Flexible display panel with bending-resistant signal line

Abstract

A flexible display panel has a plurality of signal lines, at least one of which comprises a first metal layer, a first planar layer and a second metal layer. The first metal layer includes a pluralityof spaced apart metal pieces. The first flat layer is disposed on the first metal layer and includes a plurality of first through holes, and the first through hole positions correspond to the metal parts one by one to expose the metal parts. The second metal layer is disposed on the first flat layer, wherein the pattern shape of the second metal layer is a wavy shape, and the second metal layer is connected to the metal part through the first via hole.

Description

【Technical field】 [0001] The present invention relates to a flexible display panel, in particular to a flexible display panel with a bending-resistant signal line. 【Background technique】 [0002] Please refer to figure 1 As shown, in the existing flexible display panel, from the fan-out (fan-out) area to the operable area (Active area), there are GE metal lines 90 for transmitting signals in the horizontal direction, such as gate, reset, and light-emitting control; Signals in the direction include SE metal lines 91 such as data and power lines (ELVDD, ELVSS). [0003] The shape of the existing GE metal wire 90 or SE metal wire 91 is generally a long and thin rectangular shape, which cannot effectively relieve the stress and block the extension of the crack (Crack) when the display panel is bent. When the stress is greater than When the ability of the metal to bear, cracks are prone to occur, which will cause the impedance of the metal line to increase or break. The cracks...

Problems solved by technology

[0003] The shape of the existing GE metal wire 90 or SE metal wire 91 is generally a long and thin rectangular shape, which cannot effectively relieve the stress and block the extension of the crack (Crack) when the display panel is bent. When the metal bears the capacity, cracks are prone to occur, which will cause the impedance of the metal line to increase or break.

The cracks will further extend to other film layers or other functional areas during the folding process, which will increase the probability of adverse phenomena and shorten the service life of the device
