Claim:
A method of driving an electrophoretic display, wherein the electrophoretic display has a plurality of pixels, each of the pixels is adapted to displaying a plurality of gray levels, and a group composed of the gray levels includes a deepest gray level, a plurality of intermediate gray levels and a lightest gray level, the method of driving the electrophoretic display comprising: displaying a first frame on the pixels at a first time; determining data of a second frame, wherein the second frame is predetermined to be displayed on the pixels at a second time, and the second time is later than the first time; displaying an eliminating frame at a third time, wherein the third time is between the first time and the second time, the eliminating frame is the next one frame posterior to the first frame, and the eliminating frame shows the deepest gray level or the lightest gray level on all the pixels; displaying a first medium frame at a fourth time, wherein the fourth time is between the third time and the second time, the first medium frame is the preceding one frame prior to the second frame, and the gray level shown by each of the pixels at the fourth time is close to the gray level predetermined to be shown by the same pixel at the second time; and displaying the second frame on the pixels at the second time, thereby a ghost image of the first frame appears at the second frame is avoided and uncomfortable feeling during switching from the first frame to the second frame is reduced.
