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.

Abstract: An embodiment of the present invention provides a light emitting display device including a display panel including M (M being an integer equal to or greater than 2) subpixels sharing a single sensing line, and a circuit for sensing elements included in at least one of the M subpixels through the sensing line. A first subpixel from among the M subpixels can be defined as a sensing subpixel, a second subpixel can be defined as a non-sensing subpixel. The second subpixel can have an initial period for applying an initialization voltage for a time longer than a data writing period for applying a sensing voltage to the first subpixel.
