Abstract
A driving voltage control device includes a first to fourth capacitor, and an output section. In the first mode, the first capacitor receives a first voltage and stores a corresponding amount of charge, the second capacitor receives a second voltage and stores a corresponding amount of charge, and the output section supplies either one of a voltage according to the amount of charge stored in the first capacitor or second capacitor to a first output node according to a predetermined timing. In the second mode, the third capacitor receives a third voltage and stores a corresponding amount of charge, the fourth capacitor receives a fourth voltage and stores a corresponding amount of charge, and the output section supplies either one of a voltage according to the amount of charge stored in the third capacitor or fourth capacitor to a second output node according to a predetermined timing.
