QLED vs OLED – Which Is Best?

OLED displays offer higher contrast ratio, faster response time, wider viewing angles, and better colors, but lower brightness than QLEDs.


OLED displays offer infinite contrast ratio, instantaneous response time, wide viewing angles, and superior color accuracy.

However, they cannot get as bright as QLED/LED displays and they are at risk of image burn-in/retention unless properly used.

When comparing QLED vs OLED displays, both technologies have their advantages and disadvantages.

In this article, we’ll go over everything you need to know about QLED and OLED displays (both monitors and TVs) so that you can make an informed decision about purchasing your next screen.

What Is QLED?

QLED technology introduces a film layer of quantum dots between a display’s LED backlight and its panel which minimizes color crosstalk and light loss in order to increase that display’s color gamut and brightness.

These quantum dot nanoparticles can be applied to any LED-backlit panel type: IPS, TN, and VA; however, they are mostly utilized in Samsung’s VA-panel desktop monitors and TVs.

There’s one TN panel monitor with quantum dots, the Samsung U28H750, but the enhanced film of this display isn’t enough to make its picture better than that of equally-priced IPS and VA alternatives; it just provides better colors relative to other TN panel displays.

Nano IPS

What Is Oled

LG is the main manufacturer of IPS panels and they use their own technology called ‘Nano IPS‘ to enhance the LED backlights of their displays.

This technology works by applying nanoparticles directly to the backlight of an IPS panel display; these nanoparticles absorb excessive light wavelengths which allows for wider color gamut (98% DCI-P3/135% sRGB vs 95% DCI-P3/125% sRGB of QLED) in comparison to QLED.

However, VA panels still offer a higher static contrast ratio than IPS displays which results in deeper blacks (image above). This is why two main choices when it comes to high-end TVs consist of Samsung’s VA QLED and LG’s OLED TVs.

LG’s Nano IPS technology is more represented in desktop monitors, particularly in gaming displays such as the LG 34GK950F.

What Is OLED?

What Is Qled

Unlike QLED, OLED (Organic Light Emitting Diode) is a display technology of its own. It doesn’t use a backlight but produces its own light, meaning that it can achieve basically infinite contrast ratio and instantaneous response time (pixel transition) speed.

OLED also offers more accurate color reproduction and wider viewing angles which ensure there are no major alterations in color, contrast, or brightness when looking at the screen at skewed angles.

The main flaws of OLED displays include the risk of image retention/burn-in and lower peak brightness in comparison to LED displays.

Newer OLED TVs have numerous features to prevent burn-in and image retention though, you can learn more about it here.


In the end, if you’re on the fence between QLED and OLED TVs, here’s what you should know:

QLED TVs have a higher peak brightness which makes for eye-catching details in highlights of the image, but OLEDs have a higher contrast ratio that ensures deeper blacks and an overall better relation between the darkest and the brightest colors.

OLED TVs also offer a faster response time speed, more accurate colors, and wider viewing angles. However, you will have to be more careful with the TV due to the image burn-in risk, although newer models have many automatic features that will help.

As far as OLED monitors are concerned, they are still in the adaptation phase, more or less. Check out the latest development concerning OLED monitors.
