DIY Perks is a YouTuber who's made some pretty impressive shit in the past, some good practical wise, others bat shit crazy, but this current invention feels like something that could be actually adapted for the TV market. He ends up recycling an old LCD TV and a projector to create a TV with a much better contrast than most LED LCD TVs.

This was a great video. I also liked that other one he did where he layered two LCD screens to make an OLED-like pixel perfect backlight.

Heh - that's actually pretty cool. I was thinking of same thing a while ago but never really figured way to align that black and white high-con image or actually syncing the image to both led panel and light source...
Still, I'm glad someone actually did it. Of course not so practical with a lot of OLED panels out there, but it's good to know that the theory worked!

Didn't Hisense do this in one of its TVs a few years ago?
And the Bravia 9 says that Micro LED is what Sony is going for.
Also he is clearly comparing it to a bad LED tv. A lot of newer models have very little bloom.

Yes they did. But it was incredibly expensive and came at the cost of way too high response time.

That was really cool. I wonder if the dual mirrors used at the end caused image degradation. I'd think even the cleanest best mirrors might.

Yup
Hisense U9DG Review (75U9DG )
The Hisense U9DG is Hisense's flagship 4k TV in 2021, and it's a very unique TV. It's the first widely available TV that uses a dual-layer LCD panel, with a 1080...

I doubt it. The only thing the mirror is affecting is the backlight, and that signal is already being blurred on purpose to refine the edges of the backlight.

That's what I get for skipping around. I thought the image and the backlight were both coming from the projector. Should've figured this guy would've called it out if it was an issue.
