Flexible Display Support Plate Bonding for Expansion and Contraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in maintaining structural integrity during contraction and expansion, as support plates tend to separate from each other, compromising the device's functionality.
Innovation Solution
A display device design featuring a first support plate with a ductile part and a second support plate with support bars, bonded together by resin layers, which includes grooves to enhance flexibility and prevent separation during expansion and contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support plates are bonded together using conventional methods, then structural integrity is maintained during normal operation, but the support plates separate from each other when the display device contracts or expands
Solution Approach 1:
The patent uses a resin layer that acts as a flexible bonding medium between support plates. This resin layer can deform and stretch during contraction and expansion of the display device, maintaining the bond between support plates while accommodating the dynamic shape changes. The resin layer essentially functions as a flexible film that transmits forces while allowing relative movement.
Solution Approach 2:
The patent employs a composite structure consisting of rigid support plates combined with a flexible resin layer. This composite material system combines the strength and rigidity of the support plates with the flexibility and elasticity of the resin, creating a hybrid structure that simultaneously achieves strong bonding and adaptability during deformation.
2Ease of operation
If the display device is designed to be flexible and deformable, then ease of carrying is improved, but structural integrity of support plates deteriorates during deformation
Solution Approach 1:
The patent divides the support structure into multiple discrete support plates connected by flexible resin layers. This segmentation allows each support plate to maintain its structural integrity independently while the resin layers between them accommodate deformation. The segmented structure prevents stress concentration that would occur in a monolithic rigid structure during flexing.
Solution Approach 2:
The patent creates a dynamic support structure where the resin layers can change their mechanical properties during deformation. The resin layers are designed to be rigid when the device is in normal state to maintain structural integrity, but become more flexible during contraction and expansion to allow deformation without compromising support plate stability.
