Abstract: An electroluminescent display apparatus includes a display panel, a sensing circuit performing a first sensing process on some pixels of the display panel to obtain a normal sensing value during a first sensing period and performing a second sensing process on all pixels of the display panel to obtain a temporary sensing value during a second sensing period, and a compensation circuit calculating a temporary sensing deviation value between adjacent pixels, based on the temporary sensing value, obtaining a compensation value for the some pixels, based on the normal sensing value, and obtaining a delta compensation value for the other pixels except the some pixels, based on the normal sensing value and the temporary sensing deviation value.
