Fraunhofer researchers have been examining the scaling effects in smaller CMOS technologies and investigating the use of 300 mm backplane processes as part of the "Backplane" project funded by the Saxony State Ministry for Economic Affairs, Labor and Transport. In this context, the researchers have succeeded in making the next major leap forward in development: For the first time, they realized an OLED microdisplay with tiny 2.5 µm pixels (corresponding to 10,000 dpi) at a display diagonal of 0.18 inch. This demonstrated the feasibility of developing displays based on 28 nm small-node technology on 300 mm wafers and realized the world's smallest pixels of an OLED microdisplay.
