Abstract
An electronic device is provided. The electronic device includes a substrate, a panel, an optical modulation layer, and a control unit. The panel includes a first region, a second region, and a third region between the first region and the second region. The optical modulation layer is disposed corresponding to the panel. The control unit is electrically connected to the panel. The control unit inputs a bright region voltage to the first region and the second region, and inputs a dark region voltage to the third region during a plurality of operation periods. The bright region voltage differs from the dark region voltage during any of the operation periods.
