Abstract

The disclosure provides a display panel and a display apparatus, and belongs to the field of display technology. The display panel includes a display backplane and an antenna structure; the display panel further includes a frequency selective surface on a side of the antenna structure close to a light exit surface of the display panel; 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.

Claims (21)

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.

2. The display panel according to claim 1 , wherein the display panel has a display area and a peripheral area surrounding the display area; the antenna structure is on a side of the display backplane close to the light exit surface, and at least a part of the antenna structure is in the display area.

3. The display panel according to claim 1 , further comprising a dielectric layer between the frequency selective surface and the antenna structure.

4. The display panel according to claim 3 , wherein the dielectric layer has a thickness greater than 100 μm.

5. The display panel according to claim 3 , wherein the dielectric layer comprises a first transparent bonding layer, a transparent display substrate layer, and a second transparent bonding layer, which are stacked together.

6. The display panel according to claim 1 , further comprising a reflective electrode on a side of the display backplane away from the light exit surface of the display panel; and the reference electrode is connected to the reflective electrode.

7. The display panel according to claim 1 , wherein the microstrip line comprises a mesh structure.

8. The display panel according to claim 1 , wherein the frequency selective surface comprises a planar structure or a mesh structure.

9. The display panel according to claim 1 , wherein the display backplane comprises any one of a liquid crystal display backplane, an organic light-emitting diode display backplane, a quantum dot light-emitting diode display backplane or a quantum dot backlight display backplane.

10. A display apparatus, comprising the display panel according to claim 1 .

11. The display apparatus according to claim 10 , wherein the display panel has a display area and a peripheral area surrounding the display area; the antenna structure is on a side of the display backplane close to the light exit surface, and at least a part of the antenna structure is in the display area.

12. The display apparatus according to claim 10 , wherein the display panel further comprises a dielectric layer between the frequency selective surface and the antenna structure.

13. The display apparatus according to claim 12 , wherein the dielectric layer has a thickness greater than 100 μm.

14. The display apparatus according to claim 12 , wherein the dielectric layer comprises a first transparent bonding layer, a transparent display substrate layer, and a second transparent bonding layer, which are stacked together.

15. The display apparatus according to claim 10 , wherein the display panel further comprises a reflective electrode on a side of the display backplane away from the light exit surface of the display panel; and the reference electrode is connected to the reflective electrode.

16. The display apparatus according to claim 10 , wherein the microstrip line comprises a mesh structure.

17. The display apparatus according to claim 10 , wherein the frequency selective surface comprises a planar structure or a mesh structure.

18. The display apparatus according to claim 10 , wherein the display backplane comprises any one of a liquid crystal display backplane, an organic light-emitting diode display backplane, a quantum dot light-emitting diode display backplane or a quantum dot backlight display backplane.
