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 colours of light depending on the particle size—the larger the size the more red the colour, and the smaller the size the more blue the colour. They are able to emit precise coloured 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?
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.
