From October 12th to 14th, the 2020 International Display Technology Conference (ICDT2020) was held in Wuhan. This conference brought together display enterprise elites and academic circles to conduct exchanges on multiple topics in the field of information display, aiming to actively promote display technology The research and development of intelligent manufacturing technology. As an excellent R&D and production manufacturer of OLED and color photoresist materials, BJDC Optoelectronics Technology Group brought us the company's latest R&D progress in OLED materials and technology at this conference.
Dr. Li from the BJDC R&D Center delivered a speech titled "High-Performance Deep Blue OLEDs with EQE up to 31%", "High-Performance Deep Blue OLEDs with EQE up to 31%" (TASF) Prospective research on technology and current results. Through TASF technology, the HFDC technical team aimed at commercial blue chromaticity requirements, combined with material molecular design and development and device structure innovation, and achieved a breakthrough in performance in a deep blue bottom-emitting OLED device with an emission wavelength of 460nm, achieving up to 31% of external quantum effectiveness. On this basis, the deep blue top-emitting OLED device developed by HFDC achieves a blue coordinate CIE y<0.06 and a blue efficiency index Blue index>260 at a brightness of 1000 nit. This is the international deep blue OLED under this light color. The highest efficiency achieved, and at the same time, the program has reached the target of commercial application in the driving voltage.
Dr. Zeng from BJDC R&D Center gave a poster with the title "Developing High-Performance OLED Materials with Diverse Properties for Various DisplayMakers" "Developing High-Performance OLED Materials with Different Characteristics for Display Panel Customers", and introduced HFDC's independent knowledge in development The latest achievements in proprietary high-performance OLED functional layer materials. After long-term dedicated investment and continuous iterative development, HFDC has accumulated a large number of electron transport materials and auxiliary luminescent materials with various carrier transport characteristics and various energy levels, forming a rich material sample library, which can be used for different customers according to different products The improvement of screen body performance requires customized supporting material design and development and screening services to improve display panel performance. This kind of self-patented materials has broken through the patent monopoly of foreign manufacturers, and provided panel manufacturers with a more cost-effective and more range of selection of OLED material types, supporting Chinese panel companies to accelerate the resolution of the problem of squeezing the neck, achieve supply chain security, and promote This has contributed to the healthy development of China`s OLED display industry.
