Abstract
A multi-layer film, useful as a front sub-assembly in electro-optic displays, comprises, in this order: a light-transmissive electrically-conductive layer (114); a light-transmissive first protective layer (112); a light-transmissive moisture barrier layer (108); and a light-transmissive second protective layer (106). This multi-layer film can be used in forming an electro-optic display by the processes described in U.S. Pat. No. 6,982,179 or Patent Publication No. 2007/0109219.
Claims12
A multi-layer film useful as a front sub-assembly in electro-optic displays, the multi-layer film comprising, in this order:
- a light-transmissive electrically-conductive layer;
- a light-transmissive, polymeric first protective layer;
- an adhesive layer;
- a light-transmissive moisture barrier layer adhered to the first protective layer by means of the adhesive layer;
- and
- a light-transmissive, polymeric second protective layer.
A process for assembling an electro-optic display comprising:
- providing a multi-layer film which itself comprises, in this order:
- a light-transmissive electrically-conductive layer;
- a light-transmissive, polymeric first protective layer;
- an adhesive layer;
- a light-transmissive moisture barrier layer adhered to the first protective layer by means of the adhesive layer;
- and
- a light-transmissive, polymeric second protective layer;
- providing a double release film comprising a layer of an electro-optic medium sandwiched between first and second adhesive layers;
- providing a backplane comprising at least one pixel electrode,
- laminating the double release film to the multi-layer film with the first adhesive layer contacting the electrically-conductive layer, thus securing the double release film to the multi-layer film;
- and
- laminating the double release film to the backplane with the second adhesive layer contacting the backplane, thus securing the double release film to the backplane,
- the two laminations being done in either order.
