1. An illuminator comprising:
at least one stack of layers including at least one light emitting layer; and
multiple groups of phase scrambling particles deposited on an individual light emitting layer so that at least one of the light emitting layers has the multiple groups, wherein each group has the particles spaced from each other, wherein the multiple groups comprising intentional variation between at least two of the groups in at least one of: sizes of the particles, at least one material forming the particles, and spacing between the particles.
