"Thats 3 for Sony, ... alas no longer Japanese?"
At some point, many years ago, there was S-LCD. Company making screens. It was owned by SONY and........Samsung. It has since then changed to entirely Samsung so SONY could get snuggly with......Sharp.
At about that time, Philips and LG had LG-Philips Displays. I think it is only LG now.
I know it does not help OP, but just to make brand loyalty a little less convincing.
