OLED (Organic Light-Emitting Diode) is a display technology where each pixel emits its own light, enabling perfect blacks, infinite contrast, and vivid colors compared to backlit LCD panels.
OLED panels turn off individual pixels to display true black, producing infinite contrast ratios that LCD cannot match. Colors appear more saturated and viewing angles stay consistent.
Downsides: OLEDs can suffer from burn-in if static images display for thousands of hours, and peak brightness is typically lower than mini-LED LCDs in HDR.
Found in flagship smartphones, premium TVs (LG, Sony), and increasingly in laptops and tablets. AMOLED and Super AMOLED are Samsung's variants of the same underlying technology.
