"To surpass South Korea's pursuit and achieve technological independence" December 11, 2025/ Category: Display , Focus On / Author: UBIResearchNet jpn.ubiresearchnet.com China's display industry has surpassed the top spot in production volume, setting a milestone toward independence in core material technology. Tsinghua University and Visionox officially announced the successful mass production of Phosphor-assisted Thermally Activated Delayed Fluorescence Sensitized Fluorescence (pTSF) technology, a fourth-generation OLED light-emitting technology, at a technical forum co-hosted by Beijing Tsinghua University on the 7th, and unveiled the results of its application. This announcement is seen as a significant milestone, marking the successful introduction of next-generation material technology, which had previously remained in the realm of possibility in academia, into actual mass production lines and entering the commercialization stage. Phosphor-assisted Thermally Activated Delayed Fluorescence Sensitized Fluorescence (pTSF) technology is a fourth-generation technology that has solved the "impossible triangle" problem of existing OLEDs, which was difficult to achieve simultaneously with the three elements of high efficiency, long life, and high color purity. This technology operates on the principle of maximizing efficiency and life by constructing an original triple energy transfer system consisting of a TADF host, a fluorescent assisting dopant (sensitizer), and a fluorescent emitter, and capturing internal energy without loss and quickly transferring it to the emitter. In particular, this forum attracted attention by reconfirming the mass production performance data of green phosphor-assisted thermally activated delayed fluorescence sensitized fluorescent (pTSF) elements, which attracted the attention of the academic community at SID 2025, the world's largest display conference, held in May.

Product A, a low-power model, reduced power consumption by 12% and improved lifespan (LT95) by more than 15% compared to existing fluorescent OLED products. Product B, an ultra-high-definition model, also achieved a color reproduction rate of more than 99.5% for both the DCI-P3 and AdobeRGB color gamuts, demonstrating dramatic improvements in image quality. This was achieved by increasing energy transfer efficiency through the application of an exciplex host developed by the research team and optimizing the device structure, while reducing the use of expensive dopants by approximately 10%. The technology unveiled this time is expected to be installed in Honor's Magic series and Nubia's latest models. Honor and Nubia have been long-time core partners of Visionox, and have a track record of being the first to introduce Visionox's new technologies (high refresh rate, UDC, etc.) to their flagship lineups in the past, so it is highly likely that they have been given priority in supplying this 4th generation technology as well. Building on this successful mass production of green elements, Tsinghua University and Visionox have presented a roadmap for expanding the application of Phosphor-assisted Thermally Activated Delayed Fluorescence Sensitized Fluorescence (pTSF) technology to red and blue elements. The research team is currently focusing on ensuring the stability of the red MR emitter and blue auxiliary phosphor, which are considered technically challenging, and plans to achieve complete independence in material technology across the entire OLED range. The Chinese side believes that this achievement will mark an important milestone in the Chinese display industry's transformation from a follower to a technology lead er.
