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.

Claims (7)

1. A display method applied to an electrophoretic display, wherein the electrophoretic display has a plurality of pixels, the method comprising:

displaying a first frame on all the pixels at a first time;

determining a difference between all the pixels at the first time and all the pixels at a second time predetermined for displaying a second frame and dividing part of the pixels corresponding to the difference into a first pixel group and a second pixel group, wherein the second time is later than the first time, the first pixel group shows a first single-color at the first time and shows a second single-color at the second time, and the second pixel group shows the second single-color at the first time and shows the first single-color at the second time;

displaying a medium image on the first pixel group at a third time, wherein the third time is between the first time and the second time, and the medium image shows the second single-color; and

displaying corresponding part of the second frame on the second pixel group at the second time.

2. The display method applied to the electrophoretic display as claimed in claim 1 , wherein the first single-color is black, and the second single-color is white.

3. The display method applied to the electrophoretic display as claimed in claim 1 , wherein the first single-color is white, and the second single-color is black.
