Device for reading electronic books – the textbook for shopping computer World

device for Reading electronic books (e-books) is a great device and a great gift for people who regularly read and travel a lot. Helps easy to read not only at home but on the go. The main advantages of reading e-books is their compact size, light weight, matte screen of e-paper, easy for the eyes and niegenerujący harmful reflections of light, and long battery life.

On the market we will find dozens of models of devices for reading electronic books that are offered at the price from 300 to 1500 rubles. Which one to choose? Below we present the main parameters of the reading to which you should pay special attention.

Size, type and resolution of your screen

recommended for reading electronic books must have the display made of electronic paper. It provides for experiences that are close to the classic book page and does not cause much eye strain as reading on the screen of the smartphone or tablet.

readers are used, as a rule, two types of screens, Sr., called E Ink Pearl or newer, and better, called E Ink Carta. If we have a choice of such devices, of course, it is better to choose the model gives a slightly better white e-paper Carta.

the Most popular reader offers currently screen size with a diagonal of 6 inches. However, it is also the device a little more – 8-and even 10-inch. the Screen a diagonal of 6 inches-a seemingly small, but quite for comfortable reading of books and allows you to maintain a very compact size of the entire device. Each reader, of course, we are in a fairly wide range to adjust the size of the displayed font.

If you have good eyesight or do you plan to make frequent use of electronic publications with the illustrations, you should pay additional attention to the screen resolution. The best readers offer a picture of exactly 300 ppi (pixels per inch), a weaker-about 200 ppi, but we still can still buy products on pixel density at 170 ppi. Even this last value, however, is not evil to read conventional books. Today it is very popular and increasingly used by older readers Amazon Kindle 4 & 5 with 6-inch screen E-Ink Pearl on the accuracy of the 167 dpi (800 x 600 pixels).

Lighting

the Older and lower-class readers do not have the additional screen illumination, which means that in their case, at very low light reading books can be a little comfortable. To fix this, you can use the additional LED light bulbs attached to the reader case or book case with built-in lighting. The popularity and development of reading have led, however, to creating devices with built-in doświetleniem of the screen. Thanks to him the image on the screen is simply readable even in the complete absence of lighting in the area, but also more contrast in the mode of daily reading. You should put on the device doświetlanym screen.

Touch screen

Typically, this solution is convenient and sufficient, but in the era of smartphones and tablets touch screen feature also came to read books. Both methods of navigation have their supporters and opponents – as well as touch smartphones, so before buying you should check both solutions, or gently ask the future owner about his reader’s sympathy. Touch reader fit, but it’s best if we often make any notes related to czytanymi books or documents. The physical buttons are, and plus, when it is often said gloves. The latter is more expensive, the consent of all readers – there are touch screen and navigation buttons.

battery life

for Reading e-books are devices that require relatively rare charge. Of course, it depends on how often and how long we reader and built-in communication module (Wi-Fi/3G), but in the case of popular e-readers Amazon Kindle, mainly charging is required every two weeks. This performance was achieved thanks to the use of screens made of electronic paper, which consumes energy only when changing the displayed content, i.e. while scrolling the pages of a book. Because of this, the operation time of reader offers are often not in days, but it expresses the number of pages viewed on a single charge.

Supported ebook formats

There are several formats that allows you to save text, such as with embedded illustrations. In the world of computers is ruled by the text files with MS Word, and PDFs. On the market of e-readers, are leading the other two formats – EPUB (open) and MOBI (mainly used readers Amazon). It is in these two standards most often encountered in shops, e-publishing and, at least one of them must support the intended reader.
