OLED displays can be manufactured on a base of glass or plastic (sometimes called pOLED). Plastic permits OLED displays that are more durable, and even curved.
Smaller, secondary OLED displays come in single-color, multi-color, and full-color varieties. OLED display modules used in secondary displays are sometimes of a simpler type using passive-matrix technology.
