FMM(Fine Metal Mask)
FMM Fine Metal Mask
Fmm is a fine metal mask and is a production subsidiary material that is used for OLED production. Fmm has been produced only in Japan and tried to localize, but it cannot succeed due to technical barriers. Finished development of FMM technology using graphene in GrapheneLab.

  • Example of FMM Caught by Jig

  • FMM Used for OLED

Strong Point Of GrapheneLab Co., Ltd.

Currently, the FFM market has problems such as W company's base substrate separation and plating quality problems, A company's Burr removal limit and Sharp adjustment problems, and D company’s over-etching and non-etching problems.

In contrast, GrapheneLab Co., Ltd. ensures high yield through a method of conductive material (CVD graphene) based on graphene.

Currently, it occupies the exclusive market of D Company in Japan, and export sanctions are being developed during the exclusive supply to S Company.

Two companies are under development in Korea, but they have no performance so far and are negative for the following reasons.
Method Issue Possible Future Strength / Developer
Based Graphene
