Claim 0:
1. A display panel, comprising a plurality of display units, each of the display units having an active area for display and an induction area for identifying fingerprints, wherein the display unit comprises:
a substrate;
a planarization layer arranged on the substrate and comprising a first area and a second area, wherein the first area is opposite to the active area, and the second area is opposite to the induction area and is provided with a concave-convex structure;
a pixel unit arranged on the planarization layer and located in the first area; and
an induction electrode arranged on the planarization layer and covering a concave-convex surface of the concave-convex structure to extend along the concave-convex surface of the concave-convex structure, so as to improve capacitance with a finger of user in response that a fingerprint of the finger of the user covers the display panel, and output a signal so as to identify the fingerprint of the user through the output signal.
