What is OLED(Organic Light Emitting Diode)?

OLED is an abbreviation of organic light emitting diode which means the future display in that the holes and electrons injected from the positive and negative poles meet at the organic light-emitting layer and emit the lights.OLED, atomic emission element, doesn’t need backlight. So it is very slim and light.As OLED is made using the organic materials, you can bend or twist the display as if it is a scroll, and you can implement it transparently.

It is no doubt that one of the next trends in display technology is Organic Light Emitting Diodes (OLEDs). Phosphorescence OLED technology plays an important role in meeting the demand for power saving device applications. CHEMWILL is dedicated to the integration of display technologies such as LCD, AMOLED, E-paper, touch, and oxide transistors.

CHEMWILL possesses extensive production know-how of OLED materials and the pre-step chemicals.For example:

* Suzuki coupling
The Suzuki coupling is a reaction to obtain biphenyl derivatives by cross coupling. The reaction of aromatic halides with arylboronic derivatives yields the corresponding biphenyl derivatives.

* Grignard reaction
The Grignard reaction is an important method in organic synthesis for the preparation of carbon-carbon single bonds, mainly by combining nucleophilic alkyl- or arylmagnesium halides with electrophilic compounds like aldehydes, ketones or esters to yield alcohols. It is also important for the reaction with boron derivatives which are subsequently used as reactant in the Suzuki coupling.
