Abstract
An electro-optic display has a viewing surface through which a user views the display, a bistable, non-electrochromic electro-optic medium, and at least one electrode arranged to apply an electric field to the electro-optic medium, the display. The display comprises at least 10 micromoles per square meter of the viewing surface of at least one redox compound having an oxidation potential more negative that about 150 mV with respect to a standard hydrogen electrode, as measured at pH 8.
