Abstract
A driving method for an electronic paper display device is provided, belongs to the field of display technology, and can solve the problem of ghost in the existing electronic paper display device. A driving stage of the electronic paper display device includes a first shaking stage including a first sub-shaking stage; the balance stage is before the display stage. The method includes: based on a to-be-displayed image, applying first, second and third driving signals to first electrodes in macrostructures to display black, white and red, respectively; applying a voltage signal to the second electrodes, the voltage signal includes an alternating second pulse signal in which positive, zero and negative voltages are sequentially alternated in the first sub-shaking stage; the first and second pulse signals are equal in an absolute value of an active voltage and are opposite to each other in voltage polarity.
