[0024] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are 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 are within the scope of protection of this application.

[0025] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0026] The electronic device provided in the embodiments of the present application is described below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0027] In an embodiment of the present application, an electronic device is provided, including: a display screen 1, including a display panel 101 and a wire structure 2 electrically connected to the display panel 101; a shell 3, the display screen 1 is arranged on one side of the shell 3, the shell 3 is provided with a conductive part, and a gap 4 is formed between the shell 3 and the display panel 101; a first electrostatic protection layer, opposite to the conductive part, the first electrostatic protection layer is conductive; a dielectric layer, provided between the first electrostatic protection layer and the conductive part; the first electrostatic protection layer, the dielectric layer and the conductive part form a capacitor structure.

[0028] In such Figures 1 to 3 In the illustrated embodiment, the display screen of the electronic device may be a foldable flexible display screen. The display screen includes a display panel and a wire structure electrically connected to the display panel. The wire structure includes a wiring structure externally connected to the display panel.

[0029] The display screen 1 is disposed on one side of a housing 3. The housing 3 is provided with a conductive portion 31, forming a gap 4 between the housing 3 and the display panel 101. The housing comprises the middle frame of the electronic device. That is, the housing comprises a support structure for carrying and protecting the display screen. The housing has a ground path. Specifically, the housing is entirely made of metal, with the metal housing itself forming the conductive portion. The housing may also comprise connected plastic and a conductive portion. The conductive portion may be embedded in the plastic or disposed on the surface of the plastic, and the conductive portion may be made of a conductive material such as metal.

[0030] There's a gap between the housing and the display of an electronic device, and the wire structure may be exposed in the gap, affecting the appearance of the device. To enhance the aesthetics of the electronic device, the electronic device also includes a decorative element, specifically a decorative ring around the edge of the device. The decorative element is inserted into the gap to secure it in place.

[0031] The first electrostatic protection layer is a conductive layer that is opposite to the conductive portion of the housing. A dielectric layer is provided between the first electrostatic protection layer and the conductive portion, thereby forming a capacitor structure through the first electrostatic protection layer, the dielectric layer, and the conductive portion. The first electrostatic protection layer can be directly printed on the surface of the decorative part of the electronic device using a printing direct structure (PDS) process, or it can be an additional conductive structure added within the gap.

[0032] like Figure 3 As shown, at least a portion of the conductive wire structure 2 connected to the display panel 101 is exposed in the gap 4. In the presence of static electricity, external static electricity can be returned to the ground through the first electrostatic protection layer, thereby effectively providing electrostatic protection for the display screen. In the absence of static electricity, the capacitor structure formed between the first electrostatic protection layer and the housing stabilizes the ground impedance of the first electrostatic protection layer and increases the capacitance between the electrostatic protection layer and the housing. This can effectively reduce the impact of the electrostatic protection layer on antenna performance while achieving its own electrostatic protection.

[0033] In some embodiments, the first electrostatic protection layer, the dielectric layer, and the conductive portion form an electrostatic release path for conducting static electricity through an electrostatic release path comprising a capacitor structure. Specifically, static electricity breaks through the capacitor structure and forms an electrostatic release path to be conducted to the housing via the first electrostatic protection layer, the dielectric layer, and the conductive portion in turn. This embodiment directly utilizes the capacitor structure to form an electrostatic release path to release static electricity, which can effectively prevent static electricity from entering the display panel through the exposed wire structure of the gap 4 and damaging the device. At the same time, when there is no static electricity or the static electricity is small, the capacitor structure formed between the first electrostatic protection layer and the housing can effectively reduce the impact of the electrostatic protection layer on the antenna performance.

[0034] If the housing is entirely metal, static electricity is directly grounded through the conductive portion and grounding path formed by the metal housing itself. If the housing includes a plastic frame, static electricity is grounded through the conductive portion fixed to the plastic frame and the grounding path. The grounding path can be a wire structure embedded in the plastic frame or provided on the surface of the plastic frame.

[0035] like Figure 1 As shown, the electronic device further includes an antenna setting area 100 , and the electrostatic discharge path is located in the antenna setting area 100 .

[0036] The electronic device further includes an antenna, which is located at an outer edge of the electronic device to receive and transmit signals. The antenna installation area 100 is the area on the electronic device where the antenna is installed.

[0037] Because the first electrostatic protection layer in the capacitor structure is a conductive layer, if the electrostatic discharge path is located within the antenna installation area of ​​the electronic device, directly grounding the electrostatic protection layer to prevent static electricity will affect the performance of the antenna due to resonance. Therefore, grounding the electrostatic protection layer located in the antenna installation area 100 through the capacitor structure can effectively reduce the impact of the electrostatic protection layer on antenna performance.

[0038] If static electricity exists, it is introduced into the first electrostatic protection layer, breaks through the dielectric layer and is introduced into the conductive part. The static electricity is then coupled back to the ground through the shell, and the static electricity is released through capacitive coupling. The capacitor structure formed by the first electrostatic protection layer, the dielectric layer and the conductive part is equivalent to connecting a capacitor with a positive infinite DC impedance between the first electrostatic protection layer and the shell, thereby stabilizing the ground impedance of the electrostatic protection layer. In this way, the display screen can be prevented from being damaged by static electricity by adding an electrostatic protection layer in the antenna setting area, and the adverse effects of the added electrostatic protection layer on the antenna in the antenna setting area can be minimized.

[0039] exist Figure 2 In the illustrated embodiment, the dielectric layer includes an anodized layer 5 provided on the shell 3, and the anodized layer 5 includes a first portion of the anodized layer directly opposite to the first electrostatic protection layer 81 and a second portion of the anodized layer staggered from the first electrostatic protection layer, and the thickness of the first portion of the anodized layer is less than the thickness of the second portion of the anodized layer.

[0040] The inner side of the housing is coated with an anodized layer. The anodized layer consists of two parts: a first anodized layer directly opposite the first electrostatic shielding layer, and a second anodized layer offset from the first electrostatic shielding layer. The second anodized layer is thicker and serves as insulation for the housing. The first anodized layer is thinner, forming a dielectric layer that is more susceptible to static electricity breakdown. This, together with the first electrostatic shielding layer and the conductive portion, forms a capacitor structure that allows static electricity to be discharged through the electrostatic discharge path of the capacitor structure.

[0041] In the case where the capacitor structure is used to conduct static electricity through the electrostatic discharge path of the capacitor structure, the thicker the anodized layer, the stronger the insulation performance; the thinner the anodized layer, the weaker the insulation performance, and the lower the threshold voltage required for static electricity to break through the thinner anodized layer. The thickness of the first portion of the anodized layer is thinner than that of the second portion of the anodized layer. Therefore, after static electricity is introduced into the first electrostatic shielding layer, if the threshold voltage of the static electricity discharge is sufficient to break through the first portion of the anodized layer of corresponding thickness, the static electricity is introduced into the conductive portion and coupled back to the ground through the housing, thereby being released.

[0042] like Figure 4 As shown, the dielectric layer includes an anodized layer 5 provided on the conductive portion 31 , and the anodized layer 5 has at least one opening 51 to form the electrostatic discharge path.

[0043] In this embodiment, the dielectric layer is an anodic oxide layer, which is disposed between the first electrostatic protection layer and the conductive portion. Figure 2 As shown, the conductive portion 31 is part of the housing 3. An anodized layer 5 is disposed between the first electrostatic protection layer 81 and the conductive portion 31. Openings 51 are provided in the anodized layer 5 to allow air to pass through. Because the threshold voltage for static electricity to break down through the air dielectric layer is much lower than the threshold voltage for static electricity to break down through the anodized layer 5, these openings 51 significantly reduce the threshold voltage for static electricity discharge, greatly increasing the reliability of the electrostatic discharge path formed by the capacitor structure in providing electrostatic protection to the display screen 1.

[0044] Furthermore, the electronic device further includes a conductive adhesive 6 disposed between the anodized layer and the first electrostatic protection layer. The conductive adhesive 6 contains conductive particles, and the particle size of the conductive particles is larger than the aperture of the opening 51 .

[0045] Combine Figure 2 and Figure 4 A conductive glue 6 is added between the open anodized layer 5 and the first electrostatic protection layer 81. The conductive glue 6 is essentially metal particles conducting electricity. The conductive particles are large, and the particle size of the conductive particles is larger than the aperture of the opening 51 on the anodized layer 5. Air can pass through but the conductive glue cannot pass through, which is conducive to the formation of an air layer in the opening 51.

[0046] Opening 51 is formed in the first portion of the anodized layer. Conductive adhesive 6 is filled between the first electrostatic shielding layer 81 and the anodized layer 5. A first surface 65 of the conductive adhesive 6 contacts the first electrostatic shielding layer, and a second surface of the conductive adhesive 6, opposite the first surface 65, contacts the anodized layer 5 having opening 51. The anodized layer 5 is disposed on the conductive portion 31.

[0047] Conductive adhesive 6 not only secures the first electrostatic shield 5 but also reduces the distance over which static electricity is released, thereby lowering the threshold voltage. This allows low-voltage static electricity, for example, of 1-4 kV, to be released through the conductive portion toward the housing, preventing low-voltage static electricity from being released into the conductor structure and damaging the display screen in the absence of the conductive adhesive. Furthermore, conductive adhesive 6 increases the capacitance of the capacitor structure. In the absence of static electricity, the high capacitance structure further minimizes the impact of the electrostatic shield on antenna performance.

[0048] The electrostatic discharge path formed by the first electrostatic protection layer 81, the conductive adhesive 6, the anodized layer 5 with the opening 51 and the conductive part 31 is as shown in FIG. Figure 5 As shown, static electricity is first released to the conductive glue 6 through the electrostatic DC release path (solid arrow) corresponding to the first electrostatic protection layer 81 and the conductive glue 6, and then released to the conductive part 31 through the electrostatic coupling release path (dashed arrow) corresponding to the capacitor structure formed by the conductive glue 6, the anodized layer 5 with the opening 51 and the conductive part 31, and then discharged to the conductive part 31 through the grounding of the shell 3 connected to the conductive part 31.

[0049] like Figure 6 As shown, the electronic device also includes a conductive adhesive 6, and the first electrostatic protection layer 81 is fixed to the shell through the conductive adhesive 6. The conductive adhesive 6 is located between the dielectric layer and the first electrostatic protection layer 81. The first electrostatic protection layer, the conductive adhesive, the dielectric layer and the conductive part form an electrostatic release path.

[0050] As previously mentioned, the added conductive adhesive 6 not only secures the first electrostatic shielding layer 81 but also reduces the threshold voltage for electrostatic discharge when the capacitor structure serves as an electrostatic discharge path. Furthermore, the conductive adhesive 6 increases the capacitance of the capacitor structure. In the absence of static electricity, the large capacitor structure further minimizes the impact of the electrostatic shielding layer on antenna performance.

[0051] The electrostatic discharge path formed by the first electrostatic protection layer 81, the conductive adhesive 6, the anodized layer 5 and the conductive portion 31 is as follows. Figure 6 As shown, from Figure 6 It can be seen that static electricity is first released to the conductive glue 6 through the electrostatic DC release path (solid arrow) corresponding to the first electrostatic protection layer 81 and the conductive glue 6, and then released to the conductive part through the electrostatic coupling release path (dashed arrow) corresponding to the capacitor structure formed by the conductive glue 6, the anodized layer 5 and the conductive part 31, and then discharged to the conductive part through the grounding of the shell 3 connected to the conductive part 31.

[0052] This embodiment and Figure 5 The difference of the embodiment shown is that no opening 51 is provided on the anodized layer. Figure 6 The anodic oxide layer of the embodiment Figure 5 When the thickness of the anodized layer of the embodiment is the same, Figure 5 The anodized layer of the embodiment has open pores, so Figure 5 The threshold voltage of electrostatic discharge in the embodiment is less than Figure 6 Example of .

[0053] Optionally, the shell 3 has a bearing surface 33 for bearing the display screen 1, the bearing surface 33 is provided with a groove 11, the groove 11 extends along the edge of the display screen 1, and the first electrostatic protection layer is inserted in the groove 1; the conductive part, the dielectric layer and the first electrostatic protection layer are opposite to and form an electrostatic release path of the capacitor structure.

[0054] refer to Figure 1 and Figure 2 The shell 3 is used to support the bearing surface 33 of the display screen 1, that is, the shell surface parallel to the light-emitting surface of the display screen 1. A groove 11 is provided on the bearing surface 33, and the groove 11 extends along the edge of the display screen 1. The first electrostatic protection layer 81 can be inserted into the groove 11.

[0055] In this embodiment, the conductive portion 31 is a part of the housing 3, such as Figure 2 As shown in the enlarged view of the dotted area, the first electrostatic protection layer 81 is inserted into the groove 4 of the housing 3. The conductive portion 31, the dielectric layer including the anodized layer 5, and the first electrostatic protection layer 81 are aligned to form an electrostatic discharge path for the capacitor structure. Furthermore, a gap 14 is formed between the conductive portion 31 of the housing 3 and the display panel 101.

[0056] Optionally, the conductive portion is located at the edge of the supporting surface 33 and protrudes from the supporting surface 33 , so that the conductive portion is opposite to the side wall of the display panel 101 to limit the display screen 1 , and the groove 11 extends to the conductive portion.

[0057] In this embodiment, the conductive portion is a part of the housing, such as Figure 2 As shown, the conductive portion 31 is located at the edge of the bearing surface 33 of the housing 3 and protrudes from the bearing surface 33, so that the conductive portion 31 is opposite to the side wall of the display panel 101 to limit the display screen 1. Figure 2 As shown, the groove 4 extends to the conductive portion 31 .

[0058] Optionally, the conductive part is opposite to the side of the display panel 101, and the gap 4 is formed between the conductive part and the display panel. One end of the first electrostatic protection layer is located in the gap 4, and the other end of the first electrostatic protection layer extends toward the opening of the gap 4 and protrudes from the display screen 1 and / or the shell 3.

[0059] like Figure 2 As shown, the conductive part 31 is opposite to the side of the display panel 101, and a gap 4 is formed between the conductive part 31 and the display panel 101. One end of the first electrostatic protection layer 81 is located in the gap 4, and the other end of the first electrostatic protection layer 81 extends toward the opening of the gap 4 and protrudes from the display screen 1 and / or the shell 3.

[0060] In this way, when a static electricity source, such as a human hand, touches an electronic device, it will first contact the first electrostatic protection layer protruding from the display screen and / or the shell, so that the static electricity is preferentially released through the first electrostatic protection layer, effectively preventing static electricity from damaging other devices.

[0061] Figure 7is a schematic diagram of the structure of the capacitor structure in one embodiment of the present application. Figure 7 In the embodiment shown, the dielectric layer is an air layer, one side of the conductive part 31 is fixed in the gap 4, and the other side of the conductive part 31 extends toward the opening of the gap 4; the first electrostatic protection layer 81 is stacked directly above the conductive part 31 and separated from the conductive part 31 to form a gap 14 to accommodate the dielectric layer.

[0062] Combine Figure 7 , the conductive part 31 is fixed to the shell 3. In this embodiment, the conductive part 31 is attached to the shell 3 by a conductive adhesive 6. Specifically, one side of the conductive part 31 is fixed in the gap 4 formed between the shell 3 and the display panel 101, and the other side of the conductive part 31 extends toward the opening of the gap 4. The first electrostatic protection layer 81 is stacked directly above the conductive part 31 and separated from the conductive part 31 to form a gap 14. The gap 14 forms a dielectric layer of air. Thus, the conductive part 31, the air layer and the first electrostatic protection layer 81 form a parallel plate equivalent capacitor structure, and the electrostatic release path corresponding to the capacitor structure is as follows Figure 8 As indicated by the arrow.

[0063] When the static electricity on the electronic device is coupled back to the ground through the capacitor structure formed by the conductive part 31 separated by the first electrostatic protection layer 81, the static electricity is directly released through the first electrostatic protection layer 81, breaks through the air layer in the gap 14, and releases the static electricity coupling to the conductive part 31, and then is introduced into the shell 3 through the conductive part 31 and the conductive glue 6.

[0064] When the static electricity on the electronic device is not coupled back to the ground through the capacitor structure formed by the first electrostatic protection layer 81 and the spaced conductive part 31, the DC impedance of the capacitor structure formed between the first electrostatic protection layer 81 and the conductive part 31 fixed to the shell 3 is close to infinity, which can effectively reduce the impact on the antenna performance.

[0065] Furthermore, the shell 3 is provided with a groove 11, which extends around the display screen 1, and the conductive part is fixed to the groove 11 by conductive glue. The end face of the conductive part 31 facing away from the groove 11 is opposite to the first electrostatic protection layer 81 and forms the gap 14. The first electrostatic protection layer 81 is provided on the display side of the display panel 101.

[0066] refer to Figure 1 A groove 11 extending along the edge of the display screen is provided on the shell 3. The conductive part 31 is fixed to the groove 11 by a conductive adhesive 6. The conductive part 31 can be formed at a corresponding position on the inner side of the decorative part by a printing direct molding process. The first electrostatic protection layer 81 can also be formed at a corresponding position on the inner side of the decorative part by a printing direct molding process.

[0067] like Figure 7 As shown, the end surface of the conductive portion 31 facing away from the groove 11 is also opposite to the first electrostatic protection layer 81 and forms a gap 14 of an air layer.

[0068] As described above, the conductive portion 31 and the first electrostatic protection layer 81 form a capacitor structure through the gap 14 of the air layer. The end surface structures facing the conductive portion 31 and the first electrostatic protection layer 81 are different, and the shapes of the corresponding gaps 14 are also different.

[0069] In such Figure 8 In the embodiment shown, the end surface of the conductive portion 31 facing away from the groove 11 and directly facing the first electrostatic protection layer 81 is a plane, and the side of the first electrostatic protection layer 81 facing the conductive portion 31 is also a plane, forming a parallel planar capacitor between the two.

[0070] Optionally, the end face of the conductive part 31 facing away from the groove 11 is opposite to the first electrostatic protection layer 81 and forms the gap 14, the end face of the conductive part 31 facing away from the groove 11 has a first protrusion structure 931, and the first electrostatic protection layer is also provided with a second protrusion structure 831 matching the first protrusion structure 931 on the side close to the conductive part; the first protrusion structure 931, the second protrusion structure 831 and the dielectric layer located between the first protrusion structure 931 and the second protrusion structure 831 form the electrostatic release path.

[0071] In such Figure 9 In the illustrated embodiment, the end surface of the conductive portion 31 facing away from the groove 11 is provided with a sawtooth-shaped first protrusion structure 931 , and correspondingly, the first electrostatic protection layer 81 facing and close to the conductive portion 31 is also provided with the same sawtooth-shaped second protrusion structure 831 .

[0072] In such Figure 10 In the embodiment shown, the end surface of the conductive portion 31 facing away from the groove 11 is provided with a block-shaped first protruding structure 931. The first electrostatic protection layer 81 facing and close to the conductive portion 31 is also provided with a second protruding structure 831 of the same block shape, and the protruding portion of the first protruding structure 931 of the conductive portion 31 is staggered with the protruding portion of the second protruding structure 831 of the first electrostatic protection layer 81. Figure 9 The difference between the illustrated embodiment and the embodiment is that the end surface of the first protruding structure 931 is a plane, that is, the first protruding structure 931 is a rectangular block structure.

[0073] In such Figure 11 In the embodiment shown, the sawtooth-shaped first protrusion structure 931 of the conductive portion 31 and the sawtooth-shaped second protrusion structure 831 of the first electrostatic protection layer 81 are facing each other. Figure 9In the embodiment, the sawtooth-shaped first protruding structure 931 of the conductive portion 31 and the sawtooth-shaped second protruding structure 831 of the first electrostatic protection layer 81 have sawtooth tips that are parallel and staggered.

[0074] Optionally, the minimum distance of the interval 14 is less than 0.3 mm.

[0075] By providing an air layer gap 14 less than 0.3 mm between the first electrostatic protection layer 81 provided on the display side of the display panel 101 and the conductive portion 31 connected to the housing 3 , the reliability of the electrostatic protection function can be ensured.

[0076] Furthermore, for the conductive portion located in the antenna mounting area, a larger width Db generally indicates a lower resistance, less prone to passivation during electrostatic discharge, and a longer lifespan. However, if the width is too wide, it reduces antenna clearance and affects antenna performance.

[0077] like Figure 7 As shown, the housing 3 has a bearing surface 33 for bearing the display screen 1 , the first electrostatic protection layer 81 extends in a direction parallel to the bearing surface 33 , and the conductive portion 31 extends in a direction perpendicular to the bearing surface 33 .

[0078] Combine Figure 1 and Figure 7 The housing 3 supports the display screen, and the first electrostatic protection layer 81 extends parallel to the supporting surface 33, that is, parallel to the display side of the display panel 101. The first electrostatic protection layer 81 can be directly printed on the decorative member that protects the display screen using a printing direct molding process at a corresponding position, parallel to the display side of the display panel 101. The conductive portion 31 can be formed on the inner side of the decorative member using a printing direct molding process at a corresponding position, perpendicular to the display side of the display panel 101, and therefore perpendicular to the supporting surface 33 of the housing 3.

[0079] refer to Figure 7 The conductive portion 31 extends in a direction perpendicular to the bearing surface 33 of the housing 3 and is separated from and spaced apart from the first electrostatic protection layer 81 , forming a capacitor structure for electrostatic discharge through the air layer corresponding to the gap 14 .

[0080] The electronic device also includes a decorative piece 15 as shown in the figure, which has a first decorative part 151 superimposed on the display side of the display screen 1 and a second decorative part 153 inserted in the gap 4, and the first decorative part 151 and the second decorative part 153 are connected; the first electrostatic protection layer 81 is provided on the first decorative part 151, and the conductive part 31 is provided on the second decorative part 153.

[0081] Combine Figure 1In this embodiment, the first decorative portion 151 of the decorative element 15 is superimposed on the display side of the display screen, and the second decorative portion 153 of the decorative element 15 is fixed to the housing 3 via the slot 11 on the housing 3. The first decorative portion 151 and the second decorative portion 153 are connected as a whole. The first electrostatic protection layer 81 is formed inside the first decorative portion 151 through a printing direct molding process and is opposite to the display side of the display screen. The conductive portion 31 is formed inside the second decorative portion 153 through a printing direct molding process and forms a corresponding air layer gap 14 with the first electrostatic protection layer 81 on the first decorative portion 151.

[0082] In some embodiments, the electronic device further includes a second electrostatic protection layer 85, which is connected to the first electrostatic protection layer and extends to the display side of the display panel 101; the shell 3 has a grounding path, and the second electrostatic protection layer 85 is in direct contact with the shell 3 and grounded.

[0083] like Figure 1 As shown, the second electrostatic protection layer 85 is a conductive layer stacked on the display side of the display panel 101 , and the second electrostatic protection layer 85 is connected to the first electrostatic protection layer 81 at multiple locations.

[0084] exist Figure 12 In the illustrated embodiment, the second electrostatic protection layer 85 is a conductive layer stacked on the display side of the display panel 101 , and the second electrostatic protection layer 85 is connected to the first electrostatic protection layer 81 at multiple locations.

[0085] Figure 1 In the illustrated embodiment, the second electrostatic protection layer 85 includes a plurality of segmented conductive layers, and the second electrostatic protection layer 85 has segments that are completely located within the antenna placement area 100 . Figure 12 In the illustrated embodiment, the second electrostatic protection layer 85 is a continuously extending conductive layer, that is, the grounding point of the second electrostatic protection layer 85 is located outside the antenna arrangement area 100 .

[0086] Since the grounding point of the second electrostatic protection layer 85 outside the antenna setting area 100 has little effect on the antenna performance, the grounding point of the second electrostatic protection layer 85 outside the antenna setting area 100 can be directly grounded to the housing 3. Figure 12 As shown, the end 8501 of the second electrostatic protection layer 85 outside the antenna setting area 100 is a grounding point. The second electrostatic protection layer 85 at this grounding point is in direct contact with the housing 3 and electrically connected to the ground. Optionally, the second electrostatic protection layer 85 can extend into the groove 11 at this grounding point, that is, the second electrostatic protection layer 85 extends into the gap between the display panel and the housing to facilitate direct contact and conduction with the housing.

[0087] exist Figure 1In the illustrated embodiment, the second electrostatic shielding layer 85 has a segment located entirely within the antenna placement area 100, and the grounding point of this segment must be located within the antenna placement area 100. To reduce the impact of this segment on antenna performance, the second electrostatic shielding layer 85 of this segment should be grounded via an electrostatic discharge path including the capacitor structure described above.

[0088] Specifically, the second electrostatic protection layer 85 is connected to the first electrostatic protection layer and extends to the display side of the display panel 101. The first electrostatic protection layer is arranged in the gap 4 between the shell 3 and the display panel 101. The second electrostatic protection layer 85 is grounded through the electrostatic release path.

[0089] In such Figure 1 and Figure 2 In the illustrated embodiment, the end portion 8503 of the second electrostatic shielding layer 85 located within the antenna arrangement area 100 is grounded to the first electrostatic shielding layer 81, which forms an electrostatic discharge path, and extends to the display side of the display panel 101. The first electrostatic shielding layer 81 is located in the gap 4 between the housing 3 and the display panel 101. Thus, static electricity can be directly discharged to the second electrostatic shielding layer 85. Then, a capacitor structure is formed through the first electrostatic shielding layer 81, the dielectric layer including the anodized layer 5, and the conductive portion 31, thereby coupling the static electricity 8 on the second electrostatic shielding layer 85 to the housing 3.

[0090] The dielectric layer here may also be the air layer as described in the previous embodiment, which will not be described in detail here.

[0091] Furthermore, the second electrostatic protection layer 85 extends around the edge of the display panel 101 close to the wire structure 2, and the first electrostatic protection layer is provided at the end of the second electrostatic protection layer 85 away from the wire structure 2 to form a ground connection point.

[0092] like Figure 3 As shown, the wire structure 2 is located between the housing 3 and the display panel of the display screen 1 and is exposed through the gap. A second electrostatic protection layer 85 extends around the edge of the display panel 101 near the end of the cable to prevent static electricity from entering the display screen through the cable and damaging related components.

[0093] Optionally, the orthographic projection of the second electrostatic protection layer 85 on the plane where the display panel is located completely covers the gap 4. The orthographic projections of the end 8501 of the second electrostatic protection layer 85 and the end 8503 remote from the end 8501 on the plane where the display panel is located are respectively located on opposite sides of the orthographic projection of the wire structure 2 on the plane where the display panel is located, thereby ensuring that the second electrostatic protection layer 85 can be fully disposed around the wire structure, effectively preventing static electricity from being discharged to the wire structure.

[0094] Furthermore, the electronic device also includes a decorative piece 15, which has a first decorative part 151 stacked on the display side of the display screen and a second decorative part 153 inserted in the gap 4, and the first decorative part 151 and the second decorative part 153 are connected; the first electrostatic protection layer is provided on the second decorative part, and the second electrostatic protection layer 85 is provided on the first decorative part.

[0095] like Figure 1 As shown, the first decorative portion 151 of the decorative member 15 is superimposed on the display side of the display screen 1, and the second decorative portion 153 of the decorative member 15 is fixed to the housing 3 via the slot 11 on the housing 3. The first decorative portion 151 and the second decorative portion 153 are connected as a whole. In this embodiment, the second electrostatic protection layer 81 can be formed inside the first decorative portion 153 through a printing direct molding process, and is opposite to the display side of the display screen 1. The first electrostatic protection layer 81 can be formed inside the second decorative portion 153 through a printing direct molding process.

[0096] Optionally, the electronic device also includes an antenna setting area 100; the second electrostatic protection layer 85 includes a first electrostatic protection segment 851 and a second electrostatic protection segment 853, the first electrostatic protection segment 851 and the second electrostatic protection segment 853 are separated and spaced apart, the first electrostatic protection segment 851 has a first grounding connection point, and the first grounding connection point is located inside the antenna setting area 100; the second electrostatic protection segment 853 has a second grounding connection point, and the second grounding connection point is located outside the antenna setting area 100; the first electrostatic protection layer is connected to the first grounding connection point of the first electrostatic protection segment 851, and the first grounding connection point is grounded through the electrostatic release path; the second grounding connection point of the second electrostatic protection segment 853 is in direct contact and conduction with the shell 3, and is grounded through the grounding path of the shell 3.

[0097] In this embodiment, Figure 1 As shown, the second electrostatic protection layer 85 extending on the display side of the display screen 1 is divided into a first electrostatic protection segment 851 and a second electrostatic protection segment 853. The first electrostatic protection segment 851 and the second electrostatic protection segment 853 are separated by a distance, thereby forming a gap D1. The first electrostatic protection segment 851 is connected to the first electrostatic protection layer 81 at a corresponding ground connection point, and is used to discharge static electricity 8 through the first electrostatic protection layer 81 provided at the ground connection point to the corresponding housing 3.

[0098] like Figure 1As shown, the first ground connection point on the first electrostatic protection segment 851 is located within the antenna installation area 100. The first electrostatic protection layer 81 is connected to the first ground connection point of the first electrostatic protection segment 851, and the first ground connection point of the first electrostatic protection segment 851 is grounded via an electrostatic discharge path. This allows the ground connection point located within the antenna installation area 100 to be grounded via the electrostatic discharge path including the capacitor structure, achieving electrostatic coupling discharge. This not only meets electrostatic protection requirements but also minimizes the impact on the antenna.

[0099] The second grounding connection point on the second electrostatic protection segment 853 is located outside the antenna setting area 100. The end 8501 of the second electrostatic protection segment 853 outside the antenna setting area 100 is the second grounding connection point. The second electrostatic protection layer 85 at the second grounding point is in direct contact with the shell 3 and electrically connected to the ground, thereby realizing direct release of static DC.

[0100] The second ground connection point set at the end 8501 of the second electrostatic protection section 853 is located outside the antenna setting area 100, away from the antenna of the electronic device. Therefore, the static electricity returning to the ground through the second ground connection point has little effect on the antenna performance, so the capacitor structure as described above can be omitted.

[0101] It should be noted that the second electrostatic protection layer including the first electrostatic protection segment and the second electrostatic protection segment is not limited to including only two electrostatic protection segments. Depending on the antenna scheme and / or folding state of different electronic devices, it can be divided into three or more electrostatic protection segments. Depending on whether the position of the ground connection point connected to the first electrostatic protection layer is located within the antenna setting area 100, the static electricity on the second electrostatic protection layer can be discharged by electrostatic coupling or electrostatic DC.

[0102] Optionally, the first electrostatic protection segment 851 and the second electrostatic protection segment 853 are separated to form a gap D1, and the gap D1 is opposite to the wire structure 285; the minimum distance between the plane where the second electrostatic protection layer is located and the wire structure 2 is greater than or equal to twice the width of the gap D1.

[0103] The gap D1 formed by the separation between the two adjacent electrostatic protection segments after the second electrostatic protection layer 85 is segmented is opposite to the conductor structure 2. The size of the gap D1 should not be too large. If the gap D1 is too large, static electricity will preferentially pass through the gap D1 and enter the relative conductor structure 2, damaging the conductor structure 2. Therefore, the minimum distance between the plane where the second electrostatic protection layer 85 is located and the conductor structure 2 needs to be greater than or equal to twice the width of the gap D1. In this way, when static electricity exists in the electronic device, the static electricity will preferentially pass through the second electrostatic protection layer 85 and the corresponding first electrostatic protection layer 81, and be discharged through the electrostatic discharge path.

[0104] Optionally, the second electrostatic protection layer 85 is connected to multiple first electrostatic protection layers to be grounded through multiple electrostatic discharge paths.

[0105] In this embodiment, Figure 1 and Figure 2 As shown, the second electrostatic protection layer 85 is connected to the first electrostatic protection layer 81 and extends to the display side of the display panel 101. Multiple first electrostatic protection layers 81 are respectively arranged in the gap 4 between the shell 3 and the display panel 101. The second electrostatic protection layer 85 is connected to multiple first electrostatic protection layers 81 to form a capacitor structure, thereby being grounded through the electrostatic release path of multiple capacitor structures.

[0106] Furthermore, the electronic device also includes an antenna setting area 100; the second electrostatic protection layer 85 includes a first electrostatic protection segment 835 and a second electrostatic protection segment 836 located in the antenna setting area 100, the first electrostatic protection segment 835 and the second electrostatic protection segment 836 are separated and spaced apart, the first electrostatic protection segment 835 has a first grounding connection point, and the second electrostatic protection segment 836 has a second grounding connection point; the first grounding connection point of the first electrostatic protection segment 835 is connected to one of the first electrostatic protection layers, so that the first electrostatic protection segment 835 is grounded through a first electrostatic release path; the second grounding connection point of the second electrostatic protection segment 836 is connected to another of the first electrostatic protection layers, so that the second electrostatic protection segment 835 is grounded through a second electrostatic release path.

[0107] Combined with Figure 13 In the illustrated embodiment, the second electrostatic protection layer 85 includes a first electrostatic protection segment 835, a second electrostatic protection segment 836, and a third electrostatic protection segment 834. The first and second electrostatic protection segments 835, 836 are located within the antenna installation area 100. The third electrostatic protection segment 834 is located outside the antenna installation area 100. The first and second electrostatic protection segments 835, 836 are separated and spaced apart, and each has a ground connection point. The first ground connection point of the first electrostatic protection segment 835 is connected to the first electrostatic protection layer 81, grounding the first electrostatic protection segment 835 via a first electrostatic discharge path. The second ground connection point of the second electrostatic protection segment 836 is connected to the first electrostatic protection layer 81, grounding the second electrostatic protection segment 836 via a second electrostatic discharge path. The first and second electrostatic protection segments 835, 836 are each connected to the first electrostatic protection layer 81, allowing static electricity on the segment to be discharged through an electrostatic discharge path containing a capacitor structure, achieving electrostatic coupling discharge. This not only meets electrostatic protection requirements but also minimizes the impact on the antenna.

[0108] The end of the third electrostatic protection section 834 is a grounding point, and the second electrostatic protection layer 85 at the grounding point is in direct contact with the housing 3 and electrically connected to the ground.

[0109] Optionally, the second electrostatic protection layer 85 is a continuously extended conductive layer superimposed on the display side of the display panel 101, and the second electrostatic protection layer 85 has a first grounding connection point a and a second grounding connection point b arranged at intervals, the first grounding connection point a is connected to one of the first electrostatic protection layers, and the second grounding connection point b is connected to another of the first electrostatic protection layers; the distance between the first grounding connection point a and the second grounding connection point b is less than or equal to 14 mm.

[0110] exist Figure 12 In the illustrated embodiment, the second electrostatic protection layer 85 is not segmented, and a plurality of spaced-apart ground connection points may be provided thereon, each ground connection point being grounded via the aforementioned electrostatic discharge path.

[0111] exist Figure 14 In the illustrated embodiment, the second electrostatic protection layer 85 includes a first electrostatic protection segment 851 and a second electrostatic protection segment 853, and a gap D1 is formed between the first electrostatic protection segment 851 and the second electrostatic protection segment 853. The first electrostatic protection segment 851 is a continuously extending segment in the second electrostatic protection layer, and the first electrostatic protection segment 851 may include multiple grounding connection points. That is, the first electrostatic protection segment 851 includes a first grounding connection point a and a second grounding connection point b. The first grounding connection point a is connected to a first electrostatic protection layer 81, and the second grounding connection point b is connected to another first electrostatic protection layer 81. The distance D2 between the first grounding connection point a and the second grounding connection point b is less than or equal to 14 mm.

[0112] The first electrostatic protection segment 851 is connected to the two first electrostatic protection layers 81, respectively. Thus, the same second electrostatic protection layer can form corresponding electrostatic discharge paths for the capacitor structure C at the first ground connection point a and the second ground connection point b. Thus, static electricity released by the electronic device to the second electrostatic protection layer can be grounded through the electrostatic discharge paths of the multiple capacitor structures C, and discharged to the housing 3, achieving electrostatic coupling discharge. This not only meets the electrostatic protection requirements but also minimizes the impact on the antenna.

[0113] The first electrostatic protection section 851 is located in the antenna setting area 100, so the distance D2 between the first ground connection point a and the second ground connection point b of the first electrostatic protection section 851 cannot be too large, especially at the two ends of the first electrostatic protection section 851. Figure 15As shown, the first ground connection point a and the second ground connection point b on the same first electrostatic protection segment 851 respectively form a capacitor structure C, which is equivalent to two capacitor structures C in parallel. The equivalent capacitance formed at the end of the first electrostatic protection segment 851 is larger, and accordingly, the equivalent electrical length of the first electrostatic protection segment 851 is significantly lengthened. The clutter frequency generated by the first electrostatic protection segment 851 is likely to fall into the working frequency band of the antenna, affecting the antenna performance. For example, if the length of the first electrostatic protection segment 851 is 20 mm, the clutter generated is above 2.9 GHz. Therefore, the distance D2 between the first ground connection point a and the second ground connection point b should not be too large, and needs to be less than or equal to 14 mm. This distance is the minimum resonant length of the highest frequency (for example, B41), thereby preventing the clutter generated by the first electrostatic protection layer from falling into the highest frequency band.

[0114] Optionally, the electronic device also includes an antenna setting area 100 provided with an antenna, and the second electrostatic protection layer 85 is a continuous conductive layer superimposed on the display side of the display panel 101, and at least a portion of the second electrostatic protection layer 85 is superimposed relative to the antenna setting area 100, the first end of the second electrostatic protection layer 85 is grounded and located outside the antenna setting area 100, and the second end of the second electrostatic protection layer 85 away from the first end is located within the antenna setting area 100; the capacitor structure is arranged between the first end and the second end of the second electrostatic protection layer 85, and the first electrostatic protection layer is connected between the first end and the second end of the second electrostatic protection layer 85.

[0115] In this embodiment, the second electrostatic protection layer 85 is a continuously extended electrostatic protection layer, and the first end and the second end are the two ends of the corresponding branches of the electrostatic protection layer, one end is located in the antenna setting area 100, and the other end is located outside the antenna setting area 100.

[0116] like Figure 12 As shown, end 8501 of the second electrostatic shielding layer 85 is located outside the antenna installation area and is grounded. The other end 8503 of the second electrostatic shielding layer 85, which is farther away from end 8501, is located within the antenna installation area 100. At least a portion of the second electrostatic shielding layer 85 is arranged to overlap with the antenna installation area 100. End 8501 of the second electrostatic shielding layer 85 is directly in contact with the housing 3 and is grounded, thereby allowing static electricity to be discharged to the housing 3 in a direct current manner.

[0117] The capacitor structure is disposed between the end 8501 and the end 8503 of the second electrostatic protection layer 85 , that is, the first electrostatic protection layer is connected to the second electrostatic protection layer at a position other than the end 8501 and the end 8503 of the second electrostatic protection layer 85 .

[0118] By DC grounding the end 8501 of the second electrostatic protection layer 85 outside the antenna setting area, static DC release is achieved, which can provide better electrostatic protection for the display screen 1. However, the second electrostatic protection layer 85 is single-ended and grounded, which can respond to the mode of odd-numbered frequency excitation of the antenna signal. By increasing the length of the second electrostatic protection layer 85, its one-time frequency is controlled to be less than the lowest frequency band B28 of the low-frequency signal, and without affecting its first channel, the frequency multiplication resonance point can be controlled at 550MHz. Under ideal conditions, the triple frequency excited by the second electrostatic protection layer 85 is at 1650MHz, which is lower than the first channel of B3 (1710MHz); the quintuple frequency excited by the second electrostatic protection layer 85 is at 2750MHz, which is higher than the last channel of B41 (2690MHz), but the distance is very close, and the actual assembly and mass production process differences can easily cause the triple and quintuple frequency clutter frequencies excited by the second electrostatic protection layer 85 to deviate to the working frequency band of the antenna.

[0119] To this end, the capacitance between the electrostatic protection layer and the shell is increased through the capacitor structure of the embodiment of the present application to control the odd multiples of the excitation of the second electrostatic protection layer to fall outside the working frequency band of the antenna signal. While ensuring that the second electrostatic protection layer provides electrostatic protection for the display screen, the impact of the electrostatic protection layer on the antenna is minimized.

[0120] like Figures 16 to 18 As shown, compared to the current distribution of the single-frequency current, the triple-frequency current distribution has one more electric field strength point and one more current strength point, while the quintuple-frequency current distribution has two more electric field strength points and two more current strength points. The end 8501 of the second electrostatic shielding layer 85 corresponds to the strongest current point 8513 (represented by a rectangle in the figure), and the end 8503 of the second electrostatic shielding layer 85 corresponds to the strongest electric field point 8511 (represented by a circle in the figure).

[0121] In one embodiment, optionally, in response to the antenna signal, there is at least one electric field strength point position and at least one current strength point position between the first end and the second end of the second electrostatic protection layer, and the capacitor structure is arranged at the electric field strength point position or the current strength point position.

[0122] exist Figure 17 and Figure 18In the illustrated embodiment, the end 8501 of the second electrostatic shielding layer 85 is the first end, and the other end 8503 of the second electrostatic shielding layer 85 is the second end. In response to the antenna signal, the end 8501 of the second electrostatic shielding layer 85 generates a current strength point 8513, and the end 8503 of the second electrostatic shielding layer 85 generates an electric field strength point 8511. An electric field strength point 8512 and a current strength point 8514 are also formed between the end 8501 and the end 8503 of the second electrostatic shielding layer 85. Thus, the capacitor structure is arranged at the position corresponding to the electric field strength point 8512 or the current strength point 8514 between the two ends of the second electrostatic shielding layer 85, and the first electrostatic shielding layer 81 is connected to the second electrostatic shielding layer 85 at the position where the electric field strength point 8512 or the current strength point 8514 is located, which can effectively reduce the impact of the electrostatic shielding layer on the antenna performance.

[0123] At the position of the electric field strength point 8512 or the current strength point 8514 between the end 8501 and the end 8503 of the second electrostatic protection layer 85, a section of the first electrostatic protection layer 81 extends from the second electrostatic protection layer 85 in the direction of the shell 3. The first electrostatic protection layer 81 and the conductive part provided on the shell 3, and the dielectric layer, such as the air layer between the first electrostatic protection layer 81 and the conductive part, form a parallel plate capacitor structure. The closer the first electrostatic protection layer 81 is to the conductive part facing it, the larger the area of ​​parallel overlap, the larger the capacitance of the corresponding capacitor structure formed, and the stronger the loaded capacitance. By shortening the distance between the first electrostatic protection layer 81 and the conductive part, the capacitance between the second electrostatic protection layer and the shell 3 is increased, thereby lowering the resonant frequency of the electrostatic protection layer and controlling the generated clutter to fall outside the antenna working frequency band, thereby minimizing its impact on the antenna signal working frequency band while ensuring the electrostatic protection effect of the second electrostatic protection layer 85.

[0124] In some embodiments, in response to the antenna signal, the second electrostatic protection layer has a first electric field strength point position and a second electric field strength point position, the second electric field strength point position is located at the first end of the second electrostatic protection layer, the first electric field strength point position is located between the first end and the second end of the second electrostatic protection layer, the capacitor structure is arranged at the first electric field strength point position, and the first electrostatic protection layer is connected to the first electric field strength point position.

[0125] exist Figure 17 In the embodiment shown, for the tripled frequency excitation of the second electrostatic shielding layer 85, in addition to the second electric field strength point 8511 at the end 8503 of the second electrostatic shielding layer, the second electrostatic shielding layer 85 also excites a first electric field strength point 8512 located between the end 8501 and the end 8503 of the second electrostatic shielding layer 85.

[0126] The tripled frequency excited by the second electrostatic shield 85 must be controlled below 1710 MHz and must not affect the B3 primary channel. Therefore, connecting the first electrostatic shield 81 to the first electric field strength point 8512 between the ends 8501 and 8503 of the second electrostatic shield 85 forms a capacitive structure, minimizing the impact on antenna performance.

[0127] In some embodiments, in response to the antenna signal, the second electrostatic protection layer has at least one electric field strength point position and at least one current strength point position, and the second end of the second electrostatic protection layer is the electric field strength point position; the capacitor structure is arranged at the current strength point position between the first end and the second end of the second electrostatic protection layer, and the first electrostatic protection layer is connected to at least one of the current strength point positions.

[0128] exist Figure 18 In the embodiment shown, for the fifth frequency of the excitation of the second electrostatic shielding layer 85, in addition to the second electric field strength point 8511, the first electric field strength point 8512 and the current strength point 8513 located at the end 8501 of the second electrostatic shielding layer, the second electrostatic shielding layer 85 also excites a current strength point 8514 located between the end 8501 and the end 8503 of the second electrostatic shielding layer 85.

[0129] For the fifth harmonic frequency excited by the second electrostatic shield 85, the frequency of the fifth harmonic frequency needs to be raised to avoid falling into the highest frequency B41 band. This approach is opposite to the approach in the triple frequency embodiment described above. Therefore, the first electrostatic shield 81 is connected to the current strong point 8514 located between the end 8501 and the end 8503 of the second electrostatic shield 85 to form a corresponding capacitor structure.

[0130] There are two current strong points 8514 between the end 8501 and the end 8503 of the second electrostatic protection layer 85. The two current strong points 8514 are respectively provided with the aforementioned capacitor structure. The second electrostatic protection layer 85 is connected to the first electrostatic protection layer 81 in the capacitor structure at the locations of the two current strong points 8514. The closer the first electrostatic protection layer 81 is to the conductive part facing it, the larger the area of ​​parallel overlap, the larger the capacitance of the corresponding capacitor structure, and the stronger the loaded capacitance. The second electrostatic protection layer is shortened by the additional first electrostatic protection layer 81 to the conductive part, thereby increasing the capacitance between the electrostatic protection layer and the shell at the strongest current point, thereby raising the resonant frequency of the fifth frequency of the electrostatic protection layer, controlling the clutter to fall outside the band of B41, and minimizing its impact on the working frequency band of the antenna signal while ensuring that the second electrostatic protection layer 85 achieves its electrostatic protection effect.

[0131] In some embodiments, the electronic device may include a first capacitor structure and a second capacitor structure, wherein the first capacitor structure is arranged at the first end of the second electrostatic protection layer, the first end of the second electrostatic protection layer is connected to the first electrostatic protection layer in the first capacitor structure, and the first end of the second electrostatic protection layer is grounded through the first capacitor structure; the second capacitor structure is arranged between the first end and the second end of the second electrostatic protection layer, and the second electrostatic protection layer is connected through the first electrostatic protection layer in the second capacitor structure to increase the capacitance between the second electrostatic protection layer and the shell.

[0132] Specifically, in Figures 16 to 18 In an embodiment, the end 8501 of the second electrostatic shielding layer 85 located outside the antenna installation area 100 can be grounded via an electrostatic discharge path. That is, the end 8501 of the second electrostatic shielding layer 85 is grounded via the electrostatic discharge path formed by the first capacitor structure, and the portion of the second electrostatic shielding layer 85 located between the end 8501 and the other end 8503 thereof is increased in capacitance between the second electrostatic shielding layer and the housing via the second capacitor structure, thereby reducing the impact on antenna performance.

[0133] It is understandable that the second capacitor structure can be set at a current strong point or an electric field strong point according to the antenna signal type. For details, please refer to the aforementioned Figure 17 and Figure 18 The relevant description will not be repeated here.

[0134] This embodiment increases the capacitance between the second electrostatic protection layer 85 and the shell 3 by arranging the second capacitor structure between the end 8501 and the other end 8503 of the second electrostatic protection layer 85, thereby reducing the influence of the electrostatic protection layer on the working frequency band of the antenna signal.

[0135] When the second electrostatic protection layer conducts static electricity through the electrostatic discharge path of the first capacitor structure, the second electrostatic protection layer can also pass through the second capacitor structure so that the even-harmonic frequency interference excited by the second electrostatic protection layer falls outside the working frequency band of the antenna signal.

[0136] In an embodiment of the present application, the electronic device includes a display screen, a shell, a first electrostatic protection layer and a dielectric layer. The display screen includes a display panel and a wire structure electrically connected to the display panel. The display screen is arranged on one side of the shell. The shell is provided with a conductive part. A gap is formed between the shell and the display panel. The first electrostatic protection layer is opposite to the conductive part and is conductive. The dielectric layer is arranged between the first electrostatic protection layer and the conductive part. The first electrostatic protection layer, the dielectric layer and the conductive part form a capacitor structure, which can effectively realize electrostatic protection of the display screen wiring while minimizing the impact of the related electrostatic protection structure on the antenna performance.
