Abstract
A display device includes: a display panel including scan lines, a first power line, a second power line, and pixels connected to the scan lines and the first and second power lines; a gate driver to sequentially provide scan signals to the scan lines based on a clock signal; and a power supply including transistors to convert an input power voltage into a first power voltage through a switching operation of the transistors and to supply the first power voltage to the first power line through a first output terminal. In response to an amount of current flowing through the pixels being less than a first reference current amount, the power supply is configured to change one or more of an off-duty of at least one of the transistors, a channel capacitance of at least one of the transistors, a switching frequency of at least one of the transistors, and a slew rate of at least one of control signals for the transistors.
