1. An electro-optic display comprising:
a plurality of pixels;
a frame buffer for storing frame images, the frame buffer having a set of buffer slots arranged in a rotating configuration such that at any given time at least one buffer slot is available for storing frame images, the frame buffer configured to continuously overwrite with an image buffer write pointer configured to direct the controller to continuously overwrite the latest available memory slot;
an image buffer latest image pointer for marking on the frame buffer the location of the last complete frame image written to the frame buffer; and
a display controller for retrieving frame images from the frame buffer, wherein
the pixels of the display are partitioned into a plurality of interlaced regions, wherein
each interlaced region of the plurality of interlaced regions is updated at a time offset from each other interlaced region of the plurality of interlaced regions, wherein
each interlaced region comprises a subset of the pixels of the display, and wherein
each of the pixels within an interlaced region is non-adjacent to each other pixel within the interlaced region.
