Abstract

An electronic device, including a substrate and multiple modulation units, is provided. The modulation units are disposed on the substrate. Each modulation unit includes a first electronic element, a second electronic element, a first signal line, a second signal line, and a third signal line. The first signal line provides a first voltage to the first electronic element. The second signal line provides a second voltage to the second electronic element. The third signal line provides a third voltage to the first electronic element and/or the second electronic element. The first voltage is different from the second voltage, and the third voltage is different from the first voltage and/or the second voltage.
