Assisting in Publishing Two Nature Papers! LinkZill's Optoelectronics Business Hits New Highs in the Year's First Half!

At the same time, LinkZill has been growing alongside everyone. As summer arrives, we have both harvests and new seeds. This year, our optoelectronics business has welcomed a series of good news in the first half of the year, and we are excited to share it with you.

Recently, two research achievements from the team of Researcher Xingliang Dai, under the guidance of Academician Zhizhen Ye at Zhejiang University, were published in Nature Electronics and Nature Nanotechnology. LinkZill's display chips and driving systems assisted the team in validating the display performance of perovskite light-emitting diode (PeLED) displays.

In the paper titled "Microsecond-response perovskite light-emitting diodes for active-matrix displays" published in Nature Electronics, Researcher Xingliang Dai's team developed a single-particle passivation strategy that creates defect-free thin films with discrete nanostructures on the surface of perovskite nanocrystals, thereby suppressing ion migration. This solves the issue of excessively long electroluminescence rise times in perovskite light-emitting diodes (PeLEDs) caused by ion migration in active-matrix displays.

By integrating the passivated PeLEDs with custom-designed TFT backplanes from LinkZill and pairing them with display array driving systems, the team constructed active-matrix perovskite light-emitting diodes that demonstrated excellent optoelectronic performance. This strategy can also be universally applied to perovskite nanocrystal films of different colours, further enhancing the application prospects of perovskites in high-refresh-rate displays.

Dr. Linrun Feng, Dr. Yihang Yang, and Dr. Zhe Liu from LinkZill are co-authors of this paper. This also marks the first time LinkZill's IP—XiaoZhi, has appeared on the stage of 《Nature》, serving as the "spokesperson" for perovskite displays.

In the paper titled "Nanosurface-reconstructed perovskite for highly efficient and stable active-matrix light-emitting diode display" published in Nature Nanotechnology, the team developed an active-matrix display technology using perovskite quantum dots. By combining dioctyl phosphinic acid (DSPA)-mediated synthesis with hydroiodic acid (HI) etching, they achieved surface reconstruction of perovskite quantum dots, suppressing surface defect formation and significantly improving the phase stability and optoelectronic performance of perovskite quantum dots, advancing their application in optoelectronic devices.

They further integrated these surface-reconstructed perovskite quantum dots with TFT circuits specifically designed by LinkZill, paired with display array driving systems, to construct active-matrix PeLED displays. The results showed that the device exhibited uniform luminescence characteristics and set new records for the efficiency and lifespan of pure red LEDs for displays. This research also demonstrates the potential of integrating PeLEDs with TFT circuits to build novel displays.

In addition to display chips and driving systems, we have also developed sensing chips and reading systems that enable real-time detection of signals such as light and pressure, helping research teams validate the sensing performance of materials or devices. In the first half of the year, relevant research was published in   Science sub-journals, Advanced Materials、Advanced Functional Materials and other international journals.

With LinkZill's continued in-depth exploration of new sensing, display, and other fields, as well as the ongoing support of our partners, we are actively improving our product matrix and enhancing overall product performance, leading to rapid growth in our optoelectronics business.

Record High Performance in Sensing and Display Products: The transaction volume of sensing chips and reading systems in the first half of the year has already surpassed that of the entire previous year.

Global Influence Continues to Grow: Overseas business sales accounted for 21% of total revenue, a year-on-year increase of 60%. Currently, overseas customers are spread across regions including the Middle East, Europe, North America, Oceania, and Southeast Asia.

In the future, LinkZill will continue to accelerate the construction of R&D capabilities and expand our presence in overseas markets. We look forward to collaborating with more research enterprises, universities, and research institutions, and further exploring the potential of TFT semiconductors in interdisciplinary fields such as life sciences. We aim to bring innovative technologies and products to the global market and to promote the common progress and development of the international academic and industrial communities.
