Abstract
A driving method of an electronic paper display apparatus, including: inputting, by a controller, a first driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required to display black, according to an image to be displayed; and inputting, by the controller, a second driving signal to a pixel electrode of a pixel driving circuit corresponding to a pixel which is required display white, according to the image to be displayed. A driving stage of the electronic paper display apparatus comprises a first homogenization stage which comprises a plurality of homogenization sub-stages. At a last homogenization sub-stage, the first and second driving signals comprise first and second driving sub-signals, respectively. Voltages of the first driving sub-signal and the second driving sub-signal have polarities opposite to polarities of the black particles and the white particles, respectively.
