  • Projection screen and light absorbing film
    Patent number: 10527922
    Abstract: A projection screen including a light absorbing film and a projection film is provided. The light absorbing film includes a transparent layer and a plurality of light absorbing microstructures, where the light absorbing microstructures are embedded in the transparent layer and arranged at intervals, each of the light absorbing microstructures is asymmetrical to a reference plane, the transparent layer has two surfaces opposite to each other, and the reference plane passes through a geometric center of each of the light absorbing microstructures and is parallel to each of the surfaces, and there is a space between each of the light absorbing microstructures and each of the surfaces. The projection film and the light absorbing film are stacked on each other. A light absorbing film is also provided, and the projections screen and the light absorbing film have good optical quality.
