Novel sealing technology for organic EL display and lighting by means of modified surface activated bonding method

For a sealing of organic electro luminescence displays and lightings, a room temperature bonding of polymer films without organic adhesives is required. This paper describes a new bonding technique called modified surface activated bonding (mSAB) method using nano-adhesion layer that meets the requirement. Polymer films such as PEN, PET and PI can be bonded by this method. Especially PEN and PET films are so strongly bonded that the bond interface has tolerance for bending and loci of fracture after a peeling test are located in the polymer bulk. The organic electro luminescence lighting bonded by the proposed method clears environmental tests such as high temperature and high humidity tests.
