Impact Resistance Layer for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices lack sufficient impact resistance, which can lead to damage from internal or external impacts, compromising their durability and functionality.
Innovation Solution
A display device with an impact resistance layer made of polymer materials such as thermoplastic polyurethane, polyether block amide, or silicone acrylate, applied directly on a light-blocking layer and protective film, enhancing the device's ability to withstand impacts and improve durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective film is added to the display panel, then impact resistance is improved, but device complexity increases
Solution Approach 1:
The patent combines the protective film and impact resistance layer into a single integrated structure where the impact resistance layer is formed directly on the protective film, eliminating the need for separate protective components and reducing overall structural complexity while maintaining impact resistance
Solution Approach 2:
The patent uses composite materials by combining the protective film with an impact resistance layer made of polymer materials (such as thermoplastic polyurethane, polyether block amide, or silicone acrylate), creating a multi-functional layer that provides both protection and impact resistance without requiring additional separate components
2Reliability
If the impact resistance layer is made thicker, then impact resistance is improved, but device thickness increases
Solution Approach 1:
The patent optimizes the thickness parameter of the impact resistance layer to achieve the minimum effective thickness for impact resistance while minimizing overall device thickness, using polymer materials with appropriate mechanical properties that provide sufficient protection at reduced thickness
Solution Approach 2:
The patent employs thin film structures for the impact resistance layer, using flexible polymer materials that provide adequate impact resistance at thin thicknesses, thereby avoiding significant increase in overall device thickness while maintaining protective functionality
