Abstract
An embodiment of the invention provides a driving method for a display unit, wherein the display unit includes a first electrode, and a second electrode disposed opposite to the first electrode, wherein the first electrode is separated from the second electrode by a distance, and a first particle with a polarity is distributed between the first electrode and the second electrode. The driving method includes the steps of: casting a first voltage difference between the first electrode and the second electrode to make the first particle move toward the second electrode; stopping casting of the first voltage difference; and casting a second voltage difference between the first electrode and the second electrode to apply an opposite force to the first particle, wherein the polarity of the second voltage difference is different from that of the first voltage difference.
