Abstract
Embodiments of the present disclosure provide a method and apparatus for driving an electrophoretic display panel, and a display device. The electrophoretic display panel includes a first electrode layer, a second electrode layer, and charged particles distributed between the first electrode layer and the second electrode layer. In the method for driving an electrophoretic display panel, a direct current voltage signal is applied to the first electrode layer to cause the charged particles to move to a predetermined position. An alternating current voltage signal is applied to the first electrode layer to cause the charged particles to oscillate. A data voltage signal is applied to the first electrode layer for display. After the charged particles oscillate, the motion activity can be improved, so that the charged particles may more accurately move according to the data voltage signal, thereby improving display accuracy.
