The invention relates to an organic light-emitting device and a preparation method thereof. Also disclosed are thin film encapsulated OLED panel architectures, and methods of manufacturing such panels with 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 neighbors. The organic stack of OLED pixels is contained within its own hermetically sealed structure by fabricating the structure on a barrier coated substrate and using a first barrier material for the gate and a second barrier for encapsulating the entire OLED pixels are realized. The first barrier material provides edge sealing, while a second barrier disposed over the pixel provides defense 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 rest of the panel. pixels. |
