ELECTROCHROMIC FORMULATION WITH AT LEAST TWO DYE SYSTEMS METHOD FOR PRODUCTION THEREOF AND ELECTROCHROMIC COMPONENT

摘要

The present invention relates to electrochromically active formulations for flashing electrochromic displays, in particular for those which, in addition to the flashing a durable symbols can switch to the flashing indication. The formulations contain at least two chemically different ink systems. The formulations are characterized in that the first color system in the case of a low voltage can be reversibly, that is to say to the flashing symbols are displayed, is suitable. The second ink system is in the case of a higher voltage can be activated and, on account of its bistability and irreversibility for the permanent indication of symbols suitable.
