Abstract
A method of manufacturing a coating for an e-paper assembly includes forming a coating layer from conductive particles dispersed within an insulative matrix. A field is applied to cause the conductive particles to align in generally parallel, spaced apart elongate patterns that are generally perpendicular to a plane through which the coating layer extends. At ambient temperatures and without applied pressure, the coating layer is cured via radiation energy while maintaining the applied field.

A method of manufacturing a coating for an e-paper structure, the method comprising:
- forming a first layer from a coating in which conductive particles are dispersed within a substantially insulative matrix, wherein forming the first layer includes depositing the coating as the first layer onto a first side of an e-paper substrate;
- applying a field to cause the conductive particles to align in parallel, spaced apart elongate patterns that are perpendicular to a plane through which the first layer extends;
- and
- curing, at ambient temperatures and without applied pressure, the first layer via radiation energy while maintaining the applied field to produce the coating with at least a non-adhesive outer surface.
A method of manufacturing an e-paper structure comprising:
- providing an e-paper structure including an electrically passive, imageable layer having a first side and an opposite second side onto which is fixed a counter electrode layer;
- depositing a coating onto the first side of the imageable layer, the coating including conductive particles dispersed within a conductive-resistant medium which is non-adhesive upon curing;
- applying a field to cause the conductive particles within the coating to align in parallel, spaced apart elongate patterns that are perpendicular to a plane through which the imageable layer extends;
- and
- curing, at ambient temperatures and without applied pressure, the coating via radiation energy while maintaining the applied field.
A method of manufacturing an e-paper structure comprising:
- providing an e-paper structure including a charge-responsive layer having a first side and an opposite second side onto which is fixed a counter electrode layer;
- depositing a coating as an outer protective layer onto the first side of the charge-responsive layer, the coating including conductive particles dispersed within a cohesive, insulative matrix which is non-adhesive upon curing, wherein the conductive particles have a first conductivity at least two orders of magnitude greater than a second conductivity of the insulative matrix and wherein the conductive particles include a magnetically-responsive material;
- applying a field to cause the conductive particles within the outer protective layer to align in parallel elongate patterns to extend in a first orientation perpendicular to a plane through which the charge-responsive layer extends;
- and
- curing, at ambient temperatures and without applied pressure, the outer protective layer via radiation energy while maintaining the applied field.
