MOBILE DEVICE WITH HIGH-ACCURACY FINGERPRINT IDENTIFICATION

摘要

A mobile device with high-accuracy fingerprint identification includes a display panel, a transparent protection layer, and a fingerprint identification device. The transparent protection layer has one surface attached to the display panel. The fingerprint identification device is attached to the surface of the transparent protection layer for detecting a user fingerprint. The fingerprint identification device includes a flexible substrate, a fingerprint sensor, and a detector. The fingerprint sensor is disposed on the flexible substrate for sensing the user fingerprint to generate a fingerprint image. The detector is disposed on the flexible substrate and electrically connected to the fingerprint sensor for distinguishing a minute parasitic capacitance variation generated by the fingerprint sensor. A part of the flexible substrate arranged with the fingerprint sensor is closely attached to the transparent protection layer, and a part of the flexible substrate arranged with the detector is separately attached to the transparent protection layer.
