OLED Vs. QLED TV: Which to choose and why

There are several different aspects to consider when choosing a new TV. The alpha and omega in this case primarily display technology. OLED and QLED are currently among the most discussed display technologies. In terms of names as such, they differ from each other in only one letter, but there are many more differences. Let’s work together in this article to compare OLED TVs with those of QLEDs and let’s say for whom display technology is better. What is QLED? Advantages and disadvantages

OLED, QLED, and others

As if all sorts of abbreviations were not enough. However, if you are going to buy a new TV that will last you several years, it is definitely worth doing a “survey” and finding out which display technology is right for you. However, if you do not have a lot of time for your own research, you do not have to worry about anything. We have created this article just for you, in which we will compare both display technologies completely objectively and impartially. After reading this article, you will know whether you should choose OLED or QLED. How does wireless charging work?


Before we dive into the comparison of individual aspects, it is necessary to explain how both of these compared technologies work. At the outset, OLED works quite differently from QLED. But that certainly doesn’t mean that one display technology is automatically better than another. In fact, both of these technologies have their advantages and disadvantages.

OLED stands for Organic Light-Emitting Diode. In Czech, therefore, it is a diode that can light up thanks to organic materials with the help of an electric current. This means that each diode, which is the size of one pixel (pixel), produces its own light. It is therefore not necessary to use backlighting as with QLED and other known technologies. Each diode can work independently of the others on an OLED TV, which brings a number of different benefits. If the diode is not used, it will go out completely. Due to the unused backlight, this means that the black color is really black in this case. OLED technology is mainly used by the LG brand, in addition to which also Sony, Philips, and Panasonic. Redmi K50i will be launched in India soon, special specifications revealed


QLED stands for Quantum Dot Light Emitting Diode. In translation, it is an LED that uses quantum dots (Quantum Dots, QD). QLED television is in a way built on classic LCD TVs, which are backlit by LED diodes. However, a kind of “enhancer” in this case is Quantum Dots technology, a special layer of highly resistant quantum dots, which is used to improve the overall image. In addition, this layer is complemented by special blue LED lights. This creates a highly clear image with support for more than a billion different colors. Behind Samsung’s QLED technology, you will find it mainly on TVs from this South Korean company. However, Samsung has teamed up with the TCL and HISENSE brands, which are not so widespread in our country. Together, these brands are trying to “stamp the OLED technology” into the ground.

Which technology to choose?

Together, we simply explained the difference between OLED and QLED televisions. However, what we lie about, the average user in the end does not care what the imaging technology is called. His primary goal is for television to meet his expectations and for him to watch it with joy every time. Therefore, below we will look at some basic aspects that need to be considered when choosing each TV. For these aspects, we will ask whether OLED or QLED technology has the upper hand.

Thickness and body as such

The first aspect we will look at is the thickness of the television. If you’ve ever had the opportunity to watch some of the latest TVs, you’ve found that they can be really narrow. Some TVs are even so narrow that they have their hardware separately in a separate box, so only the screen hangs on the wall. These extremely narrow televisions always have OLED technology. As mentioned above, OLED television does not need backlighting, ie the layer of LED diodes, which is necessary for QLED televisions. Of course, this layer takes up some space, so not only QLED TVs, but also all others that do not use OLED technology, are thicker. But it’s definitely not a big difference – we’re talking about centimeters. However, if you want to have the TV mounted on the wall, for example, and you don’t want it to protrude too much, OLED will be better for you.

Filing black

We have already mentioned in one of the above paragraphs that in the case of OLED technology, individual pixels can be completely switched off. Since OLED TVs don’t even have a backlight, this means that the black color is really black in this case – nothing is lit anywhere. With any other imaging technology, including QLED, black is never 100% black. It is a very dark gray, which the brain cannot fully recognize from black in the final. Contrast, ie a value that indicates the ratio between the lightest and darkest part of the image, is also related to the rendering of black. Given that OLED TVs have a blacker black color than the case of QLEDs, it is clear that OLED is better at contrast.


The first advantage of QLED is the presentation of colors as such. QLED televisions are the only ones that can display all the colors from the P3 gamut, specifically in this case we are talking about more than a billion different colors and shades. OLEDs, on the other hand, lose slightly, but this is not essential. Most OLED TVs can display more than 90% of all colors from the P3 color gamut. So if you are going to watch some color content, you can look forward to a slightly better presentation of these colors on QLED TV and, above all, better HDR support. As mentioned above, OLED, on the other hand, displays black as really black, resulting in better contrast.

Maximum brightness

In terms of maximum brightness, QLED technology has the upper hand. The explanation, in this case, is relatively simple. As already mentioned, in the case of OLEDs the backlight is taken care of by each diode separately, while in the case of QLEDs the backlight is solved separately by means of LED diodes. However, the individual small diodes cannot produce as much light as the strong backlight you find on QLED televisions. So if you plan to use a TV where there is always a lot of light – for example, where the sun will shine directly on the TV most of the time – then you should consider the advantage of QLED TVs. OLEDs are then suitable, for example, in the bedroom or in a “darker” room. In any case, keep in mind that you can always hide. If you put an OLED and QLED TV side by side, the brightness would probably be the first big difference you’ll notice.

Viewing angles

One of the reasons why users prefer OLED TVs over others is the viewing angles. OLED televisions have much better viewing angles than QLEDs. If you are going to watch TV from different angles, then you should definitely choose OLED TV. You can use wide viewing angles, for example, when watching sports in groups or if you want to watch TV in the living room from the kitchen. The OLED owes its better viewing angles to independent diodes (pixels), which do not need backlighting and can be switched on with an electric current. On the contrary, QLED televisions have to rely on backlighting, which means that the picture is not so good from angles.

Response and ghosting

Are you one of the individuals who like to watch sports? Are you going to play games on the new TV? Or do you plan to watch an image that is constantly changing? If so, OLED TV may be ideal for you. Compared to other technologies, they offer unrivaled response speed. Of course, this is not to say that you could see a worse response to QLED. It is only necessary to mention that in some cases, every single millisecond can play a role. Thanks to the low response, you don’t have to worry about blurring or so-called ghosting. In practice, ghosting can manifest itself, especially in fast-moving objects, which can leave “ghosts” behind in the event of a lower response speed.

With old plasma TVs, you may have encountered so-called burning after a long period of use. This is manifested when there is a fixed object in the same place on the screen for a long time – for example, the logos of television stations. As OLED televisions began to spread a few years ago, similar burning problems arose. The good news, though, is that you no longer need to burn OLED TVssolve. Several different steps have been taken to prevent burning. Most OLED TVs offer special functions directly in the settings, thanks to which you completely eliminate burning. For example, it is a function that moves the whole image unnoticed from time to time. It is now generally stated that you would have to have the same content on television for about four thousand hours to show the burn. This is not a problem for most of us. However, if you are afraid of burning, then in the case of QLED TVs, you do not have to worry. It cannot be burned here.

If you have decided to buy a brand new model of television, then you should know that in the same category, OLED will be more expensive in most cases. Prices can compare in a way if you compare a better QLED TV with an average OLED TV. Of course, there may be some special events that will allow you to buy OLED TV for a better price. However, if you are simply looking for a TV that has great picture quality but should be cheaper, you will need to reach for QLED. The price then also depends on the size of the TV, which you must determine yourself. Accountant job description

Conclusion and decision

Above, we looked at the basic differences between OLED and QLED TVs. Even though there are some differences between the individual technologies, both technologies are great and you will definitely not make a mistake with either. However, in the case of OLED, you can look forward to better black rendering, better viewing angles, and virtually zero response. In addition, OLED TVs are really surprisingly narrow, so for example, they will not protrude as much from the wall as QLEDs. QLED TVs then boast higher maximum brightness, and better color rendering as such, are not in danger of burning and are generally cheaper than OLEDs.

I chose OLED

If you have decided on OLED TV based on the above aspects, you can choose from several different manufacturers. But the truth is that LG is one of the most popular manufacturers of OLED TVs. In addition to LG, OLED TVs also offered by Sony, Panasonic, and Philips. In any case, only LG is able to create larger OLED panels. So if you are planning to buy a large OLED TV, you will have to reach for LG. So you can buy OLED TVs in various sizes from this brand – you can get TVs with a diagonal of 48 ″, 55 ″, 65 ″, and 77 ″ without any problems and for an acceptable amount. There are also larger ones, but they are mainly made to order and you will pay hundreds of thousands of crowns for them.

I chose QLED

If you have opted for QLED television, the choice is relatively easy for you. In the Czech Republic, QLED technology is mainly available for Samsung televisions. Of course, in some stores, you can also reach for TCL and Hisense, which are not so widespread in our country. Samsung offers many different TVs with QLED support, from small to large. Specifically, QLED TVs can be purchased, which are available in diagonals of 80 cm, 108 cm, 125 cm, 139 cm, 164 cm, 189 cm, and 215 cm.
