Abstract
A control method of an electronic ink screen includes: outputting a first color driving signal to pixel(s) expected to display a first color in the electronic ink screen. The first color driving signal includes a first dither signal and a first color first pull-up signal in adjacent periods. The first dither signal includes a first rectangular wave signal, a first electric field cancellation signal and a first constant voltage signal. The first constant voltage signal is configured to drive first color charged particles in the pixel(s) expected to display the first color to move toward a side proximate to a display surface of the electronic ink screen, and the first color first pull-up signal is configured to drive the first color charged particles in the pixel(s) expected to display the first color to move toward the side proximate to the display surface of the electronic ink screen.
