Patent ID: 8557616

Claim:
A method for manufacturing a monolithic Light Emitting Diode (LED) micro-display panel on an Active Matrix (AM) panel, comprising: providing a substrate of the LED micro-display panel; overlaying a plurality of layers of material on a surface of the substrate, the plurality of overlaying layers of material being configured in combination to emit light when activated; patterning the plurality of overlaying layers of material by removing a part of each overlaying layers all the way down to the surface of the substrate; depositing a current spreading layer on the patterned plurality of overlaying layers of material and surface of the substrate; providing a metal multilayer on the current spreading layer; patterning the metal multilayer in such a configuration that a first portion of the metal multilayer, which lies on the patterned plurality of overlaying layers of material, and a second portion of the metal multilayer, which lies on the surface of the substrate are conductively disconnected, thereby forming the monolithic LED micro-display panel; and combining the monolithic LED micro-display panel with the AM panel, said AM panel comprising a plurality of active control circuit chips with conductive solder material, said combining comprising flip-chip bonding the monolithic LEDs to the active control circuit chips via the conductive solder material, wherein each of the monolithic LEDs is electrically insulated from one another and independently controllable by corresponding ones of the active control circuit chips bonded thereto.
