(Organic Light-Emitting Diode)
OLED is a display technology that consists of small dots of organic polymer that emit light when charged with electricity.
Compared to LCD displays, OLED displays...
- are thinner
- are lighter weight
- have better viewing angles
- have faster refresh rates
- use less power
- are simpler and cheaper to manufacture
OLED displays used as primary phone displays are all active-matrix, sometimes referred to as AMOLED.
OLED displays can be manufactured on a base of glass or plastic (sometimes called pOLED). Plastic permits OLED displays that are more durable, curved, or even flexible, enabling foldable phones.
The earliest OLED displays were small and often single- or multi-color, but they now come in all sizes, and most are now full-color.
