Comparison of e-book readers
An e-reader, also known as an e-book reader, is a portable electronic device that is designed primarily for the purpose of reading e-books and periodicals. E-book readers are similar in form to a tablet and usually, refer to readers that use electronic paper resulting in better screen readability, especially in bright sunlight, and longer battery life when compared to a tablet. When disconnected from the web, an e-book reader's battery will last many weeks. In contrast to an e-book reader, a tablet has a screen capable of higher refresh rates which make them more suitable for interaction such as playing a video game or watching a video clip.
Any device that can display text on a screen can act as an e-reader but without the advantages of electronic paper. On the other hand, most e-books are read on devices not specifically designed for reading e-books, such as desktop/laptop computers, smartphones and tablets.
All electronic paper types offer lower power consumption and better sunlight contrast than LCDs. Some offer a backlight to allow for low-light reading. With the backlight turned off, all have a similar appearance to "ink on paper" and are readable in bright environments.
