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.

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?
