This video is a great primer on the state of the art of display technology right now and seriously changed how I view each tech. Seems like there is a lot of convergence between the main technologies and they all borrow from each other in different ways in their pursuit of the ideal display.

IIRC talks about PHOLED as one of the upcoming technologies to get to the pinnacle.

I'm still waiting for my affordable microled displays.

But the last few years they became noticable used.

This year in a outdoor it event I had to check the display wall behind the speaker to check it out.

It was full color, fast, bright (we are talking no cloud hot bright summer day and that display was in the sun and it was LEDs!

Crazy impressive

I'm still waiting for my light field displays.

I've got a Looking Glass Portrait and it is spooky how effective it is (although it depends a lot on the quality of your depth map.) The software is terrible though and getting stuff onto it is a chore.

Their upcoming model (currently on Kickstarter) is internet connected, so will presumably be easier to put content on it

Is it worth $250 though? A 2 hr battery seems short, though if the software can automatically convert all my old photos into 3d, I would buy. (NERFS and gaussian splatting)

I think my friends would love to see our old memories come alive again

I've converted a bunch of old photos to 3D for my Looking Glass portrait -- it's more like 2.5D because the depth map generators tend to slice photos into planes which pop out but if you're artistically inclined, you can tweak the depth maps using Photoshop etc. -- and it is quite startling to see old photos come to (semi-) life.

So much marketing speak and AI hype yet not even the slightest hint at how the thing actually works. I presume it's a high-density LCD with some kind of micro-lens array in front of it?

It looks like the last time their website had content was 2016 - https://web.archive.org/web/20160726091433/http://www.io2tec...

But it is (was?) essentially a projector that used lasers and a small amount of ultrasound-generated fog (which they really downplayed in favour of a lot of talk about focused air currents) to project a 2D image in space. They termed it a mid-air hologram.

Perhaps not the best tech for viewing anything much, but surely we all want to recreate Princess Leia's projection from Starwars?

Apple has been rumored to be working toward MicroLED displays in their products for a while, popular opinion is that the Apple Watch will be the first one to make the jump like they did with OLED.

Now that they have the Apple Watch Ultra at $800 and in comparatively low volume (I assume), I won't be surprised if it shows up in the next version of that, then makes its way to phones and elsewhere.

Makes sense, it has the smallest display so it is likely a good test bed for the manufacturing process.

Unless it's small enough that they just go with the other manufacturing tech where the display is on wafer and you don't have to deal with the pick and place mess. Which it almost certainly is.

Isn't the Vision Pro is using microLED?

Micro OLED for those
