US 12,218,298 B2 · Display panel and method for making the same

Abstract

A display panel includes a substrate, a plurality of conductive components on a surface of the substrate, a plurality of light-emitting diodes. The conductive components are on a surface of the substrate and spaced apart from each other. Each conductive component includes a first conductive part and a second conductive part. The second conductive part is electrically connected to the first conductive part. A projection of the second conductive part on the surface at least partially overlaps a projection of the first conductive part on the surface. Each light-emitting diode includes a binding electrode, and the binding electrode is electrically connected to the second conductive part. The first conductive part is made of metal; the second conductive part is made of a transparent conductive oxide. The binding electrode is made of metal. A eutectic material is formed between the second conductive part and the binding electrode.
