Abstract

The invention discloses a display panel and a display device. The display panel comprises a first fan-out area; a binding area arranged at one side of the first fan-out area; a second fan-out area arranged at one side, far away from the first fan-out area, of the binding area; first metal wires arranged in the first fan-out area and the second fan-out area; second metal wires arranged in the firstfan-out area and the second fan-out area, wherein the resistivity of the second metal wires is smaller than that of the first metal wires; and connecting wires. One end of each connecting wire is connected to the first metal wire, and the other end of each connecting wire is connected to the second metal wire. The display panel and the display device have the advantages that the resistivity of the second metal layer is smaller than that of the first metal layer, the two ends of each connecting wire of the binding area are connected with the first metal layer and the second metal layer respectively, the resistance value difference of any two connecting wires is reduced, the current stability is improved, and the display quality of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode) is more and more widely used due to its light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, and fast response speed. In order to improve the display uniformity of the OLED panel, the second metal layer is used to make a metal grid structure and VDD signal connection. Currently, the wiring in fanout1 (first fan-out area) & fanout2 (second fan-out area) outside the display area uses GE1 (first metal layer) / GE2 (second metal layer) are routed alternately, and GE1 / GE2 are made of the same material, have the same film thickness, and have the same resistance. However, after GE2 (the second metal layer) is made of low-resistance materials, the resistance of GE1 / GE2 traces is quite different, and the current alternate...
