Abstract:
1. An organic light emitting display comprising: a display region comprising a plurality of pixels, each pixel comprising at least two sub-pixels having different colors; a data driver for outputting data signals to signal lines; and a data signal switch for receiving the data signals through the signal lines and transmitting the data signals through data lines to the sub-pixels, the data signal switch being configured to switch a correspondence between two of the signal lines and two of the data lines in accordance with a single gamma conversion signal, the two of the signal lines for transmitting two of the data signals to two of the sub-pixels in a same one of the pixels through the two of the data lines, a first signal line of the two of the signal lines for transmitting a first data signal of the two of the data signals to one of a first data line or a second data line of the two of the data lines while a second signal line of the two of the signal lines transmits a second data signal of the two of the data signals to another of the first data line or the second data line, wherein the data signal switch comprises a first switch and a second switch each having a first terminal electrically connected to the first signal line and a third switch and a fourth switch each having a first terminal electrically connected to the second signal line while the first signal line transmits the first data signal to the one of the first data line or the second data line and the second signal line transmits the second data signal to the other of the first data line or the second data line, the first, second, third, and fourth switches being controlled by the gamma conversion signal, and wherein the first and third switches each have a second terminal electrically connected to the first data line and the second and fourth switches each have a second terminal electrically connected to the second data line while the first signal line transmits the first data signal to the one of the first data line or the second data line and the second signal line transmits the second data signal to the other of the first data line or the second data line.
