In 2021 The Korean government launched a new project that aims to develop technologies for the production of OLED microdisplays for AR applications. The project is led by AP Systems (APS Holdings), and aims to produce a direct emission OLED microdisplay with a resolution of 4,000 PPI by 2024.
According to reports from Korea, APS Materials has managed to develop a 1,000 PPI FMM mask, and is now building a new R&D line that will be used to produce direct emission OLED microdisplays using FMM technology. The new APS production line will include OLED deposition and encapsulation.
