Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a display panel and display device. Background Technology

[0002] With the continuous development of display technologies such as Liquid Crystal Display (LCD), Organic Light Emitting Display (OLED), and Micro-Light Emitting Diode (Micro-LED), display panels are widely used in various industries. Improving the yield rate of display panel manufacturing has become one of the research directions for many manufacturers. Summary of the Invention

[0003] This application provides a display panel and display device that can improve the yield rate of manufactured products.

[0004] In a first aspect, embodiments of this application provide a display panel, which includes a display body, a first binding portion, a first bending portion, a second binding portion, and a second bending portion. The display body has a display area and a border area located around the display area. The display body includes a plurality of data lines extending along a first direction and arranged along a second direction, wherein the first direction and the second direction intersect.

[0005] The first bending portion is bent and connected between the first binding portion and the display body, and the first bending portion is located on the side of the bezel area away from the display area in the first direction. The second bending portion is bent and connected between the second binding portion and the display body, and the second bending portion is located on the side of the bezel area away from the display area in the second direction. The second binding portion includes a plurality of binding segments spaced apart in the first direction, and the second bending portion includes a plurality of bending segments spaced apart in the first direction, with different binding segments connected to different bending segments.

[0006] Secondly, based on the same inventive concept, embodiments of this application provide a display device, which includes the display panel in any of the foregoing embodiments.

[0007] This application provides a display panel and display device, which adjusts the structure of the second binding part and the second bending part. The second binding part is not a continuous and complete structure, but includes multiple binding portions spaced apart in a first direction. The second bending part includes multiple bending portions corresponding to and spaced apart from the multiple binding portions. In this way, when the second binding part is bent to the back of the display body, the multiple binding portions can be bent to the back of the display body through multiple bending operations using the multiple bending portions. Compared with the solution of bending the second binding part to the back of the display body in only one bending operation, this design can reduce the process difficulty of bending the second binding part to the back of the display body and improve the yield of the display panel.

[0013] With the advancement of science and technology, people's demands for display devices are increasing, and the need for narrower bezels on all four sides has surged. To further reduce the bezel size of display devices, three-sided bending display devices have emerged. Three-sided bending display devices refer to displays where not only the bottom bezel section but also sections of the left and right bezels are bent to the back, thus achieving an extremely narrow bezel effect on all four sides. However, bending the left and right bezel sections to the back presents greater technological challenges and is detrimental to yield rates.

[0014] Regarding the above issues, firstly, please refer to [link / reference needed]. Figure 1 and Figure 2 This application provides a display panel 100, which includes a display body 11, a first binding part 12, a first bending part 13, a second binding part 14, and a second bending part 15. The display body 11 has a display area 111 and a border area 112 located around the display area 111. The display body 11 includes a plurality of data lines 21 extending along a first direction X and arranged along a second direction Y, where the first direction X and the second direction Y intersect.

[0015] The first bending portion 13 is bent and connected between the first binding portion 12 and the display body 11, and the first bending portion 13 is located on the side of the border area 112 away from the display area 111 in the first direction X. The second bending portion 15 is bent and connected between the second binding portion 14 and the display body 11, and the second bending portion 15 is located on the side of the border area 112 away from the display area 111 in the second direction Y. The second binding portion 14 includes a plurality of binding portions 141 spaced apart in the first direction X, and the second bending portion 15 includes a plurality of bending portions 151 spaced apart in the first direction X. Different binding portions 141 and different bending portions 151 are connected and configured.

[0016] The display panel 100 is used in subsequent fabrication to form the display device 200. The display body 11 is the core area of ​​the display panel 100. The display body 11 includes a display area 111 and a border area 112. The display area 111 is the area in the display body 11 that realizes the light-emitting effect. The display panel 100 includes a light-emitting functional layer, and multiple light-emitting structures in the light-emitting functional layer are located within the display area 111. The border area 112 is the area in the display body 11 where peripheral wiring and circuit structures are placed, and the border area 112 surrounds the display area 111. Optionally, the shape of the border area 112 is adapted to the shape of the display area 111. For example, the display area 111 has a square shape, and the border area 112 has a square-ring shape.

[0017] The display body 11 is provided with a data line 21 for transmitting data signals. For example, the display body 11 also includes a pixel circuit. Multiple pixel circuits are arranged in the row and column directions and are respectively corresponding to multiple light-emitting structures. The pixel circuit can drive and control whether the light-emitting structure emits light. The data line 21 can provide data signals to the pixel circuit.

[0018] Data lines 21 extend along a first direction X, and multiple data lines 21 are arranged in a second direction Y. The first direction X is the column direction of the display panel 100, and the second direction Y is the row direction of the display panel 100. Optionally, the first direction X and the second direction Y are perpendicular to each other. The size of the display body 11 in the first direction X can be greater than, equal to, or smaller than its size in the second direction Y.

[0019] In some optional embodiments, the display body 11 also includes scan lines extending along the second direction Y, with multiple scan lines arranged in the first direction X. Further, multiple pixel circuits arranged in the second direction Y constitute a circuit row, and a single scan line is used to provide a scan signal to all or part of the pixel circuits in a single circuit row. Similarly, optionally, the display body 11 also includes light-emitting control lines. These light-emitting control lines also extend along the second direction Y, with multiple light-emitting control lines arranged in the first direction X.

[0020] The first bending portion 13 is used to realize the bending connection between the first binding portion 12 and the display body 11, and the second bending portion 15 is used to realize the bending connection between the second binding portion 14 and the display body 11. Both the first bending portion 13 and the second bending portion 15 are connected to the edge of the frame area 112 away from the display area 111. However, the difference is that the first bending portion 13 is connected to the side of the frame area 112 in the first direction X, and the second bending portion 15 is connected to the side of the frame area 112 in the second direction Y. Thus, the first binding portion 12 is a part of the display panel 100 located at the bottom frame and bent to the back, and the second binding portion 14 is a part of the display panel 100 located at the left frame and bent to the back.

[0021] In some alternative embodiments, the display panel 100 further includes a fourth bending portion 19 and a fourth binding portion 18. The fourth bending portion 19 is bent and connected between the fourth binding portion 18 and the display body 11, and the second bending portion 15 and the fourth bending portion 19 are located on both sides of the display body 11 in the second direction Y. In other words, the fourth binding portion 18 is a part of the display panel 100 located at the right frame and bent to the back.

[0022] Furthermore, the display device includes a display panel 100, a driver chip, and a circuit board structure, with the driver chip electrically connected to the first bonding portion 12. The circuit board structure includes a first circuit board and a second circuit board, with the first circuit board electrically connected to the first bonding portion 12 and the second circuit board electrically connected to the second bonding portion 14. Optionally, both the first circuit board and the second circuit board are flexible printed circuit boards (FPCs).

[0023] Since both the first binding part 12 and the second binding part 14 need to be bent to the back of the display body 11, compared with the related technology where only part of the structure at the bottom edge is bent to the back, the embodiment of this application requires bending at both the bottom edge and the left edge, which increases the difficulty of the process and is not conducive to the yield rate.

[0024] In view of this, the structure of the second binding part 14 and the second bending part 15 has been adjusted in this embodiment. The second binding part 14 is not a continuous and complete structure, but includes a plurality of binding portions 141 spaced apart in the first direction X. The second bending part 15 includes a plurality of bending portions 151 that correspond to and are spaced apart from the plurality of binding portions 141. In this way, when the second binding part 14 is bent to the back of the display body 11, the plurality of bending portions 151 can be bent independently to bend the plurality of binding portions 141 to the back of the display body 11 respectively. Compared with the scheme in which the second bending part 15 and the second binding part 14 are both continuous structures, this design can reduce the process difficulty of bending the second binding part 14 to the back of the display body 11 and improve the yield of the display panel 100.

[0025] It should be noted that the dimensional relationships between the multiple binding portions 141 are not limited in this embodiment. Different binding portions 141 may have the same size or different sizes in the first direction X. Similarly, different binding portions 141 may have the same size or different sizes in the second direction Y. Optionally, different binding portions 141 may have the same size in both the first direction X and the second direction Y, which can improve the structural consistency of the different binding portions 141.

[0026] The embodiments of this application do not impose limitations on the routing layout and the relationship between circuit structures within different binding sections 141. For example, the routing structures within different binding sections 141 are independent of each other, that is, the routing structure located in a single binding section 141 extends only into the display body 11 and does not extend into other binding sections 141, or some routing structures may extend through or into multiple binding sections 141.

[0027] The present application does not limit the relationship between the second circuit board and the multiple bonding portions 141. Optionally, multiple second circuit boards are provided, and the multiple second circuit boards are respectively connected and fixed to the multiple bonding portions 141. Alternatively, there is one second circuit board, and a single second circuit board is respectively connected and fixed to the multiple bonding portions 141.

[0028] Furthermore, for the fourth binding portion 18 and the fourth bending portion 19, optionally, the fourth binding portion 18 and the fourth bending portion 19 adopt a structural design similar to that of the second binding portion 14 and the second bending portion 15, that is, the fourth binding portion 18 also includes multiple segmented structures arranged at intervals. Further optionally, the fourth binding portion 18 and the second binding portion 14 are symmetrically arranged with respect to a virtual straight line parallel to the first direction X.

[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, the display body 11 includes a non-folding area A2 and a folding area A1, with the two non-folding areas A2 located on either side of the folding area A1 along the first direction X. When the second binding portion 14 is bent to the back of the display body 11 via the second bending portion 15, a gap space K exists between two adjacent binding portions 141. In the thickness direction Z of the display panel 100, the projection of the gap space K overlaps with the projection of the folding area A1. In other words, within the same projection plane perpendicular to the thickness direction Z of the display panel 100, there is an overlapping area between the orthographic projection of the gap space K and the orthographic projection of the folding area A1.

[0030] The display panel 100 provided in this embodiment is applied to a foldable display device. The display body 11 can be bent and deformed at the folding area A1 to switch the display panel 100 between a stowed state and a large-screen display state. In the stowed state, the folding area A1 is bent, and the non-folding areas A2 located on both sides of the folding area A1 are opposite each other in the thickness direction of the display panel 100. In the large-screen display state, the folding area A1 is flat, and the light-emitting surfaces of the two non-folding areas A2 in the display body 11 can be located in the same plane.

[0031] In this embodiment of the application, when the display panel 100 is actually used, the second binding part 14 will be bent to the back of the display body 11. At this time, the gap space K formed by the interval between the adjacent binding parts 141 can correspond to the folding area A1 in the thickness direction Z of the display panel 100. In this way, when the display panel 100 switches states, the display panel 100 will deform in the area corresponding to the gap space K, thereby reducing the risk of the binding part 141 and the bending part 151 being squeezed and deformed due to the state switching of the display panel 100, and improving the reliability of the display panel 100.

[0032] In some optional embodiments, the size of the gap space K in the first direction X is greater than or equal to the size of the folded area A1 in the first direction X in the large-screen display state. In this way, when the display panel 100 switches states, the binding portion 141 and the bending portion 151 can be completely offset from the deformation area of ​​the display panel 100, thereby further reducing the risk of the binding portion 141 and the bending portion 151 being squeezed and deformed, and improving the reliability of the display panel 100.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the dimension of the first bent portion 13 in the second direction Y is greater than or equal to the dimension of the single bent portion 151 in the first direction X.

[0034] This embodiment can be applied to situations where the size of the display body 11 in the first direction X is larger than its size in the second direction Y. In other words, the overall structure of the second bent portion 15 has a larger size in the first direction X than the size of the first bent portion 13 in the second direction Y. Based on this, if the second bent portion 15 maintains structural continuity in the first direction X, the deformation of the second bent portion 15 becomes more difficult, which is detrimental to the yield rate of the display panel 100.

[0035] However, in this embodiment, the second bending portion 15 is adjusted to include multiple bending segments 151 spaced apart, so that a portion of the structure of the display panel 100 at the left edge requires multiple bending operations. Furthermore, the dimension of a single bending segment 151 in the first direction X is set to be smaller than the dimension of the first bending portion 13 in the second direction Y, thereby reducing the process difficulty corresponding to a single bending operation. This design can improve the yield rate of the display panel 100.

[0036] In some embodiments, please refer to Figure 3 and Figure 4 The display panel 100 also includes a gate control circuit 30, which includes a plurality of shift registers 31. The gate control circuit 30 is located within the second bonding portion 14, and each bonding portion 141 includes at least one shift register 31. Figure 3 The fourth binding section 18 and the fourth bend section 19 are omitted, and only the wiring structure electrically connected to the shift register 31 within one of the binding sections 141 is shown.

[0037] It should be noted that in actual application of the display panel 100, the second bonding portion 14 needs to be bent to the back of the display body 11 via the second bending portion 15. However, to more clearly illustrate the gate control circuit 30 and some wiring structures, Figure 3 and Figure 4 The shape before the bending operation of the second bending portion 15 is shown.

[0038] The gate control circuit 30 is used to provide corresponding control signals to the pixel circuit. Specifically, the pixel circuit includes a transistor structure, and the gate control circuit 30 is used to provide corresponding gate control signals to the control terminals of the transistors in the pixel circuit. Optionally, the gate control signals include light emission control signals and scanning signals.

[0039] The gate control circuit 30 includes multiple cascaded shift registers 31. Cascading is a connection method in which the output of the previous shift register 31 is transmitted to the control terminal of the transistor in a specific pixel circuit to provide the corresponding gate control signal, and is also transmitted to the next shift register 31 as the signal input of that shift register 31.

[0040] Multiple gate control circuits 30 are provided. Different gate control circuits 30 can be used to output different control signals, or to output the same control signal to different pixel circuits. Optionally, the display body 11 is also provided with scan lines 22 and light emission control lines. The output terminal of the shift register 31 in some gate control circuits 30 is electrically connected to the scan line 22 to transmit scan signals to the scan line 22; the output terminal of the shift register 31 in some gate control circuits 30 is electrically connected to the light emission control line to transmit light emission control signals to the light emission control line.

[0041] The gate control circuit 30 is located within the second bonding portion 14. In actual application of the display panel 100, the gate control circuit 30 is located on the back of the display body 11. This design reduces the space occupied by the gate control circuit 30 in the bezel area 112, which is beneficial for achieving an extremely narrow bezel display effect. Multiple gate control circuits 30 can all be located within the second bonding portion 14, or some of the gate control circuits 30 can be located within the fourth bonding portion.

[0042] Furthermore, regarding the case where the second bonding section 14 includes multiple bonding subsections 141 spaced apart, this embodiment does not place all shift registers 31 in the gate control circuit 30 within the same bonding subsection 141. Instead, it distributes the multiple shift registers 31 across multiple bonding subsections 141, ensuring that each bonding subsection 141 includes at least one shift register 31. This allows the multiple shift registers 31 in the gate control circuit 30 to be arranged relatively dispersed, thereby alleviating the need for compact layout of different shift registers 31, improving the difficulty of wiring layout, and reducing signal interference between different shift registers 31.

[0043] It should be noted that the shift registers 31 located in different binding sections 141 can be cascaded together or set up independently. Specifically, the last-stage shift register 31 in a single binding section 141 can be cascaded with the first-stage shift register 31 in other adjacent binding sections 141, or the two can be set up in isolation. Here, "first-stage shift register 31" refers to the first shift register 31 in a single binding section 141 at the cascading connection level, while "last-stage shift register 31" refers to the last shift register 31 in a single binding section 141 at the cascading connection level.

[0044] In some alternative embodiments, the last-stage shift register 31 in a single bonding section 141 is isolated from the first-stage shift registers 31 in adjacent bonding sections 141. That is, the last-stage shift register 31 in a single bonding section 141 only outputs the gate control signal and does not provide cascaded signals to the first-stage shift registers 31 in other bonding sections 141. Based on this, the first-stage shift registers 31 in each bonding section 141 need to receive the start signal STV from the driver chip. With this design, if a shift register 31 in a single bonding section 141 malfunctions, it will not affect the normal operation of shift registers 31 in other bonding sections 141, thereby reducing the degree of display defects.

[0045] In other embodiments, such as Figure 3 and Figure 4 As shown, the plurality of bonding portions 141 include adjacent first bonding portions 141a and second bonding portions 141b, the plurality of bending portions 151 include a first bending portion 151a connected to the first bonding portion 141a and a second bending portion 151b connected to the second bonding portion 141b, and the gate control circuit 30 includes a first shift register 311 located in the first bonding portion 12 and a second shift register 312 located in the second bonding portion 141b.

[0046] The display panel 100 also includes a first connecting line 41, which includes a first connecting sub-line 411, a second connecting sub-line 412, and a third connecting sub-line 413. The first connecting sub-line 411 is electrically connected to the output terminal of the first shift register 311 and extends through the first bend portion 151a. The second connecting sub-line 412 is electrically connected to the input terminal of the second shift register 312 and extends through the second bend portion 151b. The third connecting sub-line 413 is electrically connected between the first connecting sub-line 411 and the second connecting sub-line 412 and is located within the display body 11.

[0047] The first binding portion 141a and the second binding portion 141b are two adjacent binding portions 141. The second binding portion 14 may include only the first binding portion 141a and the second binding portion 141b, or it may include other binding portions 141. This application embodiment does not limit this. The first bending portion 151a is connected between the first binding portion 141a and the display body 11, and the first binding portion 141a is bent to the back of the display body 11 through the first bending portion 151a. The second bending portion 151b is connected between the second binding portion 141b and the display body 11. The second binding portion 141b is bent to the back of the display body 11 through the second bending portion 151b.

[0048] The first shift register 311 and the second shift register 312 are two shift registers 31 located within adjacent, different binding portions 141 and cascaded together. Optionally, in the first direction X, the first binding portion 141a is located on the side of the second binding portion 141b away from the first bend portion 13, that is, the first binding portion 141a is farther away from the lower edge of the display panel 100 than the second binding portion 141b. Based on this, the first shift register 311 is the last-stage shift register 31 within the first binding portion 141a, while the second shift register 312 is the first-stage shift register 31 within the second binding portion 141b.

[0049] The first connection line 41 is a functional signal line cascading the first shift register 311 and the second shift register 312. Specifically, the first connection line 41 includes at least a first connection sub-line 411, a second connection sub-line 412, and a third connection sub-line 413. The first connection sub-line 411 transmits the output signal of the first shift register 311 and extends through the first bending section 151a. "Extending through the first bending section 151a" means that one end of the first connection sub-line 411 is located within the first binding section 141a, and the other end is located within the display body 11. Furthermore, before bending the first bending section 151a, the first connection sub-line 411 can extend along the second direction Y and pass through the first bending section 151a.

[0050] The second connecting sub-line 412 is used to input a signal to the second shift register 312 and extends through the second bending portion 151b. "Extending through the second bending portion 151b" means that one end of the second connecting sub-line 412 is located within the second binding portion 141b, and the other end is located within the display body 11. Furthermore, the second connecting sub-line 412 extends from the second binding portion 141b into the display body 11 through the second bending portion 151b. Further, before the bending operation is performed on the second bending portion 151b, the second connecting sub-line 412 can extend along the second direction Y and pass through the second bending portion 151b.

[0051] The third connecting sub-line 413 is electrically connected between the first connecting sub-line 411 and the second connecting sub-line 412. The output signal of the first shift register 311 is sequentially input into the second shift register 312 through the first connecting sub-line 411, the third connecting sub-line 413 and the second connecting sub-line 412, so as to realize the cascade connection of the first shift register 311 and the second shift register 312.

[0052] The third connecting sub-line 413 is located within the display body 11. Optionally, the third connecting sub-line 413 is located within the bezel area 112, which can reduce the adverse effects of the presence of the first connecting line 41 on the display effect. Further optionally, the third connecting sub-line 413 extends along the first direction X. When the second binding portion 14 bends to the back of the display body 11 through the second bending portion 15, the projection of the gap space K between the first binding portion 141a and the second binding portion 141b in the thickness direction Z of the display panel 100 overlaps with the projection of the third connecting sub-line 413.

[0053] In this embodiment, the first connecting line 41 includes a first connecting sub-line 411, a second connecting sub-line 412, and a third connecting sub-line 413. The first connecting sub-line 411 and the second connecting sub-line 412 are electrically connected to the first shift register 311 and the second shift register 312, respectively, and both extend through the corresponding bending portion 151 into the display body 11. The third connecting sub-line 413 is located inside the display body 11 and connects between the first connecting sub-line and the second connecting sub-line 412. By setting a portion of the structure in the first connecting line 41 within the display body 11, cascading between the first shift register 311 and the second shift register 312 in different binding portions 141 is achieved, satisfying the operational requirements of the gate control circuit 30. Furthermore, since the display body 11 only contains the wiring structure used to implement the cascading function, and does not contain circuit structures including the shift register 31, this reduces the space occupied by the bezel area 112, contributing to the achievement of an extremely narrow bezel display effect.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the gate control circuit 30 includes a third shift register 313 located within the first bonding portion 141a. The display panel 100 includes a first output signal line L1, which is electrically connected to the output terminal of the third shift register 313 and extends through the first bending portion 151a. At least a portion of the first output signal line L1 is disposed on the same layer as the first connecting sub-line 411, while the first connecting sub-line 411 and the third connecting sub-line 413 are disposed on different layers.

[0055] Both the third shift register 313 and the first shift register 311 are located within the first binding portion 141a. The third shift register 313 and the first shift register 311 can be directly cascaded, or other shift registers 31 can exist between them; this embodiment does not impose any limitations on this. The first output signal line L1 is electrically connected to the output terminal of the third shift register 313 and extends through the first bending portion 151a into the display body 11. Within the display body 11, the first output signal line L1 is electrically connected relative to one of the scan line 22 and the light emission control line to meet the transmission requirements of a specific signal.

[0056] It should be noted that the display panel 100 also includes a second output signal line L2, which is electrically connected to the output terminal of the first shift register 311 and is used to realize signal transmission between the first shift register 311 and the scan line 22 or the light emission control line. Based on this, the second output signal line L2 and the first connection line 41 can be two relatively independent trace structures, or as... Figure 4 As shown, a portion of the routing structure in the first connecting line 41 can also be reused as a portion of the routing structure in the second output signal line L2. For example, both the first connecting line 41 and the second output signal line L2 include a first connecting sub-line 411.

[0057] Similarly, the display panel 100 also includes a second connecting line, which is electrically connected to the output terminal of the third shift register 313. The second connecting line is used to realize the cascading between the third shift register 313 and the next-stage shift register 31. Based on this, the first output signal line L1 and the second connecting line can be two relatively independent routing structures, or part of the routing structure in the second connecting line can be multiplexed as part of the routing structure in the first output signal line L1.

[0058] Since both the first connecting sub-line 411 and the first output signal line L1 need to extend through the first bend portion 151a, and both can have the same extension trend, this embodiment of the application sets at least a portion of the first output signal line L1 on the same layer as the first connecting sub-line 411. For example, the portion of the routing structure of the first output signal line L1 located within the first bend portion 151a is set on the same layer as the portion of the first connecting sub-line 411 located within the first bend portion 151a, thereby reducing the difficulty of routing layout and mitigating the risk of different routing structures being affected by the bend in the first bend portion 151a.

[0059] As for the first connecting sub-line 411 and the third connecting sub-line 413, since they have different extension trends, the first connecting sub-line 411 and the third connecting sub-line 413 are located in different film layers to meet the extension requirements of the third connecting sub-line 413 along the first direction X, and to meet the avoidance requirements of the third connecting sub-line 413 relative to other lines in the frame area 112, which helps to make the internal wiring layout of the display panel 100 more reasonable.

[0060] In some alternative embodiments, please refer to Figure 5 The display panel 100 includes a substrate 91, a first conductor layer 92, a second conductor layer 93, and a third conductor layer 94. The first conductor layer 92, the second conductor layer 93, and the third conductor layer 94 are arranged sequentially in a direction away from the substrate 91. The portion of the first output signal line L1 located in the first bend portion 151a and the portion of the first connecting sub-line 411 located in the first bend portion 151a are both located in the third conductor layer 94.

[0061] As an example, the pixel circuit includes a first type transistor T1, a second type transistor T2, and a storage capacitor CST. The gate of the first type transistor T1 is located within a first conductive layer, and the two plates of the storage capacitor CST are located within a first conductive layer 92 and a second conductive layer 93, respectively. The gate of the second type transistor T2 is located within a third conductive layer 94. Specifically, the active structures of the first type transistor T1 and the second type transistor T2 are made of different materials. The active structure of the first type transistor T1 is made of low-temperature polycrystalline silicon, and the active structure of the second type transistor T2 is made of metal oxide. The active structure of the second type transistor T2 is located on the side of the active structure of the first type transistor T1 away from the substrate 91.

[0062] In some embodiments, such as Figure 3 and Figure 4As shown, the gate control circuit 30 includes a first shift register column 32 and a second shift register column 33 located within the same bonding portion 141. The first shift register column 32 and the second shift register column 33 are arranged along a second direction Y, and both include at least two shift registers 31 arranged in a first direction X. The gate control circuit 30 includes a first register 31a located within the first shift register column 32 and a second register 31b located within the second shift register column 33. At least a portion of the first register 31a and the second register 31b are cascaded.

[0063] The first shift register column 32 includes a plurality of first registers 31a arranged in the first direction X, and the second shift register column 33 includes a plurality of second registers 31b arranged in the first direction X. Both the first registers 31a and the second registers 31b are shift registers 31, and both are used to output the same type of gate control signal. The number of first registers 31a in the first shift register column 32 may be the same as or substantially the same as the number of second registers 31b in the second shift register column 33, or the number of the two may differ significantly.

[0064] It should be noted that when the first shift register column 32 includes three or more first registers 31a, the multiple first registers 31a can be set at equal intervals, or the distance between some adjacent first registers 31a can differ from the distance between other adjacent first registers 31a. Similarly, when the second shift register column 33 includes three or more second registers 31b, the multiple second registers 31b can be set at equal intervals, or the distance between some adjacent second registers 31b can differ from the distance between other adjacent second registers 31b.

[0065] Furthermore, from a cascading perspective, a single first register 31a can be cascaded with other adjacent first registers 31a, or it can be cascaded with a second register 31b. Similarly, a single second register 31b can be cascaded with other adjacent second registers 31b, or it can be cascaded with a first register 31a. This application embodiment does not impose any restrictions on this, as long as at least one first register 31a is cascaded with a second register 31b.

[0066] In this embodiment, the multiple shift registers 31 within a single binding section 141 are not arranged solely along the first direction X, but rather as a first shift register column 32 and a second shift register column 33 arranged along the second direction Y. Both the first shift register column 32 and the second shift register column 33 include at least two shift registers 31 arranged along the first direction X. This allows for a larger number of shift registers 31 to be placed in a single binding section 141 without altering the spacing between adjacent shift registers 31 in the same column along the first direction X. This satisfies the requirement for placing all shift registers 31 in the gate control circuit 30 within the second binding section 14, while simultaneously improving the narrow bezel effect of the display panel 100 and mitigating interference between different shift registers 31.

[0067] In some embodiments, such as Figure 3 and Figure 4 As shown, in the second direction Y, the first shift register column 32 is located on the side of the second shift register column 33 away from the bend portion 151. The display panel 100 also includes a first output line 42, which is electrically connected to the output terminal of the first register 31a. The first output line 42 extends through the second shift register column 33, and a portion of the first output line 42 is located between adjacent second registers 31b.

[0068] The first register 31a is electrically connected to the scan line 22 or the light emission control line via the first output line 42 to meet the transmission requirements of a specific signal. Since the first shift register column 32 is located on the side of the second shift register column 33 away from the bend portion 151, and the scan line 22 and the light emission control line are located inside the display body 11, the first output line 42 needs to extend through the second shift register column 33.

[0069] The phrase "extending through the second shift register column 33" refers to the following: a portion of the first output line 42 located within the second binding portion 14 lies on the side of the second shift register column 33 closer to the bending portion 151, another portion lies on the side of the second shift register column 33 away from the bending portion 151, and the remaining portion lies within the area of ​​the second shift register column 33 and is connected to the aforementioned two structural portions. Optionally, the wiring structure of the first output line 42 located within the second binding portion 14 extends along the second direction Y through the second shift register column 33.

[0070] In this embodiment, the first output line 42 extends through the second shift register column 33, and part of the first output line 42 is located between adjacent second registers 31b. This means that in the thickness direction Z of the display panel 100, the projection of the wiring structure in the second binding part 14 of the first output line 42 is located between the projections of adjacent second registers 31b. The projection of the first output line 42 does not overlap with the projection of the second register 31b, thereby reducing the interference of the signal in the first output line 42 on the second register 31b and improving the operational reliability of the gate control circuit 30.

[0071] In some alternative embodiments, at least a portion of the first output line 42 within the display area 111 includes a first segment extending along the second direction Y and a second segment extending along the first direction X, with the first segment and the second segment electrically connected. In other words, at least a portion of the first output line 42 can be electrically connected to the scan line 22 or the light-emitting control line using display area fan-out technology (FIAA). This design can reduce the space occupied by the first output line 42 in the bezel area 112, further improving the narrow bezel effect.

[0072] In some embodiments, such as Figure 3 and Figure 4 As shown, the first output line 42 includes a first output sub-line 421 and a second output sub-line 422. The first output sub-line 421 is electrically connected to the output terminal of the first register 31a and partially located between adjacent second registers 31b. The second output sub-line 422 is electrically connected to the first output sub-line 421 and extends through the bend portion 151. The first output sub-line 421 and the second output sub-line 422 are arranged on different layers. Figure 4 The first output sub-line 421 is shown in bold.

[0073] The first output sub-line 421 is a portion of the first output line 42 that extends through the second shift register column 33, and is located between adjacent second registers 31b. The second output sub-line 422 is a portion of the first output line 42 that extends through the bending section 151. The first output sub-line 421 can extend along the second direction Y, and before the bending operation is performed on the bending section 151, the second output sub-line 422 can also extend along the second direction Y; that is, the first output sub-line 421 and the second output sub-line 422 have the same extension trend.

[0074] Since the first output sub-line 421 and the second output sub-line 422 have the same extension trend and are connected, they are usually located in the same film layer. However, in this embodiment, since the first output sub-line 421 is located between adjacent second registers 31b, and in order to avoid interference between the first output sub-line 421 and other routing structures located between adjacent second registers 31b, the first output sub-line 421 and the second output sub-line 422 are located in different film layers. This reduces the interference of the first output sub-line 421 on other routing structures and improves the layout reliability of the routing structure.

[0075] In some embodiments, such as Figure 3 and Figure 4 As shown, at least a portion of the input and output terminals of the first register 31a are cascaded with the second register 31b, and at least a portion of the input and output terminals of the second register 31b are cascaded with the first register 31a.

[0076] Specifically, for at least a portion of the first registers 31a, their preceding shift register 31 and their following shift register 31 are different second registers 31b. For at least a portion of the second registers 31b, their preceding shift register 31 and their following shift register 31 are different first registers 31a. Further optionally, the distance between different adjacent first registers 31a in the first shift register column 32 can be kept consistent, and the distance between different adjacent second registers 31b in the second shift register column 33 can be kept consistent.

[0077] Taking pixel circuit D as an example, multiple pixel circuits D arranged in the second direction Y constitute circuit rows P, and multiple circuit rows P are arranged in the first direction X. The multiple circuit rows P include first circuit rows and second circuit rows. A first register 31a provides gate control signals to the first circuit rows, and a second register 31b provides gate control signals to the second circuit rows. Furthermore, the multiple first circuit rows and multiple second circuit rows are alternately arranged in the second direction Y; that is, there is one second circuit row between two closest first circuit rows, and one first circuit row between two closest second circuit rows.

[0078] For the cascaded first register 31a and second register 31b, their projections in the second direction Y can overlap, or their projections in the second direction Y can be completely staggered. Optionally, the projections of the first register 31a and the second register 31b in the second direction Y overlap. This design allows the cascaded first register 31a and second register 31b to be compactly arranged in the first direction X, meeting the placement requirements of multiple shift registers 31. On the other hand, it can reduce the extension length of the cascade line between them, thereby reducing the trace impedance of the cascade line.

[0079] In this embodiment, different shift registers 31 located in the same binding section 141 and cascaded are respectively located in different shift register columns. In this way, even if the projections of the different cascaded shift registers 31 in the second direction Y overlap, the normal operation of the two shift registers 31 will not be affected because the two shift registers 31 are spaced apart in the second direction Y. This takes into account the placement requirements of all shift registers 31 in the second binding section 14 and reduces the risk of interference between different shift registers 31.

[0080] In some embodiments, please refer to Figure 1 and Figure 6 The binding portion 141 includes a first edge E1 near the first bend portion 13 in the first direction X. Along the first direction X, in a single binding portion 141, the distance between the preceding shift register 31 and the first edge E1 is greater than the distance between the following shift register 31 and the first edge E1; and / or, along the second direction Y, in a single binding portion 141, the distance between the following shift register 31 and the bend portion 151 is greater than the distance between the preceding shift register 31 and the bend portion 151.

[0081] exist Figure 6 The diagram illustrates the relationships between multiple shift registers 31 using numerical representations. Specifically, the output of VSR1 is cascaded to the input of VSR2, and the output of VSR2 is cascaded to the input of VSR3. In other words, for VSR2, VSR1 is its upstream shift register 31, and VSR3 is its downstream shift register 31.

[0082] The first edge E1 is located at the end of the binding portion 141 near the lower edge of the display panel 100, that is, the first edge E1 is the lower edge of the binding portion 141. The "distance between the shift register 31 and the first edge E1" mentioned here refers to the distance between the center of the shift register 31 and the lower edge of the binding portion 141 in the first direction X.

[0083] In the display panel 100, the cascading relationship of shift registers 31 usually corresponds to the arrangement order of the corresponding circuit rows. Specifically, the previous shift register 31 usually provides the gate control signal to the previous circuit row, and the next shift register 31 usually provides the gate control signal to the next circuit row.

[0084] Therefore, in this embodiment, the cascading order of multiple shift registers 31 can be determined by referring to the distance between the shift register 31 and the lower edge of the binding section 141 to ensure that the attenuation trend of the cascaded signal is consistent with the driving direction corresponding to the multiple circuit rows, or by referring to the distance between the shift register 31 and the bending section 151. This design enables the cascading relationship of multiple shift registers 31 to be coordinated and unified with the arrangement order between the corresponding circuit rows, which is beneficial to realizing the electrical connection between the shift register 31 and the corresponding circuit rows.

[0085] It should be noted that, in this embodiment, a single binding segment 141 may include only the first shift register column 32 and the second shift register column 33, or it may include more shift register columns; this embodiment does not impose any limitations on this. Figure 6 The diagram shows a situation where a first shift register column 32, a second shift register column 33, and a third shift register column 34 exist simultaneously within the same binding section 141.

[0086] In some embodiments, please refer to Figure 7 and Figure 8 Multiple first registers 31a are cascaded together, and multiple second registers 31b are cascaded together. Specifically, the input of the first-stage second register 31b in the second shift register column 33 is cascaded with the first register 31a; and / or, the output of the last-stage second register 31b in the second shift register column 33 is cascaded with the first register 31a.

[0087] Specifically, for a portion of the first register 31a, its preceding shift register 31 and its following shift register 31 are different first registers 31a. For at least a portion of the second register 31b, its preceding shift register 31 and its following shift register 31 are different second registers 31b.

[0088] Taking pixel circuit D as an example, multiple circuit rows P include a first circuit row and a second circuit row. A first register 31a provides a gate control signal to the first circuit row, and a second register 31b provides a gate control signal to the second circuit row. Based on this, multiple first circuit rows are arranged adjacently to form a first circuit group, and multiple second circuit rows are arranged adjacently to form a second circuit group. The first circuit group is located on one side of the second circuit group in the first direction X.

[0089] In this configuration, the input of the first-stage second register 31b in the second shift register column 33 can be cascaded with the first register 31a, thereby placing the first-stage shift register 31 within the single-binding section 141 in the first shift register column 32. Alternatively, the first-stage second register 31b in the second shift register column 33 can also receive the start signal STV, thereby placing the first-stage shift register 31 within the single-binding section 141 in the second shift register column 33.

[0090] Similarly, the output of the last stage second register 31b in the second shift register column 33 can be cascaded with the first register 31a, so that the last stage shift register 31 in a single binding section 141 is located in the first shift register column 32, or the output of the last stage second register 31b in the second shift register column 33 can also be cascaded with the shift register 31 in other adjacent binding sections 141, so that the last stage shift register 31 in a single binding section 141 is located in the second shift register column 33.

[0091] In this embodiment, multiple shift registers 31 located in the same shift register column are cascaded together. This helps to reduce the cascade distance between different shift registers 31, thereby reducing the extension length of the cascaded traces between different shift registers 31 and reducing the interference of cascaded traces with other trace structures, thus improving the difficulty of trace layout in the bonding section 141.

[0092] In some embodiments, such as Figure 7 and Figure 8 As shown, the first shift register column 32 includes a first unit 321 and a second unit 322 spaced apart in the first direction X. Both the first unit 321 and the second unit 322 include at least two first registers 31a cascaded together. Within the same binding section 141, multiple shift registers 31 are cascaded sequentially along the order of the first unit 321, the second shift register column 33, and the second unit 322.

[0093] The "interval arrangement of the first unit 321 and the second unit 322" mentioned here refers to the fact that not all shift registers 31 in the first shift register column 32 are cascaded. Specifically, multiple first registers 31a in the first unit 321 are cascaded with each other, and multiple first registers 31a in the second unit 322 are cascaded with each other. However, the first register 31a in the first unit 321 that is closest to the second unit 322 and the first register 31a in the second unit 322 that is closest to the first unit 321 are not cascaded. Further optionally, along the first direction X, the distance between the first unit 321 and the second unit 322 is greater than the distance between adjacent first registers 31a in the first unit 321.

[0094] Multiple shift registers 31 are cascaded sequentially along the order of the first unit 321, the second shift register column 33, and the second unit 322. This means that the first-level shift register 31 in the binding section 141 is located in the first unit 321, the last-level shift register 31 in the binding section 141 is located in the second unit 322, and the last-level first register 31a in the first unit 321 is cascaded to the first-level second register 31b in the second shift register column 33, and the first-level first register 31a in the second unit 322 is cascaded to the last-level second register 31b in the second shift register column 33.

[0095] In some alternative embodiments, along the second direction Y, the first shift register column 32 is located on the side of the second shift register column 33 away from the second bend 15, the binding portion 141 includes a first edge E1 near the first bend 13 in the first direction X, and the second unit 322 is located on the side of the first unit 321 near the first edge E1. Further optionally, the first-stage first register 31a in the first unit 321 is located on the side of the remaining first registers 31a in the first unit 321 near the second unit 322, while the last-stage first register 31a in the second unit 322 is located on the side of the remaining first registers 31a in the second unit 322 near the first unit 321.

[0096] The number of first registers 31a in the first unit 321 and the second unit 322 is not limited in this embodiment. The number of first registers 31a in the first unit 321 can be greater than, equal to, or less than the number of first registers 31a in the second unit 322. Optionally, the number of first registers 31a in both the first unit 321 and the second unit 322 is less than the number of second registers 31b in the second shift register column 33. Further optionally, the sum of the number of first registers 31a in the first unit 321 and the second unit 322 is less than the number of second registers 31b in the second shift register column 33.

[0097] In this embodiment, the first shift register column 32 includes a first unit 321 and a second unit 322, which are respectively cascaded with the first-stage second register 31b and the last-stage second register 31b in the second shift register column 33. This allows more shift registers 31 to be placed in the first shift register column 32, rather than concentrated in the second shift register column 33, thereby improving the distance between adjacent second registers 31b in the second shift register column 33 and reducing the layout difficulty and interference of different shift registers 31 in the binding section 141.

[0098] In some embodiments, such as Figure 2 , Figure 7 and Figure 8As shown, the display body 11 includes a first area A3 and a second area A4. When the second binding part 14 is bent to the back of the display body 11 by the second bending part 15, a gap space K is formed between two adjacent binding parts 141. In the thickness direction Z of the display panel 100, the projection of the gap space K is located within the projection of the second area A4, and the projection of the first area A3 is located on the same side of the projection of all binding parts 141 in the first direction X.

[0099] The display panel 100 also includes a pixel circuit D. The output terminal of the first register 31a in the first unit 321 is electrically connected to the pixel circuit D in the first area A3, and the output terminal of the first register 31a in the second unit 322 is electrically connected to the pixel circuit D in the second area A4.

[0100] The first area A3 and the second area A4 of the display body 11 are arranged at intervals in the first direction X. A portion of the second area A4 corresponds to the gap space K. When the display panel 100 is subsequently formed into a foldable display device 200, the second area A4 is the folding area A1. Of course, in some other embodiments, the display panel 100 in this application embodiment can also be applied to a non-foldable display device 200.

[0101] In the thickness direction of the display panel 100, the projection of the first region A3 is located on the same side of all the bonding portions 141. The display body 11 may include two first regions A3, one located on the side of all the bonding portions 141 near the lower edge of the display body 11, and the other located on the side of all the bonding portions 141 near the upper edge of the display body 11. Optionally, both sides of the first region A3 in the second direction Y include arc-shaped segments, meaning the arc-shaped area within the border area 112 is located within the first region A3.

[0102] In this embodiment, the first register 31a in the first unit 321 is used to provide gate control signals to the pixel circuit in the first region A3, and the first register 31a in the second unit 322 is used to provide gate control signals to the pixel circuit in the second region A4. Based on this, the arc-shaped area within the first region A3 of the border area 112 does not require a shift register 31, and the straight area within the second region A4 of the border area 112 also does not require a shift register 31, thereby reducing the space occupied by the shift register 31 within the border area 112 and improving the narrow border effect.

[0103] In some alternative embodiments, the first register 31a in the first unit 321 and the pixel circuit D in the first area A3 can be electrically connected through FIAA technology, and the first register 31a in the second unit 322 and the pixel circuit D in the second area A4 can be electrically connected through FIAA technology. This design can further improve the narrow bezel effect.

[0104] In some optional embodiments, the display body 11 further includes a third region A5, which is connected between the first region A3 and the second region A4, and the projection of the bonding portion 141 in the thickness direction Z of the display panel 100 is located within the projection of the third region A5. The output terminal of the second register 31b in the second shift register column 33 is electrically connected to the pixel circuit within the third region A5.

[0105] In this embodiment, due to the presence of the first unit 321 and the second unit 322, the second register 31b in the second shift register column 33 only needs to provide gate control signals to the pixel circuits in the third region A5, without needing to provide gate control signals to the pixel circuits in the first region A3 and the second region A4. Based on this, there is no need to reduce the distance between adjacent second registers 31b in the second shift register column 33, thereby reducing interference between different second registers 31b and improving the operational reliability of the gate control circuit 30.

[0106] In some embodiments, please refer to Figure 9 The display panel 100 also includes a first signal line 50, which is electrically connected to the shift register 31. The first signal line 50 includes a first trace segment 511, a second trace segment 512, and a third trace segment 513. The first trace segment 511 extends along a first direction X and corresponds to the first shift register column 32. The second trace segment 512 extends along the first direction X and corresponds to the second shift register column 33. The third trace segment 513 extends along a second direction Y and connects the first trace segment 511 and the second trace segment 512.

[0107] The first signal line 50 is electrically connected to the shift register 31 to meet the operational requirements of the shift register 31. Optionally, the first signal line 50 is used to transmit one of the following: the start signal STV, the first clock signal CK, the second clock signal XCK, the low-voltage signal VGL, and the high-voltage signal VGH. Normally, each shift register 31 receives the first clock signal CK, the second clock signal XCK, the low-voltage signal VGL, and the high-voltage signal VGH. However, for the start signal STV, only the first-stage shift register 31 in the gate control circuit 30 receives the start signal STV.

[0108] Depend on Figure 9It can be seen that there is no necessary connection between the cascaded form of the gate control circuit 30 and the routing form of the first signal box 50. The first signal line 50 includes a first routing segment 511 corresponding to the first shift register column 32 and extending along the first direction X, and a second routing segment 512 corresponding to the second shift register column 33 and extending along the first direction X. The phrase "corresponding to the first shift register column 32" means that, in the thickness direction Z of the display panel 100, the projection of the first routing segment 511 overlaps with the projection of the first register 31a in the first shift register column 32; or the projection of the first routing segment 511 is adjacent to the projection of the first shift register column 32 in the second direction Y. Similarly, "corresponding to the second shift register column 33" means that: in the thickness direction Z of the display panel 100, the projection of the second trace segment 512 overlaps with the projection of the second register 31b in the second shift register column 33; or the projection of the second trace segment 512 and the projection of the second shift register column 33 are adjacent in the second direction Y.

[0109] The third trace segment 513 extends along the second direction Y and connects the first trace segment 511 and the second trace segment 512. The positional relationship of the third trace segment 513 relative to the first shift register column 32 and the second shift register column 33 is not limited in this embodiment. Optionally, in the thickness direction of the display panel 100, the projection of the third trace segment 513 is located on one side of the projections of the first shift register column 32 and the second shift register column 33 in the first direction X.

[0110] In this embodiment, the extension method of the first signal line 50 is not limited to the specific cascading form of the multiple shift registers 31. The first signal line 50 includes a first trace segment 511 and a second trace segment 512 extending along the first direction X and corresponding to the first shift register column 32 and the second register column, respectively, and a third trace segment 513 connecting the two trace segments. This can reduce the routing complexity of the first signal line 50, reduce the overall extension size of the first signal line 50, and improve the routing impedance of the first signal line 50 while reducing the routing layout difficulty.

[0111] In some embodiments, such as Figure 9 As shown, the first signal line 50 includes a first routing section 51 and a second routing section 52. Multiple first routing sections 51 are provided, and each binding section 141 contains a first routing section 51. Each first routing section 51 includes a first routing segment 511, a second routing segment 512, and a third routing segment 513. The second routing section 52 includes a fourth routing segment 521 and a fifth routing segment 522. The fourth routing segment 521 is connected to the second routing segment 512 and extends through the bending section 151. The fifth routing segment 522 is located within the display body 11 and its end along the first direction X is connected to the fourth routing segment 521.

[0112] The first wiring section 51 is a portion of the wiring structure within a single binding section 141 of the first signal line 50. The second wiring section 52 is used to connect adjacent different first wiring sections 51. The second wiring section 52 includes a fourth wiring segment 521 and a fifth wiring segment 522. The fourth wiring segment 521 extends through the bending section 151. Here, "extends through the bending section 151" means that one end of the fourth wiring segment 521 is located within the binding section 141 and connected to the second wiring segment 512, and the other end is located within the display body 11. Furthermore, before bending the bending section 151, the fourth wiring segment 521 can extend along the second direction Y and pass through the bending section 151.

[0113] Each second wiring section 52 includes two fourth wiring segments 521, which extend from adjacent different binding sections 141 into the display body 11, while a fifth wiring segment 522 is located within the display body 11 and connects the two fourth wiring segments 521. Optionally, the fifth wiring segment 522 is located within the border area 112 and extends along the first direction X.

[0114] In order to ensure that all shift registers 31 in different binding sections 141 are electrically connected to the first signal line 50, or to enable shift registers 31 located far from the driver chip to be electrically connected to the first signal line 50, the embodiments of this application provide that the first signal line 50 includes a first routing section 51 and a second routing section 52. By setting a portion of the structure in the second routing section 52 within the display body 11, the connection between different first routing sections 51 is achieved, thereby meeting the signal transmission requirements.

[0115] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, the same binding portion 141 includes opposing first edges E1 and second edges E2 in the first direction X. In the first direction X, the first edge E1 is located on the side of the second edge E2 closer to the first bend portion 13. Specifically, in the direction from the first edge E1 to the second edge E2, the number of shift registers 31 arranged in the second direction Y first decreases and then increases; and / or, the spacing between adjacent shift registers 31 first increases and then decreases.

[0116] As can be seen from the foregoing, the shift register 31, which provides gate control signals to the pixel circuits in the first region A3 and the second region A4, can be placed in the binding section 141, thereby reducing the size occupied by the bezel area 112 and improving the display effect of the narrow bezel.

[0117] Furthermore, the shift register 31 that provides gate control signals to the pixel circuit of the first region A3 is typically located in the bonding portion 141 near the edge region of the first region A3 in the first direction X, thereby reducing the extension length of the corresponding output signal line. Similarly, the shift register 31 that provides gate control signals to the pixel circuit of the second region A4 is typically located in the bonding portion 141 near the edge region of the second region A4 in the first direction X, thereby reducing the extension length of the corresponding output signal line.

[0118] In view of this, in the embodiment of this application, the number of shift registers 31 arranged in the second direction Y is set to decrease first and then increase in the direction from the first edge E1 to the second edge E2, or the spacing between adjacent shift registers 31 is set to increase first and then decrease, thereby increasing the distribution density of shift registers 31 in the edge region of the binding portion 141, making it greater than the distribution density of shift registers 31 in the center region of the binding portion 141, so as to match the placement requirements of shift registers 31 required by the pixel circuits in the first region A3 and the second region A4.

[0119] In some embodiments, please refer to Figure 10 The display panel 100 also includes touch signal lines 60 and touch electrodes 70. The touch electrodes 70 are located within the display body 11, and at least a portion of at least one touch signal line 60 is located within the bonding portion 141 and electrically connected to the touch electrode 70. Figure 10 The routing of the four touch signal lines 60 is shown in bold in the image.

[0120] The touch electrode 70 is the core component for realizing the touch function. Optionally, there are multiple touch electrodes 70, including touch transmitting electrodes and touch receiving electrodes. Further optionally, multiple touch transmitting electrodes are connected and arranged in the second direction Y, and multiple touch receiving electrodes are connected and arranged in the first direction X.

[0121] The touch signal line 60 is used to provide touch signals to the touch electrode 70. Optionally, the display device 200 includes a driver chip and a display panel 100. The driver chip is electrically connected to the first bonding part 12 and transmits touch signals to the touch signal line 60.

[0122] It should be noted that a single touch signal line 60 may extend into a single bonding portion 141, or it may extend into multiple bonding portions 141, or the touch signal line 60 may not extend into any bonding portion 141. This embodiment of the application does not impose any limitations on this. Optionally, the touch signal line 60 electrically connected to the touch receiving electrode may not extend into the bonding portion 141.

[0123] In this embodiment, the touch signal line 60 does not extend only through the bezel area 112. At least one part of the touch signal line 60 is located within the binding portion 141. Thus, at least one touch signal line 60 can extend through the binding portion 141, thereby reducing the space occupied by the touch signal line 60 in the bezel area 112 and further improving the narrow bezel effect of the display panel 100.

[0124] In some embodiments, such as Figure 10 As shown, the plurality of binding portions 141 include adjacent first binding portions 141a and second binding portions 141b, and the plurality of bending portions 151 include a first bending portion 151a connected to the first binding portion 141a, and a second bending portion 151b connected to the second binding portion 141b. In the first direction X, the first binding portion 141a is located on the side of the second binding portion 141b closer to the first bending portion 13. Figure 10 The driver chip IC is shown in the diagram using a dashed box.

[0125] At least one touch signal includes a first touch unit 61, a second touch unit 62, and a third touch unit 63. The first touch unit 61 extends from the first bonding portion 12 and the display body 11 into the first bonding portion 141a. The second touch unit 62 is partially located within the second bonding portion 141b and is electrically connected to the touch electrode 70. The third touch unit 63 is connected between the first touch unit 61 and the second touch unit 62. The third touch unit 63 includes a first touch sub-line 631, a second touch sub-line 632, and a third touch sub-line 633. The first touch sub-line 631 is connected to the first touch unit 61 and extends through the first bending portion 151a. The second touch sub-line 632 is connected to the second touch unit 62 and extends through the second bending portion 151b. The third touch sub-line 633 is connected between the first touch sub-line 631 and the second touch sub-line 632 and is located within the display body 11.

[0126] For the portion of the touch electrode 70 that is spaced a significant distance from the driver chip IC in the first direction X, the required touch signal line 60 can extend into multiple bonding portions 141. Specifically, at least one touch signal line 60 includes a first touch portion 61, a second touch portion 62, and a third touch portion 63. The first touch portion 61 is partially located within the first bonding portion 12 and connected to the driver chip. The first touch portion 61 extends sequentially from the first bonding portion 12, the first bending portion 13, the border area 112, and the first bending portion 151a into the first bonding portion 141a. The second touch portion 62 is partially located within the second bonding portion 141b. The second bonding portion 141b extends from the second bonding portion 141b and the second bending portion 151b into the display body 11 for electrical connection with the touch electrode 70. The third touch portion 63 is connected between the first touch portion 61 and the second touch portion 62 to realize the transmission of touch signals.

[0127] Furthermore, the third touch unit 63 includes a first touch sub-wire 631, a second touch sub-wire 632, and a third touch sub-wire 633. The first touch sub-wire 631 is connected to the first touch unit 61 and extends through the first bending portion 151a. "Extending through the first bending portion 151a" means that one end of the first touch sub-wire 631 is located within the first binding portion 141a, and the other end is located within the display body 11. The first touch sub-wire 631 extends into the display body 11 through the first binding portion 141a and the first bending portion 151a. Furthermore, before bending the first bending portion 151a, the first touch sub-wire 631 can extend along the second direction Y and pass through the first bending portion 151a.

[0128] The second touch sub-wire 632 is connected to the second touch unit 62 and extends through the second bending portion 151b. "Extending through the second bending portion 151b" means that one end of the second touch sub-wire 632 is located within the second binding portion 141b, and the other end is located within the display body 11. Furthermore, the second touch sub-wire 632 extends into the display body 11 through the second binding portion 141b and the second bending portion 151b. Further, before bending the second bending portion 151b, the second touch sub-wire 632 can extend along the second direction Y and pass through the second bending portion 151b.

[0129] The third touch sub-line 633 is located within the display body 11. Optionally, the third touch sub-line 633 is located within the bezel area 112, which can reduce the adverse effects of the presence of the third touch sub-line 633 on the display effect. Further optionally, the third touch sub-line 633 extends along the first direction X. When the second binding portion 14 bends to the back of the display body 11 through the second bending portion 15, the projection of the gap space K between the first binding portion 141a and the second binding portion 141b in the thickness direction Z of the display panel 100 overlaps with the projection of the third touch sub-line 633.

[0130] In this embodiment, at least one touch signal line 60 includes a first touch unit 61, a second touch unit 62, and a third touch unit 63. The first touch unit 61 and the second touch unit 62 are both partially located within the bonding portion 141, thereby reducing the space occupied by the first touch unit 61 and the second touch unit 62 in the bezel area 112 and improving the narrow bezel effect of the display panel 100. The third touch unit 63 is connected between the first touch unit 61 and the second touch unit 62 and is partially located within the display body 11. By extending a portion of the wiring structure within the third touch unit 63 into the display body 11, signal transmission between the first touch unit 61 and the second touch unit 62 is achieved, satisfying the need for touch signal transmission.

[0131] In some alternative embodiments, at least one touch signal line 60 includes a first touch portion 61 and a fourth touch portion. The first touch portion 61 extends from the first bonding portion 12 and the display body 11 into the first bonding portion 141a. The fourth touch portion is partially located in the first bonding portion 141a and electrically connected to the touch electrode 70. The first touch portion 61 and the fourth touch portion are electrically connected and disposed in the first bonding portion 141a.

[0132] In some embodiments, the width of the third touch sub-line 633 is smaller than the width of the first touch sub-line 631.

[0133] Combination Figure 10 Taking the second binding part 14 shown as an example where it is not bent to the back of the display body 11, the “width of the third touch sub-line 633” mentioned here refers to the size of the third touch sub-line 633 in the second direction Y, while the “width of the first touch sub-line 631” refers to the size of the first touch sub-line 631 in the first direction X.

[0134] For the first touch sub-line 631, a portion of its wiring structure is located within the first bonding portion 141a and the first bending portion 151a, with only a small portion located within the bezel area 112 of the display body 11. For the third touch sub-line 633, it is entirely located within the bezel area 112 of the display body 11, and all third touch sub-lines 633 among the multiple touch signal lines 60 extend along the first direction X and are arranged in the second direction Y. Therefore, the presence of the third touch sub-line 633 more readily occupies space in the bezel area 112, while the first touch sub-line 631 occupies a more limited amount of space in the bezel area 112.

[0135] In view of this, the width of the third touch sub-line 633 is adjusted to be smaller than the width of the first touch sub-line 631, thereby further reducing the space occupied by the touch signal line 60 in the bezel area 112 and improving the narrow bezel effect of the display panel 100.

[0136] In other embodiments, the width of the third touch sub-line 633 is equal to the width of the first touch sub-line 631. Adjacent third touch sub-lines 633 are disposed in different film layers, and the projections of adjacent third touch sub-lines 633 overlap in the thickness direction Z perpendicular to the display panel 100. This can also reduce its occupation of the space in the bezel area 112 and improve the narrow bezel effect of the display panel 100.

[0137] In some embodiments, please refer to Figure 10 and Figure 11 The third touch sub-line 633 includes at least two segmented structures 6331 stacked together, and the projections of the different segmented structures overlap in the thickness direction Z of the display panel 100. In other words, the third touch sub-line 633 is a double-layer metal structure, which is composed of metal structures located in different film layers connected in parallel.

[0138] In this embodiment, the third touch sub-line 633 is a double-layer metal structure. By projecting and overlapping different segment structures 6331 in the third touch sub-line 633 and setting them in parallel, the impedance of the third touch sub-line 633 can be reduced while the width of the third touch sub-line 633 is reduced, the space occupied by the third touch sub-line 633 in the bezel area 112 is reduced, and the narrow bezel effect of the display panel 100 is improved.

[0139] In some embodiments, please refer to Figure 12The display panel 100 also includes a third binding portion 16 and a third bending portion 17. The third bending portion 17 is bent and connected between the display body 11 and the third binding portion 16. The first bending portion 13 and the third bending portion 17 are located on opposite sides of the display body 11 in the first direction X. A plurality of binding portions 141 include adjacent first binding portions 141a and second binding portions 141b. In the first direction X, the first binding portion 141a is located on the side of the second binding portion 141b closer to the first bending portion 13.

[0140] The plurality of touch signal lines 60 include a first touch line 60a and a second touch line 60b, and the plurality of touch electrodes 70 include a first touch electrode 71 and a second touch electrode 72. The first touch line 60a extends from the first bonding portion 12 and the display body 11 into the first bonding portion 141a, and the first touch line 60a is electrically connected to the first touch electrode 71. The second touch line 60b extends from the third bonding portion 16 and the display body 11 into the second bonding portion 141b, and the second touch line 60b is electrically connected to the second touch electrode 72. The first touch electrode 71 is located on the side of the second touch electrode 72 near the first bending portion 13.

[0141] The first binding part 12 is a portion of the display panel 100 located at the lower edge and bent to the back, and the third binding part 16 is a portion of the display panel 100 located at the upper edge and bent to the back. Optionally, the first binding part 12 and the second binding part 14 have the same dimensions in the first direction X and the second direction Y.

[0142] Furthermore, the display device includes a display panel 100, a chip structure, and a circuit board structure. The chip structure includes a first driver chip IC1 and a second driver chip IC2. The first driver chip IC1 is electrically connected to a first bonding portion 12, and the second driver chip IC2 is electrically connected to a third bonding portion 16. The circuit board structure includes a first circuit board 300 and a third circuit board. The first circuit board 300 is electrically connected to the first bonding portion 12, and the third circuit board is electrically connected to the third bonding portion 16. Figure 12 The positional relationship between the first driver chip IC1 and the second driver chip IC2 and the display panel 100 is shown in the form of a dashed box.

[0143] by Figure 12 Taking the second binding portion 14 shown as an example, which only includes the first binding portion 141a and the second binding portion 141b, in the first direction X, the first binding portion 141a is relatively close to the first bending portion 13, that is, the first binding portion 141a is relatively close to the lower edge of the display body 11. The second binding portion 141b is relatively close to the third bending portion 17, that is, the second binding portion 141b is relatively close to the upper edge of the display body 11.

[0144] The plurality of touch electrodes 70 includes a first touch electrode 71 and a second touch electrode 72. In the first direction X, the first touch electrode 71 is relatively close to the first bending portion 13, and the second touch electrode 72 is relatively close to the third bending portion 17. The plurality of first touch electrodes 71 are arranged and electrically connected in the second direction Y, and the plurality of second touch electrodes 72 are arranged and electrically connected in the second direction Y. Optionally, when the second bonding portion 14 is bent to the back of the display body 11 via the second bending portion 15, in the thickness direction Z of the display panel 100, the projections of some of the first touch electrodes 71 overlap with the projection of the first bonding portion 141a, and the projections of some of the second touch electrodes 72 overlap with the projection of the second bonding portion 141b.

[0145] In view of this, the present application embodiment adds a corresponding third binding part 16 on the basis of the first binding part 12. In the subsequent manufacturing process of the display device 200, the first driving chip IC1 is electrically connected to the first binding part 12, the second driving chip IC2 is electrically connected to the third binding part 16, and the first touch electrode 71 is electrically connected to the first driving chip IC1 by means of the first touch line 60a, and the second touch electrode 72 is electrically connected to the second driving chip IC2 by means of the second touch line 60b. In this way, the first touch line 60a only needs to extend from the first bonding portion 12 and the display body 11 into the first bonding portion 141a, and the second touch line 60b only needs to extend from the third bonding portion 141 and the display body 11 into the second bonding portion 141b. This reduces the extension length of the first touch line 60a and the second touch line 60b, and both the first touch line 60a and the second touch line 60b only need to extend into a single bonding portion 141. This reduces the routing impedance of the first touch line 60a and the second touch line 60b, and reduces the space occupied by the touch signal line 60 in the bonding portion 141, thus reducing the difficulty of routing layout.

[0146] In some embodiments, such as Figure 10 As shown, the display panel 100 also includes a shielded signal line 80, which is at least partially located within the bonding portion 141. Figure 10 The three shielded signal lines 80 are shown in the diagram using thin lines.

[0147] The shielded signal line 80 is a wiring structure that provides shielding. A constant voltage signal can be transmitted within the shielded signal line 80. Optionally, to achieve the display's light-emitting function, a first power signal PVDD needs to be provided to the pixel circuit, and a second power signal PVEE needs to be provided to the cathode of the light-emitting structure. The shielded signal line 80 can transmit the second power signal PVEE. Alternatively, the shielded signal line 80 can also be used to transmit a ground signal GND or an isolation signal GU.

[0148] In some alternative embodiments, the display panel 100 includes a plurality of shielded signal lines 80, which are used to transmit a second power signal PVEE, a ground signal GND, and an isolation signal GU, respectively, and the plurality of shielded signal lines 80 are at least partially located within the bonding portion 141.

[0149] In this embodiment, in addition to the shift register 31 and the aforementioned wiring structure being located within the binding section 141, at least a portion of the shielded signal lines 80 can also be located within the binding section 141, thereby reducing the space occupied by the shielded signal lines 80 within the bezel area 112 and further improving the narrow bezel effect of the display panel 100.

[0150] In some alternative embodiments, at least one shielded signal line 80 includes a first shield, a second shield, and a third shield. The first shield is at least partially located within a first bonding portion 141a, the second shield is at least partially located within a second bonding portion 141b, and the third shield includes a first shield sub-wire, a second shield sub-wire, and a third shield sub-wire. The first shield sub-wire is connected to the first shield and extends through a first bend portion 151a, the second shield sub-wire is connected to the second shield and extends through a second bend portion 151b, and the third shield sub-wire is located within the display body 11 and connected between the first shield sub-wire and the second shield sub-wire.

[0151] In some embodiments, please refer to Figure 13 Within the bonding section 141, the shielded signal lines 80 and the touch signal lines 60 are arranged on the same layer, and multiple shielded signal lines 80 are distributed on both sides of the touch signal lines 60. Alternatively, please refer to... Figure 14 Within the bonding section 141, multiple shielded signal lines 80 and touch signal lines 60 are located on the same side of the substrate. In the thickness direction of the display panel 100, at least some of the shielded signal lines 80 and touch signal lines 60 overlap in projection.

[0152] Based on the foregoing, the shielded signal line 80 can be evenly located within the bonding portion 141. Furthermore, the shielded signal line 80 can be positioned close to the touch signal line 60 to shield the touch signal line 60 and enhance touch accuracy.

[0153] Furthermore, in this embodiment, the shielded signal line 80 and the touch signal line 60 can be arranged on the same layer, and multiple shielded signal lines 80 can be distributed on both sides of the touch signal line 60 to achieve the shielding function of the touch signal line 60. The shielded signal lines 80 located on both sides of the touch signal line 60 can transmit different signals or the same signal; this embodiment does not impose any limitation on this. Optionally, both sides of the touch signal line 60 are provided with a shielded signal line 80 for transmitting an isolation signal GU and a shielded signal line 80 for transmitting a ground signal GND, and the shielded signal line 80 for transmitting the ground signal GND is located on the side of the shielded signal line 80 for transmitting the isolation signal GU that is furthest from the touch signal line 60.

[0154] Alternatively, in this embodiment, the touch signal line 60 and the shielding signal line 80 within the bonding portion 141 can be arranged in different layers. The shielding signal line 80 is located on the side of the touch signal line 60 closer to the substrate, and the shielding signal line 80 overlaps with the touch signal line 60. In this way, the shielding signal line 80 can also shield the touch signal line 60, thereby enhancing touch accuracy.

[0155] Secondly, please refer to Figure 15 This application provides a display device 200, which includes the display panel 100 in any of the foregoing embodiments.

[0156] It should be noted that the display device 200 provided in this application embodiment has the beneficial effects of the display panel 100 in any of the foregoing embodiments. For details, please refer to the foregoing description of the beneficial effects of the display panel 100. This application embodiment will not repeat the description.

[0157] In some embodiments, such as Figure 15 As shown, the display device 200 also includes a first circuit board 300 and a second circuit board 400. The first circuit board 300 is electrically connected to the first bonding portion 12, and the second circuit board 400 is electrically connected to the second bonding portion 14. A single second circuit board 400 is welded and fixed to multiple bonding portions 141.

[0158] In this embodiment, multiple binding portions 141 are connected and fixed to the same second circuit board 400. This simplifies the connection process between the second binding portion 14 and the second circuit board 400, and allows a single second circuit board 400 to fix multiple binding portions 141, thereby improving the relative position reliability between different binding portions 141 and enhancing the stability of the display device 200.

[0159] It should be noted that during the manufacturing process of the display device 200, the circuit board is usually first connected and fixed to the bonding part, and then the bonding part is bent to the back side. However, in this embodiment, for the second bonding part 14 and the second circuit board 400, the plurality of bonding parts 141 are first bent to the back side, and then the second circuit board 400 is welded and fixed to the plurality of bonding parts 141. As for the first bonding part 12 and the first circuit board 300, the first circuit board 300 can be welded and fixed to the first bonding part 12 first, and then the first bonding part 12 can be bent to the back side, or the first bonding part 12 can be bent to the back side first, and then the first circuit board 300 can be welded and fixed to the first bonding part 12. This embodiment does not limit this.

[0160] While the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit the invention.
