Abstract:
An electrophoretic medium may be incorporated into an electrophoretic display that includes a dispersion containing a non-polar fluid, a plurality of first charged colored particles, polyisobutylene, and an additive selected from co-polymers of vinyl aromatics and at least one hydrocarbon having 2 to 5 carbons and at least one double bond. The co-polymer and the ratio of the co-polymer to polyisobutylene is selected, such that bistability performance is maintained while improving the color state performance of the display.
