Fingerprint identification module and mobile electronic device with same
10354112 · 2019-07-16 · ·

A fingerprint identification module is provided for identifying a fingerprint of a finger. The fingerprint identification module includes a sensing chip and a thermally deformable layer. The thermally deformable layer is disposed over the sensing chip and includes a sensing region. When the finger is placed on the sensing region, the fingerprint of the finger is sensed by the sensing chip. If the fingerprint identification result of the fingerprint identification module fails, the thermally deformable layer is firstly changed to a molten state and then returned to a solidified state within a predetermined time period. Consequently, the finger is fixed by the thermally deformable layer.
