Abstract: An application processor includes a scaling rate calculator that determines a scaling rate of first image data based on stress data that includes pixel degradation information for each pixel; and an image processor that generates second image data by decreasing a maximum grayscale value of the first image data based on the scaling rate, where the first image data is received from an external component.

Abstract: An organic light emitting display device includes: a display panel including a plurality of pixels; a controller configured to correct input image signals supplied from the outside according to an amount of voltage drop; a data driver configured to supply data signals corresponding to the corrected image signals; and a scan driver configured to supply scan signals to scan lines. The controller includes: a load factor calculator configured to calculate a load factor of a panel; a horizontal block load factor calculator configured to calculate a driving current of a plurality of horizontal blocks formed by dividing the panel according to the scan lines; a voltage drop amount calculator configured to calculate the amount of the voltage drop based on the driving current; and a lookup table generator configured to generate a voltage drop correction lookup table based on the amount of the voltage drop.
