JDI adopts vertical evaporation method to mass produce OLED, Korea APS supply Mask stretching machine, Japan Maxell for FMM 2019-11-16 20:44 Source: Thelec
CINNO Research Industry News, South Korea's upstream manufacturers have also helped the commercialization of JDI's next-generation OLED evaporation technology.
In the recent 2Q 2019 (accounting benchmark, July-September 2019) performance announcement, JDI announced the first mass production of OLEDs, saying that “as the world's first vertical evaporation method, this month will begin mass production. ” According to the 15th news, JDI will use the Korean KPS Masz stretcher and PIMS Open Mask (OMM). 6th generation (1500mm x 1850mm) Half Cut evaporation method.
According to JDI, “vertical-type evaporation equipment reduces the area occupied by equipment by 30% compared to current horizontal-type evaporation equipment. ” Other advantages are not explained. JDI's OLED production line in Mobara, Chiba Prefecture, Japan, has a monthly capacity of 2,000 sheets of 6-generation substrate. The company plans to produce LTPO OLED panels for Apple Watches. JDI claims that the LTPO technology is Advanced-LTPS.
I have been working on evaporation equipment for many years. People in the Korean industry said that "vertical evaporation has long been judged as a technology that cannot be mass-produced", and said that "American equipment manufacturer Applied Materials will be almost free of charge two years ago." The evaporation equipment was transferred to JDI. "
The Mask stretching equipment for Applied Materials' vertical-type evaporation equipment is supplied by APS Korea. In the field of Mask stretching equipment, Korean equipment manufacturers such as APS, Hims and Hansong Neotek are basically monopolizing the market. Hims, which previously only supplied Mask stretching equipment to Samsung, officially entered the Chinese market last year. In the third quarter of this year, the cumulative sales were nearly doubled last year, reaching 65.7 billion won (about 390 million yuan). In the same period, sales of Hansong Neotek and KPS were 15.8 billion won (about 94.94 million won) and 12.7 billion won (about 76.31 million won).
The Open Mask market is also dominated by three Korean manufacturers. Among them, Samsung's supplier Sewoo Incorporation had the highest sales, with sales of 79.1 billion won (about 480 million yuan) last year. The sales of Poongwon, which supplied Open Mask to LG, were 41.9 billion won (about 250 million yuan). PIMS related sources said that "the sales last year reached about 12 billion won (about 72.11 million won). ", "This year's sales are expected to increase to 36 billion won. ", and said that "based on FMM engineering-assisted Mask patents, Growing up quickly. "
As the first place where the display industry has emerged in Japan, most of the traditional display devices and materials are still in a monopoly position. The display exposure device is also supplied by Canon and Nikon. In terms of small and medium-sized OLED evaporation equipment, Japan's Canon Tokki and the rest of the competition have opened a big gap. Fine Mask for RGB pixel evaporation is mostly DNP, and Metal Invar, which manufactures Fine•Open Mask, is supplied by Hitachi Metal.
JDI does not use the wet mask (Wet Etch) DNP Fine Mask, but uses Japan's Maxell's electroforming alloy Fine Mask for mass production |
