It is reported that huancaixing Technology (Ningbo) Co., Ltd., located in Haishu Gaoqiao, Ningbo, has entered the commissioning stage of its first and only metal mask (FMM) production line in China. Its output will directly break the market monopoly of foreign companies and realize the localization and substitution of the material.

At present, the construction of huancaixing phase I is basically completed. After the first production line with an investment of nearly 100 million yuan is completed, the annual output can reach 300 million yuan. The company is divided into three phases. The second and third phases of the project will expand the production of 10 FMM production lines, with a total investment of 1.2 billion yuan, and the annual output value after full production can reach 3.5 billion yuan. The FMM produced will account for 40% of the market share.

For the familiar OLED self luminous TV, the OLED self luminous technology is usually divided into two processes: Inkjet OLED and evaporation OLED. Considering the factors of market, cost, technology and equipment, evaporation OLED is still the main technology to deal with OLED self luminous display. In this process, evaporation is a crucial link, It is particularly important to have FMM key materials.

In recent years, China’s OLED industry has developed rapidly, with an investment of more than 500 billion yuan. OLED display technology is widely used in mobile phones, personal digital assistants (PDAs), laptops, car mounted displays and televisions. Wu Bin, deputy general manager of huancaixing technology, said that FMM is the key core material of OLED semiconductor display. The market scale is RMB 6 billion in 2019 and is expected to reach RMB 10 billion in 2022. However, since FMM is still monopolized by foreign enterprises, it has become a “neck” material restricting the development of OLED display industry in China.

FMM is a metal sheet slightly wider than the panel of ordinary smart phones and thinner than paper. Millions of holes need to be etched by semiconductor process equipment in the area corresponding to the size of mobile phone display screen. The three primary colors of red, yellow and blue need to be intensively, regularly and evenly evaporated on the substrate through three sets of different fmms, so the quality of this mask directly determines the display quality.

Wu Bin said that the holes on the FMM are not only small, well arranged in position, but also irregular in shape, making production very difficult. Even with the most sophisticated semiconductor process equipment, without long-term, tens of thousands and hundreds of millions of experiments and parameter accumulation, a qualified FMM can not be produced. “We are committed to breaking the monopoly of foreign core technologies, filling the domestic gap and realizing localization and substitution,” he said

Huancaixing Technology (Ningbo) Co., Ltd., established on March 21, 2019, is an overall scheme supplier of high-precision metal mask. The company is mainly engaged in the production, sales, incoming processing, technical services and other businesses of new flat panel display mask and components. In April 2020, the company’s metal mask project was successfully applied for the 2020 electronic information industry technological transformation project by the national development and Reform Commission and the Ministry of industry and information technology, and was first recommended by the Ministry of industry and information technology to be included in the supply and demand docking platform of the industrial chain of key industries.
