Displays using direct light emission from microscale inorganic light-emitting diodes(μILEDs)have the potential to be very bright and also very power ***-throughput technologies that accurately and cost-effectively assemble microscale devices on display substrates with high yield are key enablers forμILED *** stamp transfer printing is such a candidate assembly technology.A variety ofμILED displays have been designed and fabricated by transfer printing,including passive-matrix and active-matrix displays on glass and plastic substrates.
