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

This invention relates to a liquid crystal display with improved contrast ratio, switching performance, reflectivity at the Dmin state and structural integrity, and methods for its manufacture. The liquid crystal display of the present invention comprises microcups as display cells, wherein the microcups are formed from a microcup composition and filled with a liquid crystal composition.

Transmissive or reflective liquid crystal display

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.

The invention is directed to a method for improving the performance of electrophoretic displays by modifying the electrical properties of the display cells.

Modification of electrical properties of display cells for improving electrophoretic display performance

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.

This invention relates to a liquid crystal display with improved contrast ratio, switching performance, reflectivity at the Dmin state and structural integrity, and methods for its manufacture.

Transmissive or reflective liquid crystal display and novel process for its manufacture

This invention relates to an electrophoretic display with improved contrast ratio, switching performance, reflectivity at the Dmin state and structural integrity, and methods for its manufacture.

Electrophoretic display and novel process for its manufacture

The present invention is directed to a process which comprises removing and stripping off part of the display panel in order to expose and connect the conductor lines on an electrode plate to a driver circuitry. More specifically the process involves (1) preparing a display panel having filled display cells sandwiched between a first and a second substrate layers, preferably by a roll-to-roll process; (2) removing part of a first substrate by asymmetrical cutting by, for example, a die, diamond, knife or laser cutting method to expose the layers underneath (which may include adhesive layer, primer layer, display cell layer and in the case of a display prepared by the microcup technology, the microcup layer and the sealing layer); and (3) stripping off the exposed layers by a stripping solvent or solution. After stripping, the conductor lines on the second substrate are exposed and ready for connection to the driver circuitry.
