Abstract:
1. An organic light emitting display, comprising: a first power supply to receive an initial voltage and to supply a first power including a first high voltage and a first low voltage; a second power supply to supply a second power including a second high voltage and a second low voltage; and an organic light emitting display panel having a display mode including a standard display mode and a low power display mode, the organic light emitting display panel to receive the first power from the first power supply in the standard display mode and to receive the second power from the second power supply in the low power display mode, wherein: the second power supply includes a gamma compensator to receive the second high voltage directly and to compensate a gamma value of an image that is output to the organic light emitting display panel, the first high voltage is generated by boosting the initial voltage, and the first low voltage is generated by dropping the initial voltage, and the second high voltage and the second low voltage are the voltages used by the organic light emitting display panel, and whether the display mode is changed or not is determined by each frame.
