Abstract
Chromatic systems and structures are presented that operate without external electrical supply, which enable changes in color or transparency of a substrate material, such as glass. Various configurations provide a mechanism to activate an oxidation-reduction reaction in a chromatic material, so as to change from transparent to opaque or from one color to another. These structures may be used in applications from windows for buildings and homes, camera lenses, automotive displays and windows, mobile device displays, and other applications where chromatic change is desired.
Claims20
A chromatic structure, comprising:
- a substrate layer;
- a conductive layer coupled to the substrate layer;
- a conductive dye layer coupled to the conductive layer;
- an electrolyte layer coupled to the conductive dye layer;
- and
- a first conductive contact configured to couple and decouple the electrolyte layer to and from the conductive layer,
- wherein coupling the electrolyte layer to the conductive layer through the first conductive contact reduces oxidation of the conductive dye layer, and decoupling the electrolyte layer from the conductive layer through the first conductive contact increases the oxidation of the conductive dye layer.
