Abstract
An electroluminescent display apparatus may include: a display panel including a pixel; a data voltage supply circuit configured to supply a sensing data voltage to the pixel in a sensing period within a vertical blank period of a first frame, to supply a recovery data voltage to the pixel in a recovery period following the sensing period, and to supply a display data voltage to the pixel in a vertical active period of a second frame following the first frame; and a sensing circuit configured to sense an electrical characteristic of the pixel based on the sensing data voltage in the sensing period within the vertical blank period of the first frame. A level of the display data voltage to be supplied to the pixel in the vertical active period of the second frame may be determined based on a length of the vertical blank period of the first frame.
