Abstract: An organic light emitting display device includes a display panel having a plurality of sub-pixels; a memory configured to accumulate and store data displayed by each sub-pixel; and a panel driver configured to: calculate a degradation compensation gain value for increasing or decreasing a luminance of each sub-pixel based on accumulated data of each sub-pixel stored in the memory, generate modulated data of each sub-pixel by modulating input data to each sub-pixel according to the calculated degradation compensation gain value, convert the modulated data into a data voltage, and accumulate the modulated data from the accumulated data of the corresponding sub-pixel and then store the data in the memory.

Abstract: An organic light-emitting display device includes: an organic light-emitting panel defined into a plurality of pixel regions which each includes a drive transistor configured to drive an organic light emission element and a load capacitor configured to charge a threshold voltage of the drive transistor; and a controller configured to calculate an offset information on the basis of the threshold voltage and derive a second image signal by reflecting the offset information to a first image signal.
