[0020] figure 1 The flow chart of the preparation method of the optical film provided for the embodiment of the present invention, such as figure 1 As shown, the method may include:
[0021] Step 101, obtaining a mold of a preset optical structure.
[0022] The preset optical structure is a multi-level optical graphic structure.
[0023] For example, the preset optical structure may be a multi-layered small square structure, or the preset optical structure may be a multi-layered small dot structure, and so on. Of course, the preset optical structure may also be other multi-level optical pattern structures, which will not be listed one by one after the implementation of the present invention.
[0024] Step 102, attaching a first explosion-proof film with a predetermined size in the mold, and transferring the texture corresponding to the preset optical structure to the first explosion-proof film through a transfer printing process, so as to form an explosion-proof film with a...

The invention discloses a preparation method of an optical film, a back cover and an electronic device. The method comprises: a die of a preset optical structure is obtained, wherein the preset optical structure is a multi-level optical graphic structure; a first explosion-proof film with a predetermined dimension is pasted in the die and a texture corresponding to the preset optical structure istransferred to the first explosion-proof film by a transferring process, thereby forming a second explosion-proof film having a texture surface; with an optical film plating process, the texture surface of the second explosion-proof film is plated with an electroplated layer, thereby forming a third explosion-proof film; on the basis of a silk-screen printing process, the surface at which the electroplated layer of the third explosion-proof film is located is printed to form an ink layer with a predetermined color, so that a fourth explosion-proof film is formed; and the fourth explosion-prooffilm is placed in a laser engraving machine platform and laser carving moulding is carried out. Therefore, the prepared optical film has advantages of diversified rich glossy layers, natural luster,and good color gradient effect.
Description
technical field [0001] The invention relates to the field of manufacturing technology, in particular to a preparation method of an optical 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. [0003] Currently, the fashion perception value of the electronic product is enhanced by designing the back cover of the electronic product in various patterns. However, the display effect of the pattern on the existing back cover is single and lacks a sense of hierarchy. Contents of the invention [0004] The embodiments of the present invention provide a method for preparing an optical film, a back cover and an electronic device, so as to solve the proble...
