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.
