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.
