Philips spin-off Liquidvista is currently working on an electrowetting display. While this sounds like the light show you get when you pee on an electric blanket, it is not. Instead, it is a system that expands or contracts a drop of ink or oil under glass to draw one pixel. When contracted, the ink "disappears."

Right now the system is only monochrome, but they expect color systems to appear soon and it reduces over all power usage and is considerably brighter than most modern display technologies. What happens, we ask, when the glass breaks? Does your screen leak like a .50 cent Bic?
