Abstract: A driving method for an electrowetting panel is provided. The electrowetting panel includes M driving electrodes sequentially arranged along a first direction. The driving method includes providing electrical signals to the M driving electrodes, such that a droplet is acquired from a solution reservoir by the 1st driving electrode, and is driven to move by the M driving electrodes. During a droplet moving period, a pulse width of a driving signal of an mth driving electrode is Wm = ∑ i = 1 m W i , a pulse width of a non-driving signal between an ath driving signal and an (a+1)th driving signal of the mth driving electrode is Zma = ∑ i = m + 1 m + a W i . M, m, and a are positive integers, 1≤m≤M, and M≥3. The end time of the 1st driving signal of the mth driving electrode and the end time of the mth driving signal of the 1st driving electrode are the same.
