Abstract
A method of driving a display device including a sensing line, a light-emitting element, a capacitor, and a driving transistor, the driving transistor comprising a control terminal that is connected to the capacitor, an input terminal, and an output terminal, the method including: connecting the control terminal and the output terminal; connecting the control terminal and the output terminal to a ground voltage and then disconnecting the control terminal and the output terminal from the ground voltage; sensing a first voltage of the control terminal through the sensing line; and calculating a threshold voltage of the driving transistor based on the first voltage.
