[0021] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0023] Furthermore, it is required that the present application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0024] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] The present application embodiment provides an electronic device. Figures 1 to 9 The electronic device 100 provided in the embodiment of the present application includes: a frame 110, a display screen 120 and a display screen decorative ring 130. Exemplarily, the electronic device 100 is a mobile phone, a smart watch or a tablet computer. In the case where the electronic device 100 is a mobile phone, for example, the frame 110 is a middle frame of the mobile phone, and the display screen decorative ring 130 is a decorative ring arranged around the periphery of the display screen 120.

[0026] In the embodiment of the present application, the frame 110 includes a metal frame portion 111 and a main body portion 112 connected to each other. The metal frame portion 111 is arranged outside the main body portion 112. The display screen 120 is stacked with the main body portion 112. The display screen decorative ring 130 surrounds the display screen 120, and the display screen decorative ring 130 is arranged between the metal frame portion 111 and the display screen 120.

[0027] A conductor layer 140 is disposed on the surface of the display screen decoration ring 130 . One end of the conductor layer 140 is located on the side of the display screen decoration ring 130 facing the display screen 120 , and the other end is located on the side of the display screen decoration ring 130 facing the metal frame portion 111 , so as to guide static electricity of the display screen 120 to the metal frame portion 111 .

[0028] In this way, in the embodiment of the present application, static electricity on the surface of the display screen 120 can be discharged to the metal frame portion 111 through the conductor layer 140, so that excessive static electricity can be prevented from accumulating on the surface of the display screen 120, thereby reducing the interference of static electricity on the display screen 120.

[0029] In addition, in the embodiment of the present application, the display screen decorative ring 130 is disposed between the metal frame portion 111 and the display screen 120, and the side of the conductor layer 140 away from the display screen 120 faces the metal frame portion 111, so that the side of the conductor layer 140 away from the display screen 120 must be away from the display screen 120. Therefore, when the static electricity transmitted from the display screen 120 to the conductor layer 140 is discharged toward the metal frame portion 111, since the side of the conductor layer 140 away from the display screen 120 is away from the display screen 120, the static electricity transmitted from the display screen 120 to the conductor layer 140 is discharged away from the display screen 120. In this way, it is possible to prevent static electricity from being discharged to the packaging portion of the display screen 120, thereby damaging the display screen 120.

[0030] Exemplarily, the packaging portion of the display screen 120 includes a flexible circuit board, a display chip, and a touch chip. The display chip and the touch chip are fixed and electrically connected to the flexible circuit board, and the flexible circuit board is electrically connected to the panel of the display screen. And the flexible circuit board can be electrically connected to the mainboard of the electronic device via a board-to-board (BTB) connector. In addition, the flexible circuit board has a bending area, and the conductor layer and the bending area of ​​the flexible circuit board are closely spaced. If the static electricity of the conductor layer is discharged to the bending area of ​​the flexible circuit board, it is easy to damage the display screen. After adopting the solution provided in the embodiment of the present application, since the static electricity conducted from the display screen 120 to the conductor layer 140 will be discharged away from the display screen 120, the problem that the static electricity of the conductor layer may be discharged to the flexible circuit board can be solved.

[0031] In some embodiments, the conductor layer 140 is a printing direct forming structure (Printing Direct Structure; PDS for short). For example, the conductor layer 140 can be made by applying a conductive silver paste to the surface of the display screen decorative ring 130 and then printing the silver paste in multiple layers. In addition, illustratively, the conductor layer 140 can also be a metal foil bonded to the surface of the display screen decorative ring 130. In the embodiments of the present application, it is only necessary to enable the conductor layer 140 to guide static electricity to the metal frame portion 111. The embodiments of the present application do not limit the specific structure of the conductor layer 140, and the specific structure of the conductor layer 140 is not listed one by one here.

[0032] refer to Figures 1 to 3 In some embodiments, the end of the conductor layer 140 facing the metal frame portion 111 is the electrostatic discharge portion 141. Figures 4 to 7 , the static discharge portion 141 is provided with a plurality of discharge tips 1410. Thus, based on the principle of tip discharge, it can be known that by providing the discharge tips 1410, the static electricity of the conductor layer 140 can be more easily discharged to the metal frame portion 111 through the discharge tips 1410. Furthermore, since the static electricity of the conductor layer 140 is more easily discharged to the metal frame portion 111, the possibility of static electricity being discharged to the packaging portion of the display screen 120 can be further reduced.

[0033] refer to Figures 4 to 6 In some embodiments, the side of the electrostatic discharge portion 141 facing the metal frame portion 111 is provided with a plurality of protrusions 1411 protruding toward the metal frame portion 111, and the protrusions 1411 form discharge tips 1410. In this way, based on the principle of tip discharge, it can be known that the end of the protrusion 1411 has a higher surface electrostatic density, so that the static electricity at the end of the protrusion 1411 is more likely to break through the air and be discharged to the metal frame portion 111.

[0034] Furthermore, in some embodiments, the cross-sectional dimension of the end of the protrusion 1411 gradually decreases in the direction toward the static discharge portion 141. In this way, the static discharge effect of the protrusion 1411 can be further improved.

[0035] Exemplarily, the protrusion 1411 includes a cylindrical portion and a hemispherical portion, the cylindrical portion protrudes from the side of the electrostatic discharge portion 141, the hemispherical portion is located on the side of the cylindrical portion away from the electrostatic discharge portion 141, and the bottom surface of the hemispherical portion is connected to the top surface of the cylindrical portion. Exemplarily, the protrusion 1411 can also be a cone protruding from the side of the electrostatic discharge portion 141. The embodiment of the present application does not limit the structure of the protrusion 1411, as long as the protrusion 1411 can discharge static electricity to the metal frame portion 111.

[0036] refer to Figure 7In some embodiments, the end of the static discharge portion 141 has a plurality of spaced sharp corners 1412, and the sharp corners 1412 form a discharge tip 1410. In this way, based on the principle of tip discharge, the end of the sharp corner 1412 has a higher surface electrostatic density, so that the static electricity at the end of the sharp corner 1412 is more likely to break through the air and be discharged to the metal frame portion 111.

[0037] Furthermore, in some embodiments, the thickness of the end of the static discharge portion 141 gradually decreases along the direction toward the outer edge of the end of the static discharge portion 141. In this way, the static discharge effect of the sharp corner portion 1412 can be further improved.

[0038] Exemplarily, the end of the electrostatic discharge portion 141 is a sawtooth structure. The end of the electrostatic discharge portion 141 is provided with a plurality of triangular sharp corners arranged at intervals. The triangular sharp corners form a discharge tip. Of course, in other embodiments, the end of the electrostatic discharge portion 141 can also be other shapes, as long as the end of the electrostatic discharge portion 141 can form a discharge tip, which will not be listed here one by one.

[0039] refer to Figure 1 In some embodiments, the display screen decorative ring 130 includes a first extension portion 131 and a second extension portion 132 connected to each other. The first extension portion 131 is located on the display side of the display screen 120, and the first extension portion 131 covers the outer periphery of the display screen 120. The second extension portion 132 protrudes relative to the first extension portion 131 along the thickness direction of the electronic device 100.

[0040] The end of the conductor layer 140 facing the display screen 120 is the static electricity introduction portion 142. The static electricity introduction portion 142 is arranged on the side of the first extension portion 131 facing the display screen 120, and the static electricity discharge portion 141 is arranged on the side of the second extension portion 132 facing the metal frame portion 111. In this way, the static electricity of the display screen 120 can first break through the air layer between the display screen 120 and the static electricity introduction portion 142, and then be transferred to the conductor layer 140 through the static electricity introduction portion 142. Furthermore, the static electricity of the conductor layer 140 can break through the air layer between the static electricity discharge portion 141 and the metal frame portion 111, and then be discharged to the metal frame portion 111 through the static electricity discharge portion 141.

[0041] refer to Figure 1 and Figure 2In some embodiments, the conductor layer 140 further includes a first connection portion 143 and a second connection portion 144. The first connection portion 143 is disposed on an end surface of the second extension portion 132. Specifically, the first connection portion 143 is disposed on an end surface of the second extension portion 132 that is opposite to the first extension portion 131. The second connection portion 144 is disposed on a side surface of the second extension portion 132 that is opposite to the metal frame portion 111. The electrostatic introduction portion 142, the second connection portion 144, the first connection portion 143 and the electrostatic discharge portion 141 are connected in sequence.

[0042] In this way, static electricity on the display screen 120 can be discharged to the metal frame portion 111 through the conductor layer 140 disposed on the bottom surface and the inner side surface of the display screen decorative ring 130. In addition, the conductor layer 140 extends through the inner side surface of the display screen decorative ring 130, which can prevent the conductor layer 140 from being exposed on the outer surface of the display screen decorative ring 130, thereby preventing the appearance of the display screen decorative ring 130 from being non-uniform.

[0043] It is understandable that since the conductor layer 140 is disposed on the bottom surface and the inner side surface of the display screen decoration ring 130 , the user's palm will not touch the conductor layer 140 , and thus the static electricity of the conductor layer 140 will not shock the user's palm.

[0044] Of course, in some embodiments, if it is not a concern whether the static electricity of the conductor layer 140 will shock the palm of the user, the conductor layer 140 can be disposed on the top surface and the outer side surface of the display screen decoration ring 130. Figure 1 The conductor layer 140 extends from the position of the display screen decorative ring 130 opposite to the display screen 120 to the top surface of the display screen decorative ring 130, and extends from right to left on the top surface of the display screen decorative ring 130. Further, the conductor layer 140 extends downward from the left end of the top surface of the display screen decorative ring 130 to the side surface of the display screen decorative ring 130, so that the conductor layer 140 is opposite to the metal frame portion 111. In this way, the conductor layer 140 can be used to discharge static electricity on the display screen 120 to the metal frame portion 111.

[0045] Of course, in some embodiments, to prevent static electricity from the conductor layer 140 from shocking the user's palm, an insulating material layer may be provided on the outer surface of the conductor layer 140 located on the top surface of the display screen decoration ring 130 .

[0046] refer to Figure 1 In some embodiments, the frame 110 further includes an insulating connection portion 113, which is connected between the main body 112 and the metal frame portion 111. The second connection portion 144 is opposite to the insulating connection portion 113. In this way, the insulating connection portion 113 can be used to prevent the second connection portion 144 from discharging static electricity into the electronic device.

[0047] refer to Figure 1 In some embodiments, the frame 110 is provided with a groove 114 at the junction of the main body 112 and the insulating connecting portion 113, and the end of the second extension portion 132 is provided in the groove 114. Exemplarily, the end of the second extension portion 132 can be bonded to the bottom of the groove 114 through adhesive. In this way, by providing the end of the second extension portion 132 in the groove 114, the second connecting portion 144 provided in the second extension portion 132 can be better directed toward the insulating connecting portion 113, so as to utilize the insulating connecting portion 113 to prevent the second connecting portion 144 from discharging static electricity into the electronic device.

[0048] refer to Figure 4 In some embodiments, the metal frame portion 111 includes a peripheral sub-portion 1111 and a base portion 1112 connected to each other. The peripheral sub-portion 1111 is disposed outside the second extension portion 132 of the display screen decorative ring 130. The static discharge portion 141 faces the metal frame portion 111. The base portion 1112 is connected to the main body portion 112 via the insulating connection portion 113.

[0049] refer to Figure 4 In some embodiments, the metal frame portion 111 needs to be anodized to generate an oxide layer on the surface of the metal frame portion 111 , thereby achieving the effect of improving the corrosion resistance, hardness and wear resistance of the metal frame portion 111 .

[0050] Exemplarily, the outer sub-portion 1111 of the metal frame portion 111 has a metal oxide layer 1113 on the side facing the electrostatic discharge portion 141. Exemplarily, when the material of the metal frame portion 111 is aluminum or aluminum alloy, the metal oxide layer 1113 is aluminum oxide. It should be noted that the metal frame portion 111 can also be made of other metal materials, which are not listed here one by one.

[0051] Since metal oxides are generally insulators, the static discharge portion 141 will break through the air layer and the metal oxide layer 1113 between the static discharge portion 141 and the metal frame portion 111 by discharging, so that the static electricity is discharged to the metal frame portion 111. In addition, the static electricity on the surface of the display screen 120 needs to break through the air layer and transfer to the conductor layer 140. It can be seen that the static electricity on the surface of the display screen 120 will be discharged to the metal frame portion 111 after two discharges.

[0052] The equivalent circuit of the discharge model of the electronic device 100 is as follows: Fig.10 As shown. A first capacitor C1 is formed between the display screen 120 and the electrostatic introduction portion 142. A second capacitor C2 and a first resistor R1 are formed between the electrostatic discharge portion 141 and the peripheral sub-portion 1111 of the metal frame portion 111. The metal frame portion 111 forms a second resistor R2. The frame 110 forms a ground terminal GND.

[0053] The size of the second capacitor C2 is related to the area of ​​the electrostatic discharge portion 141. According to the capacitance formula C=(εS) / 4πkd, where S is the area of ​​the side of the electrostatic discharge portion 141 facing the metal frame portion 111, it can be seen that the larger the area of ​​the side of the electrostatic discharge portion 141 facing the metal frame portion 111, the larger the capacitance of the second capacitor C2. The breakdown impedance formed by the first resistor R1 will be smaller, making it easier to discharge static electricity.

[0054] Combination Figure 4 , according to Paschen's Law: U = 25.4d + 6.64 (√d); E0 = U / d = 25.4 + 6.64 (√d), E = k (E0 / r 2 ), u = 0.5εE 2 , where U represents the static breakdown voltage of air in a uniform field, in kV; d represents the discharge arc length, in cm; √d represents the square root of d; E0 represents the breakdown electric field strength (source electric field), in kV / cm; k is a proportional constant; u represents the coupled electric field energy density; ε represents the dielectric permittivity; E represents the electric field strength (coupled electric field) coupled to the packaging part of the display screen 120; and r represents the distance between the packaging part of the display screen 120 and the static source electric field.

[0055] It should be noted that, illustratively, the packaging part includes a display chip and a flexible circuit board, and the display chip is electrically connected to the panel of the display screen 120 via the flexible circuit board. Since the bending part of the flexible circuit board is closest to the static discharge part 141 relative to other structures of the packaging part, the distance between the bending part of the flexible circuit board and the static discharge part 141 is used as the distance between the packaging part of the display screen 120 and the static discharge part 141.

[0056] From the above content, it can be concluded that the distance d, a key factor affecting the strength of the electrostatic discharge electric field, is mainly related to the distance between the second extension portion 132 and the peripheral sub-portion 1111, and the thickness of the electrostatic discharge portion 141, while other parameters of the electrostatic discharge portion 141 basically do not affect the distance d, so that the manufacturing difficulty of the electrostatic discharge portion 141 can be reduced. In addition, the electrostatic discharge path is transferred to the outside of the packaging portion away from the display screen 120, eliminating the possibility of static electricity directly discharging to the packaging portion of the display screen 120, and in this way, the value of the key influencing factor r of the coupling field strength can be larger, thereby improving the electrostatic protection effect of the display screen 120.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
