Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in maintaining structural strength and preventing external shock damage to the sealed part of organic light-emitting display devices, particularly in mobile and electronic products, where the sealing member's bonding strength can be compromised by external shocks.
Innovation Solution
Incorporating supplement members, such as band-shaped or pin-shaped metal or alloy layers, between the sealing portion and the circuit portion to absorb external shocks, with specific dimensions and configurations that enhance the bonding strength between substrates and distribute shock effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing member is used to bond substrates, then sealing and bonding strength is improved, but vulnerability to external shock increases
Solution Approach 1:
A cushioning layer is inserted between the sealing member and the circuit board to absorb external shocks before they reach the sealing boundary. This cushioning layer acts as a shock absorber that mitigates the impact of external forces on the bonded substrates, preventing delamination while maintaining the sealing function.
Solution Approach 2:
The cushioning layer serves as an intermediary element between the sealing member and the circuit board. It mediates the transmission of external shocks, distributing the force and preventing direct impact on the sealing interface, thereby protecting the bonded substrates from shock-induced damage.
2Strength
If sealing member thickness is increased to improve bonding strength, then structural strength is improved, but shock absorption capability deteriorates
Solution Approach 1:
By inserting a dedicated cushioning layer, the system achieves shock absorption without compromising bonding strength. The cushioning layer is positioned to absorb shocks before they reach the sealing interface, allowing the sealing member to maintain optimal thickness for bonding while the cushioning layer handles shock mitigation.
Solution Approach 2:
The sealing structure becomes a composite system combining the sealing member (for bonding) and the cushioning layer (for shock absorption). This composite structure leverages the strengths of each component: the sealing member provides strong adhesion between substrates, while the cushioning layer provides shock absorption, achieving both bonding strength and shock resistance simultaneously.
3Adaptability or versatility
If sealing member thickness is decreased to improve flexibility, then adaptability is improved, but structural strength deteriorates
Solution Approach 1:
The composite sealing structure allows the sealing member to be thin and flexible for adaptability, while the cushioning layer compensates for the reduced thickness by providing shock absorption. This enables the sealing member to conform to substrate variations and maintain flexibility without sacrificing overall structural strength.
