Display method applied to electrophoretic display
An electrophoretic display includes a plurality of pixels. A display method applied to the electrophoretic display includes the following steps. Firstly, a first frame is displayed on the pixels at a first time. Next, a difference amount between the pixels at the first time and the pixels at a second time predetermined for displaying a second frame is calculated. The second time is later than the first time. Next, whether the difference amount is larger than a predetermined value is determined. Next, corresponding part of the second frame is displayed on part of the pixels corresponding to the difference amount at the second time if the difference amount is not larger than the predetermined value.
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 the pixels at a first time;
calculating a difference amount between the pixels at the first time and the pixels at a second time predetermined for displaying a second frame, wherein the second time is later than the first time;
determining whether the difference amount is larger than a predetermined value; and
displaying corresponding part of the second frame on part of the pixels corresponding to the difference amount at the second time if the difference amount is not larger than the predetermined value.
2. The display method applied to the electrophoretic display as claimed in claim 1 , wherein the predetermined value is 25 percent of the amount of the pixels.
3. The display method applied to the electrophoretic display as claimed in claim 1 , further comprising:
clearing the first frame between the first time and the second time if the difference amount is larger than the predetermined value; and
displaying the second frame on the pixels at the second time.
4. The display method applied to the electrophoretic display as claimed in claim 3 , wherein the step of clearing the first frame between the first time and the second time comprises:
displaying a first single-color frame on the pixels at a third time, wherein the third time is between the first time and the second time.
5. The display method applied to the electrophoretic display as claimed in claim 4 , wherein the step of clearing the first frame between the first time and the second time further comprises:
displaying a second single-color frame on the pixels at a fourth time, wherein the fourth time is between the third time and the second time.
6. The display method as claimed in claim 5 , wherein the first single-color frame is a black frame or a white frame, the second single-color frame is a black frame or a white frame, and the color of the first single-color frame is different from that of the second single-color frame.
7. The display method applied to the electrophoretic display as claimed in claim 1 , before the step of displaying corresponding part of the second frame on part of the pixels corresponding to the difference amount at the second time, further comprising:
clearing corresponding part of the first frame displayed on part of the pixels corresponding to the difference amount between the first time and the second time.
8. The display method applied to the electrophoretic display as claimed in claim 7 , wherein the step of clearing corresponding part of the first frame displayed on part of the pixels corresponding to the difference amount between the first time and the second time comprises:
displaying a first single-color image on part of the pixels corresponding to the difference amount at a third time, wherein the third time is between the first time and the second time.
9. The display method applied to the electrophoretic display as claimed in claim 8 , wherein the step of clearing corresponding part of the first frame displayed on part of the pixels corresponding to the difference amount between the first time and the second time further comprises:
displaying a second single-color image on part of the pixels corresponding to the difference amount at a fourth time, wherein the fourth time is between the third time and the second time.
10. The display method applied to the electrophoretic display as claimed in claim 9 , wherein the first single-color image is a black image or a white image, the second single-color image is a black image or a white image, and the color of the first single-color image is different from that of the second single-color image.
