"Generally, wall-mounted TVs are set up (on) the upper part of a wall spaced apart from the floor of a room. In such cases, the power line connected to the wall-mounted TV may be exposed, which may degrade the aesthetics of the TV," the patent, made public on the WIPO's website, said. "To solve this problem, a wireless power transmission method for wirelessly supplying power to the wall-mounted TV is being developed."
