Citizen has developed something it's calling the "memory liquid crystal," a new passive matrix LCD that can retain an image even when powered off. According to Citizen, the display's inorganic membrane, combined with an angled orientation, keeps the crystals frozen in position without power having to be maintained. The five-volt, non-backlit display isn't going to take the place of your LCD TV anytime soon, but is planned for use in point-of-sale applications, watches and cellphone auxiliary displays.
