Abstract

A manufacturing method of a cover plate of a fingerprint identification module disclosed by the invention includes the following steps: providing a substrate, wherein the substrate includes a first surface and a second surface which are opposite to each other; forming a texture and color layer on the first surface; forming an enhanced transmission layer on the texture and color layer; forming a light shield layer on the enhanced transmission layer; and forming an anti-fingerprint layer on the second layer. The cover plater obtained by the manufacturing method of the cover plate is provided with required appearance colors by forming an ink layer on the substrate. The cover plate has a micro texture effect by forming a texture layer on the ink layer. The anti-dirt performance of the cover plate can be improved by forming the anti-fingerprint layer on the substrate. Meanwhile, the structure of the cover plate includes the anti-fingerprint layer, the substrate, the ink layer, the texture layer, the enhanced transmission layer and the light shield layer in order, and so the color brilliance degree, micro texture effect and light and shadow effect of the cover plate is good. The invention also discloses an electronic device, the fingerprint identification module and the cover plate of the fingerprint identification module.

Description

technical field [0001] The invention relates to the technical field of consumer electronic products, in particular to a method for manufacturing a cover plate of a fingerprint recognition module, a cover plate of the fingerprint recognition module, a fingerprint recognition module and an electronic device. Background technique [0002] Fingerprint identification modules are widely used in electronic devices such as mobile phones, tablet computers, smart bracelets, and door locks, and can be used to quickly unlock electronic devices. However, the hue brightness and microscopic texture effect of the cover plate of the existing fingerprint identification module are poor, which leads to poor visual effect of the fingerprint identification module and affects the appearance of the electronic device. Contents of the invention [0003] Embodiments of the present invention provide a method for manufacturing a cover plate of a fingerprint recognition module, a cover plate of a finge...
