Fingerprint pixel sensor array on a display

Abstract

The fingerprint pixel sensor array was investigated for the application to the mobile phone. For the fingerprint sensing high resolution pixel array is necessary. Therefore, the readout voltage dependence on the resistance of the wires was investigated after composing 450th pixel array. The readout voltage was investigated for the ridge contact and valley contact. The simulated results show that the transparent electrode wire can be applied for the fingerprint pixel sensor array.
