description | Embodiments of the present disclosure relate to a display device, a data driving circuit, and a display driving method. More specifically, the display device may be provided, including: a display panel having a plurality of sensing channels connected to a plurality of sub-pixels to detect a driving characteristic value; a data driving circuit including an analog-to-digital converter which converts a sensing voltage detected through the plurality of sensing channels into digital sensing data and converts a sub-pixel driving voltage detected through the at least one dummy channel into digital dummy sensing data; and a timing controller which calculates an intensity of a current flowing through the data driving circuit based on the digital dummy sensing data transmitted from the data driving circuit, and compensates for image data transmitted to the data driving circuit. According to the present invention, the display device can prevent defects and deterioration of the image quality caused by changes in the sub-pixel driving voltage.
