cpus/gpus only need to grow the die on the wafer. they dont have to pick up the dies from the wafer and then move them over to another substrate like in microled displays. plus a cpu only needs 1 die to function. in a microled tv each led is a die. a single 4k tv will require 24 million dies and you cannot have a single defective die or the display will have a dead pixel. Even with a 99.99% yield rate, you will be left with 100s of defective dies for a single tv. @@ivanjermakov

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.

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.

[@rugvedmulay5090]

So does LCD need more battery to block the light?

[@EricChiEric]

i think it depends if it is a tn or ips display

[@MrDuncl]

That depends on how you align the polarizors. How many of you flipped the polarisor in your calculator to get a clear on black display ? Some LCD watches are made the same way to make them look a bit different.

[@maidpretty]

Only TN (twisted nematic) LCD that are used for entry level TV/displays are normally open ("on" with no electric field, "off" with), IPS-types and VA-types TFT LCDs that are used in most displays/TVs are normally closed ("off" with no voltage). That's why "dead" pixels tend to be bright on TNs and black on others.

Same, I only started learning about monitors after I got an OLED phone and it looked better than LCD and I was like hmm why is this a thing Crazy how the only actually good technology (microled) is so insanely expensive

[@e8root]

You would think you just need to use typical methods you use for putting components on PCBs... and yeah, it is how they make them but if you consider size of the display. number of LEDs (8.3 million for 4K display! Or 3 times that if you choose to use separate R, G and B LEDs for higher brightness) and that you are directly looking at such PCB where each part glows for better visibility it then makes sense that cost for making such display would be high. Not to mention all the LEDs itself are pretty expensive. What we really need is to have something where each LED can be grown directly on the panel substrate - in this case it will be blue LED and quantum dot filters will be used to make it RGB... and actually it is most probably how it is made with MicroLEDs because even if inorganic LEDs do burn-in slower they are still exhibiting reduction of brightness and different colors experience it differently. You would not want your fancy MicroLED that costs million dollars to get yellow or pink or blueish, etc. over time.

[@N0Xa880iUL]

You're exactly right! That's why I was always amazed by how cheap color displays had become.

[@e8root]

@@xenird MicroLED also has compromises and flaws. It is only perfect when you don't see it. Besides as far as colors are concerned QD-OLED has almost the same colors and is very much like mobile OLEDs but does not have issues with MURA, dirty screen effect and doesn't burn in as much and certainly color doesn't change over time. The only thing MicroLED has over QD-OLED is being able to be super bright.. ...and otherwise you did see MicroLEDs! All these super bright billboards that you always wondered why they are legal when they blind all the drivers are using the same tech - MicroLED just have more tightly packed pixels and typically you don't see any effort to correct gamut of ads on these billboards so colors there look ridiculous and MicroLED TV will have gamut corrected. Otherwise issues you can see on these billboards are the same as MicroLED has - just being indoors tech MicroLED has less issues like these... and if anything technician will come to your mansion and will repair them for you :) Otherwise where it comes to actually good display technologies for home you had Pioneer Kuro plasmas - the TV you if you have today you can expect that people who visit you and see this thing will comment on it and ask you... why the hell does this TV looks so damn good??!! And no, it isn't limited to LCD users. Less so QD-OLED users (because WOLED is simply worse) but even then these plasmas were much better tuned for humans where it comes to light spectrum.

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.

Let’s just hope that the end result also checks some of the other boxes that are often secondary in a tech race, like sustainability and low toxicity.

[@Max_Jacoby]

SSD is better technology than HDD but it can't kick out HDD for decades. So HDD companies had plenty of time to catch up. Whoever comes to new display technology first only gives their competitor a hint not a kick.

[@OrafuDa]

@@Max_Jacoby You may be right about that. Let’s hope that. On the other hand, there were companies set up to make e-paper (aka e-ink, which Kindle devices use) much better, with colors, even better contrast and lighting, and I believe higher frequency of change. But that development has stalled, because tablets and mobile phones have such a big chunk of the market. There is no good prospect for making money with better e-paper. For a technology to justify development costs (ie. improvement costs, not just survival), its market niche needs to be large enough and significantly different from competing technologies. SSDs are superior to HDDs in almost every way, except for the cost per storage unit. And HDDs beat SSDs by a high enough margin on cost/storage so that people still want them. And decades of prior development and enough accumulated knowledge about how to improve HDDs probably also contribute to them getting better. But, on the other hand, what people really want are way cheaper SSDs. And as soon as that happens, there will be no reasons for anyone to invest money into improving HDDs further. With display technologies, it is a similar race. They have become similar enough so that one of them may become superior in every important aspect to the others. Maybe a competing technology will still be far better for, say, small or tiny high-resolution displays as the “winning” technology. That would be a niche that *might* make enough money and hold enough prospects to justify further development. But if the “winning” technology has a convincing roadmap to cover that niche as well, then interest and investments in the niche technology will dry up. We will see how it goes.

I dont think laptops/monitors OLEDs are using pentile from what I know. That seems to be more prominently seen in AMOLED/smaller OLED types. The problem with laptop/monitor OLED is that they're using WRGB, which is where the text legibility issues are coming from that you're probably thinking of. Using aligned RGB will fix this, but it will require a specific OLED manufacturing process to produce these displays and there needs to be enough displays sold for this market to justify designing and building that manufacturing process(for economy of scale reasons). In the meantime, there's gonna be some coming improvements to WRGB OLED that will specifically help this issue, even if it doesn't fix it totally.

[@ShornDunlevy]

It's worth noting that the earliest LCD displays in which a pixel was made from 3 vertical strips of red, green & blue were leveraged by Microsoft to produce a system called 'Cleartype'. Put simply, as long as you only intend to produce greyscale (as it common for text) then it's possible to introduce what is known as sub-pixel rendering. Since the strips repeat RGBRGBRGB and so on, you can (for example) switch the GB of one pixel on & the R of the pixel to the right of it to on. So instantly you can shift a pixel by 1/3 or 2/3. Sadly LCD screens no longer work that way BUT on platforms like the Gameboy Color, a few developers used this trick to produce much clearer text (hence the name Cleartype).

[@ParallaxFPV]

I think we're still falling short of perfect display tech in several ways not mentioned. Firstly in the days of CRT tvs/monitors you could input any resolution you like and the electron gun would project it perfectly with no scaling, since we moved to LCD/Plasma/OLED displays we've had to upscale to the nearest resolution that divides perfectly into the native resolution or end up with an ugly aliased image. Secondly since both LCD/OLED displays employ a sample and hold rendering method our brain does not distinguish a clear gap between frames so motion clarity is still leaving much to be desired, Black Frame Insertion is definitely helping but at the cost of luminance. CRTs absolutely had their drawbacks and they were retired for good reason, but there are still things they do better than any modern display technology.

[@maynardburger]

I mean technically there's still a lot more that theoretically could go into a 'perfect' display. Fully transparent, infinite refresh rate, wirelessly powered, physically configurable aspect ratios, 3d/holographic capabilities, etc. That said, I wouldn't say there's a 'lot' to be left desired in terms of motion clarity of OLED. The fact that sample and hold isn't literally perfect is not necessarily a bad thing as it's not inherently a good thing to be able to more clearly discern gaps between frames.

Your second issue isn’t really a knock on display technology, it’s a result of content with low frame rates. You can make the argument that the perfect content would have such a high frame rate that it would have indistinguishable frames. This content’s motion would display perfectly on OLED TVs without judder. Real life isn’t in 24fps and I think many would argue that a perfect display’s goal should be that it’s indistinguishable from real life.

I'd argue one thing that none of these display technologies is trying to solve, unfortunately, is motion clarity. Picture quality is absolutely important. But motion clarity and input response from CRTs SHOULD be also part of this holy grail. Input response is pretty good on OLEDs that support 120hz. Don't know if it matches the analog latency, but it's definitely good. LCDs seem to often fall short (probably because of the sheer amount of processing required to achieve similar quality to OLED). But motion clarity WITHOUT input latency cost is still a massive issue on all display technologies. I'd assume OLEDs with lower power consumption, higher refresh rates, and some kind of ULMB or BFI support AT those higher refresh rates will resolve this. Or if Samsung's LCD replacement technology is able to achieve similar results to OLED with none of the downsides of LCD that could also work. But I think not. The nature of using pixels in the first place creates a sample and hold effect. And if we can't address that while still having sub 16ms latency then I'd argue both issues (motion clarity and input latency) aren't resolved.

[@G0A7]

From the test ive seen oled is closer to having less ghosting than It should, the pixel response is so fast that sometimes you lose the smooth movement and start noticing something like steps between frames Its noticiable watching low frame content like anime or slow panning shoots in movies, even more if its a environment shoot from high Some oleds have a option in the software to improve this, Idk in other brands but LG calls It soap opera effect, for me is just a blurry mess so i dont use it, but im also a user with a 120hz mobile, monitor and tv so maybe im more nitpicky to this motion blur

You can't solve input lag with pixel-based displays. Ever. The lag is always going to be 1 frame length at a minimum. CRTs were literally driven by the signal that was input.

[@shmehfleh3115]

I think that OLED's tendency to burn in is a little overstated. What you're generally seeing in those burn-in tests is a worst-case scenario: The TV is left on constantly, showing a relatively static image, like a news network's chiron. OLED sets go through image refresh cycles when they're powered off, to at least try to counteract the problem of image retention. If the set stays on all the time, that process never gets a chance to run. LCDs can have image retention problems, too. Granted it takes longer to show up on one, and it's usually reversible unlike actual OLED burn-in. But not always. I've seen plenty of LCDs with the ghosts of static images permanently stuck on them, including my own computer's monitor. In any case, even inorganic LEDs lose brightness over time, with the blue ones fading first. They tend to fail sooner and more frequently as the LED die is shrunk too, so I would expect micro LED sets to at least have some potential for burn-in and dead pixels just like the others.

[@mrlightwriter]

I think that's why mobile screens are slowing using OLED's. Because you can replace a mobile screen not a monitor screen by paying some money.

What a fantastic video! I thought I knew a lot more than I really did. I wasn't aware that W-OLED doesn't have true rgb LEDs. I also had no clue what quantum dot stands for. I kinda just blindly assumed it was a dumb marketing term.

[@PSYCHOV3N0M]

QLED is a dumb marketing term. Nanocell is a dumb marketing term. Liquid Retina Display is a dumb marketing term. Quantum Dots isn't.

[@Wobble2007]

Current QD tech is just a quantum dot treated film layer, true eQD, aka self-emissive QD, that is the real exciting prospect, it has the potential to completely surpass anything we have ever seen and will completely make all other displays obsolete, even the best late generation CRT monitors and Plasma Kuro and Neo displays, but like mLED, eQD is 15-20 years away, Tandem PHOLED is the best we can hope for through the next 10-15 years, they could combine MLA with QD treatment, imagine those MLA lenses treated with quantum-dots on a Tandem-PHOLED display, that would be incredible, especially if it had a true 8K dynamic resolution.

I wonder if the MiniLED technology could evolve to make the backlights at pixel level sizes, thus making the crab analogy in this video even more true when it comes to LCD displays. A MiniLED display such as this could in many ways rival the OLED technology itself, because of the high brightness and no burn-in of the LCD technology. If that happens, I would seriously consider the MiniLED technology moving forward. Well, as long as MicroLED displays or similar technologies at consumer prices are still not a thing by then.

[@alexthampan9007]

If it has become pixel size then there is no need for a LCD layer. At that point it would be a Micro LED display.

[@Almohebful]

MicroLEDs are better than LEDs when you can make backlights at the pixel level. Why would we bother to put color filters when we can make RGB subpixels individual LEDs at pixel size?

[@GAG091186]

MicroLED displays still have the red, green and blue subpixels that are needed for each pixel as far as I know. However, a QD-MicroLED display could be possible if the backlights were pixel sized if I'm not mistaken. Correct me if I'm wrong.

[@alexthampan9007]

@@GAG091186 QD Micro leds are just blue micro leds with QD color filters currently. Research is going on in developing QD LEDs or Electro luminescent QDs which are essentially true quantum dot LEDs but currently they have issues with stability and have short lifespan.

[@alexthampan9007]

@@Almohebful No there are uses for having a LED + colour filter approach because it can be scaled easily, is less complex and reduces cost. It is easier to fabricate a Micro LED of one color and apply QD colour filter than fabricating LED for each separate colour at pixel level. What having LEDs of pixel level eliminates is the LCD layer. Technically it will be a Micro LED display.

In almost 20 minutes about displays you managed not to mention PWM. Amazing

[@3D1ofakind]

I never knew there was such a thing as brightness efficiency in a tv. The idea of 5,000 tiny lenses per pixel to direct more light into your eyes is impressive engineering

[@CyberSystemOverload]

Brilliant video with effective animations showing how it all works. We all face this tech literally every day but take it all for granted. The absolute wonder of how these things work blows my mind. Maximum respect to the clever people out there who make this happen. Power of Science 💪 So glad I discovered your channel. Please have my sub! Oh and: "LCDs and OLEDS are both kinda false crabs" I can't 😅

[@elddery]

It`s truely a masterpiece, you perfectly mixed two different spheres of science to make a great analogy and described engineering theme with a biological evolutional parallel, I`m your fan from now on.

[@vivisector3489]

This whole carcinization analogy doesn't make any sense in this context; is it really that surprizing that people are trying to make a good display no matter their manufacturing methods? .. Carcinization is surprizing because it's not intuitive that crustaceans are somehow an optimal form, mainly because we're not that. But with displays we know exactly what we want to accomplish. Good video though, just drop the crab stuff.

[@forasago]

"it's not intuitive that crustaceans are somehow an optimal form, mainly because we're not that" yet.

[@maxheadrom3088]

2:00 it's not a current, it's applying an electric field. Though a current can be measured while the liquid crystal is polarizing, once the process is over there's no more power consumption - hence the ever lasting battery on old Casio watches. Liquid Crystals are molecules that can be polirized via an electric field - I heard a protein extracted from carrots was once used.

I got a WOLED LG monitor and I prefer the lower brightness because it never strains my eyes. I believe playing on the super bright lcd display of the Gameboy advance in the dark as a kid is what destroyed my vision.
