Electrophoretic display device and method for manufacturing same
View Patent ↗A method of manufacturing is disclosed for an electrophoretic display apparatus that includes an array substrate and an electrophoretic film laminated to the array substrate. A thermally activated adhesive is used to adhesively attach the electrophoretic film to the array substrate. The electrophoretic film is first aligned to and flattened against the array substrate and then a substantially stronger than original adhesion property of the adhesive is activated by annealing at a high temperature that is substantially greater than room temperature. Rework prior to annealing is therefore possible when alignment errors occur between the electrophoretic film and the array substrate.
1. An electrophoretic display comprising:
an array panel including a thin film transistor connected to a gate wire and a source wire, and a pixel electrode connected to the thin film transistor;
an electrophoretic film including an electrophoretic layer and a common electrode; and
an adhesive positioned between the electrophoretic film and the array panel,
wherein the adhesive comprises:
an epoxy phenol resin made of the epoxy resin and the phenol resin at an inclusion by weight value of greater than 0% and under about 50% by weight composition ratio,
a silicon filler at an inclusion by weight value of greater than 0% and under about 15% by weight composition ratio, and
an acrylic rubber at an inclusion by weight value of greater than about 40% and under about 80% by weight composition ratio.
2. The electrophoretic display of claim 1 , wherein the adhesive is included in an adhesive layer positioned between a surface of the electrophoretic film and a surface the array panel.
3. The electrophoretic display of claim 1 , wherein the phenol resin includes bisphenol A.
4. The electrophoretic display of claim 1 , wherein the adhesive does not exhibit substantial adhesion to at least one of the electrophoretic film and the array panel unless the adhesive is subjected to a curing temperature substantially greater than a room temperature.
5. The electrophoretic display of claim 4 , wherein the room temperature is greater than or equal to 50° C.
