A large TV no longer needs an even larger home entertainment center to support it due to the hidden wall mounts, but you still have to take care of the wires. You can either direct them through the wall so that they are not visible or cross your fingers that this fully wireless TV technology demonstrated at CES 2021 it is legitimate.
If you’re really obsessed with wires that can’t be seen anymore, you can opt for a smart TV that manages wireless streaming on your own, or use a wireless HDMI solution that lets you connect your game console to a physical wireless screen. . But so far, no one has found a way to remove the power cord of a TV. Companies like This is they have proven wireless power technologies which can power devices such as TV remote controls, in-store price signage and even charge a smartphone over a room, but technology doesn’t have enough of a boost to power the big TVs most people have at home now.
But a Russian startup called Reasonance claims to have found a way to finally cut the last cable and demonstrated a prototype wireless TV using its technology at virtual CES 2021. Instead of a cable and an electrical outlet, the TV prototype has a receiving coil on the back and a transmitting coil nearby. The technology works similarly to wireless Qi charging buffers, where a current is induced by a magnetic field, but Reasonance claims that its implementation increases energy efficiency from 75% for the best induction chargers to 90%, so more is lost. little energy in the process.
The prototype of the technology demonstrated at CES 2021 is not exactly aesthetically pleasing – few of us would change a thin power cable for a giant coil on a nearby table and a suitable coil hanging on the back of our TVs. But Reasonance claims that its wireless power transfer can operate at distances of up to 3.3 feet, allowing the transmitter coil to be hidden inside the wall behind a suspended TV (the coil alignment doesn’t have to be completely perfect either) while the coil the receiver could be integrated into the display. It would potentially limit how thin a TV could be, but that seems minor compromise for screen comfort being completely wireless.
Do we want to believe that completely wireless TVs are right around the corner thanks to Reasonance? Yes, of course. The startup has already patented its technology in Russia and is currently applying for patents around the world in the US, Canada, China, India and South Korea, so it is apparently very confident in what it has created. But we’ve also seen other companies kill power cord, including well-resourced companies like Samsung that patented its own approach to wireless TVs in early 2019, but has not yet provided the technology in a ready-to-eat product. A functional technical demonstration is one thing: a product that works reliably, safely and efficiently in the real world is something else entirely. HFortunately, Reasoning is soon able to take its technology to the next step.
