Abstract
An electronic paper display and a driving method thereof are provided. The electronic paper display includes an electronic paper display panel, a touch panel and a processing circuit. The touch panel outputs a first touch coordinate of a current touch and a second touch coordinate of a next touch. The processing circuit executes a filter module and a line drawing module. The filter module outputs a first measured position data and a first predicted position data to the line drawing module. The line drawing module drives the electronic paper display panel to display a first predicted track. The filter module outputs a second measured position data to the line drawing module. 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.
