What Is QLED? How The Next Samsung Quantum Dot TV Tech Compares To OLED, SUHD [Explained]

What is QLED TV Tech?

When asked, Samsung explains about its new range of QLED TVs, where that stands for Quantum Dot technology rely on an LED panel. Simply way to digest is, quantum bot + LED = QLED. Replaces SUHD (Super Ultra High Definition) at the top of Samsung’s TV line-up in 2017, which Samsung bets big on QLED with launch of new range of TVs. How does it work? And how does it differ to OLED is in question.

At a launch event in Paris, Samsung officially announced the global launch of its new ear of OLED TVs, actually were first showcased at CES earlier this year. A new type of TV technology that could prove to be a major leap forward in picture quality, which it’s been called the QLED, which isn’t somewhat you may think is incredibly similar to OLED. Samsung;s QLED TV family of new devices promises to be more capable than any of its previous range of TV models. This isn’t anything new tech, rather it’s the third-generation of quantum dot in Samsung’s TVs, so you’ll also find it in the 2015 and 2016 SUHD models, although in the new QLED 2017 models, with a lot of changes.

Originally, it’s being pitched as a rival to OLED (organic light emitting diode) at the high-end, with Samsung pushing the message that Quantum LED is a superior technology with a number of advantages over OLED. There will be on-going battle for superiority between LED TV and OLED TV.

Changes and quality features when talking about. Not only does QLED as an expression look like OLED, but it also resonates better than SUHD, which didn’t really mean anything. Also allows Samsung to separate its flagship Q models, from the second-tier models it offers. LG, on the other hand also uses quantum display, but in a different way, which we will discuss about later.

How does QLED work?

Quantum dot TV technology works by placing a layer or film of quantum dots in front of a regular LED backlight panel. The layer which is made up of a tiny particles each of that emits its own individual color depending on its pixel size (between 2 and 10 nanometers). Generally, the size of the particle dictates the wavelength of light that it emits, also different colors. In this part, Samsung boasts that quantum dots enable over a billion colors.

With the third-generation quantum dot TVs, called QLED, the particles have now been changed. They have a new metal alloy core and new metal alloy shell. This enhancement has enabled greater color accuracy but also enables that accuracy at higher peak brightness. Something like 4K HDR+?


The ability to produce these colors at higher brightness gives a greater color volume than before and it’s here that QLED claims to surpass the abilities of OLED. It is capable to preserve colors in peak brightness areas that OLED can’t and those peak brightness areas are also higher than OLED can currently achieve.

Result is legitimate, QLED gives you a lot more visible color, better suited for vibrant delivery of HDR content, thus claims to be able to better give the visual experience that director intended.

The only different between QLED versus OLED is that, the two technologies apart. Quantum dot TVs still rely on an LED backlight system working in zones, but OLEDs each produce their own light. Only advantage that OLED offers is that you can turn off the pixels that aren’t needed, giving an absolute black areas with no light bleed caused by the need for illumination in some part of a dimming zone, theoretically.

While Samsung’s QLED models all use an edge-lit LED system and is divided into dimming zones. The flagship model, the Q9, has 32 dimming blocks, whereas other ‘Q’ models have 12 and these are used to control the light. Here, the more dimming blocks could be better for delivering different light levels in different areas on the screen.

When compared, the OLED screens can effectively produce better blacks, quantum dot TVs can still go much brighter, that too you throw High Dynamic range (HDR) into the mix, brightness is key then. New OLED TVs in 2017 are much more brighter than 2016s, but still some way off LED.

OLED screens are still considered to be expensive compared to their LED counterparts, because OLED screens are still relatively difficult to produce, although yield rates are much better than they were in the past when the technology first emerged into the market.


Before we give any answer, you must also know the difference between SUHD and QLED panels. Samsung’s new QLED screens can reach peak brightness from 1,500 and 2,000 nits (the 65-inch Q9F can reportedly achieve 2,000 nits), leaving OLED screens very far on the back number when it comes to brightness.

Impressed by Samsung’s KS series of SUHD TVs in 2016, but QLED is a confident step up the ladder. They offer better picture quality than Super Ultra High Definition (SUHD), the colors appear to the richer and reflections and viewing angles are also better. This, combined with increased brightness, making it for an impressive package.

Samsung’s QLED is a technology that not only rivals but exceeds the capabilities of OLED, so we suspect the prices might be fairly close or go higher.
