Abstract: Disclosed is a light emitting display device capable of minimizing deviation of current driving capability between driving switching devices of respective pixels, thereby achieving enhanced screen quality. A method of driving the light emitting display device includes sensing the threshold voltage and mobility of driving Thin Film Transistor (TFT) of each pixel through each data line or each power line using a first sensing voltage; correcting an error of the mobility between the driving TFTs by again sensing the mobility of the driving TFT of each pixel through each data line or each power line using a second voltage; and compensating for video data to be displayed on a display panel using the threshold voltage and the corrected mobility.

Abstract: A data processing method and an apparatus for an organic light emitting diode (OLED) display device are provided. The method includes modulating input data using a maximum degradation compensation gain, compensating degradation of the modulated data using a degradation compensation gain, accumulating the degradation-compensated data, determining a degree of degradation of each of sub-pixels, based on the accumulated data, detecting a degradation compensation gain in accordance with the determined degradation degree, storing the detected degradation compensation gain, and outputting the stored degradation compensation gain, detecting a maximum one of degradation compensation gains of respective sub-pixels, and outputting the detected maximum degradation compensation gain, analyzing the input data, thereby setting a peak luminance control (PLC) gain, and modulating the PLC gain, using the output maximum degradation compensation gain, and analyzing the degradation-compensated data, thereby detecting a peak luminance, and adjusting the detected peak luminance, using the modulated PLC gain.
