Mini-LED vs. QD-OLED
Comparing 2 standards across 8 specifications. 8 key differences identified.
Mini-LED is a backlight technology, not a panel type -- it uses thousands of LEDs roughly 0.1-0.2mm in size (versus 0.5-1mm for traditional LED backlights) arranged into hundreds or thousands of local-dimming zones behind an LCD panel of any type, improving contrast and reducing blooming. TCL commercialized it in TVs starting in 2019.
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.
