LCD Panel Analyzer Adhesive Integration Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD panels are prone to cracking under external forces due to structural weaknesses, compromising their reliability.
Innovation Solution
The LCD panel design includes an analyzer with adhesive properties on the active device array substrate, allowing the cover to be directly joined to the analyzer or through an optical adhesive layer, reducing the gap between the cover and the substrate and enhancing structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the conventional LCD panel structure is used with a gap between the cover and the active device array substrate, then the assembly is easier, but the structural strength and reliability are insufficient
Solution Approach 1:
The patent merges the functions of the analyzer and adhesive material into a single integrated component. The analyzer is configured to have adhesive properties, allowing it to directly join the cover to the active device array substrate, eliminating the need for separate adhesive layers and reducing structural complexity while enhancing strength.
Solution Approach 2:
The analyzer is designed to perform multiple functions: optical analysis functionality and structural adhesive functionality. By endowing the analyzer with adhesive properties, it serves both as an optical component and as a bonding agent, reducing the number of separate components needed in the structure.
2Strength
If the cover is joined to the analyzer through an optical adhesive layer, then the optical performance is maintained, but the structural strength under external force is reduced
Solution Approach 1:
The patent combines the adhesive function directly into the analyzer, eliminating the need for a separate optical adhesive layer. This integration allows the cover to be directly joined to the active device array substrate through the analyzer itself, providing stronger structural bonding while maintaining optical performance.
Solution Approach 2:
The patent removes the optical adhesive layer from the structure by incorporating adhesive properties directly into the analyzer. This extraction of the separate adhesive component eliminates the weakness it introduced while preserving the necessary optical functions.
