Abstract
The present disclosure provides a fingerprint recognition driving method for a display panel, the display panel including a fingerprint recognition circuit, a fingerprint recognition driving circuit and a controller, the fingerprint recognition driving circuit being used to provide a fingerprint recognition driving signal to the fingerprint recognition circuit, the fingerprint recognition driving method including: periodically arranging, by the controller, time periods for display and touch in a case that the controller does not receive a fingerprint recognition start signal; periodically arranging, by the controller, time periods for display and touch and time periods for fingerprint recognition at intervals in a case that the controller receives the fingerprint recognition start signal; generating, by the controller, a first fingerprint recognition reset signal during at least one time period for display and touch, and the fingerprint recognition driving circuit being reset under the control of the first fingerprint recognition reset signal.
