TCL's CSoT subsidiary demonstrated curved 31" FHD AMOLED displays at the 18th China High- Tech Fair. CSoT showed three such panels side-by-side, to create a 5760x1080 80" display. The WOLED WRGB panels offer 150 nits brightness (which is rather low).
CSoT are producing those panels in its Gen-4.5 pilot R&D line in Shenzhen. CSoT already demonstrated 31" AMOLED panels in June 2015, it is not clear what is the difference in the new prototypes.
