Unlike a backlit tablet display, Kindle Paperwhite guides light towards the surface of the e-ink display from above so that the light never shines directly towards your eyes, allowing you to read comfortably without eye strain. The built-in light illuminates the screen more evenly than a book light or lighted cover.

Display is very nice. The text is completely readable in all lighting situations that I have tried so far, and from any angle. The backlighting is very effective and satisfactory. The backlighting is not needed in bright sunlight (obviously), but the Kindle does not seem to sense ambient light and adjust backlighting automatically, so if you use it outdoors then I think you need to remember to turn down the backlighting in order to save some battery life. (Or maybe the draw on the batteries from the LED's is so little that you don't need to worry about it). The whiteness of the display is greatest when the backlighting is at maximum. When it is turned to minimum then the screen is more of a cream color. Many of the comments to this version of the Kindle have focused on the pros and cons of this new backlighted display. I do not find the LED's at the bottom of the screen noticeable at all. If you tilt the Kindle and look for them, you can see them. The slight shadowing at the very bottom of the screen that results from the position of the LED lights is only visible in certain combinations of ambient lighting and backlighting and is not at all distracting to me. When I have looked for it, the very small area of shadowing seems to always be just below the last line of text in a book anyway so I don't feel that it is serious. It is appropriate that the backlighting is receiving a lot of attention on this new model, and it was a big part of the reason for my own purchase as well. To me, overall I give the backlighting a score of 95, recognizing that the technology will likely improve and a couple of years from now there will certainly be a new model without this minor artifact.
