorant, 1% of flame retardant, 3.5% of bridging agent, 0.6% of stabilizer, 1.2% of defoamer, 1% of wetting agent, and the balance microbeads. The invention further discloses a method for manufacturing the microbead projection screen. According to the microbead projection screen, projection screen brightness is high, the gain is increased by 2.8%, the effective scattering angle is larger than 32 degrees, and the microbead projection screen has the advantages of being high in resolution and good in color reproduction. The microbeads are evenly and densely distributed and do not drop easily.
Description
technical field [0001] The application belongs to the field of projection, and in particular relates to a bead projection screen and a manufacturing method thereof. Background technique [0002] At present, projection technology is used in small mobile business presentations, multimedia conference rooms, classrooms, stadiums, churches, commercial places, large auditoriums, virtual displays and even super-large screens as large as movie theaters. Simply put, projection technology is to project the light from the projector onto the projection screen, form an image on the projection screen, and then reflect the light to the human eye. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. [0003] Projection screens can be generally divided into reflective and transmissive types in terms of function; reflective type is used for front projection, and transmissive type is used for rear projection; front projection screen...
