Abstract: There is provided an electrochromic fixed image display and a method for manufacturing the display. The electrochromic fixed image display for displaying a predetermined symbol comprising a stack of layers of: a colour layer which is configured to provide a resulting colour contrast to the display when comparing its on-state and off-state; a first electrochromic electrode layer arranged behind said colour layer in a viewing direction; an electronically and ionically insulating symbol defining layer, arranged behind the first electrode layer, which comprises at least one opening defining the shape the predetermined symbol; an electrolyte, arranged behind the symbol defining layer, which fills and covers the opening of said symbol defining layer; and a counter electrode layer, arranged behind the electrolyte layer, comprising an electronically conductive material, wherein the electrolyte layer is in ionic contact with the first electrode layer and the counter electrode layer.

Abstract: The invention relates to a colloidal electrolyte composition comprising a polyelectrolyte selected from one or more cationic polymers, a particulate phase forming a colloidal dispersion, and a binder system able to form a cross-linked network upon curing the electrolyte composition. Also, the invention relates to a method of preparation the colloidal electrolyte composition, to an electrochemical cell and to a method of preparation the electrochemical cell.
