The small display isn't scanned though, it's phosphor on silicon. It's also about 6x brighter than the empeg display for just this reason (the module has a brightness control; FYI, the pictures are with the brightness set to level 2 (of 7), but there's no filter in front of the screen at the moment.

The empeg display glass alone costs around 40-50 quid in small quantities. This is a module including PSU (it still needs something like 50v to light stuff up), controller, etc.
