  • Publication number: 20100085284
    Abstract: A method of driving an electro-optic display includes the following steps. First, a first frame is displayed on pixels at a first time. Next, data of a second frame predetermined to be displayed on the pixels at a second time later than the first time is determined. Next, an eliminating frame showing a first extreme gray level or a second extreme gray level is displayed on the pixels at a third time. Afterwards, a medium frame is displayed on the pixels at a fourth time later than the third time. The third and fourth times are between the first and second times. The gray level shown by each pixel at the fourth time is close to the gray level predetermined to be shown by the same pixel at the second time. Thereafter, the second frame is displayed on the pixels at the second time.

  • Publication number: 20100073277
    Abstract: 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.

  • Patent number: 7545559
    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.
