Limited-color OLEDs could operate with 40 percent less power, look just as stunning

You know that fancy flat-panels can display more colors than the human eye / mind can even interpret, right? Thanks to our hard-wired limitations, a certain facet of boffins across the way are developing a method that would scale back the amount of colors used in an OLED screen in order to shave energy usage even further. Johnson Chuang of Simon Fraser University in British Columbia has worked with colleagues in order to conjure up sets of colors that "slash the power consumption of an OLED panel by up to 40 percent, with minimal effect on how people perceive an image." In theory, at least, this breakthrough could lead to longer battery life in cellphones, PMPs and all manners of portable devices. As Chuang puts it: "Say you're running low on battery and you want to use Google maps to get home; switching to an energy-aware color set could make your battery last longer." Don't pretend that doesn't interest you.
