Title: Innovations of Justin Thomas Koil Pitchai Rajapandian
Introduction
Justin Thomas Koil Pitchai Rajapandian is an accomplished inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of organic light-emitting diodes (OLEDs) through his innovative patents. His work focuses on developing advanced light-emitting materials that enhance the efficiency and performance of OLED technology.
Latest Patents
Rajapandian holds two notable patents. The first patent is for an electro-fluorescent emitter designed for ultra-violet OLEDs. This invention features a newly synthesized carbazole scaffold-based emitter, 9-butyl-2,7-(2-(4-methoxyphenyl)ethynyl)-9H-carbazole (Cz(APhOMe)). It has demonstrated a high quantum yield of approximately 78%. When doped into a host light-emitting layer of an OLED, Cz(APhOMe) emits pure UV light with a single peak wavelength in its emission spectrum. This pure UV light has numerous applications, including biological sensors, chemical sensors, and forensic investigations.
The second patent involves a novel light-emitting material that is a blue fluorescent material with a high quantum yield of around 86%. This material can be incorporated into a host light-emitting layer of an OLED to improve external quantum efficiency, power efficiency, and current efficiency. Experimental results indicate that this material emits deep blue light with CIE coordinates of (0.156, 0.055). Additionally, it can be produced through both dry and wet processes, facilitating low-cost mass production of OLEDs.
