Patent abstract
A fingerprint sensor having ESD protection has a body and an ESD protection circuit. The body has a fingerprint sensing electrode array and an ESD protection electrode providing an ESD protection to the fingerprint sensing electrode array. The ESD protection circuit is connected respectively to the ESD protection electrode, a high electric potential terminal and a low electric potential terminal. The ESD protection circuit provides a first static electricity discharge path to the high electric potential terminal, and a second static electricity discharge path to the low electric potential terminal. The fingerprint sensor provides two static electricity discharge paths, so that the fingerprint sensor has a better ESD protection.
