The newest Amazon Kindle e-reader will have front-lit "Paperwhite" technology that works in sunlight and in dark rooms. Amazon announced its latest e-reader today (Sept. 6).
The e-ink in reader devices generally works by reflecting light, so it doesn't work in the dark. Meanwhile, the LCD displays people see on their smartphone or computer screens are backlit, which means light comes out from the display. In a front-lit display, light points down at the display, away from the eyes. In Paperwhite, the display guides LED light underneath an anti-glare layer before it's diffused across the screen.
The front-lit technology makes Kindle Paperwhite devices comfortable to read for hours, according to Amazon. Users are able to adjust the brightness of the Paperwhite light as they like.
The new display boasts a higher resolution and has 25 percent greater contrast than previous Kindles, Amazon officials said. A Kindle Paperwhite but should last eight weeks with the light left on, according to Amazon.
The Kindle Paperwhite will cost $119, while a Paperwhite device with a paid-for 3G wireless connection will cost $179. Both devices start shipping Oct. 1.
