A display () primarily intended for use on an external surface of a building comprises a weatherproof housing (); a bistable electro-optic medium () enclosed within and visible through the housing; an electrode () enclosed within the weatherproof housing and arranged to drive the electro-optic medium; a power source () enclosed within the weatherproof housing; data receiving means () enclosed within the weatherproof housing and arranged to receive data wirelessly from a source outside the weatherproof housing; and display drive means () arranged to receive data from the data receiving means and power from the power source, and to control the potential of the electrode.

Displays intended for use in architectural applications

Polymer formulations including urethane acrylates, adhesion promoters, and conductive monomers. By selecting suitable conductive monomers, it is possible to achieve formulations having a volume resistivity from 10to 10Ohm&#xb7;cm after being conditioned for one week at 25&#xb0; C. and 50% relative humidity. Such formulations are suitable for incorporation into electro-optic materials, such as electro-optic displays or variable transmission films, e.g., for architectural applications. In other embodiments, the formulations additionally include metal oxide nanoparticles to alter the refractive index and/or conductivity.

In other embodiments, the formulations additionally include metal oxide nanoparticles to alter the refractive index and/or conductivity. The addition of certain metal nanoparticles additionally facilitates non-destructive measurement of layer thickness using X-ray fluorescence spectroscopy.
