The invention provides a driving method for a display panel. According to the driving method for the display panel of the present invention, first red multiplexed signals, first green multiplexed signals, first blue multiplexed signals, second red multiplexed signals, second green multiplexed signals, and second blue multiplexed signals are properly set, so that the charging time points of sub-pixels corresponding to switching elements controlled by the first red multiplexed signals, the first green multiplexed signals, and the first blue multiplexed signals in the (2i-1)-th multiplexing period are earlier than the charging time points of sub-pixels corresponding to switching elements controlled by the second red multiplexed signals, the second green multiplexed signals, and the second blue multiplexed signals, and the charging time points of the sub-pixels corresponding to the switching elements controlled by the first red multiplexed signals, the first green multiplexed signals, andthe first blue multiplexed signals in the 2i-th multiplexing period are later than the charging time points of the sub-pixels corresponding to the switching elements controlled by the second red multiplexed signals, the second green multiplexed signals, and the second blue multiplexed signals, and therefore, the fringes of pictures displayed by the display panel can be eliminated, and display quality can be improved.

本发明提供一种显示面板的驱动方法。本发明的显示面板的驱动方法通过对第一红色、第一绿色、第一蓝色、第二红色、第二绿色及第二蓝色复用信号进行设置,使得在第2i‑1个复用周期中受第一红色、第一绿色及第一蓝色复用信号控制的开关元件对应的子像素的充电时刻早于受第二红色、第二绿色及第二蓝色复用信号控制的开关元件所对应的子像素的充电时刻,而在第2i个复用周期中受第一红色、第一绿色及第一蓝色复用信号控制的开关元件对应的子像素的充电时刻晚于受第二红色、第二绿色及第二蓝色复用信号控制的开关元件所对应的子像素的充电时刻,从而消除显示面板显示的画面的条纹感,提升显示品质。
