Well, they may have at some point. Dunno if they still do. Good luck buying one (especially ONE). I guess you can put out an RFQ, but unless somebody has stock, you won't be getting one. Nobody's going to turn up a line to make ONE panel for you, especially not Sharp or NEC, at least not at any price you're willing to pay.
Panel interface appears to be LVDS/OpenLDI/PanelLink. This is quite common internally but is not a consumer standard. You'll need some sort of scaler/driver board. They're not overly complex, but they can cost a pretty penny. Somebody did recently find some on eBay direct from China for like $25 that took DVI or analog RGB (VGA). YMMV with those.
Honestly, I'm far more intereted in the NEC one at 2560x1600. That's an actual improvement over what I had 10 years ago.
