Micro-LED Displays

One of the biggest areas where the quality of picture on CRTs was seen as poor by the majority of people wasn't the fault of the CRT, but rather the noisy analog signal of broadcast, things like RF or composite video connectors, and things like recordings done on VHS tapes. All of these things combined created fuzzier, noisier images that the CRT would dutifully render for you. Granted a CRT is really inefficient and heavy, but input a signal with something like SCART or S-Video with a digital input source, and you'll get a clean image, even high definition models existed. Sony's Trinitron models always looked really good back in the day compared to other ones I used.

Ironic that the world has gone from Red LED's being the cheapest/easiest to produce and Blue the hardest/most expensive to completely the other way around.

Ok, so I can count on having a micro-LED monitor about the same time my local nuclear fusion generator comes on line?

I nearly threw my phone when you said that 90s era LCD panels (or any lcd panels for that matter) have better contrast ratios than CRTs

you don't know how much i'm waiting for Micro-LED tech

Those big stadium displays consume huge amounts of power. The largest reach close to 1MW at full brightness and many have their own air conditioning.

The invention of the Blue LED was so important that the inventor and the group that worked on it, both japanese researchers, received the Nobel Prize in Physics in 2014. Physics is considered one of the most, if not the most, hard subject to win the Nobel prize.

I saw this video and I was so excited. Micro-led is one of those technologies that is so perfect but has challenges including cost, manufacturing, etc, if I ever have the opportunity to buy a microled monitor or tv i'll definitely remember how far away it was in 2020

An expert interviewed on FOMO's channel asked to guess when prices will be attainable for consumers for micro LED TVs and he said around the early 2030s.

There was also a tech called SED (if I recall correctly) which was basically like having every pixel be a separate CRT (one electron emitter per pixel). Basically a truly flat CRT, which would have had excellent contrast (although probably the same phosphor burn in issues)

As a PC enthusiast I feel like Micro-LED is one of those technologies that has been 5 years in the future for the past 10 years

my guess is the QD-Leds will be the way to go - only blue backing mini LED's with efficient photon down-shifting via quantum dot to the colour wanted.

not another word against CRTs. Its superior to LCDs in many respects.

every single vid you make is an absolute banger. Id love for you to produce one on the back story and explanation of the tech in quantom dot. thanks for all the work you put into these

Good to see Plessey making an appearance. One of the rare UK fab companies, I remember visiting their Plymouth fab as a schoolkid in the early 80s, goggling at 3" wafers. The company's history goes back to 1917, or at least the name does; the logo comes from the days when it did lots of military radar. Not as well known as it shuold be.

If you think CRTs had poor image quality, then you probably only saw some heavily used consumer-grade CRT TVs with a low line count. Sony Trinitron and NEC/Mitsubishi Diamondtron and possibly other aperture grille CRT monitors had and still do have good image quality, though they might not be optimal for small text unless perfectly calibrated and in good shape. Aside from the bulky size, I'd say the main drawback of CRTs is the less-than-perfect geometry.

It sounds to me like the tech won't be practical until someone comes up with a way to just construct the pixels on the substrate.

Hey, don't forget the CFL LCDs! Those were where backlights really were most of the time until LEDs took over. I even had a MacBook with CFL backlighting.

I almost forgot all these problems with microled, great summary. The transistor once used to be impossible to make a reality. I guess these things just need the right minds and people together, that's what makes it such a slow progress.
