[0039] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0040] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0041] The display panel of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can complement or be combined with each other.

[0042] like Figure 1 , Figure 2 and Fig.10 As shown, an embodiment of the present application provides a display panel 100 , which includes a display area 31 and a non-display area 32 located on at least one side of the display area 31 .

[0043] The display panel 100 includes a backplane layer 41, and in the direction from the display area 31 to the non-display area 32, the backplane layer 41 at least includes an anode wiring area D, a gate drive circuit wiring area H, and a cathode wiring area D1. A metal wire 10 is provided in the anode wiring area D, the gate drive circuit wiring area H, and the cathode wiring area D1. The metal wire 10 includes a plurality of pattern portions 11, and the pattern portions 11 are sequentially connected along the length direction of the metal wire 10. A recessed portion 12 is formed between each pattern portion 11 or between adjacent pattern portions 11. The pattern portion 11 and the recessed portion 12 are used to reduce stress concentration of the metal wire 10 when it is bent.

[0044] The non-display area 32 includes a bending area 321 , and part or all of the anode wiring area D, the gate driving circuit wiring area H, or the cathode wiring area D1 is located in the bending area 321 .

[0045] In order to reduce the width of the display panel frame and improve the user experience, the backplane layer 41 in the non-display area 32 of the display panel can be bent. The metal wires in the bending area of ​​the existing display panel are usually long and thin strip-shaped metal wires. When such metal wires are bent or folded, some stress concentration positions will appear on the metal wires, resulting in tiny cracks or deformations on the metal wires, or metal fatigue caused by stress concentration during long-term use, which can easily cause the metal wires to break, thereby affecting the normal display performance of the display panel.

[0046] The metal wire 10 used in the anode wiring area D, the gate drive circuit wiring area H and the cathode wiring area D1 of the backplane layer 41 in the present application includes a plurality of pattern portions 11. The plurality of pattern portions 11 can evenly distribute stress to prevent the stress on the metal wire from being too concentrated at certain positions, thereby preventing the metal wire 10 from cracking. At the same time, the recessed portion 12 can be used as a buffer position for stress release, which can absorb part of the stress and prevent the stress at certain positions on the metal wire 10 from being too concentrated, thereby enhancing the reliability of the metal wire 10. When part or all of the anode wiring area D, the gate drive circuit wiring area H and the cathode wiring area D1 are bent in the bending area 321, the metal wire 10 in the bending area 321 can maintain a normal connection state.

[0047] In one embodiment, Figure 1As shown, in the direction from the display area 31 to the non-display area 32, the backplane layer 41 sequentially includes the distance A from the display area to the initialization voltage wiring area, the initialization voltage wiring area B, the distance C from the initialization voltage wiring area to the anode wiring area, the anode wiring area D, the gate drive circuit wiring area H, the cathode wiring area D1, the distance E from the cathode wiring area to the screen crack detection wiring area, the screen crack detection wiring area F, and the distance G from the screen crack detection wiring area to the edge of the screen. The display panel can be bent at the anode wiring area D, the gate drive circuit wiring area H, and the cathode wiring area D1 to form a bending area, or bend at the anode wiring area D and the gate drive circuit wiring area H to form a bending area.

[0048] The width of the anode wiring area of ​​an existing display panel is 136 μm. The anode wiring area includes a first source drain layer and a second source drain layer. The first source drain layer and the second source drain layer can be respectively composed of three metal layers, namely, two titanium layers and an aluminum layer located between the two titanium layers. The thickness of the titanium layer ranges from The value range of aluminum layer is The width of the gate drive circuit wiring area of ​​the existing display panel is 1427 μm, including a first gate layer and a second gate layer. The materials of the first gate layer and the second gate layer can be molybdenum. The thickness of the first gate layer ranges from The thickness of the second gate layer ranges from

[0049] In one embodiment, according to Figure 2 The embodiment shown calculates the routing width of the bending zone 321, and the calculation formula for the routing width W of the bending zone is W=π*(bending radius R+bending zone thickness / 2)+reserved control area*2, wherein the bending radius R is 0.3mm, the bending zone thickness is the thickness of the portion of the backplane layer 41 located in the bending zone (0.024mm) plus the thickness of the back glue layer 42 (0.09mm), and the width of the reserved control area is 0.2mm. The calculated routing width W of the bending zone is 1522μm, which is equivalent to the width of the anode routing area of ​​136μm plus the width of the gate drive circuit routing area of ​​1427μm in the existing display panel.

[0050] In one embodiment, before the backplane layer 41 is bent, the width of the non-display area is 5 mm. After the backplane layer 41 is bent, Figure 2As shown, the width of the area 322 from the display area to the starting position of the bending area is 0.353mm, the bending radius R of the bending area 321 is 0.3mm, the thickness of the backplane layer 41 located in the area 322 is 0.049mm, the thickness of the backplane layer 41 located in the bending area is 0.024mm, the thickness of the adhesive layer 42 is 0.09mm, and the width of the entire non-display area 32 is 0.767mm, which is 4.333mm narrower than before the bending. It should be noted that the non-display area here only refers to the area of ​​the screen frame without the cover plate.

[0051] In one embodiment, Figure 1 As shown, the non-display area 32 is at least located on the left and right sides of the display area 31, and the anode wiring area D and the gate drive circuit wiring area H are located in the bending area 321. Figure 3 and Figure 4 As shown, the routing of the anode routing area D may use a metal wire 10 including a plurality of pattern portions 11, wherein the pitch Pitch of the metal wire 10 ranges from 5 μm to 300 μm. Figure 5 and Figure 6 As shown, the gate driving circuit wiring area H may also use a metal line 10 including a plurality of pattern portions 11 .

[0052] In some other embodiments, the non-display area 32 is not limited to being disposed on the left and right sides of the display area 31. Figure 7 As shown, the left and right sides of the display area 31 and the non-display area 32 at the bottom are provided with bending areas 321; Figure 8 As shown, the left and right sides of the display area 31 and the upper non-display area 32 are provided with bending areas 321; Fig. 9 As shown, bending areas 321 are provided on the left and right sides of the display area 31 and the upper and lower sides of the non-display area 32 .

[0053] In one embodiment, Figures 10 to 15 As shown, a hollow portion 13 is provided in the pattern portion 11, and the shape of the hollow portion 13 is the same as that of the pattern portion 11. The "same shape" here means that the outer contour of the hollow portion 13 is the same as that of the pattern portion 11. The hollow portion 13 can improve the elasticity of the metal wire 10. When the metal wire 10 is bent, the hollow portion 13 can be used as a stress release area to reduce the stress concentration on the metal wire. The shape of the hollow portion 13 matches the shape of the pattern portion 11, so that the stress can be more evenly distributed around the hollow portion 13, avoiding excessive local stress in the hollow portion 13, resulting in material fatigue or cracking. In some other embodiments, the shape of the hollow portion 13 may be different from that of the pattern portion 11. For example, when the shape of the pattern portion 11 is rectangular, the hollow portion 13 may be elliptical.

[0054] In one embodiment, partial regions of two adjacent pattern portions 11 overlap to form an overlapping portion 14. The overlapping portion 14 can disperse stress and reduce the stress borne by a single pattern portion 11. When the metal wire 10 is bent, the overlapping portion 14 can provide an additional stress point to avoid excessive stress concentration in other regions of the metal wire 10.

In the width direction of the metal wire, the first ends 111 of the two adjacent pattern portions 11 face opposite directions, the first end 111 is triangular, and stress can be guided to the recessed portion 12, the second end 112 is arc-shaped, and local stress concentration can be reduced, and the first end 111 and the second end 112 are alternately arranged, which can balance the stress distribution on the metal wire, enhance the reliability of the metal wire, and avoid the metal wire from breaking. In terms of signal transmission, the triangular first end 111 can reduce signal reflection and improve signal integrity, and the arc-shaped second end 112 is conducive to smooth transition of the signal and reduces signal distortion. The first end 111 and the second end 112 are arranged alternately, thereby improving the signal transmission characteristics.

[0056] exist Fig.10 and Fig.11 In the illustrated embodiment, the distance a between the second ends 112 of two adjacent pattern portions 11 in the width direction of the metal wire 10 ranges from 6 μm to 150 μm.

The pattern portion 11 is rectangular, and the rectangle has good structural stability and can resist deformation to a certain extent. The right angles and straight edges held can guide the uniform distribution of stress. The multiple pattern portions 11 are arranged obliquely, which can change the propagation direction of stress in the metal wire 10, which is conducive to dispersing stress and avoiding excessive concentration of stress in a specific direction of the metal wire 10. The inclined pattern portion 11 can also improve the flexibility of the metal wire 10 when bending.

The inclined arrangement of multiple pattern portions 11 can disperse the stress on the metal wire 10, reduce local stress concentration, and reduce the risk of breaking the metal wire 10.
