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.

First claim

What is claimed is:

1. A display module comprising:
a display panel configured to display images that are visible from above the display module;
a magnetic sheet disposed under a first portion of the display panel at a location overlaying at least a central region of the display module;
a noise-shielding sheet disposed under the magnetic sheet;
at least one transparent Near Field Communication (NFC) antenna disposed above the magnetic sheet; and
a heat dissipation sheet is disposed under a second portion of the display panel adjacent to at least one side of the at least one transparent NFC antenna.

2. The display module of claim 1 , wherein the at least one transparent NFC antenna includes a flexible printed circuit board (FPCB).

3. The display module of claim 1 , wherein the heat-dissipation sheet includes graphite.

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

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

6. The display module of claim 5 , further comprising a metal sheet for the digitizer disposed under the digitizer.

7. 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.

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

9. A display module comprising:
a display panel configured to display images that are visible from above the display module;
an antenna sheet disposed under a first portion of the display panel at a location overlaying at least a central region of the display module and including at least one transparent Near Field Communication (NFC) antenna within the central region of the display panel;
a heat dissipation sheet is disposed under a second portion of the display panel adjacent to at least one side of the antenna sheet;
a magnetic sheet disposed under the antenna sheet; and
a noise-shielding sheet disposed under the magnetic sheet.

10. The display module of claim 9 , further comprising a digitizer disposed under the display panel.

11. The display module of claim 9 , further comprising a laminate layer at the top of the display module.

12. An electronic device comprising:
a housing;
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 a display panel, an antenna sheet having a transparent Near Field Communication (NFC) antenna formed in a pattern within a central region of the display panel, a magnetic sheet, a noise-shielding sheet, and a heat dissipation sheet, and

wherein,
the antenna sheet is disposed underlaying a first portion of the display panel at a location overlaying at least the central region of the display module within the housing;
the heat dissipation sheet is disposed underlaying a second portion of the display panel adjacent to at least one side of the antenna sheet,
the magnetic sheet is disposed under the antenna sheet; and
the noise-shielding sheet is disposed under the magnetic sheet.

13. The electronic device of claim 12 , wherein the heat dissipation sheet has a first portion disposed adjacent to the antenna sheet and a second portion disposed adjacent to the magnetic sheet.
