Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a touch display panel and a display device. BACKGROUND

[0002] The touch display panel comprises a touch panel and a display panel, realizes compatibility of picture display and user interaction, and improves user experience.

[0003] The touch display panel comprises a display area and a non-display area, wherein the non-display area comprises an encapsulation area, the display panel is provided with complex metal traces in the encapsulation area, light cannot penetrate due to the opacity of the metal traces, thereby causing a large difference in laser transmittance between different regions of the bonding area. The touch panel has an opaque metal pattern in the encapsulation area, and the opaque metal pattern in the encapsulation area on the touch panel will shield the gap between the metal traces in the encapsulation area on the display panel after the touch panel and the display panel are stacked, which will further increase the complexity of the overall light transmittance of the encapsulation area of the touch display panel, thereby causing poor encapsulation reliability of the touch display panel and affecting product yield. SUMMARY

[0004] In view of the above problems, the present application provides a touch display panel and a display device, which can effectively improve the encapsulation reliability of the touch display panel and improve the product yield.

[0005] In a first aspect, an embodiment of the present application provides a touch display panel, which comprises a display area and a non-display area, and further comprises a display panel and a touch panel. The display panel comprises a first encapsulation area in the non-display area, and the first encapsulation area is provided with opaque metal traces and gaps outside the opaque metal traces. The touch panel is stacked with the display panel, and the touch panel comprises a second encapsulation area in the non-display area and corresponding to the first encapsulation area. The second encapsulation area comprises a first metal layer, and the first metal layer comprises a first opaque metal pattern. The projection of the first opaque metal pattern on the display panel in a direction perpendicular to the display panel does not overlap with the gap.

[0006] By adjusting the first opaque metal pattern in the first encapsulation area on the touch panel, the projection of the first opaque metal pattern on the display panel in a direction perpendicular to the display panel does not overlap with the gap between the opaque metal traces in the second encapsulation area on the display panel. Therefore, after the touch panel and the display panel are stacked, the first opaque metal pattern in the first encapsulation area on the touch panel will not shield the gap between the opaque metal traces in the second encapsulation area on the display panel, thereby reducing the complexity of the overall light transmittance of the encapsulation area of the touch display panel, effectively improving the encapsulation reliability of the touch display panel, and improving the product yield.

[0049] The touch display panel includes a touch panel and a display panel, realizes the compatibility of picture display and user interaction, and improves the user experience.

[0050] The inventors of the present application have noticed that the touch display panel includes a display area and a non-display area, wherein the non-display area includes a packaging area, the display panel is provided with complex metal traces in the packaging area, and since the metal traces are not light-transmissive, the difference in laser transmission rate between different regions of the packaging area is large. The touch panel has a non-light-transmissive metal pattern in the packaging area, and after the touch panel and the display panel are laminated, the non-light-transmissive metal pattern in the packaging area on the touch panel will shield the gap between the metal traces in the packaging area on the display panel, which will further increase the complexity of the overall light transmittance of the packaging area of the touch display panel, and thus the packaging reliability of the touch display panel is poor, which affects the product yield.

[0051] The inventors of the present application have found that by adjusting the opaque metal pattern in the packaging area on the touch panel, the projection of the opaque metal pattern on the display panel in the direction perpendicular to the display panel does not overlap the gap between the metal traces in the packaging area on the display panel. Therefore, after the touch panel and the display panel are stacked, the opaque metal pattern in the packaging area on the touch panel does not block the gap between the metal traces in the packaging area on the display panel, thereby reducing the complexity of the overall packaging area light transmittance of the touch display panel, effectively improving the packaging reliability of the touch display panel, and improving product yield.

[0052] To solve the problems in the prior art, the embodiments of the present application provide a touch display panel and a display device, which can improve the packaging reliability of the touch display panel and improve product yield. First, the touch display panel provided by the embodiments of the present application is introduced.

[0053] Figure 31 FIG. 1 is an exploded structural schematic diagram of a touch display panel provided by some embodiments of the present application, Figure 1 FIG. 2 is a structural schematic diagram of the opaque metal traces in the first packaging area of a display panel provided by some embodiments of the present application, Figure 2 FIG. 3 is another structural schematic diagram of the opaque metal traces in the first packaging area of a display panel provided by some embodiments of the present application.

[0054] Reference Figure 3 The embodiments of the present application provide a touch display panel, which includes a display area AA and a non-display area NA, and further includes a display panel 10 and a touch panel 20. The display panel 10 includes a first packaging area 11 in the non-display area NA, and the first packaging area 11 is provided with opaque metal traces 111 and gaps 112 outside the opaque metal traces 111.

[0055] In the embodiments of the present application, the first packaging area 11 of the display panel 10 can be a lower step region of the display panel 10, and the lower step region of the display panel 10 is provided with the opaque metal traces 111. The opaque metal traces 111 include at least one of a shift register signal line H, a power signal line K, or a fan-out line L.

[0056] Exemplarily, the opaque metal traces 111 in the first packaging area 11 can be one of the shift register signal line H, the power signal line K, or the fan-out line L, or two or more of the shift register signal line H, the power signal line K, or the fan-out line L.

[0057] When the opaque metal traces 111 in the first packaging area 11 include two or more of the shift register signal lines H, the power signal lines K, or the fan-out lines L, the two or more of the shift register signal lines H, the power signal lines K, or the fan-out lines L can be arranged adjacently or can be arranged overlappingly.

[0058] In some alternative embodiments, the opaque metal traces 111 in the first packaging area 11 can further include floating metal lines for improving the trace pattern structure in some areas of the display panel 10.

[0059] For a clearer description of the embodiments of the present application, the opaque metal traces 111 in the first packaging area 11 are taken as an example to include the shift register signal lines H, the power signal lines K, and the fan-out lines L. For the purpose of description, the first packaging area 11 is taken as an example to include three trace areas 30, and the three trace areas 30 in the first packaging area 11 are named as a first trace area 31, a second trace area 32, and a third trace area 33, respectively.

[0060] Continuing to refer to Figures 1 to 3 , the shift register signal lines H, the power signal lines K, and the fan-out lines L can be arranged adjacently, i.e., the projections of the shift register signal lines H, the power signal lines K, and the fan-out lines L on the display panel 10 do not overlap and are arranged adjacently along a direction perpendicular to the display panel 10. For the purpose of description, the first trace area 31 is provided with the shift register signal lines H, the second trace area 32 is provided with the power signal lines K, and the third trace area 33 is provided with the fan-out lines L.

[0061] Continuing to refer to Figure 2 , the shift register signal lines H, the power signal lines K, and the fan-out lines L can also be arranged overlappingly, i.e., the projections of two or more of the shift register signal lines H, the power signal lines K, and the fan-out lines L on the display panel 10 overlap. For the purpose of description, the first trace area 31 is provided with the shift register signal lines H, the second trace area 32 is provided with the power signal lines K and the shift register signal lines H, and the third trace area 33 is provided with the fan-out lines L.

[0062] The gaps 112 in the first packaging area 11 of the display panel 10, other than the opaque metal traces 111, can be understood as light-transmissive gaps between adjacent opaque metal traces 111. By Figure 3 and Figure 2It can be seen that the light transmittance of the first packaging area 11 of the display panel 10 is also complex due to the complex arrangement of the opaque metal traces 111 in the first packaging area 11 of the display panel 10.

[0063] The light transmittance refers to the transmittance of laser. It can be understood that the opaque metal traces 111 can shield and reflect the laser emitted by the laser source, that is, the laser cannot penetrate the opaque metal traces 111, and the gap 112 outside the opaque metal traces 111 can allow the laser to penetrate. In this way, the light transmittance can be understood as the area ratio between the gap 112 and the opaque metal traces 111. Specifically, along the extension direction of the plane where the display panel 10 is located, the first packaging area 11 of the display panel 10 has multiple different light transmittances, and the more different values of the light transmittance in the first packaging area 11, the higher the complexity of the light transmittance of the first packaging area 11.

[0064] For example, continuing to refer to Figure 3 and Figure 2 , along the first direction X, the light transmittance of the first trace area 31 is A, the light transmittance of the second trace area 32 is B, and the light transmittance of the third trace area 33 is C, A≠B≠C. In this way, the first packaging area 11 of the display panel 10 has at least three different light transmittances A, B, and C along the first direction X. It should be noted that the above light transmittance is only used to illustrate the technical solutions of the present application, but not to limit them.

[0065] In order to more clearly describe the technical solutions in the embodiments of the present application, the following are described with reference to the display panel 10 structure shown in Figure 3 .

[0066] Figure 2 For the first opaque metal pattern structure of the second packaging area of a touch panel matched with the display panel shown in Figure 4 , Figure 2 for the overlapping relationship structure after lamination, Figure 5 and Figure 2 laminated, Figure 4 for the laminated relationship structure after lamination, Figure 6 and Figure 2 laminated, Figure 4 for the first opaque metal pattern structure of the second packaging area of another touch panel matched with the display panel shown in Figure 7 , Figure 2 for the overlapping relationship structure after lamination, Figure 8 and Figure 2 laminated, Figure 7 for the laminated relationship structure after lamination, Figure 9 and Figure 2 laminated.

[0067] It should be noted that, in the embodiments of the present application, the above description continues to refer to Figure 7 The second packaging area 21 of the touch panel 20 can overlap one of the first, second and third wiring areas 31, 32 and 33. The above description continues to refer to Figures 4 to 6 The second packaging area 21 of the touch panel 20 can overlap two or more of the first, second and third wiring areas 31, 32 and 33.

[0068] The above description continues to refer to Figures 7 to 9 The touch panel 20 is stacked with the display panel 10, and the touch panel 20 includes the second packaging area 21 located in the non-display area NA and corresponding to the first packaging area 11. The second packaging area 21 includes the first metal layer 211, and the first metal layer 211 includes the first opaque metal pattern 211a.

[0069] In the embodiments of the present application, the first opaque metal pattern 211a can be a touch signal pad terminal of the touch panel 20. The first opaque metal pattern 211a can include opaque metal materials such as aluminum, platinum, palladium, silver, magnesium, gold, nickel, neodymium, iridium, chromium, titanium, tantalum, tungsten, copper or molybdenum. Optionally, a touch signal line is further connected to the side of the touch signal pad terminal close to the display area AA.

[0070] The overlapping relationship between the opaque metal wiring 111 in the first packaging area 11 and the first opaque metal pattern 211a in the second packaging area 21 will affect the complexity of the overall light transmittance. The effect of the complexity of the overall light transmittance on the packaging effect will be further described below.

[0071] Specifically, the touch panel 20 is stacked with the display panel 10 along a direction perpendicular to the display panel 10, so that the first packaging area 11 and the second packaging area 21 are also stacked along the direction perpendicular to the display panel 10. For ease of description, in the embodiments of the present application, the stacked structure formed after the first packaging area 11 and the second packaging area 21 are stacked is referred to as an overall packaging area, and the light transmittance of the overall packaging area is referred to as the overall light transmittance. If the first opaque metal pattern 211a located in the second packaging area 21 overlaps the part of the gap 112 other than the opaque metal wiring 111 located in the first packaging area 11, the first opaque metal pattern 211a will shield the part of the gap 112, thereby affecting the complexity of the overall light transmittance.

[0072] It should be noted that, in the packaging process of the touch display panel, the packaging material needs to be arranged in the corresponding area between the first packaging area 11 of the display panel 10 and the second packaging area 21 of the touch panel 20. The laser emitted by the laser source can be radiated onto the packaging material through the second packaging area 21. The laser radiation can melt the packaging material. Subsequently, the melted packaging material hardens to form a sealing layer, thereby completing the packaging work. Further, the part of the opaque metal trace 111 located in the first packaging area 11 of the display panel 10 can reflect the laser passing through the packaging material. The reflected laser is further reflected onto the packaging material to melt the packaging material. In this way, the overall light transmittance of the touch display panel can affect the efficiency of the laser irradiation onto the packaging material, thereby affecting the adjustment of the laser source energy.

[0073] In the packaging process of the touch display panel, the laser source energy needs to be adjusted for different overall light transmittances to make the laser energy radiated onto the packaging material meet the requirements. That is, one overall light transmittance value corresponds to one laser source energy value. The more complex the overall light transmittance is, the more times the corresponding laser source energy needs to be adjusted during the packaging process, resulting in a greater difficulty in adjusting the laser source energy, thereby resulting in poor packaging reliability and affecting product yield.

[0074] For example, in order to more clearly illustrate the technical solutions of the present application, the laser source energy is set as a, the overall light transmittance is set as b, and the adjustment coefficient is set as c. a, b, and c satisfy the relationship: a = b * c. When 0 < b < 1, the laser source energy a increases with the increase of the overall light transmittance b. When b = 0, the laser source energy a is a constant value d. When b = 1, the laser source energy a is a constant value e, and d < e. In this way, the size of the laser source energy needs to be adjusted according to the size of the overall light transmittance. It should be noted that the above relationship is only used to illustrate that the size of the overall light transmittance can affect the adjustment of the laser source energy, and does not constitute a limitation on the present application.

[0075] In this way, in the above scheme of the embodiment of the present application, by adjusting the first opaque metal pattern 211a located in the first packaging area 11 of the touch panel 20, the projection of the first opaque metal pattern 211a on the display panel 10 in the direction perpendicular to the display panel 10 does not overlap with the gap 112 between the opaque metal traces 111 located in the second packaging area 21 of the display panel 10. Therefore, after the touch panel 20 is superimposed on the display panel 10, the first opaque metal pattern 211a located in the first packaging area 11 of the touch panel 20 does not block the gap 112 between the opaque metal traces 111 located in the second packaging area 21 of the display panel 10, thereby preventing the introduction of the touch panel 20 from further increasing the complexity of the light transmittance, effectively improving the packaging reliability of the touch display panel, and improving the product yield.

[0076] Figures 4 to 9 for Figure 10 The diagram shows the structure of the opaque metal traces in the first trace area of ​​the display panel. Figure 2 To and Figure 11 The diagram shows a structural schematic of a first opaque metal pattern in the second encapsulation area of ​​a touch panel, matching the opaque metal traces. Figure 10 for Figure 12 and Figure 10 A schematic diagram of the overlapping structure after layering. Figure 11 for Figure 13 and Figure 10 A schematic diagram of the stacked structure;

[0077] Continue to refer to Figure 11 The following description uses the overlap of the second encapsulation area 21 and the first trace area 31 of the touch panel 20 as an example. In some embodiments, at least a portion of the first opaque metal pattern 211a is located between the opaque metal trace 111 and the display area AA in a direction parallel to the plane of the display panel 10.

[0078] Optionally, along a direction parallel to the plane of the display panel 10, the first opaque metal pattern 211a may be entirely located between the opaque metal trace 111 and the display area AA, or a portion of the first opaque metal pattern 211a may be located between the opaque metal trace 111 and the display area AA.

[0079] For example, such as Figures 10 to 13 As shown, along a direction parallel to the plane of the display panel 10, the first opaque metal pattern 211a is entirely located between the opaque metal traces 111 and the display area AA. In this way, the first opaque metal pattern 211a will not overlap with the gaps 112 between the opaque metal traces 111 in the second encapsulation area 21, ensuring that the introduction of the touch panel 20 does not further increase the complexity of light transmittance. This effectively improves the encapsulation reliability of the touch display panel and increases product yield. Simultaneously, this arrangement is simple in structure and low in cost.

[0080] Figures 10 to 13 for Figure 14 The diagram shows the structure of the opaque metal traces in the first trace area of ​​the display panel. Figure 2 To and Figure 15 The diagram shows a structural schematic of a first opaque metal pattern in the second encapsulation area of ​​a touch panel, matching the opaque metal traces. Figure 14 To and Figure 16 The diagram shows a structural schematic of a transparent conductive pattern that matches the first opaque metallic pattern. Figure 15 for Figure 17 , Figure 14 and Figure 15An overlapping relationship structure after layering, Figure 16 To Figure 18 , Figure 14 With Figure 15 An overlapping relationship structure after layering.

[0081] With reference to Figure 16 , taking the overlapping of the second packaging area 21 of the touch panel 20 and the first wiring area 31 as an example. In some embodiments, the first opaque metal pattern 211a includes a first pattern unit 2111, and a projection of the first pattern unit 2111 on the display panel 10 in a direction perpendicular to the display panel 10 falls at least partially within a projection of the opaque metal wiring 111 on the display panel 10. The second packaging area 21 further includes a transparent conductive layer 212, which is arranged in a layering manner with the first metal layer 211, and the transparent conductive layer 212 is provided with a transparent conductive pattern 212a, and the first pattern unit 2111 is electrically connected with the transparent conductive pattern 212a.

[0082] Exemplarily, as shown in Figures 14 to 18 , in a direction parallel to the plane where the display panel 10 is located, a part of the first opaque metal pattern 211a is located between the opaque metal wiring 111 and the display area AA, and another part of the first opaque metal pattern 211a falls within the projection of the opaque metal wiring 111 on the display panel 10 in a direction perpendicular to the display panel 10.

[0083] Optionally, the number of the first pattern unit 2111 can be one, two or more, and the specific number of the first pattern unit 2111 is not limited in the present application, and can be selected according to actual conditions.

[0084] In the embodiments of the present application, taking the number of the first pattern unit 2111 as an example. By setting the first opaque metal pattern 211a to include a plurality of first pattern units 2111, the structure of the opaque metal wiring 111 on the display panel 10 located in the second packaging area 21 can be designed more flexibly during the preparation of the first opaque metal pattern 211a, that is, the structure shape and the setting position of the first opaque metal pattern 211a can be flexibly adjusted according to the different structures of the actual opaque metal wiring 111, further reducing the risk of the first opaque metal pattern 211a blocking the gap 112 between the opaque metal wiring 111 on the display panel 10 located in the second packaging area 21, and further improving the packaging reliability of the touch display panel. At the same time, compared with the first opaque metal pattern 211a in a continuous structure, the above setting can also simplify the preparation difficulty of the first opaque metal pattern 211a, which is conducive to reducing the cost and further improving the product yield.

[0085] Optionally, in a direction perpendicular to the display panel 10, the projection shape of the first pattern unit 2111 on the display panel 10 can be a rectangle, a circle, a triangle, or a trapezoid, etc., and the present application does not limit the specific projection shape of the first pattern unit 2111 on the display panel 10, which can be selected according to actual conditions.

[0086] It should be noted that the first opaque metal pattern 211a includes a plurality of first pattern units 2111, and since the gaps 112 between the plurality of first pattern units 2111 and the opaque metal traces 111 do not overlap, the plurality of first pattern units 2111 are spaced apart and insulated from each other, and the plurality of first pattern units 2111 cannot transmit signals. Thus, in some optional embodiments, the second packaging area 21 further includes a transparent conductive layer 212, the transparent conductive layer 212 is stacked with the first metal layer 211, the transparent conductive layer 212 is provided with a transparent conductive pattern 212a, the first pattern unit 2111 is electrically connected with the transparent conductive pattern 212a, thereby enabling the plurality of first pattern units 2111 spaced apart from each other to be electrically connected with each other.

[0087] Optionally, the transparent conductive layer 212 can be made of a transparent conductive material, for example, the transparent conductive layer 212 can include, but is not limited to, transparent conductive oxides such as indium tin oxide, indium zinc oxide, zinc oxide, or indium tin zinc oxide, etc.

[0089] Continuing to refer to Figure 20 , taking the overlapping of the second packaging area 21 of the touch panel 20 and the second trace area 32 as an example for description. In some optional embodiments, the first opaque metal pattern 211a includes a plurality of first pattern units 2111, each first pattern unit 2111 in the plurality of first pattern units 2111 can be connected with a touch signal line, that is, each first pattern unit 2111 in the plurality of first pattern units 2111 can transmit signals, in which case, the transparent conductive layer 212 does not need to be provided.

[0090] It can be understood from the above embodiments that the first opaque metal pattern 211a in the second packaging area 21 of the touch panel 20 overlapping with the third wiring area 33 is the same technical idea as the setting mode of the first opaque metal pattern 211a in the second packaging area 21 of the touch panel 20 overlapping with the first wiring area 31 or the second wiring area 32. Therefore, the setting mode of the first opaque metal pattern 211a in the second packaging area 21 of the touch panel 20 overlapping with the third wiring area 33 will not be described here.

[0091] In some embodiments, in the direction perpendicular to the display panel 10, the projection of the first pattern unit 2111 on the display panel 10 falls within the projection of the transparent conductive pattern 212a on the display panel 10, which can make the first pattern unit 2111 fully contact the transparent conductive pattern 212a, on the one hand, to further improve the electrical connection performance between the plurality of first pattern units 2111, and on the other hand, to effectively improve the utilization efficiency of the transparent conductive pattern 212a, which is beneficial to cost saving.

[0092] Figures 19 to 22 A structure diagram of the first opaque metal pattern 211a of the second packaging area 21 of the touch panel 20 provided in some embodiments of the present application.

[0093] Continuing to refer to Figure 23 In some embodiments, the first pattern unit 2111 is provided with an opening 40.

[0094] It should be noted that in the packaging process of the touch display panel, the touch panel 20 is stacked with the display panel 10, the packaging material is arranged on the side of the touch panel 20 close to the display panel 10, and the laser is irradiated from the side of the touch panel 20 away from the display panel 10. Therefore, the first opaque metal pattern 211a in the second packaging area 21 of the touch panel 20 will block and reflect part of the laser, so that this part of the laser cannot irradiate the packaging material.

[0095] In the above technical solution, by opening the opening 40 on the first pattern unit 2111, the laser can irradiate more packaging material through the opening 40. Thus, under the condition of the same light transmittance, the laser energy can be adjusted by a certain order of magnitude, thereby effectively improving the utilization efficiency of the laser energy and saving the cost.

[0096] Alternatively, the shape of the opening 40 can be, but is not limited to, a circle, a rectangle, or a triangle, and the like. The specific shape of the opening 40 is not limited in the present application, and can be selected according to the actual situation.

[0097] Figure 23 For the same purpose as Figure 24A structural schematic view of a second opaque metal pattern of a second packaging area of a touch panel matching the first opaque metal pattern, Figure 15 As Figure 25 , Figure 14 , Figure 15 And Figure 16 A structural schematic view of an overlapping relationship after lamination, Figure 24 As Figure 26 , Figure 14 , Figure 15 And Figure 16 A structural schematic view of a lamination relationship after lamination.

[0098] With reference to Figure 24 In some embodiments, the touch panel 20 further comprises a second metal layer 213 disposed on the side of the first metal layer 211 close to the transparent conductive layer 212, and the second metal layer 213 is provided with a second opaque metal pattern 213a which does not overlap the gap 112, and the second opaque metal pattern 213a comprises second pattern units 2131 which are electrically connected to the first pattern units 2111 and the transparent conductive layer 212.

[0099] In the embodiments of the present application, the material of the second metal layer 213 can be the same as that of the first metal layer 211, for example, can be an opaque metal material such as aluminum, platinum, palladium, silver, magnesium, gold, nickel, neodymium, iridium, chromium, titanium, tantalum, tungsten, copper or molybdenum.

[0100] Optionally, in the direction perpendicular to the display panel 10, the projection shape of the second pattern units 2131 on the display panel 10 can be the same as or different from the projection shape of the first pattern units 2111 on the display panel 10.

[0101] In the above technical solution, by disposing the second metal layer 213 and electrically connecting the first metal layer 211 and the transparent conductive layer 212, i.e., connecting the second metal layer 213 in parallel between the first metal layer 211 and the transparent conductive layer 212, the impedance of the touch pad terminal on the touch panel 20 can be effectively reduced.

[0102] In some embodiments, in the direction perpendicular to the display panel 10, the projection of the second pattern units 2131 on the display panel 10 falls within the projection of the first pattern units 2111 on the display panel 10, which can make the second opaque metal pattern 213a fully contact the first opaque metal pattern 211a, on the one hand, to further reduce the impedance of the touch pad terminal on the touch panel 20, and on the other hand, to effectively improve the utilization efficiency of the second metal layer 213, which is conducive to cost saving.

[0103] In some embodiments, the first packaging area 11 includes at least two wiring areas 30, and the wiring areas 30 are provided with the opaque metal wires 111 and the gaps 112. The first metal layer 211 further includes a third opaque metal pattern 211b, and a projection of the third opaque metal pattern 211b on the display panel 10 in a direction perpendicular to the display panel 10 partially overlaps with the gaps 112 in the partial wiring areas 30, so as to reduce the difference between the light transmittances of the at least two wiring areas 30.

[0104] In the embodiments of the present application, the wiring areas 30 in the first packaging area 11 can be two, three, four or the like, and the present application does not limit the specific number of the wiring areas 30 in the first packaging area 11. The at least two wiring areas 30 in the first packaging area 11 can be arranged in sequence along the width direction of the display panel 10, or can be arranged in sequence along the length direction of the display panel 10, and the at least two wiring areas 30 in the first packaging area 11 can be arranged adjacently or can be arranged at intervals.

[0105] The first metal layer 211 further includes a third opaque metal pattern 211b, and the material of the third opaque metal pattern 211b can be the same as that of the first opaque metal pattern 211a, for example, can be an opaque metal material such as aluminum, platinum, palladium, silver, magnesium, gold, nickel, neodymium, iridium, chromium, titanium, tantalum, tungsten, copper or molybdenum. A projection of the third opaque metal pattern 211b on the display panel 10 in a direction perpendicular to the display panel 10 partially overlaps with the gaps 112 in the partial wiring areas 30, that is, the third opaque metal pattern 211b can block part of the gaps 112 in the partial wiring areas 30 in the direction perpendicular to the display panel 10, so as to change the light transmittance of the partial wiring areas 30, and further reduce the difference between the light transmittances of the at least two wiring areas 30 in the first packaging area 11, thereby further reducing the complexity of the light transmittance of the overall packaging area of the touch display panel, further improving the packaging reliability of the touch display panel, and further improving the product yield.

[0106] As described above, in order to more clearly describe the embodiments of the present application, the opaque metal wires 111 in the first packaging area 11 are taken as an example of the shift register signal line H, the power signal line K and the fan-out line L.

[0107] For the convenience of description, the first packaging area 11 is taken as an example of including three wiring areas 30, and the three wiring areas 30 in the first packaging area 11 are named as the first wiring area 31, the second wiring area 32 and the third wiring area 33 respectively. And, the structure of the display panel 10 shown in FIG. 2 is taken as an example for description. Figures 24 to 26

[0108] Continuing to refer to​Figure 2 For the sake of more clearly describing the embodiments of the present application, the transmittance of the first wiring area 31, the second wiring area 32 and the third wiring area 33 is set as an example, for example, the transmittance of the first wiring area 31 is 65%, the transmittance of the second wiring area 32 is 85%, and the transmittance of the third wiring area 33 is 40%.

[0109] Figure 2 A schematic diagram of the overlapping relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern after the display panel and the touch panel of the touch display panel provided by some embodiments of the present application are laminated, Figure 27 A schematic diagram of the overlapping relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern after the display panel and the touch panel of the touch display panel provided by some embodiments of the present application are laminated, Figure 28 A schematic diagram of the overlapping relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern after the display panel and the touch panel of the touch display panel provided by some embodiments of the present application are laminated.

[0110] Continuing to refer to Figure 27 Firstly, by adjusting the graphic design of the third opaque metal pattern 211b, the third opaque metal pattern 211b is overlapped with the gap 112 between the opaque metal wirings 111 of the first wiring area 31 along the direction perpendicular to the display panel 10, so that the third opaque metal pattern 211b shields the gap 112 between the opaque metal wirings 111 of the first wiring area 31 along the direction perpendicular to the display panel 10, for example, shielding 20% of the gap 112, so that after the touch panel 20 and the display panel 10 are overlapped, the overall transmittance of the touch display panel corresponding to the first wiring area 31 becomes 45%;

[0111] Further, by adjusting the graphic design of the third opaque metal pattern 211b, the third opaque metal pattern 211b is overlapped with the gap 112 between the opaque metal traces 111 of the second trace area 32 in the direction perpendicular to the display panel 10, so that the third opaque metal pattern 211b shields the gap 112 between the opaque metal traces 111 of the second trace area 32 in the direction perpendicular to the display panel 10, for example, shielding 30% of the gap 112, so that after the touch panel 20 is overlaid with the display panel 10, the overall light transmittance of the touch display panel corresponding to the second trace area 32 becomes. In this way, by setting the third opaque metal pattern 211b, after the touch panel 20 is overlaid with the display panel 10, the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 becomes 45%, 55% and 40% respectively, so it can be seen that the difference between the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 is reduced, so that the complexity of the laser source energy adjustment in the packaging process of the touch display panel is reduced, which is more conducive to improving the packaging reliability of the touch display panel and improving the product yield. Of course, under the condition that the process requirement can be reached, the third opaque metal pattern 211b can also be set so that the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 is the same after the touch panel 20 is overlaid with the display panel 10, so as to further improve the packaging reliability of the touch display panel.

[0112] It should be noted that the above exemplary embodiments are only used to illustrate the technical solutions of the present application, and not to limit them, and the number of trace areas 30 in the first packaging area 11 and the light transmittance of the trace areas 30 can be other specific values according to the actual application environment, which is not limited in the present application.

[0113] In some embodiments, at least part of the third opaque metal pattern 211b is located in the same trace area 30 as the first opaque metal pattern 211a.

[0114] It should be noted that in the embodiments of the present application, the first opaque metal pattern 211a is connected with a touch signal line at one end close to the display area AA, so that the first opaque metal pattern 211a is located in at least one of the above-mentioned trace areas 30 according to the arrangement of the touch signal line of different devices. For example, the first packaging area 11 includes the first trace area 31, the second trace area 32 and the third trace area 33, and the first opaque metal pattern 211a can be located in one of the first trace area 31, the second trace area 32 and the third trace area 33, or can be located in two or more of the first trace area 31, the second trace area 32 and the third trace area 33.

[0115] Exemplarily, the third opaque metal pattern 211b can be electrically connected with the first opaque metal pattern 211a; the third opaque metal pattern 211b can also be not electrically connected with the first opaque metal pattern 211a, i.e. the third opaque metal pattern 211b and the first opaque metal pattern 211a are insulated from each other.

[0116] Exemplarily, continuing to refer to Figures 27 to 28 , the first opaque metal pattern 211a is arranged in the first wiring area 31, and the third opaque metal pattern 211b is arranged in the first wiring area 31 and the second wiring area 32, so that in the first wiring area 31, the third opaque metal pattern 211b is electrically connected with the first opaque metal pattern 211a, and in the second wiring area 32, the third opaque metal pattern 211b is insulated from the first opaque metal pattern 211a in the first wiring area 31.

[0117] In the above technical solution, when at least part of the third opaque metal pattern 211b is located in the same wiring area 30 as the first opaque metal pattern 211a, the third opaque metal pattern 211b in the wiring area 30 is electrically connected with the first opaque metal pattern 211a, so that in the manufacturing process of the first opaque metal pattern 211a and the third opaque metal pattern 211b in the wiring area 30, the first opaque metal pattern 211a and the third opaque metal pattern 211b can be manufactured together in the same process, thereby reducing the overall manufacturing process and improving the manufacturing efficiency and reducing the cost.

[0118] Figures 27 to 28 Another schematic diagram of the overlapping relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern of the display panel and the touch panel of the touch display panel provided by some embodiments of the present application after the display panel and the touch panel are laminated, Figure 29 as shown in the schematic diagram of the laminated relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern of the display panel and the touch panel of the touch display panel. Figure 30 as shown in the schematic diagram of the laminated relationship structure of the opaque metal wiring, the first opaque metal pattern and the third opaque metal pattern of the display panel and the touch panel of the touch display panel.

[0119] In some optional embodiments, the first opaque metal pattern 211a and the third opaque metal pattern 211b are located in different wiring areas 30, and the third opaque metal pattern 211b is arranged to be insulated from the first opaque metal pattern 211a. Exemplarily, continuing to refer to Figure 29The first opaque metal pattern 211a is arranged in the third wiring area 33, and the third opaque metal pattern 211b is arranged in the first wiring area 31 and the second wiring area 32, so that the first opaque metal pattern 211a and the third opaque metal pattern 211b are located in different wiring areas 30 and are insulated from each other.

[0120] In some embodiments, in the first packaging area 11, an absolute value of a difference between the light transmittances of any two wiring areas 30 is less than or equal to 10%.

[0121] As described above, for ease of description, the first packaging area 11 is also taken as an example including the first wiring area 31, the second wiring area 32, and the third wiring area 33, and the light transmittance of the first wiring area 31 is 65%, the light transmittance of the second wiring area 32 is 85%, and the light transmittance of the third wiring area 33 is 40%.

[0122] For example, by using the above technical means, the third opaque metal pattern 211b is arranged, so that after the touch panel 20 is stacked with the display panel 10, the overall light transmittances of the touch display panel corresponding to the first wiring area 31, the second wiring area 32, and the third wiring area 33 are changed to 45%, 50%, and 40%, respectively. It should be noted that when the overall light transmittances of the touch display panel corresponding to the first wiring area 31, the second wiring area 32, and the third wiring area 33 are relatively close, the influence of the penetration of the laser can be ignored, so that the same order of magnitude of laser energy is used for packaging, thereby further reducing the difficulty of adjusting the energy of the laser source in the packaging process of the touch display panel, and more conducive to improving the packaging reliability and product yield of the touch display panel. Of course, the third opaque metal pattern 211b can also be arranged so that after the touch panel 20 is stacked with the display panel 10, the overall light transmittances of the touch display panel corresponding to the first wiring area 31, the second wiring area 32, and the third wiring area 33 are changed to 45%, 47%, and 40%, respectively. The above example embodiments are only used to illustrate the technical solutions of the present application, and not to limit them. The number of the wiring areas 30 in the first packaging area 11 and the light transmittances of the wiring areas 30 can be other specific values according to actual application environment, which are not limited in the present application.

[0123] In some embodiments, in the first packaging area 11, the light transmittances of at least two wiring areas 30 gradually increase along a first direction X, and the first direction X is a direction in which the at least two wiring areas 30 are arranged, or the light transmittances of the at least two wiring areas 30 gradually decrease along the first direction X.

[0124] As above, for the convenience of description, it is also taken as an example that the first packaging area 11 includes the first trace area 31, the second trace area 32 and the third trace area 33, and the light transmittance of the first trace area 31 is 65%, the light transmittance of the second trace area 32 is 85%, and the light transmittance of the third trace area 33 is 40% for description.

[0125] Exemplarily, in some exemplary embodiments, by setting the third opaque metal pattern 211b, so that after the touch panel 20 is superimposed with the display panel 10, the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 is changed to 65%, 55% and 40% respectively. It should be noted that when the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 gradually increases or gradually decreases along the first direction X, the laser energy can also be adjusted along the gradually increasing trend or the gradually decreasing trend along the first direction X during the packaging of the touch display panel, so that the difficulty of adjusting the energy of the laser source can be simplified, and the packaging reliability and product yield of the touch display panel can be improved. Of course, the third opaque metal pattern 211b can also be set so that after the touch panel 20 is superimposed with the display panel 10, the overall light transmittance of the touch display panel corresponding to the first trace area 31, the second trace area 32 and the third trace area 33 is changed to 60%, 50% and 40% respectively. The above exemplary embodiments are only used to illustrate the technical solutions of the present application, but not to limit them, and the number of trace areas 30 in the first packaging area 11 and the light transmittance of the trace areas 30 can be other specific values according to actual application environment, which are not limited by the present application.
