| description | The invention relates to a functional nano-coated high-definition rear-projection display screen and belongs to the material technical field. The display screen comprises a transparent substrate and a functional nano-coating. The substrate is made of transparent materials such as polymethyl methacrylate (PMMA) or polycarbonate (PC). The functional nano-coating contains nano-sized light-scattering fillers such as earth oxides, oxides or sulfides. The refractive index of the filler is in the range from 1.5 to 3.0. The particle size of the filler is in the range from 80 nm to 300 nm. The coating also contains nitrocellulose lacquer, acrylic acid or polyvinyl butyral film-forming agent, thinner or alcohol diluent, high color black liming agent and dispersing agent. The novel nano-coated high-definition rear-projection display screen has the advantages of adjustable high brightness within a large range, large view angle and ultra-high resolution. The functional nano-coating is not limited by the structure and size |
