Abstract
Apparatus and methods relating to display stacks wherein one or more index matching layers are utilized to minimize reflectance at the boundaries of otherwise adjacent layers. More particularly, the present invention is directed to methods and apparatus relating to a multilayer display stack comprising a glass layer, a first index matching layer, a first intermediate layer, a second index matching layer, a second intermediate layer, and a light emitting display panel wherein: the glass layer, first index matching layer, first intermediate layer, second index matching layer, and second intermediate layer are each transparent or translucent, and comprise an index of refraction; the index of refraction of the first index matching layer is between the index of refraction of the glass layer and the first intermediate layer; and the index of refraction of the second index matching layer is between the index of refraction of the first intermediate layer and the second intermediate layer. Alternative embodiments may comprise additional index matching layers, additional non-index matching layers, as well as layers other than those described herein.
