Claim Text:
1. A driving method of an organic light emitting display comprising: charging parasitic capacitance of data lines using a precharge voltage during a porch period that is positioned between a frame and a next frame; generating first digital values by sensing deterioration information of organic light emitting diodes respectively included in a plurality of pixels coupled to the data lines; storing the first digital values in a memory; charging the parasitic capacitance of the data lines using the precharge voltage during the porch period; generating second digital values by sensing threshold voltage and mobility information of driving transistors respectively included in the pixels; storing the second digital values in the memory; converting input data into calibration data according to information stored in the memory to display an image having a uniform brightness, irrespective of the deterioration information of the organic light emitting diodes and the threshold voltage and mobility information of the driving transistors; and supplying data signals in accordance with the calibration data to the data lines.
