Claim Text:
1. An organic light emitting display comprising: a display panel; a data driver supplying a data signal to the display panel; a timing controller controlling the data driver; a power source supply unit converting an external voltage supplied from an outside and outputting a high potential voltage and a low potential voltage through a first power source line and a second power source line; a measurement unit measuring a current or a voltage flowing through the first power source line and the second power source line from the power source supply unit and outputting a measured value; and a compensation coefficient calculator matching the measured value and a reference value stored in the compensation coefficient calculator to a driving signal supplied from the timing controller and comparing the measured value and the reference value to judge a degree of noise occurring at an output end of the power source supply unit, and calculating a compensation coefficient according to the degree of noise, wherein the compensation coefficient is supplied to the timing controller and includes information of a specific frame period and specific data signal to compensate, and wherein the timing controller compensates the specific data signal during the specific frame period based on the information of the compensation coefficient.
