Abstract

The invention discloses a fan-out wire structure, a display panel and a display device. The fan-out wire structure comprises a first metal layer, a second metal layer and a third metal layer arranged by stacked insulation, wherein the first metal layer comprises a first sub-metal layer and a second sub-metal layer not directly connected with each other, the third metal layer comprises the first sub-metal layer and the second sub-metal layer not directly connected with each other, the first sub-metal layer of the first metal layer is connected through the first sub-metal layer of the third metal layer with one end of the second metal layer, the other end of the second metal layer is connected through the second sub-metal layer of the third metal layer with the second sub-metal layer of the first metal layer, the value of resistance of the fan-out wire structure is adjusted by modulating the parameters of the second sub-metal layer and / or the third metal layer, the parameters comprise at least one of the following: length and width. By the scheme of the fan-out wire structure, the aim of the delay consistency of the internal signal of the panel is achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a fan-out wire structure and a display panel. Background technique [0002] The LCD panel industry has experienced decades of development. The VA (vertical alignment) display mode has become a common display mode for large-size TV TFT-LCDs due to its advantages such as wide viewing angle, high contrast, and no need for frictional alignment. Large size, high ppi (pixels per inch) products are the consistent pursuit of the display industry. Due to the limitations of product size, peripheral boarder, and utilization rate of large boards, it is difficult to design equal-resistance wiring when designing fanout wiring. Generally speaking, the panel signal is provided by COF, and each COF (Chip On Flex, or, Chip On Film, often called chip-on-film) is responsible for the signal of an area, and the signal is introduced into the plane through the fan-shaped fanout wiring connected to...
