Abstract

The invention discloses a fan-out line structure, a display panel and a display device. The fan-out line structure comprises a first wiring layer, a second wiring layer and fan-out lines. The first wiring layer and the second wiring layer are arranged in parallel. The fan-out lines comprise a plurality of pairs of first fan-out lines and second fan-out lines. The first fan-out lines are arranged on the first wiring layer. The second fan-out lines are arranged on the second wiring layer. Each first fan-out line is provided with a corresponding first impedance unit. Each second fan-out line is provided with a corresponding second impedance unit. The first impedance unit is provided with a first ion implantation region for implanting ions so as to change the resistance of the first impedanceunit. A second ion implantation region is arranged on the second impedance unit and is used for implanting ions so as to change the resistance value of the second impedance unit. The fan-out line structure provided by the invention adopts double-layer wiring, so that the high-resolution data wiring requirement of a large-size display panel can be met. The impedance difference of the fan-out wirescan be balanced by arranging the impedance units on the fan-out wires.

Description

technical field [0001] The invention relates to the display field, in particular to a fan-out line structure, a display panel and a display device. Background technique [0002] In the Low Temperature Poly-silicon (LTPS) display field, due to the advantages of high aperture ratio and high resolution of LTPS, more and more medium-sized or even large-sized display panels tend to use LTPS manufacturing technology. [0003] However, medium and large-sized display panels have high requirements on the uniformity of data trace impedance, especially in the field of large-scale display panels. line needs. Generally, in the design of small and medium-sized displays, a single layer of metal is used, because the size of the display panel is small, and the difference in impedance at different positions of the display panel is small, which is within an acceptable range. However, with the continuous increase of display panels, such as figure 1 As shown, the distance at the diagonal line...
