Micro-LED Displays

In this video, let us talk about Micro-LED technology - the Prince That Was Promised.

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.

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.

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

[blackbriarmead]

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

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)

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.

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.

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.

[louroboros]

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

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

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

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.

[ancienttech]

Fascinating video! Very informative. I did want to point out that they actually used compact florescent bulbs for backlighting in some early LCD displays. I had no idea until I saw some retro computer channels having to replace them.

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.

[andytroo]

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.

[robertmartin]

LED backlights were only became a thing in the early 2000's. In the 1990's it was all cold cathode fluorescent tube backlights.

[michaelbeckerman]

Given the difficulty and the costs involved it's looking more and more like MicroLED displays may never come to market in the kinds of quantities that everyone was originally hoping for. That entire area of technology may well just be skipped and/or set aside while others (and older technologies that can be mass-produced affordably) are updated, advanced and approved upon. And, that's all perfectly fine as not all technology necessarily needs to find its way through to direct commercial viability. Besides, there is still a LOT more performance that can still be squeezed out of existing display tech like LCD and OLED. Every year companies find new way to improv on those platforms as well.

This is the best explanation of what MicroLED technology is all about and the problem with how hard it's to manufacture MicroLED's. Thank you for sharing this video and information with us because now I fully understand why it's taking so long for this awesome technology to be available for purchase. Hopefully one day we will have the opportunity to purchase a MicroLED at a price that most of us can truly afford. Please keep up the awesome work and I promise to keep coming back for more and sharing your video's with as many people as I possibly can because you definitely deserve all the exposure that you can receive...💯👍
