Abstract
A display device comprises pixels arranged along rows and columns, and including light-emitting elements, a first transistor for supplying a driving current to the light-emitting elements, a second transistor for supplying a data voltage to a first node at a gate electrode of the first transistor, a third transistor for electrically connecting a second node, which is at a first electrode of the light-emitting elements, and a sensing line, and a fourth transistor for electrically connecting a third node, which is at a second electrode of the light-emitting elements, and the sensing line, and a display driver for driving the pixels, for sensing voltages of the second node and the third node to calculate a driving voltage across the light-emitting elements, and for compensating for the data voltage in case that the driving voltage exceeds a reference voltage.
