[0031] Figure 1 is a schematic diagram of a touch display panel in the prior art. As Figure 1 shown, the touch display panel includes a substrate 10' and a touch layer 20' provided on one side of the substrate 10'. The substrate 10' includes a display area 11' and a non-display area 12' surrounding the display area 11'.

[0032] The touch layer 20' includes a plurality of touch electrodes 21' arranged in an array and touch leads 22' electrically connected to the touch electrodes 21'. The touch leads 22' are used to transmit touch signals to the touch electrodes 21'. The touch electrodes 21' are disposed in the display area 11'. The touch electrodes 21' include a first touch electrode 211' and a second touch electrode 212'. The first touch electrodes 211' are connected in the first direction X to form a first electrode string, and the second touch electrodes 212' are connected in the second direction Y to form a second electrode string. The touch leads 22' include a first touch lead 221' and a second touch lead 222'. Two ends of the first touch lead 221' are respectively connected to the first electrode string and the touch chip 30', and two ends of the second touch lead 222' are respectively connected to the second electrode string and the touch chip 30'. The first touch lead 221' and the second touch lead 222' extend from the display area 11' to the non-display area 12'.

[0033] Please continue to refer to Figure 1 , there is a large interval space on the side border non-display area for the first touch leads 221' connecting different first electrode strings, and there is a large interval space on the lower border non-display area for the second touch leads 222' connecting different second electrode strings. That is, currently, the touch leads 22' are unevenly routed in the non-display area 12'. The uneven routing of the touch leads 22' will affect the etching uniformity when etching the touch leads 22'. To arrange the touch leads 22' at uniform intervals, usually, floating lines 40' are set in these interval spaces or the width of the touch leads 22' is increased in the interval spaces.

[0034] Figure 2 is a schematic diagram of setting floating lines at the lower border of a touch display panel in the prior art. As Figure 2 shown, the touch electrodes 21' are arranged in the display area 11', part of the touch leads 22' extend to the non-display area 12', and the interval distance between some touch leads 22' is too large. Therefore, a plurality of floating lines 40' are set in the interval area between the two touch leads 22' to ensure that the touch leads 22' are evenly distributed on the lower border of the display panel.

[0035] Figure 3 is a schematic diagram of setting floating lines at the side border of a touch display panel in the prior art. As Figure 3 shown, the touch electrodes 21' are arranged in the display area 11', part of the touch leads 22' extend to the non-display area 12', and a plurality of floating lines 40' are set in the interval area between the two touch leads 22' to ensure that the touch leads 22' are evenly distributed on the side border area of the display panel. The floating lines 40' are wires that do not transmit signals. The floating lines 40' will accumulate charges. When the charges accumulated on the floating lines 40' exceed the critical value, electrostatic injury will occur, which will affect the reliability of the touch panel.

[0036] Figure 4 is a schematic diagram of the widened design of the touch lead in the prior art. As Figure 4 shown, the width d1' of the first end 22a' of one of the touch leads 22' of the touch display panel is smaller than the width d2' of its second end 22b'. By widening the design of the touch lead 22', the spacing between the two touch leads 22' is reduced, so that the touch lead 22' is evenly wired on the non-display area 12'. However, the sudden change in the line width design of the touch lead 22' is also a weak point of electrostatic injury, and it is easy to have an electrostatic injury problem at the sudden change in line width; and the sudden change in the line width design of the touch lead 22' will also affect the optical stability of the display panel. Therefore, the design of the floating line 40' between the adjacent touch leads 23' and the widened design of the line width of the touch lead 23' in the existing touch display panel will both affect the reliability of the touch panel.

[0037] To solve the above technical problems, an embodiment of the present application provides a touch display panel, which includes a substrate and a touch layer. The substrate includes a display area and a non-display area surrounding at least one side of the display area; the touch layer is disposed on one side of the substrate, and the touch layer includes a plurality of touch electrodes arranged in an array and touch leads electrically connected to the touch electrodes, and the touch leads are used to provide touch signals to the touch electrodes; the touch leads extend from the display area to the non-display area; in the non-display area, there is a spacing area between at least some adjacent two touch leads; the touch electrodes extend from the display area to the spacing area.

[0038] In this technical solution, by extending the touch electrodes from the display area to the non-display area, it is used to improve the problem that the spacing between some adjacent two touch leads is too large, make the gap between the touch leads uniform, and then improve the uniformity of etching the touch leads. Correspondingly, the design of the floating line and the sudden change in the line width of the touch lead can be cancelled, the weak points of electrostatic injury can be reduced, the anti-electrostatic ability of the touch display panel can be improved, and the reliability of the touch display panel can be improved; and the touch electrodes extend outside the display area, and correspondingly, the touch performance at the edge of the touch display panel can also be improved, ensuring the user experience.

[0039] Next, the touch display panel in the specific embodiment will be introduced with reference to the drawings. It can be understood that the drawings and the following description are only examples and do not limit the protection scope of the present application.

[0040] Figure 5 is a schematic diagram of the touch display panel provided by an embodiment of the present application; Figure 6 is a partial schematic diagram of the touch display panel provided by an embodiment of the present application; Figure 7 is a partial schematic diagram of the touch display panel provided by another embodiment of the present application. Combining Figures 5 to 7 it can be obtained that the touch display panel includes a substrate 10 and a touch layer 20.

[0041] Specifically, the substrate 10 includes a display area 11 and a non-display area 12 surrounding at least one side of the display area 11.

[0042] Exemplarily, in this embodiment, the substrate 10 is rectangular, but in some other embodiments, the substrate 10 can also be square, oval, circular, etc., or can be an irregular shape. The specific shape of the substrate 10 is set according to actual requirements.

[0043] The display area 11 specifically includes a plurality of pixel areas (not shown in the figure) distributed in an array. Each pixel area includes a plurality of adjacent sub-pixel areas. Light-emitting elements of the same or different colors are arranged in the plurality of sub-pixel areas to achieve monochromatic or color display. The light-emitting elements can be, for example, red light-emitting elements, green light-emitting elements, blue light-emitting elements, or white light-emitting elements.

[0044] The non-display area 12 is the border area of the display panel. Exemplarily, in this embodiment, the touch display panel includes an upper border, a lower border, a left border, and a right border. The width of the lower border is greater than the widths of the upper border, the left border, and the right border. In some other embodiments, for example, the touch display panel only includes an upper border and a lower border, and the width of the lower border is greater than the width of the upper border; in some other embodiments, the touch panel can also be set such that the width of the lower border is equal to the widths of the other borders. It should be noted that the shape of the display panel, the number of borders, and the width settings are not specifically limited here and can be set according to actual requirements.

[0045] Further, please continue to refer to Figure 5 , the touch layer 20 includes touch electrodes 21 and touch leads 22 for transmitting touch signals to the touch electrodes 21; the touch leads extend from the display area 11 to the non-display area 12. In the non-display area 12, an interval area is provided between some adjacent two touch leads 22, and the touch electrodes 21 extend from the display area 11 to the non-display area 12. Exemplarily, as Figure 5 shown, there are touch electrodes 21 on the left border, right border, and lower border of the display panel.

[0046] By extending the touch electrodes 21 from the display area 11 to the non-display area 12, it is used to improve the problem that the distance between some adjacent two touch leads 22 is too large, make the gaps between the touch leads 22 uniform, and further improve the uniformity of etching the touch leads 22. Correspondingly, the design of floating lines and the design of sudden changes in the line width of the touch leads can be cancelled, the weak points of electrostatic shock are reduced, the antistatic ability of the touch display panel is improved, and the reliability of the touch display panel is improved; and the touch electrodes 21 extend out of the display area 11, and correspondingly, the touch performance at the edge of the touch display panel can also be improved, ensuring the user experience.

[0047] Further, the material of the substrate 10 may be a rigid substrate or a flexible substrate. The material of the rigid substrate may be glass, quartz, etc.; the material of the flexible substrate may be polyimide (PI), polyethylene terephthalate, polydimethylsiloxane (PDMS), etc.

[0048] When manufacturing a rigid display panel, usually a small-sized panel is first cut from a large-sized panel and then packaged. This allows for flexible subsequent packaging processes, improves production efficiency, and the cut-then-package process can also reduce material waste and lower production costs. When manufacturing a flexible display panel, usually packaging is carried out first and then cutting. During the cutting process of the flexible display panel, it may be affected by mechanical stress. Packaging first can protect the display device from damage during cutting, and packaging first can make the flexible display panel have better stability and reliability, effectively improving the product yield. Therefore, when the touch display panel is a rigid display panel, the spacer region does not exceed the cutting edge of the display panel, and when the touch display panel is a flexible display panel, the spacer region does not exceed the edge packaging region of the display panel.

[0049] Further, as Figure 6 shown, in some embodiments, the non-display area 12 includes a first non-display area 121, and the first non-display area 121 is provided on the first side of the display area 11; the spacer region includes a first spacer region 1211, and the first spacer region 1211 is provided on the first non-display area 121. Here, the first non-display area 121 is the lower border area of the substrate 10.

[0050] By extending the touch electrode 21 from the display area 11 to the lower border area of the substrate 10, the problem of excessive spacing between some adjacent two touch leads 22 at the lower border is improved, making the gaps between the touch leads 22 uniform, thereby improving the uniformity of etching the touch leads 22. Correspondingly, the design of floating lines and the design of sudden changes in the line width of the touch leads can be cancelled, reducing the weak points of electrostatic shock damage and improving the antistatic ability of the touch display panel and the reliability of the touch display panel; and the touch electrode 21 extends to the lower border of the panel, correspondingly, the touch performance of the lower border of the panel can also be improved, ensuring the user experience.

[0051] Further, the size of the first spacer region 1211 in the second direction Y is h1, and h1 is less than 1000 μm.

[0052] As Figure 7 shown, in some embodiments, the non-display area 12 further includes a second non-display area 122, and the second non-display area 122 is provided on the second side of the display area 11; the spacer region includes a second spacer region 1221, and the second spacer region 1221 is provided on the second non-display area 122. Here, the second non-display area is the side border area of the substrate 10.

[0053] By expanding the touch electrode 21 to the side border area of the substrate 10, the problem of excessive distance between some adjacent two touch leads 22 at the side border is improved, making the gaps between the touch leads 22 uniform, thereby improving the etching uniformity of the touch leads 22. Correspondingly, the design of the floating line and the design of the sudden change in the line width of the touch leads 22 can be cancelled, reducing the weak points of electrostatic shock, improving the antistatic ability of the touch display panel, and improving the reliability of the touch display panel; the touch electrode 21 extends to the side border of the panel, and correspondingly, the touch performance of the panel side border can also be improved, ensuring the user experience.

[0054] Further, in some embodiments, the size of the second interval region 1221 along the first direction X is h2, and the range of h2 is 50 μm to 75 μm.

[0055] As Figure 6 and Figure 7 shown, in some embodiments, the touch electrode 21 is designed as a grid-like structure, which can reduce the occlusion of the display area 11 and improve the display effect of the panel. However, the structure of the touch electrode 21 is not limited thereto, and it can also be set to other structures that meet the requirements.

[0056] Further, as Figure 5 shown, in some embodiments, the touch display panel further includes a touch chip 30, and each touch electrode 21 is electrically connected to the touch chip 30 through a touch lead 22. The touch chip 30 is used for touch detection. When performing touch detection, it respectively determines the horizontal coordinate and the vertical coordinate according to the change in capacitance before and after touch, and then combines them into a planar touch coordinate, thereby measuring the touch position. Further, the touch technology includes mutual capacitance touch technology and self-capacitance touch technology.

[0057] Please continue to refer to Figure 5 , in some embodiments, multiple touch electrodes 21 form multiple first touch electrode strings distributed along the second direction Y and multiple second touch electrode strings distributed along the first direction X. The first touch electrode string includes multiple first touch electrodes 211 extending along the first direction, and the second touch electrode string includes multiple second touch electrodes 212 extending along the second direction Y. The touch leads 22 include first touch leads 221 and second touch leads 222. Each first touch electrode string is electrically connected to the touch chip 30 through a first touch lead 221, and each second touch electrode string is electrically connected to the touch chip 30 through a second touch lead 222.

[0058] As Figure 5As shown, in some embodiments, there is a spacing region between at least one pair of adjacent first touch leads 221, that is, there is a relatively large gap between adjacent first touch leads 221. Exemplarily, the second touch electrode 212 extends into the non-display area 12 to narrow the gap between adjacent first touch leads 221 and make the distribution of the first touch leads 221 uniform.

[0059] As Figure 5 shown, in some embodiments, there is a spacing region between at least one pair of adjacent second touch leads 222, that is, there is a relatively large gap between adjacent second touch leads 222. Exemplarily, the first touch electrode 211 extends into the non-display area 12 and is electrically connected to the first touch lead 221 to narrow the gap between adjacent second touch leads 222 and make the distribution of the second touch leads 222 uniform.

[0060] Figure 8 and Figure 9 respectively show schematic structural diagrams of two touch display panels. As Figure 8 shown, the first touch electrode 211 and the second touch electrode 212 are arranged in the same layer; as Figure 9 shown, the first touch electrode 211 and the second touch electrode 212 are arranged in different layers, and an insulating layer 23 is provided between the first touch electrode 211 and the second touch electrode 212. The manufacturing material of the insulating layer 23 includes one or a combination of inorganic insulating layer materials and organic insulating materials.

[0061] In this embodiment, the touch display panel is a mutual capacitance touch display panel. Multiple first touch electrodes 211 in the first touch electrode string are electrically connected through a first jumper wire, and multiple second touch electrodes 212 in the second touch electrode string are electrically connected through a second jumper wire. The first jumper wire and the second jumper wire are arranged in different layers. The overlapping portion of the first touch electrode 211 and the second touch electrode forms a capacitive structure, and the capacitive structure can generate corresponding touch signals according to the user's touch situation.

[0062] When the first touch electrode 211 and the second touch electrode 212 are arranged in the same layer, the first jumper wire and the second jumper wire are arranged in different layers. The first jumper wire can be in the same layer as the first touch electrode 211 and the second touch electrode 212, and the second jumper wire is arranged in another layer. When the first touch electrode 211 and the second touch electrode 212 are arranged in different layers, the first jumper wire can be arranged in the same layer as the first touch electrode 211, and the second jumper wire can be arranged in the same layer as the second touch electrode 212. The specific type and structure of the touch electrode can be set according to actual needs and are not specifically limited here.

[0063] According to an embodiment of the present invention, the specific working principle of mutual capacitance touch is as follows: The touch chip 30 outputs a scanning signal to one of the first touch electrode string or the second touch electrode string through the first touch lead 221 or the second touch lead 222, and the touch chip 30 controls the other touch electrode string to receive the signal, that is, one of the first touch electrode 211 and the second touch electrode 212 serves as a scanning electrode, and the other serves as a receiving electrode. The touch chip 30 confirms the touch position by detecting the capacitance change between the first touch electrode 211 and the second touch electrode 212, and performs position reporting.

[0064] In another embodiment, the touch display panel can also be set as a self - capacitance touch display panel. The touch chip 30 sequentially outputs scanning signals to the touch electrode 21 along the first direction X and the second direction Y. The touch electrode 21 forms a capacitance with the ground. The touch chip 30 confirms the touch position by detecting the capacitance change of the touch electrode 21 with respect to the ground, and performs position reporting.

[0065] An embodiment of the present application also provides a display device, including the touch display panel as described above. Figure 10 The schematic diagram of the display device provided by an embodiment of the present invention is shown. As Figure 10 shown, the display device 1000 includes the touch display panel as described above, so all technical effects of the display panel can be obtained, which will not be elaborated here. Specifically, the display device 1000 can be any device that displays whether it is moving (e.g., video) or stationary (e.g., still image), and whether it is text or image. More specifically, it is expected that the embodiments can be implemented in or associated with a variety of electronic devices. The variety of electronic devices include, for example (but not limited to), mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, video cameras, game consoles, watches, clocks, calculators, television monitors, flat panel displays, computer monitors, automotive displays, electronic photos, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures, etc.

[0066] In summary, the touch display panel and the display device provided by the embodiments of the present application have the following advantages:

[0067] The touch electrodes extend from the display area to the non - display area, which is used to improve the problem that the distance between some adjacent two touch leads is too large, make the gaps between the touch leads uniform, and then improve the etching uniformity of the touch leads. Correspondingly, the design of floating lines and the design of sudden changes in the line width of the touch leads can be cancelled, the weak points of electrostatic shock are reduced, the antistatic ability of the touch display panel is improved, and the reliability of the touch display panel is improved; and the touch electrodes extend outside the display area, and correspondingly, the touch performance at the edge of the touch display panel can also be improved, ensuring the user experience.

[0068] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present invention.
