Abstract

The present invention provides a driving method for a four-color electronic paper module, which is sequentially divided into a debugging operation stage, an imaging stage, and an electrical balancing stage; first, driving voltage values ​​for charged particles of four colors are preset; in the preset debugging operation stage, driving voltage values ​​of different sizes are applied within a certain time period, so that the charged particles of the four colors produce an electrophoresis phenomenon, thereby eliminating the afterimage of the initial display content on the electronic paper module; in the preset imaging stage, charged particles to be displayed are moved to the top layer of a base liquid through the electrophoresis phenomenon, so that an image is displayed on the screen of the electronic paper module; in the preset voltage balancing stage, the driving voltage values ​​are adjusted in the voltage balancing stage so that the positive and negative voltages of the four charged particles reach a balance; the driving method of the present invention has high versatility and can be applied to batches of four-color electronic paper modules, and has good display effect, high contrast and high color saturation.
