Reflective display which is also called electronic paper display without backlight, using ambient light to read and having a similar “traditional paper” viewing experience, may become one of the mainstream display technologies. Electrophoretic display (EPD), as a new reflective display technology, has attracted much attention because of its low cost, low weight, low power consumption and high reliability. EPD is based on the movement of charged particles through oppositely charged electrodes in dielectric fluid. Some parameters of electrophoretic particles, such as particle size, particle size distribution and surface charge etc.‍, have an important impact on image quality, image control and image response time. Therefore, the researchers have done a lot of work on the preparation, surface morphology modification of electrophoretic particles and preparation of microcapsules. This paper will review the progress in these fields of EPD.
