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.

Organic light emitting display device and method for driving thereof

Disclosed herein are a light emitting display which can compensate for a threshold voltage of a driving switching element, and a method for driving the same. A light emitting display includes a pixel circuit that outputs a driving current corresponding to a data voltage from a data line using a scan signal, a first driving voltage and a second driving voltage; and a light emitting element that emits light by the driving current from the pixel circuit.
