Flexible Display Deformation Prevention via Groove Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face deformation issues when the base substrate is removed during manufacturing, leading to wrinkles and instability in the flexible substrate, which affects the attachment of other elements and the device's rollability.
Innovation Solution
A flexible display device with a deformation-preventing layer in a receiving groove on the flexible substrate, which supports the substrate and prevents deformation, allowing for a thinner design and improved rollability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base substrate is removed from the flexible display device, then the flexible substrate can be made thinner and more flexible, but the flexible substrate becomes deformed and wrinkled
Solution Approach 1:
The flexible substrate is divided into a display area and a non-display area, with the deformation-preventing layer selectively applied only to the non-display area. This segmentation allows the display area to remain thin and flexible while the non-display area provides structural support to prevent deformation.
Solution Approach 2:
The deformation-preventing layer is applied locally only to the non-display area of the flexible substrate, not uniformly across the entire substrate. This local quality approach maintains flexibility in the display area while providing stability where needed for support.
2Volume of moving object
If the base substrate is removed, then the device can be made thinner, but elements attached to the flexible substrate become unstable and separate
Solution Approach 1:
The flexible substrate is segmented into display and non-display areas, with the deformation-preventing layer applied only to the non-display area. This allows the overall device to be thinner while maintaining reliability through localized structural support.
Solution Approach 2:
The deformation-preventing layer is applied locally to the non-display area, providing targeted reinforcement that prevents element separation and maintains reliability without increasing the overall thickness of the display area.
3Stability of the object's composition
If a deformation-preventing layer is added to the flexible substrate, then the substrate stability is improved, but the device thickness increases
Solution Approach 1:
The flexible substrate is divided into display and non-display areas, with the deformation-preventing layer selectively applied only to the non-display area. This segmentation provides stability where needed while keeping the display area thin.
Solution Approach 2:
The deformation-preventing layer is applied locally only to the non-display area, providing structural stability without uniformly increasing the thickness across the entire device, thus maintaining a thin profile in the display region.
