Abstract

An electronic device comprises: a fingerprint identification module; a protective cover plate comprising a protective layer and a protective layer, a decorative layer positioned on at least one surface of the protective layer; a first bonding layer located between the protective cover plate and the fingerprint identification module, so that the fingerprint identification module is attached to theprotective cover plate. The protective cover plate further comprises a second bonding layer, the second bonding layer is located between the decorative layer and the protective layer so as to achieveattachment of the decorative layer and the protective layer, and the elastic modulus of the second bonding layer is larger than that of the first bonding layer. And the connection strength between thedecorative layer and the second bonding layer is relatively high, so that the texture effect of the decorative layer can be kept, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of fingerprint imaging, in particular to an electronic device. Background technique [0002] Fingerprint recognition technology collects the fingerprint image of the human body through the fingerprint imaging sensor, and then compares it with the existing fingerprint imaging information in the fingerprint recognition system to realize identity recognition. Due to the convenience of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, especially consumer electronics such as personal computers and mobile phones. The adoption of fingerprint recognition technology can greatly improve the safety and convenience of electronic products. . [0003] On the other hand, in portable electronic devices represented by smart phones and tablet computers, in order to protect display devices such as liquid crystal panels, a transparent protective cover is usually prov...
