Abstract: An organic light emitting diode display and a method for sensing driving characteristics thereof are discussed. The organic light emitting diode display supplies a data voltage of an input image to pixels each including an organic light emitting diode in a driving mode and senses changes in driving characteristics of the pixels in a sensing mode. The organic light emitting diode display in one example includes a low potential power voltage adjustment unit configured to reduce a low potential power voltage of the pixels to a negative voltage in the sensing mode and adjust the low potential power voltage to a ground level voltage in the driving mode, and a sensing unit configured to sense an anode voltage of the organic light emitting diode using an analog-to-digital converter in the sensing mode.
