OLED is also named Organic Electroluminescence Display. The OLED has self-luminous properties, using very thin organic coating and glass substrate, when the current passes, the organic material glows, and the OLED display screen has a large visual angle and can save electricity significantly. So this OLED screen has a lot of advantages that LCD doesn't have it.
The basic structure of OLED is a thin, transparent, semiconductor characteristic indium tin oxide (ITO), connected to the positive electrode of the electric power, plus another metal cathode. The entire structure layer includes the hole transport layer (HTL), the luminescent layer (EL) and the electron transport layer (ETL). When the power is supplied to the appropriate voltage, the positive and cathode charges will be In the luminescent layer, the light is generated by combining the red, green and blue primary colors.
OLED is characterized by its own luminescence, unlike the backlight required by TFT LCD, so it has high visibility and brightness, followed by low voltage requirements and high power saving efficiency, plus fast response, light weight, thin thickness, simple construction, low cost, etc. Be regarded as one of the most promising products of the 21st century.
OlED materials are produced from OLED intermediates through a series of reactions. Our company is one of the suppliers of OLED intermediates, mainly selling 2.7-dibromofluorene products. CAS:16344-88-8 ,Long-term stable supply, welcome overseas customers to come to consult.
