IT FIXES EVERYTHING

deprecated by woled

>>106005324 (OP)
Looks cheaper to make, also. Though I admit ignorance on the components needed.

microled will fix it

>>106005345
it's cheaper but only because they pump the glass substrate out using the same machines a windshields

don't blue LEDs degrade like 10x faster than red/green LEDs? wouldn't burn-in be a major issue because of that?

>>106005492
Not really a choice since they need to pick the shortest wavelength if they're going to convert it to longer wavelengths. Unless they come out with a super efficient UV LED or something.

>>106005324 (OP)
Crystal LED, that's the only way forward for flatpanels. Everything else is subpar and cope.

I have an old laptop with a white dot in the screen. Whcih of these will Inwant to purchase 5-10 years from now?

the display of tomorrow will just be a brainchip that tells your brain that writes video data directly to your optical cortex

I think I stick to my TFT, that works 15 years without break. Had a few stuck pixels but throwing random RBG noise at them fixed these. It's the indestructible Dell U2412M on DisplayPort™

this is my html file for it
it's random numbers to RGB
enjoy screen repairs, TFT never break, the rarely get stuck and it is reversible
cheers!

>>106006767
>width="1920px" height="1200px"
This should be adjusted for the monitor's native resolution?
>this is my html file for it
Copy that into Notepad, save as an *.html file, and run it in a browser at fullscreen? If so, how long?
>TFTs never break, they rarely get stuck and it is reversible
Do you know if that applies to TN, IPS, and VA panels with LED (non-OLED) backlights? For reference, I have a TN panel with a W-LED backlight.

>>106007202
>This should be adjusted for the monitor's native resolution?
yes I left it in a way that you can adjust it to your display, then you press fullscreen
>Copy that into Notepad, save as an *.html file, and run it in a browser at fullscreen? If so, how long?
that's the idea, a 15 minute run usually fixes all stuck pixels
>Do you know if that applies to TN, IPS, and VA panels with LED (non-OLED) backlights? For reference, I have a TN panel with a W-LED backlight.
in any case, it will not hurt them. TN should work as well. these are just like TFT but with a more narrow viewing angle
good luck! also I hope you don't have epilepsy.

>>106007202
>>106007213
nevermind, I've been calling my IPS constantly TFT for no reason, yes TN/IPS all good

>>106007213
>I left it in a way that you can adjust it to your display
Did you write the code? If so, did you learn how to do that from somewhere or was it common sense?
>I hope you don't have epilepsy
While I'm unaware, I'll probably leave the room and try not to look directly at it when I close the browser tab upon returning. Maybe even shield my eyes.

>>106007249
largely but I had to learn about how to draw a canvas from raw data. you see it is ARGB with no transparency and then you for-loop over each pixel in the square block

I'm not with 2d or canvas so that is stolen ofc
and you see math.random on JS is terrible

https://thenextweb.com/news/google-chromes-javascript-engine-finally-returns-actual-random-numbers
the squares you see are the repeating squares because it doesn't matter to waste clock sizes on drawing the entire screen space in a large canvas

so just generate a tiny one and make a tiling background.

they spent trillions trying to reinvent CRTs and failed

>>106006767
This is real neat. Thank you for sharing it. I gave it a try, forgot to adjust to my native resolution (1920x1080), and it looked the same later when I did adjust it.

>>106007464
No problem mate, works fine on mobile devices and laptops too. TN and IPS will outlive any OLED!
Thanks for the pic, haven't run it myself in a while. Seems to be working as it did when I coded it.

>>106005324 (OP)
still inferior to crt

>>106007523
There was literally nothing wrong with this. Even the form factor was a solvable issue.

>>106005324 (OP)
Pretty much. I bought a 1st gen QD-OLED monitor at the same time I built my current 7800X3D + 4090 system and I love it. I'll take the occasional interruption to run the pixel refresh cycle over having to choose between the various trade offs of LED panel technologies.

>I'll take the occasional interruption to run the pixel refresh cycle over having to choose between the various trade offs of LED panel technologies.
What shitty model did you buy that interrupts you? Mine does it when you turn it off automatically itself, no pop-ups or interruptions.

>>106008437
Fuck me, I meant LCD panel technologies.

>>106008485
None of them literally interrupt the user, you doofus. It just pops up a notification after 4 hours of cumulative use that it's due for a refresh. I usually just run it then because I don't play modern multiplayer trash, so it's rare that I can't just take a break right then.

>>106008538
>It just pops up a notification after 4 hours of cumulative use that it's due for a refresh.
See: >>106008485

Pop-up aka notification.

A pop up notification is not an interruption and I didn't make any claims about your monitor. What is your point?

>>106008699
Shit, I meant this for >>106008572

> you literally can't calibrate any OLED without a 7000$ calibrators for HDR and shit
why the fuck should I pay for something I cant use in it's full potential

>>106007523
I don't get this meme. It's not like we have 42 inch, 4K, 244Hz, HDR, VRR CRTs in stores.
What could have been, sure, but we sadly don't.

>>106008720
You can rent them. Also even within a few % of its calibration, it's still better than the alternatives.

>>106008747
any calibrated monitor is better than all best not calibrated monitors

>>106008752
ah yes this calibrated NTSC 70%, 300 nit VA panel is going to do so good at HDR compared to a from factory 99% Rec. 2020, 1000 nit OLED

>>106008720

Do you mean software calibration won't work on an OLED panel?

I hate this gay ass consumerist society.

>>106005492
>don't blue LEDs degrade like 10x faster than red/green LEDs?
I think that's only the case with OLED, not with (non-organic) micro LED's.
Or at least the non-organic blue LED's should last a lot longer than organic blue LED's, so even if it's still shorter than non-organic green LED's it's still an improvement.

Also one way to get around this is to use more/larger blue LED's compared to green/red so they can be driven at lower voltage which makes them last a lot longer (it's not linear).

>>106013591
>red or green backlight that then generates blue color with QDs.
Can't be done because a blue photon has more energy than a green photon which has more energy than a red photon.
And they can only take away energy or turn one blue photon into multiple greens/reds.
The other way around would mean combining multiple green photons into a single blue photon - and I don't thunk anyone has ever manged that.

Normal room lighting LED's are also blue LED's covered in phosphor to generate the rest of the spectrum.
They last for many years even when kept on 24/7.
In fact when they fail it's usually the power supply not the LED's themselves.

>>106005324 (OP)
It fixes everything! Except...
Fucked up pixel layout
Aggressive ABL
VRR flickering
Poor low luminance uniformity
Black crush
And it still burns in unless you perform humiliation rituals (then it will only burn in slightly slower)
But those perfect blacks you only really notice in 5% of situations are totally worth it, goy!

>>106013700
https://en.wikipedia.org/wiki/Second-harmonic_generation

>>106014051
>fucked up pixel layout
not an issue, subpixel anti-aliasing was always a hack for the incredibly low PPI LCDs at the time
>aggresive ABL
not an issue with standard brightness modes
>black crush
not an issue, calibrate your monitor

the rest I will give you are annoying, and the price is still outrageous, but in exchange you get
>ultrafast refresh rates
>ultrafast response times
>perfect blacks
>infinite contrast
>incredible color gamut and color accuracy
>no backlight glow or haloing
>perfect display from all viewing angles

>>106007625
Too small. I have a 4k curved 55" monitor. There's no good way to do that with a CRT unless you're okay with some 2000lb monstrosity that uses 500 watts.

>>106005324 (OP)
Enjoy your flickering piece of shit raping you eyes relentlessly. Every OLED flickers at 31 rgb and below at refresh rate intervals. Take your Magnesium

>>106008793
it's poorfag cope, every thread about monitors on this site is poorfag cope

>>106007523
they probably could've made CRTs much thinner by mounting the electron gun perpendicularly to the display and then using fiber optics to bend the light onto the screen
althouigh, the resolution would then be limited by the fiber density

I often leave my IPS on for hours and sometimes days because I just forget to close my browser, will an OLED not burn in if I forget to turn it off?

>>106015725
behold

>>106015841
not foolproof
Like that anon said sometimes even your browser can prevent it
My monitor wasn't turning off for a while, eventually went into cmd and used the powercfg thing, and found out it was the browser.
Narrowed it down to a gif in some random tab that was keeping monitor on the whole time

>>106015181
>Infinite contrast
I fucking hate this normalized buzzword
It literally cannot have infinite contrast, they are claiming that from a byproduct of the outdated method needs to measure contrast ratio

>>106015536
Or multiple tiny guns.

>>106015536
>they probably could've made CRTs much thinner by mounting the electron gun perpendicularly
some smaller portable crts does this
https://www.youtube.com/watch?v=l9CXZXSwG7I

>>106015536
why even an electron gun, surely something similar could be achieved with mirrors and a laser

>>106015841
I have these settings but if I leave YouTube playing it prevents my PC from going into sleep/powersaving

we should just go back to CRT. It looks better.

Trying to buy a high end 21" or 22" pc crt monitor rn (the sony fw900 is way too expensive because of the hype)

>>106017888
I think CRTs are stupid clunky and have burn in issues. I am intrigued though if they could make quantum dot CRTs

>>106018160
>burn in issues
even under the worst conditions, by the time a crt gets any noticeable burn-in you would've already went through 3 modern "gaming monitors"

>>106015536
impossible to focus. you can't have significant differences in distances between the guns and screen across the image

>>106018160
I know quite a few people buying 25 year old PC CRT monitors and most if not all are in excellent condition and have no noticeable burn-in. Only the ones that had truly excessive use (such as 24/7 on in an office for 2 decades) look fucked up, the others look fantastic really. Let's see OLED last that long without burn in.

The only CRTs I've ever seen with burn in are old arcade monitors that were displaying Pac-Man 24/7 for 60 years

>>106018269
This whole burn in thing is because Linus made a video trying a CRT monitor and it looked burned and very dim.

>>106007333
truth nuke

>>106018439
burned in a worn down are different things. i used one crt monitor for 10 years (family pc turned my pc) and i did notice near the end that it was dimmer than it used to be, but it was not burned in in the sense that there were persistent noticeable shapes in the picture. the electron gun fires electrons, but those electrons don't come from thin air, they're boiled off a plate inside the gun and are a finite resource

>>106018213
Thats what the fibers are for, make them equal length like the traces on a circuit board. EE 101

microLED + black layer is winning now

>>106019923
that's fair actually, though actually fixing crt output to an untold number of fibres in an array would be pretty complex
we already had a better solution for a thin crt, called SED, which died in 2006 due to patent bullshit. it was also fixed-pixel since idk how you'd do "thin" otherwise, but it was basically a 2d array of tiny crt's, to put it in simple terms

>>106015536
Anon...
The "electron" gun fires electrons. It does not fire visible light. Electrons don't go through fiber optics.

>>106017201
I think SED was basically like that.

>>106017276
It exists and is a commercial product, but not for typical consumer displays.

>>106019822
>they're boiled off a plate
lol. kids these days. There is a filament. like an incandescent light-bulb. It gets hot. Then apply a high voltage between that filament and a grid behind the display. Electrons 'boil' out of the filament. They don't run out - it is the current though the HV power supply - but the filament could burn out like a light-bulb (they only get red hot, so they last a long time).

I can't bring myself to care about smartphone displays. They're tiny anyway, phones are only good for texting and talking primarily, even if I play the odd video it's not like I'm actually going to give a fuck about the video quality on this fucking tiny 6" display or something. It's alright and doesn't matter as long as it gets bright enough to be readable outside and isn't total dogshit quality like a TN panel from decades ago.

>>106017332
yes? working as intended

>>106018222
> Let's see OLED last that long without burn in
If you run an OLED at the same brightness as a CRT it will last for a long time. OLEDs burn because people are running them at insane brightness level far beyond what a CRT would typically run at.
