Abstract

An optical film comprises a base layer, an interlayer and a cover layer; the base layer has a flat base surface and an upper surface of the base layer opposite to the lower surface of the base layer, the upper surface of the base layer is an uneven structured surface, the base layer has a first refractive index; the interlayer having a lower surface of the interlayer and an upper surface of the interlayer opposite the lower surface of the interlayer, the lower surface of the interlayer being disposed on the upper surface of the base layer, the interlayer having a second refractive index and conforming to the uneven structured surface of the upper surface of the substrate; the cover layer has a lower surface of the cover layer and an upper surface of the cover layer opposite to the lower surface of the cover layer, the lower surface of the cover layer being provided on the upper surface of the interlayer, the upper surface of the cover layer being a flat surface parallel to the lower surface of the base layer, the cover layer has a third refractive index; The first and third refractive indices are about the same, the second refractive index is substantially greater than the first and third refractive indices, and the change in the interlayer thickness is in the range of + / - 50% as compared with the average thickness. The present invention greatly simplifies the manufacturing process requirements and enables low cost production.

Description

technical field [0001] The present invention relates generally to an optical film, and more particularly, to an optical film that transmits an image with negligible distortion while diffusely reflecting incident light. [0002] The optical film can be widely used as a window film for buildings, where the "frosted glass" appearance of the film will provide some privacy inside the building. The film can also reduce the specular reflection of glass windows when used as a window film. The optical film can also be used as an image combiner, allowing a viewer to simultaneously observe the image transmitted through the film and the image formed on the film. The present invention further relates to an optical film that can be used as a partition wall to provide differentiated visual effects to objects on both sides of the partition wall. Background technique [0003] Optically transparent films have a wide variety of applications, such as for glazing in buildings and as optical la...
