    Abstract: A power supply device includes a voltage range selector, a voltage level controller, and a power supply voltage generator. The voltage range selector generates a range selection signal to select a voltage control range. The voltage level controller generates a voltage level control signal based on a driving condition of a display panel. The power supply voltage generator generates a power supply voltage having a voltage level corresponding to the voltage level control signal within the voltage control range, and supplies the power supply voltage to the display panel.
