QD-OLED vs. QLED
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
QD-OLED
QLED
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.
QLED, despite its OLED-like name, is not a self-emissive technology -- it's a conventional LED-backlit LCD panel with a quantum-dot film added between the backlight and the LCD layer to produce more precise color. Samsung introduced it in 2017; it still requires a backlight and has the same blooming limitations as other backlit LCDs.
