Display Module Sealing Layout for Easier Smartphone Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fastening method for electronic device components, such as display modules, requires large amounts of adhesive, leading to increased disassembly difficulty, damage risk, and poor repairability due to residual adhesive and complex cleaning.
Innovation Solution
The use of a first sealing member that is not in contact with the side wall of the middle frame, reducing contact areas and adhesive residue, while being disposed in gaps to fasten the display module to the bottom wall of the middle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive fully fills the space between the display module and the side wall of the middle frame, then sealing of the bent portion is implemented and narrow bezel is achieved, but disassembly difficulty increases and damage risk increases
Solution Approach 1:
The patent extracts the sealing function from the adhesive that previously filled the entire space between the display module and side wall. Instead, a dedicated first sealing member is introduced to perform sealing in the first gap between the display module and bottom wall, while the second gap between display module and side wall remains open. This separation of sealing locations reduces adhesive contact area and facilitates disassembly while maintaining sealing effectiveness.
Solution Approach 2:
The patent segments the sealing function into two separate locations: the first gap (between display module and bottom wall) and the second gap (between display module and side wall). Only the first gap is sealed with the first sealing member, while the second gap remains unsealed. This segmentation allows the display module to be firmly sealed at the bottom while reducing overall adhesive contact area, making disassembly easier and reducing damage risk.
2Strength
If large amount of adhesive is used to fasten the display module, then fastening strength is improved, but residual adhesive amount increases and cleaning difficulty increases
Solution Approach 1:
The patent applies local quality by concentrating the sealing and fastening function in a specific location (the first gap between display module and bottom wall) rather than distributing adhesive throughout the entire space. The first sealing member is precisely positioned to provide sufficient fastening strength at the critical bottom connection point, while minimizing adhesive usage elsewhere. This localized approach reduces residual adhesive and simplifies cleaning.
3Reliability
If adhesive fully fills the space between display module and middle frame, then sealing is achieved, but contact area between adhesive and components increases
Solution Approach 1:
The patent introduces a dedicated first sealing member as an intermediary component to perform the sealing function. Instead of using adhesive to fill the entire space between display module and middle frame, the first sealing member is specifically placed in the first gap to provide sealing. This intermediary approach achieves effective sealing with minimal adhesive contact area, reducing the negative effects of large-scale adhesive application.

AI summary
Embodiments of this application provide an electronic device. The electronic device includes a middle frame, a display module, and a first sealing member. The middle frame includes a bottom wall and a side wall, and the bottom wall and the side wall jointly constitute an accommodating space. The display module is mounted in the accommodating space. The display module is parallel to the bottom wall of the middle frame. The display module includes a display panel. A bent portion is formed at one end of the display panel. There is a first gap between one side that is of the display module and that includes the bent portion and the bottom wall of the middle frame, and there is a second gap between the side that is of the display module and that includes the bent portion and a first side wall of the middle frame. The first side wall is a side wall opposite to the bent portion. The first sealing member is disposed at one end that is of the display module and that includes the bent portion, and is located in the first gap. An orthographic projection of the first sealing member on the bottom wall of the middle frame is located in a range of an orthographic projection of the display module on the bottom wall of the middle frame, and the first sealing member is not in contact with the first side wall of the middle frame. According to the electronic device of this application, contact areas between the first sealing member and both of the display module and the middle frame are reduced, thereby improving repairability of the electronic device.
