[0002] A projection screen is a plane that forms an image by projecting light onto it from a projector. It is a passive imaging material. For a front projection screen, the images we usually see on the screen are all images formed by light reflected onto the retina in our eyes. The light projected by the projector is actually a kind of energy, that is, light energy. The diffuse reflection projection screen that we usually see, the light projected onto it will diffusely reflect 180° into the space. Compared with traditional projection screens, anti-light screens have many advantages, the biggest advantage of which is that they can improve the picture effect under the interference of light.
