Electronic paper display and driving method thereof

An electronic paper display, comprising:

• an electronic paper display panel;
• a touch panel, integrated with the electronic paper display panel, and configured to output a first touch coordinate of a current touch and a second touch coordinate of a next touch;
• and
• a processing circuit, coupled to the electronic paper display panel and the touch panel, and configured to execute a filter module and a line drawing module,
• wherein the filter module outputs a first measured position data and a first predicted position data to the line drawing module according to the first touch coordinate, and the line drawing module drives the electronic paper display panel to display a first predicted track by a connection line between a first track display coordinate corresponding to the first measured position data and a first predicted display coordinate corresponding to the first predicted position data,
• wherein the filter module outputs a second measured position data to the line drawing module according to the second touch coordinate, and the line drawing module determines whether a second track display coordinate corresponding to the second measured position data is equal to the first predicted display coordinate to correct the first predicted track,
• wherein the line drawing module generates a pre-drawing data according to the first predicted position data, and a first drawing data according to the first measured position data and the second measured position data,
• wherein the line drawing module compares a plurality of predicted coordinates of the pre-drawing data and a plurality of first coordinates of the first drawing data to generate a track correction data for correcting the first predicted track.
