OLED(Organic Light Emitting Diode)

OLED displays utilize organic compounds to emit light when an electric current is applied. It is thin, lightweight, and offers flexibility in display implementation, making it suitable for flexible and transparent displays, as well as for automotive displays and AR/VR applications.
