Even as the processing power and download speeds of mobile devices surge, one component still lags behind: the screen. LCD panels use significantly more power than any other component of a phone or tablet because of their need to pump out bright light to form an image. The only practical alternative is e-ink, the technology used in the Amazon Kindle; it consumes orders of magnitude less power but sacrifices color and the ability to change images fast enough for video playback or smooth game play. Now, after years of waiting, alternative technology that promises the best of both approaches is finally edging closer to commercialization. During a recent visit to mobile chipmaker Qualcomm’s headquarters in San Diego, Technology Review tried out a full-color, 5.7-inch Android tablet with a display that offers rich colors under bright light, close to those of an LCD and not unlike the pages of a magazine.
