Methods for driving electro-optic displays

An electro-optic display comprising:

• an electrophoretic medium comprising charged pigment particles;
• a plurality of display pixels for driving the charged pigment particles between optical states, the plurality of display pixels arranged in a matrix comprising a two-dimensional array of rows and columns of display pixels;
• a touch-enabled input device having a touch panel;
• and
• a controller operatively coupled to the plurality of display pixels and the touch-enabled input device,
• wherein the controller is configured to:
• update the plurality of display pixels with a first image comprising image data;
• receive, from the touch-enabled input device, a user input comprising one or more parameters;
• generate a second image based on at least one parameter of the user input, wherein the second image comprises a subset of the image data of the first image but is enlarged to have dimensions equal to the first image;
• separate the second image into a plurality of portions of the second image;
• update the plurality of display pixels with a first portion of the plurality of portions of the second image;
• and
• update the plurality of display pixels with a second portion of the plurality of portions of the second image, wherein the second portion does not include the content of the first portion.
