Electronic Device Coatings With Organic Components

An electronic device may have a housing surrounding an interior in which electrical components are mounted. A display may be mounted to housing structures in the device. The housing may have a rear wall. The display cover layer and rear wall of the housing may be formed from transparent glass layers. Coatings may be formed on inwardly and/or facing surfaces of the transparent glass layers. A coating on a transparent glass layer may be formed from one or more PVD layers. A buffer layer that includes a hybrid material with an organic component may be interposed between the glass layer and the PVD layers to increase the retained bend strength of the glass layer. Alternatively or additionally, the PVD layers may form a thin-film interference filter, and some of the PVD layers may be formed from the hybrid material to increase the retained bend strength of the glass layer.
