Embodiment Construction

[0028] The specific implementation manners of the flexible display substrate, the display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] A flexible display substrate provided by an embodiment of the present invention includes: a flexible substrate substrate, and wirings arranged in a fixed bending area on the flexible substrate substrate; wherein, such as Figure 2 to Figure 6 as shown,

[0030] The trace 001 is composed of a plurality of sequentially connected line segments 101;

[0031] Each line segment 101 has a set inclination angle θ with the extending direction D1 of the trace 001, and at least some of the line segments 101 have a hole-like structure 102;

[0032] There is a planar contact structure 103 between every two connected line segments 101 .

[0033] In the above-mentioned flexible display substrate provided by the embodiment of the prese...

Abstract

The invention discloses a flexible display substrate, a display panel and a display device. A line in a fixed bending area is formed by sequentially connecting multiple line segments, and the line segments have preset inclination angels with the line extending direction, so that bending stress on the line can be dispersed to the line segments; further, porous structures are arranged on at least part of the line segments, the bending stress dispersed to the line segments can be diffused to edge areas of the porous structures, the bending stress on the line is dispersed to the great extent, and therefore, the risk of fracture or breakage of the line in the fixed bending area is greatly reduced. Besides, a surface contact structure is formed between every two mutually connected line segments, so that multiple contact points are reserved between every two mutually connected line segments, even though fracture or breakage occurs at any contact point, connection of two adjacent line segments can still be realized through the other contact points, and the risk of fracture or breakage of the line is further reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display substrate, a display panel and a display device. 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] Display products with narrow borders have attracted a large number of consumers because they can enable users to obtain a better viewing experience, and have broad market prospects. In order to better respond to the market demand for narrow bezel display products, we have proposed a solution of pad bending (Pad Bending) on ​​the basis of flexible display panels, which greatly reduces the bezel of the driver end. However, if Figure 1a and Figure 1b As shown, due to the high brittleness of the inorganic insu...
