The electric driving of 3×3 electrochromic passive-matrix displays, based on porous TiO2 films with surface-attached viologen molecules, is studied. A nonuniform contrast between dark and light pixels is obtained by a well-known addressing method for liquid-crystal passive-matrix displays. An alternative addressing method is developed. The method is capable of displaying arbitrary image patterns with uniform contrast.
