Abstract

Described herein are architectures, platforms and methods for integrating near field communication (NFC) coil antenna behind a screen display of devices and more particularly, to improve near field coupling capabilities of the devices by configuring the screen display to implement a context based software logo to guide a user. The context based software logo displays a tapping area location during NFC related functions. The NFC related functions include wireless power transfer (WPT) and/or near field communications (NFC) capabilities of the devices

Claims

1. A device comprising:

one or more processors;

a memory configured to the one or more processors;

a near field communications (NFC) antenna configured to the one or more processors, the NFC antenna integrated in a screen display of the device, the screen display configured to display a software based image that indicates a tapping area for a NFC transaction.

2. The device as recited in claim 1, wherein the NFC antenna is embedded between a front polarizer component and a color filter glass of the screen display.

3. The device as recited in claim 1, wherein the NFC antenna is embedded between the color filter glass component and a thin film transistor (TFT) glass of the screen display.

4. The device as recited in claim 1, wherein the NFC antenna, a ferrite, and the screen display are integrated into a single package.

5. The device as recited in claim 1, wherein the NFC antenna is positioned within an area defined by the screen display.

6. The device as recited in claim 1, wherein the NFC antenna is in a substrate that includes an invisible black matrix area of the screen display.

7. The device as recited in claim 1, wherein the screen display is one of a billboard or a car dashboard screen display.

8. The device as recited in claim 1, wherein the screen display includes in-plane switching (IPS), twisted nematic (TN), fringe field switching (FFS), vertical alignment (VA), or optically compensated bend-mode (OCB) display.

9. The device as recited in claim 1, wherein the NFC transaction is NFC communications, wireless power transfer (WPT), Europay MasterCard and Visa (EMV) transactions, or Microsoft®

Proximity Communications.

10. The device as recited in claim 1, wherein the device is one of an Ultrabook, a tablet computer, a netbook, a notebook computer, a laptop computer, a mobile phone, a cellular phone, a smartphone, a personal digital assistant, a multimedia playback device, a digital music player, a digital video player, a navigational device, or a digital camera.

11. A near field communications (NFC) antenna comprising:

a coil antenna integrated within a screen display of a device, the screen display configured to display a software based image that indicates a tapping area for a NFC transaction; and

an NFC module to provide tuning to the coil antenna.

12. The NFC antenna as recited in claim 11, wherein the coil antenna is embedded between a front polarizer component and a color filter glass component of the screen display.

13. The NFC antenna as recited in claim 11, wherein the coil antenna is embedded between a color filter glass component and a thin film transistor (TFT) glass component of the screen display.

14. The NFC antenna as recited in claim 11, wherein the NFC antenna, a ferrite material, and the screen display are integrated or fused into a single package.

15. The NFC antenna as recited in claim 11, wherein the NFC antenna is in a substrate that includes a black matrix area of the screen display.

16. The NFC antenna as recited in claim 11, wherein the screen display includes in-plane switching (IPS), twisted nematic (TN), fringe field switching (FFS), vertical alignment (VA), or optically compensated bend-mode (OCB) display.

17. The NFC antenna as recited in claim 11, wherein the NFC antenna is made out of a printed circuit board (PCB), a flexible printed circuit (FPC), a metal wire, created through a laser direct structuring (LDS) process, or directly embedded to the screen display.

18. A method of integrating a near field communications (NFC) antenna to a screen display of a device, the method comprising:

positioning the NFC antenna in an area that is covered by the screen display;

embedding the NFC antenna within components of the screen display; and

enabling a context based software logo during near field coupling, the context based software logo is configured to display a logo image that includes a tapping area location during the near field coupling.

19. The method as recited in claim 18, wherein the positioning of the NFC antenna includes the area in the screen display where the logo image is visible to a user.

20. The method as recited in claim 18, wherein the context based software logo is configured to display a current transaction that includes NFC communications, wireless power transfer (WPT), Europay MasterCard and Visa (EMV) transactions, or Microsoft®

Proximity Communications.
