"Paperwhite guides light toward the surface of the display with its built-in front light—unlike back-lit tablets that shine in your eyes" [1]
I have a Kindle Paperwhite, and was surprised to read this article, because I have no trouble sleeping. Apparently the way the light works is the reason for this :)

- HackinOut 12y agoThanks for the reference. I am not sure that backlights are the problem though. Just imagine shining a light behind the page of a book (although it's hardly comparable to the level of transparency of Liquid crystals). I would rather bet on the color of the light (warm vs cold). Maybe it's all in my head but when it's sleep time, I hate cold bulbs (and LCDs) while I am not bothered by warm light like a candle or a warm bulb. Furthermore, it seems to me that with the Paper White's light guided "on the surface of the display", the light shines as much in towards your eyes as it does towards the screen...
