Patterned electro-optic displays and processes for the production thereof

摘要

An electro-optic medium comprises at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli. The medium allows for development of differing colors in differing areas of the medium, thus allowing formation of intrinsic color within differing areas of a single layer of the same electro-optic medium. In an electrophoretic medium, the colors may be developed within the electrophoretic particles or within the fluid in which the particles are dispersed.

主权项

1. An electro-optic medium comprising at least one leuco dye such that the electro-optic medium can develop at least two differing colors upon exposure to two or more differing stimuli, the electro-optic medium further comprising an electrophoretic material comprising a plurality of electrically charged particles disposed in a fluid and capable of moving through the fluid under the influence of an electric field.
