Abstract: A light emitting display apparatus can include a panel including a gate driver configured to output gate pulses and pixels configured to display an image; a power supply configured to supply a stage driving voltage to the gate driver and adjust a level of the stage driving voltage based on a dummy stage sensing signal received from the gate driver; and a data driver configured to supply data voltages to the pixels and generate a determination signal related to an occurrence of an abnormality in the gate driver based on a monitoring signal received from the power supply. Also, the light emitting display apparatus can further include a control driver configured to receive the determination signal from the data driver and control the power supply to adjust the level of the stage driving voltage based on a lookup table.
