Claim Text:
1. An organic light emitting diode (OLED) display device comprising: a display panel comprising a plurality of pixels, each comprising a light emitting device and a driving thin film transistor (TFT) for supplying driving current to the light emitting device; a gate driver for driving gate lines connected to each pixel; a data driver for sensing a threshold voltage and a mobility of the driving TFT using a sensing line connected to each pixel in a measurement mode, and applying a data voltage to data lines connected to each pixel in a display mode; and a timing controller for sorting image data input from an external source and supplying the image data to the data driver in the display mode, wherein the timing controller comprises: wherein: the peak luminance controller sets the peak luminance to a maximum luminance when the APL is 0 to a reference level and sets the peak luminance to decrease down to a minimum luminance from the maximum luminance when the APL is the reference level to 1; and the data compensator sets the weight of the gain value to a first percentage of a maximum gain value or less when the APL is 0 to the reference level, and sets the weight of the gain value to increase to the maximum gain value from the first percentage of the maximum gain value when the APL is the reference level to 1.
