Abstract

Provided is an electronic device comprising a display module including a display area on which an image is displayed and a non-display area adjacent to the display area, a lower module disposed below the display module to support the display module, a signal radiation pattern, wherein an opening for radiating an antenna signal to an outside is defined in the signal radiation pattern and disposed to overlap the non-display area in the display module, a signal transmission pattern disposed between the display module and the lower module to radiate the antenna signal toward the signal radiation pattern, and an antenna controller disposed below the lower module to provide the antenna signal to the signal transmission pattern.

First claim

What is claimed is:

1. An electronic device comprising:
a display module including a display area on which an image is displayed and a non-display area adjacent to the display area;
a lower module disposed below the display module to support the display module;
a signal radiation pattern, wherein an opening is defined in the signal radiation pattern and configured to radiate an antenna signal to an outside and disposed to overlap the non-display area in the display module;
a signal transmission pattern disposed between the display module and the lower module to radiate the antenna signal toward the signal radiation pattern; and
an antenna controller disposed below the lower module to provide the antenna signal to the signal transmission pattern.

2. The electronic device of claim 1 , wherein the signal transmission pattern is electrically insulated from the signal radiation pattern.

3. The electronic device of claim 2 , wherein the signal transmission pattern is spaced apart from the signal radiation pattern.

4. The electronic device of claim 1 , wherein the opening has a rectangular shape extending along the non-display area.

5. The electronic device of claim 4 , wherein, if a length of the rectangular shape of the opening is referred to as an opening length, the opening length corresponds to a wavelength of the antenna signal.

6. The electronic device of claim 5 , wherein when the wavelength of the antenna signal is λ, the opening length is λ.

7. The electronic device of claim 5 , wherein when the wavelength of the antenna signal is λ, the opening length is λ/2.

8. The electronic device of claim 4 , wherein the opening includes a plurality of openings, and
each of the plurality of openings is spaced apart from each other.

9. The electronic device of claim 8 , wherein the plurality of openings are spaced apart from each other along the non-display area.

10. The electronic device of claim 1 , wherein the display module includes:
a display element layer having a light emitting element; and
a circuit element layer disposed below the display element layer to drive the light emitting element,
wherein the light emitting element includes:
a first electrode electrically connected with the circuit element layer;
a light emitting layer disposed on the first electrode; and
a second electrode disposed on the light emitting layer, and
wherein the signal radiation pattern includes a same material as the second electrode.

11. The electronic device of claim 10 , wherein the non-display area includes a first non-display area and a second non-display area,
the first non-display area is disposed between the display area and the second non-display area,
the second non-display area is an area on which an electrode of the circuit element layer, the first electrode, and the second electrode are not disposed, and
the signal radiation pattern overlaps the second non-display area.

12. The electronic device of claim 1 , wherein the signal radiation pattern further includes a peripheral pattern disposed adjacent to the opening, and
the peripheral pattern comprises a plurality of meshes.

13. The electronic device of claim 1 , further comprising an external case configured to accommodate the display module and the lower module,
wherein the signal radiation pattern contacts the external case.

14. The electronic device of claim 13 , wherein the signal radiation pattern further includes a peripheral pattern adjacent to the opening, and
the opening is surrounded by the peripheral pattern and the external case.

15. The electronic device of claim 1 , wherein the signal transmission pattern overlaps the signal radiation pattern on a plane.

16. The electronic device of claim 1 , wherein the signal transmission pattern is not in overlap with the signal radiation pattern on a plane.

17. The electronic device of claim 1 , wherein, when the non-display area extends in a second direction, the signal transmission pattern has a rectangular shape extending in a first direction crossing the second direction, and
when a length in the first direction of the signal transmission pattern is referred to as a transmission pattern length, the transmission pattern length corresponds to a length of a wavelength of the antenna signal.

18. The electronic device of claim 17 , wherein the signal transmission pattern includes a plurality of signal transmission patterns, and
the signal transmission patterns are spaced apart from each other in the second direction.

19. The electronic device of claim 1 , further comprising:
a metal layer disposed below the lower module; and
a connection electrode configured to electrically connect the signal transmission pattern and the antenna controller through a hole passing through the lower module and the metal layer,
wherein the signal transmission pattern receives the antenna signal from the antenna controller through the connection electrode.

20. The electronic device of claim 1 , further comprising a metal layer disposed below the lower module,
wherein the antenna controller is disposed below the metal layer and electrically connected with the metal layer, and
the signal transmission pattern receives the antenna signal from the antenna controller through coupling with the metal layer.
