1. A display apparatus comprising:
a display panel;
a sensing circuit performing a first sensing process on each of some pixels of the display panel to obtain a first sensing value during a first sensing period and performing a second sensing process on each of all pixels of the display panel to obtain a second sensing value during a second sensing period; and
a compensation circuit calculating a plurality of second sensing deviation values between adjacent pixels, based on a plurality of second sensing values of the adjacent pixels, obtaining a compensation value for each of the some pixels, based on a plurality of first sensing values, and obtaining a delta compensation value for each of other pixels which are pixels on which the first sensing process is not performed, based on the plurality of first sensing values and the plurality of second sensing deviation values.
