EHF enabled display systems
Display systems that use contactless connectors for transmitting data are provided. The contactless connectors are electromagnetic connectors that form an electromagnetic communications link. The electromagnetic communications link can be established within different locations of the same device, or between two different devices. The communications link can be established using at least two transceivers. The transceivers can be incorporated in different enclosures that are hinged together, or the transceivers can be incorporated within a hinge that enables two enclosures to move with respect to each other. A transceiver can be incorporated into a display device that can receive data from an active surface that has a transceiver. When the display device is placed on the active surface, the display device may serve as an access point to content contained within the active surface.
1. A display apparatus for contactless use with an active surface apparatus, the contactless display apparatus comprising:
a display;
display controller coupled to the display; and
at least one extremely high frequency (EHF) transceiver coupled to the display controller, wherein the at least one EHF transceiver receives data from the active surface apparatus via a close proximity coupling that exists when the contactless display apparatus and the active surface apparatus are separated by no greater than a threshold distance, wherein the display activates when the display apparatus is placed in proximity of the active surface apparatus, and wherein the received data is processed by the display controller for presentation on the display; and
a processor operative to:
transmit access credentials to the active surface apparatus via the at least one EHF transceiver; and
receive content via the at least one EHF transceiver that is commensurate with the access credentials provided to the active surface apparatus.
2. The display apparatus of claim 1 , wherein the at least one EHF transceiver comprises at least two EHF transceivers.
3. The display apparatus of claim 1 , further comprising:
a user interface, wherein user interface commands are transmitted to the active surface apparatus via the at least one EHF transceiver.
4. The display apparatus of claim 1 , further comprising:
authentication circuitry that identifies the contactless display apparatus to the active surface apparatus.
5. The display apparatus of claim 4 receives data commensurate with the identity provided to the active surface apparatus.
6. The display apparatus of claim 1 , further comprising a power source operative to independently provide power to the display, display controller and the at least one EHF transceiver.
7. The display apparatus of claim 1 , further comprising power circuitry for receiving power from a remote power source, wherein the power transfer circuitry is operative to provide received power to the display, display controller and the at least one EHF transceiver.
8. The display apparatus of claim 7 , wherein the power circuitry wirelessly receives power from the remote power source.
9. The display apparatus of claim 1 , wherein the display, the display circuitry, and the at least one EHF transceiver reside on a flexible substrate.
10. The display apparatus of claim 1 , further comprising a user interface, wherein a user can navigate through content available on the active surface apparatus using the user interface.
11. The display apparatus of claim 1 , further comprising user interface circuitry that processes user interface events and provides user interface event data to the at least one EHF transceiver, which transmits the user interface data to the active surface apparatus via a close proximity coupling.
12. The display apparatus of claim 11 , wherein the user interface data is selected from the group consisting of audio data, video data, touch event data, and combination thereof.
13. The display apparatus of claim 3 , wherein the user interface comprises a touch screen user interface and fingerprint scanner.
14. The displays apparatus of claim 2 , wherein a distance between any two immediately adjacent EHF transceivers is less than 5 centimeters.
15. The display apparatus of claim 14 , wherein the distance is less than 1 centimeter.
