Abstract
The disclosure provides a driving method. The driving method includes following steps. During a normal scan period, a part of drivers provide first control signals generated according to a first clock frequency to target gate lines included in a part of gate line groups. During a high scanning period, the part of drivers provide second control signals generated according to a second clock frequency to residual gate lines included in the part of gate line groups.
