Embodiment 1

[0056] refer to image 3 , shows a schematic structural view of a flexible lining 20 provided by an embodiment of the present invention, the flexible lining 20 includes: a bending area 21 and support areas 22 on both sides of the bending area 21; refer to Figure 4 and Figure 5 ,for image 3 A cross-sectional view of the B-B direction of the middle bending area 21, wherein a plurality of hole structures 211 are arranged on the first surface a of the bending area 21; wherein, the openings of the hole structures 211 and the openings of the hole structures 211 The area of ​​the orthographic projection of the bottom on the first surface a is different; the orthographic projection of the opening of the hole structure 211 on the second surface of the bending region includes: a first straight line; the bottom of the hole structure is at The orthographic projection of the second surface of the bending area includes: a second straight line or point shape; the length of the first str...

Embodiment 2

[0091] In the embodiment of the present invention, refer to Figure 16 , shows a schematic structural view of a flexible liner provided by an embodiment of the present invention, the shape of the cross-section of the hole structure 211 parallel to the first plane a includes: a second drop shape. refer to Figure 18-Figure 21 ,for Figure 16 In the cross-sectional view of the F-F direction, the shape of the cross-section of the hole structure 211 perpendicular to the first plane a is the second rectangle.

[0092] refer to Figure 16 and Figure 18 , when the shape of the cross-section of the hole structure 211 parallel to the first plane a includes: the second drop shape, the hole structure 211 may be a hole structure with the same depth, refer to Figure 19 , can also be a through-hole; refer to Figure 20 and Figure 21 , it can also be a transition from a through hole in the middle area to a hole structure on both sides; wherein, from the middle area of ​​the bending ...

Embodiment 3

[0102] refer to Figure 19-Figure 21 , which shows that an embodiment of the present invention provides a flexible display panel, including the flexible liner 20 described in any one of the above.

[0103] Wherein, the flexible display panel further includes: a first adhesive material layer 30 ; a display function layer 40 ; a second adhesive material layer 50 and a cover plate 60 . Wherein, R is the bending radius of the flexible display panel.

[0104] refer to Figure 23 , which is a U-shaped inward folding of the flexible display panel. refer to Figure 24 , which is a U-shaped outward folding of the flexible display panel; refer to Figure 25 , the flexible display panel is inwardly folded in a drop shape.

[0105] In the embodiment of the present invention, refer to Figure 25 , two blank areas can be set in the bending area of ​​the flexible display panel, and the blank area does not need to be bent when the water-drop shape is folded inwardly, therefore, the hole...

Abstract

The embodiment of the invention provides a flexible lining plate and a flexible display panel. The flexible lining plate comprises a bending area and supporting areas on the two sides of the bending area. A plurality of hole structures are arranged on the first surface of the bending area; wherein the orthographic projection areas of the opening of the hole structure and the bottom of the hole structure on the first surface are different. In the embodiment of the invention, the area of the orthographic projection of the opening of the hole structure and the area of the orthographic projection of the bottom of the hole structure on the first surface are different, so that the area of the cross section of the hole structure parallel to the first surface is variable, the stress borne by the bending area can be better dispersed by the hole structure, and the service life of the bending area is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible backing board and a flexible display panel. Background technique [0002] In order to achieve the bending performance of the flexible display panel, a groove in the shape of a cube is usually provided in the bending area of ​​the flexible liner of the flexible display panel, refer to figure 1 , the flexible liner 10 is divided into a bending area 11 and a supporting area 12 , and a plurality of rectangular through holes 111 are arranged on the bending area 11 . refer to figure 2 ,for figure 1 In the cross-sectional view along the direction A-A, the cross-sectional shape of the through hole 111 is also rectangular. [0003] Since the current flexible lining is set as a through hole in the bending area, the strength of the bending area is reduced, and the flexible lining is at the boundary line X between the bending area and the support area, and there is a possibil...
