Abstract

The invention provides a display panel. The display panel comprises a plurality of data lines, a plurality of constant-voltage wires and a plurality of driving wires, wherein the data lines and the constant-voltage wires are located in a display area, and the driving wires are electrically connected with the data lines and a driving chip. The display panel further comprises a first metal layer, a second metal layer and a shielding layer located between the first metal layer and the second metal layer, the first metal layer comprises a plurality of grid wires, the shielding layer comprises a plurality of shielding wires electrically connected with the constant-voltage wires, and the second metal layer comprises driving wires electrically connected with the grid wires. The overlapping area of the orthographic projection of at least part of the driving wires on the shielding layer and the orthographic projection of at least part of the gate wires on the shielding layer is overlapped with the shielding wires. The signal between the driving wire and the gate wire is shielded by using the shielding wire, so that the interference of the signal in the driving wire on the signal in the gate wire is weakened or eliminated.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel. Background technique [0002] As the proportion of the display area of ​​the OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel continues to increase, and the market demand for special-shaped frames, it poses a relatively large challenge to the wiring space at the edge of the display panel. The part of the display panel that occupies a relatively large proportion of the edge space is the part where the signal lines drawn from the driver chip enter the display area. Generally, the leads are distributed in a fan shape, also known as fan-out wiring. In order to adapt to the current situation that the edge of the display panel is gradually reduced, a design scheme of laying out fan-out lines in the display area is proposed, and this design scheme has gradually become a key technology for compressing the edge size of the dis...
