摘要:
The present invention is directed to methods for the preparation of pigment particles suitable for use in an electrophoretic dispersion, particularly an electrophoretic dispersion in a fluorinated solvent. The method comprises: a) treating pigment particles to incorporate reactive groups onto the surface of the pigment particles; and b) reacting said reactive group with a functional group in a fluorinated monomer, oligomer or polymer to form a polymer layer over the surface of the pigment particles.
摘要:
The present invention is directed to an electrophoretic dispersion comprising pigment particles dispersed in a solvent or solvent mixture, wherein said pigment particles comprises at least one polymer chain comprising a terminal thiocarbonylthio group, attached to the particle surface. The invention also relates to pigment particles suitable for use in an electrophoretic dispersion and methods for their preparation through a RAFT polymerization technique.

The present invention is directed to a display fluid comprising charged composite pigment particles dispersed in a solvent. The composite pigment particles have a density which matches to the density of the solvent in which they are dispersed. A display fluid comprising the composite pigment particles provides improved display performance.

摘要:
The present invention is directed to an electrophoretic dispersion comprising charged pigment particles dispersed in a solvent or solvent mixture, wherein the pigment particles have an average aggregation size more than 2 times their primary size. The electrophoretic dispersion of the present invention is capable of improving image bistability through adjusting the aggregation size of the charged pigment particles.

The present invention is directed to an electrophoretic fluid comprising uncharged or lightly charged neutral buoyancy particles. The resulting fluid can improve not only image stability but also contrast ratio of a display device, without significantly affecting the switching speed. The present invention is also directed to an electrophoretic display comprising display cells filled with the electrophoretic fluid.
