Active Inc., an optical component manufacturer, is working on a transparent liquid crystal optical film as a replacement for backlit LCDs. Based on the scanty information available, it seems to work just like traditional liquid crystal displays, which are transparent until you run a current through them, at which point all the crystals in the liquid align and become opaque. I guess the difference here is that the screen is backlit by ambient light, which is a neat idea with questionable consumer practicality.
