Abstract
Improved methods for driving color electro-optic displays, such as electrophoretic displays with multi-particle electrophoretic media. When driving between a first image having a high color depth (i.e., greater than 64 distinct colors) and a second image having a high color depth, the data processing load can be reduced by mapping the set of colors in the first image to a reduced color set. In a preferred embodiment, the electro-optic medium is an electrophoretic medium that includes a white particle and cyan, yellow, and magenta subtractive primary-colored particles. Images with high color depth look less grainy and are more appealing to consumers.
