Summary: | An electroluminescent display device includes a pixel configured to display an image based on a difference between a display data voltage and a first reference voltage, a driving voltage generation circuit configured to supply the display data voltage to the pixel through a data line, and a sensing circuit configured to supply the first reference voltage to the pixel through a sensing line. The sensing circuit includes a sensing channel terminal coupled to the sensing line, a switch coupled between the sensing channel terminal and an input terminal for the first reference voltage, and a sampling circuit configured to sense a voltage of the sensing line which has changed from the first reference voltage independent of driving characteristics of the pixel in a vertical blank period in which the switch is turned off. |
