  • Patent number: 11921412
    Abstract: A method for manufacturing a projection screen and a projection screen are provided. The method includes: preparing a substrate; under a first preparation condition, forming a reflective layer by vacuum plating above the substrate; and under a second preparation condition, forming a diffusion layer by the vacuum plating on the reflective layer. The second preparation condition is different from the first preparation condition, and a sputtering power in the second preparation condition is higher than a sputtering power in the first preparation condition.
    Type: Grant
