Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost of producing display devices are increased due to the need for different adhesion elements for various display panels, and the use of adhesive leads to difficulties in controlling the amount applied, resulting in potential panel breakage and poor bonding.
Innovation Solution
A display device design featuring an adhesion element with a through hole to control the bonding location and amount of adhesive, using a filler within the hole to ensure efficient bonding between the display panel and glass cover, with a filler-to-hole area ratio ranging from 0.5 to 0.99 for enhanced bonding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to bond display panel to glass cover, then bonding is achieved, but the fluidity of adhesive makes it difficult to control the amount applied, leading to potential panel breakage and poor bonding
Solution Approach 1:
The adhesive application area is segmented into multiple discrete adhesive layers positioned at specific locations between the anode and cathode, rather than applying adhesive uniformly across the entire surface. This segmentation allows precise control over the amount and distribution of adhesive, preventing overflow while ensuring adequate bonding at critical points.
Solution Approach 2:
The patent introduces adhesive layers as intermediary elements between the anode and cathode that serve as spacers and bonding agents simultaneously. These adhesive layers mediate the bonding process by providing controlled adhesive material at precise locations, eliminating the need for excessive adhesive application and reducing the risk of panel breakage.
2Adaptability or versatility
If different adhesion elements are used for various display panels, then bonding compatibility is improved, but the complexity and cost of production increase
Solution Approach 1:
The patent employs a universal adhesion structure where adhesive layers serve multiple functions: they act as bonding agents between substrates, as spacers to maintain electrode distances, and as insulating layers. This multi-functionality allows the same adhesive layer configuration to be used across different display panel types and sizes, eliminating the need for different adhesion elements for various panels and simplifying production.
