why eBooks can really compete with books.
The screen-reader devices and is one of the key aspects on which to play the future of eBooks, the reason is very simple to understand:
- LIGHT AND FU
The reading of any text involves time and visual attention. If the traditional reading on paper not the question, reading on screen is a crucial ensure readability and a visual stress sustainable . Especially for the second question, the screens on the market until a few months ago ensured unacceptable standard. The screens lcd of which were equipped with all the hardware devices in fact belong to the family of backlit screens: what does this mean?
A very practical explanation, from the profane, the issue could be summarized as follows: a backlit display "live" by artificial light behind the LCD panel in fact there are lamps that emit light and allow components to reproduce the images on the screen. The human eye perceives this as unnatural and it is soon fatigued: this is difficult to stay in front of a screen of a PC or a TV for several hours (and many of us know it very well.)
Fortunately, research has beaten tracks and was able to make alternative screens conceptually opposed to those mentioned, which are more like a sheet of paper to a lcd.
- CHECK THE INK AND INK-
The scientific solution to the problem of achieving ebook reader devices with screens competitive with the paper is a conceptual simplicity disconcerting : want an eBook? then need to create paper and electronic ink.
The technological response to this concept is brutalized e-ink , which were produced not backlit screens that behave just like paper.
E-ink is a real ink beneath the screen-reader devices and which do not appear to require any kind of backlight makes reading this very natural and similar in all respects to that on paper, just like a book, the page is read if there is light, indeed, more light is better and it shows!
A further advantage of this technology is the very low energy consumption: the batteries fail and only the change of page, not when reading. The duration of a load average is about 8,000 page turns, enormous.
The only limit of this technology is the color, in fact, the e-ink screens are only in black and white.
- "... AND THAT'S A GREAT TECHNICOLOR ..." [1]
Even this limit will soon be over: After e-ink technology here is in fact another big-screen not backlit, this time in color: mirasol .
first models to be released in late 2010, but will investigate other bet.
