JOLED is a partnership of four companies. Sony and Panasonic, Innovation Organization (INCJ), Japan Display (JDI). In truth, Sony and Panasonic have very little invested. Voting rights of JOLED is 75% INCJ, 15% is JDI, Sony and Panasonic will each own 5% each.
The good news here is that they are using the OLED printing method rather than LG WRGB vapor method. So eventually the should be able to scale it up to large format from the initial production of phone, tablet and laptop size screens. I wonder if they are using their own printing method or the sealed nitrogen chamber one that Kateeva invented.
