…My heart’s in Accra » Negroponte and the $100 Laptop: "The display, though, is harder. The first idea was a projector - a screen would be a white sheet of cardboard, and the image would be created by a small set of LEDs. It’s too fragile for use in the field. So Negroponte went back to looking at LCDs. Much of the power consumption of a LCD display comes from running color filters. Negroponte says you can run a display in two modes, a higher power color one, and a brighter, lower power black and white display. In low power mode, the laptop should draw less than 1 watt."
