A large TV no longer needs an even larger home entertainment center to support it thanks to the hidden wall brackets, but you still have to deal with cables. You can route them through the wall so they are out of sight or cross your fingers that this completely wireless TV technology demonstrated at CES 2021 is legit.
If you’re really obsessed with cables that are out of sight, you can opt for a smart TV that can stream wirelessly on its own or use a wireless HDMI solution that allows game consoles to be connected to a display without a physical cable. But until now, no one has found a way to unplug a TV’s power cord. Companies love That is have shown wireless power technologies those devices like TV remotes, signs with prices in the store and even charge a smartphone from a room, but the technology doesn’t have enough kick to power the large TVs most people have at home now.
But a Russian start-up called Reasonance claims it found a way to finally cut the last cord and demonstrated a wireless TV prototype using its technology at the virtual CES 2021. Instead of a cord and a Wall outlet, the prototype of the tv has a receiver coil on the back and a head coil nearby. The technology works similar to the wireless Qi charging pads where a current is generated by a magnetic field, but Reasonance claims that its implementation increases energy efficiency from 75% for the best inductive chargers to 90%, so less power is wasted in the process.
The prototype of the technology showcased at CES 2021 isn’t exactly aesthetically pleasing – few of us would trade a flimsy power cord for a giant coil on a nearby table and a matching coil hanging from the back of our TVs. But Reasonance claims that the wireless power transmission can operate at distances of up to 1 meter, which allows the headpiece to be hidden in the wall behind a hanging TV (the alignment of the coils doesn’t have to be perfectly perfect either) while the receiver coil can be integrated into it. frame of the screen. It might limit how thin a TV could be, but that seems like a minor one tradeoff for the convenience of the screen being completely wireless.
Do we want to believe that fully wireless TVs are just around the corner thanks to Reasonance? Yes, of course we do. The startup has already patented its technology in Russia and is currently filing for patents around the world in the US, Canada, China, India and South Korea, so it appears to be very confident in what it was created. But we’ve seen other companies try to kill the power cord as well, including good-resource companies like Samsung that patented its own approach to wireless TVs in early 2019, but has yet to deliver the technology in a consumer-ready product. A working technical demo is one thing – a product that works reliably, safely and efficiently in the real world is quite another. H.favorable, Reasonance will soon be able to transfer its technology to that next step.
