Is it The Future of Displays?
Conventional backlit flat displays work with the principle of emitting light. E-paper or electronic paper (also called EPD: Electronic Paper Display) are display devices that reflect light just like ink on paper. Just like ordinary paper, the characters on an e-paper are visible even in direct sunlight. E-papers are perfect displays since the image remains fixed even after the power is switched off, thus consuming extremely low energy.
