Abstract
A display device may include a display panel and a driver circuit. The display panel may include subpixels, data lines, and reference voltage lines. The driver circuit may drive the data lines. A first subpixel may be connected to a first data line and a first reference voltage line. A driving time of the first subpixel may include a first initialization time in which a reference voltage is applied to the first reference voltage line and a first tracking time in which a voltage of the first reference voltage line increases from the reference voltage. During the first tracking time, a first data signal transferred to the first subpixel through the first data line may be changed from a first voltage value to a reference driving voltage value. The first voltage value may be higher than the reference driving voltage value. The display device may reduce a sensing time.
