Abstract
A display device includes a display panel having a plurality of sensing channels connected to a plurality of subpixels to detect a driving characteristic value, a data driving circuit including an analog-to-digital converter converting a sensing voltage detected through the plurality of sensing channels into digital sensing data and converting a subpixel driving voltage detected through at least one dummy channel into digital dummy sensing data, and a timing controller calculating an intensity of a current flowing through the data driving circuit based on the digital dummy sensing data transferred from the data driving circuit and compensating for image data transferred to the data driving circuit.
