Abstract: A driving method is provided. The driving method includes providing first driving information to a first driving element to drive a first movable portion to move relative a fixed portion in a first direction. The first driving information has a total duration, and includes positive driving signal, negative driving signal, and middle driving signal. The positive driving signal has a positive duration, the negative driving signal has a negative duration, and the middle driving signal has a middle duration. The positive duration, the negative duration, and the middle duration add up as the total duration. A ratio of the positive duration to the total duration is between 0.1 and 0.15.
