1. A method for driving an electro-optic display having a plurality of display pixels and controlled by a display controller, the display controller associated with a host for providing operational instructions to the display controller, the method comprising:
updating the display with a first image;
updating the display with a second image subsequent to the first image;
updating the display with a third image subsequent to the second image;
processing image data associated with the first image and the second image in concurrency with the updating of the third image to identify display pixels with edge artifacts and generate image data associated with the identified pixels;
storing the generated image data associated with the identified pixels at a memory location;
selecting a waveform depending on the generated image data; and
initiating the waveform to clear the edge artifacts in response to a request initiated by the host.
