(Quantum dot LED) A display technology that uses phosphorescent crystals to improve the LED backlight on an LCD TV. In 2017, Samsung introduced its QLED line of 4K TVs, which are LCD-based TVs augmented with quantum dot nanocrystals.

Dual LED. Innovative backlighting technology delivers bolder and more accurate contrast by optimizing the backlight color tone to match the type of content being watched.

Correct Answer: 100%. Samsung's new 55-inch QLED TV delivers 100% Color volume with Quantum Dot so that you enjoy an immersive viewing experience.

Whilst QLED TVs tend to have a higher peak brightness, a long lifespan and are well suited to brightly-lit environments. Learn more about the differences between QLED, OLED & LED in our guide.

In a nutshell, LED TVs give you good contrast and energy efficiency, QLED TVs have higher resolutions, brighter and vibrant colours, while Neo QLED is the latest landmark precision TV technology by Samsung.

'100 percent color volume' presents color that can be expressed regardless of the different levels of brightness. For example, a leaf can be perceived as different colors, from yellowish green to turquoise, depending on the brightness of the light.

Enhanced Color Spectrum Quantum dots are far more precise in arranging the colors. That helps QLED TVs have an increased color accuracy. You can see even the individual blades of grass with absolute clarity. The older LCD TVs have a shallow color profile than the QLED TVs.

LED and QLED TVs are similar to each other as they each use LCD panels with LED backlights; the only difference is that QLED TVs use a quantum dot layer that allows them to produce a wider range of colors.

The “Q” in the QLED stands for Quantum, which sounds high-tech and futuristic. While the tech is appealing to hear and flaunt, it is similar to traditional LED TVs, but with some advantages. The additional Quantum Dot filter results in more accurate colours and brightness.
