ABSTRACT:
A controllable electrochromic indicator device is disclosed which includes two electrodes, an electrochromic layer and an adjacent charge-carrier-transmitting insulator layer situated between the two electrodes and at least one of the electrodes being deposited on a supporting plate and at least one of the electrodes being transparent. The charge carrier transmitting insulator layer is a good ion conductor and functions to almost completely block the flow of electrons. At least one of the electrodes is non-polarizable and is disposed in direct contact with the ion conductor.
