This paper proposes new micro-LED display fabrication processes. GaN micro-LED and monocrystal Si CMOS chips with pixel circuit to drive LED are mounted in an array shape on a flexible substrate using laser lift-off processes. The emission intensity of LED could be successfully controlled by pulse-width modulation.
