Summary:A device and method for eliminating an image border of electrophoretic electronic paper includes the following steps: S1, acquiring gray-scale driving waveform information and gray-scale position information, wherein the driving waveform information comprises a level value and a duration corresponding thereof; S2, outputting regulation waveform information based on an termination level value of a first gray scale, a level duration and a starting level value of a second gray scale, wherein the regulation waveform information comprises a level value, an embedding time and an embedding position of a waveform; and S3, modifying the gray-scale driving waveform information based on the regulation waveform information, and controlling an output of a drive electrode based on the modified gray-scale driving waveform information. By using the device and method, an impact of the fringe electric field on movement of electronic paper micro-capsules is eliminated, thus effectively reducing border ghosting.
