Abstract
Disclosed are an organic light emitting diode display, which can reduce image sticking caused by the deterioration of an organic light emitting diode, and a driving method thereof. The organic light emitting diode display comprises: a display panel comprising a plurality of pixels arranged in a matrix at intersections of gate line portions and data line portions and each having an organic light emitting diode; a memory for storing compensation data; a timing controller for modulating input digital video data based on the compensation data and generating modulated data; and a data driving circuit for, during compensation driving, generating the compensation data to compensate for a difference in the deterioration of the organic light emitting diodes by supplying a sensing voltage to the pixels and sampling the threshold voltage of the organic light emitting diodes, which is fed back from the pixels, and for, during normal driving, converting the modulated data into a data voltage and supplying the data voltage to the pixels.
