At the twist of its casing, an ultrathin OLED display is revealed, in this portable DVD player concept. No word yet on if this gadget will go into production.

Designer Yeon-shin Seung says he plans to use Sony's full-color flexible organic electroluminescent display on this device because of the screen's thin and lightweight form factor. Here's hoping that he doesn't use the ancient DVD format is a playback medium, eschewing that old fossil for a dual-format Blu-ray and HD DVD player.
