摘要:
The invention provides a first process for addressing an electro-optic material having first and second display states differing in at least one optical characteristic and being capable of being changed from its first to its second display state by application of an electric field to the material, the process comprising applying an electrically charged fluid to a portion of at least one surface of the material, thereby changing the display state of a portion of the material. The invention also provides a second process for addressing an electro-optic material, this process comprising contacting the electro-optic material with a non-conductive brush means wet with a conductive liquid while applying a potential difference between the brush means and the electro-optic material.

The invention provides an electrophoretic medium comprising at least two types of particles having substantially the same electrophoretic mobility but differing colors. The invention also provides article of manufacture comprising a layer of a solid electro-optic medium, a first adhesive layer on one surface of the electro-optic medium, a release sheet covering the first adhesive layer, and a second adhesive layer on an opposed second surface of the electro-optic medium.

摘要:
An electro-optic display comprises a layer (130) of a solid electro-optic material, at least one electrode disposed adjacent the layer (130) of electro-optic material, and a layer (180) of a lamination adhesive interposed between the layer (130) of electro-optic material and the electrode, the lamination adhesive (180) having a higher electrical conductivity in a direction perpendicular to the layer of lamination adhesive than in the plane of the layer.
