Abstract:
A driving method and a driving device of a display panel and a display apparatus are provided. The driving method includes: loading, within a fingerprint recognition phase (t), a plurality of operating signals to a plurality of operating signal leads (20) connected to a gate driving circuit (200), each operating signal (VGH_G) including first level signals and second level signals which are loaded alternately, and a time that the operating signal (VGH_G) switches between the first level signal and the second level signal being a switching time; and loading, within the fingerprint recognition phase (t), a plurality of fingerprint pulse signals to a plurality of fingerprint scanning leads (30), respectively, and for any fingerprint scanning lead (30), a time when the fingerprint scanning lead is loaded with a fingerprint pulse signal and is in an active level state does not overlap with the switching time.
