Well, after some research on conrad (german radio shack :-)) and ebay found something.
This small display uses the video connector. So it`s not too sharp. But small, cheap and really bright.
The price was about 25 € including shipping and vat.
This picture is not too good. The display is sharper than it seems.
Yes, i started Open Arena 🙂 of course just for the test!
Well, i have to use my screwdriver….
Well, here is just the panel with driver board itself.
It`s really small and has 2 screw holes on each side for a easy fit.
