What do u think of inktjet printer oled displays?

man I've been seeing this camera on Fortnine pretty frequently. its a sweet gear no doubt on that.

thank you for this video. if you search up how these panels work its hard to actually find good info. all google saysa is "lcds use a backlight" blablabla. i dont know what that means. but here you show exactly how these monitors work

Weird how you didn’t talk about pwm and how certain Chinese companies like oppo are using dc dimming to stop the effect.

Comparing MicroLED with OLED it's like comparing a lightyear starship with a tractor 😂

Not even comparable to tolerances in semiconductor manufacturing (10nm vs 100um, 10000x difference).

@@ivanjermakov Insane, they upscaled precision from 1um to 1000nm to 1000000pm. A whopping 1.0x10^0 increase in magnitude.

@@Gabtube252 haha, I had to read your comment twice

True. And yet people think this products are expensive. But when we look at the making of this, we realise that they are priced less wrt cost that goes in r&d.

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

Get outta here physics nerd! Very good, man. Thanks for sharing your knowledge :)

1990 was over three decades ago. That's not relatively new in terms of technology....

​@@jatoxo it is in terms of developing cheap mass production techniques. Solar panels are another examples. The main technologies were discovered/invented long time ago, but it took decades for the prices to become affordable

The Nobel prize for the invention of blue LEDs was well deserved

I thought blu-ray used a blue laser?

So does LCD need more battery to block the light?

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

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.

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.

@@EricChiEric What is that tn lcd display?

I had a similar feeling when I saw a TFT display on a laptop for the first time in the 1990s. Before then the infamous Dual Scan LCDs needed "mouse trails" to keep track of where the pointer was when you moved the mouse.

Sony was late to market even though they unveiled the first OLED consumer prototype

Definetly you never watched a CRT in the dark, it's the same as a OLED but with perfect motion, no aliasing and doesn't have a native resolution.

@@saricubra2867 not really. Crt has no deep blacks

@@miaya3898 it does have deep blacks like an OLED, the electron gun doesn't hit the phosphors for black areas therefore no light.

OR maybe most AVERAGE consumers don't care to learn because they're either too lazy or too ignorant. Don't blame the manufacturers. 🤣🤣🤣

It's not that they are bad, they just don't care to explain anything. They care only about marketable bullshit.

Not at all true lol. You and me are interested in this and like these type of stuff. But an average person couldn't care less other than the price and features that it offers.

​@@PSYCHOV3N0MWell, no manufacturer has ever explained their technology to this degree and this way so we can't know until they start getting better at explaining their tech

@@PSYCHOV3N0M No.. its the manufacturers.. .can't agree on standards. etc.. can't market.

Do micro LED displays use glass screens or plastic? One of the reasons I've always loved plasma displays is the glass screens. The optical properties of glass are unmatched.

I second that. That's really well done. Subscribed as well.

Same. Good job!

The best display tech already exists, it's called Cathode Ray Tube. No aliasing, no native resolution, perfect motion, infinite contrast (they are analog displays, not digital), variable refresh rates. The only weakness, they are heavy and bulky.

​@@saricubra2867imagine how fucking fast the beam has to travel to give us a 16:9 v200hz display lol. Also curved and ultra wide displays are near impossible to create. It's pretty good, but with all the limitations I wouldn't call it perfect.

i have a 2010ish LG monitor TV that takes a bit to fully warm up next to my more modern 2017ish Asus thats turns on instantly, is that the reason why?

Lower end monochrome LCDs used LEDs as well on smaller sizes.

@@q1337 Yep! I had a few LCD displays from that era that used fluorescent backlights. If I remember correctly, laptops made the jump to LED backlights first, with the rest of the industry waiting until the price of LEDs dropped to be competitive with fluorescents.

@@fungo6631 And higher end monochrome LCDs used electroluminescent sheets, which are now on their way to become "the perfect display" with electroluminescent QDs. That's some amazing convergent evolution.

Yep, I have a late 1980s Casio LCD TV, it's about 2" diagonally and 2" deep to accomodate a CCFL tube and light spreader. It's dim and incredibly uneven. Flat CRTs were much better but no one bothered making them color, that'd need Indextron type tech which was too expensive for such a niche market.

That's a common problem on OLED. iPhones have it, Samsungs have it. My first smartphone was a galaxy S1 (Back in 2009/2010) and it had the same problem, I now have a nothing Phone 2 and the problem is still there. It's less prominent when the screen is brighter,

I have a Xiaomi with AMOLED screen and I have never noticed that issue.

It's all about refresh rate or heartz

@@czech8797 I don't think so. I've tested with both 60Hz and 120Hz and they behave exactly the same. I don't think the refresh rate changes the speed it takes for the LEDs to turn off and on, only to change the colors of the LEDs that are already on.

@@sekkuar btw we can see that it by manually moving a app or black element, otherwise when you see videos you cant see because it's running in high refresh rate

Most of the power consumed in a phone comes from the SOC and inefficient software sadly

​@@SirDellaI love my android but it really was never meant to be used like this, as seen by how inefficient it's CPU usage and task scheduling is overall. Especially older Android suffered greatly from that, we kinda brute forced that by creating better, more efficient hardware.

Sony thought the future was Field Emission Displays. p.s. Check out the Mitsubishi 37" 4-3 CRTs. I knew someone who had one. It took four men to get it upstairs !

@@MrDuncl Remember the old rear projection boxes...speaking of Mitsu. I loved busting them open and getting the big lenses...looking at one now.

Japanese was always better than just about everything...remember Nakamichi?

The popularity of Korean dramas and K-pop is undeniable, and both are known for their high production values. This includes stunning visuals, often featuring vibrant colors, intricate details, and fast-paced action sequences, so of course, companies like Samsung and LG face pressure to constantly innovate and offer the latest advancements to stay ahead of the curve. The demand for superior screens also extends beyond media consumption. The rise of gaming, virtual reality, and other forms of interactive entertainment also incentivize the development of better display technologies.

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.

@@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.

Not really, the video explained that even tho new technology ("LED") has been out, people are still buying LCD displays and by a huge margin.

RIP Plasma

That's why Samsung is selling displays to other smartphone/tv brands

Exactly! I’m very excited for those monitors coming out in probably 10 years at least haha

The price of uLED will never come close to that of LCD displays. They will remain the highest end displays indefinitely.

You've got $20,000 to spend on a TV, I hope. They can only ever bring the price down to something that still approaches 'insane' by even most enthusiast standards. It is inherently expensive technology, far moreso than regular OLED. Unfortunately we've gotten spoiled with the idea that technology will always just keep getting cheaper, when there's lots of stuff that cant(at least practically) and have gone out of business/production as a result. Kind of a survival bias in effect. I think MicroLED may well face that same fate at some point, because its advantages will shrink, and the price gap for the remaining advantages will remain absolutely enormous.

Glad to hear! :)

Carcinosisation?

@@bobolobocus333 Yes i never knew about that ..

i have plasmas, and they have way better color than some modern led, and if you get a 1280x720 res one, they are superb. Cant believe he didnt even mention it, not a good analisis at all

Plasma used far more power than even CRTs. A friend bought one and it had three fans in the top to stop the insides from melting. On the plus side they did have much better contrast than any LCD at the time.

@@MrDuncl that is absurd, parts melting? A friend told you? i have 3 pionners, 3 sony, one panasonic all plasmas. I sold all my lcd, and led tvs, they cant compete in colors, resolution, yes, but not everything is resolution. The sonys are from 2002, not quite good, they have issues, pionner plasmas, are amazing, way better that the 50 inch smasung led my mother in law bought last year. You should get one, image color is amazing.

@@obturafotografia247 Maybe my choice of language was bad. However, I wasn't exaggerating about the three fans in the top of the Panasonic Plasma TV. I just looked at some power consumption figures from back when Plasmas were being sold and am seeing 400W compared to 120W for the same size LCD.

​@@MrDunclyeah, plasmas run hot, especially if they get bright. It's called plasma for a reason. I still use a 60" pioneer Kuro from 2008, and at least in a dark room, it's pretty much as good as a 1920x1080 modern monitor, and a fair bit cheaper than one.

i knew it will comeback sooner or later

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.

@@maynardburger Think of what they will have 100 years from now? Probably develop a pill you swallow, to develop an organic computer chip into your brain as you develop before you are born. Instant virtual reality at birth.

the down side of adding the black frames though is also more flicker also direct fade from frame to frame is bascilly 'free' temepral antialsiing

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. That said, I still have a hard time abandoning 24fps for films.

What OLED monitors use pentile?

Not sure if it is the exact same arrangement but same issues in first generation QD-oled panels by Samsung (see G8 oled). Their second generation had a different "better" layout, see G9 oled@@pickleadaykeepsthedoctoraw5542

It's a problem with Windows. F*ck Microsoft

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.

This. Hell, even with Steam Deck barely anyone talks about the fact that both screen options suck hard because of that.

he does briefly mention it in the introduction of OLEDs

Response time of OLED is so fast its actually bad for low refresh rates like 60hz. It feels a lot less smooth to me on my Oled than on my LCD monitors. Always get the 120hz if you can.

@@hmilles Now that you mention it, yeah motion clarity in general wasn't really mentioned. So refresh rates, response times and input latency

​@@cc0767my solution for this in games at 30 or 60 is to turn on motion blur in games. I know it get a bad rep, but it actually helps a lot.

as far as I know there isn't a display technology that can match OLED when it comes to response times

my first taste of OLED was in 2017 after buying a used Galaxy S4. then an S5, S6 Edge, etc., Now I'm typing this on a used 2018 Xperia XZ3. My first OLED outside of Samsung

I already have something better than an OLED, it's a high end CRT monitor.

@@saricubra2867 I still have a aoc crt monitor from around 2007. Is that considered high end?

@@miaya3898 It depends on the specs. Mine can almost do 1440p and it has better clarity than a 1080p display (smaller phosphors than pixels on a 1080p display), no aliasing.

If you are buying it now, it's already obsolete. always the newer improved versions are ready to go, after interest fades, and sales slow, and more importantly patents expire. Patents make mfgs. and creators of the technology, more money than they make actually making a product. Since it gets licensed to all others. ie the CD and CD players and even logos, was Philips big income maker, from all other makers.

@@cengeb i used to croled on my groled if you know what i mean

@@cengeb Patents really need to go in many areas and forms, it makes breakthroughs and new research slow and behind because there is no reasons to or it is impossible because of a patent blocking your way.

@@Wipeout186 Patents are the only reason why companies invet stuff, profit. they license the use and make money without having to even make the stuff. that's genius. Example the CD Philips invented it brought Sony into the mix (after Panasonic didn't want in, sony was 2nd choice, fact) Every maker of the discs, the players, even the jewel box it was packaged in was a Philips patent. Every mfg. using the logo even paid Philips a patent fee,copyright fee, royalty. . For the 17 years, then when it was expiring, that's why the SACD was introduced, new patents, but it didn't actually take off, like the original CD did, or DVD, which they also did, anything laser optical, Drug companies, same thing, patents bring in the money, more than making the actual stuff just by yourself. Once patent is off a drug compound, genericsf lood the market, company loses money, people benefit sometimes lower costs, but billions in research, won't be done if can't profit, Capitalism. So when display patents run out, they have to have something new to introduce, otherwise they won't survive. Patents does make new stuff being improved. If you invent something and can't profit from it, why would a company bother?

You can't, use of heavy metals that're required for CRT's is banned pretty much everywhere.

Turns out that led lined glass tubes are really bad for the environment... Who knew? But you can still get used crt TVs and monitors, so if you want one, get it while you can! Just understand how expensive it is to get rid of the things when the time comes. They aren't cheap to get rid of.

We still have our Panasonic CRT out on the 4 season porch, picking up over-the-air, serving a DVD player, and an old slow Roku. It's 21 years old now and still works fine at its native low rez. I hate to get rid of it just because it's old tech.

There are plenty of videos around on how CRT's work, the Slo Mo Guys have a couple of videos of CRT's in slow motion showing how they draw pictures on the screen. CRT's were the OG in dynamic contrast before OLED.

We have miniLED monitors currently with more than a thousand zones, so hopefully we'll see miniLED TVs within the next year or two with at least 1000 zones.

@@Slavolko when you use it for a long time, does it encounter bugs such as burn-in, ghosting, and screen tearing?

@@yasirarafat9279 Those aren't "bugs". Screen tearing doesn't really depend on the display itself. Ghosting is panel-dependent, but it shouldn't be an issue with high-quality miniLED panels. As for burn-in, they shouldn't burn in as easily as OLED displays.

LOL my TV is a 2008.

Massive Panasonic plasma fan. Got a 2009 model and the picture quality is still fantastic

me too! all hail the Plasma supremacy

Salve, plasma defenders!! It is at this moment that LCD and Oled evangelists are horrified by the supposedly dead and buried fans of (always superior) plasma TVs! Yes, we are alive, just like our beloved TV sets.

It's honestly too bad the technology couldn't stay competitive. Still remember connecting the ps3 to the plasma and loading killzone 2 for the first time and just being blown away by how good it all looked

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.

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.

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

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.

The OLED's burn in issue is definitely not overstated. I have an iPhone 14 Pro and I have burn-in. However, it wasn't caused by the always-on display, but rather the icons of Waze (I use GPS for about 1 hour each day).

I was worried about burn in, because my dad's Samsung Note phones all started having severe burn in after just 1.5 years. The back-arrow from telegram and the Keyboard were visible everywhere. But then I got my Xiaomi note 10, and 5 years later, I can kinda start to see some random burn in... But it's not permanent. I've noticed right after purchase that every now and then the display would shift it's pixels by one pixel, in a circle, making static images not static anymore and blurring potential burn in lines.

Nah, in 2 years my s20 fe burned in. It uses oiled. My cheap a21s I bought years ago still looks fine.

​​@@mrlightwriter WOLED and QD - OLED are less prone to burn in than standard RGB OLED used in phones.

@@Ishpreetb264 Wasn't aware of that. Good to know!

They're the exact same technology, mini led is just a brand for the fald using tightly packed brighter and smaller led for the backlight and separate zones for the individual leds.

What is the direct electron gun tech called? I can't find any info on it.

I thought this was already looked at many years back but it never went anywhere called surface conduction electron emitter display or sed tvs. Didn't they scrap this tech ?

The answer is very simple. Ask your friend if he/she intends to watch live TV channels with static logos and/or in a constant brightly lit room. The answer they give you will make it easy to choose between LCD or OLED.
