What is

Ever wonder what a QLED TV is
and how it works?
Let us break it down for you.

What’s a QLED TV and a
Quantum dot?

A QLED TV is a Quantum dot-based TV, and that Quantum dot material is what makes QLED TVs different from conventional ones.

So, what is a Quantum dot?

Quantum dots are ultra-fine semiconductor materials of nanoscale size. These dots produce different colors of light depending on the particle size—the larger the size the more red the color, and the smaller the size the more blue the color. They are able to emit precise colored light because particle sizes adjust at quantum-level velocities, resulting in accurate and efficient light emissions. The greater efficiency in luminance brings about tremendous changes in overall picture quality.

What's special
about QLED TVs?

QLED TVs take advantage of the many unique characteristics that Quantum dots offer such as "high luminance". Luminance refers to how bright a screen looks and that brightness is an important factor affecting other elements of image quality. First, contrast ratio is naturally improved when brightness is higher. When bright and dark representation of videos and images can be widely expressed, it's known as HDR (high dynamic range). This HDR, which is an essential component of picture quality, is enhanced further providing crisp and rich images.

Now, let's have a look at how all this affects color.

The effect of brightness on overall color quality is simple. For example in the red color spectrum there is a range of bright and dark reds, but QLED TVs express this range of colors better. This unique QLED technology, along with other black implementation technologies such as Direct Full Array, provides a completely different picture quality and a more realistic viewing experience compared to non-QLED TVs.

What's the difference?

It would be great if all recorded content were filmed in 4K, but there's still a lot of lower resolution content out there in comparison to 4K content. However, thankfully this is not a concern because of upscaling.

So what is 4K upscaling and what can it do for you?

When you watch lower-quality FHD content on a 4K TV, upscaling is the technology that increases its resolution, converts, and optimizes it to fit the display panel of a 4K TV. In other words, it doesn't just stretch the image — it upgrades it for the 4K display. Upscaling automatically analyzes resolution to reduce noise, improve details and provide optimum contrast and color so that you can view this content in 4K-like quality. And since every brand does upscaling differently, be sure to choose the one that does it the best.

Since TVs are not frequently replaced, you should consider carefully whether there are any factors that might lead to regret after purchase. As mentioned above, OLED TVs cannot avoid Burn-in due to the nature of their self-illuminated organic displays. Burn-in is a permanent defect in the panel where a residual screen image appears permanently on screen. If you think about frequently displayed images such as broadcaster logos, they are in the same fixed area for a certain period of time. Repeatedly displaying the same logo in the same place is enough to result in Burn-in. QLED TVs have the advantage in that you can watch your content for long periods of time without having to worry about Burn-in—allowing for an overall longer TV lifespan.

Knowing all this now, which do you think is the better option for you to invest in?
