Typically, electrochromic displays have separate electrochromic and electrolyte layers which add to the complexity and cost of manufacture. ynvisible's patented invention offers a solution that helps tackle performance and production efficiency issues and provides essential production efficiencies to brands that are looking to utilize electrochromic displays in their mainstream consumer goods. This patent now gives ynvisible control over a valuable functionality improvement that other companies using electrochromic inks may wish to license and use.
Specifically, this patent covers the proprietary formulation of ynvisible's irreversible displays, which have many applications in product status and quality indication, security, and authenticity. An irreversible display allows for a visual alarm to be permanently visible after a critical event has been recorded by the smart label system (e.g. a temperature threshold has been exceeded, or the item has been tampered with). Once activated, ynvisible's irreversible displays will remain visible even after a loss of structural integrity to the underlying circuits or power source. ynvisible is very pleased to add this patent to its growing portfolio of 18 patents – 8 granted, 10 pending.
"ynvisible is solving obstacles to the mass manufacture of electrochromic devices, and this invention is a critical element in this pursuit. Receiving an EU patent for recognizing this invention is an important milestone for us," said Dr. Carlos Pinheiro, CTO.
Beyond ynvisible's immediate interests to deploy this invention in its smart label and smart films solutions, this patent also has potential applications in other fields of electrochromics as well as in other electrochemical devices, such as advanced batteries and power sources where electrolytes play an important role.
