What happened to this technology? It was a promising alternative to oled. Can't seem to find any proper examples on dual layer monitors besides this guy's video
>>108483960You can get professional DL LCDs. MiniLED became more popular though. Also still suffers from VA / IPS faults, OLEDs benefit isn't just blacks.
>>108483960https://grok.com/share/bGVnYWN5LWNvcHk_af33d529-ecce-48c4-9c82-260f5bc6f92eSeems like it’s because manufacturers think consumers want thinner displays and lower power consumption. dual layer are the opposite. Thicker size, more power consumption, and more heat.
>>108483960The real question is why manufacturers bother with mini/micro LED backlights instead of making a dual layer monitor where one layer is LCD and the other is monochrome OLED
>>108484469They use a lot more power and require cooling. The designs are always thicker and heavier, requireing more parts, make less profit. That's why it's only professional expensive ones that ever used this design.
>>108484475I'm not OP, what he and the video are referring to is using two LCDs with a huge backlight, this is really thick as you need bright-ass LEDs to go through two panels+cooling for them. What I propose is a traditional LCD, but instead of a normal backlight, or smaller array of LEDs, a monochrome OLED is used instead.This should in theory be barely any thicker than a traditional LCD, be passively cooled (Regular OLEDs can handle that), and unlit LCDs use almost no power, consumption would be about the same as a normal OLED
>>108484502He does something similar in theory in one of his other videos.https://www.youtube.com/watch?v=qXrn4MqY1Wo
>>108484502>let's make it needlessly complex and still worse than OLED
>>108484502So... literally MiniLED? >>108484520or even MiniLED.
>>108484518I've seen that one, in theory what I propose should behave similarly while being way more compact (There's also the fact the projector's 720p and the TV is 1080p, so you're not getting a per pixel backlight, so this design is more of a pseudo-MicroLED)>>108484520OLEDs are bound by how bright you can make the LED responsible for the green sub-pixel, this is the reason LCD is still a thing in high end systems, as you're only bound by what's the brightest blue LED available (which you can turn white with a phosphor). It's complex, but not needlessly, you're getting the best of both worlds with both perfect blacks and HDR, while not having bloom around areas with a bright spot smaller than an individual LED in a MiniLED setup>>108484525In MiniLED you don't have an LED per pixel>It doesn't ma-There's a reason people constantly shill how MicroLED is gonna change everything
>>108483960efficiency is abysmal and active cooling is mandatorythis is just not viable in any way in consumer space
>>108484561gamers are already okay with their components being absolutely huge, hot and power hungry, don't think they're going to complain if the monitor is as well
>>108484614they already whine about actively cooled OLED monitors only to get cucked by aggressive ABLmodern lcd panels have single digit photon efficiencydual panels are well below 5 percent and it means the LC light valve needs 20~15k nits to get 600 nits out and this will consume around 100 watts not considering lcd driver or panel's consumptionyou definitely would not want this unless you absolutely have a reason toif you only game or do media consumption OLED is just better
>>108483973OLEDs are crap.
>>108484700OLEDs are the best we have right now when it comes to a all around display. It's just that they burn in, like your pic.
>>108484770See, that's my problem with current technology. SSDs die by design. And so do OLEDs... Can't we just have something persistent for once ?!Fuck !!!!!
>>108484832LCDs and HDDs die too though.
>>108484835Yeah but a lot more slowlyMy oldest HGST SAS HDD is 12 fucking years old with ZERO bad sectors so far.My 9 yo lcd monitors have no bad pixels at all, still working.
>>108483960you want innovation? you need to look at apple for this.https://support.apple.com/en-us/119963
LCD die yeah. but it is usually due to dried out electrolytic capacitors. i just replace em and im good to go. been running these 3 screens for the last 20 years. repaired each twice. this new shit is pure crap.
>>108484926CCFL LCDs used to die quite oftenLED ones rarely but when they do it's a PITA when just one LED goes
>>108484930>LED dieNever happened to me , and I hope it neber willLast thing I want is soldering these fuckers.
>>108484932You might as well trash it at that point, you're not going to replace the LED with one that has the same wear and you'll have uneven backlighting.
>burn inWhy not go back to using screensavers?
>>108484525Most miniLEDs have, what, 1000-2000 dimming zones? While a normal OLED has 2,000,000-8,000,000 dimming zones depending on resolution. That doesn't sound like the same thing at all.
Dual layer OLED is apparently becoming a thing to reduce burn-in, which I think is neat
>>108484962imagine ai generated screensaver>>108485000trips of trvke, 1~2k dimming zone is still a dealbreaker for melooks dogshit for nonmedia usage>>108485003it already is a thingLG display seems to be pushing it hard
Do you consider using high-quality SLCD as a effective way to cut costs while still retaining image fidelity?Also;):*
>>108484846not really
>>1084853533000 hours is nothing. Even CRT's lasted 50 000 hours.
>>108485390>CRTard
>>108483960Manufactures have decided it costs $30,000 for some reason.
>>108484948I would darken it with pigments or some shit
>>108483960Why would i do that when i can just make planned obsolescence the monitor tech and you retards keep buying it.
>>108485353>le it's just le minor damage after 3000h guise!!>actually watch the video>the guy says he plays Overwatch 30 minutes a day and the healthbar is permaraped into the screen>permanent screen damage from 30 minutes of 1 game a dayLiteral shill article
>>108486028This, there's a reason why things like microLED are always just around the corner, never actually releasing. They don't want goycattle to have tech that's the best of all worlds without built-in planned obsolescence. They want a consistent stream of repeat customers. There's really nowhere else to go with TV tech. Anything greater than 4K is a meme. People don't care about gimmicks like 3D, they already tried that shit. The manufacturers fear running into another situation like in the 90s when everyone got their CRT TVs and the market was saturated and nobody had any reason to buy another one. They want to be able to sell you an OLED consistently on a 3 year timeframe.
>>108486220Isn't damage caused mostly by heat? Are you sure the display wasn't kept in direct sunlight or something stupid like that?
>>108483960it's a retarded concept, MiniLED is superior in every way
I prefer the nornal LCD, you can see everything clearer.
>>108484469OLED is a fucking shit technology let it fucking die already
>>108484700that pic is older than some of the posters here
>>108484832>>108484846HDDs fail at a higher rate though, matter of fact I've never had an SSD die on me yet.My oldest SSD is an OCZ from 2012 or 2013, still works just fine with plenty of life in it.LCDs with CCFL backlight degrade and lose brightness over time, while cheap LED ones overdrive the diodes and also die. Image retention can also happen on LCDs, I've had it happen, I've had burn-in on CRTs too.
>>108490679spotted the poorfag
>we need a brighter backlightsounds like an easier engineering problem to solve than>we need billions of pixel sized leds
>>108490851except first one is a dead end tech while second one isn't
>>108490853Yeah, microLED can't come soon enough.
>>108490853>more efficient leds is a dead end technology???
>>108490856That or at least tandem RGB OLED that has is even less prone to burn in.
>>108490859You're still stuck with shitty LCD tech.>>108490856microLED is far away still.
just use better polarizers holy fuckthe 1000:1 absolute garbage economy polarizers are bottom of the barrelyou can easily make nanoparticle film polarizers that reach 10^8:1 now, or at least stay above 10^5:1 on the visible spectrum
>>108490957damn anon maybe you should apply to lg and earn 7 figures a year with your expert knowledge
>>108490841>spotted the no standards retard
>>108490841I wouldn't purchase the most expensive OLED on the planet even if I won the lottery tomorrow
Is OLED actually planned obsolescence?Just bought mine yesterdayUsing it at 66 brightnessI could not imagine using an LCD with the glow
>>108483960No it wasn't. It's a manufacturing nightmare, and consumes twice as much power. Miniled is the closest consumer product.
>>108491260Even if it was, it's too good not to use. I rather buy a new one every 3 years considering how cheap they are these days than put up with shitty LCDs.
>>108491299LCD is actually unusable after you have experienced any decent tech, OLED or Plasma or even CRTI put screen move to strong on mine since it has extra pixels just for that anyways, disabled the dimming stuff because its annoyingThe monitor has a prox sensor, when I move away from my PC it automatically enters stand by and when I sit infront of it it turns on again, really nice
>>108491306>1440plmao
>>108492149dude has like a 4070 non Ti
>>108483960It's very power inefficient.
