Introduction – What is QLED and Why Should You Care?
QLED, short for Quantum Dot Light Emitting Diode, is a display technology that enhances traditional LED screens with a layer of quantum dots—nanoparticles that emit vivid colors when illuminated. Known for their exceptional brightness, durability, and color volume, QLED displays have quickly become a go-to solution in televisions, monitors, and professional visual systems. In a world where visual communication and immersive experiences are more vital than ever, QLED stands out as a bridge between high-performance technology and user-centric design.

How QLED Works – The Science of Light and Nanocrystals
QLED technology leverages a backlight unit, typically LED-based, that shines through a film of quantum dots. These dots—tuned to emit specific wavelengths—convert blue light into highly saturated reds and greens, producing a wider color gamut and enhanced brightness. Unlike OLED, QLED is not self-emissive, but its structure allows it to outperform in luminance and lifespan. Key advantages include high peak brightness, minimal burn-in risk, and excellent energy efficiency when paired with local dimming backlights.
