This prevents negative charges from entering the display panel from the outer side, which would cause the light-emitting devices in the display panel to become brighter, resulting in a greenish tint across the entire screen, thus improving the display effect. Because the conductive portion is a solid structure formed by the solidification of the conductive liquid, the conductive liquid can better penetrate narrow gaps, which is beneficial for achieving a narrow bezel display module.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the film layer structure of a display module. The display module 00 may include: a display panel 01, a cover plate 02, and a first support and protective layer 03.

[0043] The display panel 01 in the display module 00 can be used to display images. Here, the display side of the display panel 01 is the side of the display panel 01 used to display images.

[0044] The cover plate 02 is located on the side of the display panel 01 that has the display side. In this way, the cover plate 02 can protect the display side of the display panel 01.

[0045] The first support protective layer 03 is located on the side of the display panel 01 away from the cover plate 02.

[0046] A portion of the negative charge generated by static electricity is distributed on the surface of the cover plate 02 on the side facing away from the display panel 01. Some of these negative charges can move and diffuse along the surface of the cover plate 02 due to mutual repulsion. As the negative charges diffuse along the surface of the cover plate 02 to its edge, they can diffuse through the outer side of the cover plate 02 to the surface of the cover plate 02 near the display panel 01. Furthermore, another portion of the negative charge can be directly conducted from the surface of the cover plate 01 to the surface of the cover plate 02 near the display panel 01.

[0047] During the process of bonding the cover plate 02 and the display panel 01 with optical adhesive, the optical adhesive will overflow, causing the outer side of the display panel 01 and the outer side of the first support protective layer 03 to come into contact with the optical adhesive. Furthermore, during the subsequent process of bonding the display module 00 and the middle frame with sealant, the sealant can also come into contact with the outer side of the display panel 01, the outer side of the first support protective layer 03, and the cover plate. This results in the negative charge that diffuses to the surface of the cover plate 02 near the display panel 01 being easily conducted and diffused to the display panel 01 and the first support protective layer 03 through the optical adhesive and sealant.

[0048] Negative charges entering the display panel 01 will make the light-emitting devices in the display panel 01 that emit green light brighter, resulting in the entire screen turning green. Furthermore, because the first support protective layer 03 is close to the driving backplate in the display panel 01, negative charges entering the first support protective layer 03 can form a voltage with the gate of the transistor in the driving backplate, affecting the electrical performance of the transistor and thus interfering with the display of the display panel 01.

[0049] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a top view of a display module provided in an embodiment of this application. Figure 3 yes Figure 2 The diagram shown illustrates the film structure of the display module at point A-A'. Figure 4 yes Figure 2 The diagram shows the film structure of the display module at point B-B'. The display module 000 includes: a display panel 100, a cover plate 100, a conductive support layer 300, and a conductive part 400.

[0050] The display panel in the display module 000 includes a first panel portion 110 and a second panel portion 120 disposed opposite to each other, and a panel bending portion 130 for connecting the first panel portion 110 and the second panel portion 120. That is, the panel bending portion 130 can be located between the first panel portion 110 and the second panel portion 120, and one side of the panel bending portion 130 can be connected to the first panel portion 110, and the other side of the panel bending portion 130 can be connected to the second panel portion 120. The first panel portion 110 has a display surface S, and the display module 000 can display an image through the display surface S of the first panel portion 110. A cover plate 200 in the display module 000 covers the first panel portion 110, and a conductive functional layer 300 is located on the side of the first panel portion 110 opposite to the cover plate 200.

[0051] The cover plate 200 in the display module 000 is located on the display side of the display panel 100. Here, the display side of the display panel 100 refers to the side of the display panel 100 used for displaying images. The display side of the display panel 100 can be fitted with the cover plate body 210 in the cover plate 200, so that the cover plate body 210 can protect the display side of the display panel 100. That is, the cover plate 200 is located on the side of the display panel 100 with the display surface S. The cover plate 200 may include: a cover plate body 210 covering the first panel portion 110, and an extension portion 220 connected to the cover plate body 210; at least a portion of the extension portion 220 is a curved portion 221 extending in an arc shape, and the surface of the curved portion 221 can be tangentially disposed with the surface of the cover plate body 210. And there is an accommodating space R between the curved portion 221 and the outer surface of the first panel portion 110. This accommodating space R can be used to accommodate conductive liquid.

[0052] The conductive support layer 300 in the display module 000 is located on the side of the first panel portion 110 facing away from the cover plate 200. Here, the conductive support layer 300 can be used to protect the side of the first panel portion 110 facing away from the display surface S, and the conductive support layer 300 is conductive, serving as a grounding component in the display module 000. That is, the conductive support layer 300 can be connected to the ground wire. For example, the conductive support layer 300 can be made of copper foil.

[0053] The conductive portion 400 in the display module 000 is located within the accommodating space R. The conductive portion 400 is in contact with the bent portion 221 and the conductive support layer 300. For example, Figure 3 and Figure 5 As shown, Figure 5 This is a schematic diagram of the film layer structure of a display module provided in an embodiment of this application. The conductive part 400 is in contact with the conductive support layer 300 on the side opposite to the first panel part 110. It should be noted that the conductive part 400 is a solid structure formed by the solidification of a conductive liquid. Figure 3 As shown, when the amount of conductive liquid sprayed is small, the conductive portion 400 formed after the conductive liquid solidifies can be a thin film that contacts the outer surface of the first panel portion 110, the surface of the curved portion 221 facing the display panel 100, and the surface of the conductive support layer 300 facing away from the first panel portion 110. Alternatively, as... Figure 5 As shown, when the amount of conductive liquid sprayed is large, the conductive part 400 formed after the conductive liquid solidifies can fill the entire accommodating space R.

[0054] In this embodiment of the application, the display module 000 further includes a first support and protective layer 500. The first support and protective layer 500 is located between the first panel portion 110 and the conductive support layer 300. The first support and protective layer 500 can be bonded to the side of the display panel 100 opposite to the display side, and the first support and protective layer 500 can be used to support the first panel portion 110.

[0055] like Figure 3 As shown, negative charges generated by static electricity are distributed on the surface of the cover plate 200 on the side facing away from the display panel 100. Some of these negative charges can move and diffuse along the surface of the cover plate 200 due to mutual repulsion. When the negative charges diffuse along the surface of the cover plate 200 to the edge of the cover plate 200, they can diffuse through the outer side of the cover plate 200 and converge in the conductive portion 400 surrounding the outer side of the first panel portion 110. Another portion of the negative charges can be conducted from the surface of the cover plate 200 to the side of the cover plate 200 closer to the display panel 100, and then conducted and converge in the conductive portion 400 that contacts the curved portion 221. Since the conductive portion 400 is in contact with the conductive support layer 300, all the negative charges conducted from the cover plate 200 to the conductive portion 400 can be conducted and diffused to the conductive support layer 300. In this way, negative charges can be released through the conductive part 400 and the conductive support layer 300, preventing negative charges from entering the display panel 100 from the outer side, which would cause the light-emitting devices in the display panel 100 to become brighter, resulting in a green screen phenomenon and thus a better display effect. Furthermore, since the conductive part 400 is a solid structure formed by the solidification of a conductive liquid, the conductive liquid can better penetrate narrow gaps, which is beneficial for achieving a narrow bezel display module 000.

[0056] Furthermore, since the negative charge on the cover plate 200 can be released through the conductive part 400, the negative charge will not accumulate in the first support protective layer 500. This avoids the situation where the distance between the first support protective layer 500 and the driving back plate in the first panel part 110 is too close, causing the accumulated charge in the first support protective layer 500 to generate a voltage between the gate of the transistor in the driving back plate, thereby affecting the electrical performance of the transistor, resulting in a better display effect of the display panel 100.

[0057] In summary, the display module provided in this application has a accommodating space for containing conductive liquid between the curved portion and the outer side of the first panel portion. The conductive liquid solidifies to form a conductive portion. This conductive portion contacts the curved portion and the conductive support layer. In this way, negative charges on the cover plate can be conducted and diffused to the conductive support layer through the conductive portion, and the negative charges can be released through the conductive portion and the conductive support layer. This prevents negative charges from entering the display panel from the outer side, which would cause the light-emitting devices emitting green light in the display panel to become brighter, resulting in a greenish tint across the entire screen, thus improving the display effect of the display panel. Since the conductive portion is a solid structure formed by the solidification of conductive liquid, the conductive liquid can better penetrate narrow gaps, which is beneficial for achieving a narrow bezel display module.

[0058] In the embodiments of this application, such as Figure 5 As shown, the display module 000 may further include an optical adhesive layer 600 and a polarizer 700 located between the cover plate body 210 and the first panel portion 110, with the polarizer 700 being closer to the first panel portion 110 than the optical adhesive layer 600. The optical adhesive layer 600 is used to bond the cover plate 200 to the polarizer 700, and is typically made of a transparent adhesive (e.g., acrylic adhesive). This ensures that light emitted from the display panel 100 passes through the optical adhesive layer 600 and the cover plate 200 before exiting. Furthermore, the optical adhesive layer 600 has good cushioning properties, thus reducing the probability of the cover plate 200 breaking after the front of the display module 000 is subjected to impact. The polarizer 700 can be bonded to the display side of the display panel 100. The polarizer 700 can reduce the reflectivity of the display panel 100 to ambient light, so as to ensure that the display area within the display panel 100 displays a better image.

[0059] The display module 000 may further include a first functional film layer 800 located between the first support protective layer 500 and the conductive support layer 300. The first functional film layer 800 includes a mesh adhesive layer, a foam layer, and a polyimide film layer stacked in a direction away from the first panel portion 110. One side of the mesh adhesive layer can be bonded to the side of the first support protective layer 500 opposite to the first panel portion 110. Here, the side of the mesh adhesive layer opposite to the first support protective layer 500 can be bonded to the side of the foam layer facing the first panel portion 110. The side of the foam layer opposite to the first panel portion 110 can be bonded to the polyimide film layer. The side of the polyimide film layer in the display module 000 opposite to the first panel portion 110 can be bonded to the conductive support layer 300, and the polyimide film layer enables electrical insulation between the first support protective layer 500 and the conductive support layer 300.

[0060] It should be noted that, because the first support protective layer 500 and the driving backplate in the first panel portion 110 are relatively close, if negative charges on the cover plate 200 enter the first support protective layer 500, causing a large amount of charge to accumulate in the first support protective layer 500, the accumulated charge in the first support protective layer 500 will generate a voltage with the gate of the transistor in the pixel circuit, thereby affecting the electrical performance of the transistor and causing abnormal display function of the display panel 100. Therefore, the resistance of the polarizer 700 can be lower than the resistance of the first support protective layer 500. In this way, the negative charges on the cover plate 200 are more easily conducted and diffused into the polarizer 700, avoiding the accumulation of a large amount of charge in the first support protective layer 500 and the generation of a voltage with the gate of the transistor in the pixel circuit, thus preventing the transistor's electrical performance from being affected.

[0061] It should also be noted that after the panel bending portion 130 in the display module 000 is bent, the second panel portion 120 also needs to be attached to the conductive support layer 300. For example, as shown... Figure 4 As shown, the display module 000 further includes a second support protective layer 900 and a support pillar 1000 located between the second panel portion 120 and the conductive support layer 300. The second support protective layer 900 can be used to support the second panel portion 120; the support pillar 1000 can be used to bond the conductive support layer 300 and the second support protective layer 900, and to support both the conductive support layer 300 and the second support protective layer 900.

[0062] Please refer to this application. Figure 6 , Figure 6This is a schematic diagram of the film layer structure of another display module provided in this application embodiment. The conductive support layer 300 may include: a conductive support layer body 310, and a covering portion 320 connected to the outer edge of the conductive support layer body 310. The conductive support layer body 310 is located on the side of the first panel portion 110 facing away from the cover plate 200, and is used to support the first panel portion 110. The covering portion 320 covers the outer side of the first panel portion 110 where the panel bending portion 130 is not provided. In this case, the covering portion 320 can effectively prevent negative charges in the cover plate 200 from contacting the outer side of the first panel portion 110 and the first support protective layer 500 where the panel bending portion 130 is not provided through the conductive portion 400, or through the portion overflowing from the optical adhesive layer 600, and thus preventing them from entering the first panel portion 110 and the first support protective layer 500. In this way, the display panel 100 will not exhibit a greenish tinge due to charge accumulation, resulting in a better display effect. Furthermore, the first support protective layer 500 will not generate voltage with the gate of the transistor in the pixel circuit due to accumulated charge, thus affecting the electrical performance of the transistor, resulting in a better display effect of the display panel 100. In addition, the increased contact area between the conductive support layer 300 and the conductive part 400 can effectively improve the release efficiency of negative charges in the cover plate 200 through the conductive part 400 and the conductive support layer 300.

[0063] In this configuration, the first support protective layer 500 is located between the first panel portion 110 and the conductive support layer body 310, and the covering portion 320 also covers the outer side of the first support protective layer 500 where the panel bending portion 130 is not located. The first functional film layer 800 can also extend between the covering portion 320 and the outer side of the first panel portion 110 where the panel bending portion 130 is not located. Thus, the covering portion 320 can be bonded to the outer side of the first panel portion 110 where the panel bending portion 130 is not located via the mesh adhesive layer in the first functional film layer 800. Furthermore, the polyimide film layer in the first functional film layer 800 is insulating, effectively preventing negative charges from entering the first panel portion 110 and the first support protective layer 500, thus avoiding the phenomenon of the entire screen turning green and abnormal transistor electrical performance, resulting in a better display effect for the display panel 100.

[0064] In the embodiments of this application, please refer to Figure 7 , Figure 7 This is a schematic diagram of the film structure of a display panel according to an embodiment of this application. The display panel 100 includes: a substrate 101, a light-shielding layer 102, multiple pixel driving circuits 103, and multiple light-emitting devices 104.

[0065] The light-shielding layer 102 in the display panel 100 is located on one side of the substrate 101. Multiple pixel driving circuits 103 in the display panel 100 are located on the side of the light-shielding layer 102 facing away from the substrate 101. Each pixel driving circuit 103 includes at least two transistors 103a and a storage capacitor 103b. The transistor 103a may include a first electrode 1031, a second electrode 1032, an active layer 1033, and a gate 1034. The gate 1034 is located on the side of the active layer 1033 facing away from the substrate 101, and the first electrode 1031 and the second electrode 1032 are also located on the side of the active layer 1033 facing away from the substrate 101. Here, the first electrode 1031 can be one of the source and drain of the transistor 103a, and the second electrode 1032 can be the other of the source and drain of the transistor 103a. Furthermore, the active layer 1033 in the transistor 103a may include a first conductor portion a and a second conductor portion b disposed opposite to each other, and a channel region c located between the first conductor portion a and the second conductor portion b.

[0066] In transistor 103a, the first electrode 1031 is electrically connected to the first conductor portion a, and the second electrode 1032 is electrically connected to the second conductor portion b. The orthogonal projection of the channel region c onto the substrate 100 lies within the orthogonal projection of the gate 1034 onto the substrate 100. Thus, when a gate drive signal is applied to the gate 1034, charge carriers can be generated in the channel region c, enabling conduction between the first conductor portion 221 and the second conductor portion 222.

[0067] It should be noted that the orthographic projection of the channel region c of at least a portion of the transistors 103a in the pixel driving circuit 103 onto the substrate 101 is located within the orthographic projection of the light-shielding layer 102 onto the substrate 101.

[0068] For example, the light-shielding layer 102 may include a plurality of light-shielding blocks 102a. The plurality of light-shielding blocks 102a may correspond to a plurality of pixel driving circuits 103. The orthographic projection of the channel region c of at least a portion of the transistors 103a in each pixel driving circuit 103 onto the substrate 101 lies within the orthographic projection of the corresponding light-shielding block 102a onto the substrate 101. Thus, the light-shielding layer 102a can serve as a light-shielding structure for the active layer 1033, blocking light incident from the outside onto the active layer 1033, preventing the active layer 1033 from being affected by external light, and improving the stability of the transistors 103a.

[0069] In the display panel 100, multiple light-emitting devices 104 are located on the side of multiple pixel driving circuits 103 facing away from the substrate 101, and the multiple light-emitting devices 104 are electrically connected to the multiple pixel driving circuits 103 respectively. In this way, the light emission of the corresponding light-emitting device 104 can be controlled by the pixel driving circuit 103.

[0070] In this application, the light-shielding layer 102 may further include a connecting lead 102b for connecting two adjacent light-shielding blocks 102a. Thus, each light-shielding block 102a in the light-shielding layer 102 can be connected via the connecting lead 102b, allowing the light-shielding layer 102 to be used to load an electrical signal with a fixed potential. For example, the fixed potential electrical signal can be a high-level power signal or a low-level power signal. Here, when the fixed potential electrical signal is a high-level power signal, the light-shielding layer 102 can be electrically connected to a high-level power signal line in the display panel 100; when the fixed potential electrical signal is a low-level power signal, the light-shielding layer 102 can be electrically connected to a low-level power signal line in the display panel 100. Both the high-level and low-level power signal lines can be electrically connected to each pixel driving circuit 103.

[0071] In this way, even if a large amount of negative charge accumulates in the first support protective layer 500, since the light-shielding layer 102 is located between the gate 1034 and the first support protective layer 500, and an electrical signal with a fixed potential is loaded on the light-shielding layer 102, voltage is avoided between the gate 1034 and the first support protective layer 500, thereby making the transistor 103a more stable and the display panel 100 more effective.

[0072] It should be noted that, Figure 7 The gate 1034 in the transistor 103a shown is located on the side of the active layer 1033 away from the substrate 101. In other possible embodiments, the gate 1034 may also be located on the side of the active layer 1033 closer to the substrate 101; or, the transistor 103a may also be a dual-gate structure, with one gate located on the side of the active layer 1033 away from the substrate 101 and the other gate located on the side of the active layer 1033 closer to the substrate 101.

[0073] In the embodiments of this application, please refer to Figure 8 , Figure 8 This is a top view of another display module provided in this application embodiment. The extensions 220 in the cover plate 200 are distributed around the cover plate body 210. In this case, the extensions 220 include: two first extensions 2201 disposed opposite each other in the first direction x, and a second extension 2202 and a third extension 2203 disposed opposite each other in the second direction y. The third extension 2203 can cover the panel bend 130. The first extensions 2201 are bends 221, and the conductive portion 400 includes: a first sub-conductive portion 410, which contacts the first extensions 2201 and the conductive support layer 300.

[0074] In this way, the negative charge on the surface of the cover plate 200 is conducted and diffused to the conductive support layer 300 through the first sub-conductive part 410. Thus, the negative charge can be released through the first sub-conductive part 410 and the conductive support layer 300, preventing negative charge from entering the display panel 100 from its outer side. This would prevent the light-emitting devices in the display panel 100 from becoming brighter, resulting in a greenish tint across the entire screen and thus improving the display effect of the display panel 100.

[0075] It should be noted that the second extension 2202 and the third extension 2203 have multiple possible implementations. The embodiments of this application will be illustrated by the following two possible implementations.

[0076] In the first possible implementation, such as Figure 8 As shown, both the second extension 2202 and the third extension 2203 are planar portions extending in a planar manner. In this case, since both the second extension 2202 and the third extension 2203 are planar portions extending in a planar manner, they cannot form a accommodating space R for containing conductive liquid with the outer surface of the first panel portion 110. Furthermore, since the conductive portion 400 is a solid structure formed after the conductive liquid has been solidified, the orthographic projection of the conductive portion 400 on the cover plate 200 does not coincide with the area where the second extension 2202 and the third extension 2203 are located.

[0077] In the second possible implementation, please refer to Figure 9 , Figure 9 This is a top view of another display module provided in this application embodiment. Both the second extension 2202 and the third extension 2203 are bent portions 221. Since the third extension 2203 covers the panel bend 130, and electronic components are disposed on the second panel portion 120 connected to the panel bend 130, the third extension 2203 does not have a conductive portion 400 to avoid interference from the conductive portion 400 formed by the cured conductive liquid. That is, the orthographic projection of the conductive portion 400 on the cover plate 200 does not coincide with the area where the third extension 2203 is located.

[0078] In this configuration, the conductive portion 400 may further include a second sub-conductive portion 420, which contacts the second extension 2202 and the conductive support layer 300. Negative charges on the surface of the cover plate 200 are conducted and diffused to the conductive support layer 300 through the second sub-conductive portion 420. This allows negative charges to be released through the second sub-conductive portion 420 and the conductive support layer 300, preventing negative charges from entering the display panel 100 from its outer surface. This would prevent the light-emitting devices in the display panel 100 from emitting green light from becoming brighter, resulting in a full-screen green tint and thus improving the display effect of the display panel 100.

[0079] It should be noted that, Figure 8 The schematic diagram of the film structure at C-C' and D-D' of the display panel 000 shown can be referenced. Figure 3 , Figure 5 or Figure 6 The diagram illustrates the membrane structure. Figure 9 The schematic diagrams of the film structure of the display panel 000 at E-E', F-F', and G-G' shown can also be referenced. Figure 3 , Figure 5 or Figure 6 The diagram below illustrates the membrane structure.

[0080] It should also be noted that the accompanying drawings in the above embodiments are illustrative examples of the display panel 100 not extending into the curved portion 221 of the cover plate 200. The edge portion of the display panel 100 may also extend into the curved portion 221 of the cover plate 200, so that the curved portion 221 of the cover plate 200 can also be used for display. This application does not limit this aspect.

[0081] In summary, the display module provided in this application has a accommodating space for containing conductive liquid between the curved portion and the outer side of the first panel portion. The conductive liquid solidifies to form a conductive portion. This conductive portion contacts the curved portion and the conductive support layer. In this way, negative charges on the cover plate can be conducted and diffused to the conductive support layer through the conductive portion, and the negative charges can be released through the conductive portion and the conductive support layer. This prevents negative charges from entering the display panel from the outer side, which would cause the light-emitting devices emitting green light in the display panel to become brighter, resulting in a greenish tint across the entire screen, thus improving the display effect of the display panel. Since the conductive portion is a solid structure formed by the solidification of conductive liquid, the conductive liquid can better penetrate narrow gaps, which is beneficial for achieving a narrow bezel display module.

[0082] This application also provides an electronic device, which may include: a housing, and a display module connected to the housing, wherein the display module is... Figures 2 to 9The display module 000 shown can be any product or component with a display function, such as electronic paper, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0083] It should be noted that in electronic devices including Figures 2 to 9 When the provided display module 000 has a conductive housing, the housing can also serve as a charge release structure for the display module 000, further improving the release efficiency of negative charges.

[0084] For example, please refer to Figure 10 , Figure 10 This is a schematic diagram of the film structure of an electronic device provided in an embodiment of this application. In the electronic device 001, the housing 1100 is a plastic shell made of non-conductive plastic material. The side of the housing 1100 facing the display module 000 has a metal film 1200. The metal film 1200 is in contact with the cover plate 200, and a zero potential signal is applied to the metal film 1200.

[0085] In this application, negative charges generated by static electricity are distributed on the surface of the cover plate 200 on the side opposite to the display panel 100. Due to mutual repulsion, the negative charges can move and diffuse along the surface of the cover plate 200. When the negative charges diffuse along the surface of the cover plate 200 to the edge of the cover plate 200, the negative charges can diffuse through the outer side of the cover plate 200 and gather in the metal film 1200 that contacts the extension 220 of the cover plate 200. In this way, the negative charges can be released through the metal film 1200, preventing the negative charges from entering the display panel 100 and the first support protective layer 500, so that the display effect of the display panel 100 is better.

[0086] In addition, please refer to Figure 11 , Figure 11 This is a top view of a housing provided in an embodiment of this application. The metal film 1200 may include an annular metal film 1210 distributed around the edge of the housing 1110. In this case, the edges of the cover plate 200 are all in contact with the annular metal film 1210, which can concentrate and guide the negative charges generated at various positions of the cover plate 200 to the annular metal film 1210, so that the negative charges are effectively released through the metal film 1200.

[0087] It should be noted that the electronic device 001 also includes a circuit board 1300. The circuit board 1300 is located between the display module 000 and the housing 1100, and has a zero-potential signal providing terminal 1310, which is electrically connected to the metal film 1200. For example, the zero-potential signal providing terminal 1310 can be electrically connected to the metal film 1200 via a lead 1320, allowing negative charges to be directed through the metal film 1200 to the zero-potential signal providing terminal 1310 and subsequently released.

[0088] In this configuration, the metal thin film 1200 may further comprise a plurality of strip-shaped metal thin films 1220, and at least a portion of the plurality of strip-shaped metal thin films 1220 may be connected to the annular metal thin film 1210. The extension direction of a portion of the plurality of strip-shaped metal thin films 1220 may be parallel to the second direction y, and the extension direction of another portion of the plurality of strip-shaped metal thin films 1220 may be parallel to the first direction x. Thus, the negative charge conducted and converged to the annular metal thin film 1210 can be rapidly conducted through the plurality of strip-shaped metal thin films 1220 to the zero-potential signal providing terminal 1310 and subsequently released.

[0089] For example, such as Figure 11 As shown, the metal thin film 1200 also includes three strip-shaped metal thin films 1220. Two of the strip-shaped metal thin films 1220 extend in a direction parallel to the second direction y and are connected to the annular metal thin film 1210. One strip-shaped metal thin film 1220 extends in a direction parallel to the first direction x and is connected to the two strip-shaped metal thin films 1220. The negative charge that is conducted and converged to the annular metal thin film 1210 is rapidly conducted through the two strip-shaped metal thin films 1220 extending in a direction parallel to the second direction y to the strip-shaped metal thin film 1220 extending in a direction parallel to the first direction x, and then led to the zero-potential signal providing terminal 1310 and released.

[0090] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.

[0092] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
