Abstract:
PROBLEM TO BE SOLVED: To provide a further effective method and a composition for the method, for improving the response speed and image uniformity of an electrophoretic display and for suppressing electrical irreversible adhesion of dispersion particles or other charged particles on an electrode. SOLUTION: The method for improving electrophoretic display performance includes a step of adding a high-absorbance dye or pigment to at least one electrode protective layer in the electrophoretic display. The method for improving electrophoretic display performance also includes a step of adding conductive particles to at least one electrode protective layer in the electrophoretic display. The method for improving electrophoretic display performance further includes a step of adding a charge transport material to at least one electrode protective layer in the electrophoretic display. The adhesive composition also contains an adhesive material and the high-absorbance dye or pigment, or conductive particles or the charge transport material. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a low-cost electrophoretic display device and a driving method of addressing such an electrophoretic display. SOLUTION: The electrophoretic display device has: (a) a movable element having at least one conductive surface or chip; (b) a fixed electrode; (c) a display panel which is a display panel having a display cell charged with an electrophoretic fluid and a dielectric surface and arranged between the fixed electrode and movable element; and (d) a nonconductive fluid capable of making contact between the conductive surface or chip of the movable element and the dielectric surface of the display panel.

Abstract:
PROBLEM TO BE SOLVED: To provide a new method of manufacturing a microcup array. SOLUTION: The microcup array is manufactured by (a) coating a male mold where a pattern is preformed with a thermosetting or thermoplastic precursor composition to form a contiguous precursor layer on the male mold; (b) bringing the precursor layer into contact with a transfer sheet; (c) curing the precursor to form a cured microcapsule array; and (d) releasing the microcup array from the mold. Such a microcup array is variously used for, for example, a video display and, particularly, an electrophoresis display or liquid crystal display. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide compositions of a display cell structure (20) and electrode protecting layers for improving performance of display devices.SOLUTION: The composition comprises a polar oligomeric or polymeric material having a glass transition temperature below about 100°C, and a resultant display cell structure or electrode protecting layer has an average crosslinking density of less than about 1 crosslink point per 80 Dalton molecular weight.
