Abstract
An organic light emitting display device and a method of repairing the device are discussed. According to an embodiment, the device includes a display panel having pixels, each including an OLED in every pixel area defined as scan and data lines intersect with each other and having a repair structure in at least one of horizontal and vertical directions between adjacent pixels by one or more repair lines; a timing controller configured to generate compensation data when a dark spot is generated in one of the plurality of pixels of the display panel, and adjust a magnitude of image data according to the compensation data; and a data driver configured to adjust a magnitude of a data voltage according to the image data adjusted in magnitude, and output the data voltage adjusted in magnitude to the data lines.
