Abstract

An antipollution film of a fingerprint module disclosed in the invention comprises a primer layer, a middle coating layer and a finish layer. The middle coating layer is formed on the primer layer. The finish layer is formed on the middle coating layer, the finish layer contains an anti-fingerprint reagent, the primer layer and the finish layer are transparent structures, and the middle coating layer is an opaque structure. The finish layer of the antipollution film contains the anti-fingerprint reagent, so the antipollution film has an anti-fingerprint function; and the primer layer and the middle coating layer are arranged between the finish layer and the surface of the fingerprint identification sensor of the fingerprint module, so the adhesion force of the finish layer adhered to the fingerprint identification sensor is improved, and the middle coating layer which is the opaque structure provides a required color for the antipollution film. The invention also discloses the fingerprint module, and a production method of the antipollution film.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to an antifouling film, a fingerprint module and a preparation method of the antifouling film. Background technique [0002] When the user puts the finger on the fingerprint module for fingerprint identification, the moisture and oil stains on the finger will generally adhere to the fingerprint module, resulting in a decrease in the accuracy of fingerprint identification by the fingerprint module, thereby affecting the use of the fingerprint module. Contents of the invention [0003] Embodiments of the present invention provide an antifouling film, a fingerprint module, and a method for preparing the antifouling film. [0004] The antifouling film of the fingerprint module according to the embodiment of the present invention, the antifouling film includes a primer layer, a middle paint layer and a top paint layer. The intermediate paint layer is formed on the p...
