Abstract
This invention relates to an electrophoretic display comprising a plurality of cells, each of said cells comprises: a) partition walls; b) an electrophoretic fluid filled therein; c) a polymeric sealing layer to enclose the electrophoretic fluid within the cell; and d) an interface between the electrophoretic fluid and the sealing layer.
Claims35
An electrophoretic display comprising a plurality of cells, each of said cells comprises:
- a) a partition wall surrounding the cell;
- b) an electrophoretic fluid filled therein;
- c) a sealing layer on top of said electrophoretic fluid to enclose the electrophoretic fluid within the cell;
- and
- d) an interface between the electrophoretic fluid and the sealing layer, wherein the contact point of the interface and the partition wall is at least about 0.01 μm below the top surface of the partition wall.
An electrophoretic display which comprises:
- A) two electrode plates;
- B) an array of cells, each of the cells comprises:
- a) a partition wall surrounding the cell;
- b) an electrophoretic fluid filled therein;
- c) a sealing layer on top of said electrophoretic fluid to enclose the electrophoretic fluid within the cell;
- and
- d) an interface between the electrophoretic fluid and the sealing layer, wherein the contact point of the interface and the partition wall is at least about 0.01 μm below the top surface of the partition wall.
An electrophoretic display comprising an array of display cells, wherein said display cells are filled with an electrophoretic fluid and top-sealed with a polymeric sealing layer formed from a sealing composition having a specific gravity lower than that of the electrophoretic fluid.
