Sharp unveils LCD panel with integrated memory function

Sharp has developed LCD screens with a memory function that makes it possible to save the displayed content after the power supply is cut off. A number of prototypes (in 1.7-, 2.4-, 6.1- and 14.1-inch sizes) was showcased at the FPD International 2008 show in Tokyo, with just the two small versions being in color.

Sharp sees its screens as a possible new alternative to e-paper, to be used as electronic price tags in supermarkets, in public signage systems or as electronic menus in restaurants. The company currently conducts tests in a supermarket in Osaka, which can now change prices easily via the wireless LAN the panels are equipped with.

Sharp apparently denied giving technical details but said their panels are based on cholesteric LCD material and that they can only be used indoors (at temperatures between -25 and +55°C). It’s unknown if the company will ever commercialize its technology.
