An e-book is an indispensable gadget for book lovers. Of course, she does not have the charm of a paper book, concluded in the unhurried turning over of living pages that smell of stories. But you can carry a whole library of free books with you.
Why an e-reader and not a smartphone or tablet? Because other devices have a great burden on vision. In addition, the e-book will last for a long time, plus more convenient navigation.
Screen types: LCD and E-ink. LCD - liquid crystal display, the advantage is a clear, bright image. But the screen glows and flickers, which makes the eyes tired. Therefore, we will focus on the type of E-ink display - the so-called "electronic paper" or "electronic ink". This is an imitation of a regular printed book. The screen consists of microcapsules filled with white and black granules. The old generation of E-ink displays have a minus - the colors are not so saturated, the black is not too bright, the white has a grayish tint. Therefore, there is a special indicator "grayscale" - it should be 8 or 16 shades, not lower. The latest generation of E-ink display is Vizplex.
The display can also be black and white and color. A black-and-white display is enough to read books, but a color one is needed to view photos and videos.
The size of the reader depends solely on your preference. It is more convenient to read from a large screen, but at the same time the book is heavier and has more power consumption. Plus, it won't fit in a small handbag. The optimal size is considered to be a screen with a diagonal of 6 inches or 15.24 cm (one inch equals 2.54 cm).
The screen resolution (dots per inch) depends on the size of the screen. The higher the indicator, the better the image quality. For a size of 5-6 inches, the optimal resolution is 600 * 800 pixels.
Note the support for file formats. One of the most popular file formats on the websites of Russian-language libraries is the FB2 format - it converts electronic versions of books into XML documents.
In addition, e-books have additional options: touch screen - turning pages by pressing the screen itself, built-in backlight for reading in the dark, player, voice recorder, etc.
