Lenovo is showing a new transparent phone (the S-800). Is it an OLED?

Update: This phone indeed uses a transparent PMOLED!

Lenovo is showing off a new phone, the S-800, which uses a transparent color display. We don't know anything about this phone beside some photos - including what kind of display it uses. It could be a transparent OLED...

Lenovo are already using AMOLED displays in two phones: The LePhone and the Music-Phone.
