Abstract
A updating method of images in electronic paper panel includes: divide the screen and image into (N*N) areas and build indexes for them; compare the present image on the display screen with the next image and compute the different areas; according to the computing result, find the uppermost, undermost, leftmost and rightmost different areas and compute the area of the smallest rectangle which includes the different areas; compare the result with the configured threshold and according to this compared result, set up the updating method to display the image. This method effectively reduces the data of updating images and save the power of the electronic paper, especially the power of the electronic paper panel. It can also improve the response time of the electronic paper panel. At the same time, it is easy to be ported to other advanced embedded operating systems. Thus, it could provide an effective method for the products related to the electronic paper.
