Embodiment 1

[0027] Such as figure 1 Shown is a schematic structural diagram of Embodiment 1 of the flexible array substrate of the present invention. Wherein, the flexible array substrate includes a display area 10 and a bending area 20 located on one side of the display area 10, and the flexible array substrate also includes a first flexible substrate 11, a water-oxygen barrier layer 12, a second flexible substrate Bottom 13, buffer layer 14 and array structure layer;

[0028] The part of the array structure layer located in the display area 10 has a first source-drain wiring 111, the part of the array structure layer located in the bending area 20 has a second source-drain wiring, and the second The relative distance between the source-drain wiring and the buffer layer 14 is smaller than the relative distance between the first source-drain wiring 111 and the buffer layer 14 .

[0029] Specifically, the array structure layer also includes an active layer 15, a first gate insulating lay...

Embodiment 2

[0047] A flexible array substrate, such as image 3 As shown, the only difference from Embodiment 1 is that the second source-drain wiring 31 is located on the buffer layer 14 , the first gate insulating layer 16 and the second gate insulating layer 18 on any of the layers. The relative distance D3 between the second source-drain wiring 31 and the buffer layer 14 is smaller than the relative distance D1 between the first source-drain wiring 111 and the buffer layer 14 . Therefore, there is a certain height difference h2 between the source and drain traces of the flexible substrate located in the bending region 20 and the source and drain traces of the flexible substrate located in the display region 10 . The difference h2 can couple the stress between the flexible array substrate and the source-drain wiring, so that in the process of bending the flexible array substrate, the source-drain wiring located in the bending region of the flexible array substrate The stress received...

Embodiment 3

[0049] A flexible array substrate, such as Figure 4 As shown, the only difference from Embodiment 1 is that the second source-drain wiring 41 is located on the interlayer insulating layer 110 . The relative distance D4 between the second source-drain wiring 41 and the buffer layer 14 is smaller than the relative distance D1 between the first source-drain wiring 111 and the buffer layer 14 . Therefore, there is a certain height difference h3 between the source and drain traces of the flexible substrate located in the bending region 20 and the source and drain traces of the flexible substrate located in the display region 10 . The difference h3 can couple the stress between the flexible array substrate and the source-drain wiring, so that in the process of bending the flexible array substrate, the source-drain wiring located in the bending region of the flexible array substrate The stress received is small, the source and drain wires are prevented from being broken during the ...

Abstract

A flexible array substrate comprises a display area, a bending area located at one side of the display area, a first flexible substrate, a water and oxygen blocking layer, a second flexible substrate,a buffer layer and an array structure layer, wherein the part of the array structure layer, which is located in the display area, is provided with a first source and drain wire, the part of the arraystructure layer, which is located in the bending area, is provided with a second source and drain wire, and the relative distance between the second source and drain wire and the buffer layer is smaller than the relative distance between the first source and drain wire and the buffer layer.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible array substrate and a flexible display panel. Background technique [0002] With the development of mobile phone display technology, the requirements for mobile phone panels are getting higher and higher. Narrow bezels, high-profile ratios, and "chinless" mobile phone panels have become the goals pursued by most mobile phone panel suppliers and mobile phone manufacturers. In order to realize the above requirements of mobile phones, it is inseparable from the improvement of mobile phone panel manufacturing technology. In the prior art, the flexible array substrate is mainly provided with a bending area on one side of the display area, and the flexible array substrate is bent so as to be bent to the back of the flexible array substrate to reduce the bending radius. However, at present, after the flexible array substrate is bent, the metal traces on the flexibl...
