Abstract
An organic light emitting diode display and a compensation method of driving characteristics thereof are discussed. The organic light emitting diode display includes a first pixel connected to a reference voltage line and a first data line, a second pixel sharing the reference voltage line and connected to a second data line, a data driver configured to output a data voltage to first and second output channels during a display period and acquire a sensing voltage of the first and second pixels through the reference voltage line during a compensation period, a first switch connected between the first output channel and the first data line, and a second switch connected between the second output channel and the second data line. The second switch is turned off during a first compensation period for detecting driving characteristic of the first pixel.
