Description

Technical Field

[0001] The present disclosure relates to the field of display technologies, and in particular, to a display panel and a display device. Background Art

[0002] With the continuous development of science and technology, more and more display products, such as mobile phones, tablet computers, laptop computers, and smart wearable devices, etc., are widely used in people's daily lives and work, bringing great convenience to people's daily lives and work, and becoming an indispensable important tool for people today.

[0003] To implement the display function of a display product, signal lines for transmitting different signals are usually arranged in the display product. When signal coupling occurs between the signal lines transmitting different signals, stripes with a specific period may appear in the display screen, affecting the display effect. Therefore, how to improve the above problems has become one of the technical problems to be urgently solved at the present stage. Summary of the Invention

[0004] To solve the above technical problems, the present disclosure provides a display panel and a display device, aiming to reduce the coupling between different signals in the display product and improve the display effect.

[0006] In a second aspect, based on the same inventive concept, the present disclosure provides a display device including the display panel provided in the first aspect of the present disclosure.

[0007] The technical solutions provided in the embodiments of the present disclosure have the following advantages compared with the prior art:

The organic layer is, for example, a film layer in the display panel that plays a planarizing role and has a relatively large thickness. When the first type of connection line and the second type of connection line are at least isolated by the organic layer in the overlapping area, it is equivalent to increasing the distance between the first type of connection line and the second type of connection line in the overlapping area. When the first type of connection line and the second type of connection line in the overlapping area are respectively used as the two electrodes of a capacitor, the greater the distance between the two electrodes, the smaller the coupling capacitance between the two.

Therefore, it is beneficial to improve the overall display effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0039] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0040] Figure 1 A planar structure diagram of the display panel provided by the embodiment of the present disclosure is shown, Figure 1 Taking the display panel with a rectangular structure as an example for illustration, the actual shape of the display panel is not limited. In some other embodiments of the present disclosure, the display panel may also be embodied in other feasible shapes such as a circle, a rounded rectangle, etc. Optionally, the display panel provided in this embodiment may be a display panel adopting inorganic light-emitting diode display technology, that is, the light-emitting elements in the display panel may be Micro LED, Mini LED, etc. This type of display panel has advantages such as high brightness, low power consumption, and easy splicing, and is widely used in display products. The connection relationship of the light-emitting elements in the display panel may be appropriately referred to Figure 2 , Figure 2The following is a schematic diagram of a film layer of the display panel provided by the embodiments of the present disclosure. The light-emitting element LD is electrically connected to the pixel driving circuit 20 in the display panel. It should be noted that, Figure 2 only a film layer structure of the display panel is schematically shown, and the actual number and size of the film layers are not limited. For Figure 2 the detailed film layer structure will be described in the subsequent embodiments.

[0041] In some other embodiments of the present disclosure, the display panel may also be embodied as an organic light-emitting display panel, and the corresponding light-emitting element is an organic light-emitting element (such as OLED). The present disclosure does not specifically limit this.

[0042] It should be noted that, for clearly schematically showing the relative positional relationship of the gate driving circuit 10, the pixel driving circuit 20, the data line 30, and the first signal line 40, Figure 1 other structures of the display panel such as the light-emitting element LD are not shown in Figure 1 and only the pixel driving circuit 20 is schematically shown in a rectangular structure, and the number and arrangement manner of the pixel driving circuit 20 are not limited. In addition, Figure 1 the position of the gate driving circuit 10 in the display area in

[0043] Figure 3 is only for illustration. In some other embodiments of the present disclosure, the gate driving circuit 10 may also be disposed at other positions in the display area, which will be described in the subsequent embodiments. It should also be noted that, Figure 3 the connection relationship of the gate driving circuit 10 in the embodiments is only for illustration, and the present disclosure is not limited thereto.Figure 1 The embodiments are described by taking the case where the shift register is located between two adjacent rows of pixel driving circuits 20 as an example, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the shift register may also be located between two adjacent columns of pixel driving circuits 20.

[0044] Figure 4 As shown in Figure 1 FIG. is a partial enlarged schematic diagram of the wiring area A2 of the display panel and a part of the first area A1 adjacent to the wiring area A2. Please refer to Figure 1 and Figure 4 The embodiments of the present disclosure provide a display panel 100, including: a gate driving circuit 10, a pixel driving circuit 20, a data line 30, and a first signal line 40; the data line 30 is configured to provide a data signal to the pixel driving circuit 20, and the gate driving circuit 10 is configured to transmit a control signal to the pixel driving circuit 20. The control signals transmitted to the pixel driving circuit 20 include, for example, a reset control signal, a data writing control signal, a light emitting control signal, and the like. The first signal line 40 is electrically connected to the gate driving circuit 10 and is used to transmit a control signal to the gate driving circuit 10. The first signal line 40 may include, for example, Figure 3 at least one of the first clock signal line CK, the second clock signal line XCK, and the start trigger signal line STV shown in the schematic diagram. The control signals transmitted by the first signal line 40 to the gate driving circuit 10 include, for example, a clock signal, a start trigger signal, and the like. The display panel includes a first area A1 and a wiring area A2. The gate driving circuit 10 and the pixel driving circuit 20 are located in the first area A1, and the wiring area A2 is located on one side of the first area A1 close to the edge B of the display panel, so as to Figure 1 take as an example, the wiring area A2 is a region provided between the first area A1 and the lower edge B of the display panel. The wiring area A2 includes a first type of connection line 50 and a second type of connection line 60. The first type of connection line 50 is electrically connected to the data line 30, and the second type of connection line 60 is electrically connected to the first signal line 40. Optionally, a connection pad P0 is provided at a position in the wiring area A2 facing the lower edge of the display panel. Both the first type of connection line 50 and the second type of connection line 60 are electrically connected to the connection pad P0, so as to realize the electrical connection between the data line 30 and the first signal line 40 and the connection pad P0. In some other embodiments of the present disclosure, the connection pad P0 may be electrically connected to a control chip IC located on the back of the display panel through wiring on the upper side of the display panel to realize an extremely narrow border or borderless design of the display panel, but the present disclosure is not limited thereto. Of course, the connection pad P0 may also be directly bonded to the control chip or the flexible circuit board, and the present disclosure does not specifically limit this.

[0045] Please refer to Figure 4 and Figure 5, in a direction perpendicular to the plane where the light-emitting surface of the display panel is located, at least a part of the first type of connection line 50 and the second type of connection line 60 overlap to form an overlapping region Q0; in the overlapping region Q0, there is at least an organic layer 70 between the first type of connection line 50 and the second type of connection line 60, where, Figure 5 Shown as Figure 4 an AA-direction cross-sectional view of

[0046] Optionally, the display area of the display panel in the embodiments of the present disclosure includes the aforementioned first area A1, and the light-emitting elements are uniformly arranged in the first area A1. In some other embodiments of the present disclosure, the display area may also include the first area A1 and the wiring area A2 at the same time, and the light-emitting elements are uniformly arranged in the first area A1 and the wiring area A2.

[0047] Please refer to Figure 1 , Figure 4 and Figure 5 , when the gate driving circuit 10 is introduced into the display panel in the embodiments of the present disclosure, both the gate driving circuit 10 and the pixel driving circuit 20 are arranged in the first area A1, and the first area A1 belongs to the display area. The gate driving circuit 10 will not occupy the space of the non-display area. In this way, the non-display area may not be provided in the display panel, or only a non-display area with a smaller width needs to be provided, thereby facilitating the realization of a borderless or extremely narrow border design of the display panel.

[0048] Optionally, when the gate driving circuit 10 is set in the first area A1 in the embodiment of the present disclosure, the first signal line 40 connected to the gate driving circuit 10 is connected to the connection pad P0 through the second type of connection line 60 in the wiring area A2, and the data line 30 connected to the pixel driving circuit 20 is connected to the connection pad P0 through the first type of connection line 50 in the wiring area A2, and the first signal line 40 is interspersed between different data lines 30, and the first type of connection line 50 and the second type of connection line 60 overlap in the orthographic projection of the wiring area A2 and form an overlapping area Q0. Since the first type of connection line 50 is used to transmit data signals and the second type of connection line 60 is used to transmit clock signals or start trigger signals, the signals transmitted on the first type of connection line 50 and the second type of connection line 60 are both jumping signals. If the two are coupled, it will affect the normal display of the display panel. To this end, in the embodiment of the present disclosure, in the overlapping area of ​​the first type of connecting line 50 and the second type of connecting line 60, at least an organic layer 70 is spaced between the first type of connecting line 50 and the second type of connecting line 60. The organic layer 70 is, for example, a film layer that plays a flattening role in the display panel and has a relatively large thickness. When the first type of connecting line 50 and the second type of connecting line 60 are isolated by the organic layer 70 at least in the overlapping area, it is equivalent to increasing the distance between the first type of connecting line 50 and the second type of connecting line 60 in the overlapping area. When the first type of connecting line 50 and the second type of connecting line 60 in the overlapping area are respectively used as two plates of a capacitor, the greater the distance between the two plates, the smaller the coupling capacitance between the two will be, which is beneficial to reducing the coupling capacitance generated when the first type of connecting line 50 and the second type of connecting line 60 overlap, and is beneficial to weakening or eliminating the phenomenon of abnormal display stripes caused by the coupling capacitance, so it is beneficial to improve the overall display effect.

[0049] Figure 6 It is a schematic diagram of wiring of the first type of connection line 50 and the second type of connection line 60 in the wiring area A2. Figure 7 Shown Figure 6 For a BB' cross-section diagram, please refer to Figure 4 , Figure 6 and Figure 7 In an optional embodiment of the present disclosure, the second type of connecting line 60 includes a main body 61 and a connecting part 62 connected to the main body 61, and the connecting part 62 is located in the overlapping area Q0; along the direction perpendicular to the light emitting surface of the display panel, the connecting part 62 is located on the side of the organic layer 70 facing the light emitting surface, and the first type of connecting line 50 is located on the side of the organic layer 70 away from the light emitting surface.

[0050] In this embodiment, the connection portion 62 of the second type of connection line 60 is located in the overlapping region Q0, that is, the connection portion 62 overlaps with the first type of connection line 50. At this time, the connection portion 62 and the first type of connection line 50 are respectively arranged on both sides of the organic layer 70 along its thickness direction, and the connection portion 62 is made closer to the light-emitting surface of the display panel, while the first type of connection line 50 is made closer to the backlight surface of the display panel. Since both the first type of connection line 50 and the second type of connection line 60 ultimately need to be electrically connected to different connection pads P0, the film layer where the connection pads P0 are located is usually closer to the backlight surface of the display panel, that is, arranged on the side of the organic layer 70 away from the light-emitting surface of the display panel. Considering that the number of data lines 30 in the display panel is large and the number of the first type of connection lines 50 connected to the data lines 30 is also large, when the relatively large number of the first type of connection lines 50 is arranged on the side of the organic layer 70 facing the light-emitting surface of the display panel, the manufacturing process difficulty will increase when connecting this part of the first type of connection lines 50 to the connection pads P0 below the organic layer 70. Considering that the number of the first signal lines 40 in the display panel is small and the number of the second type of connection lines 60 connected to the first signal lines 40 is also small, even when the connection portion 62 arranged on the side of the organic layer 70 facing the light-emitting surface of the display panel is introduced into the second type of connection lines 60, the process of electrically connecting the relatively small number of connection portions 62 to the connection pads P0 is relatively simple. Therefore, in this embodiment, the way of arranging the connection portion 62 of the second type of connection line 60 on the side of the organic layer 70 facing the light-emitting surface and arranging the first type of connection line 50 on the side of the organic layer 70 away from the light-emitting surface is beneficial to reducing the coupling capacitance between the first type of connection line 50 and the second type of connection line 60 and simplifying the manufacturing process of the display panel.

[0051] It should be noted that the embodiments of the present disclosure are only described by taking the example that the first type of connection line 50 corresponding to the data line 30 is located on the side of the organic layer 70 away from the light-emitting surface of the display panel and the connection portion 62 in the second type of connection line 60 is located on the side of the organic layer 70 facing the light-emitting surface of the display panel, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the first type of connection line 50 corresponding to the data line 30 can also be arranged on the side of the organic layer 70 facing the light-emitting surface of the display panel, and the connection portion 62 in the second type of connection line 60 can be arranged on the side of the organic layer 70 away from the light-emitting surface of the display panel, which can also reduce the coupling capacitance between the first type of connection line 50 and the second type of connection line 60 and improve the overall display effect.

[0052] Please continue to refer to Figure 4 、 Figure 6 and Figure 7, in an alternative embodiment of the present disclosure, the main body portion 61 of the second type of connection line 60 is located on the side of the organic layer 70 away from the light-emitting surface. In this embodiment, the main body portion 61 in the second type of connection line 60 can be regarded as the part directly connected to the first signal line 40. The main body portion 61 does not overlap with the first type of connection line 50. The connection portion 62 is located on the side of the main body portion 61 facing the edge of the display panel. The connection portion 62 overlaps with the first type of connection line 50. Therefore, the connection portion 62 is equivalent to a jumper to the side of the organic layer 70 facing the light-emitting surface relative to the main body portion 61 to reduce the coupling capacitance with the first type of connection line 50. Considering that the first signal line 40 connected to the main body portion 61 may be located on the side of the organic layer 70 away from the light-emitting surface of the display panel, that is, below the organic layer 70, when the main body portion 61 directly connected to the first signal line 40 is arranged on the side of the organic layer 70 away from the light-emitting surface, it is beneficial to reduce the connection difficulty between the main body portion 61 and the first signal line 40.

[0053] Please continue to refer to Figure 4 and Figure 6 , in an alternative embodiment of the present disclosure, the main body portion 61 of the second type of connection line 60 is arranged on the same layer as the first signal line 40. In this way, the main body portion 61 and the first signal line 40 can be fabricated and connected in the same process. Compared with the solution that two fabrication processes are required and vias need to be introduced for connection when the main body portion 61 and the first signal line 40 are arranged in different film layers, the solution of arranging the main body portion 61 and the first signal line 40 connected thereto on the same layer in this embodiment is beneficial to simplifying the fabrication process and improving production efficiency.

[0054] The above embodiments illustrate the solution of arranging the main body portion 61 and the connection portion 62 of the second type of connection line 60 on the side of the organic layer 70 away from the light-emitting surface and the side facing the light-emitting surface respectively. In some other embodiments of the present disclosure, the main body portion 61 and the connection portion 62 of the second type of connection line 60 can also be arranged on the side of the organic layer 70 facing the light-emitting surface of the display panel. For example, please refer to Figure 8 and Figure 9 , Figure 8 shows another wiring schematic diagram of the first type of connection line 50 and the second type of connection line 60 in the wiring area A2. Figure 9 shows Figure 8 a cross-sectional view taken along the CC' direction of

[0055] When both the main body portion 61 and the connecting portion 62 of the second type of connecting line 60 are disposed above the organic layer 70, that is, on the side of the light-emitting surface of the organic layer 70 facing the display panel, there is no longer a relatively thick organic layer 70 between the main body portion 61 and the connecting portion 62. Therefore, it is beneficial to simplify the connection difficulty between the main body portion 61 and the connecting portion 62. Optionally, in this embodiment, the first signal line 40 may also be disposed on the side of the light-emitting surface of the organic layer 70 facing the display panel. For example, it may be disposed on the same layer as the main body portion 61, thereby facilitating the simplification of the overall manufacturing process of the first signal line 40 and the main body portion 61 and simplifying the connection between the two.

[0056] Please continue to refer to Figure 8 and Figure 9 , when both the main body portion 61 and the connecting portion 62 in the second type of connecting line 60 are disposed on the side of the light-emitting surface of the organic layer 70 facing the display panel, in an alternative embodiment of the present disclosure, the connecting portion 62 is located on the side of the main body portion 61 facing the light-emitting surface. That is to say, compared with the main body portion 61, the distance between the connecting portion 62 and the organic layer 70 is greater. Considering that the connecting portion 62 overlaps with the first type of connecting line 50, and the first type of connecting line 50 is located on the side of the organic layer 70 away from the light-emitting surface of the display panel, therefore, in this embodiment, when the connecting portion 62 in the second type of connecting line 60 is disposed on the side of the main body portion 61 away from the organic layer 70, it is beneficial to increase the longitudinal distance between the connecting portion 62 and the first type of connecting line 50, thereby further reducing the signal coupling between the first type of connecting line 50 and the second type of connecting line 60 and further weakening or eliminating the display stripes caused by signal coupling.

[0057] When both the main body portion 61 and the connecting portion 62 in the second type of connecting line 60 are disposed on the side of the light-emitting surface of the organic layer 70 facing the display panel, the above embodiment shows a solution in which the main body portion 61 and the connecting portion 62 are disposed in different film layers. In some other embodiments of the present disclosure, the main body portion 61 and the connecting portion 62 in the second type of connecting line 60 may also be disposed in the same film layer. For example, please refer to Figure 10 and Figure 11 , Figure 10 shows another wiring schematic diagram of the first type of connecting line 50 and the second type of connecting line 60 in the wiring area A2, Figure 11 shows Figure 10 a cross-sectional view taken along the DD' direction of, in an alternative embodiment of the present disclosure, the main body portion 61 of the second type of connecting line 60 is disposed on the same layer as the connecting portion 62. In this way, the main body portion 61 and the connecting portion 62 in the second type of connecting line 60 can be fabricated in the same manufacturing process, and there is no need to use vias to connect the two, thereby facilitating the simplification of the manufacturing process of the second type of connecting line 60.

[0058] It should be noted that the specific film layer structures of the main body portion, the connection portion in the second type of connection line and the first type of connection line in the foregoing embodiments are only illustrative, and the present disclosure is not limited thereto.

[0059] Figure 12 Another wiring schematic diagram of the first type of connection line 50 and the second type of connection line 60 in the wiring area A2 is shown. Figure 13 As shown Figure 12 is a cross-sectional view taken along the EE' direction. Please refer to Figure 1 , Figure 12 and Figure 13 , in an alternative embodiment of the present disclosure, the second type of connection line 60 includes a main body portion 61 and a lead-out portion 63 connected to the main body portion 61. The lead-out portion 63 is located on the side of the organic layer 70 away from the light-emitting surface, and the lead-out portion 63 is located on the side of the main body portion 61 close to the edge B of the display panel. It should be noted that for the main body portion 61 and the lead-out portion 63 connected to the main body portion 61 mentioned in the embodiments of the present disclosure, they can be directly connected or connected through other connection structures. In this embodiment, the scheme is that the main body portion 61 and the lead-out portion 63 are connected through a connection portion 62, but the present disclosure is not limited thereto.

[0060] Please refer to Figure 1 , Figure 12 and Figure 13 , the lead-out portion 63 in the second type of connection line 60 can be regarded as an intermediate component connected to the connection pad P0 in the display panel. The film layer where the connection pad P0 is located is usually on the side of the organic layer 70 away from the light-emitting surface of the display panel, that is, below the organic layer 70, or there is no organic layer at the position where the connection pad P0 is located; to reduce or avoid the coupling capacitance between the first type of connection line 50 and the second type of connection line 60, the present disclosure sets at least the overlapping portion of the second type of connection line 60 with the first type of connection line 50 on the side of the organic layer 70 facing the light-emitting surface of the display panel. At this time, to realize the connection between the second type of connection line 60 and the connection pad P0, it is necessary to lead out the line segment of the second type of connection line 60 arranged on the side of the organic layer 70 facing the light-emitting surface to the side of the organic layer 70 away from the light-emitting surface. Therefore, the second connection line segment in this embodiment further includes a lead-out portion 63, which is located on the side of the organic layer 70 away from the light-emitting surface. One end of the lead-out portion 63 can be connected to the line segment of the second connection line arranged on the side of the organic layer 70 facing the light-emitting surface through a via, and the other end is connected to the connection pad P0, thereby realizing the electrical connection between the second connection line segment and the connection pad P0 through the lead-out portion 63.

[0061] Figure 14Shown is another wiring schematic diagram of the first type of connecting line 50 and the second type of connecting line 60 in the wiring area A2. In an alternative embodiment of the present disclosure, the second type of connecting line 60 includes an opening K, and along the direction perpendicular to the plane where the light-emitting surface of the display panel is located, the opening K overlaps with the overlapping area between the first type of connecting line 50 and the second type of signal line 60. When the first type of connecting line 50 and the second type of connecting line 60 overlap, in this embodiment, an opening K is formed on the second type of connecting line 60. The opening K penetrates the second type of connecting line 60 in the thickness direction of the second type of connecting line 60, and the opening K is at least located in the overlapping area between the first type of connecting line 50 and the second type of connecting line 60. In this way, it is beneficial to reduce the actual overlapping area of the first type of connecting line 50 and the second type of connecting line 60 in the overlapping area. By reducing the actual overlapping area of the two, it is beneficial to further reduce the coupling capacitance between the two, thereby being beneficial to further reducing or eliminating the problem of abnormal display stripes caused by the influence of the coupling capacitance.

[0062] It should be noted that Figure 14 only an example of a way to set the opening K on the second type of connecting line 60 is given, and the number, size, and shape of the actual opening K set on the second type of connecting line 60 are not limited. Moreover Figure 14 only when the second type of connecting line 60 includes a main body portion 61 and a connecting portion 62 arranged in different layers, and only the example of setting the opening K on the connecting portion 62 overlapping with the first type of connecting line 50 is given. When the main body portion 61 and the connecting portion 62 in the second type of connecting line 60 are arranged in the same layer, the opening K can also be set on the connecting portion 62 overlapping with the first type of connecting line 50. Moreover, regardless of which film layer the connecting portion 62 in the second type of connecting line 60 is located in, the actual overlapping area between the second type of connecting line 60 and the first type of connecting line 50 can be reduced by setting the opening K.

Along the direction perpendicular to the plane where the light-emitting surface of the display panel is located, the shielding portion 90 is located between the first type of connecting line 50 and the second type of connecting line 60, and the shielding portion 90 receives a fixed potential signal.

[0064] In the present disclosure, in the overlapping area Q0, the scheme of arranging the first type of connection line 50 and the second type of connection line 60 on both sides of the organic layer 70 along the thickness direction thereof respectively increases the distance between the first type of connection line 50 and the second type of connection line 60 in the overlapping area, which is beneficial to reduce the coupling capacitance formed between the first type of connection line 50 and the second type of connection line 60. On this basis, in the present embodiment, a shielding part 90 is further introduced between the first type of connection line 50 and the second type of connection line 60 in the overlapping area Q0, and the shielding part 90 that receives the fixed potential signal shields the signals of the first type of connection line 50 and the second type of connection line 60, so as to avoid the coupling of the signals of the first type of connection line 50 and the second type of connection line 60 to form a coupling capacitance, thereby facilitating the elimination of the coupling capacitance generated by the overlap of the first type of connection line 50 and the second type of connection line 60, so as to avoid the problem of abnormal display stripes caused by the influence of the coupling capacitance, and thus more beneficial to improving the display effect of the display panel.

[0065] It should be noted that the fixed potential signal received by the shielding portion 90 may be a fixed potential signal originally existing in the display panel, such as a fixed high level signal or a fixed low level signal, etc., thereby eliminating the need to introduce new signals into the shielding portion 90, which is conducive to simplifying the design of the display panel.

The corresponding film layer diagram can be referred to Figure 15 , please combine Figure 15 and Figure 16 In an optional embodiment of the present disclosure, the second type of connecting line 60 includes a main body 61, and the main body 61 overlaps with the first type of connecting line 50 along a direction perpendicular to the plane where the light emitting surface of the display panel is located, and the shielding part 90 covers the main body 61.

[0067] This embodiment shows a scheme in which the main body 61 in the second type of connection line 60 overlaps with the first type of connection line 50, and the main body 61 is located on the side of the light-emitting surface of the organic layer 70 facing the display panel. In order to realize the electrical connection between the second type of connection line 60 and the connection pad P0, the second type of connection line 60 may further include a lead-out portion 63, and the lead-out portion 63 is located on the side of the organic layer 70 away from the light-emitting surface of the display panel, and the main body 61 in the second connection line can realize the electrical connection with the connection pad P0 through the lead-out portion 63. In this embodiment, when the shielding portion 90 covers the main body 61, the shielding portion 90 can be regarded as a planar structure arranged in the wiring area A2, so that the coverage of the shielding portion 90 is larger, and the shielding effect of the signal between the first type of connection line 50 and the second type of connection line 60 is better.

[0068] Please combine Figure 1 and Figure 2In an optional embodiment of the present disclosure, the display panel includes a first metal layer M1, a capacitor metal layer MC, and a second metal layer M2 located on the side of the organic layer 70 away from the light emitting surface, and a third metal layer M3 and a fourth metal layer M4 located on the side of the organic layer 70 facing the light emitting surface, wherein the capacitor metal layer MC is located between the first metal layer M1 and the second metal layer M2, and the second metal layer M2 is located on the side of the capacitor metal layer MC facing the organic layer 70, and the fourth metal layer M4 is located on the side of the third metal layer M3 away from the organic layer 70. The first area A1 of the display panel includes a plurality of transistors T, the gate of the transistor may be located in the first metal layer M1, and the source and drain may be located in the second metal layer M2, in the first area A1 of the display panel, the first metal layer M1 and the second metal layer M2 may also be provided with a plurality of signal lines, and similarly, the third metal layer M3 and the capacitor metal layer MC may both be used for the layout of signal lines. The capacitor metal layer MC is also used to overlap with the second metal layer M2 or the first metal layer M1 to form a storage capacitor in the pixel driving circuit 20. Optionally, a pad connected to an electrode of the light emitting element may be located on the fourth metal layer M4.

[0069] In the wiring area A2, the first type of connecting line 50 is located on the side of the organic layer 70 away from the light-emitting surface of the display panel. Specifically, the first type of connecting line 50 can be located on the first metal layer M1 and / or the capacitor metal layer MC. Optionally, the display panel may also include an auxiliary metal layer M0 arranged on the side of the first metal layer M1 away from the organic layer 70, and the auxiliary metal layer M0 overlaps with the channel region of the transistor to play a light-shielding role to prevent light from affecting the transistor. When the display panel includes the aforementioned auxiliary metal layer M0, optionally, the first type of connecting line 50 may also be located in the auxiliary metal layer M0. When the shielding part 90 is introduced between the first type of connecting line 50 and the second type of connecting line 60, the shielding part 90 can be arranged on the side of the organic layer 70 away from the light-emitting surface of the display panel, or on the side of the organic layer 70 facing the light-emitting surface of the display panel according to actual needs. For example, the shielding part 90 is located in the second metal layer M2 and / or the third metal layer M3. Figure 15 The embodiment shown shows a scheme in which the shielding portion 90 is located in the second metal layer M2. When the shielding portion 90 is located in the second metal layer M2, the corresponding line segment of the second type connecting line 60 that overlaps with the first type connecting line 50 may be located in the third metal layer M3 or the fourth metal layer M4. When the shielding portion 90 is located in the third metal layer M3, for example, please refer to Figure 17 At this time, the line segment of the second type connection line 60 that overlaps with the first type connection line 50 may be located in the fourth metal layer M4, which is not specifically limited in the present disclosure, wherein, Figure 17 Shown Figure 4Another cross-sectional view in the AA direction. In the present disclosure, the shielding portion 90 is disposed in an existing film layer in the display panel, and there is no need to separately introduce a new film layer structure for the shielding portion 90, which is beneficial to simplifying the overall structure of the display panel.

[0070] Please refer to Figure 16 , when the main body portion 61 of the second type of connection line 60 that overlaps with the first type of connection line 50 is located on the side of the organic layer 70 facing the light-emitting surface of the display panel, in an alternative embodiment of the present disclosure, the second type of connection line 60 further includes a lead-out portion 63 connected to the main body portion 61. In the same second type of connection line 60, the lead-out portion 63 is located on the side of the main body portion 61 close to the edge of the display panel, and the lead-out portion 63 is located in the first metal layer M1 and / or the capacitive metal layer MC. When the lead-out portion 63 is introduced into the second type of connection line 60, the lead-out portion 63 is located on the side of the organic layer 70 facing away from the light-emitting surface of the display panel. Through the lead-out portion 63, the electrical connection between the main body portion 61 in the second type of connection line 60 and the connection pad P0 can be achieved. Considering that the connection pad P0 in the display panel is disposed on the side of the organic layer 70 facing away from the light-emitting surface of the display panel, when the lead-out portion 63 is introduced into the second type of connection line 60, the lead-out portion 63 can serve as an intermediate medium to electrically connect the connection pad P0 to the line segment of the second type of connection line 60 located on the side of the organic layer 70 facing the light-emitting surface of the display panel. At the same time, when the lead-out portion 63 is disposed in the first metal layer M1 and / or the capacitive metal layer MC, it is beneficial to simplify the connection difficulty between the lead-out portion 63 and the connection pad P0.

[0071] Figure 16 The illustrated embodiment is described by taking the lead-out portion 63 and the connection pad P0 both being located in the first metal layer M1 as an example, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the lead-out portion 63 and the connection pad P0 may also both be located in the capacitive metal layer MC, or the lead-out portion 63 corresponding to at least one second connection lead is located in the first metal layer M1, the lead-out portion 63 corresponding to at least one second connection lead is located in the capacitive metal layer MC, and the connection pad P0 may be located in the first metal layer M1 or the capacitive metal layer MC.

[0072] Figure 18 Shown is another planar structure diagram of the display panel provided by the embodiment of the present disclosure. Please refer to Figure 18 , in an alternative embodiment of the present disclosure, the wiring area A2 further includes a power supply signal line S1, and the power supply signal line S1 is reused as the shielding portion 90. The power supply signal line S1 is, for example, a positive power supply voltage signal line that provides a positive power supply signal to the pixel driving circuit 20, or a negative power supply voltage signal line that provides a negative power supply signal to the pixel driving circuit 20. The signal transmitted on the power supply signal line S1 is a constant power supply signal. At this time, the power supply signal line S1 located in the wiring area A2 can be reused as the shielding portion 90. Please refer to Figure 17The line segment of the second type of connecting line 60 that overlaps with the first type of connecting line 50 is located on the side of the power signal line S1 facing the light emitting surface of the display panel, and the first type of connecting line 50 is located on the side of the power signal line S1 away from the light emitting surface of the display panel. In the direction perpendicular to the light emitting surface of the display panel, the shielding part 90 isolates the overlapping area of ​​the second type of connecting line 60 and the first type of connecting line 50, and the power signal line S1 is a planar structure as a whole, so that a better signal shielding effect can be formed, avoiding the first type of connecting line 50 and the second type of connecting line 60 from generating coupling capacitance due to overlapping, so it is beneficial to eliminate the influence of the coupling capacitance on the display effect, such as generating unnecessary display stripes, and thus it is beneficial to improve the overall display effect of the display panel.

[0073] In the present embodiment, the power signal line S1 of the wiring area A2 is reused as the shielding part 90 between the first type of connecting line 50 and the second type of connecting line 60. There is no need to introduce a new structure as the shielding part 90 in the display panel. The existing power signal line S1 can be reused. Therefore, while reducing or eliminating the influence of the coupling capacitance between the first type of connecting line 50 and the second type of connecting line 60, it is also helpful to simplify the overall structure of the display panel.

[0074] Figure 19 Shown Figure 1 Another partially enlarged schematic diagram of the wiring area A2 of the display panel and a portion of the first area A1 adjacent to the wiring area A2, Figure 20 Shown Figure 19 For an EE' cross-section diagram of Figure 19 and Figure 20, in an alternative embodiment of the present disclosure, the wiring area A2 further includes a power signal line S1. At least a part of the second type of connection line 60 is provided on the same layer as the power signal line S1 and is insulated from each other. Considering that the power signal line S1 needs to supply power signals to each pixel driving circuit 20 in the first area A1, in order to reduce the voltage drop of the power signal and reduce the difference in the power signals that the pixel driving circuits 20 in different areas can receive, the power signal line S1 in the wiring area A2 is usually set as a planar structure. Optionally, the wiring area A2 can also distribute the power signal line S1 on at least two metal layers. The parallel design of the two metal layers is beneficial to further reducing the impedance on the power signal line S1 and reducing the voltage drop. When the second type of connection line 60 is introduced into the wiring area A2 and at least a part of the line segment of the second type of connection line 60 is provided on the side of the organic layer 70 facing the light-emitting surface of the display panel, this embodiment shows a scheme in which at least a part of the second type of connection line 60 in the wiring area A2 is provided on the same layer as the power signal line S1 and is insulated. At this time, the second type of connection line 60 disconnects the original planar power signal line S1. However, considering that the power signal line S1 is distributed on at least two metal layers, the power signal line S1 provided on the same layer as the second type of connection line 60 can be electrically connected to the planar power signal line S1 on other metal film layers. Therefore, even if it is disconnected by the second type of connection line 60, it will not affect the transmission of the power signal on the power signal line S1. When a part of the line segment of the second type of connection line 60 in this embodiment is provided on the side of the organic layer 70 facing the light-emitting surface of the display panel, the method of providing this part of the second type of connection line 60 on the same layer as the power signal line S1 does not require introducing a separate film layer structure for the second type of connection line 60, which is beneficial to reasonably utilizing the existing film layers of the display panel and simplifying the overall film layer structure of the display panel.

[0075] The specific film layers of the second type of connection line 60 and the power signal line S1 in the display panel will be described below. Please refer to Figure 2 , Figure 19 and Figure 20 , in an alternative embodiment of the present disclosure, the display panel includes a first metal layer M1, a capacitive metal layer MC, and a second metal layer M2 located on the side of the organic layer 70 away from the light-emitting surface, and a third metal layer M3 and a fourth metal layer M4 located on the side of the organic layer 70 facing the light-emitting surface. Among them, the capacitive metal layer MC is located between the first metal layer M1 and the second metal layer M2, and the second metal layer M2 is located on the side of the capacitive metal layer MC facing the organic layer 70. The fourth metal layer M4 is located on the side of the third metal layer M3 away from the organic layer 70; the second type of connection line 60 includes a main body portion 61. Along the direction perpendicular to the plane of the light-emitting surface of the display panel, the main body portion 61 overlaps with the first type of connection line 50; the power signal line S1 is at least distributed on the third metal layer M3 and the fourth metal layer M4, and the main body portion 61 is located on the third metal layer M3 or the fourth metal layer M4.

[0076] This embodiment shows a solution in which the power supply signal line S1 is distributed on the third metal layer M3 and the fourth metal layer M4. The power supply signal lines S1 distributed on the third metal layer M3 and the fourth metal layer M4 are connected in parallel through vias to reduce the overall impedance of the power supply signal line S1 and reduce the signal voltage drop on the power supply signal line S1. In this embodiment, the main body 61 of the second type of connection line 60 that overlaps with the first type of connection line 50 is arranged on the side of the organic layer 70 facing the light-emitting surface of the display panel. Specifically, taking the main body 61 being arranged on the fourth metal layer M4 as an example for illustration, in this way, the distance between the first type of connection line 50 and the main body 61 in the second type of connection line 60 in the overlapping area can be increased, thereby effectively reducing the coupling capacitance between the first type of connection line 50 and the second type of connection line 60, which is beneficial to reducing or eliminating the influence of the coupling capacitance on the display effect. When the main body 61 of the second type of connection line 60 is arranged on the same layer as the power supply signal line S1 located on the fourth metal layer M4, the power supply signal line S1 located on the third metal layer M3 can be reused as the shielding part 90. Along the direction perpendicular to the plane of the light-emitting surface of the display panel, the shielding part 90 is located between the main body 61 of the second type of connection line 60 and the first type of connection line 50, which can effectively shield the signal coupling between the first type of signal line and the second type of signal line and prevent the formation of a coupling capacitance between the two, which may affect the display effect.

[0077] It should be noted that this embodiment only takes the solution in which the main body 61 of the second type of connection line 60 is arranged on the same layer as the power supply signal line S1 located on the fourth metal layer M4 as an example, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the main body 61 in the second type of connection line 60 may also be arranged on the same layer as the power supply signal line S1 located on the third metal layer M3. At this time, the main body 61 of the second type of connection line 60 and the first type of connection line 50 are isolated by the organic layer 70, and the signal coupling between the first type of connection line 50 and the second type of connection line 60 can also be reduced.

[0078] Figure 21 As shown in Figure 19 a cross-sectional view in the FF’ direction. Please continue to refer to Figure 19 and Figure 21 In an alternative embodiment of the present disclosure, the second type of connection line 60 further includes a lead-out portion 63 connected to the main body 61. In the same second type of connection line 60, the lead-out portion 63 is located on the side of the main body 61 close to the edge of the display panel, and the lead-out portion 63 is located on the first metal layer M1 or the capacitor metal layer MC.

[0079] When the main body 61 of the second type of connection line 60 overlaps with the first type of connection line 50, to reduce the coupling capacitance between the second type of connection line 60 and the first type of connection line 50, the present disclosure arranges the main body 61 in the second type of connection line 60 on the side of the organic layer 70 facing the light-emitting surface of the display panel. To achieve the electrical connection between the main body 61 of the second type of connection line 60 and the connection pad P0, in the embodiments of the present disclosure, a lead-out portion 63 arranged on the side of the organic layer 70 facing away from the light-emitting surface of the display panel is introduced, and the lead-out portion 63 is electrically connected to the main body 61 through a via hole. Considering that the connection pad P0 is located on the side of the organic layer 70 facing away from the light-emitting surface of the display panel, when the lead-out portion 63 is arranged in the first metal layer M1 or the capacitor metal layer MC in this embodiment, it is convenient for the electrical connection between the lead-out portion 63 and the connection pad P0. This embodiment is described by taking the main body 61 in the second type of connection line 60 being located in the fourth metal layer M4 and the lead-out portion 63 being located in the capacitor metal layer MC as an example. At this time, the power signal line S1 located in the third metal layer M3 can be reused as a shielding portion 90 to shield the signal between the main body 61 and the first type of connection line 50. However, the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the main body 61 of the second type of connection line 60 can also be arranged in the third metal layer M3, and the lead-out portion 63 can be arranged in the first metal layer M1.

[0080] Please refer to Figure 1 and Figure 19 In an alternative embodiment of the present disclosure, the wiring area A2 includes a connection pad P0, and the connection pad P0 is located on the side of the first type of connection line 50 and the second type of connection line 60 close to the edge B of the display panel; the connection pad P0 includes a first connection pad P1 and a second connection pad P2, the first connection pad P1 is electrically connected to the first type of connection line 50, and the second connection pad P2 is electrically connected to the second type of connection line 60; the wiring area A2 includes a first pad area Q1 and a second pad area Q2 located on at least one side of the first pad area Q1 along the first direction D1, the first connection pad P1 is located in the first pad area Q1, the second connection pad P2 is located in the second pad area Q2, and the first direction D1 is parallel to the extension direction of the edge B of the display panel.

[0081] The second type of connection line 60 in the disclosed embodiment is electrically connected to the first signal line 40 for providing a control signal to the gate drive circuit 10, and the first type of connection line 50 is electrically connected to the data line 30 for providing a data signal to the data line 30. Compared with the data line 30 in the display panel, the number of the first signal line 40 is small, and the number of the corresponding second type of connection line 60 and the second connection pad P2 is small, and the number of the first type of connection line 50 corresponding to the first connection pad P1 is large. In this embodiment, the first connection pads P1 are uniformly arranged in the first pad area Q1, and the second connection pads P2 with a small number are arranged in the second pad area Q2, and the second pad area Q2 is located at least on one side of the first pad area Q1 along the first direction D1, so that the second connection pads P2 will not affect the original arrangement and connection of the first connection pads P1, which is more conducive to the matching of the connection pads P0 of the wiring area A2 with the pads on the control chip, and there is no need to adjust the structure of the pads on the control chip, which is conducive to reducing costs.

[0082] It should be noted that Figure 1 and Figure 19 Only the solution of setting a second pad area Q2 on one side of the first pad area Q1 along the first direction D1 when the display panel includes a group of gate driving circuits 10 is shown. When the display panel includes two or more groups of gate driving circuits 10, a second pad area Q2 can also be set on both sides of the first pad area Q1 along the first direction D1. The present disclosure does not make specific limitations on this.

[0083] Please continue to refer to Figure 19 and Figure 21 In an optional embodiment of the present disclosure, the second type of connecting line 60 includes a main body 61 and a lead-out portion 63 connected to the main body 61, the main body 61 is located on the side of the organic layer 70 facing the light-emitting surface, and the lead-out portion 63 is located on the side of the organic layer 70 away from the light-emitting surface; the main body 61 is electrically connected to the second connecting pad P2 through the lead-out portion 63.

[0084] In the present disclosure, in order to reduce the coupling capacitance caused by the overlap of the first type of connection line 50 and the second type of connection line 60, the main body portion 61 of the second type of connection line 60 that overlaps with the first type of connection line 50 is disposed on the side of the organic layer 70 facing the light-emitting surface of the display panel, and the first type of connection line 50 is disposed on the side of the organic layer 70 away from the light-emitting surface of the display panel, so as to reduce the coupling capacitance by increasing the distance therebetween. When the main body portion 61 of the second type of connection line 60 is disposed on the side of the organic layer 70 facing the light-emitting surface of the display panel, when the lead-out portion 63 is introduced into the second type of connection line 60, the lead-out portion 63 is located on the side of the organic layer 70 away from the light-emitting surface of the display panel, and the electrical connection between the main body portion 61 in the second type of connection line 60 and the connection pad P0 can be realized through the lead-out portion 63. Considering that the connection pad P0 in the display panel is disposed on the side of the organic layer 70 away from the light-emitting surface of the display panel, when the lead-out portion 63 is introduced into the second type of connection line 60, the lead-out portion 63 can be used as an intermediate medium to electrically connect the connection pad P0 and the line segment of the second type of connection line 60 located on the side of the organic layer 70 facing the light-emitting surface of the display panel.

[0085] Please continue to refer to Figure 1 and Figure 19 In an alternative embodiment of the present disclosure, the gate driving circuit 10 includes a first group of gate driving circuits 101. Along the second direction D2, the first group of gate driving circuits 101 does not overlap with both the first pad region Q1 and the second pad region Q2, and the second direction D2 intersects with the first direction D1.

[0086] This embodiment shows that when the first group of gate driving circuits 101 is introduced into the first region A1 of the display panel, the first group of gate driving circuits 101 is disposed at a position in the first region A1 close to the edge extending along the second direction D2 of the display panel. Considering that in order to facilitate the connection between the wiring in the first region A1 and the connection pad P0, the first pad region Q1 and the second pad region Q2 are generally disposed at the middle position below the first region A1. Therefore, along the second direction D2, the first group of gate driving circuits 101 does not overlap with both the first pad region Q1 and the second pad region Q2. In the present disclosure, the second pad region Q2 is disposed on at least one side of the first pad region Q1 along the first direction D1, so that the first group of gate driving circuits 101 and the second pad region Q2 are located on the same side of the first pad region Q1 along the first direction D1. In this way, when the second type of connection line 60 corresponding to the first signal line 40 is electrically connected to the second connection pad P2 in the second pad region Q2, the second type of connection line 60 can be connected to the second connection pad P2 in the vicinity, so as to reduce the number of the first type of connection lines 50 overlapping with the second type of connection line 60, which is beneficial to reducing the coupling capacitance between the second type of connection line 60 and the first type of connection line 50, and thus beneficial to improving the display effect of the display panel.

[0087] It should be noted thatFigure 19 The embodiment only shows a solution in which the display panel includes a first set of gate driving circuits 101 and the first set of gate driving circuits 101 are arranged at a position in the first area A1 close to the edge of the display panel extending along the second direction D2. In some other embodiments of the present disclosure, the display panel may further include two first sets of gate driving circuits 101, and the two first sets of gate driving circuits 101 may be respectively arranged at positions close to the two edges of the display panel extending along the second direction D2. Correspondingly, two second pad areas Q2 may be arranged, and the two second pad areas Q2 are located on both sides of the first pad area Q1 along the first direction D1. The present disclosure does not specifically limit this.

[0088] The above embodiment shows a solution in which when introducing the gate driving circuit 10 into the first area A1, the gate driving circuit 10 is arranged at a position close to the edge of the display panel extending along the second direction D2. In some other embodiments of the present disclosure, the gate driving circuit 10 may also be arranged at a position in the first area A1 close to the center of the first area A1. For example, please refer to Figure 22 , Figure 22 shown is another planar structure diagram of the display panel provided by the embodiment of the present disclosure. In an alternative embodiment of the present disclosure, the gate driving circuit 10 includes a first set of gate driving circuits 102. Along the second direction D2, the first set of gate driving circuits 102 overlap with the first pad area Q1, and the second direction D2 intersects with the first direction D1. When the first set of gate driving circuits 102 are arranged at a position in the first area A1 close to the central area, the gate driving circuit 10 can transmit the scanning signal from the middle area of the scanning line L1 to both sides of the scanning line L1, thereby facilitating the improvement of the transmission efficiency of the scanning signal. It should be noted that, Figure 22 The embodiment only shows a solution in which one first set of gate driving circuits 102 are arranged at a position close to the central area of the first area A1. In some other embodiments of the present disclosure, two or more first sets of gate driving circuits 102 may also be arranged at a position close to the central area of the first area A1. The present disclosure does not specifically limit this. It should also be noted that when the first set of gate driving circuits 102 are arranged at a position in the first area A1 close to the central area, the shift registers in the first set of gate driving circuits 102 may adopt an arrangement manner as shown in Figure 22 shown, located between two adjacent columns of pixel driving circuits 20, but the present disclosure is not limited thereto. In some other embodiments of the present disclosure, the shift registers may also be located between two adjacent rows of pixel driving circuits 20.

[0089] Figure 23 shown is Figure 22 a partial enlarged schematic diagram of the wiring area A2 of the display panel in Figure 24The figure shows a connection diagram of the second type of connecting wire, auxiliary lead and second connecting pad. Please refer to Figure 23 and Figure 24 In an optional embodiment of the present disclosure, in the wiring area A2, the second type of connecting line 60 extends along the second direction D2, and the second direction D2 intersects with the first direction D1; the wiring area A2 also includes an auxiliary lead L0, one end of the auxiliary lead L0 is electrically connected to the second connecting pad P2, and the other end is electrically connected to the end of the second type of connecting line 60 away from the first area A1.

[0090] In this embodiment, in order to avoid changing the control chip structure, the second pad area Q2 where the second connection pad P2 is located is still arranged on at least one side of the first pad area Q1 along the first direction D1 in the embodiment of the present disclosure. When the first group of gate drive circuits 101 is arranged in the first area A1 near the central area, since the second type of connection line 60 connected to the first signal line 40 is far away from the second connection pad P2, if the electrical connection with the second connection pad P2 is achieved by pulling an oblique line, the second type of connection line 60 will overlap with more first type of connection lines 50, and form coupling capacitors with different first type of connection lines 50, which is not conducive to improving the display effect. Therefore, in this embodiment, the second type of connection line 60 is extended along the second direction D2, which can reduce the number of first type of connection lines 50 overlapped with the second type of connection line 60, thereby helping to reduce the signal coupling between the second type of connection line 60 and the first type of connection line 50, and helping to improve the display effect. When the second-type connecting line 60 extends along the second direction D2, an auxiliary lead L0 is further introduced in this embodiment, and the auxiliary lead L0 is used to respectively connect the second-type connecting line 60 and the corresponding second connecting pad P2, thereby realizing the electrical connection between the second-type connecting line 60 and the second connecting pad P2, and further realizing the electrical connection between the first signal line 40 and the second connecting pad P2.

[0091] Please continue to refer to Figure 23 and Figure 24 In an optional embodiment of the present disclosure, the auxiliary lead L0 does not overlap with the first type connection line 50 in a direction perpendicular to the plane where the light emitting surface of the display panel is located. When the auxiliary lead L0 is introduced to connect the second type connection line 60 and the corresponding second connection pad P2, the auxiliary lead L0 is prevented from overlapping with the first type connection line 50 in this embodiment, which is conducive to preventing the signal on the auxiliary lead L0 from coupling with the signal on the first type connection line 50 and affecting the display effect.

[0092] Please continue to refer to Figure 23 and Figure 24 In an optional embodiment of the present disclosure, along a direction perpendicular to the plane where the light emitting surface of the display panel is located, the auxiliary lead is located on the side of the connecting pad P0 away from the light emitting surface. Figure 2, when introducing auxiliary leads in the display panel, the auxiliary leads can be arranged in the film layer under the connection pad P0. When the connection pad P0 is located in the capacitor metal layer MC, the auxiliary leads can be arranged in the first metal layer M1 or the auxiliary metal layer M0. When the connection pad P0 is located in the first metal layer M1, it can be seen that the auxiliary leads are arranged in the auxiliary metal layer M0. In this way, the method of routing the auxiliary leads on the side of the connection pad P0 facing away from the light-emitting surface of the display panel can reduce the space occupied by the auxiliary leads and the connection pad P0 on the display panel along the second direction D2, which is beneficial to realizing the narrow bezel or extremely narrow bezel design of the display panel.

[0093] It should be noted that when setting the connection pad P0 in the wiring area A2 in the embodiments of the present disclosure, the connection pad P0 can be used to bind to the control chip IC or the flexible printed circuit board FPC, or can be extended to the side of the backlight surface of the display panel through side routing and then bind to the control chip IC. Figure 25 and Figure 26 respectively show another planar structure diagram of the display panel provided by the embodiments of the present disclosure. Figure 25 and Figure 26 The shown embodiment shows a scheme of binding the connection pad P0 to the control chip IC. Figure 25 The shown embodiment shows a scheme of binding the connection pad P0 to the control chip IC after the second type of connection line 60 is connected to the connection pad P0. Figure 26 The embodiment shows a scheme that the second type of connection line 60 is first electrically connected to the flexible printed circuit board FPC, and then the connection pad P0 is electrically connected through the routing led out by the flexible printed circuit board FPC, all within the scope claimed by the present disclosure.

[0094] Based on the same inventive concept, the present disclosure also provides a display device. Figure 27 Shown is a schematic structural diagram of the display device provided by the embodiments of the present disclosure. Please refer to Figure 27 , the display device 200 includes the display panel 100 in any of the above embodiments. The display device 200 provided by the embodiments of the present disclosure can be any electronic device with a display function, such as a tablet computer with a display function, a display product in a display cabinet, a television, or a vehicle-mounted display device. The display device 200 provided by the embodiments of the present disclosure has the beneficial effects of the display panel 100 provided by the embodiments of the present disclosure. For specific descriptions of the display panel 100, reference can be made to the above embodiments, and details will not be repeated herein.

[0095] It can be understood that Figure 27 only a rectangular structure is used to illustrate the display device. In some other embodiments of the present disclosure, the display device 200 can also be embodied as a circular, oval or any other feasible shape, and the present disclosure does not specifically limit this.

[0096] In summary, the display panel and the display device provided by the embodiments of the present disclosure at least have the following technical effects:

[0097] In the display panel and the display device provided by the embodiments of the present disclosure, in the overlapping area of the first type of connection line and the second type of connection line, there is at least an organic layer between the first type of connection line and the second type of connection line. This organic layer is, for example, a film layer in the display panel that plays a planarization role and has a relatively large thickness. When the first type of connection line and the second type of connection line are at least isolated by the organic layer in the overlapping area, it is equivalent to increasing the distance between the first type of connection line and the second type of connection line in the overlapping area. When the first type of connection line and the second type of connection line in the overlapping area are respectively used as the two electrodes of a capacitor, the greater the distance between the two electrodes, the smaller the coupling capacitance between them. Therefore, it is beneficial to reduce the coupling capacitance generated when the first type of connection line and the second type of connection line overlap, and it is beneficial to weaken or eliminate the phenomenon of abnormal display stripes caused by this coupling capacitance. Therefore, it is beneficial to improve the overall display effect.
