There is a growing consensus that microLED will become the next major flat panel display type. At present, leading companies are demonstrating steady progress against the technological challenges that historically impeded the commercialization of microLED displays, such as mass transfer in manufacturing and fabrication of efficient micron-scale optoelectronic devices. Equally important is the pixel drive circuitry needed to control the microLEDs efficiently and reliably in these displays. Mass transfer for microLED displays most frequently refers to the process used to distribute microLEDs across a panel substrate, but it can also open entirely new advantageous possibilities in backplane design. Mass transfer of microIC drivers as pixel engines for microLED displays is gradually receiving increased attention as a path toward unmatched efficiency, dynamic range, and brightness.
