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.

We worked on Kindle Paperwhite for over two years to perfect the uniformity of the built-in light, flattening out a fiber optic cable into a sheet, and nanoimprinting to ensure perfectly even distribution of light. Our design uses nanoscale optical diffractive patterns to enable tight control over the direction of the light. Enjoy reading with exceptional lighting uniformity and evenly balanced whiteness across the entire display. 

Your eyes adapt to the amount of light around you, so you'll prefer dimmer light when reading in a dark setting and brighter light when reading in well-lit surroundings. You can adjust the brightness of Kindle Paperwhite across a wide spectrum - from low light to full brightness - so you can read comfortably in any setting.

Because our patented technology enables fine-grain control over where the light is diffused, Kindle Paperwhite uses low-power LEDs, requiring very little power to evenly illuminate the entire screen.
