Abstract

The invention discloses a display panel, a display device and a repairing method of the display panel. A fan-out area is provided with a plurality of first fan-out lines; the first ends of the first fan-out lines are electrically connected with at least one signal line of the display area; the second ends of the first fan-out lines are electrically connected with the binding bonding pad of the binding area; the fan-out area is also provided with a detection circuit; the output end of the detection circuit is electrically connected with the first fan-out wire; the detection circuit is used forinputting a test signal to the sub-pixels of the display area through the first fan-out lines before the display panel is bound with the driving chip; the fan-out area further comprises a plurality ofsecond fan-out lines; the second fan-out lines are connected with the first fan-out lines in parallel; the connection points of the first ends of the second fan-out lines and the first fan-out linesare first nodes; the connection points of the second ends of the second fan-out lines and the first fan-out lines are second nodes; the first nodes are located between the detection circuit and the display area; and the second nodes are located between the binding area and the display area, and the yield of the display panel is improved.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a display panel, a display device and a repair method for the display panel. Background technique [0002] In the existing display panel, in order to improve the yield rate of the display panel and prevent defective products from flowing into the client, the display panel is generally checked by lighting before the display panel is bound to the driver chip, and the display panel is checked by inputting various analog signals. functional deficiencies. In order to increase the detection rate, a detection circuit is generally used to perform a lighting test on the display panel. Wherein, the detection circuit in the display panel inputs test signals to the sub-pixels in the display area through fan-out lines. [0003] When the signal port of the detection circuit or the signal port of the driver chip is exposed, the exposed signal port is easy to introduce static electricit...
