LED display module and method of making thereof

A light emitting diode (LED) assembly, comprising:

• an LED array, a passivation layer disposed about the LED array, and an array of metal pads,
• wherein the LED array comprises a plurality of LED chips, each LED chip comprises a first terminal and a second terminal,
• wherein the first terminal of each LED chip in the LED array is electrically coupled to a first network of conductive tracks, and
• the second terminal of each LED chip in the LED array is electrically coupled to a second network of conductive tracks,
• wherein each metal pad in the array of metal pads has a first surface in contact with the passivation layer and a second surface positioned outside of the passivation layer,
• wherein the first terminal and the second terminal of an LED chip are respectively electrically coupled to the first surfaces of two metal pads in the array of metal pads,
• wherein the first network of conductive tracks and the second network of conductive tracks comprise traces disposed in a planar direction and in a vertical direction in the passivation layer, and
• wherein the passivation layer comprises one or more dielectric materials.
