Seoul University, with a team lead by Professor Kim Jang-joo has developed an OLED simulation programme with CoCoLink (a company related to the university and which specialises in supercomputing) to allow the development of OLED materials and structures. The program, called Luxol OLED, is claimed to have allowed the development of the world’s most efficienct OLED (with 45% efficiency) in just two weeks. Analysing a new material could take just four minutes.
“By simulating perfectly the birefringence characteristics of the materials that make up the device, the simulator is the only one in the world that calculates error to within 1% of the real world,” said Kokolink. “We have opened up the possibility of dramatic market expansion by providing high-efficiency and low-cost technology to the OLED industry”.
The new system has exploited supercomputer technology to accelerate the calculations by a factor of 1200.
Analyst Comment
According to our understanding, Professor Kim Jang-joo has a theory that the luminous efficiency of OLED can be improved by controlling the emission dipole orientation of the light emitting material in OLED light emitting devices.
