1. A display panel, comprising:
a base;
a light-emitting structure on a side of the base;
a package layer on a side of the light-emitting structure facing away from the base;
a photoelectric sensing structure on a side of the package layer facing the base;
at least one of a touch functional layer or a color filter layer on a side of the package layer facing away from the base, wherein the touch functional layer comprises a first metal layer structure, a touch insulation layer and a second metal layer structure stacked in a normal direction of a plane where the base is located, and the color filter layer comprises a black matrix; and
a collimation light path structure on a side of the photoelectric sensing structure facing away from the base, the collimation light path structure comprising at least two light-blocking layers stacked in the normal direction of the plane where the base is located, wherein each of the at least two light-blocking layers has light-transmitting holes arranged in an array, and orthographic projections of the light-transmitting holes in different ones of the at least two light-blocking layers on the base at least partially coincide with each other, and the at least two light-blocking layers comprise at least one first light-blocking layer on a side of the package layer facing away from the base, and the at least one first light-blocking layer is disposed in the same layer as the first metal layer structure, the touch insulation layer, the second metal layer structure or the black matrix.
