QLED and OLED TVs: 7 Key Differences

QLED and OLED technology has opened up a new era for television. Both use different technologies to offer an amazing TV experience. However, as their name is quite similar, but they are different in many ways. If you are now confused between these two TV, here are their 7 key differences.


QLED stands for Quantum Light-Emitting Diode. Basically, the QLED TV is just like a conventional LED TV, except it uses quantum dots embedded in an LCD panel. These tiny nanoparticles significantly improve color and brightness in comparison with non-quantum LEDs/

OLED stands for Organic Light Emitting Diode. Every pixel in an OLED TV is also a tiny LED, extremely thin, and can produce both light and color in a single element. In other words, OLED TVs don’t need backlight because each pixel produces its own light.

Black Levels and Contrast

Contrast is the difference between the darkest and lightest parts of an image. A TV can produce the black and white parts properly, that’s a good TV. What separates OLEDs from traditional LCD or LED display lies in its ability to balance black and white levels. In other words, the pixels in an OLED TV display are able to turn off the light completely when they need to be black.

On the other hand, QLED TVs create true black images by dimming the LED backlight while blocking the rest of the light.


Compared to OLED, QLED TVs have an advantage in brightness because they use a separate backlight instead of relying on each pixel to create their own light. The LED backlight can be produced with extremely high brightness. In addition, QLED TV’s quantum dots have the ability to maximize that light by producing brighter colors in the color spectrum without losing saturation.

Color Space

There was a time when OLED led steadily in terms of color space. But the adoption of quantum dots has helped QLED TVs boost display accuracy, brightness, and color range. In fact, both technologies are even in terms of color space now.

Response Time

Response time refers to the time it takes a pixel from one state to another. The faster the response time, the sharper the image is, especially in fast action scenes. To be honest, you cannot see the difference in response time with the naked eye. Based on standard measurements, OLED TVs are much faster than QLED TVs.

Response times on conventional QLEDs fluctuate between 2 and 8 milliseconds, which sounds pretty good until you realize that OLED’s response time is only about 0.1 milliseconds.

Power Saving

OLED TVs use ultra-thin OLED panels and do not require a backlight. As a result, they are usually lighter and thinner than QLED TVs. This means that OLED TVs are more energy efficient.


Due to the high production cost, the selling price of OLED TVs is somewhat higher than that of QLED TVs. You can find deals for a good 4k QLED TV for just under $1000. Meanwhile, OLED TVs typically cost $1200 and can go up to $30,000.

There you go, now you know about the 7 keys differences between QLED and OLED TVs. We hope that this article can help decide which one is right for you. If you have any questions, please leave them in the comments!
