FMM

According to a report from Korea, following several years if R&D, Poongwon Precision has finally achieved high enough FMM quality and production yields to receive an approval from Samsung Display. 

The company is now gearing up to start mass producing 6-Gen FMM sheets in Q3 2024, and expects to receive the first orders from Samsung Display in September. The company is also in talks with BOE and CSoT for the supply of FMM (although it seems that it will focus on SDC until at least 2027). 

The Zapp Group, which will celebrate its 325th anniversary in 2026 and has launched a major new investment project with the construction of a 12,000 m² production hall for precision foil at its Unna site, in Germany.

The company has come a long way in the past few centuries. Having started in the Leppe Valley of Germany as a small forging shop, Zapp is now a leading metals supplier and one of only a few suppliers in the world that can produce ultra-thin foil from stainless steel, cobalt nickel or titanium alloys. This major investment will further expand its dimensional spectrum down to thicknesses of up to 0.015 mm and widths of up to 650 mm.

Dai Nippon Printing (DNP) announced that it has started mass producing fine metal masks (FMM) at its new production line at Kurosaki Plant, in Fukuoka, Japan. DNP invested $140 million to expand the production line.

The new production line is producing masks suitable for 8-Gen substrates. As the OLED industry is moving to expand its IT AMOLED display production for laptops, monitors and tablets, companies are building larger (8.7-Gen mostly) production lines that require these larger masks. While the company is already producing at the new fab, it will also announced that it may gradually expand production further at the new line, depending on market demand.

In 2022, Japan Display (JDI) announced that it has developed a "historic breakthrough in display technology" - a new OLED deposition process which they refer to as eLEAP, that is said to be cost effective and can be used to create freeform OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM).

JDI is planning to establish a 8.7-Gen eLEAP fab in China, and it is also building a smaller-scale 6-Gen eLEAP production line in Mobara, Japan. The company announced that the 6-Gen Mobara fab is advancing ahead of schedule, and production of eLEAP panels will begin before the end of 2024. JDI developed 14" laptop panels that are three times brighter than other OLEDs (at 1,600 nits), and is also targeting smartwatches, smartphones and automotive displays. JDI is also looking into adopting a tandem structure, to increase brightness even further to 3,000 nits.

Japan Display announced an agreement with China-based LCD maker HKC Corp to mass produce panels by 2025 in China, based on JDI's technology, but the plan was later cancelled, and JDI said it will establish its own factory in China. The company was negotiating with the Wuhu Economic and Technological Development Zone (in Anhui Province), aiming to establish two eLEAP AMOLED production lines by 2025. JDI hoped to sign the formal agreement before the end of 2023.

JDI now announced that it is scaling back its plans. Originally JDI aimed to establish two production lines: one 6-Gen (with a capacity of 10,000 monthly substrates) and one 8.7-Gen (30,000 monthly substrates). Now JDI decided to reduce its plans, to a single 8.7-Gen fab. In addition, it estimates it will sign the final contract in March 2024. The 8.7-Gen line will start mass production in December 2026.

TCL CSoT says that it will start producing OLED displays using an inkjet printing process in the second half of 2024. This is excellent news and good to know CSoT is still on track for initial production in 2024. The company says it will first target the IT and medical sector. 

The company says that the cost of producing OLEDs using its inkjet printed panels will be lower compared to the currently-used FMM based method, and its OLEDs will offer superior performance (in lifetime, mostly) as its process enables higher aperture.

The company now says that it is progressing with its negotiations with the Wuhu Economic and Technological Development Zone (in Anhui Province), and the hope is to reach a final agreement will be reached by the end of the year. Interestingly, JDI also says that it is considering building an eLEAP AMOLED fab in India, but we do not have more details.

A report from Korea's The Elec publication says that Samsung Display is highly interested in next-generation OLED deposition technologies, that are not based on a metal mask (FMM). Several companies are developing and commercialization such technologies. As these may enable higher-performance OLED production, Samsung Display is interested.

A few months ago we reported that SDC is interested in SEL's maskless production technology, and indeed the new The Elec report states that the two companies are in talks. SEL is one of the three companies we are aware of that have advanced maskless technologies, the other two being Visionox and Japan Display. Samsung Display is mostly interested in a technology that it can exclusively license as it does not want other companies to produce OLEDs using the same technology. Both Visionox and JDI are interested in using their technologies in-house, which is a problem for SDC.

Japan Display announced an agreement with China-based LCD maker HKC Corp to mass produce panels by 2025 in China, based on JDI's technology. But now it is reported that this joint venture is canceled. The report suggests that the two companies could not agree on a license fee that HKC was to pay to JDI. There is speculation that the HKC's canceled IPO and the slowdown in China's economy are to blame.

According to reports from Korea, Samsung Display is interested in acquiring OLED IP and patents from Semiconductor Energy Laboratory (SEL). These patents detail an OLED production process that does not require the use of fine metal mask (FMM) evaporation.

The use of FMM to deposit and pattern OLED displays is seen as a major setback towards higher density OLED displays, and it also limits the aperture ratio. It is no wonder that Samsung is interested in such technology, as other display makers have developed similar technologies that offer massive performance boost over the standard FMM process.
