OLED
Self-emissive display where every pixel makes its own light.
OLED (Organic Light-Emitting Diode) panels emit light per-pixel rather than relying on a backlight. Result: perfect blacks, infinite contrast, and pixel-level dimming that LCD physically cannot match. The tradeoff is peak brightness (~1000-3000 nits on 2026 panels vs 4000+ on top Mini-LED) and the long-term burn-in risk on static UIs. Variants in the wild: WOLED (LG), QD-OLED (Samsung Display), and AMOLED (the active-matrix flavor on phones).
