Abstract
The application provides a method for driving a color electronic paper, including: according to an image to be displayed, applying a first driving signal to a first electrode on a to-display-white microcapsule and a second driving signal to a first electrode on a to-display-black microcapsule. The first driving signal includes: a first sub-driving signal applied to the first electrode on the to-display-white microcapsule in display phase; and the first sub-driving signal is configured to drive a white particle in the to-display-white microcapsule to be closer to a display side than a black particle and a colored particle. The second driving signal comprises: a second sub-driving signal applied to the first electrode on the to-display-black microcapsule in display phase, and the second sub-driving signal is configured to drive the black particle in the to-display-black microcapsule to be closer to the display side than the white particle and the colored particle.
