An anonymous reader writes: E Ink--makers of the zero stand-by power electrophoretic displays used in the first Kindles--thought they were home free, ready to retire on the millions of units being shipped for eReaders. Unfortunately for them, the iPad came along and now every eReader is switching to backlit LCDs despite the fact that you have to charge their batteries daily instead of weekly like when using a E Ink display. The company's new owners--Taiwan's YFY Group--however is landing contracts for a wide variety of applications where zero standby power is still a big advantage, like smartcards and like turning the black back of an iPhone into an auxiliary display that tells you the time, how many waiting emails and messages you have, and remaining battery life all without having to power up the main LCD display. These and a bunch of other new designs are on display at this week's Society of Information Displays (SID 2012, Boston), but you can see them online here.
