On December 7th, Visionox announced at the Tsinghua University pTSF Technology Forum that its fourth-generation pTSF (phosphorescence-assisted thermally activated sensitized fluorescence) technology, jointly developed with Tsinghua University, has achieved mass production and commercialization, and is being used in high-end flagship products of its brand. This signifies that the long-standing dominance of foreign companies in the organic light-emitting materials industry is now a thing of the past. Professor Duan Lian of Tsinghua University, the inventor of pTSF technology, stated, "The breakthrough in pTSF technology has garnered widespread attention in the industry and will help China's OLED industry achieve a leapfrog development."
As AMOLED technology rapidly penetrates into medium-to-large-sized applications such as laptops and automotive displays, higher demands are being placed on screen energy efficiency, lifespan, and color performance. Organic light-emitting materials are the core key to driving visual upgrades. In the field of OLED materials, achieving high efficiency, long lifespan, and high color purity simultaneously has long been the "impossible triangle" that has plagued the industry.
Previously, first-generation fluorescent materials were low in cost and high in color purity, but had low luminous efficiency; second-generation phosphorescent materials had high luminous efficiency, but relied on expensive metals and had insufficient color purity; third-generation luminescent materials were highly efficient and did not require heavy metals, but were inferior in terms of stability and color purity.
Today, Visionox and Tsinghua University have jointly developed the fourth-generation pTSF technology, which has chosen a new path to solve the problem of OLED efficiency decline at high brightness and significantly extend device life. It combines the high color purity and high stability of fluorescence with the high efficiency of phosphorescence, and greatly reduces the amount of expensive metals used. It is regarded by the industry as the "optimal solution" for comprehensive performance that "has the best of both worlds".
Data shows that screens equipped with high-efficiency pTSF devices reduce power consumption by over 12% and increase lifespan by 15%. Wide color gamut pTSF devices can expand the color gamut from the traditional DCI-P3 standard to the broader Adobe and BT.2020 standards, achieving professional design-grade color accuracy, while simultaneously reducing power consumption by over 6% and increasing lifespan by 20%. This means that consumers will have screens with longer battery life, more accurate colors, and greater durability.
It is also worth noting that with the mass production and commercialization of fourth-generation pTSF, China has achieved a leap from long-term follower to independent leader in the field of key OLED materials, ending the long-standing dominance of foreign companies in organic light-emitting materials. Through the innovative cooperation between Visionox and Tsinghua University in industry-university-research collaboration, Chinese companies have mastered complete independent intellectual property rights from principles and materials to devices and processes, building a comprehensive and multi-dimensional patent barrier.
For the display industry chain, the industrialization of pTSF technology has also effectively driven the collaborative research and development and verification of upstream industries such as domestic evaporation equipment and organic materials. It represents an overall upgrade of the local display supply chain and enhances the resilience and security of my country's new display industry chain.
Meanwhile, thanks to its breakthrough performance in luminous efficiency, lifespan, and color purity, pTSF technology provides technical support for OLED to enter medium and large-sized applications such as automotive displays and IT displays, which have higher requirements for brightness and lifespan. This expands the industry's growth space and helps "Chinese screens" gain more say in the global high-end display market. |
