Abstract

In some examples, an apparatus includes a display panel, a shielding layer having an opening formed within a periphery of the shielding layer, the shielding layer adjacent to a back side of the display panel, and an antenna adjacent to the back side of the display panel, wherein the shielding layer is received in the opening formed in the shielding layer, and does not extend beyond an edge of the display panel 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 formed within a periphery of the shielding layer, the shielding layer adjacent to a back side of the display panel; and

an antenna adjacent to the back side of the display panel, wherein the antenna is received in the opening formed in the shielding layer, and does not extend beyond an edge 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 antenna sits inside the opening and touches the back side of the display panel.

3. The apparatus of claim 1, wherein the antenna is a radio interference shield between the display panel and a system circuit board of a computing system in which the display panel, the shielding layer, and the antenna are to be provided.

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

5. The apparatus of claim 1, further comprising a touch sensor panel adjacent to a front side of the display panel.

6. 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.

7. 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.

8. A computing system comprising:

a system circuit board;

a display including a display panel and a shielding layer having an opening formed within a periphery of the shielding layer, the 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, the antenna being physically disposed between the display and the system circuit board, and the antenna received in the opening and not extending beyond an edge of the display panel to allow for wireless communication with the computing system from a front side of the display panel, and the antenna being a radio interference shield between the display panel and the system circuit board.

9. The computing system of claim 8, wherein the antenna sits inside the opening and touches a sidewall of the opening.

10. The computing system of claim 8, further comprising a housing to house the system circuit board, the display, and the antenna.

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

12. The computing system of claim 8, wherein the display panel is a touch screen display panel, and wherein the system circuit board is a touch screen controller.

13. The computing system of claim 8, wherein the computing 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.

14. The computing system of claim 8, wherein the opening in the shielding layer provides a path through which the wireless communication with the apparatus from the front side of the display panel occurs.

15. A method for making an apparatus, comprising:

forming an opening in a shielding layer, the opening formed within a periphery of the shielding layer; and

coupling an antenna to a display panel having the shielding layer with the opening adjacent to a back side of the display panel, the shielding layer between the antenna and the display panel, the antenna not extending beyond an edge of the display panel, the antenna received in the opening to allow for wireless communication with the apparatus from a front side of the display panel.

16. The method of claim 15, wherein the antenna sits inside the opening and touches a sidewall of the opening.

17. The method of claim 15, further comprising coupling the shielding layer to the back side of the display panel.

18. The method of claim 15, further comprising housing the antenna, the shielding layer, and the display panel in a housing with a system circuit board, the antenna being a radio interference shield between the system circuit board and the display panel.
