Micro LED Display Module Side Wiring Sealing Against Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies, such as liquid crystal panels and OLED panels, face issues like slow response time, high power consumption, and vulnerability to burn-in, while micro LED panels offer improved brightness, efficiency, and durability but require effective protection against external moisture infiltration.
Innovation Solution
A display apparatus and manufacturing method featuring a micro LED panel with a substrate-mounted inorganic light-emitting devices, a thin film transistor layer, rear and side wiring, and a waterproofing system using a water-repellent material to prevent moisture permeation, including a front cover, side cover, and waterproof members to seal the module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If micro LED panels are used to improve brightness, efficiency, and durability, then display performance is enhanced, but protection against external moisture infiltration becomes critical and complex
Solution Approach 1:
The waterproofing system is divided into multiple components: a front cover, a rear cover, and a waterproof member positioned between them. This segmentation allows each component to perform its specific function while collectively providing comprehensive moisture protection for the micro LED panel.
Solution Approach 2:
A waterproof member acts as an intermediary element between the front and rear covers, specifically protecting the second end of the side wiring that extends through the substrate. This intermediary component prevents moisture infiltration at the critical wiring interface without compromising the overall display performance.
2Ease of operation
If side wiring extends along the side surface to connect TFT layer with rear wiring layer, then electrical connection is achieved, but moisture infiltration risk increases
Solution Approach 1:
The waterproof member is positioned in advance to seal around the second end of the side wiring before moisture can infiltrate. This preliminary protective action prevents harmful moisture contact with the electrical connection points, ensuring long-term reliability of the side wiring connection between the TFT layer and rear wiring layer.
3Reliability
If waterproof members are added to seal side wiring, then moisture protection is improved, but manufacturing complexity increases
Solution Approach 1:
The waterproof member is designed as a thin film or flexible sealing component that can be integrated into the existing manufacturing process. This thin film approach provides effective moisture protection for the side wiring while minimizing additional manufacturing complexity and maintaining ease of assembly.
