1. A light emitting structure comprising:
a group of light emitting diode (LED) devices;
a group of reflective bank structures, each reflective bank structure being a continuous cone-shaped structure including a bottom surface completely spanning underneath a corresponding LED device and sidewalls extending from the bottom surface and laterally surrounding the corresponding LED device;
an insulating layer spanning underneath the group of reflective bank structures; and
a corresponding group of vias extending through the insulating layer and in electrical contact with the group of reflective bank structures, wherein each via connects with the bottom surface of a corresponding reflective bank structure.
