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-readers have a similar form factor to a tablet; usually use electronic paper resulting in better screen readability, especially in bright sunlight; and have longer battery life when compared to a tablet. An e-reader's battery will typically last for multiple weeks. In contrast to an e-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.
Types of electronic-paper displays
All electronic paper types offer lower power consumption and better sunlight contrast than LCDs. E Ink displays do not produce any light by themselves, so some models offer a frontlight for reading in dark areas. E ink: E Ink Corporation's 1st-generation technology, also known as E Ink Vizplex. Although "eInk" may be used to talk about all electronic paper displays, "eInk" and "E Ink" are trademarked by E Ink, which provides the majority of the electronic paper displays used in devices. E Ink Pearl: E Ink's 2nd-generation technology, which has higher contrast and a greater number of different levels of gray than their earlier technology. A further revision of Pearl is Mobius, which uses flexible plastic in the display. E Ink Triton: E Ink's 3rd-generation technology that featured the ability to show color in the display. E Ink Carta: E Ink's 4th-generation technology, which has higher contrast and a greater number of different levels of gray than their earlier technology; the displays have a pixel density between 212 and 300 ppi. E Ink Kaleido: E Ink's colour e-paper display supporting up to 4096 colours, used in various e-readers such as BOOX Go Color 7 and Kobo Libra Colour SiPix: A former competitor to E Ink, which had displays with almost instantaneous page turns. It was acquired by E Ink in December 2012. LG Flex: Electronic paper that allows a flexible screen; is still in development. With these displays, the user is able to bend the e-reader without damaging it and can fold it up to put in a pocket.
Electronic-paper readers come in various sizes. Many small e-readers have display diagonal sizes around , while some of the large commercially available readers have display sizes around A5 () or A4 size ().

Notes: Library DRM compatible – Can be used to borrow e-books from public libraries, e.g. the EPUB and/or PDF formats with digital-rights-management (DRM) are supported. "microSDHC" is the most popular format for external memory cards. Devices which support a different card have that format listed. Listed are only products for which either the product itself or its company is notable, as shown by having a Wikipedia article (without notability notice).
