QD-OLED vs. WOLED
Comparing 2 standards across 8 specifications. 7 key differences identified.
Comparing:
QD-OLED
WOLED
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.
WOLED is LG Display's OLED TV technology, using white-emitting OLED subpixels combined with red, green, blue, and white color filters (WRGB) rather than individually colored OLED subpixels. LG launched the first WOLED TV, a 55-inch model, in 2013, and remains the primary manufacturer of large-panel WOLED, supplying other brands including Sony.
