This is another example of an electrotactile (or electrovibration) display. If you'd like to read more, I did a writeup about a competitor called "Senseg" from Toshiba a while back: http://www.hizook.com/blog/2010/08/11/electrotactile-arrays-...

Incidentally, they function by stimulating nerve endings -- either through electrical pulses (electrotactile) or vibrations (vibrotactile). Much like the Senseg device I spoke of, the linked device is probably a variant of vibrotactile where the vibrations are generated by electrostatic forces (think "capacitor forces") via transparent electrodes on the front of the display.
