Problems solved by technology

During the entire subsequent manufacturing process of the flexible display panel, these pure metal traces are very likely to be damaged by trace cracking, disconnection, oxidation or scratches due to their own characteristics or external factors.
In particular, the pure metal wiring in the prior art generally uses Mo or Al. Mo has poor ductility and is easy to break when bent, while Al is easily oxidized, resulting in increased resistance; these problems will seriously affect the flexibility. Normal operation of the display panel

Abstract

The invention relates to a flexible display panel and a manufacturing process thereof. The flexible display panel comprises a flexible substrate, a display element, an encapsulation structure, a plurality of first contact terminals, a plurality of second contact terminals and a conductive connecting unit, wherein the conductive connecting unit comprises a patterned conductive film layer, which is provided with a lead pattern electrically connecting the first contact terminals and the second contact terminals. According to the flexible display panel, the conductive film layer with the lead pattern is arranged between the first contact terminals and the second contact terminals, so that the problem of that pure metal wiring in the prior art is prone to resulting in bending and fracture can be solved; also, the problems existing in pure metal wiring of flexible display panels in the prior art such as bending, fracture, oxidation and scratching can be solved, and the yield rate of the display panel products can be greatly improved.

Description

technical field [0001] The invention relates to a flexible display panel and a manufacturing process thereof. Background technique [0002] With the development of display technology, flexible display panels have been more and more widely used due to their advantages of low power consumption, bendability and folding. Flexible display panels include OLED flexible display panels, liquid crystal flexible display panels, and the like. [0003] Generally speaking, there are a large number of pure metal traces in the bending area of ​​the flexible display panel. Taking an organic light-emitting flexible display panel as an example, there are a large number of pure metal traces (for example, used for electrically connecting IC chips and inputting IC signals) in the bending area of ​​the flexible substrate. These pure metal traces are generally manufactured in the same process as the metal layer on the flexible substrate. Therefore, when the flexible TFT substrate manufacturing pr...
