Organic light-emitting Diode (OLED) : Organic light-emitting Diode (OLED), also known as an electromechanical laser display, is a self-luminous display that USES a very thin Organic material coating and glass substrate that emits Light when an electric current is applied, and an OLED display has a large viewing Angle and low power consumption. OLED has the advantages of self-illumination, no backlight (it will not light up only when it is powered on, and only when the driver and wiring are correct), high contrast, thin thickness, wide Angle of view, quick reaction, flexible panel, wide temperature range, simple structure and process, etc.
