Introduction

Article illustration 

OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs are emissive display that do not require a backlight and so are thinner and more efficient than LCD displays (which do require a white backlight).

 

The products of OLED intermediates produced by our company is a kind of organic electroluminescent materials to make OLED display screen

 

OLED displays are not just thin and efficient - they provide the best image quality ever and they can also be made transparent, flexible, foldable and even rollable and stretchable in the future. OLED represent the future of display technology!

 

The intermediate can be used in OLED series, such as Thiophene series, Fluorene series, Boronic Acid series and so on.
