ABSTRACT:
A display method applied to an electrophoretic display having pixels includes steps as follows. Firstly, a first frame is displayed on the pixels at a first time. Then the difference between the pixels at the first time and those at a second time predetermined for displaying a second frame is determined and part of the pixels corresponding to the difference are divided into a first pixel group (pg) and a second pg. The first pg shows a first single-color at the first time and a second single-color at the second time and the color shown by the second pg is opposite to that shown by the first pixel group. Next, a medium image is displayed on the first pg at a third time between the first and the second times and shows the second single-color. Afterwards, corresponding part of the second frame is displayed on the second pg at the second time.
