China-based display maker CSoT demonstrated several new OLED display prototypes and technologies at SID 2019, and this great new video shows these displays in action.
First up is a 31" 4K (3840 x 2160, 144 PPI) AMOLED that was produced using an ink-jet printing process on an IGZO substrate. The peak brightness is 200 nits and the refresh rate is 120 Hz. This seems to be the same panel announced in March 2018 by Joshua Printing Display Technology (established by CSoT and Tianma in 2016). The display has some noticable defects.
Second up is a glass-free 3D (parallax barrier) transparent OLED. This panel is a 31" 1920x1080 (FHD) panel that features a 60Hz refresh rate and a brightness of 100 nits. The transparency is only 20%.
