Samsung QLED TV Technology Explained

Here’s an interesting topic that I felt would be worth talking about today; what exactly is Samsung QLED Technology? Unless you’ve been living under a rock for the past few years, then you’ll know that Samsung is now one of the biggest innovators and brands in.. well come to think of it, a lot of things!

In what seems like the blink of an eye, this once small South Korean company has managed to become a household name across the globe. From appliances to smartphones, they seem to be a powerhouse. Even when it comes to televisions, their reputation certainly precedes them.

Whether it be introducing the world’s first bezel-less curved TV, or winning over 100 awards in a awards single show, they’re no strangers to breaking the mold. So wouldn’t you know it, they’re back again with something new; QLED.

What is it though exactly? Let’s find out.


What’s The Name Mean?

QLED is actually an acronym, and stands for quantum dot light emitting diode. (Woah!) I know. But it’s actually not as complicated as it sounds.

The quantum dot part of it stems from Samsung’s own quantum dot technology from a few years back (meaning that it’s just technically the next iteration of this) and that last part is just a fancier way of saying LED.

So though this is still technically an LED TV; it’s their improved version.


But What Is A Quantum Dot?

I know by now you’re probably wondering what a quantum dot even is, so bear with me. To put it simply, think of these as extremely tiny particles each capable of producing light.

This small size though is what allows for them to have great accuracy.

You see, in many televisions today, there are white LEDs that while bright, have trouble producing adequate saturated colors. Quantum dots on the other hand utilize blue LEDs by transmuting the light they emit into their own, depending on their size..

This variation in size at essentially the microscopic level is what allows quantum dot displays to be more colorful, brighter, and more accurate.




QLED Has Actually Been Around Since 2014

So if these have been around for years, why is it being touted as new? Well because it is…in a way. It’s technically been around since about 2014, but was originally scrapped a little while later in lieu of working on other display technologies.

However in 2017, they resumed working on it again because they felt the current generation of TVs still had limitations.

Point is, this is Samsung’s 3rd version of it’s signature series that manages to bring with it some pretty important changes.

To appreciate those changes though, we would first need to understand how it works.


How Does QLED Work?

Alright, how’s it work? Well remember that little tidbit earlier about quantum dots with how they change color depending on their respective size? That’s exactly how.

They’re placed so closely together that they create a film that would then go in front of the backlight panel. This film is what dictates how things look depending on how many of those dots are actually active.

Also this time, each one has also a new, thinner, aluminum inside and outside that lets more light pass through it. This increase is what allows the screen to be brighter, as well as more colorful (very much so in person)

In fact, it’s able to display so many colors that it covers 100 percent of the DCI/P3 color spectrum; that’s over a billion for the unaware.

In other words, it’s able to display every color that the human eye can possibly see, becoming the first display technology capable of doing so. Quite impressive to say the least.



What Are The Advantages?

By now you’re probably thinking there has to be some pretty large benefits here, and you’d certainly be right. The first thing QLED allows for is a higher saturation.

This is due to the fact it can cover the entire color spectrum which is pretty impressive in my opinion.

In turn, this can make for images that are dramatically more vivid and intense.

Having a QLED TV myself, the colors and just how deep they looked was definitely one of the first thing I personally noticed.

That said though, what good is a more colorful image if it isn’t accurate?

Which is why the next advantage ties in with the previously mentioned one, in the form of its color accuracy.

Being more accurate in this regard can give a more realistic image, and the benefit of that is pretty obvious. You get scenes that look how they would in person, which further adds to the immersion.

The next advantage is one that’s two fold. First off, QLED allows TVs to get much brighter than they could previously, reaching a peak brightness of up to 2000 nits.

Think of nits as units of luminance; meaning the higher the number, the brighter the image. For HDR, another prominent display technology, at least 1000 nits is required to be shown properly.

So with just about double that, HDR content will look downright amazing.

It doesn’t stop there either, as not only is it able to get brighter, but it’s able to retain color accuracy at a higher brightness as well; a hard task to do for most other television sets.

Yet another plus for QLED (there’s a lot) is that because of the way it’s structured inside, it gives viewers much better viewing angles as well. That’s huge.

I’m not sure if you’ve ever noticed, but if you try and look at your TV from the side, you’ll see that the picture quality fades the more off center you go. This can sometimes make it hard to see certain details.

That’s no longer the case here, meaning you don’t have to sit directly dead center in front of the TV to get the best picture. That also means the people watching with you off to the sides a better image as well; so it’s really a win win.


What Are The Disadvantages?

However with all of that being said, in this case, there aren’t too many drawbacks. To be frank, only thing to mention would be given the fact that it still relies on a backlight (albeit a much improved one) black levels may still fall ever so slightly behind something like say OLED, where individual pixels themselves produce light. But even then it depends.

Actually, that perfectly segues into the next question…



If you don’t know, OLED is the other competing display format that’s been around for quite some time now. It’s major draw is that it doesn’t rely on a backlight at all; instead opting for each pixel to have the ability to shut itself off completely.

The result of that speaks for itself, with black levels that are essentially infinite. It’s also able to provide for more saturated colors as well, making the image look nothing short of breath taking. So with that, Is QLED better than OLED? Well both yes and no. It depends on how you look at it.

Truthfully, speaking from experience of having seen both of these in action (and even side by side at that) the black levels of the OLED seemed slightly darker.

Now I say ever so slightly because it was the first time I’ve ever seen a backlit display coming that close to matching OLED. If you weren’t comparing them side by side though, I’d venture to say that you’d be hard pressed to notice any difference at all, all things considered.

That’s an amazing feat in of itself.

But besides brightness, which is especially important for HDR content, this is coupled with incredible black levels which provides for a great picture quality which both have.

Another benefit has to do with color accuracy. In extremely bright scenes, OLEDs may skew in the way of color accuracy, whereas QLED, can maintain that composure though it depends too.

QLED TVs may have an advantage over the competition in the form of longevity

Given the fact that OLED displays use special chemicals that react to electricity opposed to a dedicated backlight, the longevity of the image may depend on how often it’s used when it comes to burn in.

Though QLED is still technically an LED TV that uses a backlight, they don’t tend to be susceptible to burn in because of that.

Burn in is an issue where an image essentially gets burned into the display that becomes visible during any viewing material. This is most common with things like logos in the corner or dark text on a lighter background.

Now mind you, that has been greatly mitigated in recent years due to advancements, and is much harder to happen now, it’s still technically possible.

But even then that’s if things are left on screen for long extended periods of time without moving.

In any case, it’s just nice to know that manufactures are tackling this issue head on, and coming out with displays that don’t really have to worry about this as much.

I also noticed that the OLED did happen to have a slightly better viewing angle as well, so that’s something else to think about. Also because of their lack of a backlight, they provide less energy consumption too.

So for the original question as to which is better, you can see that it really depends. In my opinon, just from what I’ve seen, I feel OLEDS strong suit is black levels, whereas QLEDs is its colors and brightness but that can and may vary.


Is it Better Than Their SUHD Range TVs?

In my opinion, I feel that QLED is an improvement over their previous flagship range SUHD TVs. They are able to get brighter while remaining more colorful, providing for a better presentation overall.

The UHD part stands for Ultra High Definition, and the S stands for superb (not Samsung surprisingly).

So when you put it together, it stands for Superb Ultra High Definition. It also stands for 8 other things including smart, special, and striking.

The point is, the switch from SUHD to the “quantum dot” is more of a marketing thing if anything, with the difference between them being the upgrade on their already existent tech.


What Is The Best QLED TV?

Winner: Samsung 65-Inch Class QLED 4K Q80C Series

If you were curious on which one I would personally recommend, it’d have to be this one. The Samsung 65-Inch Class QLED 4K Q80C Series is really is an amazing TV.

Besides offering everything you’d expect from a high end TV like 4K, HDR, etc, It also utilizes the awesome quantum dot technology we talked about earlier that really makes things look incredible.

This is the kind of TV where you’ll find yourself watching all kinds of shows just to see what it looks like (I know this was the case for me)

It really is breath taking honestly.

Final Thoughts

Hopefully you’ve enjoyed this article on Samsung QLED TV technology explained, and that it helped in the way of actually understanding this new tech.

Having personally seen the tech up close myself, (considering I have one) it really is nothing short of mind blowing in my opinion. It’s one of those things where you really have to see it to believe it.

What first started as a few TVs here and there has evolved into a point where a large portion of Samsung TVs now utilize this cool technology.

Plus with technologies like micro led & even 8K resolution, it seems like visual tech is always pushing forward in some way.

That wraps it up for this one though.

Until next time, make it easy, keep it simple. ?
