  • Optical film and liquid crystal display
    Patent number: 9201267
    Abstract: An optical film includes a first optical layer and a second optical layer. The first optical layer is disposed above the second optical layer. The second optical layer is a composite material layer, which includes a base material and a doping layer disposed in the base material. The optical film recycles an exterior light source and improves the utilization rate of the light source.
