Abstract
A fingerprint detecting apparatus includes a plurality of fingerprint sensor devices. Each of the plurality of fingerprint sensor devices includes a first conductive layer in which a sensing electrode configured to receive a response signal from a subject according to application of a driving voltage is formed, a shield layer formed under the first conductive layer, and to which a ground potential is applied, a second conductive layer formed under the shield layer, a third conductive layer formed in a part under the second conductive layer, a gain controller formed between the second conductive layer and the third conductive layer, and configured to selectively vary again, and an amplifier configured to generate an output signal formed by amplifying the response signal as much as the gain. The response signal and the output signal are received and output independently from an adjacent fingerprint sensor device.
