Mobile Mag reports about a new type of display developed by a company out of Cupertino. This new display requires significantly less power and could boost battery life by up to 50%:
The technology has toned the intensity of the screen's backlight by using a special pixel architecture called PenTile. This system is a specific pattern of blue, green, red, and white pixels mixed with image-processing algorithms, with the whole thing working in concert to cut the backlight intensity.
The key for PenTile is the addition of white light. Other, more traditional displays rely on patterns made up of only blue, green, and red. Adding in the white results in brighter brights and darker darks. The fonts are easier to see and read as well.
Each pixel is individually controlled, so the white can be cranked up or toned down, depending on your backlighting needs, from traditional things like web browsers to more advanced things like high-definition video.
