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

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.

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.

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.

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.

Crustaceans and other animals did not evolve. Among the millions of fossils dug up from the earth, there is not a single intermediate fossil that proves evolution. Several hundreds of millions of years ago, crabs and other animals were in their current form. The theory of evolution is a dogma without any scientific proof. The reasons for defending the theory of evolution are ideological, not scientific. Scientists have discovered that all organs, which evolutionists call obsolete organs, perform important functions. Mutations believed to trigger evolution have been shown to be completely harmful. That is, mutations do not give advantages to living things. On the contrary, it harms. Evolutionists pointed to fossils of the coelacanth fish as evidence of the transition from water to land. However, a living specimen of this fish was found and it was found that the coelacanth fish is currently a fish that lives on the bottom of the ocean. Finally, I would like to mention that evolutionists can't explain how a living organism arose from inanimate matter. Living things did not appear through evolution, but through the Cambrian explosion. This proves the creation. Almighty Allah created all living things. Praise be to Allah Almighty, the Lord of the Worlds!

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.

The sad part is that CRTs still are better in many ways, I wonder how far that technology could have been pushed if endless resources were poured into them like LCDs and OLEDs have been. To be blunt, not a single new display method will come close to the response time or refresh rate of a good CRT. Not because I say so, but because the way the technologies work (and how a digital signal works) would require decades to make it work. The existence of any buffer system at all means that the response times in digital signals will always be bad, even the OLED that cuts response times to a fraction of its LCD competitor, is still far slower than a CRT.

@@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.

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).

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.

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.

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.

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.

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.

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?

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.

@@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.

@@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.

@TechAltar 11:19 Accodding to Chirag Shah from Samsung Display: MLA is a solution to a flaw inherent to WRGB OLED - it is a bottom emission panel, light gets scattered while passing through many layers, and MLA is there to keep it going straight through them, while QD-OLED is top emission, where Quantum Dots are under the antireflective layer, so there's little light lost and nothing to gain from MLA. Turns out it's not magic 60% boost, it's just 40% of power is wasted by old WRGBs. OLED aside, now I'm curious how QDEL is going to develop - can it get bright and big enough to rival MicroLED, and which technology will get affordable first? I just bought a TV, so for the next few years I can just observe the TV market 🍿

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.

2:10, yes, turn it all the way in one direction and we do have black (blocked light). But, turn it all the way in the other direction, and we will also have black. To let the most light through, we need the center of the liquid crystal layer to be at 45 degrees from both polarized layers. I don't know about current LCD screens, but in older screens (think black and white), the outer layers would have groves that the crystals would fall into and get forced into alinement, creating polarization. The next part is built on the fact that the crystals are magnetic. The crystals that are between the aligned crystals would get twisted by 45 degrees (which we want when letting light through) by the magnetic fields of the the crystals that are forced into alignment by the panel grooves. We can then cut down the amount of light that's let through by applying magnetic fields moving the middle crystals away from 45 degrees.
