Core Viewpoint - Recent advancements in OLED technology have been achieved by overseas universities, highlighting significant improvements in data transmission rates and the development of new OLED materials. Group 1: OLED Communication Breakthrough - A collaborative team from the University of St Andrews and the University of Cambridge has set a new record for OLED communication, achieving a data transmission rate of 4 Gbps over a distance of 2 meters, which is a 25% increase from the previous record of 3.2 Gbps [2][5] - The team maintained an effective transmission rate of 2.9 Gbps over a 10-meter link, extending the previous single OLED transmission distance by 40 times [5] - The stability of OLED devices is identified as a key factor in achieving high-speed communication [5] Group 2: Development of New OLED Materials - A research team from Kaunas University of Technology in Lithuania, in collaboration with Ukrainian scientists, has developed a new type of OLED emitting material that demonstrates efficient light emission [8] - The researchers synthesized three derivatives of phenylthiazine and phenylpyridine through Buchwald-Hartwig cross-coupling reactions, showing excellent hole mobility, particularly in derivatives containing tetracene groups [8] - OLED devices based on these new materials emit blue light at a wavelength of 500 nm, achieving a brightness exceeding 1000 cd/m² and an external quantum efficiency (EQE) ranging from 2.5% to 6% [9]
