The present invention discloses a novel thin film encapsulated OLED panel architecture and a method of fabricating such panels having improved pot life. The OLED panel is composed of a plurality of OLED pixels; each OLED pixel is individually hermetically sealed and isolated from its neighboring pixels. The organic stack of the OLED pixel is contained in its own hermetic sealing structure by fabricating the structure on the barrier coated substrate and using the first barrier material as a grid and using a second barrier to encapsulate the Obtained for the entire OLED pixel. The first barrier material provides an edge seal, and the second barrier disposed above the pixel provides protection against moisture diffusion from top to bottom. By isolating and hermetically sealing individual pixels, any damage due to defects or particles, delamination, cracking, etc., such as moisture and oxygen ingress, can be effectively confined within the pixel, thereby protecting the panel. Other pixels. |
