Abstract
Provided are an organic light emitting display and a method of manufacturing the same. The organic light emitting display includes: a display panel including a plurality of pixels, each pixel including: a light emitting element, and a driving element to drive the light emitting element, a data driving circuit to, within one horizontal display period: write sensing data to a pixel on a horizontal display line through a data line, sense the pixel current of the pixel through a reference line, and then write display data compensated by a first offset compensation value to the pixel, an offset calculator to calculate a second offset compensation value for compensating changes in the driving element over time based on the sensed value of the pixel current, and an offset memory to update the pre-stored first offset compensation value with the second offset compensation value when display data writing is stopped.
