Abstract
Disclosed is a display apparatus comprising a display panel including data lines connected to a driving transistor of each of subpixels for displaying an image, and reference lines connected to a sensing transistor of each of the subpixels, a data driver configured to supply a data voltage to the data lines and supplying a reference voltage to the reference lines, and a timing controller configured to control the data driver, sense a reference voltage deviation of each of the reference lines changed independent from a driving characteristic of a subpixel by supplying the reference voltage to the reference lines without supplying the data voltage to the data lines, and compensate for the reference voltage deviation.
