Abstract (en)

[origin: DE19804332A1] The present invention relates to a measuring and electrochromic display system for electrically measured variables, wherein said system comprises an electrochromic substance located between two electrodes having their base surface determined by a short and a long axes. One of said electrodes is transparent and one electrode has a finite surface resistance. The signal is measured by modifying the voltage difference between the two electrodes along the long axis.
