Claim Text:
1. An organic light emitting display, comprising: a scan driver configured to sequentially supply scan signals to scan lines; a data driver configured to supply data signals to data lines in synchronization with the scan signals; a switch unit coupled directly to output terminals of the data driver and coupled directly to the data lines; pixels located at crossing regions of the scan lines and the data lines, each of the pixels comprising a driving transistor; a timing controller configured to determine a normal driving mode for displaying a normal image or a standby driving mode for displaying less information than the normal image; and a power source configured to supply a first power and a second power to the pixels and a third power and a fourth power to the switch unit, wherein a voltage difference between the first power and the second power in the normal driving mode is a first voltage, and a voltage difference between the first power and the second power in the standby driving mode is a second voltage different from the first voltage, wherein the data driver is configured to supply the data signals corresponding to a first plurality of gray levels having a first bit resolution (2 wherein, in the standby driving mode, the switch unit is configured to transmit, selectively, the voltages of the third power and the fourth power to the data lines in accordance with the data signals corresponding to the second plurality of gray levels, and wherein j is greater than k.
