Dot matrix light-emitting diode backlighting light source for a wafer-level microdisplay and method for fabricating the same

A dot matrix light-emitting diode (LED) backlighting light source for a wafer-level microdisplay, comprising:

• a substrate;
• an LED epitaxial layer formed on a top surface of the substrate and having multiple LEDs arranged at intervals to take the form of a matrix;
• a bonding layer formed between the top surface of the substrate and bottom surfaces of the multiple LEDs;
• a first electrode assembly formed between the bottom surfaces of the multiple LEDs and a top surface of the bonding layer;
• and
• a second electrode assembly formed on top surfaces of the multiple LEDs;
• wherein the first electrode assembly is connected in series to the multiple LEDs in a horizontal direction and the second electrode assembly is connected in series to the multiple LEDs in a vertical direction perpendicular to the horizontal direction.
