Is QLED better than LED

QLED vs. OLED: Which TVs are Better?

If you want a new high-end television, you currently have the choice between two display technologies: QLED and OLED. The advocates of both worlds of course rave about the respective advantages. But how do they differ and which technology is ultimately really better for which application? We compare that here for you.

What is QLED?

QLED is not a new technology in itself. It is based on LED technology, which Samsung has added so-called quantum dots. LED televisions work with a backlight. Various filters are placed over these to block out the light at certain points. This is how the finished picture is created on the television. With QLED televisions, another layer, the quantum dots, is placed over the existing LED filter.

The Quantum Dots ensure that the television can reproduce even brighter images than the already bright LED TVs. In addition, this should make the black areas darker, which has always been a problem with LED technology. Often black tones look gray rather than pitch black. As a third advantage, more colors can be reproduced with Quantum Dots than with conventional LED televisions.

The term QLED was created by Samsung. The Korean electronics giant was the first to market televisions with the term. It is certainly no coincidence that QLED and OLED sound very similar. Samsung itself has been testing OLED screens for a long time and uses them primarily in the much smaller smartphones that it manufactures itself. With OLED in TV sets, according to their own information, they had not had good experiences and therefore reoriented themselves towards QLED.

With Hisense and TLC, there are now two other television manufacturers on board that want to make QLED big. The three electronics heavyweights call it the "QLED Alliance" with which they want to declare war on OLED. But is QLED really the better technology for televisions, or at least as good? That is controversial.

What is OLED?

In OLED technology, millions of these organic light-emitting diodes are arranged in a network. When these OLEDs are now supplied with power, they light up. The more power they get, the brighter they get. This is how the finished picture is created in the end. The biggest difference to QLED or LED is that the OLEDs light themselves and therefore do not need a backlight. This has the advantage that black areas are really black, which creates a rich contrast.

OLED is a very versatile technology that can be used to produce many different types of displays. If you want to know more about it, I can recommend our article to you, in which we explain different types of OLEDs.

The first TV manufacturer to introduce OLED TVs was LG. And for a long time the Koreans offered OLED televisions exclusively. This was also due to the initially very high prices. In the meantime, however, numerous other manufacturers also have OLED televisions on offer, such as Sony, Loewe or Philips. And prices have slipped sharply.

Which technology is better now?

If I want to buy a new TV now, should I get an OLED TV or a QLED TV? The question is not that easy to answer - of course, both technologies have advantages and disadvantages. In the end, it depends on your personal preference and possibly also what you want to use the television for.

Update: There is now a combination of both technologies - quantum dot OLED.

The advantages of OLED TVs

As already mentioned, one of the biggest advantages of OLED TVs is the high-contrast picture, which is created by the rich black tones. Since OLED does not require a backlight, the OLED diodes are completely black when not receiving power. For many, this is one of the most important factors when it comes to a good television picture.

The response time with OLED TVs is also faster than with QLED TVs. The response time is the time it takes for the diodes to turn on or off. A quick reaction time ensures that the picture appears overall “crisper” and sharper, especially with fast action scenes. A fast-reacting TV set is also important for gamers, as it means that the overview is not lost so quickly even with action-packed titles.

Another advantage of the self-illuminating OLEDs is the viewing angle. The image can be seen from almost any angle, as the light is emitted by the diodes, instead of being blocked by a backlight as with QLED or LED. This is an advantage if you have a large living room and the couch is around the TV. In this case, not every seat has an optimal viewing angle to the television, but with an OLED this should no longer be a problem.

When it comes to energy consumption, OLED is also one step ahead. Since there is no need for a backlight that has to be permanently lit, the energy consumption for OLED TVs is lower than for QLEDs or LEDs.

The advantages of QLED TVs

When it comes to brightness, the point clearly goes to QLED. Even LED TVs are brighter than OLED TVs; with the extra Quantum Dots, the image of QLEDs can be even brighter than that of LEDs. This increases the contrast, as the diodes do not lose any of their color even with more brightness. This is a great advantage, especially in well-lit living rooms, as a brighter picture can be seen better here. If the contrast is also right, you have the best overall package for bright rooms.

When it comes to very large televisions, QLED has an advantage. LCD panels can also be produced in large sizes without any problems. LG presented an 88-inch OLED television at IFA 2018, but it was a prototype and by no means ready for the sales halls. Samsung was able to score with an 85-inch 8K QLED television that is almost ready for the market. So if you're after a really big TV, QLED is a good choice.

While images can burn themselves into OLED TVs, this cannot happen with QLED TVs. For most TV viewers this is not a problem anyway. Only if an element appeared in the same place on the television for ten or more hours a day for weeks could a certain element be burned in on OLED televisions. But that happens extremely rarely. QLED has the advantage that images cannot be burned in there. So if you want to protect yourself from this, QLED is a good choice.

Conclusion

I think OLED TVs offer greater advantages overall. Especially for me as a gamer, the fast response time and the crisp picture are interesting. But that doesn't mean that OLED is a better choice in every situation. QLED shows its strengths especially in well-lit living rooms. Both technologies offer good picture quality with their own strengths and weaknesses.

By the way, neither technology is a bargain. With the exception of special offers, you haven't received either QLED or OLED televisions for less than 1,000 euros. Movie buffs are well worth the extra charge.
