The invention discloses a display panel LED repairing method and device and a display panel. The method comprises the following steps: determining an LED dead pixel on a display panel; forming a channel surrounding the LED dead pixel on the connecting layer around the LED dead pixel, wherein the connecting layer is used for connecting the LED and a back plate of the display panel; coating the LED dead pixels with an LED connecting layer dissolving solution, and dissolving the connecting layer corresponding to the LED dead pixels; and supplementing a normal LED at the LED dead pixel. The back plate can be prevented from being damaged in the channel forming process. And then the LED dead pixel is coated with an LED connecting layer dissolving solution, the LED connecting layer dissolving solution dissolves the connecting layer corresponding to the LED dead pixel, and the purpose of directionally removing the connecting layer at the LED dead pixel is achieved. And then the normal LED is supplemented at the LED d
