Several Korean firms (including Samsung and LG) have signed a memorandum of understanding (MOU) to join hands in developing equipment to manufacture large-size AMOLED displays (i.e. OLED TV panels) . Korea wants to get a top-position in OLED displays and lighting, and the firms committed to further investments in these fields.
Under the MOU, the companies (Samsung Mobile Displays, LG Display and other companies) will co-develop and mass-produce vapor deposition equipment for AMOLED panel production. Korea wants to not only use Korean-made equipment in their own OLED plants, but also to become an exporter or such equipment (currently most of this equipment comes from Japan).
Back in May 2009, LG and Samsung have already committed to co-develop OLED manufacturing equipment.
