Abstract
Encapsulated liquid crystal is deposited onto an electrode by providing a substrate having an electrode pattern thereon; placing the substrate and the electrode pattern in contact with an electrodeposition medium comprising a liquid crystal composition, a containment medium or precursor therefor, and optionally a carrier medium; and depositing encapsulated liquid crystal material comprising the liquid crystal composition dispersed in the containment medium onto the electrode pattern or selected portions thereof by applying a voltage to the electrode pattern or selected portions thereof. The coated substrate-electrode combination can then be made into displays, privacy screens, signs, architectural partitions, and the like.
Claims16
A method of applying encapsulated liquid crystal material to an electrode material, comprising the steps of:
- providing a substrate having an electrode pattern thereon;
- placing the substrate and the electrode pattern in contact with an electrodeposition medium comprising a liquid crystal composition, a containment medium or precursor therefor, and optionally a carrier medium;
- and
- depositing encapsulated liquid crystal material comprising discrete volumes of the liquid crystal composition encapsulated, dispersed, embedded, or otherwise contained in the containment medium onto the electrode pattern or selected portions thereof by applying a voltage to the electrode pattern or selected portions thereof;
- the encapsulated liquid crystal structure being capable of switching from a highly light scattering state to a highly non-scattering and substantially transparent state upon the application of a sufficient electric field.
