Abstract
This invention relates to an electrophoretic display comprising cells which are filled with charged particles dispersed in a solvent and are individually sealed with a polymeric sealing layer.
Claims37
An electrophoretic display comprising a plurality of cells, each cell:
- a) being defined by side walls, the side walls having a side surface and a top surface;
- b) being filled with an electrophoretic fluid comprising charged particles dispersed in a dielectric solvent or solvent mixture, with the top surface of the side walls being at least about 0.01μ above the top surface of the electrophoretic fluid;
- and
- c) being individually sealed with a polymeric sealing layer:
- i) which is in intimate contact with and forms a contiguous film on the fluid;
- ii) which is in intimate contact with the side surface of the side walls of the cell above the fluid;
- and
- iii) which is in intimate contact with the top surface of the side walls of the cell.
