ABSTRACT:
Electrochromic material for an electro-optic display includes an oxide of at least one transition metal having a structure related to a hexagonal tungsten bronze structure whereby ions of an electro-active material readily diffuse through the lattice structure. In a display the electrochromic material is positioned between two electrodes with an electrolyte between and contacting the electrochromic material and one electrode which comprises the electro-active material.
