Abstract

The embodiment of the invention provides a manufacturing method of a flexible display panel. The manufacturing method comprises the following steps of providing or preparing a module material; preparing a first organic material layer at the surface of the module material; preparing a metal route layer at the surface of the first organic material layer; performing heat treatment on the first organic material layer and the metal route layer, so as to enable the metal route layer to form a wrinkle structure at the surface of the first organic material layer. The manufacturing method has the advantages that by adopting the heat treatment technology to form the wrinkle structure on the metal route layer and the first organic material layer, the heat expansion difference of the metal route layerand the first organic material layer is utilized, so that the metal route layer can form the wrinkle structure; the preparation technology is simplified, the uniformity in bending of the metal routelayer is improved, and the problem of metal residues is solved when the wrinkle structure of the metal route layer is prepared by the etching technology and the like.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible display panel and the flexible display panel. Background technique [0002] At present, in the fan-out (sector) part of the flexible display panel, when the bending radius is less than 0.5mm, the metal wiring is easily broken. In the prior art, the following technical means are used to manufacture the metal wiring of the flexible display panel so as to prevent its breakage: firstly, all the inorganic films in the bending area are etched away, and then a hole is formed in the etched groove. layer of organic film. At this time, the organic film is patterned with a slot coating process, which can form a raised or depressed pattern on the surface of the film layer. When the flexible display panel is bent, it can relieve the stress to a certain extent and prevent the metal distribution of the sector. The effect of breaking the line. [0003] H...
