ORGANIC LIGHT EMITTING DISPLAY DEVICE AND REPAIR METHOD THEREOF
First Claim
1. A repair method of an organic light emitting display device including a plurality of pixels each including an organic light emitting diode (OLED) in every pixel area and having a repair structure formed between two or more pixels adjacent to each other among the plurality of pixels in at least one of a horizontal direction and a vertical direction by one or more repair lines, the repair method comprising:
- cutting a connection between a driving TFT defective in operation and an anode electrode of an OLED of a first pixel among the two or more pixels;
repairing a source electrode of an in-defective driving TFT of a second pixel and the anode electrode of the OLED of the first pixel by welding the repair line and the driving TFT of the second pixel adjacent to the first pixel; and
operating the OLED of the first pixel through the driving TFT of the second pixel,wherein the repair line extends from the end of the anode electrode of the OLED of the first pixel to overlap the electrode of the driving TFT of the second pixel, andthe repairing includes welding the repair line and a source electrode of the driving TFT of the second pixel to connect the repair line and the source electrode of the driving TFT of the second pixel.

Abstract
By forming a repair structure in a horizontal direction and vertical direction by using one or more repair lines between two or more pixels adjacent to each other in a display panel, even though a dark spot appears due to a defective operation of one pixel, the one pixel may be compensated to be driven by using the other pixel.
