What Is An OLED TV? 5 Things You Had No Idea About

As their popularity is growing day by day, it’s time to find out what is an OLED TV. Basically speaking, OLEDs are those devices that don’t work with a backlight source inside, as most TVs do. That backlight isn’t neccessary because they create the needed light themselves.

But that’s just a preview of the whole explanation. 🙂



The term “OLED” is actually an abbreviation. It comes from “organic light-emitting diodes”, which means that these kinds of TVs don’t use the classic backlight as a light source. Instead, they use a carbon film which is placed between 2 conductors. That’s why they’re called “organic”.

In this way, the light is produced by the pixels themselves, not by any other external source.

Therefore, OLED TVs are those 4K televisions that work without a light source, because they create their own light once they are connected to electricity. Don’t get it wrong, OLEDs do need electricity, they can’t work without it. The difference is the way of using that electricity.



At this point, OLED TVs are the best ones on the market. At least when it comes to picture quality, which is way better than in any existing TV. However, they are also the most expensive types of TV, as you can’t find one below $2000.

But besides the great picture, what makes them so special among all the other televisions? It’s time to see the most important 5 facts you surely had no idea about.


1. Amazing Contrast Skills

OLED TVs are the peak of picture quality at this point, and here’s the explanation that lies behind.

Just like its definition states, an OLED TV is capable of creating its own light source inside, once it’s connected to electricity. This light source is actually not just one, but thousands. Thousands of pixels, that are in fact responsible for picture quality (that’s pixels’ usual part) but in OLED TVs, they also work as a light source.

So, as they basically are the light source, these pixels turn on and off by themselves. And they do it properly.

What’s the point of this? Well, it means that the shade of black created when the pixels turn off will be dark. Like, really dark. Darker than in other TVs that have a backlight inside as a source of light.

Well, it’s exactly the same thing when the pixels turn on – the shade of white will be much stronger than the one you see in other TVs. And this happens for every color in an OLED TV. Therefore, if we have (at least) 2 really strong, deep colors on screen, the contrast between them will be really strong too. And the image quality and clarity will be much more superior.

It’s not that hard as it seems, is it?

2. Super Fast Refresh Rate

If you never heard of refresh rate, you should know that it’s the period of time a TV needs in order to clarify the image, in case of some blurring. Obviously, this “period” is around milliseconds, so it’s impossible to test it without performant equipment.

An average OLED TV has a refresh rate of 120Hz, which is somewhere around 0.001 ms. Considering regular LCDs have a refresh rate of 0.01 ms, I think you can draw the conclusions alone. It may not sound like a big difference, but in terms of visual parameters, it definitely is.

And even though there are enough LEDs or LCDs with pretty good refresh rates and great overall picture, they still can’t reach the level of OLEDs.


3. Slimmest Ever

Because of the fact they don’t have any backlight source inside, OLED TVs are surely the tiniest on the market. In fact, you can’t find any that would measure OVER 0.4 inches. All models have at most a few millimeters wide, so they’ve been compared many times to a pencil head.

You can’t dislike the aspect of such a TV, that’s for sure. Besides looking really modern and elegant, it also seems expensive…not that it wasn’t.

And so far, TVs with similar width dimensions weren’t created. So if you want to get the slimmest available, an OLED is the only option. 😉

4. Really Wide Viewing Angle

Have you ever tried to look at your LCD TV from an angle? If you have, I’m pretty sure you didn’t stay in that position for long. Viewing angles remain the #1 problem of LCDs, and no company couldn’t find a permanent solution yet.

Most TVs have pretty bad viewing angles, no matter from what position you look, that’s quite a fact. I would say around 80% of them, and the other 20% probably have decent viewing angles (not good ones).

So most TVs pretty much suck at this chapter, but many of us may not have noticed. After all, who watches the TV from an angle? Seriously…

However, it is a parameter experts use in order to evaluate the features of a TV. And when it comes to an OLED, things are looking really good.

Because of the lack of a light source inside and therefore, of their thin screen, OLED TVs have a pretty clear viewing angle no matter from what side you look. Besides, as there is no backlight, the pixels are placed pretty close to the top, so the image quality will remain quite similar, no matter from how far or from what part you’re looking.


5. Reduced Power Consumption

The backlight of a TV is by far the biggest power drain, so it’s always recommended to set it lower if you want to reduce consumption. But what if there is no backlight at all?

I know what you’re thinking and that’s exactly the thing OLED TVs count on. As the backlight doesn’t exist, it doesn’t consume anything. The pixels used as a light source do consume, but not as much as a backlight. Besides, there’s the slim design of the TV, which also reduces the power consumption.

However, there are downsides too, and the main one is the contrast. The bigger the contrast of a TV, the bigger the power consumption too. So this takes back much the power saved by the pixels. Not all actually, because after the bottom line OLEDs will still consume much less than LEDs. However, the saved consume could get even better with time, so the future looks very good.

But until then, we can enjoy the visibly saved costs from now.


So The Conclusion Is…

…that I am personally a huge fan of OLEDs. And I’m sure most 4K lovers are, because these TVs really take the user experience to another level.

The amazing picture quality, the really modern design and the wide viewing angles  make them the absolutely best choice on the market. However, this big price manages to discourage some buyers. Unlike most LED TVs, an OLED isn’t something everyone affords at this point.

Anyway, OLEDs future looks very bright, and now that you know what is an OLED TV you can start keeping any eye on the market. Their great features will stay, but the high price will slowly decrease, so be ready for an amazing picture experience!

    I knew some facts about OLED TVs but I had no idea they had a higher refresh rate than regular TVs. So does this have anything to do with better gaming?

      Hello Phillip, they do have a faster refresh rate but this only leads to better pictures. In fact, it means the time this TV needs to un-blur an eventual image is smaller.

      Of course that the refresh rate is an important parameter in gaming as well, but the main one is the input lag. And in this case, OLED TVs aren’t necessarily better than every LED TV. This depends very much of each TV’s technical skills.

      If you need a great TV in gaming, take a look at this LED. It may not be very expensive or sophisticated, but it’s one of the best ones at this chapter
