Abstract
A sensor for detecting a fingerprint, a fingerprint identification apparatus and a controlling method of a sensor for detecting a fingerprint are provided. The sensor for detecting the fingerprint includes a detecting panel including: a detecting region with a plurality of detecting units, in which the plurality of detecting units are distributed in a plurality rows and columns on the detecting region; and a conductive layer, configured to form a sensing capacitance between the conductive layer and a finger when the finger is close to the detecting region; a capacitance detecting module, configured to detect the sensing capacitance; and a control module.
