OLED vs. QD-OLED
Comparing 2 standards across 8 specifications. 6 key differences identified.
OLED (Organic Light-Emitting Diode) panels are self-emissive -- each pixel produces its own light and switches fully off for true black -- eliminating the backlight every LCD type requires. Response times run near-instantaneous, but organic material degradation makes burn-in a real, documented long-term risk.
QD-OLED combines a blue OLED light source with a quantum-dot color-conversion layer, an approach Samsung Display commercialized in 2022 -- as distinct from LG's older WOLED, which uses a white OLED source filtered through color filters. Reviewers report wider color volume as the main practical benefit.
