Abstract
A fingerprint sensor having electrostatic discharge (ESD) protection includes a first ESD protection electrode and a second ESD protection electrode. The first ESD protection electrode is connected to an ESD protection circuit for providing an ESD path, where the first ESD protection electrode and a fingerprint sensor electrode array are formed in a same layer of the fingerprint sensor. The second ESD electrode is connected to the first ESD electrode via multiple conductive via.
