The present invention relates to novel patterned embossing and patterned filling methods. Both methods are simple, reliable and cost effective ways for manufacturing the segment of signage electrophoretic displays. The displays prepared by the present invention requires only one patterned electrode layer. The undesired visible line traces are eliminated and the manufacture of the present displays does not involve the costly precision registration step used in the previously known assembly processes dealing with two patterned electrodes. Moreover, the electrophoretic fluid is present only in the patterned and switchable area of the display. This not only significantly reduces the material cost, but also improves the overall display quality by reducing defects and non-uniformity.
A display comprising active electrophoretic cells in a patterned area wherein said cells are filled with an electrophoretic fluid which comprises pigment particles dispersed in a solvent or solvent mixture.
A display comprising:
An electrophoretic display comprising:
An electromagnetophoretic display comprising:
A process for the manufacture of an electrophoretic display or an electromagnetophoretic display, which comprises embossing selectively in a patterned area to form the microcups in said patterned area.
