Flexible display panel and manufacturing method thereof

Abstract

The invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel comprises a substrate, an inorganic layer, an organic filling layer, source and drain electrode metal layer wires and a flat layer; the source and drain electrode metal layer wires comprise a first source and drain electrode metal layer wire located in a bending area and a second source and drain electrode metal layer wire located in a non-bending area, wherein the first source and drain electrode metal layer wire is a bent wire; and therefore, the source and drain metal layer wires are alternately subjected to pressure stress and tensile stress when the flexible display panel is bent, the neutralization offset of the pressure stress and the tensile stress can be realized, and thestress is reduced, so that the resistance change of the source and drain metal layer wires caused by the bending can be reduced, and optical change caused by the resistance change is reduced, and meanwhile, the risk of the breakage of the source and drain metal layer wires can be reduced, and the product performance of the flexible display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] In recent years, organic light-emitting diode (OLED) displays have attracted extensive attention and applications due to their advantages of high contrast, wide viewing angle, and bendability. The attention of consumers, as the technology becomes more and more mature, flexible and foldable display screens are gradually appearing in various booths. [0003] The flexible folding display needs to be rolled up or bent during use, or even bent frequently. As the number of bending increases, the line resistance of the source-drain metal layer wiring will easily increase, resulting in a decrease in the brightness of the display. As well as problems such as breakage of the source-drain metal layer wiring, causing poor display. [0004] To sum up, it is necessary to provide a new flexible display...

AI Technical Summary

Problems solved by technology

[0005] The flexible display panel and its manufacturing method provided by the present invention solve the problem that the existing flexible display panel tends to increase the line resistance of the source-drain metal layer wiring with the continuous increase of the number of bendings, resulting in a decrease in brightness and a problem of source-drain leakage. The technical problem of the breakage of the extremely metal layer wiring
