OLED Materials

Organic light-emitting diode (OLED) is a light-emitting diode in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.

Fundamentally different from LEDs which is based on a p-n diode structure, OLED can be made transparent and extremely lightweight as well as exhibits increased versatility and flexibility. As a self-light-emission device, an OLED display can work without a backlight, resulting in a higher contrast ratio and brighter color presenting comparing to a liquid crystal display.

TADF materials: The maximum internal quantum efficiency (IQE) of OLEDs that rely on fluorescence is limited by the abundance of triplet states. Classical fluorescent OLED devices have a low maximum internal quantum efficiency of 25% for radiative decay from the triplet state (T1) to the ground state singlet (S0) is forbidden due to conservation of angular momentum. In TADF, excitons in excited triplet state gain thermal energy from their surroundings and then transit to the excited singlet state through a reverse ISC process. As a result, TADF OLED devices could achieve a maximum internal quantum efficiency up to 100%.

We are delighted to present our company as one of leading suppliers of OLED (conventional and TADF) related materials and synthesis intermediates. Furthermore, we possess cutting-edge analysis instruments capable of precisely evaluating product specifications such as UV, PL, LUMO, and HOMO. With a strong focus on quality and a consistently expanding product options, we are committed to catering to the ever-growing demand in the OLED industry.
