Abstract
Micro-LED array display devices are disclosed. One of the micro-LED display devices includes: a micro-LED panel including a plurality of micro-LED pixels; a CMOS backplane including a plurality of CMOS cells corresponding to the micro-LED pixels to individually drive the micro-LED pixels; and bumps electrically connecting the micro-LED pixels to the corresponding CMOS cells in a state in which the micro-LED pixels are arranged to face the CMOS cells. The micro-LED pixels are flip-chip bonded to the corresponding CMOS cells formed on the CMOS backplane through the bumps so that the micro-LED pixels are individually controlled.
