Abstract
A display device, a data driving circuit and a display driving method are discussed. The display device can include a display panel in which a plurality of subpixel circuits including a light emitting element, a driving transistor, and a sensing transistor are disposed. The display device further can include a gate driving circuit configured to supply a plurality of scan signals to the display panel through a plurality of gate lines, a data driving circuit configured to supply a plurality of data voltages to the display panel through a plurality of data lines and supply a constant current to the plurality of subpixel circuits during a resistance sensing period, and a timing controller configured to control the gate driving circuit and the data driving circuit, and supply compensation image data to the display panel by using the resistance of the sensing transistor detected in the resistance sensing period.
