Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels are susceptible to water vapor intrusion through perforated structures in humid environments, leading to metal corrosion and degraded display performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel uses a perforated structure for metal wiring bridging, then electrical connectivity between metal layers is improved, but water vapor intrusion and metal corrosion occur in humid environments
Solution Approach 1:
A hydrophobic member is introduced as an intermediary component at the intrusion opening to block water vapor entry. This mediator allows the perforated structure to maintain its electrical connectivity function while preventing the harmful water vapor from reaching the metal wiring, thus resolving the contradiction between electrical connectivity and water vapor resistance.
Solution Approach 2:
The harmful water vapor is extracted from the potential intrusion path by positioning the hydrophobic member at the intrusion opening. This extraction approach removes the water vapor threat before it can affect the metal wiring, allowing the perforated structure to function reliably in humid environments.
2Reliability
If the hydrophobic member blocks the intrusion opening to prevent water vapor entry, then waterproofing is improved, but water vapor accumulation may occur on the hydrophobic member surface
Solution Approach 1:
The water-absorbing member converts the harmful water vapor accumulation into a beneficial absorption process. By placing the water-absorbing member on the side of the hydrophobic member away from the intrusion opening, it captures and absorbs water vapor that condenses on the hydrophobic member surface, transforming the potential harm into a controlled absorption function.
Solution Approach 2:
The water-absorbing member acts as a secondary intermediary that manages water vapor after the hydrophobic member blocks the main intrusion path. This two-stage intermediary system ensures comprehensive protection: the hydrophobic member blocks entry, while the water-absorbing member manages any condensed vapor.
3Reliability
If the water-absorbing member is placed on the side of the hydrophobic member away from the intrusion opening, then water vapor absorption is improved, but the structure complexity increases
Solution Approach 1:
The hydrophobic member serves multiple functions: it blocks water vapor entry at the intrusion opening and simultaneously acts as a flow-guiding structure with grooves that direct water vapor to the water-absorbing member. This multi-functionality reduces overall structural complexity while maintaining effective water vapor management.
Solution Approach 2:
The flow-guiding grooves are integrated directly into the hydrophobic member structure, merging the guiding function with the blocking function. This integration eliminates the need for separate guiding structures, reducing complexity while ensuring effective water vapor transport to the absorption member.
