Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, especially flexible and portable ones, face challenges in achieving sufficient abrasion resistance due to the rubbing of functional layers, leading to performance deterioration, and existing methods like fluorine-based surface treatments are insufficient.
Innovation Solution
A stacked body for display devices is developed with a substrate layer and a functional layer containing fluorine, where the absolute value of charge after an eraser test is 10.0 nC or less, and includes a conductive polymer antistatic agent, impact absorbing layer, and adhesive layer, to maintain abrasion resistance and antistatic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fluorine based surface treatment agent is applied to reduce friction coefficient, then low friction property and abrasion resistance are improved, but the functional layer components are still rubbed away and performance deteriorates over time
Solution Approach 1:
The patent applies a fluorine-based surface treatment agent to the substrate layer before forming the functional layer, creating a low-friction base that protects against wear. This preliminary treatment ensures that when the functional layer is subsequently applied, it benefits from the underlying friction-reducing surface, thereby maintaining performance stability over time despite repeated rubbing.
Solution Approach 2:
The patent creates a composite structure by combining a substrate layer treated with fluorine-based surface treatment agent and a functional layer containing specific polymers. This composite approach allows the substrate to provide abrasion resistance through low friction while the functional layer maintains its protective properties, solving the contradiction between initial abrasion resistance and long-term performance stability.
2Object-affected harmful factors
If the functional layer is made harder to resist rubbing, then abrasion resistance is improved, but the friction coefficient increases and sliding property deteriorates
Solution Approach 1:
The patent applies different properties to different layers: the substrate layer is treated with fluorine-based surface treatment to provide low friction and sliding property, while the functional layer is formulated with specific polymers to provide hardness and abrasion resistance. This local differentiation of properties allows each layer to excel at its primary function without compromising the other.
Solution Approach 2:
The patent resolves the contradiction by moving the friction reduction function to the substrate layer dimension rather than trying to achieve it within the functional layer. By treating the substrate with fluorine-based surface treatment, the system achieves low friction through a different dimensional approach (substrate treatment rather than functional layer formulation), allowing the functional layer to focus on abrasion resistance.
