1. A display panel, comprising a display backplane and an antenna structure, wherein the display panel further comprises a frequency selective surface on a side of the antenna structure close to a light exit surface of the display panel; and
the frequency selective surface is configured to transmit an electromagnetic wave with a specific frequency, so as to enhance a radiation gain of the antenna structure,
wherein the display panel has a display area and a peripheral area surrounding the display area; the antenna structure comprises a microstrip line and a reference electrode in a same layer as the microstrip line; the microstrip line is in the display area; and the reference electrode is at least partially in the peripheral area; and
a part of the reference electrode in the peripheral area is of a solid planar structure and connected to a ground line on a side of the display backplane through conductive gold balls in a sealant in the peripheral area.
