The present invention provides improved driving methods for four particle electrophoretic displays that improves the performance of such displays when they are deployed in low temperature environments and the displays are required to be updated when positioned vertically (i.e., the driving electric fields are substantially perpendicular to the direction of Earth's gravity). Methods are provided for displaying each of the colors at each pixel, as desired, with minimal interference (contamination) from the other particles.
