Description

Technical Field

[0001] This utility model relates to the field of electronic device design technology, and in particular to a display module grounding structure and electronic device. Background Technology

[0002] Currently, most electronic devices such as drawing tablets and learning tablets use touch screen input solutions. In these touch screen input solutions, users perform input operations by directly touching the display screen with their fingers or electronic pens.

[0003] In existing touchscreen input solutions, an EMR (electromagnetic resonance) sensing panel is typically placed below the display panel. The EMR sensing panel identifies the position of the pen by installing multiple coils in a flexible circuit board and sensing electromagnetic changes that occur when the electronic pen approaches.

[0004] In order for the EMR sensing panel to function properly, the existing design requires grounding the EMR sensing panel, such as... Figure 2 As shown, the grounding process specifically involves placing conductive foam or other conductive material on the bottom surface of the EMR sensing panel to contact the bottom frame of the device for grounding. In the above design, since the EMR sensing panel extends outward from the display panel with an extension end near the device's side frame, let 'a' be the distance from the end of the extension end away from the EMR sensing panel to the end of the display panel near the side frame. The larger 'a' is, the greater the distance between the side frame and the display panel. This results in a smaller screen-to-body ratio (the proportion of the screen to the surface area of ​​the device frame), severely impacting the user's viewing experience.

[0005] 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

The device frame includes a bottom frame and a side frame, wherein the bottom frame is located on the side of the EMR sensing panel away from the display panel, and the side frame is located on the outside of the display panel and the EMR sensing panel; The EMR sensing panel includes a main body and an extension extending from the main body to the outside of the display panel. The extension is bent away from the side frame to form a bent portion, which is located between the main body and the bottom frame and is grounded to the bottom frame.

[0008] Optionally, the bending portion includes a bending sub-portion and a horizontal sub-portion; One end of the curved sub-section is connected to the main body, and the other end is connected to the horizontal sub-section.

[0020] This utility model discloses a display module grounding structure and electronic device, which is used to solve the technical problem of low screen ratio in existing electronic devices.

[0021] 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.

[0022] Please see Figure 1 This utility model provides a display module grounding structure, including a display module and a device frame; The display module is assembled in the device frame. The display module includes an EMR sensing panel 3 and a display panel 4, wherein the display panel 4 is disposed on the EMR sensing panel 3. The device frame includes a bottom frame 1 and a side frame 2, wherein the bottom frame 1 is located on the side of the EMR sensing panel 3 away from the display panel 4, and the side frame 2 is located on the outside of the display panel 4 and the EMR sensing panel 3; The EMR sensing panel 3 includes a main body 301 and an extension end extending from the main body 301 to the outside of the display panel 4. The extension end is bent away from the side frame 2 to form a bent portion. The bent portion is located between the main body 301 and the bottom frame 1 and is grounded to the bottom frame 1.

[0023] It should be noted that the display panel 4 in this embodiment is specifically an OLED display panel; the device frame in this embodiment is a metal frame to achieve grounding with the EMR sensing panel 3.

[0024] In the grounding structure of the display module in this embodiment, the EMR sensing panel 3 includes a main body 301 and an extension end extending from the main body 301 to the outside of the display panel 4. The extension end is bent away from the side frame 2 to form a bent portion. The bent portion is located between the main body 301 and the bottom frame 1 and is grounded to the bottom frame 1. Through the above design, since the extension end of the EMR sensing panel 3 extending to the outside of the display panel 4 is bent to form a bent portion before being grounded to the bottom frame 1, the distance from the end of the bent portion near the side frame 2 to the end of the display panel 4 near the side frame 2 is b. This can effectively reduce the distance a mentioned in the background art (i.e., b is less than a), thereby effectively shortening the distance between the display panel 4 and the side frame 2 during assembly, thereby increasing the screen ratio of the electronic device and greatly enhancing the user's viewing experience.

[0025] Furthermore, the bending portion in this embodiment includes a bending sub-portion 302 and a horizontal sub-portion 303; One end of the curved sub-part 302 is connected to the main body 301, and the other end is connected to the horizontal sub-part 303. The horizontal sub-part 303 is parallel to the main body 301 and grounded to the bottom frame 1.

[0026] It should be noted that the bent sub-part 302 forms a U-shaped structure after bending. In addition, after bending, the horizontal sub-part 303 extends in the direction of the main body 301 and is parallel to the main body 301.

[0027] Furthermore, in this embodiment, a conductor 5 is provided between the surface of the horizontal sub-part 303 away from the main body 301 and the bottom frame 1. One surface of the conductor 5 is attached to the bottom frame 1, and the other surface is attached to the horizontal sub-part 303.

[0028] It should be noted that, through the design of the conductor 5 described above, the horizontal sub-part 303 and the bottom frame 1 can be grounded. Specifically, the conductor 5 described above can be conductive foam or other conductive materials, such as metal blocks, etc. This embodiment does not limit this, and designers can choose according to the actual situation.

[0029] Furthermore, in this embodiment, a support 6 is provided between the main body 301 and the horizontal sub-body 303; One surface of the support 6 is attached to the main body 301, and the other surface is attached to the horizontal sub-part 303.

[0030] It should be noted that, since the horizontal sub-part 303 may tilt up after bending, in order to make the horizontal sub-part 303 more stably grounded to the bottom frame 1, in the above design, a support body 6 is provided between the horizontal sub-part 303 and the main body 301. The support body 6 can continuously apply a supporting force to the horizontal sub-part 303, causing the horizontal sub-part 303 to tend to press against the bottom frame 1, thereby improving the grounding stability.

[0031] Specifically, the support 6 in this embodiment can be an adhesive backing or a plastic block. This embodiment does not limit this, and designers can choose according to the actual situation.

[0032] Furthermore, the display module in this embodiment also includes a glass panel 7; The glass panel 7 is disposed on the surface of the display panel 4 away from the EMR sensing panel 3.

[0033] It should be noted that the design of the glass panel 7 described above can protect the display panel 4.

[0034] Please see Figure 1 The present invention provides an electronic device including the above-described display module grounding structure.

[0035] Specifically, the aforementioned electronic devices may be drawing tablets, learning tablets, etc., but this embodiment does not limit them.

[0036] In this embodiment of the electronic device, the EMR sensing panel 3 includes a main body 301 and an extension end extending from the main body 301 to the outside of the display panel 4. The extension end is bent away from the side frame 2 to form a bent portion. The bent portion is located between the main body 301 and the bottom frame 1 and is grounded to the bottom frame 1. Through the above design, since the extension end of the EMR sensing panel 3 extending to the outside of the display panel 4 is bent to form a bent portion before being grounded to the bottom frame 1, the distance from the end of the bent portion near the side frame 2 to the end of the display panel 4 near the side frame 2 is b. This effectively reduces the distance a mentioned in the background art (i.e., b is less than a), thereby effectively shortening the distance between the display panel 4 and the side frame 2 during assembly, thereby increasing the screen ratio of the electronic device and greatly enhancing the user's viewing experience.

[0037] 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.
