QLED or OLED: Which technology to choose for your television?

You are looking for a new television and are hesitating between QLED and OLED technologies? You are not alone! These two technologies are indeed among the most popular on the screen market today, offering exceptional image quality.

In this article, we will explore the main differences between these two technologies to help you make the choice that best suits your needs and preferences.

OLED: The reference in terms of contrast and deep blacks

OLED (Organic Light-Emitting Diode) is a display technology that uses organic light-emitting diodes to create the image. This means that each pixel emits its own light, without the need for backlighting. As a result, OLED screens are able to produce absolute blacks, since the pixels involved can be completely turned off.

Contrasts are extremely precise, as there is no light spill from a lit pixel to an unlit pixel. This results in a very detailed and realistic image, with excellent dynamics between dark and light areas.

The advantages of OLED:

  • Deep blacks and high contrasts;
  • Excellent overall image quality;
  • Wide viewing angle, no color degradation even when viewed from the side;
  • Thinner and lighter screens, thanks to the absence of backlighting.

QLED: Bright colors and impressive brightness

QLED (Quantum Light-Emitting Diode) is a technology developed by Samsung that uses nanoparticles called "quantum dots" to improve color quality. These particles allow for very pure and intense colors, resulting in an extremely colorful and surprisingly realistic image.

Unlike OLED screens, QLED screens use LED backlighting to emit light. They are therefore capable of achieving significantly higher brightness levels than OLED screens, which can be particularly appreciated in very bright rooms or when watching HDR (High Dynamic Range) content.

The advantages of QLED:

  • Very vibrant and accurate colors;
  • High brightness and excellent HDR performance;
  • Less prone to permanent screen burn-in than OLED;
  • Potentially longer lifespan due to material durability;
  • Generally less expensive than OLED, especially for larger screen sizes.

4K Resolution: A common asset to both technologies

It is important to note that both QLED and OLED screens are available in 4K resolution, which offers spectacular image quality.

4K (or Ultra HD) corresponds to a resolution four times higher than that of Full HD, allowing for a much more detailed and colorful image. Many contents, such as movies, series, and even video games, also benefit from this high resolution.

Choosing between QLED or OLED: A matter of preferences and use

Ultimately, choosing between a QLED or OLED screen will depend mainly on your personal preferences and how you plan to use your television.

If you are primarily looking for deep blacks and perfect contrasts, you will probably be more satisfied with an OLED screen. On the other hand, if vibrant colors and high brightness are essential to you, then QLED might be a wiser choice.

Other factors to consider:

  • Price: OLED screens tend to be more expensive than QLED screens, especially in larger sizes (see our article on converting inches to cm);
  • Durability: QLED screens may potentially last longer than OLED screens due to their resistance to burn-in;
  • Energy consumption: OLED screens are generally more energy-efficient than QLED screens, thanks to their lack of backlighting and their ability to completely turn off black pixels;
  • Availability: OLED products are currently offered by several manufacturers, including Sony, while QLED technology is mainly associated with Samsung and TCL.

In the end, the best way to appreciate the differences between these two technologies and their respective strengths is to view demonstrations in-store or at friends' homes. This will allow you to directly compare images and make an informed decision based on your visual preferences.
