OLED VS. QLED: What’s the Difference?

If you’re in the market for a new high end TV, then chances are that you’ve come across these terms: OLED and QLED.

While these two TV dsiplay technologies sound similar, the results they offer in terms of visuals is distinct. Both are at the top of the pile when it comes to excellence in display and neither is a bad choice. As you dive deeper into the waters of top-tier TV technology you’ll start noticing that it’s not really about what’s the best anymore; it’s about what’s the best for you.

OLED

Organic Light Emitting Diode Display, or OLED for short depends on individual pixels emitting light based on electric signals to each and every one of them. As opposed to LCD technology, where a back-light shines on all the available pixels at once.
This means that in OLED, a pixel can be shut off completely to display the actual screen’s color: Black. This leads to the effect you read about in marketing material called “True Black” – truly OLED’s best features.
Following the same logic of each pixel being completely independent, OLED display allows pixels to have different levels of brightness that will provide better colot contrast when working harmoniously.

QLED

Quantum Dot Light Emitting Diode Display, or QLED for short relies on tiny dots known as Quantum Dots that emit colors by forming a layer of in front of a back-light.
This technology is the evolution of LED Display where it follows the same principles of a back-light shining on an LCD panel, the only difference is the Quantum Dots. These Quantum Dots are each assigned a different color based on their size which dramatically improves richness and depth of display.

OLED VS. QLED

Now that we have a basic idea on how the mechanics of OLED and QLED TV’s work, let’s pit them against each other to highlight the differences in performances:

Black Levels


The level of Black a screen can achieve is important. The deeper and truer the Black colors are, the more realistic the display will be. While some QLED TV’s with excellent local dimming features come really close to the level of black that you’ll see on an OLED screen, a bit of light is always bound to seep through the back light which can give a light grey-ish tinge to the black. With OLED pixels having the capability to completely shut off, they are able to display black colors that are as deep and true as you’ll ever see on a TV screen.

Brightness and Contrast


If you’re going to be watching TV in bright sun-lit rooms, the higher the brightness the better. High end QLED TV’s tend to be a bit brighter. While OLED Display doesn’t quite reach those same levels of brightness, it makes up for it by having sharper color contrast which contributes to further clarity in brightly lit rooms.

To sum up, OLED and QLED TV’S are both at the forefront of visual display technology. Choosing between one or the other would depend on your preferences and the viewing environment. If all other TV specs and features are to your liking, then you definitely can’t go wrong with either choice.
