1. A light emitting diode (LED) apparatus comprising:
a substrate;
one or more light emitting diodes (LEDs) that are in contact with a top surface of the substrate and bonded to the substrate;
one or more light-transmissive layers disposed over the substrate and the one or more LEDs; and
one or more dark layers disposed over the one or more light-transmissive layers,
wherein the one or more dark layers are arranged so they do not contact the substrate,
wherein a top surface of the one or more LEDs is higher than or coplanar with a top surface of the one or more dark layers, and
wherein a region above the one or more LEDs is substantially or completely devoid of the one or more dark layers.
