Abstract

The invention provides a method for manufacturing cavity. The method comprises the following steps: first providing a solution containing a solvent, a solute and a plurality of nanoparticles; then providing a first substrate; coating the solution on the first substrate by spinning and volatilizing the solvent on the first substrate to form a first cavity, which has a plurality of first holes on an upper surface. The invention also includes an optical film with protuberant patterns and made of the cavity. The invention can lower production cost of the optical film and process complexity.

Description

technical field [0001] The invention relates to a method for making mold cores, especially a method for making mold cores by spin coating. Background technique [0002] In recent years, with the maturity and application of various types of display technologies, the production technologies of various types of optical films used in displays are also developing vigorously, such as optical films such as diffusion films and brightness enhancement films. Generally speaking, this type of optical film utilizes microstructures formed on the surface of the film to achieve the effect of scattering or concentrating light. [0003] The conventional manufacturing method for forming the surface microstructure of the optical film is to first form the microstructure pattern on the mold core by using lithography and etching processes, and then use a roller printing process to transfer the microstructure pattern to the surface of the optical film. However, the process cost and process complex...
