Abstract
Provided is a display panel including a base substrate, a display function film layer, a filter film layer, and a fingerprint recognition circuit. The display function film layer is disposed on the base substrate, and the display function film layer is provided with a plurality of light-emitting regions. The filter film layer is disposed on a side of the display function film layer away from the base substrate, wherein the filter film layer is capable of transmitting light emitted from the plurality of light-emitting regions, and a material of the filter film layer comprises a conductive material. The fingerprint recognition circuit is disposed on the base substrate, wherein the fingerprint recognition circuit is connected to the filter film layer, and configured for fingerprint recognition based on light reflected by an obstacle and received by the filter film layer.
