[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] The portability of electronic devices such as smartphones will lead to a higher probability of being affected by static electricity. In mobile phones and other electronic devices, there will be static electricity problems on the sides of the screen. Static electricity discharge may cause the phone to frequently freeze, automatically shut down, have poor picture quality and volume, and have inconsistent signals. Static electricity in electronic devices will cause irreversible damage to the screen.

[0028] In the related art, the following two methods are used to protect the soft OLED screen. One is to use sparking to drain static electricity to the ground, and the other is to directly connect to the ground to drain static electricity. However, both of the above methods have obvious shortcomings:

[0029] 1. Fire jumping method

[0030] (1) Low reliability: Sparking is achieved by discharging static electricity to the ground for the second time, which can lead away static electricity. However, if the ground impedance at the sparking point cannot be guaranteed to be low enough, the reliability of the solution will be affected.

[0031] (2) Strict structure and process level: The distance between the conductive material and the ground needs to be controlled at the level of hundreds of microns, close enough but not touching, which requires a very strict process level to improve reliability.

[0032] 2. Directly connect to the ground

[0033] Direct connection to the ground directs static electricity from possible intrusion points to the ground. However, grounding in the antenna area will reduce antenna performance, make subsequent adjustments to the antenna more difficult, and may affect user experience.

[0034] From the above, it can be seen that if the method of directly connecting to the ground is adopted, the antenna performance will be reduced; if the sparking method is adopted, the reliability is poor; the distance between the sparking point and the ground needs to be close enough, the design conditions are relatively strict, and the structure and process are more difficult.

[0035] In order to solve the above technical problems, according to a first aspect of the present disclosure, an electrostatic protection device is provided. Figure 1 is a structural diagram of an electrostatic protection device according to an exemplary embodiment. Figure 2 yes Figure 1 A partial enlarged view of middle A.

[0036] like Figure 1-2 As shown, an electrostatic protection device includes: an insulating member 10 and an isolation component 20.

[0037] The insulating member 10 is extended along a first direction and has a first area 11 and a second area 12; the isolation component 20 is arranged on the insulating member 10 along the first direction, a part of the isolation component 20 is located in the first area 11, and a part of the isolation component 20 is located in the second area 12. The isolation component 20 located in the second area 12 has a grounding portion 201, and the isolation component 20 is a conductive member so that the isolation component 20 can conduct static electricity to the ground.

[0038] It should be noted that the first direction may be the length direction of the insulating member 10 or the width direction of the insulating member 10 , and the present disclosure does not make any specific limitation on this.

[0039] The insulating member 10 may be an elastic member made of non-conductive material, for example, the insulating member 10 may be plastic, or other insulating materials such as plastic. As a stable insulating material, plastic can reduce the impact on antenna performance.

[0040] The isolation component 20 may be made of a material with low impedance and good conductivity. For example, the isolation component 20 may be a metal coating coated on the surface of the insulating member 10 .

[0041] The first area 11 can be understood as an area close to the antenna. The first area 11 can be a rectangular area, a circular area, or other irregularly shaped areas, which is not specifically limited in the present disclosure.

[0042] The second area 12 can be understood as a non-antenna area. The second area 12 can be a rectangular area, a circular area, or other irregularly shaped areas, which is not specifically limited in the present disclosure.

[0043] A portion of the isolation component 20 near the antenna area is not connected to the ground plane, and a sparking method is used to dissipate static electricity, which can minimize the impact on the antenna performance. A portion of the isolation component 20 located in the non-antenna area uses a grounding method to dissipate static electricity. The isolation component 20 uses a mixed protection of sparking and grounding methods, which can minimize the impact on the antenna while ensuring static electricity dissipation, thereby improving the performance of the antenna field and thereby improving the user experience.

[0044] In the present disclosure, a portion of the isolation component 20 is located in the first area 11, and a portion of the isolation component 20 is located in the second area 12. The isolation component 20 located in the second area 12 has a grounding portion 201, and the isolation component 20 is a conductive member so that the isolation component 20 conducts static electricity to the ground. While ensuring the conduction of static electricity, the impact on the antenna is minimized, the performance of the antenna field is improved, and the user experience is improved.

[0045] In some possible implementations, such as Figure 1-2 As shown, the isolation assembly 20 includes a first conductive member 21 and a second conductive member 22 .

[0046] The first conductive member 21 is arranged in the first area 11 of the insulating member 10; and the second conductive member 22 is arranged in the second area 12 of the insulating member 10, the second conductive member 22 and the first conductive member 21 are arranged along the first direction, the first conductive member 21 has a first tip 211, the second conductive member 22 has a second tip 221 facing the first tip 211, and there is a preset spacing distance D between the first tip 211 and the second tip 221, and the grounding portion 201 is located on the second conductive member 22 so that the first conductive member 21 and the second conductive member 22 can conduct static electricity to the ground.

[0047] The first conductive member 21 may be a material with low impedance and good conductivity. For example, the first conductive member 21 may be a metal coating coated on the surface of the insulating member 10 .

[0048] The second conductive member 22 may be a material with low impedance and good conductivity. For example, the second conductive member 22 may be a metal coating coated on the surface of the insulating member 10 .

[0049] The first tip 211 and the second tip 221 may have a variety of structures. For example, the first tip 211 may be a pyramidal convex body, specifically a triangular pyramidal convex body, and the end of the pyramidal convex body is the most pointed part. In some other possible embodiments, the first tip 211 may also be a circular cone convex body. The second tip 221 may be a pyramidal convex body, specifically a triangular pyramidal convex body, and the end of the pyramidal convex body is the most pointed part. In some other possible embodiments, the second tip 221 may also be a circular cone convex body.

[0050] There is a preset spacing distance D between the first tip 211 and the second tip 221. The first conductive member 21 and the second conductive member 22 utilize the principle of conductor tip discharge. The charge at the tip of the conductor is particularly dense, and the electric field near the tip is particularly strong, so tip discharge will occur. Specifically, under the action of a strong electric field, a discharge phenomenon that occurs at the sharp part of an object is called tip discharge, which is a type of corona discharge. The principle is that the sharp part of the object has a large curvature and dense electric lines, so the potential gradient is large, causing some of the gas near it to be broken down and discharge to occur. Under the same condition of the same charge of the conductor and its surrounding environment, the sharper the tip of the conductor, the more obvious the tip effect. This is because the sharper the tip, the greater the curvature, the higher the surface charge density, and the stronger the field strength near it. On the same conductor, the part with a large curvature is the tip compared to the part with a small curvature.

[0051] In the disclosed embodiment, the first conductive member 21 is close to the antenna area and is not connected to the ground plane. The sparking method is used to conduct static electricity, which can minimize the impact on the antenna performance. In order to improve the reliability of the sparking method, a tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second static electricity conduction path of the sparking method, and the static electricity is directed to the grounded second conductive member 22. The second conductive member 22 is located in the non-antenna area, and the grounding portion 201 is located on the second conductive member 22. The grounding method is used to conduct static electricity. The isolation component 20 uses a mixed protection of the sparking method and the grounding method. While ensuring static electricity conduction, it minimizes the impact on the antenna, improves the performance of the antenna field, and thus improves the user experience.

[0052] In some possible implementations, such as Figure 2 As shown, the preset spacing distance D between the first tip 211 and the second tip 221 is no greater than 2 mm.

[0053] In order to obtain a better discharge effect, preferably, the preset spacing distance D between the first tip 211 and the second tip 221 is not greater than 2 mm. Specifically, in this embodiment, the preset spacing distance D between the first tip 211 and the second tip 221 is 2 mm.

[0054] The first tip 211 may be a pyramidal convex body, specifically a triangular pyramidal convex body, and the end of the pyramidal convex body is the most pointed part. In some other possible implementations, the first tip 211 may also be a conical convex body.

[0055] The second tip 221 may be a pyramidal convex body, specifically a triangular pyramidal convex body, and the end of the pyramidal convex body is the most pointed part. In some other possible implementations, the second tip 221 may also be a conical convex body.

[0056] Of course, the specific component structures of the first tip 211 and the second tip 221 are not limited thereto.

[0057] In the disclosed embodiment, the first conductive member 21 is close to the antenna area and is not connected to the ground plane. The sparking method is used to conduct static electricity, which can minimize the impact on the antenna performance. The second conductive member 22 is located in the non-antenna area, and the grounding portion 201 is located on the second conductive member 22. The grounding method is used to conduct static electricity. In order to improve the reliability of the sparking method, a tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second static electricity conduction path of the sparking method to lead the static electricity to the grounded second conductive member 22. The isolation component 20 adopts a mixed protection of the sparking method and the grounding method. While ensuring the conduction of static electricity, it minimizes the impact on the antenna, improves the performance of the antenna field, and thus improves the user experience.

[0058] In some possible implementations, the outer surface of the first conductive member 21 is exposed by at least a first preset distance, and the surface of the second conductive member 22 is exposed by at least a second preset distance.

[0059] The first preset distance and the second preset distance may be the same or different, and the embodiments of the present disclosure do not specifically limit this.

[0060] The first conductive member 21 near the antenna area is not connected to the ground plane, and the sparking method is used to dissipate static electricity. A tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second static electricity dissipation path of the sparking method, and the static electricity is led to the grounded second conductive member 22, thereby improving the reliability of the sparking method to dissipate static electricity. The first conductive member 21 must meet the following conditions: The surface of the first conductive member 21 must not be completely covered by other materials, and at least a first preset distance is exposed. For example, the first preset distance can be 0.02 mm.

[0061] The second conductive member 22 located in the non-antenna area adopts a more reliable grounding method to dissipate static electricity. The second conductive member 22 is connected to the ground plane through the lead-out grounding portion 201 and a colloid with good conductivity. The second conductive member 22 must meet the following conditions: the surface of the second conductive member 22 must not be completely covered by other substances and at least a second preset distance must be exposed. Exemplarily, the second preset distance can be 0.02 mm.

[0062] In the disclosed embodiment, the entire isolation component 20, except for the first conductive member 21 and the second conductive member 22 outside the antenna area, adopts a direct grounding method to improve the stability of static electricity conduction and conduct static electricity energy to the ground more reliably and accurately; the first conductive member 21 in the antenna area mainly adopts a sparking method to conduct static electricity and uses tip discharge as the second static electricity conduction path to improve the stability of static electricity conduction by the sparking method. Strictly control the structure and process to ensure the excellent performance of the antenna. The isolation component 20 adopts a mixed protection of the sparking method and the grounding method. While ensuring static electricity conduction, it minimizes the impact on the antenna, improves the performance in the antenna field, and thus improves the user experience.

[0063] In some possible implementations, such as Figure 1 As shown, the first conductive member 21 has a first end surface 212 extending along a first direction, and the impedance between the first end surface 212 and the first tip 211 is not greater than a first preset impedance.

[0064] The first end surface 212 is disposed away from the first tip 211 , and the first preset impedance is determined according to design requirements.

[0065] The first conductive member 21 near the antenna area is not connected to the ground plane, and uses a sparking method to dissipate static electricity. A tip discharge method is used between the first conductive member 21 and the second conductive member 22 as a second static electricity dissipation path of the sparking method, and static electricity is led to the grounded second conductive member 22, thereby improving the reliability of the static electricity dissipation method of the sparking method. The first conductive member 21 must also meet the following conditions: the impedance between the first end face 212 and the first tip 211 is not greater than the first preset impedance. For example, the first preset impedance can be 4Ω, that is, the impedance between the first end face 212 and the first tip 211 is not greater than 4Ω.

[0066] In the disclosed embodiment, the first conductive member 21 in the antenna area mainly uses the sparking method to dissipate static electricity and uses the tip discharge as the second static electricity dissipation path to improve the stability of the sparking method to dissipate static electricity. The structure and process are strictly controlled to ensure the excellent performance of the antenna.

[0067] In some possible implementations, such as Figure 1 As shown, the second conductive member 22 has a second end surface 222 extending along the first direction, and the impedance between the second end surface 222 and the second tip 221 is not greater than the second preset impedance.

[0068] The second end surface 222 is disposed away from the second tip 221 , and the second preset impedance is determined according to design requirements.

[0069] The second conductive member 22 located in the non-antenna area adopts a more reliable grounding method to dissipate static electricity. The second conductive member 22 is connected to the ground plane through the lead-out grounding portion 201 and a colloid with good conductivity. The second conductive member 22 also needs to meet the following conditions: the impedance between the second end face 222 and the second tip 221 is not greater than the second preset impedance. Exemplarily, the second preset impedance can be 10Ω, that is, the impedance between the second end face 222 and the second tip 221 is not greater than 10Ω.

[0070] In the disclosed embodiment, the entire isolation assembly 20, except for the first conductive member 21 and the second conductive member 22 in the antenna area, is directly grounded to improve the stability of electrostatic conduction and conduct the electrostatic energy to the ground more reliably and accurately.

[0071] In some possible implementations, such as Figure 1 As shown, the isolation component 20 has a plurality of grounding portions 201 , the plurality of grounding portions 201 are arranged at intervals, and each grounding portion 201 is electrically connected to the ground.

[0072] There may be two, three, or four or more grounding portions 201 , which is not specifically limited in the embodiments of the present disclosure.

[0073] The second conductive member 22 located in the non-antenna area adopts a more reliable grounding method to dissipate static electricity. The second conductive member 22 leads out a plurality of grounding portions 201 and is connected to the ground plane through a colloid with good conductivity.

[0074] Exemplarily, there may be two grounding parts 201, and the two grounding parts 201 are arranged at intervals on the second conductive part 22. The grounding part 201 is connected to the ground plane through a colloid with good conductivity. In the embodiment of the present disclosure, the entire isolation component 20, except for the first conductive part 21 and the second conductive part 22 in the antenna area, is directly grounded through the two grounding parts 201 to improve the stability of electrostatic conduction and conduct the electrostatic energy to the ground more reliably and accurately.

[0075] Exemplarily, there may be three grounding parts 201, and the three grounding parts 201 are arranged at intervals on the second conductive part 22. The grounding parts 201 are connected to the ground plane through a colloid with good conductivity. In the embodiment of the present disclosure, the entire isolation component 20, except for the first conductive part 21 and the second conductive part 22 in the antenna area, adopts a direct grounding method through the three grounding parts 201, thereby improving the stability of electrostatic conduction and conducting the electrostatic energy to the ground more reliably and accurately.

[0076] Exemplarily, there may be four grounding parts 201, and the four grounding parts 201 are arranged at intervals on the second conductive part 22. The grounding parts 201 are connected to the ground plane through a colloid with good conductivity. In the embodiment of the present disclosure, the entire isolation component 20, except for the first conductive part 21 and the second conductive part 22 in the antenna area, is directly grounded through the four grounding parts 201, thereby improving the stability of electrostatic conduction and conducting the electrostatic energy to the ground more reliably and accurately.

[0077] In some possible implementations, such as Figure 1 As shown, the isolation component 20 is sprayed on the surface of the insulating member 10 to form an isolation area.

[0078] Among them, by adopting this implementation, the setting mode of the isolation component 20 can be selected according to the shape and material of the electrostatic protection device in the actual process. The isolation component 20 can be a material with low impedance and good conductivity. For example, the isolation component 20 can be a metal coating coated on the surface of the insulating member 10.

[0079] In the disclosed embodiment, a portion of the isolation component 20 near the antenna area is not connected to the ground plane, and a sparking method is used to conduct static electricity, which can minimize the impact on the antenna performance. A portion of the isolation component 20 located in the non-antenna area uses a grounding method to conduct static electricity. The isolation component 20 uses a mixed protection of the sparking method and the grounding method, which can minimize the impact on the antenna while ensuring static electricity conduction, thereby improving the performance in the antenna field and further improving the user experience.

[0080] Based on the same inventive concept, according to a second aspect of the present disclosure, an electronic device is provided. Figure 3 The electronic device includes: an electrostatic protection device as in any possible implementation of the first aspect described above.

[0081] It should be noted that electronic devices may include, for example, various mobile terminals such as mobile phones and computers, tablets, personal computers, workstation equipment, large-screen devices (for example, smart screens, smart TVs, etc.), handheld game consoles, home game consoles, virtual reality devices, augmented reality devices, mixed reality devices, etc., in-vehicle smart terminals, self-driving cars, customer-premises equipment (CPE), etc.

[0082] It is understandable that the electrostatic protection device can be particularly applied to full-screen electronic devices. Of course, the electrostatic protection device can also be applied to non-full-screen electronic devices.

[0083] A portion of the isolation component 20 near the antenna area is not connected to the ground plane, and a sparking method is used to dissipate static electricity, which can minimize the impact on the antenna performance. A portion of the isolation component 20 located in the non-antenna area uses a grounding method to dissipate static electricity. The isolation component 20 uses a mixed protection of sparking and grounding methods, which can minimize the impact on the antenna while ensuring static electricity dissipation, thereby improving the performance of the antenna field and thereby improving the user experience.

[0084] In the present disclosure, a portion of the isolation component 20 is located in the first area 11, that is, close to the antenna area, that is, the first conductive member 21 is close to the antenna area and is not connected to the ground plane, and a portion of the isolation component 20 is located in the second area 12, that is, in the non-antenna area. The isolation component 20 located in the second area 12 has a grounding portion 201, and the second conductive member 22 is located in the non-antenna area. The grounding portion 201 is located on the second conductive member 22. The protection process of the electronic device is as follows Figure 4 As shown: when there is an electrostatic interference signal in the electronic device, the first conductive member 21 near the antenna area uses a sparking method to divert the static electricity, which can minimize the impact on the antenna performance. In order to improve the reliability of the sparking method, a tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second electrostatic diversion path of the sparking method, and the static electricity is led to the grounded second conductive member 22. The second conductive member 22 uses a grounding method to divert the static electricity, and the isolation component 20 uses a mixed protection of the sparking method and the grounding method. While ensuring the diversion of static electricity, it also minimizes the impact on the antenna, improves the performance of the antenna field, and avoids the situation where the electrostatic interference signal may cause damage to the electronic device screen.

[0085] In some possible implementations, such as Figure 3 As shown, the electronic device further includes: a screen 30 and a frame 40 .

[0086] The screen 30 has a wire outlet area 31; the frame 40 is located on one side of the wire outlet area 31, and the frame 40 has an antenna area 41;

[0087] The electrostatic protection device is installed in the outgoing line area 31, the first area 11 of the insulating member 10 is close to the antenna area 41, the isolation component 20 is arranged in the outgoing line area 31, a part of the isolation component 20 is located in the antenna area 41, and a part of the isolation component 20 is located in the non-antenna area. The isolation component 20 located in the non-antenna area has a grounding portion 201, and the isolation component 20 is a conductive member so that the isolation component 20 can conduct static electricity to the ground.

[0088] Among them, the screen 30 can be a flexible screen. Compared with traditional screens, the flexible screen has the characteristics of strong flexibility and bendability, providing users with a new interaction method based on the bendability, which can meet users' more needs for electronic devices. Active-matrix organic light-emitting diode (AMOLED) is a display technology. AMOLED flexible screen has the characteristics of wide display color range, low power consumption and good flexibility. Existing foldable electronic devices (such as foldable mobile phones) usually use AMOLED flexible screens as display screens.

[0089] At present, the antenna of electronic devices is often designed on the side of the screen. In order to make the signal radiation intensity of the antenna cross section 360 degrees in all directions the same to achieve the best communication effect, there must be enough open space around the antenna of the electronic device, that is, the clear area, without shielding or interference. Because metal can cause significant interference to the antenna, so in such Figure 3 In the structure diagram of the electronic device shown, the frame 40 is usually an insulating frame. One side of the screen is the wire outlet area 31, and static electricity interferes with the wire outlet area 31 relatively seriously, which can easily cause static electricity to enter along the side of the screen and damage the screen 30.

[0090] The side of the AMOLED flexible screen is the wire outlet area 31, which is prone to static electricity. Static electricity easily enters along the side of the screen 30 and is transmitted to other areas. Static electricity has the characteristics of long-term accumulation, high voltage, low power, small current and short action time. Static electricity discharge may cause the mobile phone to freeze frequently, shut down automatically, have poor picture quality and volume, and have inconsistent signals. Therefore, ESD has become an important part of electronic product quality control. ESD certification is required for electronic equipment to be put on the market, and electrostatic protection of electronic equipment is crucial.

[0091] In the embodiment of the present disclosure, a portion of the isolation component 20 is located in the first area 11, that is, close to the antenna area, that is, the first conductive member 21 is close to the antenna area and is not connected to the ground plane, and a portion of the isolation component 20 is located in the second area 12, that is, in the non-antenna area. The isolation component 20 located in the second area 12 has a grounding portion 201, and the second conductive member 22 is located in the non-antenna area. The grounding portion 201 is located on the second conductive member 22. The protection process of the electronic device is as follows Figure 4As shown: when there is an electrostatic interference signal on the screen 30 of the electronic device, the first conductive member 21 near the antenna area uses a sparking method to divert static electricity, which can minimize the impact on the antenna performance. In order to improve the reliability of the sparking method, a tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second electrostatic diversion path of the sparking method, and the static electricity is led to the grounded second conductive member 22. The second conductive member 22 uses a grounding method to divert static electricity, and the isolation component 20 uses a mixed protection of the sparking method and the grounding method. While ensuring the diversion of static electricity, it also minimizes the impact on the antenna, improves the performance of the antenna field, avoids static electricity interfering with the screen routing of the line output area 31, and thus avoids damage to the screen of the electronic device.

[0092] In some possible implementations, such as Figure 3 As shown, the insulating member 10 is a pressure edge strip made of a non-conductive material, and the pressure edge strip is used to fix the screen 30 .

[0093] There may be one or more edge pressing strips made of non-conductive material, and the embodiments of the present disclosure do not specifically limit this.

[0094] In the embodiment of the present disclosure, the edge pressure strip serves as a carrier of the isolation component 20, a portion of the isolation component 20 is located in the first area 11, that is, close to the antenna area, that is, the first conductive member 21 is close to the antenna area and is not connected to the ground plane, a portion of the isolation component 20 is located in the second area 12, that is, in the non-antenna area, the isolation component 20 located in the second area 12 has a grounding portion 201, the second conductive member 22 is located in the non-antenna area, and the grounding portion 201 is located on the second conductive member 22. The protection process of the electronic device is as follows Figure 4 As shown: when there is an electrostatic interference signal on the screen 30 of the electronic device, the first conductive member 21 near the antenna area uses a sparking method to divert static electricity, which can minimize the impact on the antenna performance. In order to improve the reliability of the sparking method, a tip discharge method is used between the first conductive member 21 and the second conductive member 22 as the second electrostatic diversion path of the sparking method, and the static electricity is led to the grounded second conductive member 22. The second conductive member 22 uses a grounding method to divert static electricity, and the isolation component 20 uses a mixed protection of the sparking method and the grounding method. While ensuring the diversion of static electricity, it also minimizes the impact on the antenna, improves the performance of the antenna field, avoids static electricity interfering with the screen routing of the line output area 31, and thus avoids damage to the screen of the electronic device.

[0095] In some possible implementations, the screen 30 is a soft screen.

[0096] Among them, the screen 30 can be a soft screen, for example, the screen 30 is a flexible screen. Compared with traditional screens, the flexible screen has the characteristics of strong flexibility and bendability, providing users with a new interaction method based on the bendability, which can meet users' more needs for electronic devices. Active-matrix organic light-emitting diode (AMOLED) is a display technology. AMOLED flexible screen has the characteristics of wide display color range, low power consumption and good flexibility. Existing foldable electronic devices (such as foldable mobile phones) usually use AMOLED flexible screens as display screens.

[0097] In the embodiment of the present disclosure, an electrostatic protection device is provided to take reliable protective measures before static electricity damages the flexible OLED screen 30, and the static electricity is effectively channeled and conducted to the ground, thereby preventing static electricity from interfering with the screen routing in the output area 31, thereby preventing damage to the screen of the electronic device and ensuring the normal use of the screen 30.
