Abstract:
A biometric recognition apparatus includes a substrate, a plurality of sensing electrodes, a plurality of traces, at least one shielding electrode, at least one insulating layer, and at least one fingerprint recognition IC. The sensing electrodes are arranged on one side of the substrate with at least one row to detect fingerprint information. Each trace is electrically coupled to at least one sensing electrode. The shielding electrodes are arranged above the traces to avoid the interference from fingers or external noise. The insulating layer is arranged between the shielding electrodes and the traces. The fingerprint recognition IC is connected to the corresponding sensing electrodes to detect the electric charge variations at the sensing electrodes.
