Samsung Patents Wireless TV With No Power Cable (techradar.com)

An anonymous reader quotes a report from TechRadar: Could Samsung be on the cusp of a fully wireless TV? A recent patent hints that a Samsung TV without any pesky cables could be around the corner. Spotted by LetsGoDigital, the patent was filed in March 2018 but only released publicly in late February of this year. The patent revolves around a wireless power transceiver, which would make the prospective television the first of its kind to transmit power across the room rather than relying on a power cable -- increasingly seen as an eyesore next to Samsung's premium design sets. The transceiver takes the form of a magnetic bar attached to the rear of the television, given that panels themselves are too thin to house anything of this kind. It would then require a separate power transmitter (plugged into the mains) to keep the TV running.

    Wireless power of that wattage would also prevent any cell phones from working in a 2-block radius!

    Added bonus!

    So you'll get rid of the cord, and it'll need a clunky "base station" - which has a cord. Sweet.

    Which will *also* have the media cable (Coax/CAT) attached and *also* have to transmit the video and audio signals to the display. Won't it be fun to sit in the middle of that RF soup all night. Or... you could simply run the cables to a regular display inside the wall. This seems like a solution in search of a problem.

    You lose 15% when two large surface area near field "antennas" are in close proximity (compared to the size of the antenna). This is mostly magnetic resonance coupling. To actually transmit over large distances, the losses become much higher and more dangerous in that foreign objects could receive, conduct, and start bleeding power as heat like a metal handle on a take out box in your microwave. For these reasons there are very limited applications where sending appreciable power over long distances (yards/meters) is viable.

    No, we're supposed to waste all that energy with wireless power just so that people don't have to see a power cord hanging down from a television mounted on a wall.
