ABSTRACT:
The operating life of an electrochromic display cell is greatly lengthened by incorporating a buffer in the electrochromic solution. The buffer prevents local changes in pH which are shown to be responsible for termination of the operability of electrochromic display cells after a limited number of display cycles.
