Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] From the CRT (Cathode Ray Tube) era to the LCD (Liquid Crystal Display) era, and now to the OLED (Organic Light-Emitting Diode) display era and the LED display era, the display industry has experienced decades of development and has changed with each passing day. The display industry is closely related to our lives, from traditional mobile phones, tablets, TVs, computers to today's smart wearable devices, virtual reality devices, car displays and other electronic devices, all of which are inseparable from display technology.

[0003] A large number of signal lines and electronic components are arranged in the display panel, and static electricity in the display panel can easily affect the display effect. Therefore, how to reduce the impact of static electricity on the display panel has become one of the technical problems that need to be solved urgently at this stage. Summary of the invention

[0004] In view of this, the present invention provides a display panel and a display device, aiming to reduce or avoid the influence of static electricity on the display effect.

[0005] In a first aspect, the present invention provides a display panel, which is provided with a display area and a non-display area surrounding the display area, and the display panel includes:

[0006] substrate;

[0007] A plurality of scan lines and a plurality of data lines are arranged on the substrate, the data lines are located in the display area, the data lines extend along a first direction and are arranged along a second direction, the scan lines extend along the second direction and are arranged along the first direction, and the first direction and the second direction intersect;

[0008] At least one dummy signal line is located in the non-display area, the dummy signal line is parallel to the data line, and the dummy signal line includes a first dummy signal line adjacent to an outer edge of the non-display area;

[0009] Along the second direction, an end portion of at least one scan line is located between the first dummy signal line and the data line.

[0010] In a second aspect, based on the same inventive concept, the present invention further provides a display device, comprising the display panel provided in the first aspect of the present invention.

[0011] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0012] The display panel and the display device provided by the embodiment of the present invention include cross-arranged scan lines and data lines, wherein the data lines extend along a first direction, the scan lines extend along a second direction, the data lines are located in the display area, and are used to provide data signals for sub-pixels, and the scan lines are used to provide scan signals for sub-pixels. A dummy signal line is arranged in the non-display area, and the dummy signal line is parallel to the data line, wherein the dummy signal line farthest from the data line is the first dummy signal line. Since the extension direction of the scan line overlaps with the data line, the end of the scan line is very likely to extend to the non-display area. When a metal signal line is arranged in the non-display area, a tip discharge phenomenon is very likely to occur at the end of the scan line. If the end overlaps with the first dummy signal line in the thickness direction of the display panel, the static electrode is likely to break through the insulating layer between the end of the scan line and the first dummy signal line, resulting in the scan line being electrically connected to the first dummy signal line, thereby affecting the normal display of the sub-pixel connected to the scan line. Therefore, the present invention arranges the end of the scanning line between the first dummy signal line and the data line to avoid overlapping of the end of the scanning line and the first dummy signal line in the thickness direction of the display panel. This can not only increase the distance between the end of the scanning line and the edge of the non-display area along the second direction and reduce the possibility of tip discharge, but also avoid the phenomenon that the end of the scanning line is electrically connected to the first dummy signal line which may be caused by tip discharge, thereby avoiding the problem of display abnormality caused by the electrical connection between the scanning line and the first dummy signal line, so it is beneficial to avoid the influence of static electricity on the display effect.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

[0014] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0044] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] It is obvious to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present invention can be combined with each other without contradiction.

[0048] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0049] Figure 1 FIG. 1 is a diagram showing a relative position relationship among a scan line 10 ′, a dummy signal line 30 ′ and a data line 20 ′ in a display panel in the related art. Figure 2 Shown Figure 1 A BB-direction cross-sectional view of the signal line in the display panel. In the related art, a dummy signal line 30' and a metal line 40' are provided in the non-display area NA of the display panel, and the scan line 10' extends into the non-display area NA. The scan line 10' and the dummy signal line 30' overlap in the thickness direction. It is very likely that tip discharge will occur between the end of the scan line 10' and the metal line 40'. The static charge caused by the tip discharge may break through the insulating layer 90' between the scan line 10' and the dummy signal line 30', causing the scan line 10' to be electrically connected to the dummy signal line 30'. In this way, the signal on the scan line 10' becomes abnormal, causing the sub-pixel connected to the scan line 10' to display abnormally, and the display panel as a whole displays abnormally. For example, when displaying a white screen, the sub-pixel connected to the scan line will appear black, and dark lines will appear on the display panel.

[0050] To this end, the present invention provides a display panel, which is provided with a display area and a non-display area surrounding the display area, and the display panel includes: a substrate; a plurality of scan lines and a plurality of data lines arranged on the substrate, the data lines are located in the display area, the data lines extend along a first direction and are arranged along a second direction, the scan lines extend along a second direction and are arranged along the first direction, and the first direction and the second direction intersect; at least one dummy signal line is located in the non-display area, the dummy signal line is parallel to the data line, and the dummy signal line includes a first dummy signal line adjacent to the outer edge of the non-display area; along the second direction, one end of at least one scan line is located between the first dummy signal line and the data line. By setting the end of the scan line away from the first dummy signal line, the two are prevented from overlapping in the thickness direction, which is conducive to avoiding the problem of abnormal display caused by electrostatic breakdown resulting in the end of the scan line connecting with the first dummy signal line, and is conducive to improving the overall display effect.

[0051] The above is the core idea of ​​the present invention. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the embodiment of the present invention.

[0052] Figure 3 FIG. 1 is a top view of a display panel provided by an embodiment of the present invention. Figure 4 Shown Figure 3 An enlarged schematic diagram of the area Q of the display panel, Figure 5 Shown Figure 4 For a CC cross-sectional view of Figures 3 to 5 An embodiment of the present invention provides a display panel, which is provided with a display area AA and a non-display area NA surrounding the display area AA. The display panel 100 includes:

[0053] Substrate 00;

[0054] A plurality of scan lines 10 and a plurality of data lines 20 are disposed on a substrate 00, wherein the data lines 20 are located in a display area AA, the data lines 20 extend along a first direction D1 and are arranged along a second direction D2, the scan lines 10 extend along the second direction D2 and are arranged along the first direction D1, and the first direction D1 and the second direction D2 intersect;

[0055] At least one dummy signal line 30 is located in the non-display area NA, the dummy signal line 30 is parallel to the data line 20, and the dummy signal line 30 includes a first dummy signal line 31 adjacent to an outer edge of the non-display area NA;

[0056] Along the second direction D2 , one end of at least one scan line 10 is located between the first dummy signal line 31 and the data line 20 .

[0057] It should be noted that Figure 3 The rectangular display panel is used as an example for illustration, and the shape of the display panel is not limited. In some other embodiments of the present invention, the shape of the display panel can also be embodied as other shapes, such as a rounded rectangle, a circle, or other feasible shapes. Optionally, in the display panel provided in the embodiment of the present invention, the scan line 10 extends along the second direction D2, and the data line 20 extends along the first direction D1. It should also be noted that Figure 3 The scan line 10 and the data line 20 are described by taking a straight line structure as an example, and the actual line shapes of the scan line 10 and the data line 20 are not limited. As long as the overall extension direction of the scan line 10 is the second direction D2 and the overall extension direction of the data line 20 is the first direction D1, on this basis, the scan line 10 and the data line 20 may not be a strictly straight line structure. Figure 3 Only part of the scan lines 10 and the data lines 20 in the display panel are illustrated, which does not represent the actual number of the scan lines 10 and the data lines 20 actually included in the display panel. Figure 5 The film layer structure shown is only used to reflect the relative position relationship between the first dummy signal line 31 and the scanning line 10 , and does not limit the actual film layer structure and the number of film layers of the display panel.

[0058] Specifically, the display panel provided in the embodiment of the present invention includes a scan line 10 and a data line 20 arranged crosswise, wherein the data line 20 extends along a first direction D1, and the scan line 10 extends along a second direction D2, the data line 20 is located in the display area AA, and is used to provide a data signal for a sub-pixel in the display panel, and the scan line 10 is used to provide a scan signal for the sub-pixel. A dummy signal line 30 is arranged in the non-display area NA, and the dummy signal line 30 is parallel to the data line 20, wherein the dummy signal line 30 farthest from the data line 20 is the first dummy signal line 31, and if a plurality of dummy signal lines 30 are arranged in the non-display area NA on the same side of the display area AA, the first dummy signal line 31 can be regarded as a dummy signal line 30 farthest from the outer edge of the display area AA.

[0059] Since the extension direction of the scan line 10 intersects with the data line 20, the end of the scan line 10 may extend to the non-display area NA. When the non-display area NA is provided with a signal line 40 (for example, a metal trace with a larger area, such as a block metal structure, whose line width is much larger than the line width of the scan line 10), a tip discharge phenomenon is very likely to occur between the end of the scan line 10 and the signal line 40. If the end of the scan line 10 overlaps with the first dummy signal line 31 in the thickness direction of the display panel, the static electrode may break through the insulating layer J between the end of the scan line 10 and the first dummy signal line 31, causing the scan line 10 to be electrically connected to the first dummy signal line 31, thereby affecting the normal display of the sub-pixel connected to the scan line 10, such as the appearance of a dark line. Therefore, along the second direction D2, the embodiment of the present invention sets the end of the scan line 10 between the first dummy signal line 31 and the data line 20 to avoid the overlap of the end of the scan line 10 and the first dummy signal line 31 in the thickness direction of the display panel. On the one hand, the distance between the end of the scan line 10 and the edge of the non-display area NA along the second direction D2 is increased, which is beneficial to increase the distance between the end of the scan line 10 and the signal line 40 in the non-display area NA, and reduce the possibility of tip discharge between the end of the scan line 10 and the signal line 40; on the other hand, the end of the scan line 10 and the first dummy signal line 31 do not overlap in the thickness direction of the display panel, which is also beneficial to avoid the phenomenon of electrical connection between the end of the scan line 10 and the first dummy signal line 31 which may be caused by tip discharge, thereby avoiding the display abnormality caused by the electrical connection between the scan line 10 and the first dummy signal line 31, so it is beneficial to avoid the influence of static electricity on the display effect and to improve the overall display effect of the display panel.

[0060] Continue to refer Figure 3 and Figure 4 In an optional embodiment of the present invention, the scan line 10 includes a first end D01 and a second end D02 opposite to each other along the second direction D2, the first end D01 is located between the first dummy signal line 31 and the data line 20, and the distance between the first end D01 and the first dummy signal line 31 is D, D ≥ 30 μm. Optionally, the distance between the first end D01 and the first dummy signal line 31 can be regarded as the width of the interval between the first end D01 and the first dummy signal line 31 along the second direction D2.

[0061] Specifically, when the sub-pixels of the display panel are displayed, the scan line 10 is used to provide a scan signal to the corresponding sub-pixel. Of the first end D01 and the second end D02 of the scan line 10 that are relatively arranged, the second end D02 can be regarded as an end electrically connected to other devices or circuits to obtain a scan signal; the first end D01 can be regarded as an end that is not directly connected to other devices or circuits, and the scan signal is transmitted to the first end D01 through the second end D02. When the non-display area NA is provided with a signal line 40, the signal line 40 is usually arranged on the side of the first dummy signal line 31 away from the display area AA. Along the second direction D2, the embodiment of the present invention arranges the first end D01 of the scan line 10 on the side of the first dummy signal line 31 facing the data line 20. On this basis, when the distance between the first end D01 of the scan line 10 and the first dummy signal line 31 is small, for example, less than 30 μm, the distance between the first end D01 and the signal line 40 will also be small, and tip discharge may still occur between the first end D01 and the signal line 40. When the embodiment of the present invention sets the distance between the first end D01 and the first dummy signal line 31 to D≥30μm, the distance between the first end D01 and the first dummy signal line 31 is increased, which is equivalent to further increasing the distance between the first end D01 and the signal line 40. The greater the distance between the first end D01 and the signal line 40, the smaller the possibility of tip discharge between the first end D01 and the signal line 40 will be, which is more conducive to avoiding static electricity generated by tip discharge that causes the scanning line 10 to be electrically connected to the dummy signal line 30, and thus is beneficial to ensuring the display effect of the display panel.

[0062] It should be noted that, in the embodiment shown in the present invention, the display area AA may be a region that does not include dummy signal lines and dummy pixels.

[0063] It should be noted that the above embodiment only shows a solution in which one dummy signal line 30 is provided in the non-display area NA on the same side of the display area AA. In some other embodiments of the present invention, two or more dummy signal lines 30 may be provided in the non-display area on the same side of the display area AA. For example, please refer to Figure 6 ,in, Figure 6 Shown Figure 3An enlarged schematic diagram of the area Q of the display panel in FIG. 1 , assuming that the dummy signal line 30 between the first dummy signal line 31 and the data line 20 is the second dummy signal line 32, along the thickness direction of the display panel, the scanning line 10 may overlap with the second dummy signal line 32, but not with the first dummy signal line 31. At this time, the first end D01 of the scanning line 10 is located between the first dummy signal line 31 and the second dummy signal line 32, and the distance D' between the first end D01 and the second dummy signal line 32 is greater than the width of at least one sub-pixel, so that a certain distance can be ensured between the first end D01 and the second dummy signal line 32, even if the first end D01 of the scanning line 10 has a tip discharge problem, static electricity will not break through the insulating layer between the scanning line 10 and the second dummy signal line 32, which is conducive to ensuring the display effect of the display panel.

[0064] Continue to refer Figure 4 In an optional embodiment of the present invention, the first end portion D01 and the first dummy signal line 31 are located in the non-display area NA on the same side of the display area AA.

[0065] Specifically, when the distance between the first end D01 and the first dummy signal line 31 is increased along the second direction D2, a feasible implementation method is to retract the first end D01 of the scan line 10 toward the display area AA, that is, to reduce the distance between the first end D01 of the scan line 10 and the edge of the display area AA, and the first end D01 is still located in the non-display area NA. When the first end D01 is set in the non-display area NA, the first end D01 will be shielded by the black matrix in the display panel, thereby avoiding the problem of the first end D01 being visible, which is conducive to ensuring the overall display effect of the display panel.

[0066] Figure 7 Shown Figure 3 An enlarged schematic diagram of a portion of the scan line 10 in the non-display area NA and the display area AA of the display panel is shown. This embodiment shows another feasible arrangement scheme of the first end portion D01 of the scan line 10.

[0067] Please refer to Figure 7 In an optional embodiment of the present invention, the first end portion D01 is located in the display area AA.

[0068] When the distance between the first end D01 and the first dummy signal line 31 is increased by retracting the first end D01 toward the display area AA, the present embodiment shows a scheme of retracting the first end D01 of the scan line 10 into the display area AA. When the first end D01 is located in the display area AA, the distance between the first end D01 and the signal line 40 in the non-display area NA is further increased, effectively avoiding the phenomenon of tip discharge between the first end D01 of the scan line 10 and the signal line 40. It should be noted that when the first end D01 is set in the display area AA, the first end D01 can be set as close to the edge of the display area AA as possible to ensure that the scan line 10 can be effectively electrically connected to each sub-pixel corresponding thereto.

[0069] Continue to refer Figure 3 In an optional implementation manner of the present invention, the first end D01 of each scan line 10 is located between the first dummy signal line 31 and the data line 20 .

[0070] Hundreds or thousands of scan lines 10 are usually arranged in the display panel. When electrostatic discharge occurs between the first end D01 of one or some scan lines 10 and the signal line 40, the scan line 10 and the overlapping dummy signal line 30 are very likely to be electrically connected due to electrostatic breakdown, affecting the display effect of the sub-pixel connected to the scan line 10, and further affecting the overall display effect of the display panel. In the embodiment of the present invention, along the second direction D2, the first end of each scan line 10 is arranged between the first dummy signal line 31 and the data line 20, on the one hand, the distance between the first end D01 of the scan line 10 and the signal line 40 in the non-display area NA is increased, and on the other hand, the first dummy signal line 31 and the scan line 10 are prevented from overlapping in the thickness direction of the display panel, so that the phenomenon of tip discharge at the first end D01 of each scan line 10 can be avoided, and the first dummy signal line 31 can be prevented from being electrically connected to the scan line 10, so it is beneficial to ensure the overall display effect of the display panel.

[0071] Figure 8 FIG. 1 is another top view of a display panel provided by an embodiment of the present invention. Please refer to FIG. Figure 8 In an optional embodiment of the present invention, the display panel further includes a conductive metal portion 50 located in the non-display area NA, and the conductive metal portion 50 is at least partially arranged around the display area AA; the width of the conductive metal portion 50 along the second direction D2 is greater than the line width of the scan line 10; in the non-display area NA, the conductive metal portion 50 is located on a side of the first dummy signal line 31 away from the display area AA, and the conductive metal portion 50 receives a fixed potential signal.

[0072] The signal line 40 mentioned in the above embodiment can be embodied as the conductive metal part 50 in this embodiment. The conductive metal part 50 is arranged in the non-display area NA and at least partially surrounds the display area AA, and is used to provide a fixed potential signal to the sub-pixels in the display area AA. The fixed potential signal can be, for example, a common voltage signal. Fig. 9 Shown Figure 8 A DD-direction cross-sectional view of a display panel, the display panel includes a driving layer 01 and a pixel electrode T1 and a common electrode T2 arranged on one side of the driving layer 01. The pixel electrode T1 is electrically connected to the driving layer 01 for receiving a driving signal provided by the driving layer 01; the common electrode T2 is electrically connected to the aforementioned conductive metal portion 50 for receiving a common voltage signal transmitted by the conductive metal portion 50. The electric field formed between the pixel electrode T1 and the common electrode T2 is used to drive the liquid crystal deflection to achieve the display function of the display panel. In an embodiment of the present invention, the line segment of the conductive metal portion 50 along the second direction D2 is set to be larger than the line width of the scanning line 10. When a conductive metal portion 50 with a larger line width is used to provide a common voltage signal to the common electrode T2, the impedance of the conductive metal portion 50 can be effectively reduced, the loss of the common voltage during the transmission process can be reduced, and the uniformity of the signal received by the common electrode T2 in different areas can be improved, thereby facilitating the improvement of the overall display uniformity of the display panel. Optionally, the display panel includes an array substrate and an opposing substrate arranged relatively to each other. Fig. 9 Only a solution is shown in which both the pixel electrode T1 and the common electrode T2 are disposed on the array substrate of the display panel, and the common electrode T2 is disposed between the pixel electrode T1 and the driving layer 01, but the actual position of the common electrode T2 is not limited. In some other embodiments of the present invention, when both the pixel electrode T1 and the common electrode T2 are disposed on the array substrate, the common electrode T2 may also be disposed on a side of the pixel electrode T1 away from the driving layer 01. In some other embodiments of the present invention, the pixel electrode T1 and the common electrode T2 may also be disposed on different substrates, for example, the pixel electrode T1 is disposed on the array substrate, and the common electrode T2 is disposed on the opposite substrate.

[0073] Optionally, the driving layer 01 includes a transistor T, wherein the gate of the transistor T is located in the first metal layer M1, and the source and drain are located in the second metal layer M2. Optionally, the scan line 10 in the display panel is located in the first metal layer M1, and the data line 20 is located in the second metal layer M2.

[0074] Please combine Figures 4 to 9, the line width of the conductive metal portion 50 is relatively large. Compared with the first end D01 of the scan line 10, the conductive metal portion 50 in the non-display area NA can be regarded as the above-mentioned signal line 40, for example, it can be embodied as a block metal structure. If the conductive metal portion 50 and the scan line 10 are located in the same layer, and the first end D01 of the scan line 10 is close to the conductive metal portion 50, the first end D01 and the conductive metal portion 50 may have a tip discharge phenomenon. Therefore, in the embodiment of the present invention, the distance between the first end D01 and the first dummy signal line 31 is increased to increase the distance between the first end D01 and the conductive metal portion 50, thereby avoiding the phenomenon of electrostatic discharge between the first end D01 and the conductive metal portion 50.

[0075] Fig.10 Shown Figure 8 An EE-direction cross-sectional view of the display panel in this embodiment shows a relative position relationship between the first substrate 101 and the second substrate 102 in the display panel. Fig.11 FIG. 1 is a top view of a conductive metal portion 50 provided in an embodiment of the present invention.

[0076] Please refer to Fig.10 and Fig.11 In an optional embodiment of the present invention, the display panel includes a first substrate 101 and a second substrate 102 arranged opposite to each other. Figures 5 to 9 The substrate 00 , the scan line 10 , the data line 20 , the dummy signal line 30 , and the conductive metal portion 50 are all located on the first substrate 101 .

[0077] In the non-display area NA, a frame glue 103 is arranged between the first substrate 101 and the second substrate 102, and the conductive metal part 50 overlaps with the frame glue 103 along the thickness direction of the display panel; the conductive metal part 50 includes a plurality of openings 501, and the openings 501 penetrate the conductive metal part 50 along the thickness direction of the conductive metal part 50; along the thickness direction of the display panel, the frame glue 103 overlaps with the openings 501.

[0078] Optionally, the display panel provided in the embodiment of the present invention is a liquid crystal display panel, and the relatively arranged first substrate 101 and second substrate 102 are bonded together by a frame glue 103 located in the non-display area NA, and the space formed by the first substrate 101, the second substrate 102, and the frame glue 103 is filled with liquid crystal.

[0079] When the first substrate 101 and the second substrate 102 are bonded together by using the sealant 103, the sealant 103 is originally in liquid form during the manufacturing process, and the sealant 103 can be solidified by irradiating the liquid sealant 103 with light. When the light source irradiating the sealant 103 is located on the side of the first substrate 101 away from the second substrate 102, since the conductive metal part 50 is provided in the non-display area NA, the conductive metal part 50 will block the light and affect the solidification of the sealant 103. Therefore, in the embodiment of the present invention, a plurality of openings 501 are formed on the conductive metal part 50, and the openings 501 penetrate the conductive metal part 50 along the thickness direction of the conductive metal part 50. Since the frame glue 103 overlaps with the opening 501 along the thickness direction of the display panel, when light irradiates the frame glue 103 in the non-display area NA from the side of the first substrate 101 away from the second substrate 102, it can be irradiated to the frame glue 103 through the opening 501, thereby achieving reliable curing of the frame glue 103.

[0080] Optionally, when the openings 501 are formed on the conductive metal part 50 , the openings 501 may be evenly arranged on the conductive metal part 50 , for example, the distance between any two adjacent openings 501 is equal, so that light can be evenly projected toward the frame glue 103 , thereby facilitating improving the uniformity of the curing effect of the frame glue 103 .

[0081] It should be noted that the embodiment of the present invention does not limit the shape, size and number of the openings 501 on the conductive metal part 50. Fig.11 In addition to the square opening 501 shown, the opening 501 can also be set to other shapes according to actual needs.

[0082] Continue to refer Figure 5 In an optional embodiment of the present invention, the conductive metal portion 50 and the scanning line 10 are arranged in the same layer.

[0083] In this embodiment, a film layer structure of the conductive metal part 50 and the scanning line 10 is illustrated, wherein the conductive metal part 50 and the scanning line 10 are located in the same metal layer. When the two are located in the same metal layer, there is no need to introduce different film layers for the conductive metal part 50 and the scanning line 10 respectively. The production of the conductive metal part 50 and the scanning line 10 can be completed in the same production process, which is beneficial to simplifying the film layer structure of the display panel, simplifying the production process of the display panel, and improving production efficiency.

[0084] Although there is a high possibility of tip discharge between the first end D01 of the scan line 10 and the conductive metal portion 50 when the conductive metal portion 50 and the scan line 10 are arranged in the same layer, the present invention reduces the probability of tip discharge between the two by increasing the distance between the first end D01 of the scan line 10 and the conductive metal portion 50, and arranges the first scan line G1 and the first dummy signal line 31 not to overlap in the thickness direction of the display panel, thereby avoiding the possibility that the tip discharge may cause electrical connection between the scan line 10 and the first dummy signal line 31.

[0085] Fig.12 FIG. 1 is a diagram showing a film relationship between the conductive metal portion 50, the first dummy signal line 31 and the scan line 10 in the first non-display area NA1. Fig.12 In an optional embodiment of the present invention, along the thickness direction of the display panel, at least one insulating layer is included between the film layer where the conductive metal part 50 is located and the film layer where the scanning line 10 is located.

[0086] Specifically, this embodiment shows a scheme of setting the conductive metal part 50 and the scanning line 10 in different film layers. Along the thickness direction of the display panel, the conductive metal part 50 and the first end D01 of the scanning line 10 are isolated by an insulating layer, which is reflected as insulating layer J1 and insulating layer J2 in this embodiment. In this way, the distance between the conductive metal part 50 and the first end D01 of the scanning line 10 along the thickness direction of the display panel is increased, and the conditions for tip discharge between the first end D01 of the scanning line 10 and the conductive metal part 50 are destroyed, thereby avoiding the possibility of tip discharge between the first end D01 of the scanning line 10 and the conductive metal part 50, which is beneficial to further ensure the overall display effect of the display panel.

[0087] Please combine Fig. 9 and Fig.12 The display panel further includes a light shielding metal M0, which is located between the substrate 00 and the transistor T. Along the thickness direction of the display panel, the light shielding metal M0 covers the channel region of the transistor to prevent the channel region of the transistor from being affected by the backlight and causing the illumination performance to change. When the conductive metal portion 50 and the scanning line 10 are set in different film layers, the conductive metal portion 50 and the film layer where the light shielding metal M0 is located can be set in the same layer, and the scanning line 10 and the gate of the transistor can be set in the same layer. In this way, there is no need to introduce a new film layer for the conductive metal portion 50, which is conducive to simplifying the film layer structure of the display panel and improving the production efficiency of the display panel.

[0088] Optionally, when the conductive metal part 50 and the scanning line 10 are set in different film layers, the conductive metal part 50 can also be set in other metal layers in the display panel, for example, it can be set in the same layer as the data line 20, and manufactured in the same production process as the data line 20. In this way, there is no need to introduce a separate film layer for the conductive metal part 50, which is also beneficial to simplify the film layer structure of the display panel and simplify the manufacturing process of the display panel.

[0089] Fig.13 FIG. 1 is another top view of a display panel provided by an embodiment of the present invention. This embodiment shows a solution for differentially designing the line width of the conductive metal portion 50 .

[0090] Please refer to Fig.13 In an optional embodiment of the present invention, the non-display area NA includes a first non-display area NA1 arranged on one side of the display area AA along the second direction D2, and a second non-display area NA2 located on one side of the display area AA along the first direction D1, the scan line 10 includes a first end D01 and a second end D02 relatively arranged along the second direction D2, and the first end D01 is located in the first non-display area NA1; the conductive metal portion 50 includes a first conductive metal portion 51 located in the first non-display area NA1 and a second conductive metal portion 52 located in the second non-display area NA2, and in the first non-display area NA1, the first conductive metal portion 51 is located on a side of the first dummy signal line 31 away from the first end D01; the width D11 of the first conductive metal portion 51 is smaller than the width D12 of the second conductive metal portion 52.

[0091] by Fig.13For example, the first non-display area NA1 can be regarded as at least one of the left frame area and the right frame area of ​​the display panel, and the second non-display area NA2 can be regarded as the upper frame area of ​​the display panel. In the related art, when making the conductive metal part 50, the conductive metal part 50 in the first non-display area NA1 and the conductive metal part 50 in the second non-display area NA2 are usually set in an equal width manner. In the display panel provided by the embodiment of the present invention, the width of the conductive metal part 50 in the first non-display area NA1 and the second non-display area NA2 is designed differently, specifically, the width D11 of the first conductive metal part 51 located in the first non-display area NA1 is set to be smaller than the width D12 of the first conductive metal part 51 located in the second non-display area NA2. For the first conductive metal part 51, its width refers to the width of the first conductive metal part 51 along the second direction D2; for the second conductive metal part 52, its width refers to the width of the second conductive metal part 52 along the first direction D1. When the width of the first conductive metal portion 51 in the first non-display area NA1 is reduced, it is equivalent to reducing the space occupied by the first conductive metal portion 51 in the first non-display area NA1. Under the premise of ensuring that the border width of the first non-display area NA1 remains unchanged, the edge of the first conductive metal portion 51 close to the display area AA can be moved outward away from the display area AA, thereby facilitating increasing the distance between the first conductive metal portion 51 and the first end portion D01 of the scanning line 10, and further facilitating avoiding electrostatic discharge between the first conductive metal portion 51 and the first end portion D01 of the scanning line 10.

[0092] Fig.14 FIG. 1 is a diagram showing a relative position relationship among the first conductive metal portion 51 , the first dummy signal line 31 , the data line 20 , and the scan line 10 . Fig.15 Shown Fig.14 A FF cross-sectional view.

[0093] Please refer to Fig.14 In an optional embodiment of the present invention, the first dummy signal line 31 is arranged in the same layer as the data line 20; in the film layer where the first dummy signal line 31 is located, along the second direction D2, the distance D13 between the first dummy signal line 31 and other adjacent signal lines is greater than the distance D14 between two adjacent data lines 20.

[0094] Optionally, the first conductive metal portion 51 and the data line 20 are located in different film layers, and the data line 20 and the first dummy signal line 31 are located in the same film layer. In the film layer where the data line 20 is located, since the first dummy signal line 31 is the dummy signal line farthest from the data line, the other signal lines adjacent to the first dummy signal line 31 in this embodiment refer to the data line 20.

[0095] In the embodiment of the present invention, the distance D13 between the first dummy signal line 31 and the signal line adjacent thereto is set to be greater than the distance D14 between the two adjacent data lines 20, which is equivalent to moving the first dummy signal line 31 in the direction away from the display area AA along the second direction D2. When the width of the first conductive metal portion 51 in the first non-display area NA1 is reduced, it is just possible to provide a space for the first dummy signal line 31 to move outward, thereby increasing the distance between the first dummy signal line 31 and the first end D01 of the scan line 10, and avoiding the first dummy signal line 31 and the scan line 10 from overlapping in the thickness direction of the display panel. If the first end D01 of the scan line 10 is further retracted in the direction of the display area AA, it is beneficial to further increase the distance between the first end D01 of the scan line 10 and the first dummy signal line 31, further avoiding the possibility of the two overlapping, and at the same time, it can further increase the distance between the first end D01 of the scan line 10 and the first conductive metal portion 51, and avoid the phenomenon of electrostatic discharge between the first end D01 of the scan line 10 and the first conductive metal portion 51.

[0096] Optionally, the distance between the first dummy signal line 31 and other adjacent signal lines mentioned in the embodiment of the present invention refers to the width of the interval between the first dummy signal line 31 and other expected adjacent signal lines; the distance between two adjacent data lines 20 refers to the width of the interval between two adjacent data lines 20.

[0097] Fig.16 FIG. 1 is another top view of a display panel provided by an embodiment of the present invention. Fig.17 FIG. 1 is a partial enlarged view of the fourth non-display area NA4 and a portion of the display area AA adjacent to the fourth non-display area NA4 in the display panel.

[0098] Please refer to Fig.16 and Fig.17 In an optional embodiment of the present invention, the data line 20 includes a first end 201 and a second end 202 relatively arranged along a first direction D1, the display panel includes a third non-display area NA3 and a fourth non-display area NA4 arranged on both sides of the display area AA along the first direction D1, the third non-display area NA3 includes a binding area BD, the binding area BD includes a plurality of conductive pads P0; the fourth non-display area NA4 includes a plurality of detection pads P1; the first end of the data line 20 is electrically connected to the conductive pad P0, and the second end of the data line 20 is electrically connected to the detection pad P1; the data line 20 includes a first data line 21 adjacent to the dummy signal line 30, and the area of ​​the detection pad P1 connected to the first data line 21 is larger than the area of ​​the detection pad P1 connected to other data lines 20.

[0099] Specifically, the third non-display area NA3 mentioned in the present embodiment can be regarded as the lower frame area of ​​the display panel, and a binding area BD is provided in the lower frame area, and the conductive pad P0 in the binding area BD is used to bind the driver chip or the flexible circuit board. The fourth non-display area NA4 mentioned in the present embodiment can be regarded as the upper frame area of ​​the display panel, and a plurality of detection pads P1 are provided in the upper frame area, and each data line 20 is electrically connected to a detection pad P1. When the probe is brought into contact with the detection pad P1, the signal condition of the second end 202 of the data line 20 can be obtained, so that the signal of the first end 201 of the data line 20 and the signal of the second end 202 can be compared, and whether the data line 20 transmits the signal normally can be detected.

[0100] In the related art, along the arrangement direction of the detection pads P1, the distance between two adjacent detection pads P1 is equal. When the first dummy signal line 31 adjacent to the data line 20 is moved in a direction away from the display area AA, the distance between the first dummy signal line 31 and the data line 20 is increased. Assuming that the data line 20 adjacent to the dummy signal line 30 is the first data line 21, since the first dummy signal line 31 adjacent to the first data line 21 is moved outward, the distance between the first dummy signal line 31 and the first data line 21 is increased, thereby providing a space for increasing the area of ​​the detection pad P1 connected to the first data line 21, and the area of ​​the detection pad P1 connected to the first data line 21 can be increased. When a probe is electrically connected to the detection pad P1 to detect a signal on the first data line 21, the larger the area of ​​the detection pad P1, the lower the difficulty of electrical connection between the probe and the detection pad P1, which is conducive to improving the detection efficiency.

[0101] Optionally, the dummy signal line 30 is also electrically connected to the detection pad P1, so as to ensure the visual uniformity of the display panel. Of course, in some other embodiments of the present invention, if the dummy signal line 30 is in a floating state, the detection pad may not be set for the dummy signal line 30. For example, please refer to Fig.18 , Fig.18 FIG. 1 is another partial enlarged view of the fourth non-display area NA4 and a portion of the display area AA adjacent to the fourth non-display area NA4 in the display panel.

[0102] Fig.19 FIG. 1 is another top view of a display panel provided by an embodiment of the present invention. Fig. 20 FIG. 1 is another partial enlarged view of the fourth non-display area NA4 and a portion of the display area AA adjacent to the fourth non-display area NA4 in the display panel.

[0103] Please refer to Fig.19 and Fig. 20In an optional embodiment of the present invention, the display panel further includes a conductive metal portion 50 located in the non-display area NA, and the conductive metal portion 50 is at least partially arranged around the display area AA; in the non-display area NA, the conductive metal portion 50 is located on a side of the first dummy signal line 31 away from the display area AA, the conductive metal portion 50 receives a fixed potential signal, and the conductive metal portion 50 is electrically connected to the first dummy signal line 31;

[0104] The data line 20 includes a first end 201 and a second end 202 that are relatively arranged along a first direction D1. The display panel includes a third non-display area NA3 and a fourth non-display area NA4 that are arranged on both sides of the display area AA along the first direction D1. The third non-display area NA3 includes a binding area BD, and the binding area BD includes a plurality of conductive pads P0; the fourth non-display area NA4 includes a plurality of detection pads P1; the first end 201 of the data line 20 is electrically connected to the conductive pad P0, and the second end 202 of the data line 20 is electrically connected to the detection pad P1;

[0105] The first dummy signal line 31 is electrically connected to the detection pad P1 in the fourth non-display area NA4 , and the area of ​​the detection pad P1 connected to the first dummy signal line 31 is larger than the area of ​​the detection pad P1 connected to the data line 20 .

[0106] Specifically, the present embodiment shows a scheme of reusing the dummy signal line 30 (first dummy signal line 31) closest to the conductive metal part 50 as a common signal line connected to the conductive metal part 50, and the first dummy signal line 31 is electrically connected to the conductive metal part 50, and is used to transmit the common signal on the conductive metal part 50 to the sub-pixel in the display area. At this time, there is no need to introduce an additional signal line in the display panel to be electrically connected to the conductive metal part 50, which is conducive to simplifying the wiring of the display panel. In the related art, along the arrangement direction of the detection pads P1, the distance between two adjacent detection pads P1 is equal. When the first dummy signal line 31 is moved in a direction away from the display area AA, the distance between the first dummy signal line 31 and the data line 20 is increased, thereby providing a space for increasing the area of ​​the detection pad P1 connected to the first dummy signal line 31, so that the area of ​​the detection pad P1 connected to the first dummy signal line 31 can be increased. When a probe is electrically connected to the detection pad P1 to detect the signal on the first dummy signal line 31 , the larger the area of ​​the detection pad P1 is, the lower the difficulty of the electrical connection between the probe and the detection pad P1 can be, thus facilitating improving detection efficiency.

[0107] It should be noted that Fig. 20 The embodiment only shows a solution in which one dummy signal line 30 is provided in the non-display area on the same side of the display area. In some other embodiments of the present invention, two or more dummy signal lines 30 may be provided in the non-display area NA on the same side of the display area AA. For example, please refer to Fig.21 ,in, Fig.21 Shown is another partial enlarged view of the fourth non-display area NA4 and a portion of the display area AA adjacent to the fourth non-display area NA4 in the display panel. This embodiment shows a solution in which two dummy signal lines 30 are provided in the non-display area NA on the same side of the display area AA. At this time, the first dummy signal line 31 located at the outermost periphery can be reused as a common signal line to be electrically connected to the conductive metal part.

[0108] It should be noted that the display area mentioned in the embodiment of the present invention is an area where sub-pixels that can actually play a display role are arranged. Compared with the data lines in the display area, the dummy signal lines are not electrically connected to the sub-pixels in the display area, and the dummy signal lines are located in the non-display area.

[0109] Fig. 22 FIG. 1 is a schematic diagram showing a connection between a scan line 10 and a sub-pixel in a display panel.

[0110] Please refer to Fig. 22 In an optional embodiment of the present invention, the display panel includes a plurality of sub-pixels P arranged in an array along a first direction D1 and a second direction D2; among the sub-pixels P located in the same row along the second direction D2, some of the sub-pixels P are electrically connected to a scan line 10 / G1, and another part of the sub-pixels P are electrically connected to another scan line 10 / G2; the scan line 10 includes a first end D01 and a second end D02 opposite to each other along the second direction D2, and the first ends D01 of the two scan lines 10 connected to the sub-pixels P in the same row are both located between the first dummy signal line 31 and the second end D02.

[0111] Specifically, this embodiment shows a scheme in which sub-pixels P located in the same row are connected to two scanning lines 10. For this scheme, two adjacent columns of sub-pixels can be connected to the same data line 20. Compared with the method in the related art in which one column of sub-pixels corresponds to one data line 20, the number of data lines 20 included in the display panel is greatly reduced, and the cost of the driving circuit (IC) connecting the data lines 20 is also reduced accordingly, thereby reducing the cost of the product.

[0112] When a row of sub-pixels is electrically connected to two scan lines 10, compared with a connection method in which a row of sub-pixels corresponds to one scan line 10, the number of scan lines 10 in the display panel is increased. When the first end D01 of the scan line 10 is close to the signal line 40 in the non-display area NA, tip discharge is very likely to occur. The more the number of scan lines 10, the greater the possibility of tip discharge, and the greater the possibility of electrical connection between the scan line 10 and the first virtual signal line 31 due to static electricity. To this end, in the embodiment of the present invention, the first end D01 of each scanning line 10 is arranged between the first dummy signal line 31 and the second end D02, that is, the scanning line 10 and the first dummy signal line 31 have no overlap in the thickness direction of the display panel, and at the same time, the distance between the first end D01 of the scanning line 10 and the signal line 40 in the non-display area NA is increased. In this way, even if the display panel includes a large number of scanning lines 10, the possibility of tip discharge between the first end D01 of the scanning line 10 and the signal line 40 can be reduced. At the same time, the situation where electrical connection occurs between the scanning line 10 and the first dummy signal line 31 due to electrostatic breakdown can be avoided, which is beneficial to ensuring the overall display effect of the display panel.

[0113] Fig.23 FIG. 1 is another schematic diagram of the structure of a display panel provided in an embodiment of the present invention.

[0114] Please refer to Fig.23 In an optional embodiment of the present invention, the scan line 10 includes a first end D01 and a second end D02 opposite to each other along the second direction D2, and the first end D01 is located between the first dummy signal line 31 and the data line 20; the display panel also includes a gate driving chip 80 arranged in the non-display area NA, and the second end D02 is electrically connected to the gate driving chip 80.

[0115] This embodiment shows a way for the scan line 10 to obtain a scan signal. Specifically, a gate drive chip 80 is provided in the non-display area NA of the display panel. The gate drive chip 80 can be provided in the non-display area NA on one side of the display area AA along the second direction D2. This embodiment is described by taking the gate drive chip 80 as an example to be located at the right frame of the display panel. The second end D02 of the scan line 10 is electrically connected to the gate drive chip 80, and the scan signal is obtained through the gate drive chip 80. The first end D01 of the scan line 10 can be located in another non-display area NA opposite to the gate drive chip 80, for example, in the left frame of the display panel. Further, the first end D01 of the scan line 10 is located between the first dummy signal line 31 and the data line 20, thereby avoiding the overlap of the scan line 10 and the first dummy signal line 31 in the thickness direction of the display panel, thereby avoiding the problem of connection between the scan line 10 and the first dummy signal line 31 due to electrostatic breakdown, so it is beneficial to avoid the generation of dark lines and ensure the overall display effect of the display panel.

[0116] Fig.24 FIG. 1 is another schematic diagram of the structure of a display panel provided in an embodiment of the present invention.

[0117] Please refer to Fig.24 In an optional embodiment of the present invention, the scan line 10 includes a first end D01 and a second end D02 opposite to each other along the second direction D2, and the first end D01 is located between the first dummy signal line 31 and the data line 20; the display panel also includes a cascaded gate drive circuit VSR, the gate drive circuit VSR is located in the non-display area NA, and the second end D02 of the scan line 10 is electrically connected to the gate drive circuit VSR. Optionally, the first end D01 can be regarded as an end of the scan line 10 that is not directly connected to the gate drive circuit VSR, and the first end D01 obtains the signal transmitted by the gate drive circuit VSR through the second end D02.

[0118] Specifically, the embodiment of the present invention shows a scheme for electrically connecting the scan line 10 to the gate drive. In the non-display area NA on one side of the display area AA along the second direction D2, a cascaded gate drive circuit VSR is provided. In the same scan line 10, its second end D02 is electrically connected to the gate drive circuit VSR, and the first dummy signal line 31 adjacent to its first end D01 is provided in another non-display area NA opposite to the non-display area NA where the gate drive circuit VSR is located. In this embodiment, the scan line 10 obtains the scan signal through the cascaded gate drive circuit VSR. In the first scan line G1, the first end D01 that is not directly connected to the gate drive circuit VSR is located between the first dummy signal line 31 and the data line 20, which can also increase the distance between the first end D01 of the scan line 10 and the signal line 40 in the non-display area NA, avoiding the overlap of the first end D01 and the first dummy signal line 31 in the thickness direction of the display panel, thereby avoiding static electricity causing the first dummy signal line 31 to be electrically connected to the scan line 10 and affecting the overall display effect of the display panel.

[0119] In an optional implementation of the present invention, the output end of the gate driving circuit VSR is electrically connected to the second end D02 of the scan line 10 through a connection hole, and the second end D02 is located between the first dummy signal line 31 and the data line 20 .

[0120] When the second end D02 of the scanning line 10 is electrically connected to the output end of the gate driving circuit VSR through the connecting hole, if there is a signal line 40 arranged in the same layer as the scanning line 10 in the non-display area NA, at this time, the signal line 40 may be, for example, some signal lines connected to the gate driving circuit VSR, and electrostatic discharge may also occur between the second end D02 of the scanning line 10 and the above-mentioned signal line 40. If the second end D02 of the scanning line 10 overlaps with the first dummy signal line 31 in the non-display area NA, static electricity may also cause a connection between the scanning line 10 and the first dummy signal line 31, resulting in abnormal display of the display panel. Therefore, in the present embodiment, the second end D02 of the scanning line 10 is arranged between the first dummy signal line 31 and the data line 20, so as to increase the distance between the second end D02 and the first dummy signal line 31, and at the same time increase the distance between the second end D02 and the signal line 40 in the non-display area NA, thereby reducing the possibility of tip discharge between the second end D02 and the signal line 40, and at the same time avoiding the overlap of the scanning line 10 and the first dummy signal line 31 in the thickness direction of the display panel, which is beneficial to avoid the phenomenon of connection between the scanning line 10 and the first dummy signal line 31 caused by electrostatic breakdown, and is beneficial to ensure the display effect of the display panel.

[0121] Please refer to Fig.24In an optional embodiment of the present invention, the gate driving circuit VSR is located in the non-display area NA on the same side of the display area AA along the second direction D2;

[0122] Alternatively, please refer to Fig.25 The gate drive circuit VSR is distributed in the non-display area NA on both sides of the display area AA along the second direction D2. The odd-numbered scan lines 10 are electrically connected to the gate drive circuit VSR on the same side of the display area AA, and the even-numbered scan lines 10 are electrically connected to the gate drive circuit VSR on the other side of the display area AA. Fig.25 FIG. 1 is another schematic diagram of the structure of a display panel provided in an embodiment of the present invention.

[0123] Specifically, when the scan line 10 obtains the scan signal by connecting to the gate drive circuit VSR, the gate drive circuit VSR connected to each scan line 10 in the display panel may be located in the non-display area NA on the same side of the display area AA along the second direction D2. Fig.24 The second end D02 of each scan line 10 is electrically connected to the gate drive circuit VSR, and the first end D01 of each scan line 10 is located on the same side of all the data lines 20 in the display area AA. In this way, when part of the line segments in the scan line 10 are removed so that the first end D01 is located between the first dummy signal line 31 and the data line 20, one end of each scan line 10 located on the same side of the data line 20 can be uniformly processed, so that the first end D01 of each scan line 10 is located between the same first dummy signal line 31 and the data line 20, avoiding the first scan line G1 and the first dummy signal line 31 from overlapping in the thickness direction of the display panel. The method of uniformly processing one end of the data line 20 located on the same side of the data line is conducive to simplifying the manufacturing process of the scan line 10 in the display panel.

[0124] In some other embodiments of the present invention, for example, please refer to Fig.25 , the gate driving circuit VSR connected to the scan line 10 can also be distributed in the two side frames of the display panel. When the gate driving circuit VSR is electrically connected to the scan line 10, the gate driving circuit VSR located on the first side of the display area AA along the second direction D2 is connected to the scan line 10 of the odd rows, and the gate driving circuit VSR located on the second side of the display area AA along the second direction D2 is connected to the scan line 10 of the even rows. In this way, it is equivalent to evenly distributing the gate driving circuit VSR on the two side frame areas of the display panel, which is beneficial to improving the width uniformity of the two side frames of the display panel.

[0125] Fig.26 Shown Fig.14Another FF-direction cross-sectional view of the display panel, this embodiment shows a differentiated design solution of the first insulating layer J1 in the first non-display area NA1 and the display area AA.

[0126] Please refer to Fig.26 In an optional embodiment of the present invention, the non-display area NA includes a first non-display area NA1 located on at least one side of the display area AA along the second direction D2; along a direction perpendicular to the plane where the substrate is located, a first insulating layer J1 is arranged between the film layer where the scanning line 10 is located and the film layer where the dummy signal line 30 is located; in the first non-display area NA1, the thickness of the first insulating layer J1 is S1, and in the display area AA, the thickness of the first insulating layer J1 is S2, wherein S1>S2.

[0127] Specifically, since the first dummy signal line 31 is arranged in the non-display area NA, when the thickness of the first insulating layer J1 in the non-display area NA is made larger, for example, larger than the thickness of the first insulating layer J1 in the display area AA, the distance between the first dummy signal line 31 and the scanning line 10 along the thickness direction of the display panel can be increased. Even if there is electrostatic interference, since the longitudinal distance between the first dummy signal line 31 and the scanning line 10 is large, it is difficult for static electricity to break through the thicker first insulating layer J1, which is beneficial to further avoid the display dark line caused by the point electrical connection between the first dummy signal line 31 and the scanning line 10 due to static electricity, so it is beneficial to ensure the display effect of the display panel.

[0128] Continue to refer Fig.26 In an optional embodiment of the present invention, the thickness of the film layer where the dummy signal line 30 is located is S0, wherein S0≥S1-S2. The dummy signal line 30 is arranged on the side of the first insulating layer J1 away from the substrate. When the problem of the first dummy signal line 31 being electrically connected to the scan line 10 due to static electricity is avoided by increasing the thickness of the first insulating layer J1 in the first non-display area NA1, the present invention further defines that the difference in thickness between the first insulating layer J1 in the first non-display area NA1 and the first insulating layer J1 in the display area AA is less than or equal to the thickness S0 of the film layer where the dummy signal line 30 is located. In this way, even if there is a height difference between the first insulating layer J1 in the display area AA and the first non-display area NA1, when a metal routing (such as the dummy signal line 30 and the data selection 20) is made on the first insulating layer J1, if the metal routing is formed in an area with a height difference, the thickness of the metal routing can also make up for the above-mentioned height difference, that is, the metal routing arranged in the area with a height difference will not be disconnected, which is conducive to ensuring the reliability of signal transmission of the metal routing arranged on the first insulating layer J1.

[0129] Based on the same inventive concept, the present invention also provides a display device, Fig. 27FIG. 2 is a schematic diagram of a structure of a display device provided in an embodiment of the present invention. The display device 200 includes the display panel 100 provided in the above embodiment of the present invention.

[0130] It is understandable that the display device provided in the embodiment of the present invention may be a computer, a mobile phone, a tablet or other display device with a display function. The present invention does not specifically limit this. The display device provided in the embodiment of the present invention has the beneficial effects of the display panel provided in the embodiment of the present invention. For details, please refer to the specific description of the display panel in the above embodiments, which will not be repeated in this embodiment.

[0131] It can be seen from the above embodiments that the display panel and the display device provided by the present invention achieve at least the following beneficial effects:

[0132] The display panel and the display device provided by the embodiment of the present invention include cross-arranged scan lines and data lines, wherein the data lines extend along a first direction, the scan lines extend along a second direction, the data lines are located in the display area, and are used to provide data signals for sub-pixels, and the scan lines are used to provide scan signals for sub-pixels. A dummy signal line is arranged in the non-display area, and the dummy signal line is parallel to the data line, wherein the dummy signal line farthest from the data line is the first dummy signal line. Since the extension direction of the scan line overlaps with the data line, the end of the scan line is very likely to extend to the non-display area. When a metal signal line is arranged in the non-display area, a tip discharge phenomenon is very likely to occur at the end of the scan line. If the end overlaps with the first dummy signal line in the thickness direction of the display panel, the static electrode is likely to break through the insulating layer between the end of the scan line and the first dummy signal line, resulting in the scan line being electrically connected to the first dummy signal line, thereby affecting the normal display of the sub-pixel connected to the scan line. Therefore, the present invention arranges the end of the scanning line between the first dummy signal line and the data line to avoid overlapping of the end of the scanning line and the first dummy signal line in the thickness direction of the display panel. This can not only increase the distance between the end of the scanning line and the edge of the non-display area along the second direction and reduce the possibility of tip discharge, but also avoid the phenomenon that the end of the scanning line is electrically connected to the first dummy signal line which may be caused by tip discharge, thereby avoiding the problem of display abnormality caused by the electrical connection between the scanning line and the first dummy signal line, so it is beneficial to avoid the influence of static electricity on the display effect.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
