Samsung shows a concept translator that uses a transparent AMOLED

Samsung has published a new concept translator device (which they call the 'real translator') - which uses a transparent display (which can be an LCD or an AMOLED). The idea is that when you talk to someone you can get real-time translation (via voice recognition) on the display, and because it's transparent it can show translations for both speakers at the same time
