Kyocera EOS concept phone

The most of mobile phones producers try to combine small size of device and big screen. Due to flexible OLED screen this problem can be solved. Such mobile device was introduced on CTIA exhibition by Kyocera. EOS phone is a concept device with QWERTY keyboard and flexible screen. But Kyocera EOS future device is notable not only for its big screen but also for its keypad: the buttons become flat or convex depending on situation. To charge built in battery this phone has piezoelectric elements which transform movement energy to electric one. These ideas are still a long way from realization. But I hope that this future mobile phone will become real in the next few years.
