Collaborative innovation, industry university research collaboration to forge the technological highland of "Chinese screen"

As a leading Chinese enterprise in the AMOLED field, Vishino has always been driven by technological innovation and has joined forces with Tsinghua University and domestic material manufacturers to launch technological breakthroughs in the field of OLED material devices. After years of research and development, the company has successfully overcome key technological bottlenecks and released the fourth generation pTSF material device system. This system has been comprehensively upgraded from three dimensions: luminous efficiency, color gamut coverage, and device lifespan. It not only achieves purer color presentation, lower energy consumption, but also extends screen lifespan. It has officially been put into mass production and commercial use, adding core chips to the competition of "Chinese screens" in the global market.

Technological breakthrough, redefining AMOLED performance benchmark

In the development process of OLED technology, how to simultaneously achieve high efficiency, long lifespan, and high color purity of OLED has always been an important research issue. Compared to traditional OLED devices, the fourth generation pTSF device technology introduces multiple energy transfer modes, ultimately emitting light from a fluorescent emitter, achieving 100% internal quantum efficiency utilization. Moreover, the exciton lifetime of devices using pTSF technology has achieved a leap from microseconds to nanoseconds, suppressing exciton annihilation and quenching processes within the device, thereby achieving higher efficiency and longer lifetime, as well as higher color purity.

As the "barometer" of the global display industry, the SID exhibition in 2025 saw Vishino launch high-efficiency pTSF device products and wide color gamut pTSF device screens globally, which attracted widespread attention in the industry for their performance. Data shows that screens equipped with high-efficiency pTSF devices reduce power consumption by over 12% and increase lifespan by 15% compared to traditional devices. Taking a smartphone with a daily battery life of 10 hours as an example, installing this screen can increase usage time by an additional 1.2 hours, effectively solving the pain point of "fast screen power consumption" in mobile devices. The wide color gamut pTSF device body has achieved breakthroughs in color reproduction, covering DCI-P3 color gamut (>99.5%) and Adobe RGB color gamut (>99.5%), with color accuracy reaching professional design level, meeting the needs of professional scenarios such as image creation and graphic design, while reducing energy consumption by more than 6% and increasing lifespan by 20%. At present, high-efficiency pTSF devices have completed mass production and begun to be applied in various mobile electronic devices in batches.

The technological breakthrough of Weixinnuo cannot be separated from the support of the industry university research collaborative innovation system. As a pioneer in China's OLED industry, the technological roots of Weixinnuo can be traced back to the OLED project team of Tsinghua University in 1996- it was this early technological exploration that accumulated a solid research and development foundation for the company. As of now, Weixinnuo has applied for over 20000 OLED related patents, with invention patents accounting for up to 89%. The patented technology covers the entire industry chain, including materials, devices, processes, and equipment, forming a complete technical protection system. In terms of industry standards and innovative achievements, Vicino has broken the monopoly of foreign enterprises: it is a Chinese enterprise that * formulates international standards for flexible displays, has won more than 20 global "*" innovative technologies and applications, more than 50 national "first" breakthroughs, and has also won the "first prize of the the State Technological Innovation Award" of the display industry *, becoming the "synonym" of China's display technology innovation.

In November 2024, Professor Duan Lian from Tsinghua University gave a keynote speech on the improvement of OLED performance at the screen technology press conference held by Weixinnuo. The two sides had in-depth exchanges on the research and development details and application scenarios of pTSF technology, further deepening the cooperation between industry, academia and research. In fact, the breakthrough of pTSF technology is the result of long-term cooperation between the two parties. The advantages of Tsinghua University in the field of basic research complement each other's experience in industrialization, accelerating the process of technology from the laboratory to the market. Practice has proven that the advantages of pTSF technology in key indicators such as color purity, efficiency, and lifespan not only validate the effectiveness of industry university research collaborative innovation, but also provide a replicable model for the technological upgrade of "Chinese screens".

The mass production and commercialization of the fourth generation pTSF material device system by Visionor is not only an important leap forward for the company's own development, but also promotes the key transformation of "Chinese screens" from "technology *" to "product *", which is of milestone significance in the global display industry. This achievement marks that "Made in China" has completely shed its identity as a "follower" in the AMOLED field, and has become a "leader" in the industry through independent innovation. In the future, it will continue to promote technological changes in the global display industry, allowing "Chinese screens" to shine even brighter in the global market.
