[0002] like Figure 3 As shown, the existing display module grounding design scheme in electronic devices specifically achieves electrical connection between the backlight metal frame and the metal housing by placing conductive materials such as conductive foam and springs between the metal housing of the electronic device and the backlight metal frame of the display module, thereby achieving grounding of the display module.

[0003] In the above design, although the display module can be grounded, the conductive foam, springs and other conductive materials placed between the backlight metal frame and the metal shell will put a certain pressure on the backlight metal frame, which will cause the entire display module to be squeezed and white spots to appear, thus affecting the display effect of the display module.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

[0005] This utility model discloses a grounding structure for a display module and an electronic device, which solves the technical problem that existing display modules and electronic devices require additional conductive materials to be attached to their metal casings for grounding, and that the conductive materials can easily cause pressure on the display module, resulting in white spots on the display module.

[0007] The display module includes a backlight metal frame, and an abutment portion is formed on one side of the backlight metal frame facing the metal housing. The abutment portion and the backlight metal frame are integrally formed, and the abutment portion abuts against the metal housing.

[0008] Optionally, a plurality of abutting portions are formed on the backlight metal frame, and the plurality of abutting portions abut against the metal housing.

[0009] Optionally, the plurality of abutting portions are symmetrically arranged about the central axis of the backlight metal frame.

[0010] Optionally, the number of abutting parts is four, and the four abutting parts are respectively formed at the four corners of the backlight metal frame.

[0018] The present invention provides an electronic device including the above-mentioned display module grounding structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the grounding structure of the display module of this utility model, an abutment part is formed directly on the backlight metal frame. Since the abutment part is integrally formed with the backlight metal frame, it can conduct electricity when it comes into contact with the metal shell, thereby realizing the grounding of the display module.

Detailed Implementation

[0026] This utility model discloses a grounding structure for a display module and an electronic device, which solves the technical problem that existing display modules and electronic devices require additional conductive materials to be attached to their metal casings for grounding, and that the conductive materials can easily cause pressure on the display module, resulting in white spots on the display module.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 2 This utility model provides a display module grounding structure for electronic devices, such as smartphones, tablets, etc. The electronic device includes a metal casing 4, and the display module grounding structure includes a display module 1 and the metal casing 4 arranged opposite to each other.

[0029] The display module 1 includes a backlight metal frame 2, and an abutment portion 3 is formed on one side of the backlight metal frame 2 facing the metal housing 4. The abutment portion 3 and the backlight metal frame 2 are integrally formed, and the abutment portion 3 abuts against the metal housing 4.

[0030] It should be noted that the aforementioned display module 1 can specifically be an LCD display module.

[0031] In the grounding structure of the display module in this embodiment, an abutment part 3 is formed directly on the backlight metal frame 2. Since the abutment part 3 is integrally formed with the backlight metal frame 2, it can conduct electricity when it comes into contact with the metal shell 4, thereby realizing the grounding of the display module 1. At the same time, since this design does not require the addition of conductive materials, the display module 1 is not squeezed by conductive materials, which can effectively reduce the risk of white spots caused by the compression of the display module 1.

[0032] Furthermore, in this embodiment, a plurality of abutting portions 3 are formed on the backlight metal frame 2, and the plurality of abutting portions 3 abut against the metal housing 4.

[0033] It should be noted that by designing multiple contact parts 3, the grounding stability of the display module 1 can be improved, avoiding the situation where one of the contact parts 3 has poor contact with the metal casing 4 and causes grounding failure.

[0034] Furthermore, when there are multiple abutment portions 3, the multiple abutment portions 3 are symmetrically arranged about the central axis of the backlight metal frame 2.

[0035] For example, in one specific embodiment, the number of abutting parts 3 is four, and the four abutting parts 3 are respectively formed at the four corners of the backlight metal frame 2.

[0036] It should be noted that, through the above design, the grounding stability of the display module 1 can be improved by forming abutment parts 3 at the four corners of the backlight metal frame 2. Furthermore, since the four abutment parts 3 are evenly abutted against the metal housing 4, the metal housing 4 or the backlight metal frame 2 can also be subjected to more uniform grounding.

[0037] Furthermore, in this embodiment, the backlight metal frame 2 is stamped to form the abutting part 3, one end of the abutting part 3 is connected to the backlight metal frame 2, and the other end abuts against the metal housing 4.

[0038] It should be noted that in this embodiment, the backlight metal frame 2 can be formed into the abutting part 3 by stamping with a stamping equipment. One end of the abutting part 3 is still connected to the backlight metal frame 2, and the other end abuts against the metal shell 4.

[0039] Furthermore, to ensure the stability of the contact between the contact part 3 and the metal housing 4, the end of the contact part 3 away from the backlight metal frame 2 is bent to form a horizontal contact end 301 parallel to the plane of the metal housing 4, and the horizontal contact end 301 abuts against the metal housing 4.

[0040] It should be noted that since the horizontal contact end 301 is parallel to the plane of the metal housing 4, the above design allows the horizontal contact end 301 to be fully attached to the surface of the metal housing 4, thereby ensuring the stability of the grounding.

[0041] Furthermore, in this embodiment, a positioning structure is provided at the position corresponding to the abutment portion 3 of the metal shell 4;

[0042] The abutting part 3 abuts against the positioning structure.

[0043] Specifically, in one embodiment, the positioning structure is a positioning slot, and the abutment part 3 engages within the positioning slot.

[0044] It should be noted that, through the above design, when the abutting part 3 needs to abut against the metal housing 4, the operator can insert the end of the abutting part 3 away from the backlight metal frame 2 into the positioning slot, which can effectively prevent the abutting part 3 from detaching from the metal housing 4 and causing grounding failure, thus helping to ensure the stability of grounding.

[0045] Furthermore, the display module 1 in this embodiment includes a display area and a non-display area;

[0046] The abutting part 3 is formed at the position corresponding to the non-display area of ​​the backlight metal frame 2.

[0047] It should be noted that, through the above design, the impact of the contact part 3 on the display area of ​​the display module 1 can be avoided as much as possible.

[0048] Please see Figures 1 to 2 The present invention provides an electronic device including the above-described display module grounding structure.

[0049] The aforementioned electronic devices may specifically be smartphones, tablets, etc., but this embodiment does not limit them.

[0050] In the grounding structure of the display module of the electronic device of this utility model, an abutment part 3 is formed directly on the backlight metal frame 2. Since the abutment part 3 is integrally formed with the backlight metal frame 2, it can conduct electricity when it comes into contact with the metal shell 4, thereby realizing the grounding of the display module 1. At the same time, since this design does not require the addition of conductive materials, the display module 1 is not squeezed by conductive materials, which can effectively reduce the risk of white spots caused by the compression of the display module 1.

[0051] The above provides a detailed description of a display module grounding structure and electronic device provided by this utility model. For those skilled in the art, based on the ideas of the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
