Samsung Patents Wireless TV With No Power Cable (techradar.com)
An anonymous reader quotes a report from TechRadar: Could Samsung be on the cusp of a fully wireless TV? A recent patent hints that a Samsung TV without any pesky cables could be around the corner. Spotted by LetsGoDigital, the patent was filed in March 2018 but only released publicly in late February of this year. The patent revolves around a wireless power transceiver, which would make the prospective television the first of its kind to transmit power across the room rather than relying on a power cable -- increasingly seen as an eyesore next to Samsung's premium design sets. The transceiver takes the form of a magnetic bar attached to the rear of the television, given that panels themselves are too thin to house anything of this kind. It would then require a separate power transmitter (plugged into the mains) to keep the TV running.
Wireless power of that wattage would also prevent any cell phones from working in a 2-block radius!
Added bonus!
My UID is prime and so is this number: 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0.
Patents are about as useful for predicting the future of consumer technology as reruns of The Jetsons. Just ask a Theranos investor.

So you'll get rid of the cord, and it'll need a clunky "base station" - which has a cord.
Sweet.
Makes the article about as useful as a wireless TV.
I wonder what kind of power losses a system like this will incur. IIRC, some of the best inductive charging systems lose at least 15% of their power to the ether.
Which is the least of my worries.
The power my current TV uses is pretty much non-existent compared to the 120 lb 32 in CRT it replaced.
I do wonder how HDMI, Ethernet (yeah I know) RCA, VGA, S-Video and Antenna are supposed to work 'wirelessly"
Unless there is another proprietary Samsung "Brick" that transmits to the TV,
In an era where we should be focusing on increasing efficiency so we can decrease our energy usage, why do humans keep inventing things that take more energy to do the same thing? I can understand the convenience of something like wireless smart phones, less so with streaming audio/video, and certainly el zilcho grande with wireless power. Not to mention (as others have) the unknowns of broadcasting hundreds of watts of power over the air.
Can we take the nidiots who patented this notion and replace them with more researchers looking into room-temperature superconductors so our electrical grid could be essentially lossless. Perhaps we (as humans) can collectively decide that convenience is not the do-all and end-all or our technological progress.
Just plug the damn TV into the wall and deal with it! Sheesh!
of a recent meme I saw. Supposedly from someone working in tech support and one of the things they've endured from those they support:
Yes, I need wireless comm and no, I won't be leaving my seat.
Is there some reason Samsung believes there is a need for wireless power other than aesthetics?
Imagine a sphere centered around the sender, whose surface lies on the recieving surface. The percentage of the sphere touching the receiving surface is what you'll be left with. The whole huge rest will be wasted.
In other words: The efficiency falls with the square of the distance.
This is of course simplified, since in theory, energy could also get reflected and still be used.
Plus, the medium (air, walls, fist tanks) also absorbs a bit.
And of course you can focus a tight beam and use frequencies where expected materials will be most transparent.
There will be a limit on the transmitted energy per bandwith too.
So yeah, to wasteful to not be totally iTarded.
Wireless power is good for things that you need to carry around. My TV sits in one place. And with very little effort I can route the cord where it can't be seen.
Have gnu, will travel.
Hopefully the patent means no other company will be stupid enough to want to do this now.
Quick, file a patent for a wireless power transceiver and an air blower, a wireless power transceiver and portable battery charging device, wireless power transceiver and microwave oven appliance, wireless powered alarm clock device, wireless electric heater system, wireless oven, etc...
You can also make wireless light bulbs by using the magnatron from a microwave. Very cool to watch however, there is a reason they use led and meshes in microwave ovens. I'll pass on the super cool wireless TV and stick to 4 inch power cables plugged in behind the TV where no one can see them anyway.
I dont see why people obsess over the wires... if you ask me the unsightly thing they should get rid of is the little blue flashlight on the front.
Oh boy, forget about flying to Mars with that fake Tesla wannabee who just hijacked his name. A Wardenclyffe tower in your room is the most exciting innovation we're all waiting for for power all our appliances.
...is a TV set with no power cord, no antenna port, no internet connection. In other words a brick...but marketing people will find people who will buy it!
Nikola Tesla would be glad that someone is using his idea yet upset that people would think this is a new idea.

Making a gadget wireless that is never moved from its location for years until it gets thrown away.
They'll steal it, possibly make it better, and sell for cheaper.
Is this like crystal radio television?
Or is this a wireless power transducer that'll give the next door neighbors cancer?
My TV draws 100 watts, I don't want 100 watts passing through my head to power the TV.
So, my father-in-law bought a very expensive "wireless" TV several years ago -- against my advice -- and it has been a particularly negative experience, overall. (Of course, the power wasn't actually wireless; rather, in his case, power was the one wire which still connected directly to the display panel... but that distinction is immaterial to my point.)
As soon as you decide to do everything wirelessly, you're introducing a series of new problems to the overall experience, such as latency and transmission interference. Latency means that the video signal takes long enough to reach the display, that the screen is almost entirely unusable for any kind of real-time video games, such as racing sims or FPS. (I observed this issue first hand while playing Mario Kart Wii; the Wii did not remain connected to that screen for very long.) And when -- not "if" -- transmission interference hits, that's even worse; the components have degraded over time, such that even with only a few feet between the "head unit" transmitter and the display, we ended up with random glitch-outs of the signal, growing more frequent over time.
So really, my Subject above is understating the severity of the issue... relying so heavily on wireless is more like solving one entirely noncritical aesthetics "problem" by introducing a series of potential deal-breaker technical problems. I would fully expect the same analysis to apply to this new "now, with even more wireless!" set from Samsung -- and I will be advising anyone who asks that they should stay far, far away from this hell-hound.
The new system will also make you sterile. That why you should never have your genitals between the power sender and the TV
