Abstract

The invention discloses a preparation method of a composite membrane, a back cover and electronic equipment. The method comprises the steps: printing a color pattern layer on a first diaphragm, wherein the color pattern layer contains a colored tape with the color value greater than a predetermined color value; transferring texture onto a second diaphragm by a texture transfer process; and gluingthe first diaphragm and the second diaphragm to form the composite membrane. According to the embodiment of the invention, a color pattern layer printing process and the texture transfer process are respectively completed on the two diaphragms, so that the colored tape with the color value greater than the predetermined color value in the color pattern layer on the first diaphragm does not affectthe formation of a texture surface on the second diaphragm, and the quality performance of the composite membrane is ensured.

Description

technical field [0001] The invention relates to the technical field of production and manufacturing, in particular to a preparation method of a composite film, a back cover and electronic equipment. Background technique [0002] With the rapid development of electronic equipment, electronic products are updated rapidly, and the competition of electronic products of major brands is fierce. In order to increase the transaction rate of electronic products, it is necessary to enhance the fashion perception value of electronic products. Usually, the back cover of the electronic product is designed in various patterns to enhance the fashion perception value of the electronic product. [0003] At present, by pasting a film with various patterns on the back cover, the film is prepared by transferring complex gradient patterns or darker colors on the base film. Then use the texture transfer process to transfer the texture, and then use optical coating and screen transfer processes ...
