OLED Could Be Apple Tablet’s Secret Solution

An OLED display would be a pricey, but perfect, screen for e-book reading on a tablet, like the one Apple is rumored to be announcing later this month.

If Apple were to implement a reading mode with a black background and light-colored text, then an OLED screen would be extremely energy efficient. That’s because OLEDs consume power differently than LCDs; they only use power when pixels are turned on. That means blacks won't consume any energy (like they do with backlighting in LCDs), and such a reading mode would substantially preserve battery life, an analyst explained to Wired.com.

"I would expect when they use OLED to turn to one mode, called OLED display mode, and make most of the background black and make words white, green or red or some other colors," explained Jennifer Colegrove, an analyst with DisplaySearch, a research firm that focuses on the display industry.
