FINGERPRINT DETECTING APPARATUSE AND METHOD FOR IMPROVING FINGERPRINT DETECTING

摘要

An embodiment of the present invention provides a fingerprint detection device, comprising: a sensor pad for fingerprint detection; and a bezel which is closely arranged to the sensor pad. A driving voltage is applied to the bezel. The fingerprint detection device comprises: a monitoring pad which is arranged in a sensor pad area and monitors an output voltage of the sensor pad by the driving voltage; and a compensation unit which compensates the output voltage of the sensor pad based on the size of a voltage sensed by the monitoring pad.
