摘要：
Manufacturing fine metal mask (FMM) is one of the biggest hurdles to realize the ultra-high definition (UHD) grade AMOLED displays for smartphone and augmented reality (AR). We have developed the state-of-the-art material and processing technology to achieve 800ppi or higher-resolution FMMs. The Invar thinning and the thermal damage-free laser ablation process realized us achieving the FMM for UHD displays.
