Just looked at the wikiand read about the DSI connector but there are only phone screens listed and not any screen made for using with the pi.
Is there already a screen out there which uses the DSI connector without anything else (not like the buck/boost converter for the iPhone screen)
[As of Sept 8/15 this answer is defunct, but I'll it around for anyone interested in the historical tidbits...]
As noted here and at the end here that connector isn't good for much except potentially a proprietary screen from the Foundation, since there aren't any (public) drivers for it.
There are a few pics around of a demo screen ([1] [2]) that was on display by the Foundation (and Farnell?) at a convention last year, but after searching the Foundation's own blog (for "DSI"), where stuff like this is announced, it seems that screen is still not for sale.
Also at the end of that second Foundation forum there is a quick reference to EMI (electromagnetic interference) problems, so at this point it could turn out the whole thing is infeasible.
The Raspberry Pi foundation has announced that The official Raspberry Pi touchscreen display is now available.
If you want to use it with the older Model A or B Raspberry Pi's however, there are some issues. Although it seems to be electronically compatible, at least one Official Supplier (Farnell's Element14) website says that:
the display will technically work with the Model A and Model B boards (connecting it to the DSI port on the Pi board), however the mounting holes on the back of the display will only line up with the newer board design (A+, B+ and Pi2).
So it is only fully compatible with:
- Raspberry Pi 2 Model B
- Raspberry Pi Model B+
- Raspberry PI Model A+
