[0028] Figure 1 is a partial schematic diagram of an electronic device in the related art, as Figure 1 shown, the electronic device includes a screen 101, a metal strip 102, and a metal middle frame 103. The metal strip 102 includes a first part 1021, a second part 1022, and a third part 1023. The second part 1022 connects the first part 1021 and the third part 1023. The first part 1021 overlaps the screen 101. The second part 1022 is bent relative to the first part 1021. The third part 1023 is bent relative to the second part 1022 in the outward direction of the electronic device. Thus, the coupling area between the metal strip 102 and the metal middle frame 103 is substantially equal to the area of the third part 1023, which is not conducive to increasing the coupling area and affects the electrostatic protection effect.
[0029] Based on this, as Figure 2As shown, the present disclosure provides an electronic device, which includes a display panel 1, a metal frame 2, and a conductive strip 3. The metal frame 2 is assembled and fixed to the display panel 1, for example, it can be connected and fixed by an adhesive method. The electronic device may further include a rear cover connected to the metal frame 2, and related electronic components can be assembled in the space formed by the display panel 1, the metal frame 2, and the rear cover. The conductive strip 3 includes a screen pressing area 31 and a coupling area 32. The first end of the screen pressing area 31 overlaps the display panel 1, and the second end opposite to the first end extends toward the non-display side of the display panel 1. The non-display side is located on the back of the display side of the display panel 1, and the second end is connected to the coupling area 32. Through the design of the screen pressing area 31, the second end can provide sealing protection for the display panel 1. The coupling area 32 is spaced from the metal frame 2, that is, there is a certain gap between the coupling area 32 and the metal frame 2. On the one hand, static electricity can be conducted through the coupling between the coupling area 32 and the metal frame 2 to achieve static electricity protection. On the other hand, when a partial frame segment of the metal frame 2 serves as an antenna radiator, it is beneficial to maintain the clearance condition of the antenna radiator and reduce the influence of the conductive strip 3 on the radiation performance of the antenna radiator. The coupling area is arranged in a multi-segment bent shape toward the external direction of the electronic device and the rear cover direction of the electronic device. Among them, the conductive strip 3 may include a silver paste strip, and the electronic device further includes a plastic bracket. The silver paste strip is attached to the surface of the plastic bracket to fix the silver paste strip, which is particularly beneficial to the coating processing technology of the silver paste strip.
[0030] For example, as Figure 2 shown, the coupling area 32 includes a first area 321, a second area 322, and a third area 323. The first area 321 is connected to the second end of the screen pressing area 31, and the first area 321 bends from the second end of the screen pressing area 31. For example Figure 2 as shown in, the first area 321 extends toward the outside of the electronic device relative to the screen pressing area 31. The second area 322 connects the first area 321 and the third area 323, and the first area 321 and the third area 323 are substantially parallel. The second area 322 is arranged in a bent shape relative to both the first area 321 and the third area 323. Based on this, as Figure 3 shown, the coupling area 32 can be substantially arranged in a Z-shaped structure. At this time, the coupling area between the coupling area 32 and the metal frame 2 is the sum of the area of the first area 321, the area of the second area 322, and the area of the third area 323. In Figure 1 and Figure 2In the left - right direction, when the length of the coupling region 32 is equal to the length of the third part 1023, compared with the solution in the related art, the technical solution of the present disclosure is beneficial to increasing the coupling area between the coupling region 32 and the metal frame 2 and improving the electrostatic protection effect. Of course, only a three - segment bending structure with two bends provided in the coupling region 32 is taken as an example for illustration here. In other embodiments, the coupling region 32 may also be arranged in a four - segment or five - segment structure. The present disclosure does not limit this. For example, the coupling region 32 may include an odd - numbered segment structure, so that a segment structure of the coupling region 32 far from the screen - pressing region 31 can be arranged parallel to a partial surface of the metal frame 2, ensuring an increase in the coupling area compared with the solution in the related art.
[0031] Further, still taking Figure 2 as shown, the metal frame 2 includes a boss 21, and the boss 21 can be partially arranged in the opening area surrounded by the first region 321 and the second region 322. In other words, due to the relatively bent state between the first region 321 and the second region 322, an opening area can be formed by sandwiching them. Through the avoidance of this opening area, a boss 21 can be formed on the metal frame 2. On the one hand, the strength of the metal frame 2 can be enhanced through the boss 21. On the other hand, when the area corresponding to the boss 21 is used as an antenna radiator, the volume of the antenna radiator can be increased, improving the antenna performance.
[0032] In some embodiments, the interval between the coupling region 32 and the metal frame 2 is greater than or equal to 0.1 mm and less than or equal to 0.5 mm. For example, Figure 2 as shown in, the distances between the first region 321, the second region 322, and the third region 323 and the corresponding surfaces of the metal frame 2 are all within the range of 0.1 mm - 0.5 mm, which is beneficial to effectively coupling static electricity to the metal frame while reducing the influence of the conductive strip 3 on the antenna radiator. For example, the interval between the coupling region 32 and the metal frame 2 can be equal to 0.2 mm, 0.3 mm, 0.35 mm, or 0.4 mm.
[0033] In the above - mentioned various embodiments, the screen - pressing region 31 includes a pressing region 311 and at least one extension region 312 connected to the pressing region 311. The extension region 312 extends toward the non - display side of the display panel 1 and is connected to the coupling region 32. For example, Figure 2 in this, the extension region 312 is connected to the first region 321 of the coupling region, and the pressing region 311 is lapped with the display panel 1. In some embodiments, the pressing region 311 can be arranged in a long - strip structure, and one or more extension regions 312 are connected to the long - strip structure at intervals; in other embodiments, as Figure 4 shown, in order to further reduce the influence of the conductive strip 3 on the antenna radiator, at least one screen - strip slit 3111 is provided in the pressing region 311. For exampleFigure 4 The pressing area 311 is provided with three strip breaks, and the pressing area 311 is divided into four sub-pressing areas by the three strip breaks. Each sub-pressing area is connected to at least one extension area 312, and the extension areas 312 and the coupling areas 32 are connected in one-to-one correspondence.
[0034] Of course, only the case where the pressing area 311 is provided with three strip breaks is taken as an example for illustration here. In other embodiments, the pressing area 311 may of course include other numbers of strip breaks, such as one strip break or two strip breaks, etc. The present disclosure does not limit this.
[0035] In some embodiments, the metal frame 2 includes a bottom frame segment 22. Since the COP area of the display panel 1 is located at the bottom of the electronic device, it is necessary to use the bottom frame segment 22 to perform electrostatic protection on the COP area of the display panel 1. Therefore, the conductive strip 3 can be arranged close to the bottom frame segment 22, which can be compatible with the conventional setting positions of the COP area in related technologies and reduce the design cost. The bottom frame segment 22 is provided with antenna breaks 221, and each antenna break 221 is arranged corresponding to a strip break, so as to prevent the strip break from blocking the antenna break 221 and affecting the radiation efficiency of the bottom frame segment 22 as an antenna radiator.
