Energy-aware colour palette

Flat-panel displays based on organic LEDs are likely to become commonplace soon, replacing LCD panels, because they are more energy efficient. However, another potential advantage is that OLEDs use more or less energy depending which colours (hues) are being displayed. This is in contrast with LEDs which use the same amount of energy no matter which hue is being displayed. Research by Johnson Chuang at Simon Fraser University in Canada suggests that the selection of an energy-aware colour palette could save battery life on mobile devices.
