Claim 18:
19. A display apparatus comprising:
a display panel including a plurality of pixels that are connected to a plurality of data lines, a plurality of sensing lines and a plurality of scan lines, each of the plurality of pixels including an organic light emitting diode and a first transistor for driving the organic light emitting diode;
a scan driver driving the plurality of scan lines; and
a data driver driving the plurality of data lines based on a plurality of sensing data that represent operating characteristics of the plurality of pixels, and including a plurality of sensing circuits obtaining the plurality of sensing data through the plurality of sensing lines, each of the plurality of sensing circuits comprising:
a first switch providing an initialization voltage to one of the plurality of sensing lines; and
an analog-to-digital converter performing an analog-to-digital conversion on a sensing value obtained from the one of the plurality of sensing lines,
wherein, when pixels arranged in a same pixel row among the plurality of pixels display a same grayscale, the image is displayed on the display panel by adjusting levels of a plurality of data voltages depending on positions of the pixels arranged in the same pixel row and by applying the plurality of data voltages having different levels to the plurality of data lines.
