An organic light emitting display and an image compensation method improves the Long Range Uniformity (LRU) of the output image by displaying the identical image when the identical image is input to each pixel, by measuring the luminance, chromaticity coordinates and color temperature after an organic light emitting display panel is fabricated, by storing the compensation values thereof in a memory in the form of a look-up table in advance, and by compensating one of a power supply voltage, a data voltage and a light emission time. The organic light emitting display device and an image compensation method includes: a video signal processor; a control unit coupled to the video signal processor to compensate the luminance, chromaticity coordinates and color temperature in order to have the identical output image in relation to the identical input image; and an organic light emitting display panel coupled to the control unit to display the compensation image in which the luminance, chromaticity coordinates and color temperature have been compensated.
