Abstract: Embodiments of a thin film protective barrier for an encapsulated electronic device is disclosed. The barrier is applied as a thin film coating onto a moisture-sensitive microelectronic device, such as an OLED. A density of the barrier is varied during fabrication, allowing the barrier to flex in applications that demand that the encapsulated electronic device be flexible, while providing a highly-resistant barrier to moisture, oxygen and other contaminants.

Abstract: A method to enhance retention times for electrochromic devices. In one embodiment, an electrochromic device described herein is formed having a multilayered electrolyte layer, rather than a single layer normally used in prior art electrochromic devices. The use of a multi-layered electrolyte layer helps minimize the deleterious effects of pinholes and other defects in the electrolyte layer and significantly improve the retention time for colored and/or bleached states in such electrochromic devices.
