1. A display panel, comprising:
a display functional layer with a display side and a back side opposite to each other;
an antenna functional layer on the back side of the display functional layer, wherein the antenna functional layer comprises at least one antenna structure, and the at least one antenna structure comprises:
a first substrate,
a power receiving coil on a side, away from the display functional layer, of the first substrate, and
a first flat layer on a side, away from the first substrate, of the power receiving coil; and
a magnetic field absorption layer on a side, close to the display functional layer, of the antenna functional layer, or on a side, away from the display functional layer, of the antenna functional layer;
wherein an orthographic projection of the power receiving coil on a reference plane is within an orthographic projection of the magnetic field absorption layer on the reference plane, and the reference plane is a plane perpendicular to a thickness direction of the display panel.
