Abstract
An organic light emitting display device and a method for providing low luminance power thereof includes a data driver including a lookup table storing therein a low potential voltage and an initialization voltage corresponding to each gamma set such that a low potential voltage and an initialization voltage in a 60 Hz operation mode are respectively different from a low potential voltage and an initialization voltage in a 90 Hz operation mode and a method compensates for an anode charging time in the low luminance range, thereby improving seamlessness.
