Abstract
This invention relates to an electrophoretic display comprising cells of well-defined shape, size and aspect ratio which cells are filled with charged pigment particles dispersed in a solvent, and novel processes for its manufacture.
Claims44
An array of cells for an electrophoretic display wherein each of said cells comprises:
- (a) surrounding partition walls,
- (b) an electrophoretic composition filled therein, and
- (c) a polymeric sealing layer which is formed from a sealing composition having a specific gravity lower than that of said electrophoretic composition and sealingly adheres to the surface of the partition walls to enclose said electrophoretic composition within each cell.
An electrophoretic display comprising:
- a) one top electrode plate and one bottom electrode plate, at least one of which is transparent;
- and
- b) a plurality of cells enclosed between the two electrodes, each of said cells comprises:
- (i) surrounding partition walls,
- (ii) an electrophoretic composition filled therein, and
- (iii) a polymeric sealing layer which is formed from a sealing composition having a specific gravity lower than that of said electrophoretic composition and sealingly adheres to the surface of the partition walls to enclose said electrophoretic composition within each cell.
