Abstract: A panel defect detection method and an organic light emitting display device. A region having a high probability of a panel defect is intensively sensed through panel defect detection based on sensing results of characteristic values according to subpixels on sensing subpixel lines in an amount equal to the number of sensing subpixel lines preset in specific regions rather than all regions of a display panel. Rates and accuracy in detection of panel defects can be improved.
