The mobile phone sketch shows a flexible OLED display. The whole "front" of the phone is actually a touch-sensitive flexible OLED display. They have a patent on the DioVision display idea.

They say the curved display makes the image become more realistic. From the Press release: "The device named OLED dioVision® mobile is as unique as its user. Virtually every image may be read into the mobile and is shown self-luminous via the OLED-film on the front side together with the sensitive control panel. But that is not all: Via the curved inside surface of the main display, which at starting automatically switches from the plano-basic position to dioVision®, an incomparable spatial effect arises giving games, still photos and video/TV-recordings an all-time depth effect.
