This makes you wonder how insane the machining and tooling of the industry must be to place millions of pixel so accurately

Blue LEDs are used for all Quantum dot displays, because blue has the highest frequency & energy among ( red or green or blue ), so its color can be stepped-down to red or green colors with quantum dots and little or no brightness loss. Also the creation of practical bright blue LEDs is relatively new (~1990), and not only enabled the reading head for 25GB blu-ray players (previously we only have 4GB DVD pllayers), but also these quantum-dot displays.

I love it when you analyse the trending innovations on actual tech. Not the gossip tech. I've been following you since 2018 and you never let me down with satisfying tech content. Thanks Marton!

Having spent a career in electronic image processing and display (see PictureTel, Polycom, HP), I find this to be a superb description of the current frontrunner technologies. It taught me several things in the most modern tech I did not know, and does it simply and clearly. Thank you for a very nice job!

I always wanted to know how LCD, OLED and LED displays worked and particularly how they evolved. A brilliant and very instructive video . Now my admiration for the innovators of these technologies has risen to greater heights. Thank you TechAltar for a really creative production.

Minor Correction: natural state of an lcd pixel is clear, not dark. With no electric field, the crystals naturally twist the light, allowing light to pass through. With a field on, the crystals line up end to end and stop twisting the light, allowing the polarizer to block the light.

I remember in 2012 in a big electronics store in Germany I saw a (in retrospective) tiny 12" oled screen on display for the first time. It was a screen by LG. The colors and black levels were out of this world at the time. It really got my 12 year old self excited for the future of tech. I was in that electronics store looking at this screen almost every two days 😅

I gotta say you cracked the algorithm code for nerdy techie videos while doing 0% clickbait + 100% good story telling

MicroLED is what I've always assumed normal pixels were like. I had no idea it was actually so complicated

[sekkuar]

I had two Samsung AMOLED phones in the past years, and one thing I've noticed is that there's actually a delay in turning the individual pixels ON or OFF.

For example if you have a picture with black parts of the screen and you scroll this image around (like scrolling pictures on Facebook for example) you can actually notice how the parts of the screen that were black takes an extra moment to lit up, and the parts that were lit but now have black takes a moment before they are completely black.

Not sure if this is a software issue or a hardware issue, but either way it's quite noticeable.

One of the best and most concise and accurate presentations of older display tech all the way up to the bleeding edge latest stuff. VERY well done my friend! Subbed!

Actually the backlight in early LCD TVs and monitors before the early 2010s all used small fluorescent tube bulbs that ran the whole width of the display with there being many of them across the whole display hight. Early backlit LCD monitors from the late 1980s only used a single tube to light the backlight spreader layer.

If the manufacturers were this good at explaining their tech more would be interested =)

[oBseSsIoNPC]

Just wow....this video is a gem, explaining the difference very well, regardless of some minor technical mistakes. The technology blows my mind and watching this on my Samsung S23 ultra, I can attest that the display is mind-blowing bright. I have no problems watching in bright sunlight and the brightness adjusts very smoothly to the environment.
It looks like they are moving quite fast through new technologies, I am very impressed.

[TheIntelligentVehicle]

This is definitely a classic TechAltar video. Such an accessible but (for the layperson) comprehensive overview. Many thanks, as always.

[aditya_on_youtube]

This was so beautifully explained! I recently bought an LG OLED TV and before buying I read up a lot about QLED, MiniLED, WOLED, QD-OLED and all. But this video gave me a better understanding than what I had got after watching hours of videos on other tech channels. Well done and thank you!

[davidbutler]

Amazing leaps and bounds in the display market since I was a kid.
Back then...The biggest CRT was like 32 inches and weighed hundreds of pounds, cost thousands of dollars and might last a lifetime...especially if it was a Sony.
The Samsung on my desk now is just as large, but weighs less than 20 lbs and was less than $300.
I was surprised to find out that both Samsung and LG are Korean companies...not that there's anything wrong with that.

[smartunknown]

This is an ABSOLUTELY AMAZING VIDEO. I dont know why but i think for simplicity many youtubers dont go into detail in these topics. And i love learning about how each of these displays work

[donaldobrien]

I heard "crap" instead of "crab"

[pedrosoares]

Finally I understand why white backgrounds on oled look green to me: the red, blue and green diodes are all maxed but we are more sensible to green light
