What is QD OLED? And is it better than OLED TVs?
Apr 4, 2025
Samsung’s QD-OLED display entered the TV market as a challenger to LG Display’s WOLED panels, and in a short space of time it’s established itself as one of the best TVs and gaming monitors in the world.
After dismissing OLED technology for well over a decade, Samsung re-entered the market and created panels of its own to fix the issues it had with OLED – namely a lack of brightness and a reduced colour performance.
It’s arguably done that and more by merging Quantum Dot colour technology with OLED’s pixel level dimming ability, spurring LG Display’s WOLED panels to even greater levels of performance.
With this guide we explain what QD OLED is, how it works, where you can find it, and ultimately whether it’s worth getting a QD OLED display.
What are Quantum Dot TVs?
Quantum Dot displays are more advanced versions of LCD LED TVs. They make use of nano-sized particles that absorb and emit light. When light is passed through these particles, different sizes produce different wavelengths (i.e. colours).
Quantum Dots are known for their purity which means they can display colours more accurately, and their light efficiency also allows for greater brightness, which is useful for dealing with HDR content.
What’s more Quantum Dots are very stable. That means the stability of image quality is maintained over a longer period than, say, WOLED (White OLED) TVs, which degrade over time.
