Not the most tech savvy person so please bear with me.
What exactly is it? What’s the difference between it and something like FALD? Are they the same and it’s just different marketing or are they actually different? How is there different versions of it like an IPS or a VA? How does that work? How does it compare to something like OLED or QLED?

Mostly marketing, there’s basically two main technologies to make screens (excluding e-ink): LED and O(rganic)LED. All these qled, miniled etc is just a variation of LED with different quality.
Although I fully agree with keeping it simple like that and I would state to anyone that this is basically correct, there are some technical differences between a ‘normal’ LED and QLEDs. And then there’s also Quantum Dot OLEDs which applies this ‘quantum’ (marketing term) layer to an OLED screen.
So in short, yeah they’re different but it’s indeed mostly marketing.
MiniLED is just FALD with more zones. OLED typically has the best image quality as each pixel is its own set of LEDs and no backlighting is required (FALD).
QLED has a quantum dot layer above the LED layer to filter the light. LEDs don’t make perfect red, blue, or green so the quantum dots transform the light into more perfect colors. You can even add a quantum dot layer to an OLED panel for better picture quality.
To make it even more confusing, microLED panels have individual LEDs per pixel. It is similar to OLED but without using the organic LEDs which would eliminate the burn-in OLEDs can have. As far as I know, microLED hasn’t made its way down to consumer televisions yet.
I see. Yeah it’s super confusing, but thanks for the explanations, really appreciate it. I wish microLED would be ready, cause right now there sadly just isn’t anything that can fully rival OLED on the picture quality, there’s a few super rare awesome LEDs out there but none on the level of OLED right now, and again very rare to find.
I definitely have major concerns about OLEDs as I recently got one and am anxious about that burn in, it’s a monitor and I’ll be using it as any other monitor per my needs so I’m a bit worried haha, I’ll try to take care of it obviously but I still wanna use it as a monitor.
Should I make another post somewhere asking about OLEDs longevity or?
Modern OLEDs don’t burn in easily. https://youtu.be/x0kh3_8OTmQ
They still seem to do if you push them which is what I’m worried about, using one as a PC monitor probably would qualify as you “pushing it” as you’ll inevitably have long periods of static stuff up frequently for hours, my use case definitely leans towards that rather then causal on and off usage.
it’s definitely gotten better overtime it looks like but it’s still very much a thing which I’m anxious about, not helped by how expensive they are, no idea how it’ll hold up for me.
Though I heard different organic compounds last longer and behave differently then others, do you know what 4th gen QD-OLEDs use for their pixels?
I’ve been using the Dell in the video daily for 2 years as a monitor and there is zero burn in. 4th gen has more layers in the oleds so they should have even better durability.
Congrats! What’s your use case like then? How long is it on for usually? Have you noticed any other issues like dead pixels or dimming or what else?
I was interrupted before I submitted this comment, and I see you’ve gotten some replies since I wrote the draft, but my comment goes a little deeper, so I figured I’d still add on.
FALD and mini LED are similar in function, but mini LED has a couple advantages. Since the actual LEDs are smaller, you can place a larger quantity of them behind the LCD panel than traditional LEDs. This allows for more dimming zones to reduce the halo effect, and also enables higher peak brightness which means better contrast.
IPS and VA refer not to the backlight system, but to the actual liquid crystal display panel that sits in front of the backlight. The LCD itself is like an array of microscopic window shutters that can turn clear or black. By placing this LCD behind a color filter layer, the LCD can control light passing through each subpixel (red, green, blue) of the filter layer to produce the appropriate color for each pixel. Each panel type (IPS, VA, TN, etc ) has its own set of advantages and disadvantages when it comes to cost, response time, image ghosting, viewing angle, color accuracy, contrast, etc. Each of those panel types could be paired with an edge-lit backlight, FALD backlight, or mini LED backlight.
OLED is a completely separate technology altogether. Instead of putting an LCD filter layer in front of a backlight, OLED puts individual white LEDs behind each red, green, and blue subpixel of the color filter layer. That means instead of a liquid crystal layer blocking out backlight (which is imperfect and still bleeds light, hence the FALD halo effect), an OLED simply does not emit light for that pixel/subpixel, allowing perfect blacks and better color accuracy.
QLED and QD-OLED trade the white LED backlights and white OLED panels for blue light and discard the traditional color filter layer, replacing it with a sheet of quantum dots that use some kind of black magic optical fuckery to change blue light into red and green as well.
No worries! It’s still very much appreciated, thx for the in-depth explanation!
‘Black magic optical fuckery’ I like those funny words haha.
Though one thing that I still don’t understand is why the Q stuff uses blue light over white light, I heard it’s supposedly better for colours or something? How so? Isn’t blue light in OLEDs especially the most likely to degrade first or something?
I also heard about different versions and tunings of the LCD panels that try to fix their inherent disadvantages, i.e. IPS black, Fast VA, etc. how are those made?
