| titleOfInvention | A method for reducing water and oxygen permeability of OLED devices |
| abstract | The invention provides a method for reducing the water and oxygen permeability of an OLED device, comprising the following steps: A, preparing a metal foil by a constrained sintering method; B, coating a layer of a hydrophobic polymer layer with a thickness of 5-10 μm on the metal foil, Obtain the OLED device substrate; C, the other side of the OLED device substrate obtained in step B is bonded to the OLED by glue, the OLED device is coated, and then the two ends of the metal foil substrate are continuously turned outward for at least 2 and use glue to bond the folded surfaces to obtain an OLED device with low water and oxygen transmission rates. The present invention uses the protruding part of the metal foil in combination with an organic adhesive to package and protect the periphery of the organic electroluminescent device, and the flexible metal The two ends of the substrate are continuously bent for multiple times, and at the same time, the problem of water/oxygen penetration at the bottom and the surrounding area is effectively solved, and the influence of water vapor and oxygen on the electrode materials and organic light-emitting materials is reduced, which is beneficial to slow down the aging of the device and prolong the life of the device. It meets the requirements of organic electroluminescent devices for substrates. |
