An electrochromic device in which specific channel direction for the conduction of ions is implemented. As a result ionic crosstalk between display pixels is greatly reduced and unwanted transient coloration effects are minimized. Further, specific gel, polymer, or ionic liquid solutions can greatly eliminate the corrosive effects associated with the use of electrolyte salt solutions.

Electrochromic device employing gel or solid polymers having specific channel direction for the conduction of ions

The invention concerns discrete electrochromic particles comprising conducting, semiconducting or insulating nanoparticles having one or more electrochromic compounds adsorbed on the surface thereof. These particles may be deposited on an electrode in a single process step at a relatively low temperature, thereby allowing the use of heat-sensitive materials such as plastics as flexible substrates for the electrode.
