Flexible OLED Display Using C-Axis-Aligned-Crystal/Cloud-Aligned Composite Oxide Semiconductor Technology and Laser Separation Technology

摘要

A top-gate self-aligned transistor with excellent characteristics was developed using a cloud-aligned composite oxide semiconductor (CAC-OS). A 1058-ppi 8K4K foldable organic light-emitting diode panel was fabricated using the transistor and employing a novel linear laser separation technology. These technologies enable a shift of production lines from low-temperature polysilicon to CAC-OS.
