Abstract
A display device can include a display panel having subpixels each including a driving transistor; a data driver to drive data lines and reference lines connected to the subpixels; a timing controller to control the data driver; and a power management circuit to supply a reference voltage to the reference lines. Also, the data driver receives the reference voltage of a first specific level for a first row line of the subpixels from the power management circuit and supplies the reference voltage of the first specific level to the first row line as an initialization voltage during a threshold voltage sensing mode, and receives the reference voltage of a second specific level for a second row line of the subpixels from the power management circuit and supplies the reference voltage of the second specific level to the second row line as the initialization voltage during the threshold voltage sensing mode.
