Composite Supporting Member for Liquid Crystal Module Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display technologies face issues with the insufficient strength of supporting members, leading to potential damage of the liquid crystal panel during assembly or transportation due to vibrations, as rubber-based supporting members lack the necessary rigidity to securely fix the panel.
Innovation Solution
A supporting member for liquid crystal modules is designed with a T-shaped or L-shaped structure, comprising a harder plastic sub-supporting member for the liquid crystal panel and a softer rubber sub-supporting member for the light guiding plate and optical film, ensuring enhanced panel safety and vibration tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rubber-based supporting member is used, then the cost is low and the assembly process is easy, but the strength for supporting the liquid crystal panel is not enough
Solution Approach 1:
The supporting member is constructed as a composite structure combining rubber material (for flexibility and ease of assembly) and plastic material (for structural strength). This composite design allows the member to maintain ease of manufacture while achieving sufficient supporting strength to secure the liquid crystal panel during vibrations and transportation.
Solution Approach 2:
Different portions of the supporting member have different material properties: the rubber portion provides flexibility and ease of assembly, while the plastic portion provides the necessary rigidity and strength. This local differentiation of material quality resolves the contradiction between ease of manufacture and supporting strength.
2Reliability
If a typical supporting member is used, then the cost is low, but the liquid crystal panel may not be well fixed and chip on film may be damaged due to vibrations
Solution Approach 1:
The composite structure of rubber and plastic materials in the supporting member provides both flexibility for absorption of vibrations and rigidity for secure fixation of the liquid crystal panel, thereby improving reliability and protecting against vibration damage during assembly and transportation.
Solution Approach 2:
The rubber portion of the supporting member acts as a cushioning element that absorbs and mitigates vibration impacts before they can damage the liquid crystal panel or chip on film, providing beforehand protection against harmful vibrations.

AI summary
A supporting member and a liquid crystal module with the same are disclosed. The supporting member includes a first sub-supporting member for supporting a liquid crystal panel, and a second sub-supporting member for abutting against a light guiding plate and an optical film on the light guiding plate. The second sub-supporting member is arranged on the first sub-supporting member. A hardness of the first sub-supporting member is higher than the hardness of the second sub-supporting member. With the structure, the safety of the liquid crystal panel under a vibration environment is enhanced, and a tolerance range of the liquid crystal module subjected to the vibrations is guaranteed.
