When buying a television, the technology of the screen is essential. Well, after all, that is what determines the quality and the experience in the different scenarios.

That is why we are going to tell you the differences and similarities of the most common technologies on the market. These technologies are as follows:

  1. Led

  2. QLED

  3. OLED

So keep reading to see the pros and cons of each one and make the best purchase possible, according to your criteria and needs.

LED screens

These acronyms stand for Light Emitting Diode, it is a technology that arose before the other two, and basically it is about using LED as a backlight to illuminate an LCD panel.

QLED screens

In essence, they are the same as LEDs, but with one big difference and that is that between the LCD layer and the backlight, there is a layer of quantum dots that filters the light to produce more pure and saturated colors.

So, the results are better in the greater range of colors, and here we make a parenthesis, since the QLED and LED televisions we find the UVA type and IPS type panels.

UVAs provide a great contrast ratio and good black uniformity, at the cost of poor viewing angles. Usually that is what we see on many Samsung TVs.

That is why this type of panel is the best for poorly lit environments, while IPS-type panels basically stand out for their excellent viewing angles and good brightness, with the cost that blacks are rather somewhat gray and therefore the ratio of Contrast is not very good, and they falter in dark settings.

Here we find many LG TVs that are ideal for brighter environments.

OLED displays

It is a technology that is very different from the previous two, since instead of using LED backlight, they have pixels that light up automatically and can be turned off when necessary.

Therefore, you have surely heard that with these screens the blacks are perfect, deep and there are more energy savings, as well as good viewing angles.

With these concepts clear, you will surely think by now that OLEDs are the best, then QLEDs follow and finally LEDs.

But you have to take into account other fundamental factors that we have not talked about, so that you can build your criteria in a better way and know which one is better for your case.

Below we will analyze these technologies in the different sections, to determine their pros and cons.

Black level

At this point, QLEDs and LEDs are very similar, since they use the same technology with backlighting. Here it should be noted that most use UVA panels, as they have a high contrast ratio and good blacks.

Even on high-end models there is a local dimming function that deepens the black level further.

However, these screens can not do anything compared to OLEDs, since the latter have a perfect black level as each pixel can be turned off individually. So, the results are amazing, in this regard, a point for OLEDs.

Single color uniformity

In this section it is determined that a screen shows only one color. LEDs and QLEDs have some trouble showing a completely uniform color, as you can see in both there are imperfections on the sides and edges.

While OLEDs provide a better one for the issue of independent pixels, since QLEDs and LEDs depend on the backlight, which is damaged, causes major uniformity problems. In this sense, it is again point for OLEDs.

Brightness

Regarding brightness, things change, since both QLEDs and LEDs take advantage of the LED backlighting that allows them to maintain maximum brightness in different content.

Whereas OLEDs have an aggressive automatic brightness mimic that limits screen brightness. So to see HDR content with better results, the QLEDs and LEDs are the winners.

Color range and volume

Regarding the range of colors, it is the great advantage of QLEDs compared to LEDs. This is how QLEDs are better than LEDs and OLEDs. By combining its wide color gamut with the brightness level, a good volume of color is the result.

It should be noted that OLEDs are good, but they lose in this section due to having problems showing bright colors.

Viewing angles

Regarding the viewing angles, the question is simple, since OLEDs have independent pixels, they emit light in all directions. This results in very wide viewing angles, making the image look great when viewed from either side.

So they are ideal if you want to watch television in a group. As for LEDs and QLEDs, this is where IPS panels outperform UVAs in this regard, by providing good viewing angles.

Although the brands have improved lately, to make their UVA panels better in that regard. Samsung, for example, has a technology that helps the viewing angles to be better.

Image retention and burning

Regarding the image retention that occurs when a fixed image is left for so long that the screen cannot fully release that image, it should be noted that it is the Achilles heel of OLED screens.

Well, leaving the same image on the screen for about 10 minutes can sometimes leave a dim version, something like a ghost. This being most noticeable with uniform colors, yes, it is something that takes a few minutes to completely disappear.

On the other hand, although QLEDs and LEDs are not totally immune to this, it is clear that it is something that rarely happens on these screens, if not ever. This is where the famous burn issue also comes in, which unlike image retention, is permanent.

So the entire screen is literally thrown away. As you may think, this is a common problem for OLEDs, about whether they use as PC monitors, where there are a lot of static elements.

However, this should not be a problem if you are looking at varied content. In addition to that, companies have done everything possible to reduce the risk of burns with some options.

But in any case, if you are going to use your TV screen as a PC monitor, an LED or QLED panel is better.

Motion blur

When looking at different screens, you may notice that moving images react differently on each television. This happens because of the famous response time.

At this point OLED technology takes advantage, since each pixel can be turned on and off individually, thus generating an almost instantaneous response time.

This results in movement that looks extremely smooth and there is almost no motion blur. Of course, it should be noted that the results on the QLED and LED screen are not bad. But OLED technology puts them ahead.

Price and availability

This is a crucial section for everyone, price and availability. Here it should be noted that OLED televisions have dropped considerably in price, if we take into account what it cost in previous years, only a few pockets could afford it.

The point is, nowadays, there is not much availability of them, since most of them are manufactured by LG, and they are large. So you must imagine if or if you have to pay a considerable amount of money.

This is how the kings in terms of quality-price are the QLEDs, because they have a lot of availability and options in the market, especially in brands such as High 6 and TCL, where they are cheaper.

The same occurs with LED televisions which are located in the entry level and the mid-range and therefore are accessible to all types of public.

Conclusions

As you already realized, each technology has its advantages and disadvantages. It has become clear that QLEDs and LEDs are very similar in technology, and that the great plus that QLEDs have is that they have a wide range of colors. So the end result is more amazing.

Meanwhile, OLEDs do have a different technology than these two, since they have pixels that can be turned on and off individually. Resulting in deep blacks and wide viewing angles.

However, QLED and LED TVs tend to be much brighter, and due to the brightness and wide range of QLED colors these are better options for consuming HDR content.

Therefore, if you plan to buy a television to have it in a large room, to watch movies, with a group of friends where viewing angles are very important and quality is of course also important, OLEDs are your best option.

But if what you want is a television that you are going to use as a PC monitor from time to time, it is better to cure yourself in health and lean towards a QLED or LED option, since OLEDs have this problem of burning with static images.

Factors you should consider before buying a television.
