[0033] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0034] In the related art, the touch electrodes of the touch panel adopt a metal grid design. In order to prevent short circuit, a break design is usually adopted between the touch electrodes of different signals, that is, there is a gap between two adjacent touch electrodes. However, under strong light, the reflection of the wiring under the gap is relatively serious, resulting in the problem of bright lines in the gap, which seriously affects the visual experience of customers.

[0035] In view of this, the embodiments of the present application provide a touch panel and a display device, wherein a first shielding portion is provided so that at least a portion of the orthographic projection of the first shielding portion on the substrate is located between the orthographic projection of the first electrode portion on the substrate and the orthographic projection of the second electrode portion on the substrate, so that the first shielding portion can shield at least a portion of the gap between the first electrode and the second electrode, thereby reducing the amount of reflected light emitted from the gap, improving the problem of bright lines in the gap, and improving the user's visual experience. In addition, by making the distance between the first shielding portion and the substrate unequal to the distance between the first electrode portion and the substrate, it is equivalent to staggering the first electrode portion and the first shielding portion in the thickness direction of the touch panel, thereby reducing the risk of short circuit between the first shielding portion and the second electrode portion.

[0036] First, refer to Figure 1-Figure 12 As shown, an embodiment of the present application provides a touch panel 10 , which includes a substrate 11 , a touch structure layer 12 and a first shielding portion 13 .

[0037] Among them, the touch structure layer 12 is arranged on one side of the substrate 11. The touch structure layer 12 includes a first electrode portion 121 and a second electrode portion 122, and the first electrode portion 121 and the second electrode portion 122 are arranged at intervals along the first direction X. The first direction X is perpendicular to the thickness direction of the substrate 11. The first shielding portion 13 is connected to the first electrode portion 121, and the distance between the first shielding portion 13 and the substrate 11 is not equal to the distance between the first electrode portion 121 and the substrate 11. For example: the distance between the first shielding portion 13 and the substrate 11 is greater than the distance between the first electrode portion 121 and the substrate 11, or the distance between the first shielding portion 13 and the substrate 11 is less than the distance between the first electrode portion 121 and the substrate 11.

[0038] Further, at least a portion of the orthographic projection of the first shielding portion 13 on the substrate 11 is located between the orthographic projection of the first electrode portion 121 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11. In other words, in the thickness direction of the touch panel 10, a gap S is formed between the first electrode portion 121 and the second electrode portion 122, and the first shielding portion 13 at least shields a portion of the gap S.

[0039] It should be noted that the touch panel 10 in the embodiment of the present application can be an external type or an integrated type. If the touch panel 10 is an external type, the touch panel 10 can be externally mounted on a display screen to form a touch display panel. In this case, the substrate 11 is a base material layer for carrying the touch structure layer 12 and the first shielding portion 13. If the touch panel 10 is an integrated type, the touch panel 10 can be integrated in a display screen to form a touch display panel. In this case, the substrate 11 can be a film layer in the display screen, such as an encapsulation layer.

[0040] The touch panel 10 provided in the embodiment of the present application is provided with a first shielding portion 13 so that at least a portion of the orthographic projection of the first shielding portion 13 on the substrate 11 is located between the orthographic projection of the first electrode portion 121 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11. In this way, the first shielding portion 13 can shield at least a portion of the gap S between the first electrode and the second electrode. In this way, the amount of reflected light emitted from the gap S is reduced, the problem of bright lines in the gap is improved, and the user's visual experience is enhanced.

[0041] In addition, by making the distance between the first shielding portion 13 and the substrate 11 unequal to the distance between the first electrode portion 121 and the substrate 11, that is, the heights of the first shielding portion 13 and the first electrode portion 121 are inconsistent. In this way, the first electrode portion 121 and the first shielding portion 13 are staggered in the thickness direction of the touch panel 10, which not only fully utilizes the space in the thickness direction of the touch panel 10, but also avoids the short circuit problem caused by the first shielding portion 13 easily contacting the second electrode portion 122 when the first shielding portion 13 and the first electrode portion 121 are at the same height.

[0042] In one embodiment, the first shielding portion 13 is disposed in the same layer as the first electrode portion 121. In this way, the first shielding portion 13 and the first electrode portion 121 can be manufactured simultaneously in the same process, thereby reducing the manufacturing cost.

[0043] It is understandable that the first shielding portion 13 and the first electrode portion 121 may also be manufactured in different processes, and this embodiment of the present application does not specifically limit this.

[0044] In one embodiment, the first shielding portion 13 is made of the same material as the first electrode portion 121. In this way, the reflectivity of the first shielding portion 13 and the first electrode portion 121 can be the same or close, so that the reflective effects of the first shielding portion 13 and the first electrode portion 121 are consistent, which is conducive to improving the user's visual experience.

[0045] In one embodiment, if Figure 2 As shown, the first shielding portion 13 is located on a side of the first electrode portion 121 close to the substrate 11, and at this time, the distance between the first shielding portion 13 and the substrate 11 is smaller than the distance between the first electrode portion 121 and the substrate 11. The touch panel 10 further includes a first insulating layer 14, the first insulating layer 14 is located between the first electrode portion 121 and the substrate 11, and the first insulating layer 14 is located between the second electrode portion 122 and the substrate 11; the first insulating layer 14 includes a first receiving groove 141, and the first shielding portion 13 is located in the first receiving groove 141.

[0046] By providing the first receiving groove 141 in the first insulating layer 14, it is equivalent to providing a receiving space for the first shielding portion 13 in the first insulating layer 14. It avoids the first shielding portion 13 interfering with other components and causing adverse effects on the arrangement of other components. By providing the first shielding portion 13 on the side of the first electrode portion 121 close to the substrate 11, it is convenient to simultaneously manufacture the first electrode portion 121 and the first shielding portion 13 in the same process. In one example, the first insulating layer 14 is firstly made on the substrate 11, and then the first receiving groove 141 is etched in the first insulating layer 14, and then the first electrode material is deposited and patterned to form the first electrode portion 121 and the first shielding portion 13.

[0047] It should be emphasized that the first shielding portion 13 may also be disposed on the side of the first electrode portion 121 away from the substrate 11 , and the embodiment of the present application does not specifically limit the location of the first shielding portion 13 .

[0048] In one embodiment, if Figure 2 As shown, the angle between the end surface of the first shielding portion 13 close to the first electrode portion 121 along the first direction X and the plane where the substrate 11 is located is θ 1 ,θ 1 Here, the plane where the substrate 11 is located is Figure 2 In the horizontal plane in FIG. 1 , the end surface of the first blocking portion 13 close to one end of the first electrode portion 121 along the first direction X is the end surface on the left side of the first blocking portion 13 in the figure.

[0049] In this way, on the one hand, the angle between the lower surface of the first electrode portion 121 and the left end surface of the first shielding portion 13 can be made non-right angle, and the angle between the lower surface of the first shielding portion 13 and the left end surface of the first shielding portion 13 can be made non-right angle, thereby reducing the right-angle tips in the touch panel 10 and avoiding the occurrence of tip discharge; on the other hand, this structure is easier to form in the process, reducing the difficulty of production.

[0050] In one embodiment, if Figure 2 As shown, the angle between the end surface of the first shielding portion 13 away from the first electrode portion 121 along the first direction X and the plane where the substrate 11 is located is θ 2 ,θ 2 Here, the plane where the substrate 11 is located is Figure 2 In the horizontal plane in FIG. 1 , the end surface of the first shielding portion 13 away from the first electrode portion 121 along the first direction X is the end surface on the right side of the first shielding portion 13 in the figure.

[0051] In this way, on the one hand, the angle between the upper surface of the first shielding portion 13 and the right side end face of the first shielding portion 13 can be made non-right angle, and the angle between the lower surface of the first shielding portion 13 and the right side end face of the first shielding portion 13 can be made non-right angle, thereby reducing the right-angle tip in the touch panel 10 and avoiding the tip discharge phenomenon; on the other hand, during the manufacturing process, the first insulating layer 14 is firstly manufactured on the substrate 11, and then the first receiving groove 141 is etched in the first insulating layer 14, and then the first electrode material is deposited and patterned to form the first electrode portion 121 and the first shielding portion 13.

[0052] In one embodiment, if Figure 5 As shown, the angle between the end surface of the first shielding portion 13 away from the first electrode portion 121 along the first direction X and the plane where the substrate 11 is located is θ 2 ,θ 2 Here, the plane where the substrate 11 is located is Figure 5 In the horizontal plane in FIG. 1 , the end surface of the first shielding portion 13 away from the first electrode portion 121 along the first direction X is the end surface on the right side of the first shielding portion 13 in the figure.

[0053] In this way, on the one hand, the angle between the upper surface of the first shielding portion 13 and the right side end surface of the first shielding portion 13 can be non-right angle, and the angle between the lower surface of the first shielding portion 13 and the right side end surface of the first shielding portion 13 can be non-right angle, thereby reducing the right-angle tip in the touch panel 10 and avoiding the tip discharge phenomenon; on the other hand, during the manufacturing process, firstly, a substrate 11 is manufactured Figure 5 The first insulating layer 14 on the left side is then deposited with a first electrode material and patterned to form a first electrode portion 121 and a first shielding portion 13. Then, a first electrode portion 121 is formed on the substrate 11. Figure 5 The first insulating layer 14 on the right side of the middle. In this way, it is equivalent to manufacturing the first insulating layer 14 through a two-step process.

[0054] In one embodiment, if Figure 2 As shown, the distance between the first electrode portion 121 and the substrate 11 is equal to the distance between the second electrode portion 122 and the substrate 11. That is, the first electrode portion 121 and the second electrode portion 122 are located at the same height. It can be understood that in this case, the first electrode portion 121 and the second electrode portion 122 can be arranged in the same layer, that is, they are made simultaneously in the same process.

[0055] Furthermore, the orthographic projection of the first shielding portion 13 on the substrate 11 is spaced from the orthographic projection of the second electrode portion 122 on the substrate 11. Specifically, Figure 2As shown, the distance between the first shielding portion 13 and the second electrode portion 122 is b, and the distance between the first electrode portion 121 and the second electrode portion 122 is a. In this way, the first shielding portion 13 can shield most of the gap S without contacting the second electrode portion 122, thereby avoiding the short circuit problem.

[0056] In one embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the distance between the first electrode portion 121 and the substrate 11 is not equal to the distance between the second electrode portion 122 and the substrate 11. That is, the first electrode portion 121 and the second electrode portion 122 are located at different heights. In other words, the first electrode portion 121 and the second electrode portion 122 are arranged in different layers.

[0057] Furthermore, the orthographic projection of the first shielding portion 13 on the substrate 11 covers a region between the orthographic projection of the first electrode portion 121 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11 .

[0058] In this way, the gap S between the first electrode portion 121 and the second electrode portion 122 can be completely shielded by the first shielding portion 13 , thereby maximally improving the problem of severe reflection at the gap S.

[0059] In one example, if Figure 3 and Figure 6 As shown, the orthographic projection of the first shielding portion 13 on the substrate 11 is connected to the orthographic projection of the second electrode portion 122 on the substrate 11, that is, the orthographic projection of the first shielding portion 13 on the substrate 11 does not overlap with the orthographic projection of the second electrode portion 122 on the substrate 11. In this way, the first shielding portion 13 can be fully utilized without causing waste, thereby reducing material costs.

[0060] In another example, Figure 4 and Figure 5 As shown, the orthographic projection of the first shielding portion 13 on the substrate 11 overlaps with the orthographic projection of the second electrode portion 122 on the substrate 11, that is, part of the first shielding portion 13 is located directly below the second electrode. In this way, when manufacturing the second electrode portion 122, even if there are some process errors, it will not affect the shielding of the gap S by the first shielding portion 13. Therefore, this structure has a lower requirement for process accuracy, which is conducive to reducing the process difficulty.

[0061] In one embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the touch panel 10 further includes a second insulating layer 15. The second insulating layer 15 is located on the side of the first electrode portion 121 and the first shielding portion 13 away from the substrate 11, and the second insulating layer 15 is located on the side of the second electrode portion 122 close to the substrate 11; that is, the second insulating layer 15 is located between the film layer where the first electrode portion 121 is located and the film layer where the second electrode portion 122 is located. In this way, a short circuit between the first electrode portion 121 and the second electrode portion 122 can be prevented.

[0062] In one embodiment, if Figure 7 As shown, the touch panel 10 further includes a second shielding portion 16, the second shielding portion 16 is connected to the second electrode portion 122, and the distance between the second shielding portion 16 and the substrate 11 is not equal to the distance between the second electrode portion 122 and the substrate 11. For example, the distance between the second shielding portion 16 and the substrate 11 is greater than the distance between the second electrode portion 122 and the substrate 11, or the distance between the second shielding portion 16 and the substrate 11 is less than the distance between the second electrode portion 122 and the substrate 11.

[0063] Among them, at least part of the orthographic projection of the second shielding portion 16 on the substrate 11 is located between the orthographic projection of the first electrode portion 121 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11. In other words, in the thickness direction of the touch panel 10, a gap S is formed between the first electrode portion 121 and the second electrode portion 122, and the second shielding portion 16 at least shields a part of the gap S.

[0064] By providing the second shielding portion 16, the gap S can be further shielded, the amount of reflected light emitted from the gap S is further reduced, the problem of bright lines in the gap is improved, and the user's visual experience is improved. It can also be understood that by providing the second shielding portion 16, on the one hand, the size of the first shielding portion 13 in the first direction X can be reduced; on the other hand, double-layer shielding is more conducive to solving the problem of poor shielding effect caused by process errors.

[0065] In one embodiment, the second shielding portion 16 is disposed on a side of the second electrode portion 122 away from the substrate 11. The touch panel 10 further includes a third insulating layer 17, which is located on a side of the first electrode portion 121 and the second electrode portion 122 away from the substrate 11; the third insulating layer 17 includes a second receiving groove 171, and the second shielding portion 16 is disposed in the second receiving groove 171.

[0066] By providing the second receiving groove 171 in the third insulating layer 17, it is equivalent to providing a receiving space for the second shielding portion 16 in the third insulating layer 17. This avoids the second shielding portion 16 interfering with other components and causing adverse effects on the arrangement of other components. By providing the second shielding portion 16 on the side of the second electrode portion 122 away from the substrate 11, it is possible to prevent the second shielding portion 16 from contacting the first electrode portion 121 and causing a short circuit. It is understandable that during the manufacturing process, the second receiving groove 171 is first etched in the third insulating layer 17, and then the second shielding material is deposited in the second receiving groove 171 to form the second shielding portion 16.

[0067] It is understandable that the second shielding portion 16 may also be disposed on a side of the second electrode portion 122 close to the substrate 11 , and the embodiment of the present application does not impose any specific limitation on the location of the second shielding portion 16 .

[0068] In one embodiment, the first shielding portion 13, the first electrode portion 121, the second shielding portion 16, and the second electrode portion 122 are made of the same material. In this way, the reflectivity of the first shielding portion 13, the first electrode portion 121, the second shielding portion 16, and the second electrode portion 122 can be made the same or close, so that the first shielding portion 13, the first electrode portion 121, the second shielding portion 16, and the second electrode portion 122 have the same reflective effect, which is conducive to improving the user's visual experience.

[0069] In one embodiment, if Figure 7 As shown, the angle between the end surface of the second shielding portion 16 close to the second electrode portion 122 along the first direction X and the plane where the substrate 11 is located is γ 2 , γ 2 The angle between the end surface of the second shielding portion 16 away from the second electrode portion 122 along the first direction X and the plane where the substrate 11 is located is γ 1 , γ 1 Here, the plane where the substrate 11 is located is Figure 7 The end surface of the second shielding portion 16 close to the second electrode portion 122 along the first direction X is the end surface on the right side of the second shielding portion 16 in the figure, and the end surface of the second shielding portion 16 away from the second electrode portion 122 along the first direction X is the end surface on the left side of the second shielding portion 16 in the figure.

[0070] In this way, on the one hand, the angle between the upper surface of the second electrode portion 122 and the right side end face of the second shielding portion 16 can be non-right angle, the angle between the upper surface of the second shielding portion 16 and the right side end face of the second shielding portion 16 can be non-right angle, the angle between the lower surface of the second shielding portion 16 and the right side end face of the second shielding portion 16 can be non-right angle, the angle between the upper surface of the second shielding portion 16 and the left side end face of the second shielding portion 16 can be non-right angle, and the angle between the lower surface of the second shielding portion 16 and the left side end face of the second shielding portion 16 can be non-right angle, thereby reducing the right-angle tips in the touch panel 10 and avoiding the occurrence of tip discharge; on the other hand, this structure is relatively easy to form in the process, reducing the difficulty of manufacturing.

[0071] In one embodiment, the orthographic projection of the first shielding portion 13 on the substrate 11 overlaps or connects with the orthographic projection of the second shielding portion 16 on the substrate 11. In this way, the first shielding portion 13 and the second shielding portion 16 can completely shield the gap S between the first electrode portion 121 and the second electrode portion 122, thereby maximally improving the problem of severe reflection at the gap S.

[0072] In one embodiment, if Figure 8 , Fig. 9 and Fig.10 As shown, the touch panel 10 further includes an optical film layer 18, which is located on a side of the first electrode portion 121 and the second electrode portion 122 away from the substrate 11. A gap S is provided between the first electrode portion 121 and the second electrode portion 122, and a side of the optical film layer 18 away from the substrate 11 includes a groove 181; along the thickness direction of the substrate 11, the groove 181 and the gap S overlap.

[0073] Thus, by providing an optical film layer 18 and providing a groove 181 overlapping with the gap S on the optical film layer 18, Fig. 9 As shown, when the reflected light is emitted from the gap S, it passes through the groove 181. The groove 181 can change the emission path of the reflected light, that is, further reduce the width of the optical path, weaken the width of the bright line under the strong light, and even make it invisible to the naked eye, thereby fundamentally improving the customer's visual experience.

[0074] It should be noted that, in this embodiment, there is a gap between the orthographic projection of the first shielding portion 13 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11 , and the reflected light is emitted from between the first shielding portion 13 and the second electrode portion 122 and then passes through the groove 181 .

[0075] In one embodiment, if Figure 8As shown, the groove 181 has a first side wall 181a and a second side wall 181b; along the first direction X, the first side wall 181a and the second side wall 181b are arranged opposite to each other, and the first side wall 181a is located on the side of the second side wall 181b close to the first electrode portion 121. The plane where the first side wall 181a is located is arranged at an angle with the plane where the substrate 11 is located, and the plane where the second side wall 181b is located is arranged at an angle with the plane where the substrate 11 is located. Specifically, the angle between the plane where the first side wall 181a is located and the plane where the substrate 11 is located is α 1 , α 1 The angle between the plane where the second side wall 181b is located and the plane where the substrate 11 is located is α 2 , α 2 It is an acute angle.

[0076] The above arrangement can more effectively change the emission path of the reflected light, thereby improving the reflection phenomenon at the gap S.

[0077] In one embodiment, the angle α between the plane where the first side wall 181a is located and the plane where the substrate 11 is located is 1 , satisfying the relationship: 30°≤α 1 <90°. For example, α 1 It can be 30°, 50°, 60°, 70°, 80°, 89°, etc. 1 Less than 30°, the effect on the change of the reflection path is relatively weak. 1 If the angle is greater than 90°, it is equivalent to not providing the groove 181. Therefore, the above arrangement can more effectively change the emission path of the reflected light, thereby improving the reflection phenomenon at the gap S.

[0078] In one embodiment, the angle α between the plane where the second side wall 181b is located and the plane where the substrate 11 is located is 2 , satisfying the relationship: 30°≤α 2 <90°. For example, α 2 It can be 30°, 50°, 60°, 70°, 80°, 89°, etc. 2 Less than 30°, the effect on the change of the reflection path is relatively weak. 2 If the angle is greater than 90°, it is equivalent to not providing the groove 181. Therefore, the above arrangement can more effectively change the emission path of the reflected light, thereby improving the reflection phenomenon at the gap S.

[0079] In one example, if Figure 8 As shown in FIG. 1 , along the direction perpendicular to the paper surface, the cross-sectional shape of the groove 181 is a triangle. In another example, as shown in FIG. Fig. 9As shown, along the direction perpendicular to the paper surface, the cross-sectional shape of the groove 181 is a trapezoid. It is understandable that the cross-sectional shape of the groove 181 can also be other shapes, and the embodiment of the present application does not specifically limit this.

[0080] In one embodiment, if Figure 8 and Fig. 9 As shown, the groove 181 penetrates part of the structure of the optical film layer 18 along the thickness direction of the substrate 11. In this way, during the process of etching the groove 181, damage to the film layer below the optical film layer 18 (such as the first electrode portion 121 and the first shielding portion 13) can be avoided.

[0081] It is understandable that if Fig.10 As shown, along the thickness direction of the substrate 11 , the groove 181 may also penetrate the optical film layer 18 .

[0082] In one embodiment, if Fig.11 As shown, the touch structure layer 12 includes touch driving electrodes 12a, touch sensing electrodes 12b and dummy electrodes 12c.

[0083] In one embodiment, one of the first electrode portion 121 and the second electrode portion 122 is a touch driving electrode 12 a , and the other is a touch sensing electrode 12 b .

[0084] In one embodiment, one of the first electrode portion 121 and the second electrode portion 122 is a touch driving electrode 12 a , and the other is a dummy electrode 12 c .

[0085] In one embodiment, one of the first electrode portion 121 and the second electrode portion 122 is a touch sensing electrode 12 b , and the other is a dummy electrode 12 c .

[0086] It should be noted that, in the same touch panel 10, the first blocking portion 13 and / or the second blocking portion 16 may be provided at the gap S between the touch driving electrode 12a and the touch sensing electrode 12b, the first blocking portion 13 and / or the second blocking portion 16 may be provided at the gap S between the touch driving electrode 12a and the dummy electrode 12c, and the first blocking portion 13 and / or the second blocking portion 16 may be provided at the gap S between the touch sensing electrode 12b and the dummy electrode 12c.

[0087] In one embodiment, in combination Figure 2 As shown, the size of the first shielding portion 13 along the second direction is not less than the size of the first electrode portion 121 along the second direction. The second direction is perpendicular to the first direction X and the thickness direction of the substrate 11. Figure 2 , the second direction is the direction perpendicular to the paper surface.

[0088] In this way, the width of the first shielding portion 13 is equal to or greater than the width of the first electrode portion 121 . In this way, the shielding area of ​​the first shielding portion 13 can be larger, which can improve the problem of the bright line between gaps to the greatest extent.

[0089] In one example, the size of the first blocking portion 13 along the second direction is greater than the size of the first electrode portion 121 along the second direction. In another example, the size of the first blocking portion 13 along the second direction is equal to the size of the first electrode portion 121 along the second direction.

[0090] In one embodiment, a dimension of the first shielding portion 13 along the second direction is not less than a dimension of the second electrode portion 122 along the second direction.

[0091] In this way, the width of the first shielding portion 13 is equal to or greater than the width of the second electrode portion 122 . In this way, the shielding area of ​​the first shielding portion 13 can be larger, which can improve the problem of the bright line between gaps to the greatest extent.

[0092] In one example, the size of the first blocking portion 13 along the second direction is greater than the size of the second electrode portion 122 along the second direction. In another example, the size of the first blocking portion 13 along the second direction is equal to the size of the second electrode portion 122 along the second direction.

[0093] In one embodiment, in combination Figure 7 As shown, the size of the second shielding portion 16 along the second direction is not less than the size of the second electrode portion 122 along the second direction. The second direction is perpendicular to the first direction X and the thickness direction of the substrate 11. Figure 7 , the second direction is the direction perpendicular to the paper surface.

[0094] In this way, the width of the second shielding portion 16 is equal to or greater than the width of the second electrode portion 122 . In this way, the shielding area of ​​the second shielding portion 16 can be larger, thereby improving the problem of the bright line between gaps to the greatest extent.

[0095] In one example, the size of the second blocking portion 16 along the second direction is greater than the size of the second electrode portion 122 along the second direction. In another example, the size of the second blocking portion 16 along the second direction is equal to the size of the second electrode portion 122 along the second direction.

[0096] In one embodiment, a dimension of the second shielding portion 16 along the second direction is not less than a dimension of the first electrode portion 121 along the second direction.

[0097] In this way, the width of the second shielding portion 16 is equal to or greater than the width of the first electrode portion 121 . In this way, the shielding area of ​​the second shielding portion 16 can be larger, which can improve the problem of the bright line between gaps to the greatest extent.

[0098] In one example, the size of the second blocking portion 16 along the second direction is greater than the size of the first electrode portion 121 along the second direction. In another example, the size of the second blocking portion 16 along the second direction is equal to the size of the first electrode portion 121 along the second direction.

[0099] In one embodiment, if Fig.12 As shown, the touch panel 10 further includes an anode metal layer 110, and the anode metal layer 110 is disposed between the touch structure layer 12 and the substrate 11. The area between the orthographic projection of the first electrode portion 121 on the substrate 11 and the orthographic projection of the second electrode portion 122 on the substrate 11 is a spacing area, and at least part of the spacing area is located outside the orthographic projection of the anode metal layer 110 on the substrate 11.

[0100] The inventors have found through research that the reflectivity of the anode metal layer 110 is higher than that of the metal in the touch structure layer 12. Under strong light, the light reflected by the anode metal layer 110 is emitted from the gap S, resulting in the problem of bright lines in the gap. The above configuration is equivalent to making part of the metal of the anode metal layer 110 not overlap with the gap S, which is conducive to improving the problem of bright lines in the gap caused by the anode metal layer 110.

[0101] It is understandable that if Fig.12 As shown, the touch panel 10 may further include a driving structure layer 19, a light emitting layer 111 and a cathode metal layer 112, wherein the anode metal layer 110 is disposed on the driving structure layer 19, the light emitting layer 111 is disposed on a side of the anode metal layer 110 away from the driving structure layer 19, the cathode metal layer 112 is disposed on a side of the light emitting layer 111 away from the driving structure layer 19, and the touch structure layer 12 is disposed on a side of the cathode metal layer 112 away from the driving structure layer 19. It is understood that an encapsulation layer (not shown) may be disposed between the touch structure layer 12 and the cathode metal layer 112.

[0102] Second, as Fig.13 As shown, an embodiment of the present application provides a display device 1, comprising the display panel in any embodiment of the first aspect.

[0103] The display device 1 can be a laptop computer, a mobile phone, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camcorder, a game console, a watch, a clock, a calculator, a television monitor, a flat-panel display, a computer monitor, a car display (e.g., an odometer display, etc.), a navigator, a cockpit controller and / or display, a display of a camera view (e.g., a display of a rearview camera in a vehicle), an electronic photo, an electronic billboard or sign, a projector, etc.

[0104] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
