IPS vs. QD-OLED
Comparing 2 standards across 8 specifications. 8 key differences identified.
IPS (In-Plane Switching) panels offer the widest viewing angles of the common LCD types -- 178°/178° is standard -- and the most consistent color, making them the default for color-critical monitors and most phone LCDs, at a contrast ratio similar to TN's.
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.
