Large-area electro-optic light modulator or display

A method of manufacturing an electro-optic device, comprising the steps of:

• (a) providing a plurality of electro-optic units, each of said electro-optic units comprising:
• a first light-transmissive substrate having opposite inner and outer surfaces, said first light-transmissive substrate having a plurality of electrically-conductive vias extending between the inner and outer surfaces;
• a first light-transmissive electrically-conductive layer on the inner surface of the first light-transmissive substrate in electrical contact with the electrically-conductive vias of the first light-transmissive substrate;
• a second light-transmissive substrate having opposite inner and outer surfaces, said second light-transmissive substrate having a plurality of electrically-conductive vias extending between the inner and outer surfaces of the second light-transmissive substrate;
• a second light-transmissive electrically-conductive layer on the inner surface of the second light-transmissive substrate in electrical contact with the electrically-conductive vias of the second light-transmissive substrate;
• and
• an electro-optic medium layer between and in contact with the first and second light-transmissive electrically-conductive layers;
• (b) positioning the plurality of electro-optic units in a side-by-side tiled arrangement;
• and
• (c) laminating a third light-transmissive substrate covered by a third light-transmissive electrically-conductive layer on one side of the plurality of electro-optic units and a fourth light-transmissive substrate covered by a fourth light-transmissive electrically-conductive layer on an opposite side of the plurality of electro-optic units,
• wherein the third light-transmissive substrate is superposed on the outer surfaces of the first light-transmissive substrates of each of the plurality of electro-optic units, and the third light-transmissive electrically-conductive layer is disposed between the third light-transmissive substrate and the plurality of electro-optic units, said third light-transmissive electrically-conductive layer being in electrical contact with the electrically-conductive vias of the first light-transmissive substrates of each of the plurality of electro-optic units;
• wherein the fourth light-transmissive substrate is superposed on the outer surfaces of the second light-transmissive substrates of each of the plurality of electro-optic units, and the fourth light-transmissive electrically-conductive layer is disposed between the fourth light-transmissive substrate and the plurality of electro-optic units, said fourth light-transmissive electrically-conductive layer being in electrical contact with the electrically-conductive vias of the second light-transmissive substrates of each of the plurality of electro-optic units.
