Claim Text:
1. An organic light emitting diode display comprising: a display comprising a plurality of data lines, a plurality of scan lines, a plurality of sense lines, and a plurality of pixels electrically coupled to the data lines, the scan lines, and the sense lines; a compensator configured to sense first driving currents and second driving currents flowing to the pixels corresponding to first test data and second test data, respectively, in a compensation mode, to compare first reference currents and second reference currents with the first driving currents and the second driving currents, respectively, and to update compensation data corresponding to a variation of a mobility characteristic variable and a variation of a threshold voltage characteristic variable by selectively increasing or decreasing at least one of the variation of the mobility characteristic variable and the variation of the threshold voltage characteristic variable based on a result of the comparison; a signal controller configured to compensate input data according to the compensation data to generate image data, and to change the input data into the first test data and the second test data in the compensation mode; and a data driver configured to generate a plurality of data signals by using one of the image data, the first test data, and the second test data, and to supply the data signals to the data lines.
