QLED” is a backlit LCD technology

“No it's not LED 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.”

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.

That's what I said...

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.

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

"MINI LED^^backlite** DISPLAY! "

They use clever marketing to trick you. The LEDs that light up the LCD screen are mini... The LCD screen itself is not a mini LED screen..

The iPad Pro 12.9 uses bullshit words like " liquid retina XDR display" which is just fancy for saying, "Liquid Crystal half-assed Hdr Display. (LCD/LCxD)

Ipads and iphones still stuffer from Burn in like old ass TV's.

This is another reason Apple is changing their screens finally.

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.

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.

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.

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.

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.
