In a driving circuit for outputting a driving voltage to an optically switchable panel, the driving voltage is an alternating current (AC) driving voltage. In an operating state of the driving circuit, a driving voltage is supplied to the optically switchable panel. In the operating state, the driving circuit is configured to change the driving frequency of the AC driving voltage without affecting the optical state of the optically switchable panel.
在用于将驱动电压输出到光学可切换面板的驱动电路中,驱动电压为交流(AC)驱动电压。在所述驱动电路的操作状态中,将驱动电压供应到光学可切换面板。在所述操作状态中,驱动电路配置成改变交流驱动电压的驱动频率而不影响光学可切换面板的光学状态。
