Claim 0:
1. An organic light emitting diode (OLED) display comprising:
a display panel comprising a plurality of first pixels configured to emit a first color light, a plurality of second pixels configured to emit a second color light, and a plurality of third pixels configured to emit a third color light, the first through third pixels being arranged at locations corresponding to crossing points of a plurality of scan-lines and a plurality of data-lines;
a scan driver configured to sequentially output a scan signal to the display panel;
a data driver configured to alternately output a first data signal to be applied to the first pixels to emit the first color light corresponding to one horizontal period and a second data signal to be applied to the second pixels to emit the second color light corresponding to the one horizontal period to the display panel, configured to output a third data signal to be applied to the third pixels to emit the third color light corresponding to the one horizontal period to the display panel, and configured to begin outputting the first data signal at a first point of time in a period immediately preceding the one horizontal period and end outputting the first data signal at a second point of time in the one horizontal period;
a demultiplexing unit configured to alternately apply the first and second data signals to the first and second pixels, respectively, the demultiplexing unit being placed between the display panel and the data driver; and
a timing controller configured to control the scan driver, the data driver, and the demultiplexing unit,
wherein the data driver is configured to directly apply the third data signal to the third pixels, and
wherein the first to third data signals are effective data signals that are applied to the first to third pixels, respectively, during the one horizontal period.
