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.

Electrophoretic display and process for its manufacture

This application is directed to processes for preparing electrophoretic displays and semi-finished display panels comprising display cells prepared from the microcup and top-sealing technologies. The semi-finished display panel comprises an array of display cells sandwiched between two temporary substrate layers, between a temporary substrate layer and a conductor layer or between a temporary substrate layer and a permanent substrate layer, wherein said display cells are filled with an electrophoretic fluid and top-sealed with a polymeric sealing layer formed from a top-sealing composition which is being hardened while on top of the electrophoretic fluid.

Process for preparing a display panel

The invention is directed to methods and compositions useful for improving the performance of electrophoretic displays. The methods comprise adding a conductive filler in the form of nanoparticles and having a volume resistivity of less than about 10ohm cm into at least one electrode protecting layer of the display.

Methods and compositions for improved electrophoretic display performance

The invention is directed to novel methods and compositions useful for improving the performance of electrophoretic displays. The methods comprise adding a high absorbance dye or pigment, or conductive particles, or a conductive filler in the form of nanoparticles and having a volume resistivity of less than about 10ohm cm, or a charge transport material into an electrode protecting layer of the display.

A process for forming a patterned thin film structure on a substrate is disclosed. A pattern is printed with a material, such as a masking coating or an ink, on the substrate, the pattern being such that, in one embodiment, the desired thin film structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structures.

Electrophoretic display

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.

Segment electrophoretic displays and methods for their manufacture

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.

This invention relates to the field of electrophoretic displays. In particular, it relates to imagewise opening, filling and sealing multicolor display components and the manufacture of multicolor displays.

Process for imagewise opening and filling color display components and color displays manufactured thereof

The invention relates to electrophoretic displays comprising core-shell pigment particles having a core of low specific gravity and low refractive index and a shell of high refractive index.

Core-shell particles for electrophoretic display

The invention is directed to compositions and processes useful for the roll-to-roll manufacturing of electrophoretic displays.
