Abstract
Various embodiments of smart devices are determined herein. A smart device can include a housing and an electronic display. The smart device can further include a cover, housed by the housing, through which the electronic display is visible. The cover can include a glass layer, wherein the glass layer is the outermost layer of the cover that is adjacent an ambient environment of the smart home device. The cover can further include an optical coating layer, deposited directly onto a surface of the glass layer, that comprises a plurality of sublayers. The optical coating layer can include alternating non-metallic oxide layers having different refractive indexes. The sublayers can vary in thickness such that the optical coating layer reflects light from the ambient environment through the glass layer.
