QLED and OLED — What to Prefer?

 QLED and OLED — What to Prefer?

While searching for a perfect television, for sure you must have come across two most common terms that are, QLED and OLED. A non- tech person will simply ignore the mismatched letters Q and O. Little did they know that this one letter difference is enough to turn the tables. Here in this article, we will tell you the lows and highs of these two TV technologies. 

In case you want to know more about best TVs under 20k then go through this article.

What are QLED and OLED?

Before proceeding it’s important to know exactly what is QLED and OLED and why we are taking it into consideration. 


So, Quantum Light Emitting Diode (QLED) is more like a regular LED television. The major difference is that QLED uses tiny nanoparticles known as Quantum Dots in order to enhance its color and brightness.

If we talk about Organic Light Emitting Diode (OLED) then here every single pixel behaves like a tiny LED light. As each pixel is capable of producing its own light and color, therefore, OLED TV’s don’t need a backlight. In technical words, you can say that it has an ‘Emissive’ display.

QLED vs OLED: Which One is Best

Now we can compare these two technologies and on the basis of four categories which matter most.

Brightness: Here OLED can’t compete with the QLED even though they have improved over the years. The reason is that QLED TVs use distinct backlight instead of depending on individual pixels to generate their own light.

Black Levels and Contrast: OLED has the ability to go completely black whenever needed that is why when it comes to black levels OLED is unbeatable. As a result, unlike QLED TVs that are forced to dim their LED backlights, they don’t have to struggle to make bright parts brighter to achieve good contrast.

Color Space: Well in order to declare the winner of this category we need to investigate some noticeable difference. Presently, it is acceptable that both QLED and OLED deliver eccentric colors.

Response Time and Refresh Rate: Mostly response time matters during fast-action scenes. In simple words, response time refers to the duration pixel takes to switch from one state to another. It sounds good that QLED TV’s response time lies between 2 to 8 milliseconds but on the other hand, OLED’s response time is only 0.1 milliseconds. 

Next is refresh rate, that is the number of times per second TV updates the user whatever is streaming. It inherently matters more to people who love gaming. Moreover, the refresh rate is closely related to the frame rate and as long as the refresh rate is double the frame rate it will work seamlessly. Noticing an OLED’s greatness in this field, it wins this category.


Although both technologies are best in their own ways, if I have to choose one then for sure it will be OLED. With so many advantages, OLED is also suitable for eyes as it produces comparatively less blue light than QLED TVs. Well, all these points are enough to bring out the champion between QLED and OLED.
