Display Panel Fixing Structure to Prevent Gluing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing single-layer fixing structures in display panels are prone to deformation during the gluing and assembling processes, lacking sufficient strength and stability.
Innovation Solution
A strengthened fixing structure comprising a fixing member, an auxiliary member, and supporting posts that disperse the pressing force applied during assembly, with the auxiliary member's larger surface area and strategically positioned supporting posts enhancing the structural integrity and facilitating positioning and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer fixing member is used, then the device complexity is reduced, but the strength and resistance to deformation deteriorates
Solution Approach 1:
The fixing member is divided into multiple layers (first fixing member and second fixing member) with different functions. The first fixing member provides structural support while the second fixing member enhances strength and prevents deformation. This segmentation allows each layer to be optimized for its specific purpose, resolving the contradiction between simplicity and strength.
Solution Approach 2:
The patent uses a composite structure with multiple layers of fixing members made from different materials or with different properties. The first and second fixing members are bonded together to form a composite assembly that combines the advantages of each layer, achieving both structural integrity and enhanced strength without excessive complexity.
2Ease of manufacture
If a single-layer fixing member is used, then the manufacturing process is simplified, but the manufacturing precision and assembly stability deteriorates
Solution Approach 1:
The first and second fixing members are pre-bonded together in a controlled manufacturing environment to form a pre-assembled unit with precise alignment. This preliminary action ensures that when the composite fixing member assembly is installed in the final device, the positioning accuracy and assembly stability are maintained, resolving the contradiction between ease of manufacture and manufacturing precision.
3Reliability
If glue is applied during assembly, then the bonding function is achieved, but the pressing force causes deformation of the fixing member
Solution Approach 1:
The multi-layer composite structure of the fixing members distributes the pressing force from the bonding process across multiple layers. This force distribution prevents localized deformation that would occur in a single-layer structure, while still achieving reliable bonding through the glue application process.

AI summary
A fixing structure used to connect a display panel to a housing of an electronic device during manufacture of the electronic device includes a fixing member, an auxiliary member spaced apart from the fixing member, and supporting posts disposed between the fixing member and the auxiliary member. The fixing member is to be bonded to the display panel. A projection of an outer edge of the auxiliary member on a plane of the fixing member is outside of an outer edge of the fixing member. The supporting posts and the auxiliary member are removed after the display panel is bonded to the fixing member. A method for assembling the display panel with the fixing structure is also disclosed.
