Electro-optic media produced using ink jet printing
Ink jet printing can be used in the production of electro-optic displays for (a) forming a layer of a polymer-dispersed electrophoretic medium on a substrate; (b) forming a color electro-optic layer; (c) forming a color filter; and (d) printing electrodes and/or associated conductors on a layer of electro-optic material.
1. An article of manufacture comprising, in order:
(a) a light-transmissive, electrically-conductive layer;
(b) a plurality of areas of colored material ink jet printed on to the light-transmissive, electrically-conductive layer, the plurality of areas including areas of at least two different colors;
(c) a layer of an electro-optic material;
(d) a layer of a lamination adhesive; and
(e) a release sheet;
the article of manufacture further comprising at least one fiducial mark ink jet printed on the light-transmissive, electrically-conductive layer at at least one predetermined location relative to at least one area of colored material.
2. An article of manufacture, comprising, in order:
(a) a first release sheet;
(b) a first layer of a lamination adhesive;
(c) a plurality of areas of colored material ink jet printed on the previous layer, the plurality of areas of colored material including areas of at least two different colors;
(d) a layer of electro-optic material;
(e) a second layer of a lamination adhesive; and
(f) a second release sheet,
wherein layers (c) and (d) are in either order;
the article of manufacture further comprising at least one fiducial mark ink jet printed at at least one predetermined location relative to at least one area of colored material.
3. A process for forming a front plane laminate having a color filter, which process comprises:
(a) providing a light-transmissive, electrically-conductive layer;
(b) applying a layer of an electro-optic material over the light-transmissive, electrically-conductive layer;
(c) ink jet printing a plurality of areas of colored material on to the layer of electro-optic material, the plurality of areas including areas of at least two different colors;
(d) applying a layer of a lamination adhesive over the layer of colored material; and
(e) applying a release sheet over the layer of lamination adhesive;
the process further comprising ink jet printing at least one fiducial mark on the layer of electro-optic material at at least one predetermined location relative to at least one area of colored material.
