Abstract
A display device includes: a display panel including a pixel electrically connected to each of a data line, a first power line, a second power line, and a third power line; a power supply to provide a first power voltage to the first power line, and a second power voltage to the second power line; and a driver to provide a data voltage to the data line, and a third power voltage to the third power line. The driver is to determine whether a sensing voltage measured at the second power line is out of a reference range, and to limit the supply of the third power voltage when the sensing voltage is out of the reference range.
