Patent ID: 11226516

Abstract:
An optical composite film, comprising a uniaxial optical film layer, a substrate layer, and a reflective raster film layer. The uniaxial optical film layer comprises a plate-like portion and multiple refractive portions provided at one side of the plate-like portion. The multiple refractive portions are selected one of arc-shaped columns and quadrangular prisms. The material of the uniaxial optical film layer is a disc-like liquid crystal molecule material. The substrate layer is stacked at one side of the plate-like portion close to the refractive portion. The multiple refractive portions are accommodated in the substrate layer. The ordinary refractive index of the uniaxial optical film layer is greater than the refractive index of the substrate layer. The reflective raster film layer is provided at one side of the substrate layer distant from the uniaxial optical film layer.
