  • Capacitive fingerprint sensor
    Patent number: 10366270
    Abstract: Embodiments of the present disclosure provide a capacitive fingerprint sensor. The capacitive fingerprint sensor includes: a first electrode plate layer, a second electrode plate layer and a third electrode plate layer that are sequentially arranged. The first electrode plate layer forms a fingerprint capacitor with a finger, at least one fourth electrode plate layer is arranged between the first electrode plate layer and the second electrode plate layer, a first parasitic capacitor is formed between the first electrode plate layer and the fourth electrode plate layer, and a second parasitic capacitor is formed between the second electrode plate layer and the fourth electrode plate layer; and the capacitive fingerprint sensor further comprises an integrator having an integrating capacitor, and the integrating capacitor is formed between the second electrode plate layer and the third electrode plate layer.
