Claim Text:
1. An organic light emitting diode display device, comprising: a display panel including a plurality of pixels in a display region, each pixel including a switching thin film transistor, a driving thin film transistor, and a light emitting diode, the display region divided into a plurality of regions; a diode current measuring portion electrically connected to the light emitting diode of each pixel and measuring a current of each divided region to generate a contour plot of luminance based on the measured current; a timing control portion obtaining a gain value of each divided region based on the measured current of each divided region, and generating compensated image data using the gain value to compensate for non-uniformity of luminance in the display region according to the contour plot of luminance generated based on the measured current; a gate driver supplying gate voltages to the display panel; and a data driver supplying data voltages corresponding to the compensated image data to the display panel.
