ABSTRACT:
An organic light-emitting diode (OLED) pillaged display device, comprising: a) a substrate having a substrate thickness; b) an array of pixels comprising one or more OLED light-emitting elements, each light emitting element having a first electrode formed over the substrate, one or more layers of organic light-emitting material formed over the first electrode, and a second electrode formed over the layer(s) of organic light-emitting material to define a light-emitting area; the array of pixels having a characteristic spacing between neighboring pixels in the array, wherein the characteristic spacing is the maximum distance between corresponding points in neighboring pixels in an array dimension; c) a cover located over the substrate having a cover thickness; and d) a scattering layer located between the substrate and the cover; wherein light from the OLED light-emitting elements is emitted either through at least one of the substrate or the cover, and wherein the thickness of either the substrate or the cover through which light is emitted is less than or equal to two times the characteristic spacing.
