Inspired by the paper of "Fabrication of full-color GaN-base light-emitting diodes on nearly lattice-matched flexible metal foils" from TOKYO University, Japan, the author collected other related papers for exploring the possibility of growing micro LED devices by Magnetron Sputtering Deposition (MSD) and deposited micro LEDs directly onto glass substrate with low-temperature ploy-silicon (LTPS) or Indium-Gallium-Zinc-Oxide (IGZO) TFT devices without using the popular mass transfer process/technology for forming micro LED displays.
