Patent attributes
Integrated active-matrix light emitting pixel arrays based displays and methods of fabricating the integrated displays are provided. One of the methods includes: forming a plurality of light emitting elements on a substrate, each of the light emitting elements including multiple semiconductor layers epitaxially grown on the substrate and being configured to emit light with a single color, integrating the light emitting elements formed on the substrate with a backplane device, such that each of the light emitting elements is bonded and conductively coupled to a respective pixel circuit in the backplane device, and then removing the substrate from the light emitting elements that remain integrated with the backplane device. Active-matrix multi-color pixel arrays can be formed by sequentially integrating different color light emitting element arrays on the backplane device or depositing different color phosphor or quantum dot materials on single color light emitting element arrays integrated on the backplane device.
