Stepped Support Frame Sealing for Display Screen Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen assemblies face challenges in effectively sealing the gap between the cover plate and the liquid crystal panel, which can lead to dust and moisture ingress, affecting the display quality.
Innovation Solution
The display screen assembly incorporates a first support frame with stepped portions, where the first support surface supports the cover plate and the second support surface supports the liquid crystal panel. Elastic adhesive members and a sealing member are used to secure and seal the components, with buffer members added to prevent damage from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gap between the cover plate and the liquid crystal panel is reduced to improve sealing, then dust and moisture ingress is prevented, but the manufacturing precision requirement increases
Solution Approach 1:
An elastic adhesive member is introduced as an intermediary component between the cover plate and the liquid crystal panel. This elastic member fills and seals the gap between the two rigid components, preventing dust and moisture ingress while accommodating dimensional variations and reducing the need for extremely tight manufacturing tolerances.
Solution Approach 2:
The patent utilizes the elastic properties (hardness, thickness) of the adhesive member as adjustable parameters to optimize sealing performance. By changing the physical parameters of the elastic adhesive member, the system achieves reliable sealing without requiring extremely precise gap control during manufacturing.
2Stability of the object's composition
If the cover plate is firmly fixed to the support frame to improve structural stability, then assembly stability increases, but impact damage risk to the liquid crystal panel increases
Solution Approach 1:
Buffer members are pre-installed at the corners of the support frame before assembly. These buffer members serve as protective elements that absorb impact energy before it can reach the liquid crystal panel, thereby maintaining assembly stability while preventing impact damage.
Solution Approach 2:
The patent employs flexible buffer members (such as rubber or foam materials) at critical locations. These flexible elements provide mechanical cushioning while allowing the overall structure to maintain its stability, creating a balance between firm fixation and impact protection.
