Abstract
A control method of an e-ink screen. The e-ink screen includes a plurality of pixels, at least one pixel includes first color charged particles and second color charged particles, and the first color charged particles and the second color charged particles are same in electrical property. The control method of the e-ink screen includes: inputting a first color driving signal to pixels expected to display a first color in the e-ink screen. The first color driving signal includes a plurality of sub-signals corresponding to a plurality of driving stages. The plurality of sub-signals include a first color imaging sub-signal and a particle separation sub-signal. The particle separation sub-signal is configured to drive the first color charged particles and the second color charged particles in the at least one pixel to move, and to separate the first color charged particles from the second color charged particles.
