    I was thinking that remote's have infrared and the TV has an infrared reciever, every one knows this.
    However how cool would it be if the TV was also capaple of IR?

    Thinking about how motion controls worked on the Wii for instance. You had to plug in that separate IR bar and put it over or under your TV.
    With IR built into the screen you would not have to have that bar.

    Or imagine the things you could do with the joycons that have IR cameras. For instance you could perfectly recalibrate them on the fly by sometimes flash IR in the corners of the TV.
    If this was a thing on computer monitors I can see all different kind of uses. For instance a virtual Wii IR bar for Wii emulation. Or help with recalibration of IR headset.
    Or even in games to search for hidden items or something using an IR camera.

    What do you think. And if you have any information why this is not a thing please enlighten me :)

    I think I would rather have 3d. At least that would be theoretically amusing.

    IR is just pointless for screens. The human eye can't see it at all. RGB color space doesn't cover it either.

    Did you even read the OP? Or just have a guess at what the contents might be based on the title?

    Well the idea would be to use the screen as a transmitter (not only for the human eye but also for other devices that we can interact with).

    I gave you one example. Emulate the wii IR bar. This would mean that you could connect your wii motes to the PC and use them without having to plug in an IR bar.

    A different idea would be to have more accurate motion controls.

    I gave you a few more examples. Like interaction with IR cameras.
    Lets say you make a game like Fatal Frame and include an IR camera for taking pictures of ghosts.
    That would be really cool. Because the ghost would only show up on the camera accessory.

    I can see many other uses not related to gaming as well. :)

    Plain and simple no one would actually use it. While not a bad idea in principle, you have to ask outside of gaming whats its use other than a novelty ?

    I doubt they’ll do this for a combination of engineering, cost and relatively niche market.

    For all the things you describe, external sensors are much more likely to be used since they can work with existing equipment and/or provide other benefits e.g. room scale.

    people cant see IR, no manufacturer is gonna spend money on an IR capable screen just to make it so you don't have to use a wii sensor bar when most people will never even touch a wii

    Well what's easier, making all TVs blast IR or just ship a console with an IR bar?

    If you think hard enough, you can see this is a stupid and ridiculous idea.

    Well I thought it was a cool concept. And I
    Yeah that was just one example. If I put it this way instead, If the TV's had that feature, Nintendo would not have needed to spend money and time on developing and manufacturing the IR bar. :)

    You forgot that TV manufacturers don't want to spend money implementing a technology solely for the benefit of an outdated gaming mechanic.

    @DaniPoo let me ask you this since you said you already had an answer, what is its use outside of gaming, that would make Joe Bloggs what to spend the extra $100 with this amazing technology ?

    Well the things I could come up with would be for instance, being able to transfer data to other devices in the room.
    Sure you could do it via Wifi, but it could be kind of cool if when you start a game the TV tells your lights to dim.

    Or you could have prettier AR (because you would not have to actually see the code)
    or use it for increased VR motion accurecy (VR is not only gaming you have pron as well :P)

    Well maybe it's not a super good idea from a financial point of wiev for the companies. But I still like it.

    I rather have that feature on a 4K TV then having an 8K TV. Because normal people would not even be able to see the difference from a normal viewing distance.
    I can understand 8K for PC monitors since you sit closer to the screen. But for TV's (unless they are like +70") nah!.

    yeah that is very niche and would not be picked up by anyone.

    Data transfer by IR is laughable at best. And why would i have IR talk to my smart lights when most smart tv's could do it by wifi or bluetooth ? The technology is already integrated to many tv's and supported by my smarthome.

    It's not a good idea at all I'm sorry :(

    I just can't see how it would improve my life or other peoples

    And its for that reason I'm out .

    That's why i mentioned the color space. Everything is built on the assumption of what the eye can and can't see. There will not be a new one just for gimmicks.

    @DaniPoo
    As others have said it would be much more expensive to make IR capable screens than having an external IR bar. This gimmick would make screens expensive and it would not work due to missing support. There is no encoding/color space which supports IR afaik. It's all just RGB or other ones made for visible light.

    Also keep in mind that almost all great ideas in history started off being attacked by sceptical people.
    Now we know that earth is in orbit around the sun and not the other way around, now Quantum physics is accepted (it took a while)

    Computers is an eveyday tool. Could you imagine..

    There was always sceptical people not embracing new ideas. ;)

    Bluetooth. It's called Bluetooth.

    There's no real practical application that having IR pixels would have that can't be done through far more convenient means.

    Most TV remotes still use IR, so it's obviously not only beneficial for games, but I suspect this hasn't been attempted because of cost. It would probably improve accuracy of anything that use IR tracking (a handful of smart TV remotes, some game peripherals) by a lot, I suspect, having many more points or a much larger point of capture, depending on implementation.
