Abstract
A driving method of an electrophoretic display having at least one display particle is provided. The driving method includes the following steps. A first voltage difference is applied to a data line in a first period, in which the data line corresponds to one of the display particles. At least one particle restore period is inserted in the first period, and a second voltage difference is applied to the data line in the particle restore periods, in which the second voltage difference is different from the first voltage difference. With this method disclosed here, the maxima brightness, maxima darkness, contrast ratio, color saturation, bistability, and image updating time can be largely improved.
