Optoelectronic displays using uniformly spaced arrays of semi-sphere light-emitting diodes

摘要

Light-emitting p-n junction diode elements in the form of ion implanted spheres are mounted to a surface of an insulating substrate member. Metallic coatings are provided on both the semiconductor material and the implanted region for electrical contact. A transparent conductor material is then further disposed over the diode structure connecting diodes and forming an array.
