Samsung has created a storm in the TV segment with its introduction of the new QLED TVs. The South Korean conglomerate is also leaving no stone unturned in its efforts to drive home the point how superior the QLED technology is compared to OLED. This naturally leads us to the pertinent question; how does QLED compare vis-a-vis OLED. Let’s find out.

QLED stand for Quantum Dot Light Emitting Diodes that, according to Samsung, stands for the pinnacle of TV viewing experience. And much of it has to do with the inherent technology used to render the images on the screen.

For instance, QLED TVs are based on quantum dots that have a different colored light to emit when light falls on it. The color of the light that gets emitted depends on the size of the dots. The larger is their size; more red will be the output light while the output light will tend to get blue if the dots are of the smaller dimension. In any case, the dots are just about a nanometer, which should give us an idea of how small a size it is being referred to here.

However, so much for the internal build, the one aspect where QLED can beat OLED hands down is its brightness aspect. QLEDs can have a peak brightness of anywhere between 1,500 and 2,000 nits. That is way better than the 1,000 peak brightness that used to be the norm in 2016.

Another aspect where QLED simply trumps the OLED is the former’s ability to reproduce cent percent color volume. As Samsung stated, QLED is able to handle DCI-P3 the most accurately which leads to the best possible color reproduction across the entire spectrum of brightness settings. In other words, color output remains equally vibrant irrespective of the brightness setting.

The ability to display vibrant colors which remain constant across the entire brightness spectrum also makes QLED naturally well suited to show HDR content. That apart, Experts also opine the QLEDs will be more cost effective compared to OLEDs.

Samsung is also showing off its latest QLED range at the CES event where an OLED TV is also kept at hand just to showcase how much of an improvement its latest QLED TVs have come to represent over the OLEDs. Those no doubt are showing curated content that Samsung has carefully selected to ensure the superiority of the QLED range is reflected in every which way possible. However, it remains to be seen how the QLED TVs actually fare in the market and in the long run.

QLED vs OLED: Which is better?

HDR and 4K Content Better than OLED Good
Energy Consumption Less More
Luminance 1500-2000 nits 1000 nits
Contrast Ration Good Better than QLED
Price Low High


  1. I’m not sure how you came to the conclusion that QLED is better than OLED for HDR and 4K Content. First of all, none of Samsung’s claims suggest QLED is better at 4K content. That’s just talking about the pixels – not the color accuracy. As far as HDR content, sure, QLED are brighter and claim to be more purely-color-accurate, but if blacks aren’t blacks, I see that as a glaring color inaccuracy – much more glaring than QLED’s claim of 100% DCI-P3 accuracy (btw, OLED are 101% of DCI-P3 accuracy, so I’m not sure what Samsung is bragging about). And if QLED is slightly more color accurate than OLED, I doubt most people will be able to see the difference, but anyone can easily see the glowing gray that passed for “black” on LED panels – and this will still be present in QLED (at least for the next 5 or 10 years, at which time QLED may be able to replace the backlight with individually lit pixels, much like OLED – but that’s a long way off). As far as brightness, put them side-by-side, and yes, the QLED can be turned up brighter, but in a dark room, I don’t want my TV brighter! I want more accurate color for watching in the dark. I have an OLED, and I have the brightness around 50%, which is plenty bright. Movie theaters are only a few hundred nits bright. This 1500-2000 nits is just Samsung trying to use specs to make their sets appear superior.

    So, I would say in terms of 4K content, you absolutely cannot say QLED is better than OLED, because that’s just talking about pixels, not color reproduction. And when it comes to HDR content, I think claiming QLED’s “better color accuracy” can be debated when compared to OLED’s pure blacks.

    • Hi Johnny5K,

      When it comes to 4K, QLED are better than OLED. I went to CES and saw with my own eyes at Samsung booth. They had both displaying 4K content and it was better on QLED.
