1. A light emitting display apparatus comprising:
a display panel configured to display an image;
a timing controller including:
a set value output unit configured calculate a refresh rate of the display panel based on a data signal which is to be supplied to the display panel;
an on bias stress (OBS) voltage calculator configured to calculate an OBS voltage value based on the calculated refresh rate of the display panel and the data signal; and
a power supply configured to generate an OBS voltage based on of the calculated OBS voltage value, the OBS voltage supplied to an electrode of a driving transistor of a pixel included in the display panel.
