Embodiment 1

[0046] A flexible display panel provided by Embodiment 1 of the present invention, such as image 3 As shown, it includes: a flexible substrate substrate 301, a conductive layer 302 disposed on the display area A of the flexible substrate substrate, a plurality of wires 303 disposed on the edge bending region B of the flexible substrate substrate, and a plurality of wires 303 disposed on the conductive layer 302 and The inorganic insulating layer 304 between the multiple wires 303 and the flexible substrate 301; the conductive layer 302 is electrically connected to the multiple wires 303; in specific implementation, the flexible display panel may also include:

[0047]At least the first organic insulating layer 305 is disposed on the edge bending area B of the flexible substrate; and the first organic insulating layer 305 is located between the plurality of wires 303 and the inorganic insulating layer 304 . Wherein, the material of the first organic insulating layer 305 may be...

Embodiment 2

[0053] Since the structure of the flexible display panel provided by Embodiment 2 of the present invention is similar to that of the flexible display panel provided by Embodiment 1 of the present invention, only the flexible display panel provided by Embodiment 2 of the present invention and the flexible display panel provided by Embodiment 1 of the present invention are discussed here. The differences will be introduced, and the repetitions will not be repeated.

[0054] Specifically, unlike the first organic insulating layer 305 in the flexible display panel provided in the first embodiment of the present invention, which is only provided between the plurality of wires 303 and the inorganic insulating layer 304, the flexible display panel provided in the second embodiment of the present invention in, such as Figure 4 As shown, while the first organic insulating layer 305 is disposed between the plurality of wires 303 and the inorganic insulating layer 304, it can also be di...

Embodiment 3

[0057] Since the structure of the flexible display panel provided by the third embodiment of the present invention is similar to that of the flexible display panel provided by the second embodiment of the present invention, only the flexible display panel provided by the third embodiment of the present invention is compared with the flexible display panel provided by the second embodiment of the present invention. The differences will be introduced, and the repetitions will not be repeated.

[0058] Specifically, on the basis of the flexible display panel provided in the second embodiment of the present invention, in order to prevent the multiple traces 303 in the bending area B at the edge of the flexible substrate from being scratched, the above flexible display panel provided in the third embodiment of the present invention display panel, such as Figure 5 As shown, the second organic insulating layer 310 disposed at least at the edge bending area B of the flexible substrat...

Abstract

The invention discloses a flexible display panel, a display apparatus and a manufacturing method for the flexible display panel. The flexible display panel comprises a flexible substrate, a conductive layer which is arranged on a display region of the flexible substrate, a plurality of routing lines which are arranged on an edge bending region of the flexible substrate, and an inorganic insulating layer which is arranged among the conductive layer, the multiple routing lines and the flexible substrate; the conductive layer is electrically connected with the multiple routing lines; the flexible display panel also comprises a first organic insulating layer which is at least arranged in the edge bending region of the flexible substrate; and the first organic insulating layer is positioned between the multiple routing lines and the inorganic insulating layer. By virtue of the first organic insulating layer, expansion of cracks generated by the inorganic insulating layer to the multiple routing lines can be prevented, so that a phenomenon of display failure can be avoided; and in addition, compared with a technical scheme of adding two Mask processes in the prior art, the flexible display panel disclosed by the invention only needs to add one Mask process of manufacturing the first organic insulating layer, so that production cost is lowered while production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel, a display device and a method for manufacturing the flexible display panel. Background technique [0002] The display market is currently booming, and more new displays will emerge in the future as consumer demand continues to increase for a wide variety of display products such as laptops, smartphones, TVs, tablets, smart watches, and fitness wristbands product. [0003] Full-screen borderless display products can enable users to obtain a better viewing experience, and will surely detonate a new consumer market. Pad Bending is the core technology of full-screen borderless display products. However, if Figure 1a and Figure 1b As shown, due to the high brittleness of the inorganic insulating layer 101 , Pad Bending will cause a crack S to occur in the inorganic insulating layer 101 in the bending area of ​​the display product, and the crack ...
