Abstract

The invention provides a fingerprint recognition device easy to rework. The fingerprint recognition device comprises a cover plate, a light-blocking layer, a gel layer, a protective layer and a fingerprint recognition element. The cover plate, the light-blocking layer, the gel layer and the protective layer are successively laminated. The fingerprint recognition element is coated by the protective layer. The protective layer does not dissolve in an organic solvent. Compared with the prior art, the fingerprint recognition device is not susceptible to damage during the reworking process. Therefore, the reworking efficiency is greatly improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to a fingerprint identification device. Background technique [0002] Fingerprint identification devices have been widely used in the electronic field. A common fingerprint identification device usually sticks a fingerprint identification element on a cover plate of an electronic device. When manufacturing fingerprint recognition devices, some fingerprint recognition devices need to be reworked because the yield rate is not up to standard. A common rework method is to soak the fingerprint identification device with a chemical solution, so that the fingerprint identification element is separated from the cover plate. However, the above method is easy to damage the fingerprint recognition element. Contents of the invention [0003] In view of this, it is necessary to provide an easy-to-rework fingerprint identification device. The fingerprint identification device includes a cover plate, a light-shielding layer, a colloid laye...
