Abstract: A light emitting display apparatus can include a control driver configured to perform a deterioration prevention function, a scaler configured to transmit a deterioration prevention function activation request signal to the control driver and transmit a deterioration prevention function deactivation request signal to the control driver based on an analysis result of input image data when deterioration prevention function start information is received from the control driver, and a light emitting display panel configured to display images under control of the control driver. The amount of change in an image used in the scaler is smaller than the amount of change in an image used in the control driver.
