OLED display is an application of OEL display technology, in the past ten years, more and more scientific research forces have been invested in the research and development of OLED technology, OLED display structure and OLED display technology is becoming more and more mature.
OLED display components:
Base layer (transparent plastic, glass, metal foil) – The base layer is used to support the entire OLED.
Anode (transparent) – The anode eliminates electrons as current flows through the device (adding electron holes).
Organic layer – The organic layer is composed of organic molecules or organic polymers.
Conductive layer – This layer is made up of organoplastic molecules that transport holes from the anode. Polyaniline can be used as a conductive polymer for OLEDs.
Emission layer – this layer consists of organoplastic molecules (unlike the conductive layer) that transport electrons from the cathode; The luminescence process takes place at this level. Polyfluorene can be used as an emitting layer polymer.
Cathode (can be transparent or opaque, depending on the type of OLED) – When current is flowing through the device, the cathode injects electrons into the circuit.
