Abstract
An electrochromic display cell having in sandwich layered form a first transparent substrate with a plurality of digits each being formed thereon by a plurality of selectively energizable transparent electrodes and an electrochromic layer on each of the transparent electrodes, a second substrate with a plurality of separate and selectively energizable counter-electrodes each being associated with a digit, and a separate electrolyte layer between each counter-electrode and its associated digit. In the preferred embodiment, each corresponding transparent electrode of each digit is interconnected on the first transparent substrate to form groups of commonly energized segments with each group having a single electrical connection to/from the display.
