Claim 0:
1. A display panel, comprising:
a plurality of light-emitting areas and a plurality of non-light-emitting areas, wherein the plurality of light-emitting areas are spaced apart from each other by the plurality of non-light-emitting areas,
a plurality of light-emitting elements each located in one of the plurality of light-emitting areas, wherein each of the plurality of light-emitting elements comprises an anode and a cathode arranged opposite the anode, and a light-emitting layer located between the anode and the cathode; and
a cover layer covering a light-emission side of each of the plurality of light-emitting elements,
wherein projections of the anode, the cathode, and the light-emitting layer of one light-emitting element of the plurality of light-emitting elements on the cover layer overlap with each other, and overlapping parts of the projections are all located in one of the plurality of light-emitting areas,
wherein the cover layer comprises a substrate and first dopants doped in the substrate, the first dopants are magnetic,
wherein the cover layer comprises a first section and a second section, wherein the first section is associated with the plurality of light-emitting areas and the second section is associated with the plurality of non-light-emitting areas in a direction perpendicular to a surface of the display panel, and
wherein in the first section, a doping concentration of the first dopants is a first concentration C1, and in the second section, a doping concentration of the first dopants is a second concentration C2, wherein C2≥C1>0, or wherein C2>0 and C1=0.
