Abstract

An electronic device includes: a display layer in which an active area and a peripheral area adjacent to the active area are defined, the display layer including a common electrode, a sensor layer disposed on the display layer and including a plurality of sensing electrodes and an antenna pattern, and a cover layer spaced apart from the sensor layer with the display layer therebetween, the cover layer having a conductivity. The peripheral area includes a first area and a second area spaced apart from the active area with the first area therebetween, and the common electrode is disposed in the active area and the first area and is spaced apart from the second area. When viewed in a plan view, a portion of the antenna pattern does not overlap the common electrode and overlaps the cover layer.

Claims (38)

1. An electronic device comprising:

a display layer in which an active area and a peripheral area adjacent to the active area are defined, wherein the display layer comprises a common electrode;

a sensor layer disposed on the display layer, wherein the sensor layer comprises a plurality of sensing electrodes and an antenna pattern comprising an antenna and an antenna line; and

a cover layer disposed under the display layer, wherein the cover layer has a conductivity,

wherein the peripheral area comprises a first area and a second area spaced apart from the active area with the first area therebetween,

the common electrode is disposed in the active area and the first area and is spaced apart from the second area,

when viewed in a plan view, the antenna pattern does not overlap the common electrode, and

when viewed in the plan view, the cover layer overlaps the antenna pattern and the common electrode, and when viewed in the plan view, an entire portion of the antenna and an entire portion of the antenna line does not overlap the common electrode,

the antenna is configured to radiate a frequency signal, and

the antenna line is configured to feed the antenna.

2. The electronic device of claim 1 , wherein

the antenna pattern comprises a first portion and a second portion adjacent to the first portion,

wherein the second portion has a mesh structure.

3. The electronic device of claim 2 , wherein the antenna pattern comprises a dipole antenna.

4. The electronic device of claim 1 , wherein

a groove is defined in the common electrode in a direction away from a side surface of the display layer, and

when viewed in the plan view, the antenna pattern is disposed in the groove and is spaced apart from the common electrode.

5. The electronic device of claim 1 , wherein a plurality of openings is defined in the common electrode.

6. The electronic device of claim 1 , wherein the second area has a width of about 300 μm or greater.

7. The electronic device of claim 1 , further comprising:

a protective layer disposed between the cover layer and the display layer.

8. The electronic device of claim 1 , wherein

when viewed in the plan view, the antenna pattern overlaps the active area and the peripheral area, and

a portion of the antenna pattern, which overlaps the active area, has a mesh structure.

9. An electronic device comprising:

a sensor layer comprising a plurality of sensing electrodes and an antenna pattern disposed in a same layer as some of the plurality of sensing electrodes;

a display layer disposed below the sensor layer, wherein the display layer comprises a common electrode and a plurality of pixels; and

a cover layer disposed below the display layer and having a conductivity,

wherein, when viewed in a plan view, the antenna pattern non-overlaps the common electrode and overlaps the cover layer;

wherein the antenna pattern comprises an antenna and an antenna line, and

wherein when viewed in the plan view, the cover layer overlaps the common electrode, and when viewed in the plan view, an entire portion of the antenna and an entire portion of the antenna line does not overlap the common electrode,

the antenna is configured to radiate a frequency signal, and

the antenna line is configured to feed the antenna.

10. The electronic device of claim 9 , wherein a distance between a side surface of the display layer and the common electrode is about 300 μm or greater.

11. The electronic device of claim 9 , further comprising:

a protective layer disposed between the cover layer and the display layer.

12. The electronic device of claim 1 , wherein at least some of the plurality of sensing electrodes and the antenna pattern are disposed in a same layer as each other.

13. The electronic device of claim 1 , wherein, when viewed in the plan view, the antenna pattern overlaps the second area.
