>QLED” is a backlit LCD technology
No it's not OLED is self lit, like pixel led lights.... LCD is "liquid crystal display" and needs back light shined onto it.
You are correct that Samsung has something even higher quality than that though, but it won't become standard for 10 years or so. It's not even on the main market yet.
Edit: backlit Screens can't fold and roll up like the new Phones, tablets and TV'S...... THEY ARE NOT BACKLIT BECAUSE THEY CAN DO ALL THESE THINGS.

This article makes some very heavy wrong implications.
LED TV’s only refer to the backlight, in fact, all TV’s marketed as LED’s are simply just LCD screen’s with LED backlights, instead of fluorescent backlights. This includes QLED display’s. LED and QLED TV’s are not “self emissive” where each pixel is it’s own light source, and these types of panels still require a separate light source. There are many different kinds of backlights found on these types of screens these days, including Edge Lit, FALD (Full-Array Local Dimming), and Mini-LED, are all different forms of backlighting technology, found in LED TV’s which use a Liquid Crystal Display.

OLED screens, on the other hand, are entirely “self emissive” where each individual pixel is it’s own light source, and can produce enough nits on its own to not require a backlight.
In practical terms an LED TV would mean each pixel is its own LED, but the industry at this point as I explained is only referring to the backlight technology of those LCD panels. The industry has coined an entirely different term for this kind of television, where each individual pixel is in fact, an LED, and capable of producing its own light.
This technology or panel type is known as “Micro-LED”, which is a very promising technology, however is still in the early “prototyping phase”. Displays can cost upwards of $100,000 USD currently, and are currently very large (over 100” for a 4K variant). They are currently now starting to produce sizes as small as 75”, but they are not 4K and close to HD/QHD. It will still be a while before you can purchase a 4K 60hz panel in a 65” at affordable prices.

You are still wrong my Dude.
OLED TV's exist, they are just Super expensive, And why we aren't talking about TVs. Most people don't have an OLED TV.
OLED literally stands for "Organic Light Emitting Diodes."
That's how OLED TVs like this exist.
Where is the Back light at? lol
OLED TV's are literally just self lit screens with a silicone matrix board behind them encased in plastic.

Micro LED is not OLED, it’s more comparable to mini LED but with individual pixel “zones”. Micro LED does not exist in the consumer space at this time. This level can be confusing, but you’re conflating a lot of the terms here. QD OLED is also distinct from QLED, the latter is not comparable to mini/micro LED or OLED technologies.

AMOLED IS NOT MICRO LED... What is your point and why bring up future tech completely unrelated?
>Micro LED does not exist in the consumer space at this time.
They exist in the Business space.
mLED is very new, and completely unrelated to this discussion. Apple and probably won't have mLED for the next 20 years that their current rate of adoption. Lol

I have an OLED TV, I own an LG G2.
An organic LED, and a traditional LED (non-organic) are two very different things.
A QLED screen is just an LCD screen, with an LED backlight, as well as Quantum dots within the LCD panel. LED TV’s are not “self lit” as you so claim, and all LED TV’s still use a backlight, while the panel is either a VA or IPS LCD screen.
The only two TV technologies that are self emissive are OLED (including Samsung’s QD-OLED, RGB OLED with quantum dot layer, and LG’s WRGB OLED, OLED with extra white subpixel), and Micro-LED (uses regular LED’s and Gallium Nitirde, rather than traditional organic compounds which are carbon based that deteriorate with use).
Mini-LED, LED, QLED etc all still use LCD panels, and backlights, and because of that are obviously NOT self emissive.
OLED (QD-OLED & WRGB OLED) as well as Micro-LED, are the only two self emissive technologies.
OLED & LED are two very different technologies and light sources. The OP you were replying too has been correct this whole time, you were the only ones who has the wrong info.

Im well aware that Apple still uses LED in their tablets. That's what this entire post is about.
OLED and AMOLED are self lit, as I have been saying.
I understand that some TVs have a backlight assist for watching in direct sunlight, But completely transparent screens are only possible because of OLEDs.

That is your quote sir.
You literally tried to argue that LED TV are self lit (they are not, the LED is in the backlight only) and that QLED wasn’t backlit LCD technology. Samsung makes a load of QLED TV’s, which all have backlights (either Mini-LED, or FALD). Only QD-OLED, does not have a backlight (again QLED and QD-OLED are two very different technologies)
True TV’s that use self lit LED’s at the pixel level (self emissive) would be mLED or Micro LED (hence why it’s called micro LED), which doesn’t exist yet in consumer form. Organic LED’s are not the same as regular LED’s and are two very different kinds of lighting technologies.

I meant to type OLED... You know, the thing that's being discussed? Like the last 2 comments you replied too?
You're basing your entire argument on a typo that's completely irrelevant to the discussion.
AMOLED is better than LED and LCD. THATS what is being discussed here.
AvengedFADE t1_j7jsz2x wrote
Man your the one who argued it, it’s not even a typo. You even presented a whole argument to the person you replied too.
Your confusing QLED and QD-OLED, that’s not a typo, your convoluting two different technologies as one..
QLED is backlit LCD technology, and your the one who wrote up a whole statement to the OP saying he was wrong. Currently there are no consumer self emissive LED TV’s, mLED is trying to change that (again an organic LED is not the same as traditional LED’s which use non-organic compounds). How is that not relevant to the conversation?
Edit: You can edit your comment and it’s still wrong, as the OP said QLED is just LCD with backlight, which it is.
Again QD-OLED, and QLED (which is what OP said), are two different things. QD-OLED doesn’t need a backlight (as OLED are self-emissive), but QLED’s do require a backlight, and are simply just LCD panels, with a QD layer and either FALD or Mini-LED backlighting.
He even said in the OP that QD-OLED is self emissive, you need to re-read the comment you responded too.

Dude you literally tried to dirty edit the comment, and make it seem like you weren’t wrong, but it still makes you wrong.
The OP you responded too was talking about Quantum Dots.
“QLED is a backlit LCD technology” is correct, no matter how much you try to edit or sugar coat it. You literally said “no it’s not.” The very person you responded too was talking about Quantum Dots, so I guess your wrong again.

QLED’s are Quantum dot displays. That’s what the Q in QLED stands for.

Do I really need a dictionary definition to explain this? If your going to argue about it with someone, then clearly it’s important to the conversation to correct someone when they are wrong.

You can't even keep up with your own comments, I don't expect you to keep up with what I'm telling you.
No one is talking about QD other than you. I don't even know why you brought it into the conversation unless you just want to make an example of more technology Apple won't have.

QD OLED’s are also quantum dot displays, QLED’s are also quantum dot display.
QLED’s are LCD panels with a quantum dot substrate, and an LED backlights (either FALD or mini-LED).
To quote PC mag definition “QLED (Quantum dot LED): A display technology that uses phosphorescent crystals to improve the LED backlight on an LCD TV.
https://www.pcmag.com/encyclopedia/term/qled
QD OLED, are OLED panels, with a quantum dot substrate applied. The OLED transistors are capable of their own light (blue light), and hence do not require a backlight, and the QD are what create the red and green light.
Pc mag definition “QD-OLED (Quantum Dot OLED): An OLED display technology that uses quantum dots as the color creators. When the blue backlight hits the red and green quantum dot subpixels, red and green are generated. Because blue is the backlight, it serves as the blue subpixel. See quantum dot.
https://www.pcmag.com/encyclopedia/term/qd-oled
QD OLED, and QLED are two different display technologies entirely. However Quantum Dots themselves can be applied to more than one screen technology, both LED/LCD TV’s and OLED’s can benefit from this technology, and does not refer to the panel type itself. It is simply a coating.
If your thinking of TV’s which use the quantum dots themselves as a light source (no need for OLED’s, LED’s, LCD’s or a backlight entirely), these are known as NanoLED, or EL-QDLED (Electroluminescent Quantum Dot LED) named after the creator of the company who makes Quantum Dots, Nanosys.

It’s truly hard to keep up with your lack of knowledge on this subject to be completely frank.

I'm saying they're completely irrelevant to this conversation and your entire argument based on irrelevant information.
You want to talk about quantum physics while we're here too?
Nothing you have said has anything to do with AMOLED or mini-LED BEING USED IN TABLETS.

It’s not irrelevant to the conversation, when your the one who tried arguing it in the first place. Like I’m not an expert in quantum physics, but we’re talking about TV’s here man, hardly a complex subject, but you tried to come out like an expert, and then argued this
OP - “QLED” is a backlit LCD technology (True)
AadamAtonic - “No it's not LED is self lit, like pixel led lights.... (False when talking about TV’s/display technologies). LCD is "liquid crystal display" and needs back light shined onto it.

That was wrong bro, just admit it. Even changing your sentence to OLED from LED still makes it wrong.
