Abstract

The embodiment of the invention discloses a preparation method of a diffusion sheet, the diffusion sheet and a terminal, and belongs to the technical field of optics. The preparation method comprises the following steps: processing a base material, and heating the base material to enable the first surface of the base material to be in a semi-molten state; processing the first surface, and imprinting the first surface by using a first template to form a first microstructure on the first surface; and cooling to cure the base material, and coating the first surface with a first protective layer to obtain the diffusion sheet. In the embodiment of the invention, the surface of the base material in the semi-molten state is impressed to form the microstructure, so that the processing technology requirement can be reduced. Meanwhile, the surface provided with the microstructure is coated with the protective layer, so that the surface provided with the microstructure in an impressed mode is smooth, foreign matter attachment points do not exist, and cleaning is convenient. The protective effect can be achieved, and scratching is avoided when the diffusion sheet makes contact with other objects; and the light can be scattered more uniformly.

Description

technical field [0001] The present application relates to the field of optical technology, in particular to a method for preparing a diffuser, a diffuser and a terminal. Background technique [0002] Diffusers are widely used in equipment such as imaging systems and display systems because of their ability to scatter light and expand the divergence angle of light. [0003] In the prior art, the surface of the diffuser is provided with microstructures, so as to achieve uniform diffusion and divergence of light through the microstructures. However, the microstructure is easily scratched during use or transportation, which affects the use effect of the diffuser. Contents of the invention [0004] The embodiment of the present application provides a method for preparing a diffuser, a diffuser and a terminal, which can solve the problem that the surface microstructure of the existing diffuser is easily scratched and affects the use effect of the diffuser. Described technical ...
