An e-book reader, also called an e-book device or e-reader, is a portable electronic device that is designed primarily for the purpose of reading digital books and periodicals.

An e-book reader is similar in form to a tablet computer. A tablet computer typically has a faster screen capable of higher refresh rates which makes them more suitable for interaction. The main advantages of e-book readers are better readability of their screens especially in bright sunlight and longer battery life. This is achieved by using electronic paper technology to display content to readers.

Any device that can display text on a screen can act as an e-book reader, but without the advantages of the e-paper technology.
