    Abstract: A barrier film on an organic electronic device. The barrier film comprises an inorganic polymeric silicon composition having Si—O—Si bonds which exhibit an asymmetric stretching Si-0 vibration frequency (AS1) ranging between 1200 cm−1 and 1000 cm−1, Si—O—H vibration frequency ranging between 950 cm−1 and 810 cm−1 and an —O—H ranging between 3400 cm−1 and 3700 cm−1 in which the ratio of peak areas for Si—O—H and —O—H vibration frequencies compared to the peak area of the Si—O—Si vibration frequency is less than 0.15. The barrier film exhibits a water vapor transmission rate between 1×10−2 g/m−2 day and 1×10−8 g/m−2 day.

    Abstract: Embodiments of the present invention provide electronic devices such as OLEDs that have enhanced mechanical integrity and prolonged shelf, by minimizing the spread of a delamination region using topographical non-uniformities introduced in the device structure. For example, a device may be made deliberately non-planar by introducing multiple energy barriers which can prevent or minimize the propagation of a delamination, because the delamination will have to cross the energy barriers in order to spread to a larger area.

    Abstract: A novel thin film encapsulated OLED panel architecture and a method for making the panels with improved shelf life is disclosed. The OLED panel consists 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 within its own hermetically sealed structure, achieved by making the structure on a barrier coated substrate and using a first barrier material as the grid and a second barrier for encapsulating the entire OLED pixel. The first barrier material provides the edge seal while the second barrier disposed over the pixel provides protection from top down moisture diffusion. By isolating and hermetically sealing individual pixels; any damage such as moisture and oxygen ingress due to defects or particles, delamination, cracking etc. can be effectively contained within the pixel thereby protecting other pixels in the panel.
