Methods and compositions for improved electrophoretic display performance

摘要

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 10<4 >ohm cm, a conductive filler in the form of nanoparticles and having a volume resistivity of less than about 10<4 >ohm cm, or a charge transport material into an electrode protecting layer of the display.
