ORGANIC LIGHT EMITTING DISPLAY DEVICE AND COMPENSATION METHOD THEREFOR

Abstract:

The present disclosure relates to an organic light emitting display device. The device includes, among others, a controller including a data compensator configured to accumulate stress data applied to organic light emitting diodes (OLEDs) on the basis of input image data, to generate accumulated stress data under a condition for recovery of accumulated loss in a loss region, to compress and restore the accumulated stress data in a lossless manner and a loss manner to determine a compensated value and to output the compensated value. Accordingly, it is possible to estimate previous loss data on the basis of new image data to be currently accumulated, recover loss and accumulate data to prevent accumulation of loss and efficiently compensate for afterimage due to deterioration of OLEDs to extend the period of use.
