BOE flexible screen volume production: whether it can solve the urgent needs of China?

On October 26th, BOE’s Chengdu Flexible AMOLED Sixth Generation Line officially entered mass production. This marks China’s first flexible AMOLED production line and the world’s second 6th-generation flexible AMOLED facility. The successful launch of this line has significantly challenged Samsung’s long-standing dominance in the small-size OLED market. It also signals that more domestic mobile phone manufacturers will soon be able to adopt OLED screens, enhancing the competitiveness of Chinese tech products globally. BOE's recent achievements are closely tied to its substantial investments and strategic positioning. After the announcement of mass production, BOE became a major focus in the capital market, drawing attention from numerous research institutions and fund companies. Investors are particularly interested in whether BOE can sustainably produce high-quality flexible AMOLED panels at scale. If successful, this would represent a historic milestone for China’s display industry, marking a significant leap forward in technological self-reliance. The journey of BOE has not been easy. Starting from the Beijing Electronic Tube Factory, the company went through several transformations, including leadership changes, restructuring, and large-scale employee layoffs. When it rebranded as BOE in the late 1990s, few could have predicted its future success. Today, it stands as a leading player in China’s panel industry, challenging even Samsung’s long-held dominance in flexible AMOLED technology. One key factor behind BOE’s growth is its aggressive investment strategy. Since its first 5th-generation line in 2005, BOE has expanded to 12 LCD production lines, with a total investment of over 359.2 billion yuan. In the new wave of technology, BOE launched two 10.5-generation lines in 2017 and invested heavily in two 6th-generation flexible OLED lines. These projects were funded through a combination of company capital, bank loans, and local government support, reflecting the strong backing from both private and public sectors. In addition to production capacity, R&D investment has played a crucial role in BOE’s success. In the first half of this year, BOE spent 3.17 billion yuan on R&D, accounting for 7.1% of total revenue—surpassing Apple’s 4.6% in 2016 and approaching Samsung’s 7.7%. This level of investment underscores the importance of innovation in maintaining competitive edge in the global display market. China is now emerging as a major player in the OLED industry, surpassing South Korea in production capacity outside of the country. BOE’s Chengdu plant, which achieved mass production ahead of schedule, is just one example of this trend. Other companies, such as Huaxing Optoelectronics, HuiGuang Opto, Shentianma, and Visoxonuo, are also building their own OLED production lines across China. By 2020, China is expected to account for six out of twelve new small- and medium-sized OLED lines worldwide. Despite these achievements, challenges remain. While BOE has made significant progress, it still lags behind Samsung in terms of production maturity and yield rates. The OLED industry relies heavily on specialized equipment, such as Japan’s Canon Tokki evaporation machines, which are critical but limited in supply. Additionally, the upstream materials and talent shortages continue to pose obstacles for China’s OLED industry. To truly compete with Korean manufacturers, Chinese panel makers need to strengthen their industrial chains by investing in equipment, materials, and joint R&D. Only through collaboration and technological advancement can China achieve sustainable growth in the OLED sector. In summary, BOE’s breakthrough in flexible AMOLED production represents a turning point for China’s display industry. While there is still a long way to go, the momentum is clear. With continued investment and innovation, China is well-positioned to challenge global leaders and reshape the future of display technology.

VFD Grid

Vacuum fluorescent display, referred to as VFD, is a low-energy electroluminescent display devices, the working principle and CRT similar. It has the incomparable advantage of liquid crystal display (LCD) in applications where there is a large variation in ambient brightness and no strict requirement for low power consumption, and is now widely used in audio-visual equipment, home electronics, automotive instruments, office equipment and instrumentation.

The structure of a VFD board is a typical vacuum triode structure, consisting of a cathode, a grid and an anode. In between the cathode and the anode there's a thin mesh of metal called the Grid that can be switched on or off, controlling the flow of electrons from the cathode to the anode. This VFD grid mesh is made of a thin metal plate with a thickness of 30 to 50μm, which is lithographed and made into a highly transparent fine lattice or tortoise-shaped metal mesh. When a positive voltage is applied to the grid, electrons emitted from the filament are accelerated and diffused toward the anode. When a negative voltage is applied to the grid, electron flow to the anode is cut off.

We custom VFD Grid with drawings provided by customers. The raw material we use for etched VFD Grid is SUS430 stainless steel. We are equipped with professional metal etching equipment and exposure development equipment. Our etched manufacturing capacity can achieve 0.05mm.
