摘要： In an electrochromic display comprising a back plate electrode, a plurality of display electrodes, and a reference electrode available for maintaining the potential of the respective display electrodes at a fixed value, there is provided a detector for sensing the counter electromotive force which is developed between the display electrodes and the reference electrode in a manner such that there is created a remarkable difference in the output voltage signal thereof between in the colored state and in the bleached state. Therefore, the output signal from the detector indicates whether the electrochromic display is held in the colored state or the bleached state.

摘要： A plurality of segment electrodes are aligned in an electrochromic display device for displaying an analog value in a bargraph fashion. When the analog value to be displayed increases, a coloration drive signal is applied only to the segment electrode which should be changed from the bleached state to the coloration state. Contrarily, when the analog value to be displayed decreases, a bleaching drive signal is applied only to the segment electrode which should be changed from the coloration state to the bleached state. Remaining segment electrodes do not receive any drive signals in transition of the displayed value.

摘要： An additional electrode is provided for developing a secondary electrochromic phenomenon on a counter electrode apart from the major electrochromic phenomenon which is developed between one or more display electrodes and the counter electrode. Current flows from an additional electrode to the counter electrode in developing the secondary electrochromic phenomenon. Coloration of the counter electrode, where the magnitude of an overvoltage of the counter electrode is small is stabilized to thereby enhance electronic properties of the electrochromic display. The material of the additional electrode is selected from metals having an appropriate ionization tendency with respect to an electrolyte, such as Mg, Al, Zn, Cr, Fe, Ni, Sn, and Pb, or a combination thereof. Otherwise, the material of the additional electrode is selected to be an inert material with respect to the electrolyte such as Ag, Au, Pt, Pd, In.sub.2 O.sub.3, and SnO.sub.2 or a combination thereof. The combination which is composed of both the appropriate ionization tendency metals and the inert metals can be available for the additional electrode. The electrochromic display can be controlled under one of several groups of driving techniques consisting of a potentiostatic driving, a constant current driving, and a constant voltage driving method.
