    Samsung patents world's first wire-less TV
    Having recently introduced the One Connect Box to their recent high end TVs such as the Q900R, Samsung look to be going one step further in getting rid of cables completely.
    The South Korean electronics giant have long been at the forefront of TV innovations and their recent move towards aesthetically pleasing models such as the Frame and Serif, and the addition of the One Connect Box - into which all your peripherals can be connected and which provides the power, leaving only a single discrete cable to the TV - all point to a future where the functionality that the consumer expects is presented in a clean, almost invisible, package that does not detract from the environment. And in the case of the Frame, typically hung on a wall, Samsung are hoping it actually adds to the space.

    In pursuit of these goals, Samsung’s next step appears to be to lose any remaining cables and it has been quietly working away on a solution involving a wireless power transceiver.

    In March 2018, Samsung Electronics filed a patent with the WIPO (World Intellectual Property Office) for both a wireless power transceiver and associated display equipment. Now, a year later, the method by which Samsung hopes to revolutionise home AV has been described and published.

    Sending electricity wirelessly is not a new concept and it would usually be achieved by using a wide coil. The implementation of this coil runs into an existing design aesthetic, that of ultra-thin panels, so any solution has to find a way to deal with the lack of space to house such a wide coil.

    The patent’s solution appears to be a bar, resembling a soundbar, mounted horizontally to the rear of the television. It’s this bar, which contains a groove in the middle for the solenoid coil, which is the heart of the power transceiver. A separate power transmitter (perhaps plugged in across the room) would then transmit magnetic signals creating power once these forces hit the solenoid in the receiving bar.

    Previous attempts at wireless power have been hampered by limitations in the distance the signal can be transmitted effectively and it’s not known whether Samsung’s patent completely addresses this limitation.

    Other advantages would be the safety element, in so much as receiving an electric shock would be a thing of the past and the risk from a short leading to a fire would be mitigated.

    As with all R&D developments moving from idea to paper to product will involve testing and refining, so don’t expect a wirelessly powered TV to hit the shelves anytime soon but it does mean that Samsung may well have a surprise or two to unveil at upcoming electronics shows such as CES or IFA over the next year or two.
