Abstract
A gate driver for an organic light emitting display device comprises a selector configured to select and output one of a first low voltage and a second low voltage in response to a mode selection signal, wherein the first low voltage is selected in a first mode and the second low voltage is selected in a second mode, and the second low voltage has a lower level than the first low voltage, and a level shifter configured to generate a clock signal based on a high voltage and the first low voltage, to output the clock signal at a first output terminal, and to generate a direct current signal corresponding to the first or second low voltage outputted from the selector and to output the direct current signal at a second output terminal, wherein the high voltage is a voltage level higher than the first low voltage and the clock signal is a voltage level between the high voltage and the first low voltage.
