You are currently viewing QLED, LED and OLED TVs: differences, advantages, disadvantages and which one is better for you

If you are looking to change your television and you have approached any store where they sell this type of device, you will have realized the number of options that you have at your disposal. Not only in terms of brands, but also in the different technologies they use in each of their screens.

All the different types of panel such as LED, OLED or QLED are different technologies that, despite the fact that they all look really good and have enormous capabilities for the vast majority of users, it is true that knowing how each one is Of them, it will be much easier to decide which is the best for us.

When buying any device, you have to know what kind of technology you are buying, especially so that later we don’t get any surprises.

We return to say the same thing that we have mentioned above, all these technologies have a lot of quality, but it may be that due to their parameters some of them are more suitable for what we are looking for.

The only way for us to be able to identify which is the most convenient panel for our purposes is to have all the necessary information on each of these types of panels, something that we are going to talk about next.

Led technology

In this type of technology we are basically talking about a flat panel with several layers that control light and color.

In this case, the bottom layer is usually always the backlight, that is, the one that allows the screen lights up so you can see the image.

As its name suggests, the lights used in this type of device are LED diodes (Light Emitting Diode)which are small electronic bulbs, the same as those seen in cars or in some traffic lights.

This means that we are dealing with televisions with LCD (those called LCD) but that, instead of using fluorescent tubes, they use the LED diodes that we just talked about.

One of its main advantages is its low consumptionso your durability is high.

QLED technology

We can talk about QLED technology, it is an evolution of the LED that we have just seen.

It’s based on the same principle of having a backlight, a liquid crystal layer, the color layer and the display screen, but instead of using white LED backlights, as that makes for less than perfect whites, uses a different technology.

The technology giant Samsung was in charge of creating this type of screen, which uses a blue backlight and then places a quantum dot layer between the backlight and the LCD layer.

These points are capable of receiving the blue light emitted and then turn it red and greensomething that by combining it allows to generate the perfect white backlight.

This whole system makes this type of television capable of offering the user a much more precise white, as well as more vibrant colors that are closer to reality.

The great advantage they have, compared to the LED, is that we get a better colouring, lower saturation, higher brightness and better viewing angles.

OLED technology

Its initials mean Organic Light-Emitting Diodewhich translated into Spanish is organic light emitting diode.

As you have been able to read, it is called organic, something that is like that because of the carbon film that you have inside the panel, just behind the glass screen.

It is a technology in which the emission of light is characterized by placing several organic films between driverswhich allows each pixel light up individually.

These types of televisions have two great advantages over others:

  • The first is that they can be much thinner and a lot more energy efficient than LED or QLED TVs.
  • The second is that, by having the ability to turn on pixels individually, if black is needed, they simply cut power to those pixels where black is present. So in this case we can talk about are the purest blacks of all technologies.


But then which one is better?

This is a question that is impossible to answer definitively, since each of the technologies has its positive and negative parts.

It is clear that if what we are looking for is picture quality we will have to buy a television with QLED or OLED technologyBut all this has its nuances.

If we have a quite limited budgetthere is no doubt that the LED televisions are the most suitable for us, since they are the most affordable models. Although they do not reach the quality of the other two technologies, their visualization is really good.

If we have already started talking about QLED and OLED technology, here each user must decide which is the one that best suits what they are looking for.

It is evident that the pure blacks who get the OLED technology and the energy saving, is something that QLEDs are not going to be able to match. But it is also true that despite the accuracy of color and contrast of OLEDs, they are not capable of having the bright that the devices with QLED display.

Also, the televisions OLEDs are more prone to image burncircumstance that occurs when the screen retains a static image, even if it is not there.

In this case, the budget will also say a lot, since OLED TVs are the most expensive on the marketsomething logical, since we are talking about those with better color and image quality.

Which one do we opt for?

It is clear that when buying any type of technological device, one of the most important assets is the budget.

We cannot enter there, since as we have already mentioned, if your budget is low you will have to buy an LED television, while if you do not have problems when purchasing your new Smart TV, you can opt for the QLED and in greater measured by the OLEDs.

But leaving the money issue aside, we can take into consideration that, as usual, the two most interesting screen technologies are QLED and OLED.

This guide that we have prepared with features, comparisons and best options by price range will help you choose the best SSD (both internal and external) for your device.

Here we can divide ourselves into two parts, that is, if what we seek is the best image qualitywe should definitely buy a OLED TV. but if what we are looking for is the best value for moneythen we must stay with the QLED display.

If you are curious to know what type of television this editor has, I will confess that it is a QLED type. I decided on this type of technology, since the living room of my house receives a lot of light throughout the day and a television with a really powerful brightness is needed.

Having said all this, you already have all the information you need to decide what type of television you want to buy. Now the type of screen it brings is no longer a problem, allowing you to also focus on other types of parameters.
