1. A light-emitting display apparatus comprising:
a display panel configured to display an image;
a driving circuit configured to drive the display panel;
a timing controller configured to control the driving circuit; and
a compensation circuit configured to correct an accumulation period difference of accumulated data to compensate deterioration of an element included in the display panel based on fluctuation of a driving frequency for driving the display panel,
wherein the timing controller is configured to calculate a correction time for correcting an accumulation period difference due to a difference of a frequency lower or higher than a reference frequency, and
wherein the timing controller is configured to correct the accumulation period difference of accumulated data that has accumulated based on the correction time in order to compensate for deterioration of an element included in the display panel.
