Claim 0:
1. A high-density light emitting diode (LED) display comprising:
a backplane substrate comprising anode contact pads and cathode contact pads;
an interconnection region overlying the backplane substrate, wherein the interconnection region comprises:
a frontplane interconnection region comprising frontplane vertical interconnects;
a backplane interconnection region comprising backplane vertical interconnects; and
a hybrid bonding interface between the frontplane interconnection region and the backplane interconnection region, wherein,
the frontplane vertical interconnects are aligned with respective backplane vertical interconnects;
each of the vertical interconnects is electrically connected to an anode contact pad or to a cathode contact pad; and
each of the frontplane vertical interconnects and the backplane vertical interconnects comprise copper-filled vias,

an LED region overlying the interconnection region, wherein the LED region comprises LEDs and an electrically conductive metal between each of the LEDs;
a transparent electrically conductive region overlying the LED region, wherein the transparent electrically conductive region is electrically connected to each of the LEDs and to the electrically conductive metal between each of the LEDs;
a dielectric region overlying the transparent electrically conductive region; and
a color conversion region overlying the dielectric region, wherein the color conversion region comprises:
a metal layer overlying the transparent electrically conductive region; and
a color conversion pixel formed within the metal layer and overlying each LED.
