Samsung files patent for completely wireless tv
It has been discovered that Samsung Electronics has filed a patent with the WIPO (World Intellectual Property Office) for a method to power a tv screen without the need for any wires at all. The patent (filed in March 2018) was published on February 28, 2019 and is for a wireless power transceiver that works inside a flat panel display.
The patent was found by website Lets Go Digital and the patent can be found here.
Samsung has been working on the wireless tv concept for a while, and its new flagship Q90R QLED screen uses just once cable - the One Connect box for all cable connections.
But a completley wire-free display is something else entirely.
Normally this could be made possible by using a wide coil. However, TVs have become so thin in the last decade that there is no room in the housing to implement a coil.
The patented Samsung television is equipped with a wireless power transceiver in the form of a bar, which is mounted horizontally behind the television. The wireless transceiver is magnetic and has a groove in the middle for the solenoid coil. In addition, the power transceiver is provided with a double coil, which is wound in opposite directions.
The power transceiver can function as a wireless power receiver to generate power through magnetic forces emitted by a separate wireless power transmitter. Speakers are also placed on both sides of the transceiver.
The wireless power receiver is connected to a separate box, where the wireless power transmitter is incorporated. It is configured so that it can generate a magnetic field at the power receiver. The box has the shape of a soundbar and should be placed within a certain distance from the television.
