The disclosure is directed toward driving methods and a driving circuit which are particularly suitable for bi-stable displays. In certain embodiments, methods provide the fastest and most pleasing appearance to the desired image while maintaining the optimal image quality over the life expectancy of an electrophoretic display device.

Driving methods and circuit for bi-stable displays

The present invention is directed to a display device which comprises two layers of insulating substrate, at least the substrate on the viewing side is transparent, an array of display cells sandwiched between the two layers of substrate, a writing means, and optionally an erasing means to magnetically or electrically erase the image. The display cells are filled with a dispersion of magnetic particles which may be charged or non-charged. The display of the invention eliminates the use of the transparent conductor film, such as ITO, on the viewing side. Therefore, the displays of this invention are more cost effective, more flexible and durable and capable of higher image contrast ratio and higher reflectance in the Dmin area.

Magnetophoretic and electromagnetophoretic displays

The present invention is directed to an electrophoretic display fluid, in particular, pigment particles dispersed in a solvent or solvent mixture, and methods for their preparation. The pigment particles generated, according to the present invention, are stable in solvent under an electric field and can improve the performance of an electrophoretic display.

Silane-containing pigment particles for electrophoretic display

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 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.

The disclosure relates to driving methods for bistable displays, in particular, driving methods comprising interleaving driving waveforms.

Driving methods for bistable displays

The invention is directed to compositions of display cell structure and electrode protecting layers for improving the performance of display devices. The composition comprises a polar oligomeric or polymeric material having a glass transition temperature below about 100&#xb0; C., and the resulting display cells or electrode protecting layer have an average crosslinking density of below about 1 crosslink point per 80 Dalton molecular weight.

Display cell structure and electrode protecting layer compositions

The invention relates to a novel sealing composition for the manufacture of an electrophoretic or liquid crystal display, and a sealing process using the composition. The composition allows electrophoretic or liquid crystal cells to be seamlessly sealed and the sealing layer free of any defects.

Composition and process for the sealing of microcups in roll-to-roll display manufacturing

The present invention is directed to a novel reactive protective colloid system suitable for stabilizing an electrophoretic display in which a halogenated solvent, particularly a fluorinated, more particularly a perfluorinated, solvent, or a mixture thereof, is used as the dielectric solvent.

Functionalized halogenated polymers for microencapsulation

The present invention is directed to an electrophoretic display fluid, in particular, pigment particles dispersed in a solvent or solvent mixture, and methods for their preparation. The pigment particles generated, according to the present invention, are stable in solvent under an electric field, have desired charge and charge density on the particle surface.

Pigment particles for electrophoretic display

Driving methods are described for display devices which have one or more dielectric layers in the path of an electric field driving the display. In an embodiment, image uniformity is improved by periodically refreshing, using an intermediate color state, pixels that remain in one color state before and after a change in displaying a first image and a second image, and by applying driving signals using voltage levels and durations that maintain a global DC balance in the display at near zero to avoid contrast reduction and image artifacts in the image.

This invention relates to improved electrophoretic dispersions and a method for improving the performance of an electrophoretic display. The invention also relates to a method of inducing or enhancing the threshold voltage of an electrophoretic dispersion.

Electrophoretic dispersions
