To address the high power consumption associated with image refresh operations in EPDs, this paper proposes a low-power driving waveform that reduces the refresh power of EPDs by lowering the system's peak power. Compared to traditional waveforms, this waveform first activates the particles before erasing them, thus reducing voltage polarity changes. Additionally, it introduces a specific duration of 0 V voltage during the activation phase based on the physical characteristics of the electrophoretic particles to reduce the voltage span. Finally, a particular duration of 0 V voltage is introduced during the erasure phase to minimize the voltage span while ensuring the stability and consistency of the reference gray scale. The experimental results demonstrate that, in standard power tests, the new driving waveform reduces the power fluctuation value by 1.33% and the energy fluctuation value by 37.24% compared to the traditional driving waveform. This reduction in refresh power also mitigates screen flicker and ghosting phenomena.
为了解决与电子纸显示器（EPD）图像刷新操作相关的高功耗问题，本文提出了一种低功耗驱动波形，通过降低系统的峰值功率来降低EPD的刷新功耗。与传统波形相比，该波形在擦除粒子之前先激活粒子，从而减少电压极性变化。此外，根据电泳粒子的物理特性，在激活阶段引入特定的0V电压持续时间，以减小电压跨度。最后，在擦除阶段引入特定的0V电压持续时间，以在确保参考灰度稳定性和一致性的同时最小化电压跨度。实验结果表明，在标准功率测试中，与传统驱动波形相比，新的驱动波形将功率波动值降低了1.33%，能量波动值降低了37.24%。刷新功耗的降低也减轻了屏幕闪烁和重影现象。
