Abstract

Disclosed is a display module that includes at least one antenna, for use in an electronic device. The display module includes a display panel, and a magnetic sheet disposed under the display panel. The at least one antenna is disposed above the magnetic sheet. The magnetic sheet may serve to prevent degradation of electronic device performance by preventing the generation of eddy currents on a nearby metal part of the device.

Claims

1. A display module comprising:

a display panel;

a magnetic sheet disposed under the display panel; and

at least one antenna disposed above the magnetic sheet.

2. The display module of claim 1, wherein the antenna is disposed under the display panel.

3. The display module of claim 2, wherein the antenna includes a flexible printed circuit board (FPCB).

4. The display module of claim 1, further comprising a heat-dissipation sheet disposed under the display panel.

5. The display module of claim 4, wherein the magnetic sheet is disposed between the antenna and the heat-dissipation sheet.

6. The display module of claim 4, wherein the heat-dissipation sheet is disposed between the antenna and the magnetic sheet.

7. The display module of claim 4, wherein the heat-dissipation sheet includes graphite.

8. The display module of claim 1, wherein the antenna is disposed above the display panel.

9. The display module of claim 1, wherein the antenna includes indium tin oxide (ITO).

10. The display module of claim 9, further comprising a touch panel disposed above the display module, wherein the antenna is included in the touch panel.

11. The display module of claim 1, further comprising a noise-shielding sheet disposed under the magnetic sheet.

12. The display module of claim 1, further comprising a touch panel disposed above the display panel.

13. The display module of claim 1, further comprising a digitizer disposed under the display panel.

14. The display module of claim 13, further comprising a metal sheet for the digitizer disposed under the digitizer.

15. The display module of claim 1, wherein the display panel includes at least one of a thin film transistor liquid crystal display (TFT LCD) panel, a passive-matrix organic light-emitting diode (PM-OLED) panel, and an active-matrix organic light-emitting diode (AM-OLED) panel.

16. The display module of claim 1, wherein the magnetic sheet includes ferrite.

17. A display module comprising:

a display panel;

an antenna sheet disposed under the display panel and including at least one antenna; and

a composite sheet disposed under the antenna sheet and having different physical or chemical properties according to a combination of various materials to provide a plurality of functions.

18. The display module of claim 17, wherein the composite sheet has a metallic property.

19. The display module of claim 17, wherein the composite sheet has a magnetic property for inducing a magnetic field generated from the antenna sheet.

20. The display module of claim 17, wherein the composite sheet has a heat-dissipation property for uniformly diffusing heat generated by the display module.

21. The display module of claim 17, wherein the composite sheet shields electromagnetic noise.

22. The display module of claim 17, wherein the composite sheet absorbs external impact.

23. The display module of claim 17, further comprising a touch panel disposed above the display panel.

24. The display module of claim 17, further comprising a digitizer disposed between the display panel and the composite sheet.

25. An electronic device comprising:

a component mounting plate including at least one metal part;

a display module disposed on the component mounting plate; and

a main circuit board disposed under the component mounting plate and electrically connected to the display module;

wherein the display module includes an antenna configured by one or more laminated elements.
