PROBLEM TO BE SOLVED: To provide an organic light emitting display which offers shorter sensing time and higher sensing accuracy when sensing variations in electrical characteristics of a driving element.SOLUTION: The organic light emitting display includes: a display panel with pixels; a gate driving circuit that generates a sensing gate pulse corresponding to one line sensing ON time in a sensing operation and then sequentially supplies the same to gate lines in a line sequential manner; a data driving circuit which comprises a plurality of current integrators that perform an integration of the source-drain current of the driving TFT of each of the pixels input through the sensing lines in the one line sensing ON time in the sensing operation, and an ADC that sequentially digitizes the output of the current integrators to output digital sensed values; and a timing controller that controls the operations of the gate driving circuit and the data driving circuit. |
