Abstract
According to an aspect, a display apparatus includes: a display device that displays an image; and a drive circuit that drives the display device. The display device includes a regulator that supplies power based on a predetermined set voltage, a plurality of functional blocks that are operated by the supply of the power from the regulator and are related to operation of the display device, a voltage monitoring circuit that determines whether a level of a power supply voltage of at least one of the functional blocks is high or low based on a predetermined threshold voltage, and a voltage controller that increases the set voltage when the voltage monitoring circuit determines that the power supply voltage of the functional block is lower than the threshold voltage.
