Abstract
An electrochromic display module employing a unique combination of architecture and electrochromic composition to provide an extended life to the module. The architecture may involve the use of an extended seal about a perimeter of a display portion where the composition is located. In this manner, the rate of solvent leakage from the composition may be substantially reduced. Additionally, the electrochromic composition itself may make use of particular low volatility solvents and constituent combinations so as to discourage the amount particle generation therein. Ultimately, an electrochromic display module having a useful life of more than about 3 years may be provided.
