Claim 9:
10. A high-density light emitting diode (LED) display comprising:
a backplane substrate comprising anode contact pads and cathode contact pads;
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; and
the electrically conductive metal is electrically connected to the cathode contact pads through a metal-filled cathode via; and

a color conversion region overlying the transparent electrically conductive region, wherein the color conversion region comprises:
a color conversion pixel overlying a first portion of the transparent conductive oxide region and overlying each of a respective LED;
a reflective metal region overlying a second portion of the transparent electrically conductive region; and
a metal between each of the color conversion pixels.
