Abstract

An example provides an apparatus including a display panel, a shielding layer including an opening adjacent to a back side of the display panel, and an antenna overlapping the opening to allow for wireless communication with the apparatus from a front side of the display panel.

Claims

1. An apparatus comprising:

a display panel;

a shielding layer having an opening, adjacent to a back side of the display panel; and

an antenna overlapping the opening and adjacent to the back side of the display panel to allow for wireless communication with the apparatus from a front side of the display panel.

2. The apparatus of claim 1, wherein the display panel is a touch screen display panel.

3. The apparatus of claim 1, further comprising a touch sensor panel adjacent to the panel.

4. The apparatus of claim 1, wherein the antenna is a near field communication antenna to allow for near field communication with the apparatus from the front side of the display panel.

5. The apparatus of claim 1, wherein the apparatus is a selected one of a desktop computer, a laptop computer, a handheld computer, a tablet computer, a netbook computer, a convertible computer, a display device, a server, a set-top box, a digital recorder, a game console, a smart phone, a personal digital assistant, a mobile phone, a digital media player, a television, or a digital camera.

6. A computing system comprising:

a system circuit board;

a display including a display panel and a shielding layer adjacent to a first portion of a back side of the display panel; and

an antenna adjacent to a second portion of the back side of the display panel such that the antenna is disposed between the display and the system circuit board to allow for wireless communication with the computing system from a front side of the display panel.

7. The computing system of claim 6, further comprising a housing to house the system circuit board, the display, and the antenna.

8. The computing system of claim 6, wherein the system circuit board is a motherboard.

9. The computing system of claim 6, wherein the display panel is a touch screen display panel and wherein the system circuit board is a touch screen controller.

10. The computing system of claim 6, wherein the second portion of the back side is within a periphery of the display panel.

11. The computing system of claim 6, wherein the second portion of the back side is on an edge of the display panel.

12. The computing system of claim 6, wherein the system is a selected one of a desktop computer, a notebook computer, a handheld computer, a tablet computer, a netbook computer, a convertible computer, a display device, a server, a set-top box, a digital recorder, a game console, a smart phone, a personal digital assistant, a mobile phone, a digital media player, a television, or a digital camera.

13. A method for making an apparatus, comprising:

coupling an antenna to a display panel having a shielding layer with an opening adjacent to a back side of the display panel, such that the opening is between the antenna and the display panel to allow for wireless communication with the apparatus from a front side of the display panel.

14. The method of claim 13, further comprising forming an opening in the shielding layer, and coupling the shielding layer to the back &

de of the display panel.

15. The method of claim 13, further comprising after the coupling, housing the antenna, the shielding layer, and the display panel in a housing with a system circuit board such that the antenna is between the system circuit board and the back side of the display panel.
