[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0083] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0084] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0085] See also Figure 1 as well as Figure 2 The present application provides a display panel 10, which includes a display area 11 and a frame area 12 located outside the display area 11. The display area 11 is mainly used to realize the display function of the display panel 10 and is a key area in the display panel 10. The frame area 12 is used to arrange wiring to support the display function of the display area 11. At the same time, the display panel 10 includes a substrate 110, a first functional layer 120 and a protective layer 130.

[0086] The substrate 110 plays a supporting role in the display panel 10, and can be a flexible substrate or a rigid substrate. When the substrate 110 is a flexible substrate, its material can be polyimide (PI), and when the substrate 110 is a rigid substrate, its material can be glass or metal. The present application does not limit the structure of the substrate 110.

[0087] The first functional layer 120 refers to a functional film layer in the display panel 10, for example, it can be an array layer, a light-emitting layer, a touch layer or a packaging layer, etc. A first grounding member 121 is provided in the first functional layer 120 to release static electricity in the display panel 10, and in order not to affect the function of the display area 11, the first grounding member 121 is located in the frame area 12.

[0088] The protective layer 130 plays a protective role in the display panel 10. The protective layer 130 is in direct contact with the first functional layer 120, and there is no film layer between the two. The protective layer 130 includes a first target area 131. The thickness of the protective layer 130 in the first target area 131 is less than the thickness of the protective layer 130 in other areas, and the orthographic projection of the protective layer 130 in the first target area 131 on the substrate 110 overlaps with the orthographic projection of the first grounding member 121 on the substrate 110 at least partially, that is, at least part of the protective layer 130 in the first target area 131 is located above the first grounding member 121. The fact that the thickness of the protective layer 130 in the first target area 131 is less than the thickness of the protective layer 130 in other areas means that the average thickness of the protective layer 130 in the first target area 131 is less than the average thickness of the protective layer 130 in other areas.

[0089] Normally, most of the static electricity on the display panel 10 accumulates on the side of the display panel 10. For example, during the copper rod test or the back pressure test, the static electricity accumulated on the side of the display panel 10 increases significantly, and the accumulated static electricity easily induces changes in the characteristics of the display panel 10 and causes the display panel 10 to turn green. However, in the solution of the present application, since the thickness of the protective layer 130 located in the first target area 131 is less than the thickness of the protective layer 130 in other areas, the static electricity accumulated on the side of the display panel 10 can preferentially pass through the protective layer 130 located in the first target area 131 to reach the first grounding member 121 and be released, thereby preventing the static electricity accumulated on the side of the display panel 10 from being transmitted from the side of the display panel 10 to the display area 11. Therefore, the solution of the present application can prevent static electricity from damaging the display panel 10 in the display area 11, thereby improving the yield and reliability of the display panel 10.

[0090] In one embodiment, see Figure 2 as well as Figure 3 , the orthographic projection of the protective layer 130 located in the first target area 131 on the substrate 110 covers the orthographic projection of the first grounding member 121 on the substrate 110. This setting can better direct static electricity into the first grounding member 121. Of course, in other embodiments, it can also be that: the orthographic projection of the protective layer 130 located in the first target area 131 on the substrate 110 partially overlaps with the orthographic projection of the first grounding member 121 on the substrate 110, and partially does not overlap.

[0091] In one embodiment, the orthographic projection of the protection layer 130 in the first target area 131 on the substrate 110 completely overlaps with the orthographic projection of the first grounding member 121 on the substrate 110 , and this arrangement can ensure the overall flatness of the display panel 10 .

[0092] Continue reading Figure 2 as well as Figure 3 , the protective layer 130 includes a first groove 132 located in the first target area 131. Specifically, the first groove 132 is formed on the protective layer 130 in the first target area 131, so that the thickness of the protective layer 130 in the first target area 131 is less than the thickness of the protective layer 130 in other areas. The first groove 132 is a blind groove or a through groove penetrating the protective layer 130. It can be understood that setting the first groove 132 as a through groove penetrating the protective layer 130 can allow more static electricity to pass through the protective layer 130 in the first target area 131 to reach the first grounding member 121 and be released.

[0093] In one embodiment, the display panel 10 further includes a first conductive sheet (not shown), which is disposed in the first groove 132. The first conductive sheet can guide more static electricity to the first grounding member 121 and be released. In one embodiment, the first groove 132 is a through groove that penetrates the protective layer 130, and the first conductive sheet disposed in the first groove 132 is electrically connected to the first grounding member 121. The first conductive sheet can be any metal conductive sheet such as a copper sheet, an iron sheet or an aluminum sheet, and the present application does not limit the material of the first conductive sheet.

[0094] In one embodiment, see Figure 3 , the orthographic projection of the first groove 132 on the substrate 110 covers the orthographic projection of the first grounding member 121 on the substrate 110, that is, the first grounding member 121 is exposed in the first groove 132, so that more static electricity directly reaches the first grounding member 121 and is released. Of course, in other embodiments, the orthographic projection of the first groove 132 on the substrate 110 may partially overlap with the orthographic projection of the first grounding member 121 on the substrate 110.

[0095] In one implementation, the orthographic projection of the first groove 132 on the substrate 110 completely overlaps with the orthographic projection of the first grounding member 121 on the substrate 110 , so as to ensure the flatness of the display panel 10 .

[0096] In one embodiment, continue to refer to Figure 2 There are multiple first grooves 132, and the multiple first grooves 132 are arranged at intervals, and the orthographic projection of each first groove 132 on the substrate 110 at least partially overlaps with the orthographic projection of the first grounding member 121 on the substrate 110, so that each first groove 132 can guide static electricity to the first grounding member 121, further improving the reliability of the display panel 10.

[0097] See also Figure 4 In one embodiment, the first grounding member 121 includes a first grounding trace 1211 and a first electrostatic transmission portion 1212 .

[0098] Combined with Figure 1 , the first grounding trace 1211 is arranged around the display area 11; the first static electricity transmission part 1212 is located on the side of the first grounding trace 1211 away from the display area 11 and is electrically connected to the first grounding trace 1211. The first static electricity transmission part 1212 has a stronger ability to attract static electricity accumulated on the side of the display panel 10, so that the first static electricity transmission part 1212 can attract more static electricity and connect it to the ground through the first grounding trace 1211, further avoiding damage to the display panel 10 caused by static electricity, and further ensuring the reliability of the display panel 10.

[0099] In one embodiment, in combination Figure 1 The distance L between the first ground trace 1211 and the outer edge of the frame area 12 is in the range of 20 to 150 microns, for example, the distance L is 20 microns, 50 microns, 80 microns, 100 microns or 150 microns to ensure the reliability of electrostatic transmission.

[0100] In one embodiment, the orthographic projections of the first grounding trace 1211 and the first static electricity transmission portion 1212 on the substrate 110 overlap at least partially with the orthographic projections of the protection layer 130 located in the first target area 131 on the substrate 110, so as to better release the static electricity in the display panel 10. In one embodiment, the orthographic projection of the first groove 132 on the substrate 110 covers the orthographic projections of the first grounding trace 1211 and the first static electricity transmission portion 1212 on the substrate 110.

[0101] In other embodiments, only the orthographic projection of the first grounding trace 1211 on the substrate 110 at least partially overlaps with the orthographic projection of the protective layer 130 located in the first target area 131 on the substrate 110, while the orthographic projection of the first static electricity transmission portion 1212 on the substrate 110 does not overlap with the orthographic projection of the protective layer 130 located in the first target area 131 on the substrate 110. For example, in one embodiment, the orthographic projection of the first groove 132 on the substrate 110 covers the orthographic projection of the first grounding trace 1211 on the substrate 110, and the orthographic projection of the first groove 132 on the substrate 110 is spaced from the orthographic projection of the first static electricity transmission portion 1212 on the substrate 110.

[0102] In one embodiment, the orthographic projection of the protection layer 130 in the first target area 131 on the substrate 110 covers the orthographic projection of the first ground trace 1211 on the substrate 110 and the orthographic projection of the first static electricity transmission portion 1212 on the substrate 110 .

[0103] Continue reading Figure 2 In one embodiment, when there are multiple first grooves 132 , at least some of the first grooves 132 are spaced apart in the width direction X of the first ground trace 1211 .

[0104] In other embodiments, in combination Figure 1 , when there are multiple first grooves 132, at least some of the first grooves 132 are spaced apart in the extension direction Y of the first ground trace 1211. Or in other embodiments, when there are multiple first grooves 132, some of the first grooves 132 are spaced apart in the width direction X of the first ground trace 1211, and some of the first grooves 132 are spaced apart in the extension direction Y of the first ground trace 1211.

[0105] In one embodiment, in the direction from the frame area 12 to the display area 11, the opening areas of the plurality of first grooves 132 decrease, that is, the closer to the display area 11, the smaller the opening area of ​​the first grooves 132, and the closer to the edge of the display panel 10, the larger the opening area of ​​the first grooves 132. The above arrangement allows most of the static energy accumulated on the side of the display panel 10 to enter the first grounding member 121 from the first grooves 132 at the edge, thereby preventing the static electricity from moving toward the display area 11, and further ensuring the reliability of the display panel 10.

[0106] In one embodiment, the plurality of first grooves 132 are arranged at equal intervals to reduce the difficulty of process preparation.

[0107] Continue reading Figure 5 In one embodiment, the first grounding trace 1211 includes a first grounding sub-trace 12111 and a second grounding sub-trace 12112 disposed outside the first grounding sub-trace 12111, wherein the orthographic projection of the protection layer 130 located in the first target area 131 on the substrate 110 covers the orthographic projection of the second grounding sub-trace 12112 on the substrate 110. Specifically, static electricity is basically accumulated on the side of the display panel 10, and the above-mentioned arrangement can reduce the distance of static electricity transmission from the side of the display panel 10 to the display area 11, so that static electricity can be directly connected to the ground from the second grounding sub-trace 12112.

[0108] In one embodiment, the orthographic projection of the protection layer 130 in the first target area 131 on the substrate 110 further covers the orthographic projection of the first grounding sub-line 12111 on the substrate 110 to release more static electricity and further improve the reliability of the display panel 10 .

[0109] In one embodiment, the first grounding sub-line 12111 is electrically connected to the second grounding sub-line 12112. In one embodiment, the first grounding sub-line 12111 and the second grounding sub-line 12112 are integrally formed. In another embodiment, the first grounding sub-line 12111 and the second grounding sub-line 12112 are independently provided, but are grounded separately. In yet another embodiment, Figure 4As shown, the first grounding sub-route 12111 and the second grounding sub-route 12112 are arranged at intervals.

[0110] In one embodiment, see Figure 5 , the orthographic projection of the first groove 132 on the substrate 110 covers the orthographic projection of the second grounding sub-line 12112 on the substrate 110. When the first groove 132 is a through groove penetrating the protection layer 130, when the second grounding sub-line 12112 is exposed in the first groove 132, at least part of the first grounding sub-line 12111 is exposed in another first groove 132.

[0111] In one embodiment, see Figure 6 , the display panel 10 further includes a second functional layer 140 .

[0112] The second functional layer 140 is disposed on the side of the protective layer 130 facing away from the substrate 110, wherein the second functional layer 140 includes a second target area 141, the thickness of the second functional layer 140 in the second target area 141 is less than the thickness of the second functional layer 140 in other areas, and the orthographic projections of the second functional layer 140 in the second target area 141 and the protective layer 130 in the first target area 131 on the substrate 110 at least partially overlap, that is, at least part of the second functional layer 140 in the second target area 141 is located above the first grounding member 121. The fact that the thickness of the second functional layer 140 in the second target area 141 is less than the thickness of the second functional layer 140 in other areas means that the average thickness of the second functional layer 140 in the second target area 141 is less than the average thickness of the second functional layer 140 in other areas.

[0113] Since the thickness of the second functional layer 140 located in the second target area 141 is less than the thickness of the second functional layer 140 in other areas, static electricity can preferentially pass through the second functional layer 140 located in the second target area 141 to reach the first grounding member 121 and be released, thereby preventing static electricity accumulated on the side of the display panel 10 from moving from the side of the display panel 10 to the display area 11.

[0114] In one embodiment, see Figure 6 , the orthographic projection of the second functional layer 140 in the second target area 141 on the substrate 110 covers the orthographic projection of the protective layer 130 in the first target area 131 on the substrate 110. This arrangement allows static electricity to pass through the second functional layer 140 in the second target area 141 and the protective layer 130 in the first target area 131 in sequence to reach the first grounding member 121 and be released, thereby ensuring smooth transmission of static electricity.

[0115] In one embodiment, see Figure 6The orthographic projection of the second functional layer 140 located in the second target area 141 on the substrate 110 completely overlaps with the orthographic projection of the protective layer 130 located in the first target area 131 on the substrate 110 to ensure the overall flatness of the display panel 10 .

[0116] See also Figure 6 , the second functional layer 140 includes a second groove 142 located in the second target area 141. Specifically, the second groove 142 is formed on the second functional layer 140 in the second target area 141, so that the thickness of the second functional layer 140 in the second target area 141 is less than the thickness of the second functional layer 140 in other areas. The second groove 142 is a blind groove or a through groove penetrating the second functional layer 140. It can be understood that the second groove 142 is set as a through groove penetrating the second functional layer 140, so that more static electricity can pass through the second functional layer 140 in the second target area 141 to reach the first grounding member 121 and be released.

[0117] In one embodiment, the display panel 10 further includes a second conductive sheet (not shown), which is disposed in the second groove 142. The second conductive sheet can guide more static electricity to the first grounding member 121 and be released. The second conductive sheet can be any metal conductive sheet such as a copper sheet, an iron sheet or an aluminum sheet, and the present application does not limit the material of the second conductive sheet.

[0118] In one embodiment, the orthographic projection of the second groove 142 on the substrate 110 covers the orthographic projection of the first grounding member 121 on the substrate 110, so that more electrostatic charges directly reach the first grounding member 121 and are released. Of course, in other embodiments, the orthographic projection of the second groove 142 on the substrate 110 may partially overlap with the orthographic projection of the first grounding member 121 on the substrate 110.

[0119] In one embodiment, the orthographic projection of the second groove 142 on the substrate 110 completely overlaps with the orthographic projection of the first grounding member 121 on the substrate 110 , so as to ensure the flatness of the display panel 10 .

[0120] In one embodiment, see Figure 6 There are multiple second grooves 142, which are arranged at intervals, and the orthographic projection of each second groove 142 on the substrate 110 at least partially overlaps with the orthographic projection of the first grounding member 121 on the substrate 110, so that each second groove 142 can guide static electricity to the first grounding member 121, further improving the reliability of the display panel 10.

[0121] In one embodiment, continue to refer to Figure 6When there are multiple second grooves 142, at least some of the second grooves 142 are spaced apart in the width direction X of the first ground trace 1211. In another embodiment, Figure 1 When there are multiple second grooves 142, at least some of the second grooves 142 are spaced apart in the extension direction Y of the first ground trace 1211. In another embodiment, when there are multiple second grooves 142, some of the second grooves 142 are spaced apart in the width direction X of the first ground trace 1211, and some of the second grooves 142 are spaced apart in the extension direction Y of the first ground trace 1211.

[0122] In one embodiment, continue to refer to Figure 6 The first grooves 132 and the second grooves 142 are arranged one by one, and the orthographic projections of the correspondingly arranged first grooves 132 and second grooves 142 on the substrate 110 completely overlap. That is, the number of the first grooves 132 and the second grooves 142 are equal.

[0123] In one embodiment, see Figure 6 , the second functional layer 140 includes an optical adhesive layer 144, and the optical adhesive layer 144 includes a second groove 142. In one embodiment, the second functional layer 140 further includes a polarizer layer 146 located on the side of the optical adhesive layer 144 facing away from the substrate 110, and the polarizer layer 146 also includes the second groove 142. It should be noted that in other embodiments, the polarizer layer 146 may also be located on the side of the optical adhesive layer 144 facing the substrate 110.

[0124] In one embodiment, continue to refer to Figure 6 The polarizer layer 146 and the optical adhesive layer 144 are both provided with a second groove 142 , and the second grooves 142 on the polarizer layer 146 and the optical adhesive layer 144 are connected to each other so that static electricity can reach the first grounding member 121 more smoothly.

[0125] In one embodiment, see Figure 7 as well as Figure 8 , the orthographic projection of the second functional layer 140 located in the second target area 141 on the substrate 110 covers the orthographic projection of the second grounding sub-line 12112 on the substrate 110. Specifically, static electricity is basically accumulated on the side of the display panel 10. The above arrangement can reduce the distance that static electricity moves from the side of the display panel 10 to the display area 11, so that static electricity can be directly connected to the ground from the second grounding sub-line 12112.

[0126] In one embodiment, the orthographic projection of the second functional layer 140 located in the second target area 141 on the substrate 110 further covers the orthographic projection of the first grounding sub-line 12111 on the substrate 110 to guide more static electricity to the first grounding member 121, thereby releasing more static electricity and improving the reliability of the display panel 10.

[0127] In one embodiment, see Figure 8 The second grounding sub-line 12112 is exposed in both the first through-slot groove 132 and the second through-slot groove 142 .

[0128] Continue reading Figure 2 The display panel 10 further includes a cover plate 150, which is disposed on the side of the second functional layer 140 away from the substrate 110, and the orthographic projection of the cover plate 150 on the substrate 110 covers the orthographic projection of the second functional layer 140, the protective layer 130, and the first functional layer 120 on the substrate 110. Specifically, the cover plate 150 can be a rigid cover plate or a flexible cover plate. When the cover plate 150 is a rigid cover plate, it can be made of polycarbonate (PC) or ethylene vinyl acetate (EVA). When the cover plate 150 is a flexible cover plate, it can be made of ultra-thin flexible electronic glass (UTG). The cover plate 150 plays a role in protecting the second functional layer 140, the protective layer 130, the first functional layer 120, etc.

[0129] See also Fig. 9 In another embodiment, the first functional layer 120 includes a first conductive layer 220, and the first conductive layer 220 includes a first grounding member 121 and a first touch electrode 122 located in the display area 11, wherein the first touch electrode 122 can be a TX touch electrode or an RX touch electrode, which is not limited here. In other words, the first functional layer 120 is a touch layer at this time. The first grounding member 121 and the first touch electrode 122 are made of the same material, so that during the preparation process, the first grounding member 121 and the first touch electrode 122 can be prepared in the same process, which can improve the preparation efficiency.

[0130] Continue reading Fig. 9 , the first functional layer 120 further includes an insulating layer 230 and a second conductive layer 240 .

[0131] The insulating layer 230 is arranged on the side of the first conductive layer 220 facing the substrate 110, and the insulating layer 230 is provided with a via 231; the second conductive layer 240 is arranged on the side of the insulating layer 230 facing the substrate 110, and the second conductive layer 240 includes a second grounding piece 241 located in the border area 12, and the second grounding piece 241 is electrically connected to the first grounding piece 121 through the hole 231.

[0132] The number of the via hole 231 may be one or more. The via hole 231 realizes the parallel connection between the first grounding member 121 and the second grounding member 241 , which can reduce the impedance of electrostatic transmission and improve the electrostatic release capability of the display panel 10 .

[0133] The structures of the first grounding member 121 and the second grounding member 241 may be the same or different, which is not limited here.

[0134] In one embodiment, continue to refer to Fig. 9 The second conductive layer 240 further includes a second touch electrode 242 located in the display area 11, that is, the second grounding member 241 and the second touch electrode 242 are disposed in the same layer. In one embodiment, the second grounding member 241 and the second touch electrode 242 are made of the same material, so that during the preparation process, the second grounding member 241 and the second touch electrode 242 can be prepared in the same process, which can improve the preparation efficiency.

[0135] When the first touch electrode 122 is a TX touch electrode, the second touch electrode 242 is a RX touch electrode; when the first touch electrode 122 is a RX touch electrode, the second touch electrode 242 is a TX touch electrode.

[0136] In other embodiments, the second touch electrode 242 may also be formed in the first conductive layer 220 . In this case, the intersection of the second touch electrode 242 and the first touch electrode 122 may be avoided by a bridge structure formed in the second conductive layer 240 .

[0137] In one embodiment, the orthographic projection of the protective layer 130 in the first target area 131 on the substrate 110 overlaps at least partially with the orthographic projection of the second grounding member 241 on the substrate 110, so that static electricity can be transmitted to the second grounding member 241 through the protective layer 130 in the first target area 131, further avoiding static electricity from being transmitted from the side of the display panel 10 to the display area 11, and further ensuring the reliability of the display panel 10. In one embodiment, the orthographic projection of the first groove 132 provided on the protective layer 130 on the substrate 110 overlaps at least partially with the orthographic projection of the second grounding member 241 on the substrate 110, for example, the orthographic projection of the first groove 132 provided on the protective layer 130 on the substrate 110 covers the orthographic projection of the second grounding member 241 on the substrate 110. Or when the protective layer 130 is provided with a plurality of first grooves 132, the orthographic projections of the plurality of first grooves 132 on the substrate 110 overlap at least partially with the orthographic projection of the second grounding member 241 on the substrate 110.

This arrangement can make it easier for static electricity to be transferred to the second grounding member 241, thereby improving the anti-static capability of the display panel 10.

[0139] In one embodiment, the first conductive layer 220 is provided with a second hollowed-out area, and the orthographic projection of the second hollowed-out area on the substrate 110 at least partially overlaps with the orthographic projection of the second grounding member 241 on the substrate 110. This setting can make it easier for static electricity to be transferred to the second grounding member 241, thereby improving the anti-static capability of the display panel 10.

[0140] In one embodiment, the first hollowed-out area is connected to the second hollowed-out area to ensure smooth transmission of static electricity.

[0141] In one implementation, the orthographic projections of the first grounding member 121 and the second grounding member 241 on the substrate 110 may be partially overlapped or completely overlapped.

[0142] In another embodiment, the first grounding member 121 and the second grounding member 241 are arranged at intervals on the substrate 110 in their positive projections, so that during the cutting process, even if one of the first grounding member 121 and the second grounding member 241 is damaged, the other one can still release static electricity. Therefore, the first grounding member 121 and the second grounding member 241 can be closer to the edge of the display panel 10, thereby reducing the width of the frame 12 and achieving a narrow frame of the display panel 10.

[0143] In one embodiment, when the first grounding member 121 includes a first grounding trace 1211 surrounding the display area 11 and the second grounding member 241 includes a second grounding trace surrounding the display area 11 , the first grounding trace 1211 and the second grounding trace are spaced apart in their orthographic projections on the substrate 110 .

This setting can extend the electrostatic release path of the first electrostatic transmission part 1212 and improve the electrostatic release effect.

[0145] In one embodiment, continue to refer to Figure 4The orthographic projection of the first static electricity transmission portion 1212 on the substrate 110 includes an arc shape, which further extends the static electricity release path and improves the reliability of the display panel 10.

The arrangement of the connecting sub-routing 12113 can improve the antistatic capability of the first grounding routing 1211.

[0150] In one embodiment, the first grounding sub-route 12111, the second grounding sub-route 12112, and the connecting sub-route 12113 are made of the same material. Specifically, using the same material to prepare the first grounding sub-route 12111, the second grounding sub-route 12112, and the connecting sub-route 12113 is conducive to saving process steps and improving preparation efficiency.

[0151] In one embodiment, the first grounding sub-route 12111, the second grounding sub-route 12112, and the connecting sub-route 12113 are integrally formed. Specifically, the first grounding sub-route 12111, the second grounding sub-route 12112, and the connecting sub-route 12113 are simultaneously prepared using the same process, which saves process steps, improves preparation efficiency, and ensures the connection effect between the three.

[0152] Continue reading Figure 4The first grounding member 121 further includes a connection block 1213 located between the first grounding trace 1211 and the first electrostatic transmission portion 1212, and the connection block 1213 electrically connects the first grounding trace 1211 and the first electrostatic transmission portion 1212. Specifically, the provision of the connection block 1213 increases the contact area between the first grounding trace 1211 and the first electrostatic transmission portion 1212, thereby ensuring the reliability of the connection between the first grounding trace 1211 and the first electrostatic transmission portion 1212.

[0156] In one embodiment, the plurality of first electrostatic transmission parts 1212 are arranged at equal intervals. In one embodiment, the structures of the plurality of first electrostatic transmission parts 1212 are completely the same, which facilitates the preparation of the first electrostatic transmission parts 1212, reduces the preparation difficulty, and ensures the preparation efficiency.
