Abstract
A semiconductor device for controlling a display device includes a generation unit configured to generate a reference voltage, a booster unit configured to boost the reference voltage to generate a bias voltage, and a conversion unit. The conversion unit receives a status signal generated from a power supply voltage and is configured to boost a voltage level of the status signal to that of the bias voltage for controlling drive of the display device. A control unit is configured to stop operation of at least one of the generation unit and the booster unit when one of a value of the power supply voltage and a value of a power supply current flowing from a power supply that generates the power supply voltage is lower than a predetermined threshold.
