Abstract
A present disclosure relates to a method of sensing characteristic value of circuit element and display using it. The display device is able to accurately sense deterioration of the organic light-emitting diode disposed in each subpixel of a display panel and compensate for the deterioration. The method of sensing characteristic value of circuit element is able to save a sensing time for an entire display panel and improve a driving speed of the display device by efficiently performing a deterioration sensing process of the organic light-emitting diode.
