Foxconn announced its plans to build a display fab in Wisconsin, USA, in 2017, and following delays the company plans to start operating the new fab by the end of 2020. The plant's designation changed several times - from LCD production (which never made much sense) to R&D and finally and currently to LCD module production.
Foxconn now says that it may also add OLED and Micro-LED production lines in the Wisconsin factory. It did not disclose any more details or timeline, this is certainly not a commitment yet. It is also not clear whether they mean to produce OLED and MicroLED display panels or modules.
