Display Device Magnetic Shielding for Packaging Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in protecting side surfaces during packaging and conveying, leading to potential damage and issues with magnetic components sticking to the packaging members, which can cause load and damage during the conveying process.
Innovation Solution
A display device design that includes a cover shield on the rear surface, magnetic units, and packaging members on the side surfaces, with a fixing plate made of ferromagnetic material to shield the magnetic field and prevent unnecessary components from sticking, allowing for easy packaging and safe conveying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packaging members are used to protect side surfaces during conveying, then protection of display panel side surfaces is improved, but magnetic components may stick to packaging members causing load and damage
Solution Approach 1:
A non-magnetic shielding plate is introduced as an intermediary between the magnetic components and the packaging members. The shielding plate blocks the magnetic field from reaching the packaging members, preventing magnetic components from sticking to them during conveying, while still allowing the packaging members to protect the display panel side surfaces.
2Reliability
If packaging members are disposed on side surfaces for protection, then safety during conveying is improved, but assembly and disassembly processes become more complex
Solution Approach 1:
The packaging structure is segmented into modular packaging members that can be independently disposed on each side surface of the display panel. Each packaging member can be separately assembled and disassembled, simplifying the overall process while maintaining comprehensive protection during conveying.
3Strength
If magnetic units are disposed on rear surface for fixing, then fixing strength is improved, but unnecessary components may stick to magnetic units during packaging
Solution Approach 1:
A non-magnetic shielding plate is positioned between the magnetic units on the rear surface and the surrounding environment during packaging. This shielding plate acts as a barrier that prevents unnecessary components from being attracted to the magnetic units, while the magnetic units continue to provide strong fixing strength for the display panel.
