Abstract
Fingerprint recognition circuit, fingerprint recognition structure, fingerprint recognition device, display panel, and display device are provided. The circuit includes: a fingerprint recognition driving transistor; a first capacitor; a driving signal input terminal; and a sensing signal output terminal. The first capacitor has a terminal electrically connected to a gate of the fingerprint recognition driving transistor and another terminal electrically connected to a ground. The driving signal input terminal is electrically connected to an input terminal of the fingerprint recognition driving transistor. An output terminal of the fingerprint recognition driving transistor is electrically connected to the sensing signal output terminal.
