Flexible, paper-like display technology based on “eink” concept:

“An Electronic Paper Display is a display that possess a paper-like high contrast appearance, ultra-low power consumption, and a thin, light form. It gives the viewer the experience of reading from paper, while having the power of updatable information. EPDs are a technology enabled by electronic ink – ink that carries a charge enabling it to be updated through electronics. Electronic ink is ideally suited for EPDs as it is a reflective technology which requires no front or backlight, is viewable under a wide range of lighting conditions, including direct sunlight, and requires no power to maintain an image.” (from the E Ink corporation’s page on EPDs)
