Review on Image Preprocessing and Driving Waveform Design for Electrophoretic Displays

ABSTRACT E‐paper, as an emerging eco‐friendly display technology, has gained significant attention due to its paper‐like visual effect and low power consumption characteristics. The concept was first proposed in the 1970s, and after years of development, it has evolved from the initial black‐and‐white image display technology to full‐color video display. Electrophoretic display shows images by controlling charged particles within microcapsules using an electric field, offering high reflectivity and contrast, and is widely used in various fields such as e‐readers, mobile phones, automobiles, wearable devices, and more. The e‐paper display system mainly consists of the e‐paper screen, control circuits, image processing algorithms, and electronic ink driving waveforms. The review introduces the research history and applications of electrophoretic display, e‐paper image processing algorithms, and driving waveforms. It also summarizes the current challenges and development trends in the field of e‐paper.
