Abstract
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 facing surfaces of the transparent glass layers. A coating on a transparent glass layer may be formed from a thin-film interference filter having a stack of dielectric layers. The coating may include an ink layer on the thin-film interference filter.
