  • Method for updating display image of electrophoretic display panel and electrophoretic display apparatus using the same
    Patent number: 8674931
    Abstract: A method for updating display image of an electrophoretic display panel and an electrophoretic display apparatus using the same are provided. In the aforementioned method, the gate lines of the electrophoretic display panel are divided into a first group and a second group. The display data related to pixels coupled to the gate lines of the first group need not to be updated. Furthermore, the display data related to at least one of the pixels coupled to the gate lines of the second group need to be updated. The first type gate pulses are provided to the gate lines of the first group respectively, and second type gate pulses are provided to the gate lines of the second group respectively. The second type gate pulse has a predetermined pulse width. The pulse width of the first type gate pulse is shorter than the predetermined pulse width.
