Abstract:
A biometric recognition apparatus with reflection-shielding electrode includes a substrate, a sensing electrode layer arranged on one side of the substrate, the sensing electrode layer including a plurality of sensing electrodes and at least one suppressing electrode. The biometric recognition apparatus further includes a plurality of selection switches and conductive wires, at least a part of the selection switches and the conductive wires are electrically connected to the sensing electrodes. The biometric recognition apparatus further includes a reflection-shielding electrode layer with at least one reflection-shielding electrode and arranged on one side of the sensing electrode layer. By incorporating the reflection-shielding electrode and the suppressing electrode, the sensing sensibility and signal to noise ration can be enhanced, thus increasing the sensing distance between sensing electrode and user finger.
