Abstract
Disclosed are a fingerprint identification structure, a driving method thereof and an electronic device. The fingerprint identification structure includes: a driving electrode layer; a piezoelectric material layer; a receiving electrode layer, which includes M receiving electrodes; an auxiliary driving electrode layer, which is located at the side of the piezoelectric material layer away from the receiving electrode layer, and is arranged in a layer different from the driving electrode layer; and a first insulating layer, the auxiliary driving electrode layer includes N auxiliary driving electrodes; the N driving electrodes and the N auxiliary driving electrodes are alternately arranged; and the orthographic projection, on the piezoelectric material layer, of an i-th auxiliary driving electrode overlaps with an interval between the orthographic projections, on the piezoelectric material layer, of an i-th driving electrode and an (i+1)-th driving electrode.
