The BWR (Black-White-Red) electronic paper display has the advantage of low power consumption and offers a paper-like reading experience. However, refreshing images between black and red can easily produce ghosting images. In this article, a new driving waveform is proposed, in which classic black, white, and red particles are modeled as spheres, and the Com state is introduced as a renewal element because the motion of the sphere particles must ensure momentum conservation in the BWR EPD (Electrophoresis Display) during electronic field removal. Additionally, we adopted the concepts of gradual iteration and successive promotion in the new driving waveform based on the principles of electrophoretic particle displays and combined the momentum and inertia theorem with Stokes Law. A large number of experimental data confirmed that not only was the ghosting value optimized appreciably to below 0.5, but the actual ghosting performance has been significantly improved, especially for black and red images.
黑白红（BWR）电子纸显示器具有低功耗的优点，并提供类似纸张的阅读体验。然而，在黑色和红色之间刷新图像很容易产生重影图像。在本文中，提出了一种新的驱动波形，其中经典的黑色、白色和红色粒子被建模为球体，并且引入Com状态作为更新元素，因为在去除电场期间，球体粒子的运动必须确保黑白红电泳显示器（EPD）中的动量守恒。此外，我们基于电泳粒子显示原理，在新的驱动波形中采用了逐步迭代和连续推进的概念，并将动量和惯性定理与斯托克斯定律相结合。大量实验数据证实，不仅重影值明显优化到低于0.5，而且实际重影性能也得到了显著改善，特别是对于黑色和红色图像。
