Visionox recently made a significant breakthrough in display technology, becoming the first to successfully utilize solid-state laser annealing (SLA) technology to convert amorphous silicon thin films into polycrystalline silicon thin films, achieving mass production and successful panel illumination. Mass production using SLA technology is expected to commence at Visionox's Kunshan factory by the end of February 2025. This landmark achievement marks the first successful application of SLA technology on an AMOLED mass production line, injecting strong impetus into the innovation and upgrading of the AMOLED industry and heralding a new era for display technology.

Laser annealing is a core process in AMOLED display technology, and its stability directly impacts the final product's display quality. Laser stability is the core element of the laser annealing process. For nearly two decades, the industry has widely adopted excimer laser annealing (ELA) technology, which, while driving the development of the AMOLED industry, has increasingly revealed inherent flaws. ELA technology has a narrow process window and poor stability; slight process fluctuations can lead to a decline in product display quality, significantly increasing process control difficulty and costs. To ensure product quality, ELA equipment requires frequent replacement of special gases and related spare parts to maintain process stability. This not only leads to high production costs but also severely limits equipment uptime, hindering efficient factory development.

As a leading AMOLED company in China, Visionox has always been committed to promoting industry technological upgrades and guiding the display industry toward high-quality development. Facing the bottlenecks of ELA technology, Visionox's Kunshan factory bravely took on industry responsibility, pioneering the improvement and research and development of solid-state laser technology (SLA), achieving a significant breakthrough from scratch.

This breakthrough was not achieved overnight but is the result of over a year of rigorous design and verification by Visionox and APSYSTEMS, deeply exploring the potential of SLA technology. Ultimately, SLA technology demonstrated significant advantages over ELA technology in several aspects:

Significant Quality Improvement: SLA technology boasts an energy variation coefficient of only 0.2%, significantly improving laser pulse energy stability. This effectively improves the Mura phenomenon (color difference or uneven brightness on the screen) in AMOLED screens, significantly enhancing display quality and providing consumers with a superior visual experience. ELA technology has larger energy fluctuations and struggles to maintain consistency and stability, while SLA technology's significant advantages solve long-standing industry display quality challenges. This quality improvement is reflected not only in visual effects but also in increased product yield and reduced scrap rate, further lowering production costs.

Significant Cost Reduction: A major advantage of SLA technology is its elimination of the need for special gases. This directly eliminates the high costs associated with replacing consumables and spare parts, significantly reducing operating costs. Compared to ELA technology, the cost savings in operation and maintenance for SLA technology are substantial. The procurement, storage, replacement of special gases, and related maintenance costs account for a considerable proportion of AMOLED production. This SLA breakthrough effectively controls production costs and enhances the company's competitiveness.

Significant Capacity Improvement: Aside from the laser head, SLA technology requires virtually no daily maintenance, contrasting sharply with ELA technology, which requires frequent replacement of special gases. The low maintenance characteristics of SLA technology significantly improve equipment uptime, meaning more products can be produced in the same amount of time, greatly improving production efficiency. Furthermore, SLA technology can operate at higher frequencies, with single-unit equipment capacity expected to increase significantly, further improving production efficiency and reducing the unit production cost. Higher capacity also means companies can respond more quickly to market demand and meet growing market needs.

Visionox's Kunshan factory is expected to achieve mass production of SLA technology by the end of February 2025. This marks a new stage in AMOLED production processes and lays a solid foundation for the overall upgrading and transformation of the display industry. Mass production will not only benefit Visionox itself but also drive technological advancements and industrial upgrades within the entire AMOLED industry. More companies will have the opportunity to adopt SLA technology, thereby improving product quality, reducing production costs, and enhancing market competitiveness.

Based on the successful mass production of SLA technology, Visionox will continue to lead innovation in the OLED manufacturing field, focusing on the research and development of larger-size screens, higher-performance, and better user experience AMOLED products. This technological breakthrough reflects not only Visionox's technical capabilities but also its determination and strength in promoting industrial upgrades and leading industry development. In the future, we can expect Visionox to deliver more groundbreaking results in display technology, bringing consumers more advanced and high-quality display products.

Visionox's success also provides valuable experience and reference for other AMOLED manufacturers. The application of SLA technology will drive technological innovation across the industry, promoting fair competition, ultimately benefiting the entire industry and consumers. This is not only Visionox's success but also a symbol of technological progress in China's display industry, a significant step toward the forefront of display technology. We believe that, in the future, more Chinese companies will make breakthroughs in the display technology field, contributing to global display technology development. Visionox's breakthrough deserves industry attention, and we look forward to its future development and innovation in display technology.
