Abstract:
1. An organic light emitting display, comprising: a display unit comprising sub-pixels arranged in columns, the sub-pixels comprising first sub-pixels, second sub-pixels, and third sub-pixels for emitting light corresponding to different colors and that are located at crossing regions of scan lines and data lines, the columns comprising a first column, a second column adjacent to the first column, a third column adjacent to the second column, and a fourth column adjacent to the third column, the first and third columns comprising the first and second sub-pixels, the second and fourth columns comprising the third sub-pixels, the data lines comprising first and fourth data lines respectively coupled to every other one of the sub-pixels in the first and third columns, second and fifth data lines respectively coupled to every other one of the sub-pixels in the first and third columns, and third and sixth data lines respectively coupled to every one of the sub-pixels in the second and fourth columns; a scan driver for supplying scan signals to the scan lines; a data driver coupled to one end of each of the data lines, for supplying data signals to the data lines; a switch unit coupled between the one end of each of the data lines and the data driver to transmit the data signals supplied from output lines of the data driver to the data lines, the output lines comprising a first output line coupled by the switch unit to the first and second data lines, a second output line coupled by the switch unit to the third data line, a third output line coupled by the switch unit to the fourth and fifth data lines, and a fourth output line coupled by the switch unit to the sixth data line; and a test circuit unit comprising a plurality of transistors coupled to other ends of the data lines, the transistors comprising first to sixth transistors respectively coupled to the first to sixth data lines.
