Reason claims it can wirelessly power an entire TV

No longer does a large TV need an even bigger home entertainment center to support it thanks to the hidden wall mounts, but you still have to manage wires. You can either route them through the wall so that they are out of sight or cross your fingers so that fully wireless television technology demonstrated at CES 2021 is legitimate.

If you’re really obsessed with keeping the wires out of sight, you can go for a smart TV that handles wireless streaming on its own, or you can use a wireless HDMI solution that allows game consoles to be connected to a screen without physical cable. But to this day, no one has found a way to eliminate the power cord from a television. Companies like It is demonstrated wireless power technologies that can power devices like TV remotes, store price signage and even charge a smartphone across a room, but the technology doesn’t have enough power to power the large televisions most people have in the home now.

But a Russian startup called Reasonance claims to have found a way to finally cut the last cord and showcased a prototype wireless TV using its technology at virtual CES 2021. Instead of a cord and a power outlet, the prototype TV has a receiver coil on the back and a transmitter coil nearby. The technology works similar to Qi wireless charging stations 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%, this which reduces wasted energy in the process.

The prototype of the technology shown at CES 2021 doesn’t quite look good – few of us would trade a thin power cord for a giant spool on a nearby table and a matching spool hanging from the back of our TVs. But Reasonance says 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 hanging TV (alignment coils doesn’t have to be completely perfect either) while the receiver coil could be integrated into the screen frame. This would potentially limit the thinness of a TV, but it appears to be minor compromise for the convenience of the screen being completely wireless.

Do we 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 patents worldwide in the United States, Canada, China, India, and South Korea, so it is apparently very confident in what it has created. . But we’ve seen other companies go after killing the power cord as well, including well-resourced companies like Samsung which patented its own approach to wireless TVs in early 2019, but has yet to deliver the technology in a consumer-ready product. A functional technical demonstration is one thing: a product that works reliably, safely and efficiently in the real world is quite another thing. Hwith optimism, Reasonance is soon in a position to take its technology to the next level.
