This document discusses electronic paper (e-paper), which aims to create a paper-like display with properties such as high contrast, light weight, and very low power consumption. It describes several types of e-paper technologies being researched, including electrophoretic, cholesteric liquid crystal, electrowetting, and electrochromic technologies. The document also notes desirable features like flexibility and video capability, and applications of e-paper like e-readers, watches, phones, and digital textbooks. Researchers are working to develop full-color e-paper and improve refresh rates to enable uses like e-books and mobile devices.
