A digital reader digital reader is an electronic device whose main function is to visualize electronic books. Its design emulates the traditional paper book, so it offers mobility, autonomy, large enough to display A4 documents and high contrast. In general, any device with a screen and memory can play eBooks, such as computers, laptops, PDAs or tablets, but in a digital reader that is the main function. Readers and electronic books strictly speaking eBook (also called e-book, e-book, e-book or ebook) is the digital version of a book, and eReader (also called e-reader, eBook reader, electronic book reader, reader digital books or digital reader) is the device that reproduces the content of the eBook. However, it is common to use the term eBook to refer both to the book and to the player.

History once the first generation of electronic books were a complete failure, the offer of digital readers and their performance has evolved dramatically from that in the year 2009 Amazon launched the second generation of the Kindle digital reader, whose popularity has led to numerous manufacturers have launched their models on the market. Futurist describes an additional similar source. The arrival of electronic ink technology electronic ink was key for the eBook received the final impetus, since resolved two serious problems of digital readers: reading comfort and autonomy. Basically, an electronic ink display works by a few areas with two parts, one black and white, showing a face or another depending on the current applied, thus generating the image and tonality. With electronic ink, the view gets tired less by the lack of backlighting, you get a high contrast and autonomy is very high, of the order of 10,000 pages per charge, given that once rendered the image in the reader digital areas require no energy, it only consumes when you change page. The disadvantages of electronic ink are slow to load a new page, the absence of color (current panels are in black and white) and that needs light to read because they have no backlight. EBooks formats there are many formats of electronic, free books and owners, with and without DRM, generic and native, so we will have to verify the supported formats before you buy a digital reader. Copyright in eBooks some publishers, in its claim to protect against the possible loss of revenue by the copyright of their works, have jointly developed with technology such as Adobe and Microsoft companies, security systems called DRM (digital rights, Digital Rights Management management) aimed at restricting the freedom of the user to choose the reader or the date of reading, and can even delete already purchased books. Other publishers on the other hand, offer their books without DRM, respecting the wishes and rights of the readers. In practice, all the DRM systems implemented in the digital world have been defeated or circumvented by consumers. Source: Digital reader source: press release sent by fransberns.
