Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel display devices, such as organic light emitting display devices, are prone to degradation due to moisture penetration, necessitating an effective sealing structure to protect the display unit.
Innovation Solution
A flat panel display device with a metal sealing substrate comprising a first and second metal layer, an insulating layer, and a sealing member, where the metal sealing substrate is folded to overlap itself, allowing for a power supply device to be affixed via magnetic force, ensuring the display unit is sealed and powered effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing structure is implemented to protect the display unit from moisture penetration, then the reliability of the display device is improved, but the device complexity increases
Solution Approach 1:
The sealing substrate employs a composite structure consisting of multiple metal layers (first and second metal layers) stacked with an insulating layer in between. This composite material approach provides effective moisture sealing while maintaining structural integrity and enabling flexible device design.
Solution Approach 2:
The sealing substrate is divided into multiple functional layers including a first metal layer, an insulating layer, and a second metal layer. This segmentation allows each layer to perform its specific function (sealing, insulation, conductivity) independently, simplifying the overall design and manufacturing process.
2Reliability
If a metal sealing substrate with multiple layers is used to provide robust sealing, then the sealing effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The insulating layer is formed between the first and second metal layers before final assembly, preparing the structure in advance to prevent short circuits and facilitate subsequent manufacturing steps. This preliminary action simplifies the overall manufacturing process by avoiding complex post-assembly operations.
Solution Approach 2:
The insulating layer acts as an intermediary element between the first and second metal layers, preventing direct electrical contact and potential short circuits. This intermediary structure simplifies manufacturing by providing a built-in protection mechanism that eliminates the need for additional insulation steps.
3Adaptability or versatility
If the metal sealing substrate is folded to overlap itself to expose metal layers for power supply, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The sealing substrate is folded along a fold line to create a three-dimensional structure where the first and second portions overlap. This dimensional transformation exposes the first metal layer in the second portion and the second metal layer in the first portion, enabling flexible power supply configuration without requiring complex lateral adjustments.
