Abstract: A dot matrix light-emitting diode (LED) backlighting light source for a wafer-level microdisplay includes a substrate, multiple LED sets arranged at spaced intervals, a first electrode assembly, and a second electrode assembly. The multiple LED sets have multiple LEDs spaced apart and aligned in a first direction. The first electrode assembly and the second electrode assembly are formed on the multiple LED sets to connect the LEDs of the multiple LED sets in series along the first and second directions to constitute a dot matrix LED light source. Upon manufacture of a wafer-level microdisplay, the dot matrix LED light source can be directly packaged and assembled in a microdisplay, rendering the advantages of compact size and low production cost.

Abstract: A dot matrix light-emitting diode (LED) backlighting light source for a wafer-level microdisplay includes a substrate and a bonding layer, multiple LEDs arranged at intervals, a first electrode assembly, and a second electrode assembly sequentially formed on a top surface of the substrate. The first electrode assembly and the second electrode assembly are connected in series to the multiple LEDs to constitute a dot matrix LED light source, which allows to be directly packaged and assembled in a microdisplay in production and is advantageous in reduced size and lower production.
