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.

Method and for driving electronic paper display device, device, and readable medium

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.

Control method of e-ink screen, and display control apparatus

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.
