Engadget reports Fujitsu demonstrated a completely wireless LCD display at CeBIT. The data stream is handled via wireless USB and wireless power is provided by a technology called SUPA. In its current incarnation, SUPA can deliver around 25W of power over wide surface areas like a desk.
It's still a prototype though, Engadget noticed there were still some quirks.
he imagery is handled via wireless USB and can connect to any appropriately-equipped PC, while the juice is sucked in using a newly-minted proposed standard for wireless power delivery called SUPA (developed with the likes of Fraunhofer) that can function over wide surface areas -- in this case, an entire desk. Right now it's just the display, but it's easy to imagine how phones, laptops, tablets, and anything else that requires continuous power or a quick, convenient recharge could benefit from this arrangement rather than needing a special mat (which is, of course, corded) lying around.
