Invar Foil

At present, the main viewpoint of a matter of OLED product is vacuum deposition process, the use of precision metal mask (Fine Metal Mask; FMM) evaporation technology, in the dry process using the mask to make the RGB color molecules attached to the narrow pattern. When applied to large-size panels, large-size mask in the evaporation process which is easy to produce deformation and over cut of materials and other defect, to maintain a flat surface is difficult technology. The use of Invar material (for a nickel-iron alloy), its unique low coefficient of thermal expansion (CTE)) and high modulus and minimal and ultra-flatness and other characteristics to produce FMM, FMM can effectively solve the large panel due to processing heat generated , Resulting in metal mask bending and hole alignment and other issues.
