Abstract
Integrated active-matrix light emitting pixel arrays based displays and methods of fabricating the integrated displays are provided. One of the methods include: forming first color light emitting diodes (LEDs) and respective intermediate metallic layers on a first substrate, integrating the first color LEDs with pixel circuits in a backplane device, injecting laser pulses into particular first color LEDs, such that each particular first color LED is individually separated from the first substrate and locally bonded with a respective pixel circuit through a respective intermediate metallic layer, and removing the first substrate from the backplane device. The backplane device bonded with the particular first color LEDs can be further bonded with other different color LEDs formed on other substrates. Other first color LEDs without exposure of the laser pulses are removed with the first substrate and can be further used to integrate with another backplane device bonded with another color LEDs.
