发明名称 METHOD FOR HIDING SCRATCHES OR IMPERFECTIONS ON THE SURFACE OF SCREENS USED IN PROJECTION SYSTEMS
摘要 A novel light diffusing resin (material) has been invented which combin es excellent light diffusing properties with high light transmission. The combination of properties is possible because the material does not significantly backscatt er light. Also, the material exhibits good contact clarity. This light diffusing material is an excellent choice for use in projection systems as a method for hiding scratches or imperfections in a rear projection screen such as a TV screen, rear projecte d slides, liquid crystal display (LCD screens or a thin layer electric decoration shee t by using a plastic sheet containing specific light diffusing particles therein and havi ng a combination of properties including high light transmission properties that does not significantly backscatter ambient light from outside illuminating sources.</ SDOAB>
