Abstract:
An electronic device may include a packaging substrate having a packaging substrate face with a plurality of electrically conductive pads on the packaging substrate face. A first light emitting diode die may bridge first and second ones of the electrically conductive pads. More particularly, the first light emitting diode die may include first anode and cathode contacts respectively coupled to the first and second electrically conductive pads using metallic bonds. Moreover, widths of the metallic bonds between the first anode contact and the first pad and between the first cathode contact and the second pad may be at least 60 percent of a width of the first light emitting diode die. A second light emitting diode die may bridge third and fourth ones of the electrically conductive pads. The second light emitting diode die may include second anode and cathode contacts respectively coupled to the third and fourth electrically conductive pads using metallic bonds. Widths of the metallic bonds between the second anode contact and the second pad and between the second cathode contact and the third pad may be at least 60 percent of a width of the first light emitting diode die.
