Why is there no backlight in jetBook?
We deliberately removed the backlight from jetBook’s original specification after a lengthy consultation with ophthalmologists in the US. We were advised that if we wanted to make jetBook closer in experience to a regular book, we should not use any backlight. Similar to the fatigue that comes with computer monitors, if you read by looking at a source of light your eyes get tired within 1-2 hours and you need a longer period of rest to recover. Just like a regular printed-paper book, with jetBook you read in reflected light so the eyes do not get tired (if you get tired just switch the font to a larger size and you may continue to enjoy reading). This is the main reason why the backlight was not implemented.
