Quantum Dot (or QLED) displays use a layer of nanoparticles called Quantum Dot Enhanced Film between their panel and LED backlight which increases that display’s color gamut and brightness.
A quantum dot display features a Quantum Dot Enhanced Film (QDEF) consisting of nanoparticles between its panel and its LED backlight which improves the color gamut and luminance of the display.
These particles can be applied to any panel technology including IPS, TN, and VA, and they can increase the display’s color gamut to cover 125% of the sRGB color space or 95% of DCI-P3 which is essential for the optimal HDR (High Dynamic Range) viewing experience.
Samsung is the main producer of quantum dot enhanced displays (including both TVs and desktop monitors) that are branded as ‘QLED’.
While Samsung applies the quantum dot technology to their VA panels, LG uses the Nano IPS technology to improve the LED backlights of their IPS-panel displays. Learn more about Nano IPS.
Even though Nano IPS displays can have a wider color gamut (135% sRGB and 98% DCI-P3), Samsung’s QLED TVs are more popular as VA panels offer a significantly higher contrast ratio whereas the Nano IPS technology is more suitable for desktop monitors.
We’ve reviewed several QLED monitors. The most popular displays include:
- Samsung C24FG73 – an affordable 24″ 1080p 144Hz VA curved gaming monitor
- Samsung U28H750 – a 4K TN monitor
- ASUS ROG Swift PG27UQ – a high-end 4K 144Hz IPS gaming monitor with G-SYNC Ultimate.
